Oil-immersed chain transmission assembly

The technical problem to be solved by the utility model is to provide the oil-immersed chain transmission component, a driving chain wheel and a driven chain wheel are sealed and surrounded by an oil box, so that a double-row chain is immersed in oil, real-time online lubrication of the double-row chain is realized, frequent regular work of frequent chain oil injection maintenance is avoided, and the service life of the chain is prolonged. Meanwhile, the production abnormal accidents of shutdown of the slag drying machine caused by the fact that a chain is not maintained in place are greatly reduced, and the slag drying machine comprises a driving chain wheel connected with an output shaft of a motor, a driven chain wheel connected with an input shaft of a speed reducer and an oil box, and the driving chain wheel and the driven chain wheel are coaxially distributed side by side. The driving chain wheel and the driven chain wheel are in transmission through a double-row chain, the driving chain wheel, the driv
