Description

Technical Field

[0001] The present invention relates to the technical field of couplings, and in particular to a coupling, a processing and production equipment and a processing method thereof. Background Art

[0002] In the field of industrial transmission, couplings are key components that connect different shaft systems and transmit torque. The performance of couplings directly affects the stability, reliability and service life of the entire transmission system. Traditional couplings gradually reveal many limitations when facing complex and changeable working conditions.

[0003] On the one hand, during the power transmission process, due to the differences in the starting, running, and braking characteristics of different equipment, impact loads, vibrations, and misalignment between shaft systems often occur. Ordinary couplings are difficult to effectively buffer and absorb these adverse factors, resulting in fatigue damage to themselves and the connected equipment. Frequent maintenance and replacement not only increase production costs, but also cause production interruptions and reduce production efficiency. For example, in some high-speed mechanical equipment, tiny vibrations will accumulate over a long period of time, causing the connection parts of the coupling to become loose and wear more severely, thereby affecting the transmission accuracy and even causing safety accidents.

[0004] On the other hand, the existing coupling processing technology and supporting equipment also have shortcomings. Traditional processing methods mostly rely on manual operation or simple fixtures, and it is difficult to ensure high precision and consistency in key processes such as drilling and grinding of parts. Manual operation is not only labor-intensive and inefficient, but also greatly affected by human factors, and is prone to quality problems such as drilling position deviation, substandard aperture accuracy, and uneven inner diameter grinding. At the same time, there is a lack of integrated processing equipment designed specifically for the structural characteristics of the coupling, the various processing links are not smoothly connected, and the material flow efficiency is low, which further restricts the production efficiency and quality improvement of the coupling.
