Slewing Bearing for Stacker-reclaimer

Bucket wheel stacking and collecting machine, refers to a large dry bulk storage yard can both stacking and collecting continuous transmission of efficient loading and unloading machinery. It is composed of the belt conveying arm which can pitch and swing horizontally and the bucket wheel, the frame and the running mechanism at the front. The belt can run in both ways. When taking the material, the bucket wheel takes the material and sends it out through the conveying arm. The use of continuous bucket wheel material, with the belt conveyor on the machine continuous stacking rail loading and unloading machinery. It is a special machine for bulk materials (bulk materials) storage yard, which is evolved on the basis of bucket wheel excavator. It can be used as a storage yard transportation mechanized system with unloading (ship) machine, belt conveyor and loading (car) unit. The production capacity can reach more than 10,000 tons per hour. The operation of bucket wheel stacker and retake machine has strong regularity and is easy to realize automation. The control mode includes manual, semi-automatic and automatic. The boom type bucket wheel stacker is composed of bucket wheel mechanism, rotary mechanism, belt conveyor, tail car, pitching and running mechanism. The lifting slewing mechanism is composed of slewing support and driving device to make the boom turn around. In order to ensure that the bucket shovel can be filled when the boom is at any position, the rotation speed is required to realize automatic adjustment within the range of 0.01 ~ 0.2 RPM according to certain rules need use dc motor or hydraulic drive mostly.
