A speed reducer with a high-stability gear

Abstract

This utility model relates to the field of speed reducer technology and discloses a speed reducer with a high-stability gear, including a base, a connecting motor, and the speed reducer. A placement seat is fixedly connected to one side of the upper surface of the base. A T-shaped disk is rotatably connected inside the placement seat. The upper surface of the T-shaped disk has circumferentially formed inclined grooves, and a slider is slidably connected to the inner wall of the inclined groove. This utility model drives the worm gear to rotate by starting the drive motor, which in turn drives the half-worm wheel to rotate, which in turn drives the T-shaped disk to rotate. Because a T-shaped block is installed on the slider inside the inclined groove, the slider can move within the inclined groove when the T-shaped disk rotates. This causes the slider to pull the T-shaped block to slide within the through groove, thereby causing the slider to drive the insertion rod on the fixed plate into the insertion hole on the motor base below the connecting motor. This achieves positioning of the connecting motor and avoids the problem of poor speed reducer stability caused by the connecting motor sliding on the placement seat.

Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, and more specifically, to a speed reducer with a highly stable gear. Background Technology

[0002] The gear reducer is an external meshing involute helical cylindrical gear reducer manufactured according to the national professional standard ZBJ19004. Gear reducers are widely used in East my country as the slewing mechanism of tower crane machinery, and are widely used in metallurgy, mining, hoisting, transportation, cement, construction, chemical, textile, printing and dyeing or pharmaceutical fields.

[0003] Currently available gear reducers on the market have the advantages of good reduction effect and ease of use. However, existing gear reducers have poor stability and may become loose or unstable after long-term use, affecting the use of the reducer. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a reducer with a high-stability gear, which has the advantage of positioning the connected motor and avoiding the poor stability of the reducer caused by the connected motor sliding on the mounting seat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reducer with a high-stability gear, comprising a base, a motor connecting the reducer, a placement seat fixedly connected to one side of the upper surface of the base, a T-shaped disk rotatably connected inside the placement seat, inclined grooves being formed circumferentially on the upper surface of the T-shaped disk, a slider being slidably connected to the inner wall of the inclined groove, a T-shaped block being mounted on the upper surface of the slider, through grooves being formed circumferentially on the upper surface of the placement seat, and the outer wall of the T-shaped block being slidably connected to the inner wall of the through groove. A fixing plate is fixedly connected to one side of the upper surface of the block, and a plug rod is fixedly connected to one side of each fixing plate. A semi-worm gear is fixedly connected to one side of the lower outer wall of the T-shaped disk. A drive motor is installed on the lower inner wall of the first placement seat. A worm is installed at the output end of the drive motor. One end of the worm is rotatably connected to one side of the inner wall of the first placement seat. One side of the worm meshes with the semi-worm gear. A motor seat is installed on the lower surface of the connecting motor. Insertion holes are opened circumferentially on the outer wall of the motor seat. The outer wall of the plug rod is engaged with the inner wall of the insertion hole.

[0006] As a preferred technical solution of the reducer with high stability gear of the present utility model, an electric push rod is installed on the other side of the upper surface of the base, and a second placement seat is installed at the output end of the electric push rod. A machine base is installed on the lower surface of the reducer, and the machine base is installed on the upper surface of the second placement seat.

[0007] As a preferred technical solution of the reducer with high stability gear of the present utility model, L-shaped frames are fixedly connected to both sides of the upper surface of the second mounting base, and screws are threaded to both sides of the surface of the L-shaped frame. A pressure plate is installed at the bottom end of the screw, and the lower surface of the pressure plate is in contact with the upper surface of the base.

[0008] As a preferred technical solution of the reducer with high stability gear of the present utility model, the lower surface of the second placement seat is fixedly connected to the four corners of the reducer, and the bottom end of the reducer is installed on the other side of the upper surface of the base.

[0009] As a preferred technical solution of the reducer with high stability gear of this utility model, the through groove has slots on both sides inside.

[0010] As a preferred technical solution of the present invention for a speed reducer with a high-stability gear, the output end of the connecting motor is installed on the input end of the speed reducer.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a drive motor to rotate a worm gear, which in turn rotates a semi-worm wheel, which in turn rotates a T-shaped disk. Because a T-shaped block is installed on the slider inside the inclined groove, the slider moves within the groove as the T-shaped disk rotates. This causes the slider to pull the T-shaped block through the slot, allowing the slider to drive the insert rod on the fixed plate into the insertion hole on the motor mount below the connecting motor. This achieves positioning of the connecting motor and prevents it from sliding on the mounting base, which could lead to poor stability of the reducer. Attached Figure Description

[0018] 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.

[0019] like Figures 1 to 4 As shown, this utility model provides a reducer with a high-stability gear, including a base 1, a motor 13 connecting to the reducer 18, a placement seat 2 fixedly connected to one side of the upper surface of the base 1, a T-shaped disk 3 rotatably connected inside the placement seat 2, inclined grooves 4 being formed around the upper surface of the T-shaped disk 3, a slider 5 slidably connected to the inner wall of the inclined grooves 4, a T-shaped block 6 mounted on the upper surface of the slider 5, through grooves 7 being formed around the upper surface of the placement seat 2, the outer wall of the T-shaped block 6 slidably connected to the inner wall of the through groove 7, and a fixed gear 18 on one side of the upper surface of the T-shaped block 6. A fixing plate 8 is connected, and a plug rod 9 is fixedly connected to one side of the fixing plate 8. A half worm gear 10 is fixedly connected to one side of the lower outer wall of the T-shaped disk 3. A drive motor 11 is installed on the lower inner wall of the placement seat 2. A worm 12 is installed at the output end of the drive motor 11. One end of the worm 12 is rotatably connected to one side of the inner wall of the placement seat 2. One side of the worm 12 meshes with the half worm gear 10. A motor seat 14 is installed on the lower surface of the motor 13. A plug hole 15 is opened in the circumference of the outer wall of the motor seat 14. The outer wall of the plug rod 9 is stuck in the inner wall of the plug hole 15.

[0020] By placing the connecting motor 13 on the placement seat 2, and then starting the drive motor 11 to drive the worm gear 12 to rotate, the worm gear 12 drives the half worm wheel 10 to rotate, which in turn drives the T-shaped disk 3 to rotate. Since the slider 5 inside the inclined groove 4 is equipped with a T-shaped block 6, when the T-shaped disk 3 rotates, the slider 5 can move in the inclined groove 4, thereby causing the slider 5 to pull the T-shaped block 6 to slide in the through groove 7. This allows the slider 5 to drive the insertion rod 9 on the fixing plate 8 to insert into the insertion hole 15 on the motor seat 1914 below the connecting motor 13, thus achieving the positioning of the connecting motor 13 and preventing the connecting motor 13 from sliding on the placement seat 2, which would cause poor stability of the reducer 18.

[0021] Among them, an electric push rod 16 is installed on the other side of the upper surface of the base 1, and a second placement seat 17 is installed at the output end of the electric push rod 16. A base 19 is installed on the lower surface of the reducer 18, and the base 19 is installed on the upper surface of the second placement seat 17. L-shaped frames 20 are fixedly connected to both sides of the upper surface of the second placement seat 17. Screws 21 are threaded to both sides of the surface of the L-shaped frame 20. A pressure plate 22 is installed at the bottom end of the screw 21, and the lower surface of the pressure plate 22 is in contact with the upper surface of the base 19.

[0022] Telescopic rods 23 are fixedly connected to the four corners of the lower surface of the second base 17, and the bottom end of the telescopic rods 23 is installed on the other side of the upper surface of the base 1.

[0023] By placing the reducer 18 on the upper surface of the second mounting base 17, the base 19 on the lower surface of the reducer 18 is inserted into the L-shaped frame 20. The bolt is rotated to move the pressure plate 22 downward, so that the pressure plate 22 presses against the upper surface of the base 19, positioning the reducer 18 on the base 19. Then, the electric push rod 16 is activated to move the second mounting base 17, so that the center of the input end of the reducer 18 is aligned with the center of the output end of the connected motor 13. The telescopic rod 23 makes the movement of the second mounting base 17 more stable.

[0024] The through groove 7 has slots on both sides inside; the output end of the motor 13 is installed on the input end of the reducer 18.

[0025] Working principle and usage process of this utility model:

[0026] When the device is needed, the connecting motor 13 is placed on the placement seat 2, and then the drive motor 11 is started to drive the worm gear 12 to rotate. The worm gear 12 drives the half-worm wheel 10 to rotate, which in turn drives the T-shaped disk 3 to rotate. Since the slider 5 inside the inclined groove 4 is equipped with a T-shaped block 6, the slider 5 can move in the inclined groove 4 when the T-shaped disk 3 rotates. This causes the slider 5 to pull the T-shaped block 6 to slide in the through groove 7, thereby causing the slider 5 to drive the insertion rod 9 on the fixing plate 8 to insert into the insertion hole 15 on the motor seat 1914 below the connecting motor 13. This achieves the positioning of the connecting motor 13 and avoids... The problem of poor stability of the reducer 18 caused by the sliding of the motor 13 on the first placement seat 2 is addressed by placing the reducer 18 on the upper surface of the second placement seat 17, so that the base 19 on the lower surface of the reducer 18 is inserted into the L-shaped frame 20, and rotating the bolt drives the pressure plate 22 to move downward, so that the pressure plate 22 presses on the upper surface of the base 19, thereby positioning the reducer 18 on the base 19. Then, the electric push rod 16 is activated to move the second placement seat 17, so that the center of the input end of the reducer 18 is aligned with the center of the output end of the motor 13. The extension rod 23 makes the movement of the second placement seat 17 more stable.
