Description

Anti-off-chain sprocket for die-forged fork type chain

technical field

The invention belongs to the technical field of chain equipment, in particular to an anti-off-chain sprocket for die-forged fork type chains.

Background technique

A sprocket is a wheel with cog-type sprockets designed to engage precisely pitched blocks on a link or cable, a solid or spoked gear that engages a (roller) chain for transmission sports.

The traditional die-forged fork-type chain sprocket is not equipped with an anti-off-chain structure, and there are no good protective measures for the phenomenon of off-chain during the operation of the chain.

Contents of the invention

(1) Solved technical problems

Aiming at the deficiencies of the prior art, the present invention provides an anti-off-chain sprocket for a die-forged fork chain, which solves the problem that the traditional sprocket is not equipped with an anti-off-chain structure and the chain is off-chain during the operation of the chain. Phenomena without good protective measures.

(2) Technical solution

In order to achieve the above objectives, the present invention is achieved through the following technical proposals: an anti-off-chain sprocket for die-forged fork-type chains, including a sprocket body, and both front and rear side walls of the sprocket body are provided with limit mechanisms, so The limiting mechanism includes a stabilizing guide sleeve and an anti-off-chain limiting shaft. The number of the stabilizing guiding sleeve and the anti-off-chain limiting shaft in a single limiting mechanism is 3, and the two sets of increasing The stabilizing guide sleeve is fixedly connected to the front and rear side walls of the sprocket body, and a single set of the stabilizing guide sleeves is distributed in a circular array. One end of the anti-off-chain limiting shaft extends to the outside of the sprocket hole, and the other end of the anti-off-chain limiting shaft extends to the edge of the sprocket.

Preferably, both ends of the anti-off-chain limiting shaft are arc-shaped.

Preferably, a set of transmission balls is locked in rotation on one end side wall of the anti-off chain limit shaft located on the outer wall of the sprocket hole, and the transmission balls are distributed in a line.

Preferably, two pressing plates are arranged inside the stabilizing guide sleeve, and a plurality of pressing springs are fixedly connected to the side walls of the two pressing plates close to the stabilizing guiding sleeve, and the pressing springs The end away from the pressure-applying plate is fixedly connected to the inner side wall of the stabilization guide sleeve, and the side wall of the pressure-applying plate away from the stabilization guide sleeve is rotatably engaged with a plurality of connecting balls.

Preferably, the front and rear side walls of the sprocket body are fixedly connected with closed cover plates, and the outer surface of the closed cover plate is provided with a hole corresponding to the chain-off prevention limit shaft.

Working principle: When in use, insert the sprocket shaft into the sprocket hole. Since the side wall at one end of the anti-off-chain limit shaft is located outside the sprocket hole, a set of transmission balls is locked, and both ends of the anti-off-chain limit shaft are Arc-shaped, so that the sprocket shaft will not be hindered during the insertion process. Due to the insertion of the sprocket shaft, the overall position of the anti-off-chain limit shaft will move outward. The position shaft will limit the chain from both sides, effectively preventing the chain from falling off during operation. When the sprocket is not suitable, pull out the sprocket shaft and reset the anti-disengagement limit shaft, which is convenient for the sprocket to move. Migrating between different working environments, and the limiting method of the pressure spring, the pressure plate and the connecting ball make the movement of the anti-off-chain limit shaft convenient and work stable.

(3) Beneficial effects

The invention provides an anti-off-chain sprocket for a forged fork type chain. Has the following beneficial effects:

1. The die-forged fork chain uses an anti-off-chain sprocket. When the sprocket shaft is inserted, the overall position of the anti-off-chain limit shaft will move outward, and the anti-off-chain limit shaft in the two sets of limit mechanisms will move from The chain is limited on both sides to effectively prevent the chain from falling off during operation.

2. The die-forged fork chain uses an anti-off-chain sprocket. When the sprocket is not suitable, pull out the sprocket shaft and reset the anti-off-chain limit shaft to facilitate the migration of the sprocket between different working environments, and The limiting mode of the pressing spring, the pressing plate and the connecting ball makes the movement of the anti-off-chain limiting shaft convenient and stable in work.
