Abstract

The utility model belongs to the technical field of scraper conveyers and provides a chain wheel used for a scraper conveyer. The chain wheel used for the scraper conveyer comprises a chain wheel body. The chain wheel body is provided with a chain nest. A laser cladding coating layer is arranged on the surface of the chain nest. According to the chain wheel used for the scraper conveyer, due to the fact that the laser cladding coating layer is arranged on the surface of the chain nest, an alloy surface with high performance can be manufactured on the surface of the chain nest on the premise that properties of the chain wheel body are not affected, precious and rare metal materials are saved, cost is reduced, performance, such as abrasion resistance, erosion resistance, heat resistance and oxidation resistance, of the chain nest is enhanced, the service life of the chain wheel is prolonged, maintenance cost under a mine well is reduced, and economic benefit is high.

Description

The sprocket wheel that is used for slat conveyer

Technical field

The utility model belongs to the slat conveyer technical field, relates in particular to a kind of sprocket wheel for slat conveyer.

Background technology

Because service conditions is complicated under the coal mine, environment is abominable, and fully-mechanized mining equipment has been proposed requirements at the higher level, should be wear-resisting, anti-corrosion, heat-resisting, anti-oxidant, reduce again cost, reduce fault, increase the service life.

Slat conveyer is underground coal mine transportation equipment, sprocket wheel is the important drive element of slat conveyer, in sprocket wheel socket and the round-link chain engagement process, bear huge reverse load and additional impact load, therefore sprocket wheel socket wear-resisting, anti-corrosion, heat-resisting, anti-oxidant proposed very high requirement.

Although existing sprocket wheel socket has carried out modified and quenching technical is processed, it is wear-resisting, anti-corrosion, heat-resisting, anti-oxidant to harsh environment under the coal mine or some deficiency.And existing sprocket body chain nest surface is in order to increase wear resisting property build-up wear-resistant layer, the wearing layer of built-up welding and sprocket wheel can not smelting be in the same place, be easy to come off, therefore the life-span of sprocket wheel had a great impact, head it off has just become key.

The utility model content

The purpose of this utility model is to provide a kind of sprocket wheel for slat conveyer, and Chain Wheel of Flight Bar Conveyor is wear-resisting, anti-corrosion, heat-resisting, antioxygenic property is poor to solve, the technical matters that service life is short.

The utility model is achieved in that the sprocket wheel for slat conveyer, comprises sprocket body, has the chain nest on the described sprocket body, and described chain nest surface is provided with laser cladding coating.

As a kind of improvement, described laser cladding coating thickness is 0.2-2mm.

The sprocket wheel that is used for slat conveyer that the utility model provides, because described chain nest surface is provided with laser cladding coating, thereby in the situation of the character that does not affect sprocket body, not only prepare performance-oriented alloy surface on chain nest surface, saved valuable Rare Metals Materials, reduced cost, and wear-resisting, anti-corrosion, heat-resisting, the antioxygenic property of chain nest are strengthened greatly, prolonged the service life of sprocket wheel, reduced the maintenance cost under the coal mine, economic benefit is very high.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A structural representation among Fig. 1;

Fig. 3 is the partial enlarged drawing among Fig. 1;

Among the figure, 1, sprocket body, 2, the chain nest, 3, laser cladding coating.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Shown in Fig. 1, Fig. 2 and Fig. 3 are common, be used for the sprocket wheel of slat conveyer, comprise sprocket body 1, have chain nest 2 on the sprocket body 1, chain nest 2 surfaces are provided with laser cladding coating 3.

Laser cladding coating 3 thickness are 0.2-2mm.

Sprocket body 1 is used forging blank, adopts numerical control electric spark Fabricating machinery machining chain form of gear tooth, and numerical control machining center mills out chain nest 2.Numerical control electric spark processing has guaranteed that the position degree of tooth evenly distributes on sprocket body 1, the numerical control milling machining center has guaranteed the size of chain nest 2, so that sprocket wheel cooperates precision with chain, " stinging chain " phenomenon can not occur, has prolonged the service life of sprocket wheel, chain.

Sprocket body 1 toothed surfaces is at first carried out modified and is quenched, and adopts the sprocket wheel special quenching machine to quench, and Industrial Computer Control guarantees that heavy sprocket wheel depth of hardening reaches more than the 10mm, and middle-size and small-size sprocket wheel depth of hardening reaches more than the 8mm.Finish the rear special material of coating 0.2-2mm on chain nest 2 surfaces that quenches at it, such as carborundum, make it to melt simultaneously with the material on chain nest 2 surfaces through laser irradiation, and form behind the rapid solidification dilutability extremely low and with the laser cladding coating 3 of chain nest 2 surface material metallurgical binding, thereby significantly improve wear-resisting, anti-corrosion, heat-resisting, the antioxygenic property on chain nest 2 surfaces.

The sprocket wheel that is used for slat conveyer that the utility model provides, because chain nest 2 surfaces are provided with laser cladding coating 3, thereby in the situation of the character that does not affect sprocket body 1, not only prepare performance-oriented alloy surface on chain nest 2 surfaces, saved valuable Rare Metals Materials, reduced cost, and wear-resisting, anti-corrosion, heat-resisting, the antioxygenic property of chain nest 2 are strengthened greatly, prolonged the service life of sprocket wheel, reduced the maintenance cost under the coal mine, economic benefit is very high.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims

1. be used for the sprocket wheel of slat conveyer, comprise sprocket body, have the chain nest on the described sprocket body, it is characterized in that described chain nest surface is provided with laser cladding coating.

2. the sprocket wheel for slat conveyer according to claim 1 is characterized in that, described laser cladding coating thickness is 0.2-2mm.
