Description

Technical Field

[0001] The utility model belongs to the technical field of lubrication, and in particular relates to a grease lubricating rotary distribution device for a sprocket assembly. Background Art

[0002] Scraper conveyors are the primary transport equipment for transporting coal from underground coal mining faces. They utilize an endlessly circulating scraper chain that loops around the nose and tail wheels as the traction mechanism, and a chute as the load-bearing mechanism to transport the coal. Within the drive system of a scraper conveyor, the sprocket assembly is a crucial component for transmitting power. During operation, the sprocket assembly is subject to pulsating cyclic loads and impact loads from coal flakes and gangue. The sprocket assembly of a scraper conveyor requires constant lubrication. Lubricants not only reduce friction but also dissipate heat, reduce contact stress, absorb vibration, and prevent corrosion. Sprocket assemblies are typically lubricated with thin oil. A tank containing the lubricant is suspended from the equipment and connected to the sprockets via an oil filling line. The fluid lubricant flows under gravity into the sprocket assembly, lubricating the bearings. The sealing chamber utilizes a floating seal. During sprocket assembly operation, a low lubricating oil level or poor oil quality can cause the unit to overheat. If not corrected promptly, this can damage bearings and seals, which in turn can lead to damage to the frame and transmission components. Therefore, operators must constantly check the oil level in the tank to determine if the lubricant needs to be replenished. However, due to the harsh operating conditions of the sprocket assembly and its structural dimensions constrained by the equipment's structural space, lubricating oil replacement is difficult and seals are prone to failure, leading to frequent oil leaks during operation. Oil leaks not only waste significant lubricating oil and pollute the operating environment, but also can damage the sprocket assembly bearings if not promptly detected and addressed. Replacing the sprocket assembly bearings requires disassembling the entire sprocket assembly and replacing it with a suitable one. This labor-intensive process often takes several hours, disrupting normal production. When the sprocket assembly is brought up for repair, it must be completely disassembled and replaced with new parts, increasing repair costs, labor intensity, low worker efficiency, and lengthy maintenance times.
