Planetary gearbox is composed of worm wheel, worm rod, cast steel case, flat pressure bearing, taper bearing and oil seal, and its planetary reducer worm is also known as curved cylindrical worm in which the flank is generally curved concave.
Jitter, noise, excessive temperature rise and stuck problems during planetary gearbox lift drive:
1, the use of the gearbox in the process of noise causes and treatment methods?
A: The reason for the noise in the operation of the worm reducer is the uneven distribution of the multi-head worm of the fast planetary reducer, and the reason for the slow noise is the quality problem of the bearings.
2, the gearbox appears too high temperature rise and the cause of stuck and treatment methods?
A: The maximum temperature in the normal working condition of the reducer should not exceed 45 degrees Celsius, if the high temperature should immediately stop the machine inspection, the general cause of this problem is the selection of this tonnage of the reducer is too small overload phenomenon, or the worm and the end cover of the worm wheel with the high temperature situation, input speed is not excluded in the The outer worm wheel reducer is butter lubricated, the maximum speed of the worm shaft should not exceed 1000min/s, such as the input speed is too high and stuck, the high temperature treatment method is to reduce the input speed, check whether the embedded fit of the pressure cap is too tight and whether the planetary deceleration is short of oil.
3, the gearbox in the normal use of the jitter causes and treatment methods?
A: The reasons for the jitter of the planetary gearbox after the additional load during use are uneven screw pitch, uneven snail split, uneven plane pressure bearings and taper bearing quality, tight upper and lower sheaths of the screw, and different heart problems installed.
