- What are the preventive measures for the emulsification of lubricating oil in WPA135-60-B worm gear reducer?WPA135-60-B worm gear reducer lubricant emulsification preventive measures, core prevention principles: block water intrusion, control temperature difference condensation, ensure oil quality, standardize operation and maintenance conditions, and specifically solve the pain points of this model's large speed ratio (60) and heavy load, and the worm gear bronze material is susceptible to corrosion. The specific measures are as follows: 1. Strictly control the intrusion of external moisture and eliminate water intrusion from the source (the primary cause of emulsification). Check the sealing system regularly. The bearing end cover skeleton oil seal of this model is every 6-month inspection 1 First, focus on checking that the lip is not damaged or aged, and that the outer ring is tightly fitted. If the lip is hard or cracked, replace it immediately. Reassembly must strictly follow the specifications to ensure the direction and coaxiality to prevent water seepage in the gap between the shaft and the oil seal. The seals on the upper and lower joint surfaces of the box and the end cover joint surface are inspected every year. If they are aged or degummed, replace them in a timely manner. The bolts are evenly tightened diagonally and there is no loose gap. Maintain the breathing valve. The breathing valve is the key to moisture prevention. Clean the filter element every 3 months to remove dust.
- How to judge the emulsification degree of WPA200-40-A worm gear reducerTo judge the emulsification degree of the WPA200-40-A worm gear reducer, it mainly depends on the oil status, operating performance and testing data, as follows: 1. Oil status inspection, color and transparency: Normal oil is transparent or light amber, and after emulsification, it will become turbid, white or milky yellow, like batter. Impurities and precipitation: Take an oil sample and drop it on the filter paper. If there are metal debris or floc, it means serious emulsification. 2. Operating status monitoring Temperature: Use an infrared thermometer to measure the oil temperature. Normally it does not exceed 80℃. If it suddenly rises by more than 10℃, it may cause poor lubrication due to emulsification. Noise and Vibration: If there is a hissing or periodic friction sound during operation, it may be dry friction caused by emulsification; you also need to be vigilant if the vibration value exceeds the ISO 10816 standard (such as >8.5m/s²). 3. Oil performance testingviscosity: Use a viscometer to measure. If the viscosity drops by more than 15% or rises by more than 10%, you can
- What are the causes of premature failure of the lubrication finger of the RX67-2.7-132B5 helical gear reducer?The core reasons for the premature failure of the grease of the RX67-2.7-132B5 helical gear reducer can be attributed to the following five categories: improper grease operation, excessive temperature, mechanical shear force, oxidative deterioration, and pollution intrusion. Let me help you break it down in detail: 1. Improper grease Selection and mismatched base oil type: For example, ordinary mineral oil is used in high-temperature environments, which oxidizes quickly and has a short life. It is recommended to choose synthetic oil (such as PAO or ester). Improper consistency: If the speed is high, but too thick fat is used, it is easy to be thrown out; if the speed is low, too thin is used, and it is easy to drain. The consistency grade must be selected according to the equipment operating conditions. Insufficient additives: Insufficient extreme pressure anti-wear agent, the tooth surface is easy to glue; insufficient antioxidants, the grease deteriorates quickly at high temperatures. 2. The temperature is too high and friction generates heat: gear meshing and bearing friction will increase the temperature. After the base oil evaporates, the grease becomes hard and the lubrication performance decreases. Environmental high temperature: For example, equipment near metallurgical furnaces with temperatures exceeding
- How to deal with the emergency after the grease of RX97-2.64-22KW-M1 reducer failsRX97-2.64-22KW-M1 emergency treatment steps for reducer grease failure, core principles: first stop the machine to stop damage and prevent the fault from expanding, then perform emergency measures to ensure temporary operation, and finally make thorough rectifications to prevent recurrence, adapting to on-site sudden lubrication failure handling. 1. Immediately stop the machine and stop the loss (the first step is to prevent core components from being scrapped) 1. Emergency shutdown and power outage, hang 'No closing' Warning sign to prevent mis-starting; if accompanied by abnormal noise, high temperature, or stuck, forced start and stop is strictly prohibited to avoid broken gear teeth and bearing sintering. 2. Let it cool down until the temperature of the reducer shell drops below 40°C (to prevent hot oil burns and oil splashing) before carrying out subsequent operations. High temperature conditions Disassembly is strictly prohibited 3. Preliminary inspection of failure symptoms: observe whether there is oil or grease leakage, whether there are cracks in the casing, whether the feet are loose, listen to see if the cranking is stuck after stopping, record the fault phenomenon (abnormal noise, temperature, vibration) to provide a basis for subsequent processing 2. Emergency troubleshooting (removing failed oil
- How to choose reducer lubricating oil suitable for different ambient temperaturesThe core of selecting reducer lubricating oil is to determine the ISO VG viscosity grade according to the ambient temperature and operating temperature rise, match the oil type and additives, and follow the manufacturer's manual; low temperature gives priority to fluidity and low pour point, high temperature gives priority to oil film stability and oxidation resistance, and heavy load/impact requires an extreme pressure (EP) formula. 1. Temperature range and viscosity matching (ISO VG, mainly industrial gear oil) 2. Oil type and additive selection Normal working conditions (indoor, medium load, 10℃~40℃): Priority is given to CLP/LCKD extreme pressure industrial gear oil, mineral oil is sufficient, and it is cost-effective. Low temperature/large temperature difference (≤-10℃ or significant temperature difference between winter and summer): Choose PAO/ester synthetic gear oil with high viscosity index, low pour point, smooth start and stop, and stable oil film. High temperature/long-term continuous operation (≥40℃ or box temperature rise ≥80℃): Use high-temperature anti-oxidation and anti-coke synthetic oil or high-grade mineral oil to inhibit oxygen
- Will the wear of the output shaft cause the noise of the BWD09-87-0.37KW cycloidal pinwheel reducer to become louder?The wear of the output shaft will cause the noise of the BWD09-87-0.37KW cycloidal pinwheel reducer to become louder, and this is usually one of the common causes of abnormal noise. This is especially true when the journal, keyway, spline or mating surface with the bearing/coupling is worn. 1. The mechanism and performance of wear and noise caused by increased fit clearance: journal wear causes the fit between the inner ring of the bearing and the shaft to loosen, causing radial runout, impact and abnormal noise during operation; keyway/spline wear causes the coupling/sprocket to loosen, causing periodic impact sounds or slipping noises. Coaxiality and force imbalance: shaft bending or uneven wear destroys the meshing and support accuracy, and the cycloidal wheel and pin teeth are not meshed well, resulting in high-frequency whistling or knocking sounds; at the same time, bearing wear is aggravated, forming a vicious cycle. Typical noise: It is mostly a 'clang' impact sound at low speed, and it is a sharp whistling or irregular buzzing sound at high speed, often accompanied by increased vibration and abnormal temperature rise. 2. Investigation and treatment suggestions (1) Stop
- How to correctly connect the power supply of B13-43-5.5KW cycloidal pinwheel reducerThe power input end of the B13-43-5.5KW cycloidal pinwheel reducer is usually equipped with a three-phase asynchronous motor (5.5KW is commonly used for 380V three-phase electricity, and a few are customized for 220V single-phase, which must be subject to the motor nameplate). The power connection must comply with electrical safety regulations and motor wiring requirements. The specific steps are as follows: 1. Preparation before connection 1. Confirm that the parameters match and check the motor nameplate: focus on confirming the rated voltage (such as 380V/50Hz), rated current, and wiring method (△-shaped or Y-shaped). 5.5KW motors mostly have △-shaped wiring, which must be consistent with the power supply voltage. Check the power supply line: it needs to be equipped with a circuit breaker that matches the motor (16–20A recommended), a thermal overload relay (the setting current is set at 1.1 times the rated current of the motor), and a contactor. The line path should be no less than 2.5mm² copper core wire to ensure load-bearing capacity. 2. Tools and materials Preparation tools:
- How to fix the BLD10-17-0.75KW cycloidal pinwheel reducer after leveling the machine baseBLD10-17-0.75KW Fixing steps after leveling the base of the cycloidal pinwheel reducer BLD10 is a horizontal cycloidal pinwheel reducer (B stands for cycloidal pinwheel, L stands for vertical installation and is derived from horizontal type, D stands for motor direct connection, 10 is the frame number), 0.75KW The power model has a smaller load. The core of fixing is to ensure that the anchor bolts are evenly stressed, that the machine base has no stress deformation, and that anti-loosening measures are in place. The specific operations are as follows: 1. Confirm the leveling status and clean the fitting surface. Before fixing, use a level to re-test the longitudinal and transverse leveling of the machine base to ensure the error is ≤0.05mm/m; clean the oil stains and iron filings between the bottom surface of the reducer base, the installation foundation, and the pads to ensure that there is no gap in the joint surface to avoid warping of the machine base after tightening. 2. Anchor bolt pre-tightening (diagonal tightening method) adopts the principle of diagonal step-by-step tightening, and operates in the order of 'upper left - lower right - upper right - lower left' to avoid unilateral stress.
- What impact does motor steering have on the life of the BWED3322-121-5.5KW cycloidal pinwheel reducer?BWED3322-121-5.5KW is a medium-power two-stage horizontal cycloidal pinwheel reducer. Its internal transmission structure, sealing system, and lubrication cycle are all designed for the specified steering. Motor steering errors will accelerate component deterioration from multiple dimensions and greatly shorten the service life of the reducer. The specific effects are as follows: 1. The core transmission components accelerate wear and failure, and the service life is reduced by 50%. The meshing transmission of the above cycloidal pinwheel reducer relies on the directional surface contact between the cycloidal wheel and the pin teeth. The contact stress is designed to be evenly distributed under steering and the wear rate is controllable. When the steering is wrong, the direction of the meshing force is reversed, the contact area is transferred from the designed load-bearing surface to the non-load-bearing surface, and the local contact stress will exceed the design threshold. 1.2-1.8 times, resulting in pitting and spalling on the cycloidal gear tooth surface in a short period of time, increased wear of the needle roller bearing raceway, and deformation of the cage. For 5.5KW model, wrong steering runs 100-200 小
- How to correct the wrong direction of the motor of BWED53-187-5.5KW cycloid reducerBWED53-187-5.5KW is a medium-power two-stage horizontal cycloidal pinwheel reducer. If the motor turns incorrectly, it must be corrected by following the process of 'Stop inspection → Power off operation → Phase sequence adjustment → Steering verification → Load review' to avoid blind operation and damage to the equipment. The specific steps are as follows: 1. Emergency stop and safety confirmation. After the steering error is discovered, immediately press the emergency stop button to cut off the motor power, and it is strictly prohibited to continue running; wait until the reducer and motor are completely stopped (need to wait 5-10 minutes to ensure that the inertia is completely eliminated) before proceeding with subsequent operations. Check the connection status between the reducer and the load equipment: If it is rigidly connected, the coupling or transmission parts need to be removed to avoid damage to the reducer due to reverse impact of the load-side equipment when correcting the steering. Visually inspect the appearance of the reducer: Check whether the anchor bolts are loose, whether the oil seal is leaking, and whether there is any abnormal noise in the housing. It is initially judged that the steering error has not caused obvious component damage. 2. Cut off the power and prepare the terminals for the motor.
