Technical Field
[0001] This utility model relates to the field of speed reducer technology, and in particular to a single-stage dual-output shaft speed reducer with different rotation directions. Background Technology
[0002] A speed reducer is a mechanical transmission device mainly used to reduce input speed while increasing output torque. It is widely used in various mechanical equipment to meet the speed and torque requirements under different working conditions. The speed reducer achieves its function through a series of gears or other mechanical transmission elements, and can effectively convert high-speed, low-torque input into low-speed, high-torque output.
[0003] Chinese Patent Publication No. CN222262391U, published on December 27, 2024, discloses a geared motor, including a motor and a gearbox. The motor includes a motor body and a pre-deceleration assembly. The pre-deceleration assembly includes a housing, a first transmission rod, a first transmission gear, a second transmission gear, a second transmission rod, and a third transmission gear. The gearbox has an input shaft at its right end, and the motor has an output shaft at its left end. The housing covers the left end of the motor. One end of the first transmission rod is rotatably mounted on the left end face of the motor, and the other end of the first transmission rod is rotatably mounted on the left inner wall of the housing. The first transmission gear and the second transmission gear are respectively sleeved on the outer periphery of the first transmission rod, with the first transmission gear located to the right of the second transmission gear.
[0004] Existing speed reducers, such as those mentioned above, achieve speed reduction transmission of the drive motor through the cooperation between gears and transmission shafts. In practical implementation, existing speed reducers can often only achieve single-stage single-output and cannot adapt to the collaborative requirements of two workpieces rotating in opposite directions. Therefore, it is urgent to propose a corresponding single-stage dual-output shaft speed reducer with different rotation directions to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a single-stage dual-output shaft reducer with different rotation directions in order to solve the above-mentioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A single-stage dual-output-shaft reducer with different rotation directions includes a reducer housing. A drive shaft, an output shaft one, and an output shaft two are rotatably connected to the inner wall of the reducer housing. A drive shaft gear, an output shaft gear one, and an output shaft gear two are respectively fixedly connected to the outer walls of the drive shaft, the output shaft one, and the output shaft gear two. The drive shaft gear meshes with the output shaft gear one. A transmission component for driving the drive shaft gear and the output shaft gear two is integrated into the inner wall of the reducer housing.
[0008] Preferably, the transmission assembly includes a driven shaft rotatably connected to the inner wall of the reducer housing, a driven shaft gear fixedly connected to the outer wall of the driven shaft, and the driven shaft gear meshing with both the driving shaft gear and the output shaft gear.
[0009] Preferably, the number of teeth on the driving shaft gear and the driven shaft gear are the same, and the number of teeth on the first output shaft gear and the second output shaft gear are the same.
[0010] Preferably, the vertical ends of the first output shaft are rotatably connected to the reducer housing via bearings one and two, the vertical ends of the drive shaft are rotatably connected to the reducer housing via bearings three and four, the vertical ends of the driven shaft are rotatably connected to the reducer housing via bearings five and six, and the vertical ends of the second output shaft are rotatably connected to the reducer housing via bearings seven and eight.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0012] 1. In this application, the left side of the drive shaft gear cooperates with the first output shaft gear to form a gear transmission, the right side of the drive shaft gear cooperates with the driven shaft gear to form a gear transmission, and the right side of the driven shaft gear cooperates with the second output shaft gear to form a gear transmission. When the motor drives the drive shaft rod and the drive shaft gear to rotate clockwise, the drive shaft gear drives the first output shaft gear and the first output shaft to rotate counterclockwise. The driven shaft gear and the driven shaft rod also rotate counterclockwise. The driven gear, through meshing with the second output shaft gear, drives the second output shaft gear and the second output shaft to rotate clockwise. This achieves dual output in different rotation directions in a single stage. Moreover, the drive shaft gear and the driven shaft gear, which have the same number of teeth, have a difference in the number of teeth compared to the first output shaft gear and the second output shaft gear, which have the same number of teeth. Therefore, they can achieve the effect of speed reduction transmission at the output end of the motor.
[0013] 2. In this application, the driving shaft, driven shaft, output shaft one and output shaft two have corresponding bearings at both ends that rotate with the reducer housing, thereby ensuring the stable operation of the driving shaft, driven shaft, output shaft one and output shaft two, and thus improving the stability of the single-stage dual output shaft reducer with different rotation directions.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This utility model provides a technical solution:
[0021] A single-stage dual-output shaft reducer with different rotation directions includes a reducer housing 1. A drive shaft 2, an output shaft 6, and an output shaft 8 are rotatably connected to the inner wall of the reducer housing 1. A drive shaft gear 3, an output shaft gear 7, and an output shaft gear 9 are respectively fixedly connected to the outer walls of the drive shaft 2, the output shaft 6, and the output shaft 8. The drive shaft gear 3 and the output shaft gear 7 are meshed. A transmission component for driving the drive shaft gear 3 and the output shaft gear 9 is integrated into the inner wall of the reducer housing 1.
[0022] The left side of the drive shaft gear 3 engages with the output shaft gear 7 to form a gear transmission, while the right side of the drive shaft gear 3 engages with the driven shaft gear 5 to form a gear transmission. The right side of the driven shaft gear 5 engages with the output shaft gear 9 to form a gear transmission. When the motor drives the drive shaft rod 2 and the drive shaft gear 3 to rotate clockwise, the drive shaft gear 3 drives the output shaft gear 7 and the output shaft 6 to rotate counterclockwise. The driven shaft gear 5 and the driven shaft rod 4 also rotate counterclockwise. The driven shaft gear 5, through meshing with the output shaft gear 9, drives the output shaft gear 9 and the output shaft 8 to rotate clockwise. This achieves dual output in different rotation directions in a single stage. The drive shaft gear 3 and the driven shaft gear 5, which have the same number of teeth, have a difference in the number of teeth compared to the output shaft gear 7 and the output shaft gear 9, which can achieve the effect of speed reduction transmission at the motor output end.
[0023] Specifically, such as Figure 2 and Figure 3 As shown, the transmission assembly includes a driven shaft 4 rotatably connected to the inner wall of the reducer housing 1. A driven shaft gear 5 is fixedly connected to the outer wall of the driven shaft 4. The driven shaft gear 5 meshes with both the driving shaft gear 3 and the output shaft gear 9. This enables the driving shaft gear 3 and the output shaft gear 9 to mesh and transmit power while maintaining the same rotation direction. The driving shaft gear 3 and the driven shaft gear 5 have the same number of teeth, and the output shaft gear 7 and the output shaft gear 9 have the same number of teeth. The driving shaft gear 3 and the driven shaft gear 5, which have the same number of teeth, have a difference in the number of teeth compared to the output shaft gear 7 and the output shaft gear 9, thus achieving the effect of speed reduction transmission at the motor output end.
[0024] Specifically, such as Figure 2 and Figure 3 As shown, the vertical ends of output shaft 16 are rotatably engaged with the reducer housing 1 via bearings 10 and 11. The vertical ends of drive shaft 2 are rotatably engaged with the reducer housing 1 via bearings 12 and 13. The vertical ends of driven shaft 4 are rotatably engaged with the reducer housing 1 via bearings 14 and 15. The vertical ends of output shaft 28 are rotatably engaged with the reducer housing 1 via bearings 16 and 17. Each end of drive shaft 2, driven shaft 4, output shaft 16, and output shaft 28 has corresponding bearings that rotatably engage with the reducer housing 1, thus ensuring the stable operation of drive shaft 2, driven shaft 4, output shaft 16, and output shaft 28, thereby improving the stability of the single-stage dual-output shaft reducer with different rotation directions.
[0025] Working principle: The left side of the drive shaft gear 3 meshes with the output shaft gear 7 to form a gear transmission. The right side of the drive shaft gear 3 meshes with the driven shaft gear 5 to form a gear transmission. The right side of the driven shaft gear 5 meshes with the output shaft gear 9 to form a gear transmission. When the motor drives the drive shaft 2 and drive shaft gear 3 to rotate clockwise, the drive shaft gear 3 drives the output shaft gear 7 and output shaft 6 to rotate counterclockwise. The driven shaft gear 5 and driven shaft 4 also rotate counterclockwise. The driven shaft gear 5, through meshing with the output shaft gear 9, drives the output shaft gear 9 and output shaft 8 to rotate clockwise. This achieves dual output in different rotational directions in a single stage. The drive shaft gear 3 and driven shaft gear 5, which have the same number of teeth, have a difference in the number of teeth compared to the output shaft gear 7 and output shaft gear 9, which also have the same number of teeth. Therefore, they can achieve the effect of speed reduction transmission at the motor output end. Both ends of the drive shaft 2, driven shaft 4, output shaft 6, and output shaft 8 have corresponding bearings that rotate with the reducer housing 1, thereby ensuring the stable operation of the drive shaft 2, driven shaft 4, output shaft 6, and output shaft 8, and thus improving the stability of the single-stage dual output shaft reducer in different rotational directions.
[0026] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
