First of all, after the gear is under load and the power is transmitted, the mesh will be deformed flexibly, the load becomes bigger than the no-load deformation, and the impact force on the mesh will be very large, which will cause a lot of noise.
Secondly, the gear machining accuracy and rigidity also generate noise. For example, the gear machining accuracy is low, the error is large, the meshing impact is large, the gear rigidity will be reduced, and a large elastic force will be generated after the force, resulting in a large noise .
Noise reduction measures for electric hoists: When selecting equipment, try to choose better motors. This will not only reduce the noise of the gear but also the noise of the motor.
Increasing the gear rigidity can reduce its elastic deformation and reduce the impact force, which is an effective way to reduce noise.
Although the motor is not the main noise source of the equipment, it does appear noise. When selecting a motor, its noise should be more than five decibels lower than the total noise of the equipment.
The problem of noise involves many factors and is more complicated to solve. If we want to solve the noise, first check whether the equipment is faulty and find out the main cause of the noise, then we can find an effective solution.
