In the using process of the chain wheel, due to the change of production functions, more transmission functions are possibly needed, at the moment, a plurality of chain wheels and chains need to be added for matching use, but in the using process of the chain wheel, because the first chain wheel is already installed on a transmission shaft through keys and the like, and then the chain wheel is added, a shaft with a proper number of key grooves needs to be replaced, so that more chain wheels are installed, the working strength of the chain wheel is increased, and the production time of equipment is influenced, therefore, the inventor provides an engineering machinery chain wheel so as to solve the problems.

Disclosure of Invention

The utility model aims to solve the problem that the working strength of the additional chain wheel is high because the number of the key grooves of the transmission shaft for mounting the chain wheel is not corresponding when the chain wheel needs to be added in the using process of the traditional chain wheel.

In order to achieve the above object, a basic scheme of the present invention provides an engineering machinery sprocket, including a sprocket body and an extension sprocket installed at one side of the sprocket body, wherein one side of the sprocket body close to the extension sprocket is provided with a first axial connecting groove and a plurality of first radial limiting grooves located around the first axial connecting groove, one side of the extension sprocket close to the sprocket body is fixedly connected with a connecting convex ring capable of being inserted into the first axial connecting groove and a plurality of limiting connecting blocks capable of being inserted into the first radial limiting grooves, the centers of the sprocket body and the extension sprocket are both provided with shaft holes, and the shaft holes of the sprocket body are provided with key grooves.

The principle and effect of this basic scheme lie in:

1. when a plurality of chain wheels are not needed, the chain can be started to be used only by fitting a key with the key groove of the chain wheel body on the transmission shaft and then fitting the chain with the specification of the chain wheel body.

2. When needs increase chain drive, need not dismantle any sprocket and chain that has installed and put into use, only need take out an extension sprocket, imbed the first axial spread groove of sprocket body with this extension sprocket's connection bulge loop in, the spacing connecting block of extension sprocket simultaneously alright take the place of embedding first radial spacing inslot, then alright install the chain that corresponds on the extension sprocket, when using, because spacing connecting block is restricted in first radial spacing inslot, when carrying out coaxial rotation between sprocket body and the extension sprocket, just can not take place relative slip, this has just accomplished the no dismantlement of chain and has increased.

Compared with the prior art, the utility model can effectively reduce the difficulty in maintaining mechanical engineering, simultaneously reduce the labor intensity of workers, improve the working efficiency, has simple operation and is convenient for popularization and use.

Further, run through on sprocket body and the extension sprocket and open and have a plurality of spacing holes, spacing downthehole can be equipped with spacing connecting rod, and the both ends of spacing connecting rod can be dismantled and be connected with the locking cap that is used for locking sprocket body and extension sprocket. When using, the condition that the extension sprocket takes place the displacement for the sprocket body probably appears, utilizes a plurality of spacing connecting rods and a plurality of locking cap, can lock sprocket body and extension sprocket, just can not discover the condition of relative displacement.

Furthermore, a second axial connecting groove into which the connecting convex ring can be inserted and a plurality of second radial limiting grooves into which the connecting blocks can be inserted at positions are formed in one side of the expanding chain wheel, which is far away from the chain wheel body. A plurality of expanding chain wheels are added on the basis of expanding chain wheels so as to adapt to different use requirements.

Further, a plurality of oil grooves are formed in one side, close to the extension chain wheel, of the chain wheel body and in two sides of the extension chain wheel. When the chain wheel is used, the condition that the contact surfaces of the chain wheel body and the extended chain wheel are rusted can be effectively prevented.

Furthermore, the locking cap is in threaded connection with two ends of the limiting connecting rod. The locking cap is convenient to disassemble.

Furthermore, one side of the locking cap, which is far away from the limiting connecting rod, is provided with an inner hexagonal limiting groove. The locking cap is convenient to mount and dismount.

Furthermore, the extension chain wheel, the connecting convex ring and the limiting connecting block are integrally formed. The use stability of the expanding chain wheel is improved.
