Description

Helical gear reducer transmission mechanism Technical Field

[0001] This utility model relates to the field of speed reducer technology, and more specifically, to a helical gear speed reducer transmission mechanism. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] Among them, patent CN217926969U discloses a two-stage worm gear helical gear reducer, which relates to the field of reducer technology. It includes a housing, comprising a lower housing and an upper housing. The top of the lower housing and the bottom of the upper housing are fixed. A drive shaft and an output shaft are rotatably connected to the two ends of the top of the lower housing, respectively. One end of the output shaft passes through the housing. A transmission assembly is installed between the drive shaft and the output shaft. A baffle is fixedly connected inside the housing, and a movable frame is slidably connected to the inner wall of the baffle.

[0004] When in use, this structure uses a movable frame to engage the worm gear and worm after mold closing. The position of the movable frame is then fixed by baffles and bolts, ensuring the engagement of the worm gear and worm. However, the movable frame alone does not provide adequate support for the gears and cannot achieve the function of providing enveloping support for the gear structure. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a helical gear reducer transmission mechanism, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a helical gear reducer transmission mechanism, including a base, on which a support component is provided;

[0007] The support assembly includes a first helical gear disposed within a base, a limiting sleeve disposed on the outer side of the base, a second helical gear rotatably connected to the middle of the limiting sleeve, both the limiting sleeve and the second helical gear extending to the bottom side of the first helical gear, a misalignment opening being provided at one end of the limiting sleeve, a central cylinder fixedly disposed in the middle of the first helical gear, a second drive shaft fixedly disposed in the middle of the central cylinder, a central ring rotatably connected to the bottom of the second drive shaft, and the central ring being fixedly disposed at the bottom of the inner wall of the base;

[0008] Optionally, in a possible implementation, a first drive shaft is fixedly provided at one end of the second helical gear, a retaining ring is rotatably connected to the outer side of the first drive shaft, the retaining ring is fixedly provided on the outer side of the limiting sleeve, a cover plate is bolted to the top of the base, the cover plate covers the outer side of the second drive shaft, the second drive shaft is rotatably connected to the cover plate, the bottom of the first helical gear extends to the outer side of the second helical gear and meshes with the second helical gear, and the vertical cross-sectional shape of one end of the limiting sleeve is set to a tapered shape;

[0009] The technical effects and advantages of this utility model are as follows:

[0010] By setting up support components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of each structure, when the second drive shaft is used as the output power source, the second drive shaft drives the central cylinder and the first helical gear to rotate. When the first helical gear rotates, it drives the second helical gear to rotate. When the first drive shaft is used as the power source, the first drive shaft drives the second helical gear to rotate, which in turn drives the first helical gear to rotate. It is easy to install the power source on the first drive shaft or the second drive shaft for output according to the requirements, so as to realize the function of power conversion of the conveying direction.

[0011] Furthermore, the vertical cross-section of one end of the limiting sleeve is set to a tapered shape to achieve the function of enveloping protection for the second helical gear. At the same time, the setting of the central ring facilitates the positioning of the central cylinder when the central cylinder and the second transmission shaft rotate. The setting of the misalignment port facilitates the avoidance of interference between the second helical gear and the first helical gear, ensuring transmission stability.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in Figures 1-4, the helical gear reducer transmission mechanism, through the support assembly set on the base 1, when the second transmission shaft 9 is used as the output power source, the second transmission shaft 9 drives the central cylinder 2 and the first helical gear 3 to rotate. When the first helical gear 3 rotates, it drives the second helical gear 5 to rotate. When the first transmission shaft 8 is used as the power source, the first transmission shaft 8 drives the second helical gear 5 to rotate, which in turn causes the second helical gear 5 to drive the first helical gear 3 to rotate. It is easy to install the power source on the first transmission shaft 8 or the second transmission shaft 9 for output according to the requirements. At the same time, the vertical cross-sectional shape of one end of the limiting sleeve 4 is set to a tapered shape to achieve the function of forming a wrap-around protection for the second helical gear 5. The specific structural settings of the components are as follows.

[0020] The support assembly includes a first helical gear 3 disposed inside the base 1, a limiting sleeve 4 disposed on the outer side of the base 1, a second helical gear 5 rotatably connected to the middle of the limiting sleeve 4, the limiting sleeve 4 and the second helical gear 5 both extending to the bottom side of the first helical gear 3, a misalignment opening 7 opened at one end of the limiting sleeve 4, a central cylinder 2 fixedly disposed in the middle of the first helical gear 3, a second drive shaft 9 fixedly disposed in the middle of the central cylinder 2, a central ring 6 rotatably connected to the bottom of the second drive shaft 9, and the central ring 6 fixedly disposed at the bottom of the inner wall of the base 1.

[0021] Specifically, as shown in Figures 2, 3, and 4, the second helical gear 5 meshes with the first helical gear 3, which facilitates the rotation of the central cylinder 2 and the first helical gear 3 when the second transmission shaft 9 is used as the output power source. When the first helical gear 3 rotates, it drives the second helical gear 5 to rotate, thereby realizing the function of power conversion of the conveying direction. At the same time, the central ring 6 facilitates the positioning of the central cylinder 2 when the second transmission shaft 9 rotates, and the misalignment opening 7 facilitates the avoidance of interference between the second helical gear 5 and the first helical gear 3.

[0022] One end of the second helical gear 5 is fixedly provided with a first transmission shaft 8. A retaining ring 11 is rotatably connected to the outside of the first transmission shaft 8. The retaining ring 11 is fixedly provided on the outside of the limiting sleeve 4. A cover plate 10 is installed on the top of the base 1 by bolts. The cover plate 10 covers the outside of the second transmission shaft 9. The second transmission shaft 9 is rotatably connected to the cover plate 10. The bottom of the first helical gear 3 extends to the outside of the second helical gear 5 and meshes with the second helical gear 5. The vertical cross-sectional shape of one end of the limiting sleeve 4 is set as conical.

[0023] Specifically, as shown in Figures 1, 2 and 3, the vertical cross-sectional shape of one end of the limiting sleeve 4 is set to a tapered shape to achieve the function of forming a wrap-around protection for the second helical gear 5. At the same time, the setting of the first transmission shaft 8 makes it convenient for the first transmission shaft 8 to drive the second helical gear 5 to rotate when the first transmission shaft 8 is used as a power source, thereby causing the second helical gear 5 to drive the first helical gear 3 to rotate.

[0024] The specific working principle is as follows: When the second drive shaft 9 is used as the output power source, the second drive shaft 9 drives the central cylinder 2 and the first helical gear 3 to rotate. When the first helical gear 3 rotates, it drives the second helical gear 5 to rotate. When the first drive shaft 8 is used as the power source, the first drive shaft 8 drives the second helical gear 5 to rotate, which in turn drives the first helical gear 3 to rotate. It is easy to install the power source on the first drive shaft 8 or the second drive shaft 9 for output according to the requirements. At the same time, the vertical cross-section shape of one end of the limiting sleeve 4 is set to a conical shape to achieve the function of forming a wrap-around protection for the second helical gear 5. At the same time, the setting of the central ring 6 makes it convenient to position the central cylinder 2 when the central cylinder 2 and the second drive shaft 9 rotate. The setting of the misalignment port 7 makes it convenient to avoid interference between the second helical gear 5 and the first helical gear 3.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
