Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to an improved roller structure. Background Art

[0002] At present, rollers are used as steering support components of transport equipment when it is working. The rollers are generally arranged in the form of a hub and a connecting plate. However, the above structure needs to be manufactured at the corresponding position of a key groove for installing the hub, which increases the processing cost. At the same time, the hub is required as a support component at both ends of the roller, which also increases the production cost of the entire product. For example, the published patent 202411082334.8 discloses a belt conveyor roller and a belt conveyor, wherein the belt conveyor roller includes a cylinder, a rotating shaft, a first hub, a second hub, a first tensioning assembly and a second tensioning assembly, the rotating shaft is inserted into the cylinder and is spaced apart from the inner circumferential surface of the cylinder, the first hub and the second hub are both sleeved on the rotating shaft and are spaced apart relative to each other along the circumferential direction of the rotating shaft, the first hub and the second hub are respectively arranged at the left and right ends of the cylinder and are connected to the left and right ends of the cylinder, the first tensioning assembly and the second tensioning assembly are both sleeved on the rotating shaft, the first tensioning assembly is arranged between the first hub and the rotating shaft and is connected to the first hub and the rotating shaft, the second tensioning assembly is arranged between the second hub and the rotating shaft and is connected to the second hub and the rotating shaft. The belt conveyor of the present invention has the advantages of simple structure, low cost, and long service life. However, the above structure still needs to use a hub, which means that the processing cost is still high. Therefore, it is particularly important to solve the problem of high processing cost and raw material cost caused by the use of a hub on the roller. Summary of the invention

[0003] The purpose of the present invention is to provide an improved roller structure, which uses a double expansion sleeve structure instead of a double key structure, does not need to process keyways, and does not need to use a hub structure, thereby simplifying the structure and reducing production costs. In addition, since the hub structure is not used, welding points are reduced, and machining after correction is convenient, thus solving the problem of high processing costs and raw material costs caused by the use of a hub for the roller.

[0004] The present invention provides an improved roller structure, comprising a bearing seat, a roller, a tube skin and a connecting key, wherein the number of the bearing seats is two and they are arranged opposite to each other, the two ends of the roller are installed in the bearing seats, the tube skin is wrapped around the outside of the roller, a connecting plate is arranged between the tube skin and the roller, the connecting plate is fixed on the roller through an expansion sleeve, and the outer periphery of the connecting plate is welded to the inside of the tube skin.

[0005] A further improvement is that a vibration probe is provided on the bearing seat, and whether the roller installed in the bearing seat is vibrating is detected by the vibration probe.

[0006] A further improvement is that a vibration indicator light is provided on the bearing seat, and the vibration indicator light is connected to the vibration probe signal. When the vibration probe senses vibration, the vibration indicator light lights up to indicate danger.

[0007] A further improvement is that a tension block is provided between the connection disk and the expansion sleeve, and the sealing and tightness between the connection disk and the expansion sleeve are improved by the tension block.

[0008] A further improvement is that: the tube skin is provided with anti-slip grooves, and the middle section of the tube skin is provided with a protrusion.

[0009] A further improvement is that an oil seal groove is reserved on the bearing seat, and the bearing seat is sealed through the oil seal groove.

[0010] The beneficial effects of the present invention are as follows: a double expansion sleeve structure is used instead of a double key structure, and there is no need to process keyways or use a hub structure, which simplifies the structure and reduces production costs. Furthermore, since a hub structure is not used, welding points are reduced, which facilitates machining after correction. At the same time, since welding points are reduced, the processing difficulty is greatly reduced, and product consistency is enhanced. The expansion sleeve is assisted in tightening by a tensioning block, which improves product stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] like Figure 1-2As shown, this embodiment provides an improved roller structure, including a bearing seat 1, a roller 2, a tube skin 3 and a connecting key 4. The number of the bearing seats 1 is two and they are arranged oppositely. The two ends of the roller 2 are installed in the bearing seat 1, and the tube skin 3 is wrapped around the outside of the roller 2. A connecting plate 4 is arranged between the tube skin 3 and the roller 2. The connecting plate 4 is fixed on the roller 2 through an expansion sleeve 5, and the outer periphery of the connecting plate 4 is welded to the inside of the tube skin 3. A vibration probe 6 is arranged on the bearing seat 1, and the vibration probe 6 is used to detect whether the roller 2 installed in the bearing seat 1 has a beating. A vibration indicator light 7 is arranged on the bearing seat 1, and the vibration indicator light 7 is connected to the vibration probe 6 signal. When the vibration probe 6 senses vibration, the vibration indicator light 7 lights up to indicate danger. A tension block 8 is arranged between the connecting plate 4 and the expansion sleeve 5, and the tension block 8 is used to improve the sealing and tightness between the connecting plate 4 and the expansion sleeve 5. Anti-slip grooves 9 are arranged on the tube skin 3, and a protrusion 10 is arranged in the middle section of the tube skin 3. The bearing seat 1 is provided with an oil seal groove 11, and the bearing seat 1 is sealed by the oil seal groove 11. The outer periphery of the receiving disc is welded to the inner circle of the drum skin, and the inner hole of the receiving disc and the shaft are connected by a Z8 expansion sleeve, and the assembly of the roller bearing seat is completed. The double expansion sleeve structure is used instead of the double key structure, and there is no need to process the keyway, and there is no need to use the hub structure, which simplifies the structure and reduces the production cost. In addition, since the hub structure is not used, the welding points are reduced, which facilitates the machining after correction. At the same time, due to the reduction of welding points, the processing difficulty is greatly reduced, and the product consistency is enhanced. The expansion sleeve 5 is assisted by the tensioning block 8 to tighten the product stability.
