Reducers are generally used for low speed and high torque transmission equipment, where the power of electric motors, internal combustion engines, or other high-speed operation is reduced by meshing the small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers also have several pairs of gears with the same principle to achieve ideal decelera
How to choose the model of the reducer? How to choose a reducer?
When the reducer takes over, check that the centerline of the motor takeover is the same as the centerline. And install the dial indicator, the rotary reducer takes over a circle, and record the dial indicator at the upper and lower points. (If the reducer is not suitable for rotation, you can attach the magnetic base unit to the motor and rotate the motor shaft. Yes) Calculate the difference betw
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,
