Liaocheng slewing bearing 3... Quotation - ! /, -, Selection of bearing models: Bearing models are generally selected by the user's technical staff based on the use conditions and load-bearing load of the supporting products. Business personnel mainly understand whether the actual load of the user is consistent with the selected bearing. If the bearing does not meet the usage requirements, the customer should be advised to change the model as soon as possible. However, unless there is a special product, there will generally be no problem in selecting the model.
< / , -: - ! / , - Selection of bearing clearance: When purchasing bearings, users generally only tell them what model and grade they are in, and rarely put forward requirements for bearing clearance. Business personnel must Ask about the usage conditions of the bearing, including the bearing's speed, temperature, and fitting tolerances, which are directly related to the selection of imported bearing clearance. Generally speaking, most motors with speeds below 3 rpm use clearance. For example, high-temperature and high-speed motors require relatively large clearances. After assembly, the bearing clearance will be reduced due to the enlargement of the inner hole and the shrinkage of the outer circle. The reduction in clearance is the amount of interference (except for the bearing chamber made of aluminum). For example, the clearance before assembly of the bearing is ., and the interference amount during assembly is . Then the clearance after assembly of the bearing is . In theory, the noise and life of the bearing reach the optimal state when there is zero clearance. However, in actual operation, considering the temperature rise and other issues, the clearance of the bearing after assembly is better.
< / , -: - ! / , -: Selection of grease: The selection of grease is generally based on the bearing's rotation speed, temperature resistance, noise requirements and starting torque. Business personnel are required to select various types of grease. The properties of grease are well understood.
< / , -: - ! / , -. Selection of bearing seal type: The lubrication of imported bearings can be divided into oil lubrication and grease lubrication. Oil-lubricated bearings generally use form bearings, while grease-lubricated bearings generally use dust caps or rubber seals for sealing. The dust cover is suitable for parts with high temperature or good use environment. The seals are divided into contact seals and non-contact seals. The contact seals have good dustproof performance but large starting torque. The non-contact seals have small starting torque but good sealing performance. Not as good as contact.
