WPS60-60-B During conventional maintenance and maintenance, the 'lubricating oil, seals, grease' must be replaced in cycles, and the core components such as 'worm gear, bearing, gasket, O-ring' must be decided based on the test results.
Regular maintenance (must replace)
Lubricating oil: New machine is replaced 300-500 hours; replacement is performed every 1500-2000 hours or 6 months, and different brands and models shall not be mixed.
Input/output shaft oil seal (skeleton oil seal): If leakage or aging is found, replace it. Install it to avoid lip damage.
Bearing grease: Replenish or replace the bearing when disassembling and inspecting it, and use suitable high-temperature and wear-resistant grease.
Disassembly inspection/overhaul (replace according to inspection)
Worm gear and worm: The wear of the tooth thickness is ≥10% to 15%, or the pitting/gluing reaches a certain level, and it is usually replaced in pairs; the description of the 'replacement threshold' in different data is slightly different, and it is recommended to refer to the actual measurement and manufacturer's manual.
Bearings: Replace when there is abnormal noise, overheating, clearance exceeding the standard or abnormal vibration; high-precision bearings of the same model are preferred.
Box joint surface gasket/O-ring: Disassemble and replace to ensure reliable sealing.
Ventilation cap/respirator: Change regularly depending on the degree of contamination to keep ventilation smooth.
Oil drain screw plug and sealing ring: Check every time the oil is changed and replaced if necessary to prevent leakage.
