The biggest difference between the design of a general-purpose reducer and an ordinary reducer is that the former is suitable for various industries, but the acceleration can only be designed according to specific working conditions. When choosing a reducer, users need to think differently according to their own requirements. Correction coefficient, the factory should select the motor power (not t
There are two main types of noise produced by the reducer: one is due to loose joints between parts, or the sound of parts is broken. This type of sound is mainly caused by abnormal friction and impact between parts. The sound is clearer, and the second is due to the abnormality of the rolling bearing and the abnormality of the gear teeth. For example, if the backlash is too small or too large, th
The temperature rise of the reducer should be measured in a room that is not affected by the external temperature. The indoor ambient temperature should be within the range of 5~40°C. The indoor air should circulate freely, and forced circulation is not allowed. 1. Environmental conditions 1. The temperature rise of the planetary reducer should be measured in a room that is not affected by the ext
Selection of grease When selecting grease according to the bearing load of the planetary reducer, grease with a small needle penetration should be selected for heavy loads. When working under high pressure, in addition to small penetration, it also needs to have high oil film strength and extreme pressure performance. When selecting grease according to environmental conditions, calcium-based greas
Due to the large carbon equivalent of No. 45 steel, the hardening tendency of the heat-affected zone is relatively large during welding, and cold cracks are prone to occur, and the welding amount of the shaft is large, so there is inevitably a large welding deformation and welding stress. In order to reduce welding deformation and improve weld quality, preheating measures before welding are taken,
How to deal with the noise problem of planetary reducers
Introduction to the problems and solutions encountered in the use of planetary reducers
A reducer is a working transmission mechanism that needs to transmit torque to the shaft and bearings. In a planetary reducer, the bearings can serve as a support between the rotation of the gear shaft or connecting rod. Therefore, the transmission efficiency and quality of the reducer are directly related to the bearings, and the sliding quality and lifespan of the bearings will affect the overal
