To determine whether the WPKS155‑60 worm gear reducer is short of oil, first use the cold shutdown state to check the oil window/oil level plug (the most accurate), and then combine the temperature, noise, leakage, and oil quality to make a comprehensive judgment. Four tricks can quickly diagnose the problem. 1. Static visual inspection (must do when the machine is powered off and cooled to room temperature) 1. Oil window observation (most commonly used) position: transparent oil mirror on the side of the box (with MIN/MAX or centerline scale). Standard: The oil level must be between MIN and MAX, preferably above the center line (approximately 2/3); when there is no scale, it is normal for the oil to submerge 1/3 to 1/2 of the worm tooth root and not submerge the worm axis. Oil shortage judgment: If the oil level is lower than MIN, the oil level cannot be seen, or there is only a small amount of oil stain, it can be directly judged as oil shortage. 2. Check the oil level screw plug (when there is no oil window). The position is: the oil level screw plug at the centerline height of the side of the box (not the oil drain/oil filling hole). Operation: Place it horizontally, turn off the power and cool down, then unscrew Read More

SBD65-PB-40-76-2.2KW Schenck said that the items that must be checked when restarting the special reducer after long-term shutdown are listed in the order that can be directly executed on site, which is concise and practical: 1. Confirm the status before shutdown and record the duration of shutdown, reason for shutdown, whether there are abnormal noises, oil leaks, overheating, large vibrations and other abnormalities before shutdown. Make sure the equipment is powered off, tagged out, and locked. Maintenance while powered on is strictly prohibited. 2. Appearance and installation inspection 1. Check the reducer body, motor, base, and torque support for corrosion, deformation, and cracking. 2. Check whether the anchor bolts and torque arm fixing bolts are loose, missing, or corroded. 3. Check whether there is any rust or sticking at the joint between the hollow shaft and the transmission shaft of the scale body. 4. Check whether the coupling/key/expansion sleeve is intact, not loose or damaged. 5. Check whether the connecting flange and the joint of the motor and reducer are displaced. 5. Check whether the installation level and coaxiality of the whole machine remain in their original state. 3. Lubrication system inspection (key points) 1 Read More

If the vent hole is blocked, it will affect the internal pressure balance of the reducer, causing lubricating oil leakage or seal damage. Timely cleaning is critical. ‌To clean the vent hole of the XLED0.55-53-3481 cycloidal pinwheel reducer, follow the steps below: 1. Stop and cool down. Make sure the reducer has stopped running for more than 30 minutes, wait until the oil temperature drops to close to the ambient temperature, and avoid hot oil spraying out or pressure release too quickly during operation. 2‌. Preliminary inspection and cleaning‌ Observe whether there is oil stain, dust or sludge accumulation around the vent hole. Use a clean cotton cloth to wipe the surface, and then use a thin iron wire or soft needle to gently clear the holes and remove internal impurities. 3. Deep cleaning (optional) If the blockage is serious, you can remove the vent cap, soak it in kerosene or cleaning agent and then scrub it to ensure that the airway is clear. Check whether the inside of the breathable cap is aged or damaged, and replace it if necessary. 4‌. Maintenance and upgrade recommendations: To prevent repeated clogging, consider installing a filter with filter function. Read More

When the output shaft of the BWY18-11-3kW cycloidal reducer with pin-type output structure is loosely connected to the load coupling, it must be stopped immediately for inspection and re-tightened according to specifications to avoid vibration, eccentricity or damage to the shaft system. If this type of loose connection is not dealt with in time, it may cause serious failures such as output shaft beating, bearing overload, or even shaft breakage. The following are systematic processing steps: 1. ‌Stop immediately and cut off the power supply‌ To prevent further damage, you should ‌stop the operation of the equipment immediately and cut off the power supply‌ to ensure safe operation. 2. ‌Disassemble and check the status of the connecting parts‌Remove the coupling and check the following items one by one: ‌Whether the pin shaft and pin hole are worn and deformed‌: Observe whether there are scratches, bends or diameter reduction on the surface of the pin shaft (the normal gap should not exceed 0.05mm); ‌Whether the coupling taper sleeve or clamping ring has failed‌: Pin shaft structures often use taper sleeve locking methods, check whether the taper surface is rusted, indented or plastically deformed; ‌Keyway and key Read More

The detection methods for output shaft bending of cycloid reducer mainly include dial indicator measurement method, micrometer measurement method, visual inspection method and vibration analysis method. Among them, dial indicator measurement method is the most accurate and commonly used. ‌1. Visual inspection method‌: Place the output shaft on a flat surface and observe whether the surface is flat or whether there is a height difference at both ends. Significant unevenness or tilt may indicate that the shaft is bent. This method is simple to operate, but has low accuracy and is suitable for preliminary judgment. ‌2. Dial indicator measurement method‌ (recommended): Preparation: Clean the surface of the output shaft to a metallic luster, place it on a V-shaped iron or special bracket to ensure that the axial movement is controlled within 0.10mm; Install the dial indicator: Fix the dial indicator on Bracket, the contact is vertically aligned with the middle position of the shaft; measurement process: slowly rotate the shaft body, record the maximum and minimum readings of the dial indicator, and half of the difference between the two is the curvature; Judgment standard: Generally, the curvature of the output shaft of the cycloidal pinwheel reducer is required to be less than Read More

After the trial operation, the JZQ500-40.17-4 gear reducer needs to be shut down for inspection, parameter recording and status confirmation to ensure that there are no abnormalities before it can be delivered for use. After the trial operation, the following steps should be followed: ‌1. Safe shutdown and cooling‌After power outage, wait for the equipment to completely stop and cool to room temperature naturally. Forced cooling is prohibited. Hang a 'No closing for equipment maintenance' warning sign on the electrical control box to ensure safe operation. 2. ‌Comprehensive inspection after shutdown‌Check whether the connecting bolts (anchor bolts, end covers, etc.) are loose and retighten if necessary. Open the observation window and check whether there are metal debris, abnormal wear or unbalanced load on the gear meshing surface. Check the status of the grease/oil. If it is black, emulsified or contains impurities, replace it immediately and replenish the oil to 1/2~2/3 of the oil mark. Check whether there is leakage at the seal, whether the oil seal is too tight or there is shaft interference problem. ‌3. Comparison of operating parameters and record archiving‌ Read More
