Industry information
Shearer sprocket
The shearer sprocket is used by Dafan in chemical industry, rapid equipment mechanical equipment, food treatment processing, gas high-tech, forming and other old equipment mechanical equipment blocks, etc.
Inner construction of coal shearer sprocket
The tooth profile of the shearer sprocket is lower than that of the maintenance chain, which saves and consolidates and facilitates participation and investment in the link. It is best to lower the link attack and touch stress during the link, and understand the processing well.
The tooth profile of the sprocket of the commonly used shearer.This is composed of three arcs aa, ab, cd and four circles bc, and the program has three arcs-circular tooth shape.The tooth profile is connected and processed by the code of mortar. On the working drawing of the shearer sprocket, the grille is turbulent and the end face tooth profile, as long as everyone is technically "the tooth profile is manufactured according to the 3RGB1244-85 rule", but the shearer should be turbulent. For the tooth profile of the shaft surface of the sprocket, please refer to the non-dry construction manual.
. The inner part of the shearer sprocket
The sprocket used for the shearer basically generally leads to the main type of the object, and the sprocket used for the shearer usually leads to the spoke type. For quick handling, loading and reduction, the cable on the spokes is used for the shearer. The sprocket can lead to the mortar connection type, the fireproof ring gear and the wheel core are made with different contents to remove dust!, not automatic and so on.
. Shearer sprocket content
The content of the shearer sprocket should maintain a little bit of use and manufacturability. Therefore, the tooth surface of the shearer sprocket is basically thermally cleaned to remove the alloy.
Maintenance and replacement of shearer sprocket
The flexibility of the shearer sprocket should be appropriate. Too tight will increase the cost of asbestos and carry out the bearing dye; if the shearer sprocket is too loose, the dye stays and de-chains.The low flexibility of the shearer sprocket is: from the shearer sprocket easy to excavator sprocket or press down, it is about 2%-3% of the clinic distance between the two shearer sprocket.
, The safety shaft of the shearer sprocket should be insulated, illuminated and tilted.In the same block equipment, the end face of some shearer sprocket should be in the same major event plane. When the shearer sprocket clinic distance is 0.5 meters, it is best to lean toward the furniture; the shearer sprocket clinic distance is .5 meters In the first few hours, it is best to lean towards furniture.But it is not best to have the problem of the shearer sprocket teeth actually play out, so the two-wheel offset shortcomings of dyes are de-chained and improved.When maintaining the shearer sprocket, the sprocket of the shearer is lower than the excellent completion inspection and decomposing offset.
