Description

Technical Field

[0001] This utility model belongs to the field of spacer technology, and specifically relates to a novel spacer. Background Technology

[0002] Spacers are used in transportation equipment such as vehicles, machinery, and conveyor belts to separate parts. Existing spacers typically have a flat, curved inner ring surface that is in close contact with the shaft. During installation, oil and dirt easily accumulate in the gap between the inner ring surface and the shaft surface, making it difficult for the spacer to slide smoothly and hindering installation. During the installation of a ring cutter, as the spacer moves on the shaft, the edges of the inner ring surface scrape against oil and dust from the shaft surface, causing them to accumulate on the spacer's end face and eventually press between the spacer's end face and the shaft surface, affecting installation accuracy, wasting resources, and in severe cases, damaging the shaft surface. Furthermore, when it is necessary to remove or replace the spacer, prolonged contact with other components can cause it to stick to them, making removal difficult.

[0003] Therefore, it is necessary to provide a new type of spacer to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a novel spacer to solve the technical problems of oil stains accumulating in the gap between the inner ring surface and the shaft surface, and the spacer sticking to other parts and being difficult to remove after prolonged contact with them.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel spacer, comprising: a collar, wherein the collar has a through hole in the middle, and inner rings are provided on both the upper and lower surfaces inside the collar, an inner ring groove is provided between the collar and the inner rings, and finger pits are provided at both ends of the diameter of the lower part of the outer surface of the collar.

[0006] As further explained, the thickness of the inner ring is greater than the thickness of the outer ring.

[0007] As further explained, the cross-section of the finger pit is arc-shaped.

[0008] As a further explanation, the outer edge of the side of the finger pit is provided with a chamfer transition.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The inner ring groove is provided inside the collar to prevent oil and dust from accumulating in the gap between the collar and the shaft surface, thus affecting the sliding of the collar on the shaft. On the other hand, some oil and dust enter and are stored in the inner ring groove, which reduces the amount of oil and dust accumulating between the end face of the collar and the surface of the shaft, thereby improving the installation and positioning accuracy of the shaft.

[0011] 2. By providing the inner ring groove inside the collar, the weight of the collar can be reduced, while saving material costs.

[0012] 3. Finger recesses are provided at both ends of the diameter below the outer surface of the collar, making it easy for workers to lift and remove the collar with their fingers. This prevents the collar from sticking to other parts and becoming difficult to remove when it needs to be removed or replaced due to prolonged contact with other parts.

[0013] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention are realized and obtained through the structures particularly pointed out in the description and the accompanying drawings.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figure 1-2A novel spacer includes a collar 1, which is circular in shape and has a through hole 2 in the middle. The through hole 2 is cylindrical in shape. Inner rings 3 are provided on both the upper and lower surfaces inside the collar 1. The inner rings 3 are located on the outermost ring inside the collar 1. An inner ring groove 4 is provided between the collar 1 and the inner rings 3. Finger pits 5 are provided at both ends of the diameter of the lower part of the outer surface of the collar 1.

[0022] like Figure 2 As shown, the thickness of the inner ring 3 is greater than the thickness of the outer ring 1. The thicker the inner ring 3, the larger the capacity of the inner ring groove 4, ensuring that the inner ring groove 4 has sufficient storage space.

[0023] like Figure 2 As shown, the cross-section of the finger pit 5 is arc-shaped, which conforms to the shape of a human finger, making it convenient for the finger to be inserted into the finger pit 5.

[0024] like Figure 2 As shown, the outer edge of the side of the finger pit 5 is chamfered to prevent the finger from being scratched when it is inserted into the finger pit 5 and flipped upwards.

[0025] Working principle: When the shaft is used in conjunction with this new type of spacer, the shaft is inserted and installed through the through hole 2. The spacer has an inner ring 3 inside, and an inner ring groove 4 is formed between the inner ring 3 and the collar 1. The inner ring groove 4 effectively prevents oil and dust from accumulating in the gap between the inside of the collar 1 and the shaft surface, thus affecting the sliding of the collar 1 on the shaft. On the other hand, some oil and dust enter and are stored in the inner ring groove 4, which reduces the amount of oil and dust accumulating between the end face of the collar 1 and the surface of the shaft, and improves the installation and positioning accuracy of the shaft.

[0026] Furthermore, when it is necessary to remove or replace the spacer, other spacers may stick to other parts after prolonged contact and are therefore difficult to remove. However, with this new type of spacer, workers can insert their fingers into the finger pit 5 and flip the spacer up from the finger pit 5 to remove it.

[0027] All the devices selected in this application (parts whose specific structures are not specified) are general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
