Stress and deformation analysis of roller tube and bearing seat
Clicks:16713 Date:4-14
Roller is an important component of the belt conveyor, which comprises a pipe body, a bearing seat and a roller shaft, bearing mainly plays the role of transport of materials, more than 70% of the resistance under the transport process, is the largest amount of belt conveyor, the replacement of the highest frequency component. In the process of conveying pipe, both bearing body, may cause large deformation, causing large roller radial runout, causing the vibration conveyor and conveyor belt on the vibration, vibration stability seriously affect the service life of the roller and the. Therefore, the structure of the roller tube body and the bearing seat is very important to the roller and the belt conveyor.
(1) tube body
The tube body is a thin wall part, which can produce local deformation and bending deformation under the action of local load. In this way, the tube body rotates, the eccentric force will produce, caused by the vibrating pipe, thereby causing vibration, transverse vibration of conveyor belt and conveyor, affect the service life of the roller, especially in high speed belt conveyor, the harm is more obvious.
(2) bearing seat
Bearing seat also belongs to thin-walled parts, if too large deformation. It will directly lead to the increase of radial runout of the pipe body, which will affect the vibration stability of the whole machine and the service life of the roller.
