Description

Technical Field

[0001] This utility model belongs to the field of gears, and relates to a gear, and more particularly to a gear that is easy to disassemble. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. As the most widely used transmission structure, gears are mainly used to transmit force between different shafts.

[0003] For example, the gear with patent number 201220754468.6 includes a gear body and a shaft hole. The gear body includes a large half-gear and a small half-gear. The large half-gear is provided with a groove, and the small half-gear is provided with a protrusion. The large half-gear and the small half-gear are connected through the groove and the protrusion.

[0004] Although the aforementioned patent solves the disassembly difficulties caused by the integral casting of the gear body, the slots and protrusions can only prevent the large and small half-gears from detaching from the gear shaft in the radial direction. However, since the large and small half-gears have degrees of freedom in the axial direction, and the gear may move axially on the gear shaft, the small half-gear may misalign with the large half-gear or even fall off when the gear shaft drives the gear to rotate. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a gear that prevents accidental loosening during operation and is easy to disassemble.

[0006] This utility model can be achieved through the following technical solution: a gear that is easy to disassemble, including a gear body, an installation groove is provided on the gear body, a fixing part is inserted into the installation groove, a guide groove is provided on the installation groove, a guide part is provided on the fixing part, a slot is provided in the guide groove, and a connecting block is installed in the guide part.

[0007] In the aforementioned easily detachable gear, a fixing groove is provided on the fixing part, a push rod is inserted into the fixing groove, and a pushing part is provided on the connecting block, with the push rod contacting the pushing part.

[0008] In the aforementioned easily detachable gear, a spring is installed between the guide groove and the connecting block.

[0009] In the aforementioned easily disassembled gear, the fixing part has a countersunk screw hole on the side away from the fixing groove, and a countersunk bolt is inserted into the countersunk screw hole. The push rod has a connecting hole, and the countersunk bolt is inserted into the connecting hole.

[0010] In the aforementioned easily detachable gear, a first inclined surface is provided above the pushing part, and a second inclined surface is provided at the bottom of the pushing rod.

[0011] Compared with the prior art, the advantages of this utility model are: the addition of a connecting block and a slot, which together achieve a fixed connection between the fixing part and the gear body; the addition of a guide part and a guide groove, which allows the gear to be radially mounted on the gear shaft for easy assembly; and the connection between the fixing part and the gear body, together with the connecting block and the slot, prevents the gear from falling off due to axial movement.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 6 As shown, the present invention can be achieved through the following embodiments: a gear that is easy to disassemble includes a gear body 1, a mounting groove 11 is provided on the gear body 1, a fixing part 2 is inserted into the mounting groove 11, a guide groove 12 is provided on the mounting groove 11, a guide part 21 is provided on the fixing part 2, a slot 13 is provided in the guide groove 12, and a connecting block 3 is installed in the guide part 21.

[0015] The fixing part 2 is inserted into the mounting groove 11 to complete the gear body 1, so that the gear can be disassembled radially from the gear shaft, improving disassembly efficiency. The guide groove 12 and the guide block cooperate to guide the fixing part 2 into the mounting groove 11, and at the same time, the cooperation of the guide groove 12 and the guide block restricts the axial movement of the fixing part 2 relative to the gear body 1. The slot 13 and the connecting block 3 cooperate to increase the contact area between the fixing part 2 and the gear body 1 at the mounting groove 11, and together with the guide groove 12 and the guide block, restrict the axial movement of the fixing part 2 relative to the gear body 1 and prevent radial displacement of the fixing part 2.

[0016] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a fixing groove 22 is provided on the fixing part 2, and a push rod 4 is inserted into the fixing groove 22. A pushing part 31 is provided on the connecting block 3, and the push rod 4 contacts the pushing part 31. The push rod 4 is inserted into the fixing groove 22, and the pushing rod 4 presses the pushing part 31 on the connecting block 3, pushing the connecting block 3 into the slot 13, thereby realizing the fixed connection between the fixing part 2 and the gear body 1.

[0017] like Figure 3 As shown, a spring 5 is installed between the guide groove 12 and the connecting block 3. The spring 5 is used to push the connecting block 3 out of the slot 13 after the push rod 4 is moved out of the fixing groove 22, thereby releasing the connection between the fixing part 2 and the gear body 1 and improving the disassembly efficiency of the gear body 1.

[0018] like Figures 2 to 5 As shown, the fixing part 2 has a countersunk screw hole 23 on the side away from the fixing groove 22, and a countersunk bolt 6 is inserted into the countersunk screw hole 23. The push rod 4 has a connecting hole 41, and the countersunk bolt 6 is inserted into the connecting hole 41. The countersunk bolt 6 is used to insert into the countersunk screw hole 23 of the fixing part 2 and the connecting hole 41 of the push rod 4, thereby fixing the fixing part 2 and the push rod 4 together. This allows the connecting block 3 to be stably engaged in the slot 13 under the push of the push rod 4, ensuring the connection between the fixing part 2 and the gear body 1.

[0019] like Figure 5 and Figure 6 As shown, a first inclined surface 311 is provided above the pushing part 31, and a second inclined surface 42 is provided at the bottom of the pushing rod 4. The first inclined surface 311 and the second inclined surface 42 are in contact with each other, ensuring that when the pushing rod 4 is inserted into the fixing groove 22, it pushes the connecting block 3 laterally into the slot 13, thereby improving assembly efficiency.

[0020] The working principle of this utility model is as follows: When it is necessary to assemble the gear body 1 onto the gear shaft, the gear body 1 is placed on the shaft, and then the fixing part 2 is inserted into the mounting groove 11. Then, the push rod 4 is inserted into the fixing groove 22. The inclined surface 311 on the push rod 4 and the inclined surface 42 on the pushing part 31 contact each other, so that the push rod 4 pushes the connecting block 3 into the slot 13. Finally, the countersunk bolt 6 is inserted into the connecting hole 41 and the countersunk screw hole 23 to fix the push rod 4 and the fixing part 2 together, so that the connecting block 3 is fixed to the slot 13, preventing the fixing part 2 from falling off the mounting groove 11 when the gear body 1 rotates.

[0021] When disassembly is required, unscrew the countersunk bolt 6, pull the push rod 4 out of the fixing groove 22 using the handle on the push rod 4, the spring 5 pushes the connecting block 3 away from the slot 13, and finally the fixing part 2 is taken away from the mounting groove 11, so that the gear body 1 can be removed from the gear shaft.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
