[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, this utility model provides a gear stamping part that is easy to install, mainly used for power-driven gears. Its structure mainly includes a gear part 1, a bearing part 2, a washer 3, and a locking part 4. During assembly, after the gear part 1 is connected to the bearing part 2, it can be further fixed by the washer 3 and the locking part 4 to prevent the gear part 1 and the bearing part 2 from becoming loose.

[0026] When gear component 1 is connected to bearing component 2, gear component 1 is fitted onto the outside of bearing component 2 and fixed in a designated position. Gear component 1 has a first opening 101 for assembling bearing component 2 and several second openings 102 for easy locking. Both the first and second openings 101 extend through both sides of gear component 1. The first opening 101 is located in the middle of gear component 1 and is coaxial with it. The second openings 102 are circumferentially distributed around the first openings 101 and are equidistant. A number of slots 103, equal to the number of second openings 102, are provided on one side of gear component 1. These slots 103 are located between the first and second openings 101 and communicate with both the first and second openings 102. This structure facilitates assembly with bearing component 2 and creates a more stable structure after assembly.

[0027] Correspondingly, the bearing piece 2 is inserted into the first opening part 101, and a plurality of protruding extension parts 201 are arranged on the outer side of the bearing piece 2 and fixed in the clamping grooves 103. The number and position of the extension parts 201 correspond to the clamping grooves 103. The end of the extension part 201 away from the bearing piece 2 is provided with a clamping strip 202 for inserting into the corresponding second opening part 102. The end of the clamping strip 202 away from the extension part 201 is provided with a locking part 203 for locking. When the gear piece 1 and the bearing piece 2 are assembled, when the extension part 201 is clamped and fixed in the clamping groove 103, the clamping strip 202 is inserted into the corresponding second opening part 102, and then the locking part 203 is locked and fixed on the side of the gear piece 1 away from the clamping groove 103. At this time, the locking part 203 can be fixed by means of a hook, which is also convenient for users to disassemble.

[0028] In order to further strengthen the stability between the gear piece 1 and the bearing piece 2, and effectively prevent the clamping strip 202 from falling off from the second opening part 102, on one side of the gear piece 1, the side of the gear piece 1 provided with the clamping groove 103 is provided with a recess 105. The recess 105 is coaxially arranged with the gear piece 1, and the first opening part 101, the second opening part 102 and the clamping groove 103 are all arranged inside the recess 105. Correspondingly, the outer side of the bearing piece 2 is sleeved with a gasket 3 arranged coaxially. The gasket 3 matches the recess 105. During installation, the gasket 3 is installed in the recess 105 and locked and fixed by a plurality of locking pieces 4. It should be noted that the gasket 3 and the bearing piece 2 can be integrally connected or separated. Both structures do not affect the fixing of the gasket in the recess 105.

[0029] On the other side of the gear piece 1, the side of the gear piece 1 away from the clamping groove 103 is provided with a plurality of locking grooves 106 corresponding to the number of the second opening part 102. The locking grooves 106 are arranged on the side corresponding to the second opening part 102 and communicated with the second opening part 102. The locking part 203 is arranged in the corresponding locking groove 106 and fixed, which avoids the collision of the protruding locking part 203 after locking, causing displacement or loosening.

[0030] The outer edge of the gear piece 1 is provided with a gear tooth 104, which is distributed along the circumferential direction of the gear piece 1 to realize the transmission function of the gear. One end of the bearing piece 2 is provided with a connecting part 204 for installation and fixation, which is used for installation and fixation with other components and drives the gear piece 1 to transmit.

[0031] In the installation, the bearing part 2 is inserted into the first opening part 101 of the gear part 1 until it is completely inside the gear part 1. The extension part 201 outside the bearing part 2 is aligned with the clamping groove 103 of the gear part 1, and the bearing part 2 is pushed so that the extension part 201 is clamped into the clamping groove 103. The clamping strip 202 at the end of each extension part 201 is inserted from the corresponding second opening part 102 until the clamping strip 202 is completely clamped into the clamping groove 103, and at the same time, the locking part 203 is locked and fixed in the locking groove 106. The gasket 3 is sleeved on the outside of the bearing part 2 and placed in the recess 105 of the gear part 1. The gasket 3 is locked in the recess 105 using the locking part 4, and the installation of the entire gear stamping part is completed.

[0032] Compared with the prior art, the gear stamping part provided by the technical scheme simplifies the installation steps between the gear part 1 and the bearing part 2 by providing the second opening part 102 and the clamping strip 202 for plug-in installation on the gear part 1 and the bearing part 2, limiting and fixing through the clamping groove 103 and locking and fixing through the locking part 203, avoiding complicated operations, and through the multiple fixing structures, not only the connection strength between the gear part 1 and the bearing part 2 is enhanced, but also the stability of the overall structure is improved.

[0033] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application, and any reference signs in the claims should not be regarded as limiting the claims.
