Thin-walled deep groove ball bearings use roller made of special polymer materials, has the advantages of light weight, small rotational inertia characteristics. Thin-walled deep groove ball bearings installed below the receive segments in conveyor, conveyor belt material to reduce the impact of falling material. Because of the smaller friction between the bearing thin-walled deep groove ball and ring, so better able to extend the service life of conveyor belt. Here we describe specific protective effect of thin-walled deep groove ball bearing play:
(1) the temperature protection of linear plain bearings thin
Belt conveyor roller and bearing friction causes the temperature exceeds the limit, the detection device is installed close to the drum emit ultra-high temperature signal, the receiver receives the signal, the 3S delay, make the execution part action to cut off the motor power supply, automatic stop running conveyor thin-walled deep groove ball bearings, plays the temperature protection function.
(2) speed protection of deep groove ball bearing thin
When the conveyor agricultural bearings failure occurred in the process of operation, installation is SG accident sensor on the motivation of magnetic switch can not be closed or not according to the normal speed closed on the conveyor, the control system will be the inverse time characteristics after a certain delay, speed protection circuit works, make the implementation of part of the action, cut off slewing bearing manufacturer motor power supply, to avoid accident expansion.
