In the working process, the chain drive of the cycloid reducer's chain drive load cycloidal reducer leads to the load, which generates vibration, shock and noise, which directly affects the performance and service life of the chain drive. . In order to obtain a smooth chain drive, the main cause of dynamic load should be analyzed.
The cyclical changes in the angular velocity of the 1 chain and the driven sprocket produce acceleration, which causes additional dynamic loads. The greater the acceleration of the chain, the greater the dynamic load will be.
The vertical sub-speed of the 2 chain movements also changes periodically, and the chain generates vibration, thereby generating additional dynamic loads.
3 When the link enters the sprocket cogging, the link and the gear mesh at a certain relative speed, and the chain and the sprocket are subjected to impact and generate additional dynamic load.
4 If the chain is not tight, the chain is slack, and inertia impact will occur during start-up, braking, reversal, load change, etc., causing the chain drive to generate a large dynamic load.
In summary, in the design of the chain drive, more sprocket teeth and a smaller chain pitch are used. When working, the chain should not be too loose, and the maximum transmission of the chain drive should be limited as much as possible to reduce the dynamic load of the elevator chain drive.
