Description

Technical Field

[0001] The utility model belongs to the technical field of belt rollers, and in particular relates to a transmission belt roller shaft seat which is easy to replace. Background Art

[0002] Belt rollers, also called pulleys, belong to the hub type parts. They are generally relatively large in size, and the manufacturing process is generally based on casting and forging. Generally, larger designs are cast, and the material is generally cast iron (better casting performance), and cast steel is rarely used (steel has poor casting performance); generally, smaller ones can be designed for forging, and the material is steel. Pulleys are mainly used in situations where power is transmitted over long distances, such as the output of small diesel engine power, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging machines, some small horsepower motorcycle power transmission, agricultural machinery power transmission, air compressors, reducers, reducers, generators, cotton gins, etc.

[0003] In the case of long-term use and wear of the pulley, the pulley needs to be replaced. The shaft seat of the pulley and the pulley shaft are generally matched. If the shaft seat is not damaged, replacing the shaft seat and the belt roller together will cause waste. However, the existing pulley shaft seat matches the pulley size. When replacing other belt rollers, the new belt roller’s thickness and shaft length will make it difficult to install the new belt roller and shaft seat, making replacement more troublesome.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0029] Specifically, the diameter of the side of the preferred T-shaped shaft 12 away from the belt roller body 9 is larger than the diameters of the first semicircular groove 5 and the second semicircular groove 6, which can prevent the T-shaped shaft 12 from escaping from the first semicircular groove 5 and the second semicircular groove 6. When the belt roller body 9 needs to be installed, the third body 3 of the shaft seat is rotated, and the third body 3 of the shaft seat is rotated to a state flush with the upper end of the second body 2 of the shaft seat, and the rotating shaft 10 is inserted into the shaft groove 11. The third body 3 of the shaft seat is rotated so that the third body 3 of the shaft seat is in a vertical state with the second body 2 of the shaft seat. At this time, the T-shaped shaft 12 is located in the first semicircular groove 5, and the clamping plate 4 is rotated to clamp the clamping plate 4 on the circumferential side of the T-shaped shaft 12.
