Description

Technical Field

[0001] This utility model relates to the technical field of shaft spacers with high fitting degree, and in particular to a shaft spacer with high fitting degree. Background Technology

[0002] A shaft spacer is a component used to separate parts on the same shaft. Its function is to fill the gaps along the shaft's length to prevent parts from shifting, or to separate two parts on the shaft by a certain distance so that they can receive motion from different transmission paths without collision or friction. Shaft spacers are often installed by embedding them into an annular groove in the shaft. However, embedding shaft spacers into an annular groove is often difficult to install and disassemble. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shaft spacer with high fit.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a shaft spacer with high fit, including a spacer body and a matching mounting shaft. The spacer body is composed of two identical half-spacers. A limiting groove is formed annularly on the surface of the mounting shaft, and the spacer body is embedded in the limiting groove. Each half-spacer has an insertion block and an insertion groove at both ends. A threaded hole is formed on the upper inner wall of the insertion groove, and a threaded groove is formed on the lower inner wall of the insertion groove. A through hole is formed on the surface of the insertion block, and the insertion block extends into the insertion groove of the other half-spacer. A bolt is threadedly connected to the threaded hole, and the lower end of the bolt passes through the through hole and is threadedly connected to the threaded groove.

[0006] Preferably, each end of the semi-partition is provided with two connecting posts and two connecting slots, with the two connecting posts corresponding one-to-one with the two connecting slots, and the connecting posts extending into the connecting slots provided in the other semi-partition.

[0007] Preferably, the corners of the inner wall of the semi-partition are rounded.

[0008] Preferably, the corner where the limiting groove meets the outer surface of the mounting shaft is rounded.

[0009] Preferably, a disassembly groove is provided at the middle position of both the front and rear surfaces of the semi-partition.

[0010] Preferably, a concealed groove is provided on the outer side of the screw hole, and the bolt consists of a stud and a nut, with the nut disposed in the concealed groove.

[0011] The present invention proposes a shaft spacer with high fit, which has the following advantages: the spacer body is divided into two half spacers, and the two half spacers are connected by bolts. The spacer body can be quickly installed into the limiting groove set on the mounting shaft. The installation is very easy and the disassembly is also very convenient. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 A high-fitting shaft spacer includes a spacer body and a matching mounting shaft 1. The spacer body is composed of two identical half-spacers 3. A limiting groove 4 is formed annularly on the surface of the mounting shaft 1. The spacer body is embedded in the limiting groove 4. The two ends of the half-spacers 3 are respectively provided with an insertion block 5 and an insertion groove 6. A screw hole 7 is formed on the upper inner wall of the insertion groove 6, and a screw groove 8 is formed on the lower inner wall of the insertion groove 6. A through hole 9 is formed on the surface of the insertion block 5. The insertion block 5 extends into the insertion groove 6 of the other half-spacer 3. A bolt 2 is threadedly connected to the screw hole 7. The lower end of the bolt 2 passes through the through hole 9 and is threadedly connected to the screw groove 8.

[0019] The two ends of the half-partition 3 are respectively provided with two connecting posts 10 and two connecting slots 11. The two connecting posts 10 and the two connecting slots 11 correspond one-to-one. The connecting posts 10 extend into the connecting slots 11 provided in the other half-partition 3.

[0020] The corners of the inner wall of the semi-partition 3 are rounded. The rounding reduces friction between the limiting groove 4 and the partition body.

[0021] The corner where the spacer body meets the outer surface of the mounting shaft 1 is rounded. The rounding reduces friction between the limiting groove 4 and the spacer body.

[0022] The two half-spacers 3 are provided with disassembly grooves 12 in the middle of the front and rear surfaces. When the two half-spacers 3 are difficult to separate, a flathead screwdriver can be inserted into the disassembly groove 12, and then a hammer or other tools can be used to tap them to make it easier to separate the two half-spacers 3.

[0023] A concealed groove 13 is provided on the outer side of the screw hole 7. The bolt 2 consists of a stud 201 and a nut 202, with the nut 202 set inside the concealed groove 13. The concealed groove 13 serves to accommodate the nut 202 and prevent the nut 202 from protruding from the semi-spacer 3.

[0024] Working principle: During installation, the two half-spacers 3 are placed in the limiting groove 4, and then the connecting post 10 and the connecting groove 11 are aligned. The connection of the connecting post 10 and the connecting groove 11 makes the two half-spacers 3 more tightly connected. Then, the bolt 2 is threaded into the screw hole 7, and then the bolt 2 is threaded through the through hole 9 and threaded into the screw groove 8. This completes the connection of the two half-spacers 3. During disassembly, the bolt 2 is unscrewed and removed, and the two half-spacers 3 are disassembled. In summary, by dividing the spacer body into two half-spacers 3 and connecting the two half-spacers 3 with bolt 2, the spacer body can be quickly installed into the limiting groove 4 on the mounting shaft 1. Installation is easy, and disassembly is also convenient.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
