Description

Technical Field

[0001] The utility model relates to the technical field of reduction motors, in particular to a manual needle swing speed regulation reducer. Background Art

[0002] A reduction motor is a device that combines an electric motor with a reduction gear. It converts the high speed and low torque of the electric motor into low speed and high torque through the reduction gear to meet specific application requirements. A reduction motor is usually composed of an electric motor, a reduction gear and an output shaft. Traditional reduction gear housings are generally arranged in an integral structure, so it is inconvenient to replace the internal wear structure, and it is also inconvenient to inject oil into the interior for protection, which makes the reduction gear inconvenient to use.

[0003] Patent No. CN211039599U in the prior art discloses an easy-to-use speed-regulating reducer, which separates the traditional reducer housing into a whole consisting of a housing, a bottom plate and a top plate, and adjusts the pull ring to make the plug rod slide inside the socket, so that the top plate and the housing can be easily separated, thereby facilitating the replacement, maintenance and oiling of the wear structure inside the housing, extending the service life of the reducer, and being suitable for promotion. However, in actual use of the above-mentioned prior art, the reducer is generally speed-regulated by a control system, which is not convenient for manual speed regulation. When used in relatively simple working environments, the cost of use is high, so it needs further improvement. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a speed reducer for manual needle swing speed regulation.

[0007] According to the above technical solution, preferably, the fixing assembly includes two threaded rods and four threaded sleeves, the four threaded sleeves are movably mounted on the two threaded rods respectively, a plurality of slots are opened on the second rotating shaft, and one end of the two threaded rods passes through two of the slots respectively.

[0008] According to the above technical solution, preferably, a connecting piece is movably provided on the other side of the installation frame, and one end of the first rotating shaft extends out of the installation frame and is fixedly connected to the connecting piece. It can be seen that in the above technical solution, the connecting piece is connected to the external rotating shaft by bolts.

[0009] According to the above technical solution, preferably, the bottom edges of both sides of the installation frame are fixedly connected with side panels. It can be seen that in the above technical solution, the side panels are mounted on the base by bolts, thereby fixing the installation frame.

[0010] According to the above technical solution, preferably, the front side of the motor is movably connected with a sealing cover through a buckle. It can be seen that in the above technical solution, the sealing cover is opened and lubricating oil is added into the installation frame.

[0011] According to the above technical solution, preferably, a rotating assembly is provided on the second rotating shaft, and the rotating assembly includes a third rotating shaft, a first pulley, a second pulley and a stirring blade.

[0012] According to the above technical solution, preferably, one end of the third rotating shaft is movably connected to the mounting frame through a bearing, the first pulley is fixedly sleeved on the second rotating shaft, the second pulley is fixedly sleeved on the third rotating shaft, and one side of the stirring blade is fixedly connected to the third rotating shaft.

[0013] Technical effects and advantages of the utility model:

[0014] The utility model drives the second rotating shaft to rotate through the operation of the motor, thereby driving the swing needle to rotate. The swing needle can drive the first rotating shaft to rotate, turn off the motor and open the sealing cover, and then rotate the threaded sleeve and make it away from the threaded insertion rod, so as to release the fixation between the swing needle and the second rotating shaft, move the swing needle horizontally and make the two second gears mesh. Similarly, the swing needle and the second rotating shaft are fixed by two threaded insertion rods and four threaded sleeves, and the position of the third gear on the swing needle is adjusted in the same way, which is convenient for manual speed regulation and effectively reduces the use cost.

[0015] The utility model also opens the sealing cover and adds lubricating oil into the installation frame. When the second rotating shaft rotates, the second rotating shaft can drive the third rotating shaft to rotate, thereby driving the stirring blade to rotate. The stirring blade stirs the lubricating oil in the installation frame, so that the lubricating oil splashes onto the first gear, the second gear and the third gear, thereby lubricating the first gear, the second gear and the third gear. The utility model has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1:

[0026] like Figure 1-5 As shown, a manual pendulum speed regulation reducer includes a motor 1 and a mounting frame 2, and the motor 1 is fixedly mounted on one side of the mounting frame 2, the output shaft end of the motor 1 is fixedly connected to a second rotating shaft 15, and one end of the second rotating shaft 15 extends into the mounting frame 2 and is movably connected thereto through a bearing, a pendulum pin 8 is movably sleeved on the second rotating shaft 15, a fixing component is provided between the pendulum pin 8 and the second rotating shaft 15, a first rotating shaft 3 is movably connected to the position of the pendulum pin 8 inside the mounting frame 2 and located at the top of the pendulum pin 8 through a bearing, a first rotating shaft 3 and a pendulum pin 8 are fixedly sleeved with a first gear 9, a second gear 10 and a third gear 11, the fixing component includes two threaded inserts 12 and four threaded sleeves 13, the four threaded sleeves 13 are movably sleeved on the two threaded inserts 12, a plurality of slots 14 are provided on the second rotating shaft 15, and one end of the two threaded inserts 12 passes through two of the slots 14 respectively.

[0027] Furthermore, a connecting piece 4 is movably provided on the other side of the mounting frame 2, and one end of the first rotating shaft 3 extends out of the mounting frame 2 and is fixedly connected to the connecting piece 4, and side panels 6 are fixedly connected at the bottom edge positions on both sides of the mounting frame 2, and the connecting piece 4 is connected to the external rotating shaft by bolts, and the side panels 6 are installed on the base by bolts, thereby fixing the mounting frame 2.

[0028] When in use, start the motor 1, and the motor 1 drives the second rotating shaft 15 to rotate, thereby driving the pendulum needle 8 to rotate. Since the first gear 9 on the pendulum needle 8 is meshed with the third gear 11 on the first rotating shaft 3, the pendulum needle 8 can drive the first rotating shaft 3 to rotate. Turn off the motor 1 and open the sealing cover 5, and then rotate the threaded sleeve 13 and move it away from the threaded insertion rod 12, so as to release the fixation between the pendulum needle 8 and the second rotating shaft 15, move the pendulum needle 8 horizontally and make the two second gears 10 mesh. Similarly, the pendulum needle 8 and the second rotating shaft 15 are fixed by two threaded insertion rods 12 and four threaded sleeves 13. Similarly, the position of the third gear 11 on the pendulum needle 8 is adjusted to facilitate manual speed regulation and effectively reduce the cost of use.
