Description

Easy-to-dismount clamping coupling

Technical Field

The utility model relates to a shaft coupling, concretely relates to readily removable formula double-layered shell shaft coupling.

Background

The coupling is also called coupling, and is used for firmly connecting a driving shaft and a driven shaft in different mechanisms to rotate together and transmitting mechanical components of movement and torque. Sometimes also to couple the shaft with other parts (e.g. gears, pulleys, etc.). Usually, the two halves are combined and fastened to the two shaft ends by a key or a tight fit, and then the two halves are connected in a certain way. The coupling can compensate the offset (including axial offset, radial offset, angular offset or comprehensive offset) between two shafts caused by inaccurate manufacture and installation, deformation or thermal expansion in work and the like, and can alleviate impact and absorb vibration. Sometimes it is used as a safety device to prevent the coupled machine parts from bearing excessive load, and it plays the role of overload protection. The double-shaft coupling is characterized in that two double-shaft couplings are axially split and clamped by bolts, torque is transmitted by friction force between the surfaces of the two half couplings, and a flat key is used for auxiliary coupling. The existing shell-clamping type coupler is not easy to install, the coupler with the hook is high in processing difficulty, and the coupler with the hook is easy to fall off when in use.
