Abstract

The invention relates to the technical field of self-lubricating conveying chains, and provides a self-lubricating structure of a double-row heavy-load cement conveying chain. The self-lubricating structure effectively improves the lubrication sufficiency of the conveying chain, enhances the high temperature resistance, wear resistance, impact fatigue resistance and the like of the chain, and prolongs the service life of the chain. The self-lubricating structure comprises two closed structures defined by a plurality of chain links, and the two closed structures are arranged in parallel. The self-lubricating structure is characterized in that each chain link comprises an inner chain plate, an outer chain plate and a pin shaft, wherein the outer chain plates and the inner chain plates are oppositely and alternately connected through the pin shafts, a roller is arranged between every two inner chain plates, a sleeve is inserted in the middle of each roller, each sleeve is arranged on thecorresponding pin shaft in a sleeving mode, the pin shafts are in large clearance fit with the sleeves, the inner end of each pin shaft is provided with an end step, the other end of each pin shaft isprovided with an oil groove, and an oil cup is installed at a port of each oil groove in a threaded manner. The self-lubricating structure is particularly suitable for self-lubricating of the heavy-load conveying chain, and has high social use value and application prospects.

Description

technical field

[0001] The invention relates to the technical field of self-lubricating conveyor chains, in particular to a self-lubricating structure of a double-row heavy-duty cement conveyor chain. Background technique

[0002] The heavy-duty cement conveyor chain is mainly used for various conveying equipment in cement plants. It is mainly used in limestone reclaimers, coal and concrete conveyors, bucket elevators, clinker conveyors and other equipment. The chain is the transmission of these conveying equipment Parts, transmitting motion and power, conveying limestone, coal slag, stone clinker and other materials, the working conditions are very harsh, the load is relatively large, and the wear is relatively severe, which requires the chain to be resistant to high temperature, wear and fatigue. .

[0003] The two chains are connected in series by lengthening the pin shaft to form a set of double-row chains. When the chains are running on the machine, they must run synch...
