Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings.

[0008] see figure 1 , the present invention includes a sprocket body 1, on the sprocket body 1 uniformly distributed and fixed sprocket teeth 2 in the shape of concave teeth, positioning pins 3 for positioning the sprocket teeth on the sprocket body.

[0009] The invention adopts the concave tooth type, which has large bearing capacity, high strength and high precision. The biggest feature is to improve the meshing performance of the chain and the dragging sprocket, and it has a strong adaptability to the large deviation of the chain manufacturing. The chain forms a deflection between the dragging sprockets, which can automatically tension the running slag extractor, so there is no need to frequently tension and shorten the chain. The chain runs in the tooth groove of the dragging sprocket, which has good guiding performance and is not easy to drop the chain. Even if...

Abstract

The invention discloses a chain-transmission positioning device. The chain-transmission positioning device comprises a chain wheel body and concave-tooth-shaped chain teeth fixed to the chain wheel body in an evenly distributed mode, and the chain wheel body is further provided with a positioning pin enabling the chain teeth to be positioned on the chain wheel body. The chain-transmission positioning device is easy to assemble, accurate in positioning, uniform in force bearing, stable in transmission, low in noise, high in strength, high in precision and long in service life, and the chain-transmission positioning device can be widely applied to chain-transmission equipment in industries of mines, electric power and ships, and especially applied to submerged chain conveyors in the electricpower equipment industry.

Description

technical field [0001] The invention relates to a chain drive equipment used in mining, electric power and shipbuilding industries, in particular to a chain-moving positioning device. Background technique [0002] The existing drag sprocket generally has no positioning structure, the spacing error of the chain teeth is large, the positioning is inaccurate, the force of the chain transmission is uneven, the transmission is not stable, the transmission error is large, the noise is large, and the service life is short. Contents of the invention [0003] The object of the present invention is to provide a chain-moving positioning device with simple assembly, accurate positioning, uniform force, stable transmission, low noise, high strength, high precision and long service life. [0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: comprising a sprocket body and evenly distributed sprocket teeth fixed on the sprock...
