Description

Torque limiting coupler

Technical Field

The utility model relates to the technical field of couplings in mechanical transmission devices, in particular to a torque limiting coupling.

Background

A coupling is a mechanical part for coupling two shafts (a driving shaft and a driven shaft) in different mechanisms to rotate together to transmit torque. In the high-speed and heavy-load power transmission, some couplings have the functions of buffering, damping and improving the dynamic performance of a shaft system. The variety of couplings on the market is wide, with no loss of couplings having torque limiter functionality. The torque limiting coupling is a device for transmitting motion and power between a shaft and a rotating member, and can also play a role of overload protection relative to a common coupling, and separate the shaft from the rotating member when a driving element is overloaded.

The patent number CN201821727944.9 discloses a torque limiting coupler, which comprises a motor and a coupler frame, wherein a first bearing and a second bearing are arranged on the coupler frame, a shaft sleeve is inserted in the first bearing, one end of the shaft sleeve is fixedly connected with an output shaft of the motor, the other end of the shaft sleeve is inserted and provided with a torque limiting shaft, the other end of the torque limiting shaft penetrates through the second bearing and then stretches out of the coupler frame, a cover plate is sleeved on the torque limiting shaft, the cover plate is in contact connection with an outer ring of the second bearing, and a torque adjusting mechanism for controlling torque is sleeved on the outer wall of the torque limiting shaft between the second bearing and the shaft sleeve. The utility model completes the power transmission from the driving shaft to the rotating body with overload protection by a smaller size and a simple structure, realizes the application on small equipment, and has more convenient installation and adjustment and lower production and manufacturing cost.

When the torque limiting coupler is used, the steel balls move back and forth in the mounting grooves to control power transmission, but the steel column mounting grooves roll back and forth to generate larger abrasion, so that the shaft sleeves on the two sides are easy to damage.
