Damage and Solution of Worm Bearing

Worm bearing damage

When a failure occurs, even if the reduction box has good sealing, is often

found inside the reducer gear oil to be emulsified, bearing rust, corrosion, damage.

This is because the reducer after running for a period of time, gear oil temperature

and cooling of the condensation of water mixed with water. Of course, also with

the quality of bearing and assembly process is closely related to.

Solution method:

1、ensure the assembly quality. Can be purchased or made some special tools,removing and installing reducer parts, try to avoid using a hammer and other tools percussion; replacement gears, worm gear, try to use the original accessories and replaced in pairs; the assembly when the output shaft, attention should be paid to tolerance; to use anti-sticking agent or red lead oil protection hollow shaft, to prevent wear rust or scale with the area to remove, repair.

2、the selection of lubricating oils and additives. The worm gear reducer is generally used on220# gear oil, heavy load, frequent start, use of the environment of poor reducer, and can use a number of lubricating oil additives, so that the speed reducer in stops running gear oil is still attached to the gear surface, forming a protection film, prevent the heavy load, low speed, high torque and at the start of direct contact between the metal. Additives containing ring modulators and a leak resistant agent, so that the seal ring to maintain soft and elastic, effectively reduce the oil leakage.

3、reducer installation position selection. Location permits, try not to adopt vertical installation. Vertical installation, lubricants added more than horizontal installation, easy cause reducer heating and oil.

4、establishment of lubricating maintenance system. According to the lubrication work" Five ”principle to the reducer maintenance, do each and a reducer are responsible for regular inspections, found that rising temperatures significantly, over 40。C or temperature exceed 80。C, oil quality decline or oil found in more copper and to produce abnormal noise and other phenomena, should immediately stop using the, timely maintenance, troubleshooting, replacement of lubricating oil. Come on, should pay attention to oil, ensure the reducer to get the correct lubrication.
