Problems solved by technology
[0004] Under the existing technology, during the operation of the pulley, the pulley often pushes the rib bearing to move towards the rib bearing, which eventually causes the position of the pulley to deviate, causing the pulley to interfere with the surrounding mechanisms or the belt transported on the pulley to be separated from the pulley. Interference with other parts of the machine, causing wear to pulleys and belts, and damage to other parts

Abstract
The invention discloses a belt pulley rotating device. The rotating device comprises a rotary shaft (5) connected with a belt pulley (2) and a bearing arranged around the rotary shaft (5), wherein the bearing is provided with a locking ring (4), the locking ring (4) and the belt pulley (2) are arranged on both sides of the bearing respectively, and the outer surface of the bearing is provided with a fixed sleeve (1). The belt pulley turning device has the advantage that the belt pulley turning device can avoid the positional deviation of the belt pulley.
Description
technical field [0001] The invention relates to a pulley rotating device. Background technique [0002] Pulleys are mainly used for long-distance transmission of power, such as the output of small diesel engine power, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, some small horsepower motorcycle power Transmission, agricultural machinery power transmission, air compressor, reducer, reducer, generator, cotton gin, etc. [0003] Belt pulleys are often matched with rib bearings. Rib bearings are the most representative rolling bearings. They are widely used and are suitable for high or even extremely high speed operations. They are also very durable and require no frequent maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost, easy to achieve high manufacturing accuracy, and various size ranges and forms...
