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 Read More

BWED53-187-5.5KW 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. Read More

To repair uneven gear wear of ZD gear reducer, you need to follow the process of 'diagnose the root cause first - then repair according to the situation - and then prevent recurrence'. The specific operation steps are as follows: 1. Accurately locate the root cause of wear (1) Shut down and cut off the power, remove the reducer end cover and bearing end cover, take out the gear set, and check the worn parts: common uneven wear locations are one side of the gear tooth surface, tooth top or part of the tooth root. (2) Investigate core incentives: ① Installation deviation, the coaxiality of the input shaft and the output shaft is out of tolerance, or the connection with the motor and load is not concentric; ② Lubrication failure, inconsistent lubricant grade, insufficient oil volume, and oil contamination, leading to rupture of the lubricating film on the tooth surface; ③ Abnormal load, long-term unbalanced load, impact load or overload operation causes uneven stress on the gear; ④ Bearing damage, excessive bearing clearance or stuck, causing gear axis deviation; ⑤ Gear manufacturing defects, insufficient tooth profile accuracy, and uneven tooth surface hardness. (3) Record the degree of wear and tear Read More

The additional maintenance of CJY shaft-mounted reducer under special working conditions needs to be combined with the characteristics of the working conditions, and targeted strengthening of lubrication, sealing, cleaning, monitoring and other links. The following are additional maintenance measures for different special working conditions: 1. Heavy load/impact load conditions (such as metallurgy, mining equipment) (1) Shorten the lubricating oil replacement cycle: from the conventional 6~12 months to 3~4 months. Thoroughly clean the inner wall and oil passage of the gearbox during each oil change to avoid tooth surface wear caused by accumulation of iron filings and impurities. (2) Strengthen tooth surface lubrication protection: Use extreme pressure industrial gear oil (such as L-CKD 220 or 320), and add gear anti-wear agent to improve the tooth surface load-bearing capacity and prevent tooth surface gluing and pitting corrosion. (3) Increase the frequency of fastener inspections: Check the connecting bolts of the input shaft, output shaft and coupling every week, as well as the fastening bolts of the reducer installation base, and use a torque wrench to retighten according to the standard torque to prevent loosening of the bolts.

To determine whether the GSAF77-Y2.2-4P-130-M5 reducer is well lubricated, it can be comprehensively determined through three methods: operating status observation, oil detection, and component inspection. The specific points are as follows: 1. Operating parameters monitor oil temperature: Under normal working conditions, the reducer housing temperature should be stable within 60°C, with a maximum of no more than 80°C; if the oil temperature continues to be high without the influence of external heat sources, the most likely cause is insufficient lubrication, oil deterioration, or oil model mismatch. Vibration and noise: When the lubrication is good, the operating vibration amplitude is stable and within the factory standard range of the equipment, and the noise is a uniform meshing sound; if there is an abnormal sharp sound and the vibration amplitude suddenly increases, it may be poor lubrication that leads to increased gear or bearing wear. Running resistance: Manual cranking when stopped, the hand feels smooth without stuck or obvious frustration; if the cranking is laborious, it is necessary to check whether the frictional resistance of the components is increased due to lack of oil or abnormal oil viscosity. 2.

The differences in lubricating oil requirements of different types of reducers are mainly determined by four core factors: transmission structure, working condition parameters, sealing form, and installation method. The specific differences can be listed according to the following dimensions: 1. Differentiate gear reducers according to transmission type (such as cylindrical gears, bevel gears, and helical gear reducers): it is necessary to focus on load-bearing and wear resistance, and the medium-sized ones are preferred. / Heavy-duty industrial gear oil (L-CKC/L-CKD series), the viscosity needs to match the gear module and operating speed; select high-viscosity oil (460#, 680#) for heavy-duty gears with large module and low speed (such as crane reducers), and low-viscosity oil (150#, 220#) for high speed and small load. Worm gear reducer: Most worm gears are made of copper. It is necessary to avoid the active sulfur additives in the oil from corroding the copper parts. Special worm gear oil (L-CKE/P series) or gear oil without extreme pressure additives; and because the worm drive has large sliding friction and heat, Read More
