AI Technical Summary
Poor bearing lubrication in scraper conveyors can lead to uneven sprocket rotation resistance, chain misalignment, and chain breakage. Existing manual maintenance methods are time-consuming, labor-intensive, and difficult to prevent malfunctions, thus affecting the stable operation of the equipment.
Design a protective structure for a scraper conveyor, including an oil injection module, a torque limiter, and a detection component to achieve automatic lubrication and overload protection. The oil injection module automatically lubricates the bearing with each revolution, the torque limiter cuts off power transmission in case of overload, and the detection component monitors and alarms in real time.
It significantly extends the lubrication cycle, reduces the frequency of manual maintenance, prevents malfunctions caused by poor lubrication, ensures stable equipment operation, reduces the risk of production interruption, and improves equipment efficiency and reliability.
