Description

Technical Field

[0001] The utility model relates to a support shaft, in particular to a novel concentricity support shaft. Background Art

[0002] The support shaft can be used as a very important mechanical component in many mechanical assembly places. These support shafts can provide support for the bottom of some mechanical components, and can also rely on the support shaft to provide support on the sides of the mechanical components. A support seat supporting the support shaft is provided on the support shaft. The support seat can make the support of the support shaft more stable. When the support shaft is further assembled, the concentricity of the support shaft assembly needs to be considered well, and the concentricity needs to be further adjusted and improved.

[0003] In the prior art: CN202222188842.7 Wheel-side deceleration support shaft, the utility model discloses a wheel-side deceleration support shaft, which relates to the technical field of automobile accessories, including a deceleration support shaft and a deceleration support seat. The wheel-side deceleration support shaft, through the coordinated use of the deceleration support shaft, the sleeve tube and the deceleration support seat, enables the deceleration support shaft and the deceleration support seat of the wheel-side deceleration support shaft to be connected and fixed by threads. When in the connected state, the thread at the end of the deceleration support shaft is connected to the second threaded area in the assembly groove, and the thread inside the sleeve tube is docked with the first threaded area outside the deceleration support seat, thereby ensuring the stability of the deceleration support shaft and the deceleration support seat in the connected state. Rotating the deceleration support shaft and the deceleration support seat can simultaneously realize the separation between the thread at the end of the deceleration support shaft and the thread inside the sleeve tube and the second threaded area and the first threaded area.

[0004] The support shaft in the prior art can realize convenient disassembly and replacement by relying on the reduction support shaft and the reduction support seat of the wheel side reduction support shaft, but the support shaft in the prior art cannot be well injected with lubricating oil and cannot ensure the concentricity of the support shaft.

[0006] The utility model is implemented by the following technical solution: a new concentricity support shaft is provided with a bottom support plate, an assembly hole is provided on the bottom support plate, an assembly bolt is provided in the assembly hole, an upper boss is provided on the bottom support plate, the upper boss is divided into a left boss and a right boss, a support shaft assembly hole is provided on the left boss and the right boss, an assembly space is provided in the support shaft assembly hole, a support shaft is provided in the assembly space, and a lubricating component is provided on the support shaft assembly hole.

[0007] The lubricating component is a lubricating hole, which passes through the supporting shaft assembly hole, and a lubricating transmission channel is provided in the lubricating hole.

[0008] The support shaft assembly hole is provided with a concentricity adjustment component, the concentricity adjustment component is a concentricity adjustment groove, and the support shaft is provided with an adjustment valve block.

[0009] The support shaft is assembled in the support shaft assembly hole, and the adjustment valve block on the support shaft is inserted into the concentricity adjustment groove during the support shaft assembly process.

[0010] Side support plates are provided on the left boss and the right boss. The side support plates are welded to the left boss and the right boss. The side support plates are triangular support plates.

[0011] Compared with the prior art, the present invention needs to rely on the bottom support plate for further bottom support when the support shaft needs further bottom support. An upper boss is provided on the bottom support platform, and the upper boss is divided into a left boss and a right boss. Support shaft assembly holes are provided on the left boss and the right boss. The support shaft assembly holes can be used to further assemble and fix the support shaft. A concentricity adjustment groove is provided on the support shaft assembly hole, and an adjustment valve block is provided on the support shaft. By relying on the mutual assembly of the adjustment valve block and the concentricity adjustment groove, the support shaft can meet the concentricity installation requirements of the support shaft when it is further assembled.

DETAILED DESCRIPTION

[0016] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] A new concentricity support shaft is provided with a bottom support plate 1, an assembly hole is provided on the bottom support plate 1, an assembly bolt 2 is provided in the assembly hole, an upper boss is provided on the bottom support plate 1, and the upper boss is divided into a left boss 3 and a right boss 4, a support shaft assembly hole 5 is provided on the left boss 3 and the right boss 4, an assembly space is provided in the support shaft assembly hole 5, a support shaft 6 is provided in the assembly space, and a lubrication component is provided on the support shaft assembly hole 5.

[0018] When the support shaft needs to be further assembled, the support shaft 6 can be assembled in the support shaft assembly hole 5. The support shaft assembly hole 5 can be used to better fix the support shaft. In order to make the lubrication effect of the support shaft 6 better, further lubrication can be performed at the connection between the support shaft assembly hole 5 and the support shaft 6. When lubricating oil needs to be injected, especially at the connection between the support shaft assembly hole 5 and the support shaft 6, it is necessary to rely on a lubricating component. The lubricating component can be used to inject lubricating oil well. The lubricating component is a lubricating hole 7. The lubricating hole 7 passes through the support shaft assembly hole. A lubrication transmission channel is provided in the lubricating hole 7. The operator injects the lubricating oil from the lubricating hole 7, and then the lubricating oil will flow into the connection between the support shaft assembly hole 5 and the support shaft 6, which can further improve the lubrication effect of the support shaft 6.

[0019] In order to improve the concentricity of the support shaft 6 during assembly, a concentricity adjustment component can be used to ensure the concentricity, so a concentricity adjustment component is provided on the support shaft assembly hole 5, and the concentricity adjustment component is a concentricity adjustment groove 8. An adjustment valve block 9 is provided on the support shaft 6, and the support shaft 6 is assembled in the support shaft assembly hole 5. The adjustment valve block 9 on the support shaft 6 is inserted into the concentricity adjustment groove 8 during the assembly process of the support shaft 6. An adjustment valve block 9 is provided on the support shaft 6, and the adjustment valve blocks 9 are distributed on both sides of the support shaft 6. The assembly is carried out by relying on the concentricity adjustment groove 8 set in the support shaft assembly hole 5 to meet the mutual cooperation between the adjustment valve block and the concentricity adjustment groove 8, which can well ensure the concentricity of the support shaft 6 and meet the assembly requirements of the support shaft.

[0020] A left boss 3 and a right boss 4 are provided on the bottom support plate 1. Relying on the support shaft assembly holes 5 on the left boss 3 and the right boss 4, support is required on both sides of the left boss 3 and the right boss 4. Therefore, a side support plate 10 is provided on the left boss 3 and the right boss 4. The side support plate 10 is welded to the left boss 3 and the right boss 4. The side support plate 10 is a triangular support plate.

[0021] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
