Description

Technical Field

[0001] This utility model relates to the field of shaft and wheel connection structures, specifically a stepped lightweight shaft and wheel connection structure. Background Technology

[0002] In mechanical transmission systems, double-row chain drives are widely used due to their high transmission efficiency and load-bearing capacity. However, the connection structure between the shaft and sprocket in traditional double-row chain drive components has many shortcomings.

[0003] On the one hand, the sprocket's overall structure is relatively thick and heavy, generating significant load and inertia during operation, increasing system energy consumption and negatively impacting the transmission system's response speed and stability. On the other hand, the bearings at the shaft-sprocket connection are prone to wear after prolonged use. When repairing or replacing worn bearings, due to unreasonable dimensional design at the shaft, bearing, and sprocket connection, welding and grinding to repair the shaft surface wear results in a large interference fit between the bearing and shaft, making disassembly difficult. This significantly increases maintenance difficulty and cost, reduces equipment maintenance efficiency, and affects normal equipment operation. Therefore, a stepped, lightweight shaft-sprocket connection structure needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a stepped lightweight shaft and wheel connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepped lightweight shaft and wheel connection structure, including a shaft body, the surface of which is provided with a double row of sprockets, the double row of sprockets including two wheel bodies arranged in parallel to each other, and grooves being provided on both sides of the double row of sprockets.

[0006] Preferably, a bearing is provided on the left side of the shaft surface.

[0007] Preferably, the diameter of the end of the shaft that connects to the double-row sprocket is designed to be 28mm.

[0008] Preferably, the inner diameter of the mating hole between the double-row sprocket and the shaft is 28mm.

[0009] Preferably, the inner diameter of the bearing and the shaft body is 30mm.

[0010] Preferably, the shaft diameter connecting the shaft body and the bearing is set to 30mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This stepped lightweight shaft and wheel connection structure, by setting up the shaft and bearing, allows the special size design of the connection part between the shaft and the double-row sprocket to directly weld and grind the 28mm diameter part of the shaft when the bearing needs to be replaced due to wear or the shaft surface needs to be repaired due to wear. After repair, the bearing can be easily removed from the shaft, which facilitates the replacement and maintenance of the bearing and effectively improves the maintenance convenience and operational reliability of the equipment.

[0013] 2. This stepped lightweight shaft and wheel connection structure, by opening grooves on both sides of the double-row sprockets, reduces the load and inertia caused by the weight of the double-row sprockets when driving the chain transmission, thereby improving the transmission efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please refer to Figure 1-3 As shown, this utility model provides a stepped lightweight shaft and wheel connection structure, including a shaft body 1. The surface of the shaft body 1 is provided with a double row of sprockets 2. The double row of sprockets 2 includes two wheel bodies 3 arranged in parallel with each other. Grooves 4 are provided on both sides of the double row of sprockets 2. By providing grooves 4 on both sides of the double row of sprockets 2, the load and inertia caused by its own weight are reduced when the double row of sprockets 2 drives the chain transmission, thereby improving the transmission efficiency.

[0021] Specifically, a bearing 5 is provided on the left side of the surface of the shaft 1. The diameter of the end of the shaft 1 connected to the double-row sprocket 2 is designed to be 28mm. The inner diameter of the mating hole between the double-row sprocket 2 and the shaft 1 is 28mm. The inner diameter of the mating hole between the bearing 5 and the shaft 1 is 30mm. The shaft diameter connecting the shaft 1 and the bearing 5 is set to 30mm. Through the special dimensional design of the connection part between the shaft 1 and the double-row sprocket 2, when the bearing 5 is worn and needs to be replaced, or when the surface of the shaft 1 is worn and needs to be repaired, the 28mm diameter part of the shaft 1 can be directly welded and ground. After repair, the bearing 5 can be easily removed from the shaft 1, which facilitates the replacement and maintenance of the bearing 5 and effectively improves the maintenance convenience and operational reliability of the equipment.

[0022] Working principle: This utility model is a stepped lightweight shaft and wheel connection structure. By opening grooves 4 on both sides of the double-row sprocket 2, the load and inertia caused by the weight of the double-row sprocket 2 are reduced when driving the chain transmission, thereby improving the transmission efficiency. When the bearing 5 is worn and needs to be replaced, or when the surface of the shaft 1 is worn and needs to be repaired, due to the special size design of the connection part between the shaft 1 and the double-row sprocket 2, the 28mm diameter part of the shaft 1 can be directly welded and ground. After repair, the bearing 5 can be easily removed from the shaft 1, which facilitates the replacement and maintenance of the bearing 5 and effectively improves the maintenance convenience and operational reliability of the equipment.
