Description

Technical Field

[0001] This utility model relates to the field of speed reducers, and in particular to a hand-cranked self-rotating speed reducer. Background Technology

[0002] Currently, speed reducers, as core components in the field of mechanical transmission, are widely used in various industrial equipment to reduce speed and increase torque. Traditional speed reducers are mostly driven by motors or hydraulics.

[0003] Related technology can be found in Chinese Patent No. CN222526807U, which discloses a bearing-type micro RV reducer, including a cycloidal housing, an eccentric shaft, an input flange, a first cycloidal wheel, a second cycloidal wheel, cycloidal needle rollers, pins, housing locking screws, and an output integral cross bearing. The output integral cross bearing includes an outer ring, an inner ring, cross rollers, a plug, and a plug screw. This utility model directly uses an integral spring-loaded cross roller bearing as the output mechanism, which can reduce the diameter of the reducer and make assembly easier. Furthermore, the outer ring of the cross bearing is set as a whole, with no exposed screws on the outside, which greatly improves the aesthetics of the reducer and also shortens the length of the reducer, reducing production costs and weight. In addition, the eccentric part of the eccentric shaft and the two cycloidal wheels can each use needle roller bearings without inner and outer rings and cages, which can further reduce the diameter of the reducer.

[0004] Regarding the aforementioned technologies, after the reducer is assembled with the equipment to be installed, its positional relationship with the equipment is relatively fixed. This results in a fixed operating angle between the reducer and the equipment during use. When the angle of the reducer installation position needs to be adjusted, there are limitations, which is not conducive to improving the convenience and applicability of the reducer. Utility Model Content

[0005] To improve the convenience and applicability of the reducer, this application provides a hand-cranked self-rotating reducer.

[0006] This application provides a hand-cranked self-rotating speed reducer, which adopts the following technical solution: A hand-cranked self-rotating speed reducer includes a speed reducer housing and a support frame. The speed reducer housing is mounted on the support frame. A worm gear is fixedly connected to one side of the speed reducer housing along its length. The worm gear is rotatably connected to the support frame. A worm gear meshing with the worm gear and a fixing member for supporting the worm gear are provided between the speed reducer housing and the support frame. A locking assembly for fixing the speed reducer housing is provided between the speed reducer housing and the support frame.

[0007] By adopting the above technical solution, the bracket supports the gearbox. When the user rotates the worm, the worm drives the worm wheel to rotate vertically, and the worm wheel drives the gearbox to rotate vertically, thereby adjusting the gearbox to the angle required for connection with external equipment. The locking component fixes the adjusted angle of the gearbox, so that the reducer can be stably connected to external equipment for operation, which is conducive to improving the convenience and applicability of the reducer.

[0008] Optionally, a fixing plate one is fixedly provided on the side of the worm gear near the bracket, and a fixing plate two is fixedly provided on the side of the worm gear away from the fixing plate one. A rotating shaft is coaxially fixedly connected to the fixing plate one, and the worm gear is rotatably connected to the bracket through the rotating shaft. The fixing plate one, the fixing plate two, and the worm gear are all provided with several threaded holes along the circumference. The same threaded hole passes through the fixing plate one and the two worm gears on the fixing plate. A bolt is provided between the fixing plate one and the gearbox body. The bolt passes through the fixing plate one, the worm gear, and the fixing plate two in sequence and is inserted into the gearbox body, and is threadedly connected to the fixing plate one and the gearbox body.

[0009] By adopting the above technical solution, when the worm gear rotates vertically, it drives the first fixed plate and the second fixed plate to rotate vertically together. The bracket supports the first fixed plate through the rotating shaft, and in turn supports the worm gear and the second fixed plate. The gearbox is connected to the second fixed plate through bolts. The second fixed plate is coaxially fixedly connected to the worm gear, the second fixed plate, and the rotating shaft. When the gearbox rotates, the bracket supports the gearbox through the rotating shaft. The first fixed plate and the second fixed plate leave a certain gap between the lower sides of the worm gear and the gearbox and the bracket. The gap accommodates the worm and provides rotation space for the worm, which helps to improve the stability of the reducer rotation.

[0010] Optionally, the bracket includes two mounting plates and a crossbeam. The two mounting plates are parallel to each other, the crossbeam is located between the two mounting plates and its two ends are fixedly connected to the two mounting plates respectively, the gearbox is located between the two mounting plates, and the rotating shaft is rotatably connected to the mounting plate on the same side.

[0011] By adopting the above technical solution, the bracket supports the rotating shaft through the mounting plate, and the two mounting plates work together to clamp and fix the gearbox body. The crossbeam helps to improve the structural stability between the two mounting plates.

[0012] Optionally, the fixing component includes several limiting plates, which are fixedly connected to the side of the mounting plate near the worm gear and are arranged along the width direction of the mounting plate. The worm passes through the limiting plates and is rotatably connected to the limiting plates.

[0013] By adopting the above technical solution, the mounting plate supports and fixes the limiting plate, and several limiting plates cooperate to support and limit the worm gear, thereby enabling the mounting plate to support and limit the worm gear, which helps to improve the stability of the worm gear during rotation.

[0014] Optionally, the locking assembly includes an impeller and a threaded clamping rod. The impeller is sleeved on the outside of the second fixed plate and is coaxially and fixedly connected to the second fixed plate. The impeller has an arc-shaped hole in the circumferential direction. The threaded clamping rod passes through the mounting plate and the arc-shaped hole in sequence and is threadedly connected to the mounting plate. An abutment plate is fixedly provided at one end of the threaded clamping rod that passes through the arc-shaped plate.

[0015] By adopting the above technical solution, the second fixing plate supports and fixes the impeller. When the second fixing plate rotates, it drives the impeller to rotate vertically and rotates the threaded clamping rod in the tightening direction. The arc-shaped hole supports the threaded clamping rod, and the abutment rod cooperates with the impeller to fix the impeller through friction, thereby fixing the second fixing plate and finally fixing the gearbox body, which helps to improve the ease of operation of the device.

[0016] Optionally, the threaded clamping rod includes a threaded rod and a gripping rod. The gripping rod is located outside the mounting plate, the threaded rod passes through the mounting plate and is threadedly connected to the mounting plate, and the side of the threaded rod facing away from the gearbox body is vertically fixedly connected to the gripping rod.

[0017] By adopting the above technical solution, the operator can rotate the threaded rod by turning the handle, which saves the operator's strength and improves the ease of operation of the device.

[0018] Optionally, one end of the worm gear is coaxially fixedly connected to a ring, and a rocker arm parallel to the worm gear is fixedly connected to the ring.

[0019] By adopting the above technical solution, the operator can rotate the rocker arm to drive the worm gear to rotate through the ring, which saves the operator time and effort when rotating the worm gear and improves the convenience of operating the device.

[0020] Optionally, the upper ends of the worm gear, fixed plate one, and fixed plate two are all flush with the upper surface of the gearbox, and a disc is detachably connected to the upper surface of the reducer.

[0021] By adopting the above technical solution, the external agricultural machinery is connected to the gearbox via a disc. The worm gear, fixed plate one, and fixed plate two all avoid the disc, providing installation space for the connection between the external agricultural machinery and the gearbox.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The bracket supports the gearbox. When the user rotates the worm, the worm drives the worm wheel to rotate vertically, and the worm wheel drives the gearbox to rotate vertically. This adjusts the gearbox to the angle required for connection with external equipment. The locking assembly fixes the adjusted angle of the gearbox, allowing the reducer to be stably connected to external equipment for operation, which improves the convenience and applicability of the reducer. 2. When the worm gear rotates vertically, it drives fixed plate one and fixed plate two to rotate vertically together. The bracket supports fixed plate one through the rotating shaft, and in turn supports the worm gear and fixed plate two. The gearbox is connected to fixed plate two through bolts. Fixed plate two is coaxially fixedly connected to the worm gear, fixed plate two and rotating shaft. When the gearbox rotates, the bracket supports the gearbox through the rotating shaft. Fixed plate one and fixed plate two leave a certain gap between the lower sides of the worm gear and the gearbox and bracket. The gap accommodates the worm and provides rotation space for the worm, which helps to improve the stability of the reducer rotation. 3. The bracket supports the rotating shaft through the mounting plate. The two mounting plates work together to clamp and fix the gearbox body. The crossbeam helps to improve the structural stability between the two mounting plates. Attached Figure Description

Detailed Implementation

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a hand-cranked self-rotating speed reducer. Example

[0029] Reference Figure 1 A hand-cranked self-rotating speed reducer includes a speed reducer housing 1 and a bracket 2. The speed reducer is mounted on the bracket 2. The bracket 2 includes two mounting plates 21 and a crossbeam 22. The crossbeam 22 is located between the two mounting plates 21, and both ends of the crossbeam 22 are fixedly connected to the two mounting plates 21, thereby fixing the two mounting plates 21. The speed reducer housing 1 is located between the two mounting plates 21. The mounting plates 21 support the speed reducer housing 1, which helps to improve the stability of the support of the mounting plates 21 and the working stability of the speed reducer housing 1.

[0030] Reference Figure 1 and Figure 2A worm gear 3 is fixedly installed on one side of the gearbox 1 along its length. A fixing plate 5 is fixedly installed coaxially on the side of the worm gear 3 near the mounting plate 21, and a fixing plate 6 is fixedly installed coaxially on the other side. The fixing plate 6 and the gearbox 1 are fixedly connected. A rotating shaft 52 is coaxially connected to the fixing plate 5. The rotating shaft 52 passes through the mounting plate 21 and is rotatably connected to the mounting plate 21, so that the fixing plate 5 can rotate vertically. The side of the gearbox 1 away from the worm gear 3 is rotatably connected to the corresponding mounting plate 21, thereby allowing the gearbox 1 to rotate vertically.

[0031] Reference Figure 2 and Figure 3 The first fixing plate 5, the second fixing plate 6, and the worm gear 3 are all provided with several threaded holes along the circumference. The threaded holes on the first fixing plate 5, the second fixing plate 6, and the worm gear 3 are interconnected. Bolts 51 are provided in the threaded holes. The bolts 51 pass through the first fixing plate 5, the worm gear 3, and the second fixing plate 6 in sequence and are inserted into the gearbox 1 and threadedly connected to the first fixing plate 5 and the gearbox 1 to realize the connection between the second fixing plate 6 and the gearbox 1.

[0032] Reference Figure 1 and Figure 2 A worm 4 that meshes with a worm gear 3 is provided between the gearbox 1 and the mounting plate 21. The mounting plate 21 is provided with a fixing component for fixing the worm 4. The fixing component includes multiple limiting plates 211, which are distributed along the width direction of the mounting plate 21. The worm 4 passes through the limiting plates 211 in sequence and is rotatably connected to the limiting plates 211. The limiting plates 211 support and limit the worm 4. Fixing plate 5 and fixing plate 6 provide installation and rotation space for the worm 4, which helps to improve the stability of the worm 4 when rotating.

[0033] Reference Figure 1 and Figure 2 A ring 41 is fixedly connected to the end of the worm gear 4 away from the gearbox 1. A rocker arm 42 parallel to the worm gear 4 is fixedly connected to the side of the ring 41 away from the worm gear 4. The rocker arm 42 is easy for the operator to hold and facilitates the operator to rotate the worm gear 4 to drive the worm wheel 3 to rotate, which helps to improve the ease of operation of the device.

[0034] Reference Figure 1 and Figure 2 The operator turns the rocker arm 42 to make the worm gear 4 rotate. The worm gear 4 drives the worm wheel 3 to rotate vertically. Under the support of the mounting plate 21, the worm wheel 3 drives the gearbox 1 to rotate vertically through the fixing plate 26, thereby adjusting the angle of the gearbox 1 to adapt to the working needs, which is conducive to improving the rotation and ease of use of the gearbox 1.

[0035] Reference Figure 1 and Figure 2The mounting plate 21 is equipped with a locking assembly for fixing the gearbox 1. The locking assembly includes an impeller 7 and a threaded clamping rod 8. The impeller 7 is sleeved on the outside of the fixing plate 26 and is coaxially fixedly connected to the fixing plate 26. The impeller 7 has an arc-shaped hole 71 in the circumferential direction, which is directly opposite to the threaded clamping rod 8. The threaded clamping rod 8 passes through the mounting plate 21 and the arc-shaped hole 71 in sequence and remains horizontal. The arc-shaped hole 71 supports the threaded clamping rod 8. The threaded clamping rod 8 has an abutment plate 83 between the impeller 7 and the gearbox 1. After the gearbox 1 is adjusted to the required angle, the threaded clamping rod 8 is rotated so that the abutment plate 83 abuts and fits against the impeller 7, thereby fixing the impeller 7 and further fixing the fixing plate 26, and finally fixing the gearbox 1. This helps to improve the stability and applicability of the gearbox 1.

[0036] Screw reference Figure 1 and Figure 2 The clamping plate includes a gripping rod 81 and a threaded rod 82. The gripping rod 81 is installed on the side of the mounting plate 21 away from the worm gear 3. The threaded rod 82 passes through the mounting plate 21 and the arc-shaped hole 71. The gripping rod 81 and the end of the threaded rod 82 away from the worm gear 3 are fixedly connected. The gripping rod 81 is easy for the operator to hold and rotate, thereby pushing the threaded rod 82 to move along the axis of the rotating shaft 52, which helps to improve the convenience of the device operation.

[0037] Reference Figure 1 and Figure 2 The upper ends of the worm gear 3, the first fixing plate 5 and the second fixing plate 6 are all flush with the upper surface of the gearbox 1. The upper surface of the reducer is provided with a support column, and a disc 11 for connecting with external agricultural machinery is installed on the support column. The worm gear 3, the first fixing plate 5 and the second fixing plate 6 all give way to the disc 11, and the disc 11 provides installation space.

[0038] The implementation principle of a hand-cranked self-rotating reducer according to an embodiment of this application is as follows: the operator turns the rocker arm 42 to drive the worm gear 4 to rotate, the worm gear 4 drives the worm wheel 3 to rotate vertically, the worm wheel 3 drives the fixed plate 5 and the fixed plate 6 to rotate vertically, thereby causing the fixed plate 6 to drive the reducer housing 1 to rotate vertically, so as to adjust the angle of the reducer housing 1 to meet the working requirements. The impeller 7 is fixed by rotating the threaded clamping rod 8, thereby fixing the fixed plate 6, and finally fixing the reducer housing. During the use of the reducer housing 1, there is no need to disassemble the installed equipment to adjust the position and angle of the reducer housing 1. The angle can be changed by turning the rocker arm 42, which is beneficial to improving the ease of operation and applicability of the device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
