AI Technical Summary
Traditional elevator balance compensation chain guide devices cannot apply lubricating oil on their own during elevator operation, resulting in severe wear of the shaft, high friction noise, and complex maintenance operations.
Design a guide device with lubrication components, including an oil reservoir, an oil supply pipe, an oil inlet, and a sealing sleeve. Lubricating oil is automatically applied during elevator operation via a micro control valve. The lubricating oil enters the rotating shaft through the oil supply pipe and is sprayed onto the friction parts, reducing friction noise and preventing rust.
It enables the automatic application of lubricating oil during elevator operation, reducing noise, extending the service life of the guide device, and preventing rust.
