The gear rail of the plate scraper is also called pin row and pin rail, which is suitable for the scraper conveyor and the central trough part of the transfer machine in the coal mine. Material: 42CrMo, 40CrMoSi, 30MnSi.
The gear rail of the plate scraper is placed on the gear rail seat, which is the track that the shearer travels on. The gear rail seat is welded on the middle groove side. The gear rail seat and the gear rail are connected with the gear rail pin.
According to pitch specification, the gear rail of scraper machine can be divided into: 126 pitch rail, 147 pitch rail; According to the number of pitch can be divided into: 3 pitch gear rail, 4 pitch gear rail, 5 pitch gear rail, 6 pitch gear rail, 7 pitch gear rail, 8 pitch gear rail, 9 pitch gear rail.
The tooth track is an indispensable important part in the supporting production of three fully mechanized coal mining. The gear rail is placed on the gear rail seat, which is the walking track of the shearer. The gear rail seat is welded on the middle groove top, and the gear rail seat and the gear rail are connected through the gear rail pin. Therefore, in addition to the need to have a suitable tooth hole, the rail also needs to have a high strength and stability.
The gear rail belongs to the deep hole thin wall complex forging, the forging mass is big and the shape is complex, forming difficulty is big. Tooth rail, also known as pin rail, tooth rail bar, alloy steel forging or casting, meshing tooth surface for arc teeth, with high meshing intensity, can reduce the impact; It is installed in the rail seat of chute and fixed with pin shaft.
The coal mine tooth rail disassembly and repair is convenient and quick, According to the pitch, pitch quantity, casting and forging parts, host manufacturers to arrange production rationally, to create a conscience quality! Provide good service for you! Looking forward to working with you hand in hand!
