Description

Adjustable speed reducer

[ technical field ] A method for producing a semiconductor device

The utility model relates to a speed reducer technical field especially relates to an adjustable speed reducer.

[ background of the invention ]

The speed reducer is generally used for low-speed and large-torque transmission equipment, and the purpose of reducing speed is achieved by meshing a motor, an internal combustion engine or other high-speed running power with a large gear on an output shaft through a gear with a small number of teeth on an input shaft of the speed reducer.

However, when the output torque needs to be adjusted, the torque cannot be quickly adjusted, so that it is necessary to provide an adjustable speed reducer capable of quickly adjusting the gear ratio.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming above-mentioned prior art's shortcoming, provide an adjustable speed reducer.

The utility model discloses can realize through following technical scheme:

the utility model discloses an adjustable speed reducer, which comprises an outer shell, be provided with on the shell and rotate the driving shaft of being connected with the shell, be fixed with driving gear I and driving gear II on the driving shaft, still be provided with the slide with shell sliding connection on the shell, be provided with on the slide and rotate the driven shaft of being connected with the slide, be fixed with driven gear I and driven gear II on the driven shaft. Drive the driving shaft through the motor and rotate, when the driving shaft rotates, driving gear I meshes with I meshing of driven gear on the driven shaft on driving shaft I, when the driving shaft rotates, the driven shaft rotates along with the driving shaft, when the slew velocity of driven shaft needs to be adjusted, promote the slide, the driven shaft moves along with the slide, I separation of driving gear on driven shaft I and the driving shaft, driven gear II moves II corresponding position of driving gear and meshes with driving gear II on the driven shaft, when the motor drives the driving shaft and rotates, the driven shaft rotates along with the driving shaft once more, because the drive ratio between driving gear I and driven gear I is inconsistent with driving gear II and driven gear II, only need the position of adjustment slide can realize adjusting the drive ratio between driving shaft and the driven shaft, thereby adjust the output speed of driven shaft.

Preferably, a linkage shaft is arranged on the shell and corresponds to the driven shaft, the linkage shaft is rotatably connected with the shell, and the tail end of the linkage shaft is inserted into the driven shaft and is in sliding connection with the driven shaft. The driven shaft is supported through the linkage shaft, and stable rotation of the driven shaft is guaranteed.

Preferably, a handle is further fixed on the sliding plate. The skateboard can be more conveniently pushed through the handle.

Preferably, a plurality of sliding rails are fixed on the housing, and the sliding plate is connected with the sliding rails in a sliding manner.

Preferably, the sliding plate is further fixed with a fixing plate, and the fixing plate is fixed on the shell through a bolt.

Compared with the prior art, the utility model has the advantages that:

the transmission ratio between the driving shaft and the driven shaft can be adjusted only by adjusting the position of the sliding plate, so that the output rotating speed of the driven shaft is adjusted.

[ detailed description ] A

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings:

as shown in fig. 1 to 3, the utility model discloses an adjustable speed reducer, including shell 1, be provided with on shell 1 and rotate the driving shaft 7 of being connected with shell 1, be fixed with driving gear I8 and driving gear II 9 on the driving shaft 7, still be provided with on shell 1 with shell 1 sliding connection's slide 2, be provided with on slide 2 and rotate the driven shaft 10 of being connected with slide 2, be fixed with driven gear I11 and driven gear II 12 on the driven shaft 10. The driving shaft 7 is driven to rotate by a motor, when the driving shaft 7 rotates, a driving gear I8 on the driving shaft 7 is meshed with a driven gear I11 on a driven shaft 10, when the driving shaft 7 rotates, the driven shaft 10 rotates along with the driving shaft 7, when the rotating speed of the driven shaft 10 needs to be adjusted, a sliding plate 2 is pushed, the driven shaft 10 moves along with the sliding plate 2, the driven gear I11 on the driven shaft 10 is separated from the driving gear I8 on the driving shaft 7, a driven gear II 12 on the driven shaft 10 moves to a position corresponding to the driving gear II 9 and is meshed with the driving gear II 9, when the driving shaft 7 is driven to rotate by the motor, the driven shaft 10 rotates along with the driving shaft 7 again, and as the transmission ratio between the driving gear I8 and the driven gear I11 is inconsistent with the driving gear II 9 and the driven gear II 12, the transmission ratio between the driving shaft 7 and the driven shaft 10 can be adjusted only by adjusting the position of the sliding plate 2, thereby adjusting the output rotational speed of the driven shaft 10.

The linkage shaft 13 is arranged on the position, corresponding to the driven shaft 10, of the shell 1, the linkage shaft 13 is rotatably connected with the shell 1, and the tail end of the linkage shaft 13 is inserted into the driven shaft 10 and is in sliding connection with the driven shaft 10. The driven shaft 10 is supported through the linkage shaft 13, so that the stable rotation of the driven shaft 10 is ensured.

Wherein, the sliding plate 2 is also fixed with a handle 3. The sliding plate 2 is more conveniently pushed by the handle 3.

Wherein, be fixed with many slide rails 4 on the shell 1, slide 2 and slide rail 4 sliding connection.
