Description

Technical Field

[0001] This utility model relates to speed reducers, and in particular to a speed reducer that is easy to adjust the installation angle. Background Technology

[0002] A speed reducer, also known as a gearbox, is a power transmission mechanism whose main function is to convert high-speed rotating power (such as motor output) into the required low-speed rotating power through a certain transmission ratio, while often increasing the output torque.

[0003] To adapt to different working environments, the speed reducer's installation angle is adjusted according to different equipment to reduce vibration and noise, improve transmission efficiency, and prevent premature wear. After calculating the correct installation angle, the operator installs the speed reducer, using its output shaft as a power source to drive the equipment in production operations. To ensure accurate connection between the speed reducer and the production equipment, the installation angle must be precisely adjusted during installation, and the speed reducer must be provided with stable support to ensure stable torque output.

[0004] To address the above issues, we propose a speed reducer that allows for easy adjustment of the installation angle. Utility Model Content

[0034] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example:

[0036] like Figures 1 to 3 As shown, a speed reducer with an adjustable installation angle includes a motor body 11 and a gearbox 12. A mounting base 13 is provided below the motor body 11, and the mounting base 13 has several mounting holes. Technicians can install the speed reducer with an adjustable installation angle onto the mounting platform by fixing the mounting base 13.

[0037] A base 14 is fixedly connected to the mounting base 13. A lead screw 15 is rotatably connected to the side of the base 14. A rotating mechanism is provided on the lead screw 15. The rotating mechanism is connected to the gearbox 12. The rotating mechanism drives the gearbox 12 to swing, thereby adjusting the motor body 11 and the gearbox 12 to the required installation angle.

[0038] The rotating mechanism includes a rotating block 16 and a dragging assembly. The specific connection method of the rotating mechanism is as follows: rotating seats 18 are symmetrically arranged at the upper end of the base 14. The rotating block 16 is rotatably connected to the rotating seat 18 through a pin. A connecting plate 19 is fixedly connected to the rotating block 16. The connecting plate 19 is connected to the dragging assembly. The dragging assembly is connected to the lead screw 15. The dragging assembly drags the rotating block 16, thereby causing the rotating block 16 to drive the reduction gearbox 12 to rotate, so as to adjust the installation angle of the reducer that is easy to adjust the installation angle.

[0039] The dragging assembly includes a dragging rod 17 and a movable seat 20. The movable seat 20 is threadedly connected to the lead screw 15 (the base 14 is provided with a limit rod on one side of the lead screw 15, which is not shown in the figure. The movable seat 20 is slidably connected to the limit rod, so that the movable seat 20 can only move horizontally left and right, and provides a certain support to the movable seat 20 to keep it in a horizontal state, thereby avoiding damage to the lead screw 15 during the adjustment of the inclination). The lower end of the dragging rod 17 is hinged to the upper end of the movable seat 20 by a pin, and the upper end of the dragging rod 17 is hinged to the connecting plate 19 by a pin.

[0040] Technicians can manually rotate or drive the lead screw 15 to rotate via a small motor, thereby causing the moving seat 20 to slide the lower end of the drag rod 17, which in turn drags the rotating block 16 and causes the rotating block 16 to rotate, thereby adjusting the inclination of the motor body 11 and the reduction gearbox 12.

[0041] After the technician adjusts the inclination of the motor body 11 and the gearbox 12 using the rotating block 16, it is necessary to lock the lead screw 15 to prevent it from rotating, thereby locking the inclination of the motor body 11 and the gearbox 12. Therefore, the base 14 is provided with a first locking component for locking the lead screw 15.

[0042] The first locking assembly includes a first threaded shaft 21 and a first stop block 22. The specific structure of the first locking assembly is as follows: The base 14 has a first locking groove 23 on the side away from the lead screw 15. The lead screw 15 includes a locking shaft 24, which is rotatably connected to the base 14, and the end of the locking shaft 24 extends into the first locking groove 23. The first stop block 22 is slidably connected to the first locking groove 23. The first threaded shaft 21 is rotatably connected to the first locking groove 23. The first stop block has a threaded groove 33, and the first threaded shaft 21 is threadedly connected to the threaded groove 33. There is a certain gap between the first threaded shaft 21 and the bottom of the threaded groove 33. Since the first threaded shaft 21 can only rotate within the first locking groove 23 and cannot move left or right, when the technician rotates the first threaded shaft 21, the first stop block 22 threadedly connected to the first threaded shaft 21 moves left or right.

[0043] The locking shaft 24 is fixedly connected to a stop plate 25. When the lead screw 15 rotates, the first stop block 22 does not contact the stop plate 25. After the technician adjusts the inclination of the motor body 11 and the gearbox 12, the first threaded shaft 21 is rotated to bring the first stop block 22 closer to the stop plate 25 until the first stop block 22 presses against the stop plate 25. The friction between the first stop block 22 and the stop plate 25 locks the lead screw 15, preventing it from rotating. This locks the inclination of the motor body 11 and the gearbox 12. Both the first stop block 22 and the stop plate 25 have several first friction ridges 26 distributed circumferentially to increase the friction between the first stop block 22 and the stop plate 25, further ensuring that the lead screw 15 cannot rotate in the locked state.

[0044] The tilted motor body 11 and the gearbox 12 require stable support to ensure a stable connection with the input shaft of the production equipment. The mounting base 13 has a support mechanism fixedly connected to the side away from the base 14 for supporting the motor body 11. The support mechanism includes an arc-shaped sleeve 27 and an arc-shaped sliding plate 28. The arc-shaped sleeve 27 is fixedly connected to the mounting base 13. The lower end of the arc-shaped sliding plate 28 is slidably connected to the arc-shaped sleeve 27. The upper end of the arc-shaped sliding plate 28 is fixedly connected to the motor body 11. The arc-shaped sleeve 27 is provided with a second locking component for locking the arc-shaped sliding plate 28.

[0045] When the gearbox 12 rotates with the rotating block 16, the arc-shaped sliding plate 28 slides within the arc-shaped sleeve 27 with the axis of the rotating block 16 as the rotation center. After the technician adjusts the inclination of the motor body 11 and the gearbox 12, the position of the arc-shaped sliding plate 28 is locked by the second locking component, thereby achieving the purpose of stably supporting the gearbox 12.

[0046] The second locking component includes a second abutment block 29 and a second threaded post 30. The inner wall of the arc-shaped sleeve 27 has a movable groove 31, and the side wall of the movable groove 31 has a threaded hole 34. The second threaded post 30 is threaded into the threaded hole 34. The second abutment block 29 is slidably connected to the movable groove 31. The second threaded post 30 is rotatably connected to the second abutment block 29. After the technician adjusts the inclination of the motor body 11 and the gearbox 12, the second threaded post 30 is rotated to bring the second abutment block 29 close to the arc-shaped slide plate 28 until it presses against the side of the arc-shaped slide plate 28, thereby locking the arc-shaped slide plate 28 by friction and preventing it from continuing to slide within the arc-shaped sleeve 27.

[0047] In addition, the sidewall of the arc-shaped sliding plate 28 and the second abutment block 29 are both provided with second friction ridges 32, thereby increasing the friction between the arc-shaped sliding plate 28 and the second abutment block 29. This ensures that after the second abutment block 29 locks the arc-shaped sliding plate 28, the arc-shaped sliding plate 28 can no longer slide within the arc-shaped sleeve 27, thereby achieving the purpose of stably supporting the motor body 11.

[0048] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
