Integrated assembling free flexible coupling

Abstract

The integrated assembling-free flexible coupling is one cylindrical body including two connecting ends and flexible mechanism in the middle part, and the connecting end has one connecting hole and one slot to divide the connecting hole into two parts. There are one screw hole in the direction perpendicular to the slot and one screw fitting the screw hole. The flexible mechanism is formed with parallel circular sheets connected together. The integrated assembling-free flexible coupling has compact structure, no friction, no need of lubricating, long service life, less influence of environment temperature, easy-to-obtain machining precision, low cost, smooth motion transfer, self regulation of axial error, shock buffering and convenient assembling and disassembling, and is especially suitable for the field with moisture, great impact, frequent starting and frequent rotation direction change.

Description

technical field [0001] The invention belongs to the field of mechanical parts, in particular to an integral assembly-free flexible coupling. Background technique [0002] Couplings are one of the important basic components with a large quantity and a wide range. At present, there are mainly two types of couplings: rigid couplings and elastic couplings. The rigid fixed coupling has a simple structure and low cost, but it lacks the ability to compensate for the relative displacement between the two connected shafts, so it has high requirements for the neutrality of the two shafts. If the relative displacement of the two shafts occurs, it will Additional loads are caused on couplings and bearings, so it is only suitable for occasions where there is no impact and the shaft is well centered. Elastic couplings mainly include elastic sleeve pin couplings, elastic pin couplings, tire couplings and other types. The elastic sleeve pin coupling is easy to manufacture, easy to assemb...

AI Technical Summary

Problems solved by technology

The elastic sleeve pin coupling is easy to manufacture, easy to assemble and disassemble, and low in cost, but the elastic sleeve is easy to wear and has a short life; the elastic pin has a simple structure, is easy to manufacture and install, and has a long life. It is suitable for large axial movement, In the case of forward and reverse rotation or frequent starting and high speed, the working temperature is limited to -20°C-70°C because the nylon pin is sensitive to temperature; the tire coupling can cushion and absorb vibration, and is suitable for wet and dusty applications. , large impact, frequent starting and frequent forward and reverse occasions

At present, these couplings are assembled from multiple parts. Due to factors such as assembly and wear, these couplings have many shortcomings such as short service life and easy wear and tear.
