Rigidity-adjustable compact coupling

Abstract

The rigidity-adjustable compact type coupler comprises a clamping ring connected with a driving shaft into a whole, and a ring sleeve is arranged on the clamping ring; the supporting body is arranged on the driving shaft and connected with an annular flange through a torque limiter; and the pre-compression eccentric split type lining is connected with the clamping ring and the supporting body. The pre-compression eccentric split type bushing is adopted, axial pre-compression of the rubber bushing is achieved through the bolt, the elastic body is expanded, after the bolt is unloaded, the size of the elastic body is reduced, the elastic body is easy to disassemble, and maintenance convenience of the elastic body is achieved.

Description

technical field [0001] The invention relates to a compact shaft coupling with adjustable stiffness, which belongs to the field of wind power generation. Background technique [0002] The traditional coupling structure is relatively complex, the installation space is large, disassembly and maintenance are difficult, the cost is high, and the stiffness cannot be directly adjusted on the equipment. Therefore, a compact coupling with small volume, convenient disassembly, adjustable stiffness and easy maintenance is designed. Type couplings have become an urgent problem to be solved in the field of wind power. [0003] Existing compact couplings generally use bushings and a simple mandrel plus elastomer structure. If you want to adjust the stiffness during product use and maintenance, you can only achieve it by replacing the elastomer. The stiffness is directly adjusted on the equipment, and the connection method of the brake disc has the disadvantage of a long transmission chai...

Problems solved by technology

[0002] The structure of the traditional coupling is relatively complex, the installation space is large, the disassembly and maintenance are difficult, the cost is high, and the stiffness cannot be directly adjusted on the equipment. Type coupling has become an urgent problem to be solved in the field of wind power

[0003] Existing compact couplings generally use bushings and a simple mandrel plus elastomer structure. If you want to adjust the stiffness during product use and maintenance, you can only achieve it by replacing the elastomer. The stiffness is directly adjusted on the equipment, and the connection method of the brake disc has the disadvantage of a long transmission chain

[0004] Generally speaking, the parts that realize axial compensation include rubber parts, but the stiffness of the rubber parts in the traditional structure cannot be directly adjusted on the equipment, and the rubber parts are prone to creep and aging during a long period of use, and the stiffness decreases. Small, thus affecting the overall stiffness of the coupling

The traditional compact coupling has the problem of inconvenient maintenance
