As far as the types of mechanical parts are concerned, the cycloidal pinwheel reducer has the most typical structure, contains the most types of mechanical parts, and is widely used in today's production and life.
Assembly Method and Suggestion for Parts of Cycloidal Pinwheel Reducer
1. Bearing and gear assembly
In the cycloid reducer, there is generally an interference fit between the bearing and the shaft, and between the gear and the shaft.In fact, during assembly, shafts, bearings and gears are often placed in an oil bath to be heated.They can be assembled in this state due to heat deformation and softening.This is the assembly method of interference fit.Putting the parts into the oil is mainly to make the parts evenly heated and deformed.However, since the oil in the oil pool needs to be continuously heated, a large amount of energy needs to be consumed.And, the volatilization of oil product also has very big loss.At present, natural gas is generally used for local dynamic heating in factories.Although this heating method does not use oil and has a good heating effect, it has low energy consumption, short time and low cost.
2. Bearing cover assembly
Due to the different structure of the bearing end cover.Identify the different assembly sequences of the bearing end shields during assembly.Generally, the embedded bearing end cover is installed before the box is closed, and the flange bearing end cover is installed after the box is closed.However, in the actual assembly process, the lower shell of the flange bearing end cover is assembled first (but not tightened), then the shell is closed, and the bearing end cover is connected to the upper shell with bolts.According to the assembly principle, this is not conducive to the control of the overall position of the bearing end cover and the adjustment of the clearance.However, due to the low precision requirements of the cycloid reducer, this also limits the development of assembly technology to a certain extent.
