• What are the advantages of WPKS80-20 worm gear reducer?

  WPKS80-20 worm gear reducer is a medium-sized specification in the WP series (center distance 80mm, transmission ratio 20). Combined with its structural design and performance characteristics, it has a number of significant advantages in small and medium power transmission scenarios, as follows: 1. Transmission characteristic advantages: adapts to the efficient deceleration needs of small and medium loads. Large transmission ratio realizes transmission ratio 20 in a single stage. It belongs to the medium to large range. Reduction can be completed through single-stage worm gear meshing (no need for multi-stage gear combination). Compared with multi-stage gear reducers, it has a more compact structure and smaller size (especially short axial size). It is suitable for scenarios with limited installation space (such as small production lines and side transmission of equipment). Output torque stable center distance When the 80mm design matches the transmission ratio of 20, under the condition of input speed of 1500r/min, the output torque can reach 80-120N·m (depending on the input power), can stably drive small and medium-sized

• What are the differences in the inspection methods of different types of worm gear reducers?

  The core structure of the worm gear reducer is 'worm + worm gear' mesh transmission, but different models (such as standard horizontal WP series, vertical RV series, large CW series, micro WJ series) due to differences in design positioning (load, speed, installation scenarios), the focus, tools and key indicators of the inspection methods are different. The following is classified according to 'Model Classification' Sort out the core differences in inspection methods, and clarify common basic inspections to help accurately locate faults: 1. First clarify: 'Common basic inspections' (mandatory items) for all models. Regardless of the type of worm gear reducer, the operating status and basic performance inspection logic is consistent. The following 4 basic inspections need to be completed first, and then deepened based on the model characteristics: 1. Appearance and sealing inspection core: observe whether the shell has cracks, oil leakage (shaft end seal, box joint surface), high humidity/ Dusty environment requires additional inspection for rust prevention

• What effect does the number of reducer stages have on the load speed?

  The influence of the number of reducer stages on the load speed is mainly reflected in the transmission ratio distribution, dynamic response and efficiency attenuation. The specific analysis is as follows: 1. The mathematical relationship between transmission ratio and speed ‌ Calculation of the total reduction ratio ‌ The total reduction ratio of a multi-stage reducer is the product of the reduction ratios of each stage. For example, if a two-stage reducer has a first-stage speed ratio of 3:1 and a second-stage speed ratio of 5:1, the total speed ratio is 15:1. When the input speed is 1500r/min, the single-stage 10:1 output is 150r/min, while the three-stage 100:1 output is only 15r/min‌. ‌Speed ​​drop characteristics‌Single-stage reducer: The speed drop is small, suitable for medium and high-speed scenarios (such as conveyor belt drive). Multi-stage reducer: achieve extremely low output speed (such as 15r/min for ball mill) through step-by-step reduction. 2. Dynamic response and speed control ‌Response delay‌The increase in the number of stages will prolong the response time from the input command to the output action. For example, when a reducer with a speed ratio of 100:1 responds

• How to repair or replace the core components of the ZLY560-12.5-III hard tooth surface gear reducer after it is damaged

  For damaged repair or replacement of core components (such as gears, bearings, shafts, etc.) of the ZLY560-12.5-III hardened gear reducer, a plan needs to be formulated based on the damage type and working condition requirements. The specific process is as follows: 1. Gear damage assessment‌ Broken teeth/chips‌: Visual inspection of the fracture shape (brittle fractures are crystalline, fatigue fractures have ridges), magnetic particle inspection to detect tooth surface cracks, and ultrasonic inspection to detect internal defects. ‌Wear/pitting‌: Measure the amount of tooth thickness reduction (>5% needs to be replaced), check the contact marks on the tooth surface (unilateral meshing indicates axis misalignment)‌. 2. Bearing fault judgment: detect the clearance (rolling bearings >0.03mm need to be replaced), auscultate abnormal sounds (high-frequency sharp sounds indicate raceway damage), and check the integrity of the cage. 3. If the straightness deviation of the shafting system is >0.05mm/m, it needs to be straightened. If the journal wear exceeds 0.02mm, it can be repaired by chrome plating. If the keyway is worn, it can be re-milled. 2. Maintenance

• What methods can be used to reduce the temperature rise of ZLY630-10-1 hard tooth surface reducer?

  To reduce ZLY630-10-1 The temperature rise of the type hard tooth surface reducer needs to start from the four core dimensions of heat dissipation optimization, friction control, load matching, and structural maintenance. Combined with this type of reducer (medium hard tooth surface, single machine transmission ratio 10, center distance 630mm, commonly used in heavy-duty industrial scenarios), the following specific methods can be adopted, sorted by priority and practicality: 1. Optimize the lubrication system: reduce frictional heat generation (core method) ZLY630-10-1 As a heavy-duty hard-tooth surface reducer, frictional heat generation from gear meshing and bearing operation is the main source of temperature rise. Reasonable lubrication can directly reduce the friction coefficient and reduce heat generation. 1. Select suitable lubricating oil products a. Viscosity matching: Select industrial gear oil with appropriate viscosity according to operating conditions (load, speed, ambient temperature) to avoid 'excessive viscosity increasing friction resistance, and too low viscosity leading to lubrication failure'.

• Share some fault diagnosis and maintenance experience of WPKA120-40-B worm gear reducer

  WPKA120-40-B The fault diagnosis and maintenance of the worm gear reducer can refer to the following experience: Fault diagnosis, listening and positioning: The sound of metal friction may be due to lack of oil or oil deterioration, so you need to check the oil level in the oil window immediately and touch the box to see if it is hot; regular impact sounds may be broken teeth or damaged bearing cages, you can stop the machine and turn it manually to feel if there is any jamming; high-frequency whistling sounds may be poor alignment of the coupling, use a screwdriver to hold the bearing end and listen to the sound changes. Touch diagnosis: touch the bearing seat, and if it is hot (>70°C), the bearing may be lacking grease or damaged; touch the box joint surface, and if oil leakage or scaling occurs, the seal may be failed; touch the output shaft, if there is obvious swing, the bearing may be worn. Visual inspection: Check the lubricating oil. If the oil window is turbid, it may be oil emulsification. If the oil is black, it may be metal wear. Check the coupling. If the elastic gasket is cracked, replace it immediately. If the alignment is offset, use a ruler to roughly measure the gap.

• How to judge the wear degree of worm gear of WPKA175-15-A reducer

  Judging the degree of wear of the worm gear of the WPKA175-15-A reducer requires comprehensive visual inspection, operating status analysis and precise measurement. The specific methods are as follows: 1. Appearance inspection‌Tooth surface wear characteristics‌If scratches, grooves or accumulation of metal debris along the sliding direction appear on the tooth surface of the worm gear (copper alloy), the surface roughness will increase significantly, indicating the existence of uniform wear‌. If the tooth surface of the worm (steel) is partially polished or dented, material transfer may occur due to sliding friction. Gluing damage is manifested as metal adhesion, tearing or melted plaques on the tooth surface, which are dark brown in color. In severe cases, traces of 'bite welding' can be seen. ‌Pitting Corrosion and Cracks‌Scattered pits (pitting corrosion) or fine cracks in the tooth root appear on the tooth surface, which require observation with a magnifying glass, indicating the risk of fatigue wear‌. 2. Operating status monitoring ‌ Abnormal noise and vibration ‌ The noise in the initial stage of wear changes from 'smooth sound' to 'rustling sound', and 'piercing screams' or periodic impact sounds appear during gluing. Vibration amplitude exceeds 0

• How to perform daily maintenance on the bearings of parallel shaft F77-55-3KW-4P gear reducer

  The following is the daily maintenance plan for parallel shaft F77-55-3KW-4P gear reducer bearings, combining lubrication management, condition monitoring and preventive maintenance measures: 1. Lubrication management ‌ Grease selection and filling ‌ Use lithium-based grease (such as NLGI level 2), and the filling amount is 1/2-2/3 of the bearing cavity space. Replenish grease every 3-6 months, shortened to 1-2 months in high temperature or dusty environments. ‌Lubrication system inspection‌Check the oil level window (if available) every week to ensure that the grease is not dried out or contaminated‌. Replace the grease immediately if it is found to be discolored (blackened) or contains metal particles. 2. Operating status monitoring‌Vibration and temperature detection‌Use a vibration meter to detect the bearing parts every day. The effective value of the vibration speed should be ≤4.5mm/s‌. An infrared temperature measuring gun monitors the temperature of the outer ring of the bearing, and the temperature rise is ≤25℃ (limited to ambient temperature +40℃). ‌Judgement of sound and abnormal noise‌During normal operation, the bearing sound is even and periodic.

• What are the reasons for poor lubrication of the hard tooth surface F97-Y7.5-NA40-M4 reducer bearings?

  The essence of the poor lubrication of the hard-tooth surface F97-Y7.5-NA40-M4 reducer bearing is that 'the lubricating medium does not continuously and stably act on the rolling contact surface of the bearing according to the design requirements.' The reason can be from the lubricating medium itself, the lubrication system/ The four core dimensions of structure, installation operation, and working environment are disassembled. The specific analysis is as follows: 1. Reasons related to lubricating medium (core factors) The performance, state or Selection of the lubricating medium (usually gear oil, some bearings use grease alone) directly determines the lubrication effect, and is the most common source of failure: Lubricating oil Selection Error not pressed The manual of the reducer requires the selection of oil: for example, the misuse of low-viscosity oil (cannot form enough oil film, resulting in direct metal contact), high-viscosity oil (poor fluidity, difficult to penetrate into the tiny gap between the bearing raceway and the rolling element), or failure to use 'extreme pressure anti-wear gear oil' (hard-tooth surface reducer load is heavy, ordinary lubricating oil is easily crushed, and cannot form an effective
