Description

Technical Field

[0001] The utility model relates to the technical field of angle adjustment motors, in particular to an angle adjustment motor with an equal force screw. Background Art

[0002] See also Figure 1 During the use of traditional angle adjustment motors, the disordered position of the screw holes will cause uneven force on the reduction gear box cover during installation, which will lead to poor stability, increased wear and displacement between components during motor operation. Under long-term working conditions, the life of the motor will be seriously damaged. The unevenly stressed screws may have the risk of falling off, and in severe cases, cracks and fissures may appear on the reduction gear box body and cover, making it difficult for the motor to meet the expected standards. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide an equal-force screw angle adjustment motor in response to the above-mentioned shortcomings caused by the disordered positions of the screw holes in the traditional angle adjustment motor, which improves the screw installation position, makes the screw force uniform, and stabilizes the motor operation.

[0004] The technical problems to be solved by the present invention can be achieved through the following technical solutions:

[0005] The transmission gear of the present invention is a gear shifting mechanism, and the transmission gear of the present invention is a gear shifting mechanism, and the transmission gear of the present invention is a gear shifting mechanism.

[0006] In a preferred embodiment of the present invention, the first screw is located above the meshing point between the worm and the double gear; the second screw is located above the connection between the reduction gear box body and the motor casing, and the third screw is located at the outermost connection between the reduction gear box cover and the reduction gear box body.

[0007] By adopting the above technical solution, the present invention optimizes the position of the screw holes, integrates the position of the double gears and hollow sleeves at the input end, and adjusts the force uniformly on the screw holes. This effectively reduces the risk of vibration from the motor and reducer affecting the life of the reducer cover and reducer body, reduces the effect of screw torque on the reducer cover and reducer body, simplifies the assembly process, reduces the residual stress of each screw during assembly, reduces the wear and tear of the reducer cover and reducer body, and improves the life of the motor. After assembly with the frame, it can effectively prevent interference with the reducer cover and reducer body caused by external components such as the frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0012] See also Figure 2 and Figure 3 The figure shows an equal-force screw angle adjustment motor, which includes a motor 100 and a reduction gear 200. A double gear, an output gear, and a worm are provided in the reduction gear 200. The worm is fixed on the motor output shaft in the motor 100 and extends into the reduction gear 200. The worm transmits mechanical energy by meshing with the double gear and the output gear in sequence.

[0013] The reduction gearbox 200 includes a reduction gearbox body 210 and a reduction gearbox cover 220 . The reduction gearbox cover 220 is mounted on the reduction gearbox body 210 via a hollow insert 310 and three screws.

[0014] The characteristics of the present utility model are: the three screws are divided into a first screw 320, a second screw 330 and a third screw 340, among which the first screw 320 is located above the meshing point of the worm and the double gear, so as to ensure the stability of the hollow sleeve 310 when connected with the external component and the reduction box body 210 is connected with the housing 110 of the motor 100; the second screw is located above the connection between the reduction box body 210 and the housing 110 of the motor 100, so as to ensure the stability of the motor 100 itself when decelerating and increasing the torque; the third screw 340 is located at the outermost connection between the reduction box cover 220 and the reduction box body 210, so as to balance the torque generated by the first screw 320 and the second screw 330.

[0015] The first, second, and third screws 320, 330, and 340 are equidistant from the pin 410 of the dual gear and have equal lever arms. This generates equal torque, improving the operational stability of the motor 100 and extending its service life. It also reduces the impact of external components during assembly with the frame, ensuring optimal performance of the motor 100. The optimal positioning of the first, second, and third screws 320, 330, and 340 effectively controls the effects of motor 100 vibration and balances uneven forces across the components.
