Quick connecting ball pair type coupler

Abstract

The invention discloses a quick connecting ball pair type coupler which comprises an input shaft flange plate, an output shaft flange plate and a connector, wherein the connector comprises a core shaft, a rubber elastomer is arranged at one end of the core shaft in a wrapped manner, metal blocks are uniformly arranged on an outer circumferential surface of the rubber elastomer, the core shaft, the rubber elastomer and the metal blocks are adhered to form an integrated structure, a boss is arranged on the outer circumferential surface at the other end of the core shaft, a jacket is provided with a retainer which is provided with a barb, a spring is fixedly arranged on the end of the retainer, which is close to the barb, a group of circular holes are uniformly arranged in the end of the retainer, which is away from the barb, along a circumferential direction, steel balls are arranged in the circular holes, the end of the connector, which is provided with the rubber elastomer, is arranged in a blind hole of the input shaft flange plate, and the other end of the connector is arranged in a through hole of the output shaft flange plate. When the quick connecting ball pair type coupler disclosed by the invention is adopted, two shafts can be coupled and disassembled quickly and conveniently, and rotation errors are reduced to a certain extent; and moreover, the quick connecting ball pair type coupler has the advantages of low energy consumption, safety, reliability, compact structure and high power.

Description

technical field [0001] The invention relates to a transmission device, in particular to a coupling. Background technique [0002] Under normal working conditions, after a long period of use, ordinary rubber couplings are prone to elastic fatigue damage of the rubber, the torsional vibration strength of the elastic body is reduced, and the torsional torque is reduced, which leads to the failure of the elastic body and cannot compensate for the shaft transmission. The misalignment error generated during the installation and operation of the mechanism; the drum-shaped gear coupling has the disadvantages of high process requirements, high vibration noise, poor economy and pollution of the surrounding environment; The load needs to be used in pairs during installation, the axial distance is long, the volume is large, and the transmission error is large.

Problems solved by technology

[0002] Under normal working conditions, after a long period of use, ordinary rubber couplings are prone to elastic fatigue damage of the rubber, the torsional vibration strength of the elastic body is reduced, and the torsional torque is reduced, which leads to the failure of the elastic body and cannot compensate for the shaft transmission. The misalignment error generated during the installation and operation of the mechanism; the drum-shaped gear coupling has the disadvantages of high process requirements, high vibration noise, poor economy and pollution of the surrounding environment; The load needs to be used in pairs during installation, the axial distance is long, the volume is huge, and the error of the transmission is large at the same time

[0003] Most of the coupling halves are connected by bolts and nuts. Special tools are required for installation and disassembly, which is time-consuming, labor-intensive, inefficient and economical.
