Description

Technical Field

[0001] The utility model relates to the technical field of speed reduction motors, in particular to a super-rotating speed reduction motor. Background Art

[0002] A speed reduction motor refers to an integrated body of a speed reducer and a motor (motor). Such an integrated body is usually also called a gear motor or a gear motor. Usually, it is integrally assembled by a professional speed reducer manufacturer and then supplied as a complete set together with the motor.

[0003] For example, the speed reduction motor disclosed in the publication number CN202094751U includes a main motor, a worm extending from the main motor, a first gear meshing with the worm, a second gear meshing with the first gear, a third gear meshing with the second gear, a fourth gear meshing with the third gear, and an output shaft fixed to the fourth gear; the speed reduction motor further includes an open box body disposed on one side of the main motor and used for covering the first gear, the second gear, the third gear, and the fourth gear.

[0004] However, in the prior art, when the speed ratio of the speed reduction motor is set to be fixed and non-adjustable, its limitation lies in restricting the adaptability and flexibility of the equipment under various working conditions. In order to meet the requirements of different application scenarios, it is often necessary to separately equip a dedicated speed reduction motor for each specific working condition or application scenario. Although this approach can ensure the optimal performance of the equipment in its specific field, it inevitably brings high procurement, maintenance, and replacement costs, which not only increases the economic burden of the enterprise but also has an adverse impact on production efficiency and flexibility. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem of the inability to freely adjust the speed ratio in the prior art, and a super-rotating speed reduction motor is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a super-rotating speed reduction motor, including a motor main body and a housing, an output shaft is rotatably connected to one side of the housing, a transmission mechanism is installed inside the housing, and a positioning member is installed on the top of the housing;

[0007] The transmission mechanism includes an input shaft and a first transmission gear. A movable sleeve is slidably connected to the surface of the input shaft. One end of the movable sleeve is fixedly connected to a first driving gear on its outer surface, and the other end of the movable sleeve is fixedly connected to a second driving gear on its outer surface. A limiting sleeve is fixedly connected to the middle of the movable sleeve. A pushing plate is clamped in the middle of the inner cavity of the limiting sleeve. A second transmission gear is fixedly connected to the inside of the first transmission gear. The first transmission gear is meshed with the first driving gear, and the second transmission gear is meshed with the second driving gear. A convex block is fixedly connected to the outer surface of the input shaft, and a clamping groove is formed inside the movable sleeve. The clamping groove is clamped with the convex block.

[0008] Preferably, the input shaft is fixedly connected to the output end of the motor body, and the output shaft is fixedly connected to the first transmission gear.

[0009] Preferably, a limiting frame is fixedly connected to the inside of the housing, and a sliding rod is fixedly connected to the inside of the limiting frame.

[0010] Preferably, the top end of the pushing plate is slidably connected to the sliding rod, and the top end of the pushing rod is slidably connected to the inside of the limiting frame.

[0011] Preferably, support frames are rotatably connected to the outer surfaces of both ends of the input shaft, and the support frames are fixedly connected to the inner wall of the housing.

[0012] Preferably, the positioning member includes a fixed block, and a plugging rod is slidably connected to the inside of the fixed block.

[0013] Preferably, a control frame is fixedly connected to the top of the pushing plate, and three plugging slots are formed on one side of the control frame.

[0014] Preferably, a limiting plate is fixedly connected to the outer surface of the plugging rod, and a spring is sleeved on the surface of the plugging rod. The plugging rod is plugged into the plugging slot.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0016] 1. In the present utility model, by driving the control frame to move, it is converted into a linear motion of the pushing plate. The sliding rod guides to ensure the stable sliding of the pushing plate. The pushing plate pushes the limiting sleeve to move, controlling the gear meshing. When the first driving gear is meshed with the first transmission gear, the second pair of gears is separated, and vice versa. This design can flexibly adjust the rotation direction and speed ratio of the output shaft to adapt to complex working conditions. The precise guiding of the sliding rod and the stable support of the limiting frame ensure the stability and precision of the pushing plate and the limiting sleeve during long-term and high-frequency motion. The overall mechanism is efficient and reliable, meeting diverse power transmission requirements.

[0017] 2. In the utility model, by pulling the plug rod in advance and compressing the spring to store energy, when the control frame moves, the spring releases energy and pushes the limit plate and the plug rod toward the side wall of the control frame. When the plug slot is aligned with the plug rod, the spring pushes the plug rod firmly into the slot and locks the control frame. This locking ensures stable transmission and controls the push of the push plate on the limit sleeve. When the first or second active gear is transmitting, the control frame remains stationary to prevent transmission interruption or failure caused by random movement. The entire mechanism is exquisitely designed to ensure continuous and stable operation of the transmission system. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1: Figure 1 - Figure 3As shown in the figure, the present utility model provides a super-rotary reduction motor, which includes a motor main body 1 and a housing 2. One side of the housing 2 is rotatably connected to an output shaft 4. A transmission mechanism 3 is installed inside the housing 2, and a positioning member 5 is installed on the top of the housing 2;

[0026] The transmission mechanism 3 includes an input shaft 34 and a first transmission gear 35. A movable sleeve 33 is slidably connected to the surface of the input shaft 34. One end of the outer surface of the movable sleeve 33 is fixedly connected to a first driving gear 331, and the other end of the outer surface of the movable sleeve 33 is fixedly connected to a second driving gear 332. A limiting sleeve 37 is fixedly connected to the middle of the movable sleeve 33. A push plate 38 is clamped in the middle of the inner cavity of the limiting sleeve 37. A second transmission gear 36 is fixedly connected to the inside of the first transmission gear 35. The first transmission gear 35 is meshed with the first driving gear 331, and the second transmission gear 36 is meshed with the second driving gear 332. A convex block 341 is fixedly connected to the outer surface of the input shaft 34, and a clamping groove 333 is formed inside the movable sleeve 33. The clamping groove 333 is clamped with the convex block 341. The input shaft 34 is fixedly connected to the output end of the motor main body 1, and the output shaft 4 is fixedly connected to the first transmission gear 35. A limiting frame 31 is fixedly connected to the inside of the housing 2, and a sliding rod 32 is fixedly connected to the inside of the limiting frame 31. The top end of the push plate 38 is slidably connected to the sliding rod 32, and the top end of the push rod is slidably connected to the inside of the limiting frame 31. The outer surfaces of both ends of the input shaft 34 are rotatably connected to a support frame 342, and the support frame 342 is fixedly connected to the inner wall of the housing 2.

[0027] Next, the specific settings and functions of this embodiment will be described in detail. When the operator drives the control frame 39 to move along a preset trajectory, it is converted into a linear motion of the push plate 38. Through the precise guidance of the sliding rod 32, it is ensured that the push plate 38 slides smoothly and without deviation inside the limiting frame 31.

[0028] The interaction between the push plate 38 and the limiting sleeve 37. As the push plate 38 advances, a force is applied to the limiting sleeve 37 to drive it to move along a predetermined path. The movement of the limiting sleeve 37.

[0029] When the first driving gear 331 is closely meshed with the first transmission gear 35, power is efficiently transmitted through this pair of gears, while the second driving gear 332 is separated from the second transmission gear 36, avoiding unnecessary energy loss and mechanical interference. Vice versa, when the second driving gear 332 is meshed with the second transmission gear 36, the first driving gear 331 is automatically disengaged from the first transmission gear 35, realizing a rapid switching of the transmission path.

[0030] It can flexibly adjust the rotation direction and speed ratio of the output shaft 4, so as to meet the power transmission requirements under various complex working conditions. In addition, the precise guidance of the sliding rod 32 and the stable support of the limit frame 31 ensure that the pushing plate 38 and the limit sleeve 37 can still maintain accurate positions and stable performance during long-term and high-frequency movements.

[0031] Embodiment 2: As Figure 1 and Figure 4 shown, the positioning member 5 includes a fixed block 51, and a plugging rod 52 is slidably connected to the inner side of the fixed block 51. A control frame 39 is fixedly connected to the top of the pushing plate 38, and three plugging slots 391 are formed on one side of the control frame 39. A limit plate 54 is fixedly connected to the outer surface of the plugging rod 52, and a spring 53 is sleeved on the surface of the plugging rod 52. The plugging rod 52 is plugged into the plugging slot 391.

[0032] The overall effect achieved by this entire embodiment is that, first, by pre-pulling the plugging rod 52, the limit plate 54 smoothly slides inside the fixed block 51, and at the same time, the spring 53 is compressed, storing the necessary elastic potential energy for the subsequent locking action. As the control frame 39 then moves, the originally compressed spring 53 releases the stored energy, pushing the limit plate 54 and the plugging rod 52 to quickly approach the side wall of the control frame 39.

[0033] As the control frame 39 continues to move, the plugging slot 391 and the plugging rod 52 reach an aligned state. Under the continuous push of the spring 53, the plugging rod 52 steadily slides into the plugging slot 391. When the plugging rod 52 is completely inserted into the plugging slot 391, the control frame 39 is in a stable locked state. This locking not only ensures the stability of the control frame 39 during the transmission process but also, through its indirect action, controls the pushing force and direction of the pushing plate 38 on the limit sleeve 37. Therefore, when the first driving gear 331 or the second driving gear 332 is in transmission, the control frame 39 can remain stationary, effectively avoiding transmission interruption or failure that may be caused by random movement.

[0034] The usage method and working principle of this device: Before the control frame 39 moves, pull the plugging rod 52 so that the limit plate 54 on the outer surface of the plugging rod 52 slides inside the fixed block 51. During this process, the spring 53 on the surface of the plugging rod 52 is squeezed and compressed. Subsequently, when the control frame 39 starts to move, release the plugging rod 52. Under the action of the restoring force, the spring 53 pushes the limit plate 54, thereby driving the plugging rod 52 to move together. The plugging rod 52 then abuts against the side wall of the control frame 39 and, as the control frame 39 continues to move, until the plugging slot 391 on the side wall is aligned with the plugging rod 52. At this time, under the continuous push of the spring 53, the limit plate 54 and the plugging rod 52 smoothly enter the plugging slot 391, achieving the locked state of the control frame 39.

[0035] In the locked state, the control frame 39 not only firmly fixes its own position but also indirectly controls the pushing action of the pushing plate 38 on the limiting sleeve 37. This locking mechanism ensures that when the first driving gear 331 or the second driving gear 332 is in transmission, the control frame 39 will not affect the stability and continuity of the transmission process due to random movement.

[0036] As the control frame 39 moves, the pushing plate 38 slides linearly inside the limiting frame 31 under the restriction of the sliding rod 32. During this sliding process, the pushing plate 38 exerts a force on the limiting sleeve 37 to push the limiting sleeve 37 to move. By moving the limiting sleeve 37, the positions of the first driving gear 331 and the second driving gear 332 can be controlled, thereby achieving the meshing or separation of the first driving gear 331 and the second driving gear 332 from their corresponding transmission gears (the first transmission gear 35 or the second transmission gear 36).

[0037] Specifically, when the first driving gear 331 is in meshing with the first transmission gear 35, the first driving gear 331 drives the first transmission gear 35 to rotate, while at this time, the second driving gear 332 and the second transmission gear 36 are in a non-meshing state. Conversely, as the sliding sleeve moves, when the second driving gear 332 is in meshing with the second transmission gear 36, the first driving gear 331 and the first transmission gear 35 are in a non-meshing state.

[0038] Through the switching operation of the sliding sleeve, the rotation direction and speed ratio of the output shaft 4 can be flexibly changed to adapt to different working requirements and working conditions. This design not only improves the flexibility and adaptability of the transmission system but also enhances its reliability and stability in practical applications.

[0039] The above is only the preferred embodiment of the present invention and is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
