What should we pay attention to when using Conveyor roller?
Clicks:2203 Date:11-27
Conveyor roller is mainly subjected to radial load and radial load and axial load simultaneously. The contact angle is zero when it is only subjected to radial load. When Conveyor roller has larger radial clearance, it has the performance of angular contact bearing, and can bear larger axial load. The friction coefficient of Conveyor roller is very small, and the limit speed is also high, especially in the condition of high axial load, Conveyor roller is more advantageous than thrust ball bearing.
1, axis and Conveyor roller room tolerance selection and control: Conveyor roller press into Conveyor roller should be flexible rotation, no sense of blocking. To remind people that if the obvious rotation is not flexible, it shows that the size of the shaft is too large, the tolerance should be lowered. If the Conveyor roller is pressed into the shaft, there is obvious rustling sensation by hand rotation, it may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, in the control of the shaft and Conveyor roller room tolerance, but also to control the roundness, at present, many domestic manufacturers only tolerance control, there is no control of roundness.
2, Conveyor roller assembly method: because Conveyor roller is a high-precision product, such as improper assembly, it is easy to damage the Conveyor roller channel, resulting in Conveyor roller damage. Conveyor roller in the assembly should have a dedicated mold, can not beat, in pressing axis only small force, only large force pressing circle. When assembling, the air pressure or hydraulic pressure should be adopted. The upper and lower die should be outside the horizontal state during the press mounting. If there is an inclination, the Conveyor roller channel will be damaged due to the force, so that the Conveyor roller will produce the sound.
3, assembly of foreign body prevention: Conveyor roller in the dynamic balance when installed on the rotor, it is easy to dynamic balance when the iron chip into the Conveyor roller internal, so it is best to install Conveyor roller before dynamic balance. Xiao Bian also learned that some manufacturers for ease of assembly, assembly of some oil or grease lubrication effect in Conveyor roller indoor painted, but often the operator is difficult to control, if the oil or grease in the Conveyor roller interior accumulates more, in Conveyor roller along the axis rotates easily into the Conveyor inside roller. Conveyor roller room is best not to oil or grease, if not coated, must be controlled, not in the Conveyor roller indoor accumulation.
4, paint rust prevention: paint rust is characterized by multiple in sealed motor, motor assembly sound is very good, but in the warehouse for some time, the motor abnormal sound is very big, remove Conveyor roller has serious rust phenomenon. Before many manufacturers will consider the problem of Conveyor roller, through our continuous publicity, now the motor factory has been aware of the main problem of insulating paint. The problem is mainly due to the corrosive substances formed by the volatile substances of insulating paint, which form corrosive substances under certain temperature and humidity, and cause Conveyor roller damage after Conveyor roller channel corrosion. The problem can only be selected by the good insulating paint, and after drying for a period of time after the assembly.
The life of Conveyor roller is closely related to the manufacture, assembly and use, and must be done in every link in order to make the Conveyor roller in the best running state, so as to prolong the service life of Conveyor roller.
