Abstract
The utility model relates to a transmission device of a scraper conveyor for a coal mine, in particular to a chain wheel device used in a chain wheel shaft assembly on the scraper conveyor, aiming at providing a wear-resisting chain wheel with simple structure and low cost. The wear-resisting chain wheel comprises chain teeth. Each chain tooth is provided with a tooth chain cavity. The position on each tooth chain cavity, which is contacted with a chain, is covered by a wear-resisting layer. With the adoption of the structure, the wear resistance of the tooth chain cavities of the chain wheel is greatly improved and the service life of the chain wheel is prolonged.
Description
Technical field
The utility model relates to a kind of colliery with the driving device on the slat conveyer, particularly relates to a kind of wear-resisting sprocket wheel.
Background technology
Continuous development along with coal mining industry, performance requriements to the slat conveyer that uses on the down-hole coal excavation driving surface is also improving constantly, the sprocket shaft group is the critical component on the slat conveyer, sprocket wheel then is the strength member on the sprocket shaft group, the resistance to abrasion of tooth portion chain nest is for having crucial effects in service life of sprocket wheel on the sprocket wheel, present domestic most of manufacturer is in the processing and manufacturing process of sprocket wheel, it generally only is direct heat-treatment quenching behind processing chaining nest on the sprocket parent material, yet the sprocket wheel that this mode is produced, the resistance to abrasion of its tooth portion chain nest is subjected to the limitation of parent material and can not reaches higher, thereby has influenced the service life of whole sprocket wheel.
The utility model content
The technical problems to be solved in the utility model provides a kind of wear resisting property and obtains important breakthrough thereby wear-resisting sprocket wheel that can long-term use, has reduced the replacing number of times of sprocket wheel, has reduced underground labour's labour intensity, has improved production efficiency.
The wear-resisting sprocket wheel of the utility model comprises sprocket, and sprocket is provided with tooth portion chain nest, and the contact site with chain on the described tooth portion chain nest is coated with wearing layer.
The wear-resisting sprocket wheel of the utility model, wherein said wearing layer are high chrome molybdenum material.
The beneficial effect of the wear-resisting sprocket wheel of the utility model is: after covering wearing layer with the contact site of chain on the tooth portion chain nest, the wear resisting property of sprocket tooth part chain nest improves greatly, has prolonged the service life of whole sprocket wheel.
Below in conjunction with accompanying drawing Wearing-resistant chain wheel of the present utility model is described further.
Description of drawings
Fig. 1 looks cutaway view for the master of the wear-resisting sprocket wheel of the utility model;
Fig. 2 is the birds-eye view of the wear-resisting sprocket wheel of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the wear-resisting sprocket wheel of the utility model comprises sprocket 1, and sprocket 1 is provided with tooth portion chain nest 2, and the contact site with chain 3 on the tooth portion chain nest 2 is coated with high chrome molybdenum material wear-resistant layer.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
Claims (2)
1. a wear-resisting sprocket wheel comprises sprocket (1), and sprocket (1) is provided with tooth portion chain nest (2), it is characterized in that: described tooth portion's chain nest (2) is gone up and the contact site of chain (3) is coated with wearing layer.
2. wear-resisting sprocket wheel according to claim 1 is characterized in that: described wearing layer is high chrome molybdenum material.
