Characteristics and manufacturing process of tire coupling

Relying on technological innovation, our factory vigorously improves the modernization level of my country's chemical, mining, non-ferrous metal machinery and equipment, and has developed new varieties of new tire couplings.

The common points and differences of the two categories of tire couplings. Tire couplings are divided into two categories: convex and concave. The convex is divided into three types: integral with frame, integral without bone and radial incision. Kind.Their common feature is that the tire ring is bolted to connect the two halves of the coupling to realize the connection of the two shafts.The inner side of the tire ring is bonded to the steel frame by a vulcanization method, and the bolt holes on the frame are welded with nuts.When assembling, bolts are used to connect the flanges of the two coupling halves. The friction force generated between the tire and the flange end faces by tightening the bolts is used to transmit torque. The torsional shear deformation of the tire ring occurs when the tire ring is working, so the tire coupling It has high elasticity, the ability to compensate the relative displacement of the two shafts is large, and it has good damping, and the structure is simple, does not require lubrication, and is relatively convenient for assembly and disassembly and maintenance.The disadvantage is that the bearing capacity is not high and the external dimension is large. As the relative torsion angle of the two shafts increases, the tire shape is twisted, and the axial dimension is slightly reduced, which will generate a large additional axial force on the two shafts. Increase the bearing load and reduce the life.When the tire coupling is running at high speed, the centrifugal force of the outer edge of the tire expands outward, which will further increase the additional axial force.Therefore, when installing the coupling, measures should be taken to make the direction of the stress in the tire opposite to the direction of the stress generated during work to offset part of the additional axial force and achieve the working conditions of the coupling and the two bearings.

In recent years, with the modernization of my country's chemical, mining, non-ferrous metal and other machinery and equipment, the requirements for improving the performance of the coupling have become higher and higher, especially for the poor operating conditions of the mechanical equipment, the high elastic coupling It has become the focus of many companies.In this regard, our factory makes full use of the existing characteristics of rubber tires and develops new varieties of new tire couplings through process design.This product has good shock absorption and cushioning performance, which solves the cushioning effect that cannot be achieved by general couplings.
