Causes and treatment of unstable transmission of planetary reducer

When we use the planetary reducer, the problem of noise will occur if we use it too much. If we want to know the cause, we also need to know the basic structure of the reducer. Planetary reducer is composed of worm gear, worm, cast steel casing, plane pressure bearing, taper bearing and oil seal. The worm of planetary reducer is also called curved surface cylindrical worm, in which the tooth surface is generally circular arc concave. The uneven split of the worm and the noise at slow speed are all caused by the quality problem of the bearing. Then how to solve the problems of jitter, noise, excessive temperature rise and jamming in the lifting transmission process of planetary reducer.
1、 The jitter of the reducer after additional load during use is caused by the uneven pitch of the lead screw, the uneven split of the worm, the unqualified quality of the plane pressure bearing and taper bearing, the tight fit between the upper and lower sheaths of the lead screw, and the non concentricity of the installation.
2、 The reason for the noise during the operation of the reducer is the uneven split of the multi head worm of the fast planetary reducer. The reason for the noise at a slow speed is the quality problem of the bearing.
3、 The maximum temperature of the reducer under normal working conditions shall not exceed 45 ℃. In case of high temperature, the machine inspection shall be stopped immediately. Generally, the reason for this problem is that the lead screw elevator of this tonnage is too small and overloaded, or the high temperature occurs when the worm and worm gear end cover are pressed too tightly, The input speed is not excluded. The worm gear lead screw elevator is grease lubricated. The maximum speed of the worm shaft of the lead screw elevator shall not exceed 1000min / s. if the input speed is too high, it will also be high and stuck. The treatment method for high temperature is to reduce the input speed, check whether the embedding fit of the gland is too tight and whether the lead screw elevator is short of oil
The above is the reason and treatment method for the unstable transmission of planetary reducer.
