The sprocket shaft group is the driving part of the scraper chain, which is mainly composed of shaft, bearing, bearing seat, through cover, support sleeve, floating oil seal assembly, sprocket, positioning sleeve, etc. The sprocket shaft group is centralized with oil tank for thin oil lubrication, and the lubricating oil is L-CKC320 extreme pressure gear oil. The oil tank is fixed on the baffle at the reducer side. Two oil pipes are connected from the lower end, one is the oil inlet pipe (Y), the other is the exhaust pipe (Q) (note that the oil pipe end and the oil connection pipe are marked with Y and Q). The lubricating oil enters the sprocket shaft group from the end cover at the non reducer side through the oil pipe passing through the head frame. The upper end of the end cover is connected with the exhaust pipe, and the lower end joint is connected with the oil pipe.
The chain wheel is forged from alloy steel. In order to enhance its strength and extend its service life, quenching and tempering and surface hardening treatment are adopted. Generally, the tooth surface on one side is worn after being put into use It is recommended to change the installation direction of the sprocket about 3mm, and change its stressed tooth surface sprocket assembly, which is composed of bearing cover, bearing seat, sprocket shaft, floating seal ring, rolling bearing, screw plug (M12 × 1.25), etc. It is mainly used to install on the head frame to transmit power. The center distance between the two sprockets is 90mm, and the number of teeth is 7. The sprocket is made of alloy steel and integrally forged, and its tooth shape is processed by forming milling cutter. In order to enhance its strength and extend its service life, quenching and tempering and surface hardening treatment are adopted. Generally, after being put into use, when the tooth surface on one side is worn about 2mm, it is recommended to change the installation direction of the sprocket and change its stressed tooth surface to extend its service life.
