Guide to Disassembling Worm Gear Box

1、 Tool preparation and safety points

Disassembling the worm gear box is like performing a precision surgery, where tools and protection are indispensable. You need to prepare:

Anti slip gloves and goggles: prevent oil stains and scratches on parts

Torque wrench: to avoid uneven force when tightening bolts

Special puller: used for smooth separation of gears and bearings

Cleaning agents and soft bristled brushes: maintaining cleanliness during component disassembly

Special reminder: Before starting work, be sure to cut off the power and hang a warning sign. Anti slip pads should be laid on oily surfaces.

2、 Detailed explanation of disassembly steps

Disassembling in order can avoid domino effect damage:

Shell separation: First remove the locating pin, then loosen the bolt, and use a top screw to evenly open the joint surface

Dismantling of gear set: mark the meshing position and lightly tap the non working surface with a copper rod

Bearing removal: Heat to around 80 ℃, and align the force point of the puller with the axis

Sealing treatment: The old sealing ring must be thoroughly cleaned of residual glue, and the groove should be wiped with alcohol

When encountering corroded parts, spray loosening agent and soak for 2 hours before operation.

3、 Assembly and debugging tips

The three golden rules for revitalizing the gearbox:

Pre lubrication: Apply the same type of grease to all moving parts, filling up to 60% of the cavity

Center test: Manually rotate the wheel for more than 3 turns and feel if there are any sticking points

Gap adjustment: Check the axial clearance of the worm gear with a feeler gauge and control it within 0.1-0.15mm

During trial operation, it is necessary to increase the speed step by step: first run at low speed for 10 minutes, then gradually increase to the working speed, and monitor the vibration and temperature rise changes during this period.
