How to correctly install and maintain PWU180 worm gear reducer

The correct installation and maintenance of PWU180 worm gear reducer requires ensuring "installation accuracy, proper lubrication, suitable working conditions, and regular inspections". The specific operations are as follows:
1、 Correct installation process
1. Preparation before installation

Check the appearance of the reducer, confirm that the housing, worm gear, and worm wheel are not damaged or bumped, and that the seals (oil seals, gaskets) are intact and undamaged.

Clean the installation surface (base, motor flange), remove oil stains, rust, and impurities, and ensure a smooth fitting surface.

Check the matching components, ensure that the fit tolerance between the motor output shaft and the worm shaft, and the coupling specifications meet the requirements of the equipment manual.

2. Core installation requirements

Correction of coaxiality and levelness: When connecting the motor and reducer, use a dial gauge to check coaxiality, with radial runout ≤ 0.08mm; base levelness error ≤ 0.15mm/m, to avoid poor meshing caused by shaft tilting.

Tighten bolts: Tighten the foundation bolts and connecting bolts evenly in diagonal order, and use a torque wrench to operate according to the torque specified in the manual (such as M16 bolt torque of about 60-80N · m) to prevent vibration loosening.

Gear meshing and lubrication: During assembly, ensure that the clearance between the worm gear and worm is between 0.2-0.4mm (which can be detected by a feeler gauge); After installation, add suitable lubricating oil (recommended 220 # or 320 # industrial gear oil), with the oil level between the upper and lower limits of the oil gauge, covering 1/3 of the tooth height of the worm gear.

Sealing inspection: When installing the oil seal, ensure that the lip is facing the lubricating medium and pressed in place without tilting; Apply even sealant on the joint surface to avoid oil leakage.

3. Trial operation after installation

Run without load for 30 minutes, check for any abnormal noise or vibration, and it is normal for the shell temperature to be ≤ 60 ℃.

Gradually load to 50%, 80%, and 100% of the rated load, run for 1 hour at each stage, monitor temperature (up to 85 ℃), oil leakage, and confirm that the output torque is normal.
