Coupling braking load limiter

Abstract

The invention discloses a coupling braking load limiter, comprising a case, an upper end cover, an upper locating sleeve assembly, a spring stressed plate, a brake spring assembly, a spring seat, a plane bearing, a lower locating sleeve assembly, a semi-active coupler, a friction plate support assembly and a semi-driven coupler assembly. The coupling braking load limiter is characterized in that the case, the upper end cover, the upper locating sleeve assembly, the spring stressed plate, the brake spring assembly, the spring seat, the plane bearing, the lower locating sleeve assembly, the semi-active coupler, the friction plate support assembly and the semi-driven coupler assembly are arrange in order along the direction of axial line, the semi-active coupler drives an induction magnet to induce a proximity switch during overloading, and then a signal is given out to cut off the power of a main motor, thus realizing the function of an overloading protection working machine. When losing power, the energy stored by pressing the brake spring is released immediately to push the semi-active coupler and the friction plate assembly to generate friction with the semi-driven coupler assembly, thereby forming brake moment and realizing braking. The limiter is widely applied to mechanical transmission.

Description

technical field [0001] The invention relates to a coupling brake load limiter. Background technique [0002] The existing shaft coupling only has the function of shaft coupling, which is a device that connects two shafts or shafts and rotating parts to rotate together without disengagement during the process of transmitting motion and power; the existing brake is used for mechanism or machine deceleration A device that stops or stops, and is sometimes used to adjust or limit the movement speed of a mechanism or machine. It is an important part to ensure the safe and normal operation of a mechanism or machine. In terms of performance, there are two categories: rigid couplings and flexible couplings. Although both types of couplings can achieve the effect of coupling transmission, when the machine is overloaded, it will not be protected due to overloading. machine, so it is easy to cause damage to the machine, and it will not brake immediately because the machine stops, which...

Problems solved by technology

In terms of performance, there are two categories: rigid couplings and flexible couplings. Although both types of couplings can achieve the effect of coupling transmission, when the machine is overloaded, it will not be protected due to overloading. machine, so it is easy to cause damage to the machine, and it will not brake immediately because the machine stops, which will easily cause quality and safety problems. Therefore, the existing couplings cannot be directly applied to overload protection and require machine power-off braking at the same time. finished working environment

Similarly, the existing brakes only have a braking function, and the load limiter has only a single load limiting function, but there is no such thing as a coupling brake load limiter with both coupling braking and load limiting functions.
