Description

Technical Field

[0001] This utility model relates to the field of speed reduction technology, and in particular to a three-stage self-locking speed reducer. Background Technology

[0002] A speed reducer is a device used to change the output torque and speed of a power mechanism. It can improve the efficiency of an engine and the stability of traction, and is usually installed at the power output end of a power device. Its core function is to reduce the input speed while significantly increasing the output torque.

[0003] Currently available speed reducers have complex structures, large sizes, and complicated installation and disassembly operations. They cannot maintain self-locking while performing multi-stage speed regulation, resulting in significant installation limitations and very limited functionality. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the reducers on the market are complex in structure, large in size, and complicated in installation and disassembly. They cannot maintain self-locking while performing multi-stage speed regulation, resulting in large installation restrictions and very limited functionality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a three-stage self-locking reducer, including a side end cover, a base and a drive motor. The bottom of the base has a bottom mounting seat with a downward protrusion. The lower surface of the bottom mounting seat has four downward protruding lateral stabilizing frames. The inner side of the lateral stabilizing frame has an integral inner locking buckle. The outer side of the drive motor is provided with lateral mounting grooves corresponding to the lateral stabilizing frames. An output shaft, a spur gear, a planetary gear, an internal gear ring and a linkage gear are provided between the side end cover and the base.

[0006] The upper end of the lateral mounting tooth groove is provided with a top mounting groove.

[0007] The drive shaft at the upper end of the drive motor is axially fixed with a worm gear that meshes with a linkage gear. The linkage gear includes a worm wheel section that meshes with the worm gear and a spur gear section that meshes with a spur gear.

[0008] Bearings are provided between the spur gear and the base, between the spur gear and the internal gear ring, and between the planetary gear and the internal gear ring.

[0009] The worm gear section and the spur gear section are fixedly connected by a connecting shaft.

[0010] The side end cap is symmetrically provided with side guide holes, and the planetary gear sidewall has a guide shaft that cooperates with the side guide holes.

[0011] The beneficial effects of this utility model are: (1) The three-stage self-locking reducer of this utility model can withstand large torque and self-lock after three-stage reduction, which greatly improves its functionality and practicality. (2) By cooperating with the bottom mounting base and the lateral stabilizing frame at the bottom of the base, it can be quickly snapped and fixed on the lateral mounting toothed groove on the outside of the drive motor, making it easier to install and operate. (3) The entire reducer has a compact structure, small size, small space occupation, and is easy to assemble. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model.

[0014] Figure 2 This is a partial schematic diagram of the drive motor assembly end in this utility model. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Figure 1 and Figure 2 The three-stage self-locking reducer shown includes a side end cover 1, a base 2, and a drive motor 3. The bottom of the base 2 has a bottom mounting seat 4 that protrudes downwards. The lower surface of the bottom mounting seat 4 has four downwardly protruding lateral stabilizing frames 5. The inner side of the lateral stabilizing frame 5 has an integrated inner latch 6. The outer side of the drive motor 3 has lateral mounting grooves 7 corresponding to the positions of the lateral stabilizing frames 5. An output shaft 8, a spur gear 9, a planetary gear 10, an internal gear ring 11, and a linkage gear are arranged between the side end cover 1 and the base 2.

[0018] The upper end of the side mounting tooth groove 7 is provided with a top mounting groove 12.

[0019] The base 2 is engaged with the drive motor 3 by the inner latch 6 on the inner side of the lateral stabilizing frame 5 through the top mounting slot 12 and then into the lateral mounting tooth groove 7. At this time, the inner latch 6 and the lateral mounting tooth groove 7 engage and limit the movement. The inner arc surface of the lateral stabilizing frame 5 can provide lateral limiting capability for the drive motor 3.

[0020] To facilitate the linkage drive, a worm gear 13 that meshes with the linkage gear is axially fixed on the upper drive shaft of the drive motor 3. The linkage gear includes a worm wheel section 14 that meshes with the worm gear 13 and a spur gear section 15 that meshes with the spur gear 9.

[0021] The drive motor 3 drives the worm gear section 14 through the worm 13, which synchronously drives the spur gear section 15 to rotate. The spur gear section 15 drives the spur gear 9, and the eccentric shaft on the right side of the spur gear 9 drives the planetary gear 10 to move on the internal gear ring 11. Then, the planetary gear 10 drives the side end cover 1 to rotate, and the side end cover 1 drives the output shaft 8 to rotate at high torque and low speed.

[0022] To reduce assembly friction, bearings 16 are provided between the spur gear 9 and the base 2, between the spur gear 9 and the internal gear ring 11, and between the planetary gear 10 and the internal gear ring 11.

[0023] To facilitate axial fixed assembly, the worm gear section 14 and the spur gear section 15 are fixedly connected by a connecting shaft 17.

[0024] To facilitate eccentric guidance, symmetrical side guide holes 18 are provided on the side end cover 1, and the planetary gear 10 has a guide shaft 19 on its side wall that cooperates with the side guide holes 18.

[0025] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
