Description

Technical Field

[0001] The utility model relates to the technical field of transmission gears, in particular to a highly efficient and stable transmission gear. Background Art

[0002] Transmission gears are mechanical components that rely on two or more meshing teeth to transmit power and motion. The basic principle is based on the meshing and disengagement of the teeth, achieving power conversion at different speeds, torques, and directions.

[0003] Prior art publication CN218670489U proposes a highly efficient and stable transmission gear comprising a gear body, an annular mounting base connected to each side of the gear body, and a screw threaded through each side of the annular mounting base. One end of the screw, located within the annular mounting base, is connected to a clamping plate, and the other end of the screw is connected to a rotating plate. Compared to the prior art, this utility model provides a secure connection between the gear body and the transmission shaft, preventing gear damage and improving safety.

[0004] When in use, this application mainly achieves a stable connection between the transmission gear and the transmission shaft by bringing the two clamping plates close to each other, thereby clamping the corresponding transmission shaft, thereby improving stability and safety. However, when installing the transmission gear on the transmission shaft, it is necessary to control the rotation of the turn plate and the screw, which takes a certain amount of time to install, thereby affecting the efficiency of the transmission gear installation. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an efficient and stable transmission gear so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A highly efficient and stable transmission gear comprises a transmission gear body and a transmission shaft body, a mounting hole being provided at the center of the face side of the transmission gear body, two key slots being provided on the circumferential side of the mounting hole, a limiting slot being provided on the inner side wall of the key slot, a number of springs being connected to the inner side wall of the limiting slot, a card frame being fixedly connected to the end of the spring, and a locking piece being provided on the transmission shaft body.

[0008] In a preferred example, the present invention can be further configured as follows: the locking member includes two clamping blocks, both of which are fixedly mounted on the outer circumference of the transmission shaft, and one side of the clamping block is fixedly connected to a clamping rod corresponding to the clamping frame.

[0009] In a preferred example, the present invention can be further configured as follows: the end portion of the clamping rod close to the transmission shaft is tilted.

[0010] In a preferred example, the present invention can be further configured as follows: the side of the clamping frame away from the spring is arc-shaped, and the curvature of the side of the clamping frame away from the spring is the same as the curvature of the outer peripheral side of the transmission shaft.

[0011] In a preferred example, the present invention can be further configured as follows: the transmission shaft is inserted into the mounting hole, and the clamping rod is inserted into the corresponding clamping frame.

[0012] In summary, the present invention has at least one of the following beneficial technical effects:

[0013] 1. This highly efficient and stable transmission gear, when in use, after the transmission gear body is sleeved on the transmission shaft body, the transmission gear body can be fixed on the transmission shaft body through the cooperation of the clamping frame and the locking member. In addition, the centrifugal force generated when the transmission gear body rotates further increases the locking force of the transmission gear body on the transmission shaft body, achieving the effect of enabling the transmission gear body to be quickly installed on the transmission shaft body while further improving the stability of the transmission gear body on the transmission shaft body when rotating;

[0014] 2. This efficient and stable transmission gear has an inclined end portion of the clamping rod near the transmission shaft. When the transmission gear body slides on the transmission shaft, the end portion of the clamping frame provided in the transmission gear body will preferentially contact the inclined surface provided at the end portion of the clamping rod. As the transmission gear body moves, the clamping frame will be pulled by the inclined surface, so that the side wall of the clamping frame gradually fits the transmission shaft. At the same time, the spring will also be gradually stretched, thereby achieving the effect of fixing the transmission gear body.

[0015] 3. This is an efficient and stable transmission gear, in which the side of the card frame away from the spring is arc-shaped, and the arc of the side of the card frame is the same as the curvature of the outer peripheral side of the transmission shaft, so that after the card frame is restricted by the clamping rod, the card frame can completely fit the transmission shaft, thereby increasing the friction between the card frame and the transmission shaft, and thereby increasing the axial stability of the transmission gear body on the transmission shaft.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1-4 The utility model discloses an efficient and stable transmission gear, including a transmission gear body 1 and a transmission shaft body 2. A mounting hole 3 is opened at the center of the surface side of the transmission gear body 1, and two key grooves 4 are opened on the circumferential side of the mounting hole 3. A limiting groove 5 is also opened on the inner side wall of the key groove 4. A number of springs 6 are connected to the inner side wall of the limiting groove 5. The end of the spring 6 is fixedly connected to a card frame 7, and a locking piece 8 is provided on the transmission shaft body 2.

[0025] When the gear wheel 1 is in the locked position, the locking member 8 is pressed against the locking member 8, and the locking member 8 is pressed against the locking member 8, thereby preventing the gear wheel 1 from sliding into the locked position.

[0026] In a further preferred embodiment of the present invention, Figure 1-3As shown, the locking member 8 includes two clamping blocks 9 , which are fixedly mounted on the outer circumference of the transmission shaft 2 , and one side of the clamping block 9 is fixedly connected to a clamping rod 10 corresponding to the clamping frame 7 .

[0027] In this embodiment, the clamping block 9 is installed on the outer peripheral side of the transmission shaft body 2, and the clamping frame 7 is connected to the side of the clamping block 9. When the transmission gear body 1 is sleeved on the transmission shaft body 2 and slides, the clamping frame 7 will gradually be sleeved on the clamping rod 10, so that the clamping frame 7 is limited to the clamping rod 10. The inner side wall of the clamping frame 7 is fitted with the side of the clamping rod 10 through the pulling of the reaction force of the spring 6, thereby increasing the friction between the clamping frame 7 and the clamping rod 10, and then improving the stability of the connection between the clamping frame 7 and the clamping rod 10. When the transmission gear body 1 rotates at high speed, the centrifugal force generated will cooperate with the reaction force of the spring 6 to further pull the clamping frame 7, thereby further increasing the stress after the clamping frame 7 and the clamping rod 10 are fitted, and further increasing the stability of the transmission gear body 1 installed on the shaft body.

[0028] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the end portion of the clamping rod 10 close to the transmission shaft 2 is tilted.

[0029] In this embodiment, the end of the card rod 10 close to the transmission shaft body 2 is inclined. When the transmission gear sleeve slides on the transmission shaft body 2, the end of the card frame 7 set in the transmission gear will preferentially contact the inclined surface set at the end of the card rod 10, and then as the transmission gear body 1 moves, the card frame 7 will be pulled through the inclined surface, so that the side walls of the card frame 7 gradually fit the transmission shaft body 2, and at the same time, the spring 6 will also be gradually stretched, thereby achieving the effect of fixing the transmission gear body 1.

[0030] In a further preferred embodiment of the present invention, Figure 3 As shown, the side of the clamping frame 7 away from the spring 6 is arranged in an arc shape, and the curvature of the side of the clamping frame 7 away from the spring 6 is the same as the curvature of the outer peripheral side of the transmission shaft body 2.

[0031] In this embodiment, the side of the clamping frame 7 away from the spring 6 is arc-shaped, and the arc-shaped side of the clamping frame 7 is the same as the curvature of the outer peripheral side of the transmission shaft 2, so that after the clamping frame 7 is limited by the clamping rod 10, the clamping frame 7 can completely fit the transmission shaft 2, thereby increasing the friction between the clamping frame 7 and the transmission shaft 2, and thereby increasing the axial stability of the transmission gear body 1 on the transmission shaft 2.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, the transmission shaft 2 is inserted into the mounting hole 3 , and the clamping rod 10 is inserted into the clamping frame 7 .

[0033] In this embodiment, the transmission gear body 1 is sleeved on the transmission shaft body 2, and then the clamping rod 10 is gradually aligned with the clamping frame 7, and finally the clamping frame 7 completely wraps the clamping rod 10, thereby completing the installation of the transmission gear body 1 and achieving a quick installation effect.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
