Zhengzhou Mining Equipment Co., Ltd. with the hope mill equipped with rubber block coupling, in addition to compensation for the relative displacement of the drive shaft, reducing coupling installed on the accuracy requirements, but more important to be able to ease the impact of changes in shafting natural frequency, to avoid the risk of severe vibration. But in the actual production, due to the use, maintenance, improper repair, often coupling rubber blocks and the elastic ring frequently damaged. Rubber block rubber couplings consist of several separate blocks, rectangular blocks of compressed plastic extrusion and by large carrying capacity, but poor flexibility. When the plastic deformation of the block, reducing the gap filled with radial clearance or rubber components, rigid surge, requiring frequent replacement of failed plastic blocks. 1) plastic blocks (plastic bricks) for emergency repair of plastic blocks (plastic bricks) emergency replacement, available scrap conveyor belt and cut the same size piece of plastic (plastic bricks) rectangular, added together, replace plastic bricks. To enhance its strength, where you can join a 3mm thick steel plate. When disassembly or replacement of plastic blocks need to move axially coupling halves, due to space limitations knot cabinet, making assembly difficult, especially with the hole after Zou is repeated disassembly and assembly, casing wear deformation, resulting in Casing shear strength decreases fracture, and remove the difficulty. For this purpose, can be taken to cancel the casing, coupling bolts to increase the diameter of the way. Maintenance, unscrew the bolt long, you can replace the plastic blocks. Zhengzhou, with the hope Mining Equipment Co., Ltd. is specialized in the production of sand and gravel production line, stone production line, mineral materials and production equipment line of professional accessories factory.
