Abstract
The utility model discloses a moment-limiting friction type coupler which is suitable for a prime mover for driving a working machine to start. The utility model comprises a friction block, a friction block arm, a machine core and a machine core groove. The utility model is characterized in that a tension spring is arranged at the lower end of the friction block arm in the machine core groove. The utility model has the advantages that when a prime mover is started to drive a working machine to rotate, the impact force to the working machine is small, and the working machine can soft start. The utility model also has the inching function.
Description
The utility model relates to the transmission device that connects between a kind of prime mover and the working machine, is suitable for using when prime mover drives the working machine starting.
China Patent No. is 93218731.5 " electricity-saving protection shaft coupling "; it discloses the transmission device between a kind of prime mover and the working machine, and it is to make the working machine starting by the frictional force that the brake pad on prime mover produces, it simple in structure; starting current is little, long service life.But it also has deficiency: soft starting characteristic is poor, and is big to the impact force of working machine, and do not have the crawl function.
The utility model is intended to provide a kind of limit square friction coupler, and it is when state of rest, and brake pad is pushed the coupling drive wheel to, and less frictional force is arranged, and is soft start during starting, reduces the impact to working machine, also can produce the crawl effect.
Task of the present utility model is achieved in that limit square friction coupler includes brake pad, brake pad arm, movement, movement groove, and it is characterized in that: there is tensile spring the lower end of brake pad arm in the movement groove.
The utility model is because when state of rest, brake pad is subjected to the thrust of tensile spring, has relied on the coupling drive wheel, less frictional force is arranged, so when prime mover machine that starts to work rotates, little to the impact force of working machine, soft start reposefully, and also have the crawl function.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing an embodiment of the present utility model is described in further detail.
Several movement grooves 4 are arranged on movement 5, and brake pad 1 is fixed on the brake pad arm 2, and brake pad arm 2 can insert in the movement groove 4, and tensile spring 3 is installed in its underpart, and brake pad arm 2 can radially be stretched in movement groove 4.When remaining static, brake pad 1 is pressed to the coupling drive wheel under the effect of tensile spring 3, less friction is arranged.When prime mover started, brake pad 1 was subjected to action of centrifugal force, and the pressure that the coupling drive wheel is produced increases gradually, when reaching certain pressure, and the working machine starting.This kind starting is very steady, and is little to the impact force of working machine, is the meaning soft start.When working machine stopped, prime mover also recovered state of rest, and brake pad 1 is still pressed to the coupling drive wheel under the effect of tensile spring, less frictional force is arranged.
