Description

Technical Field

[0001] The invention belongs to the technical field of motor gear boxes, and in particular relates to a novel motor gear box. Background Art

[0002] The motor gearbox is an important component of modern mechanical transmission systems and is widely used in various automation equipment and industrial machinery. It is mainly composed of a motor, a gear set and a gearbox body, and is used to convert the motor's rotational power into the linear or rotational motion of the mechanical equipment.

[0003] In traditional motor gearboxes, the connection between the gear set and the output shaft is generally achieved through bearings. The bearings are installed inside the gearbox body to support the output shaft and maintain its stable rotation. However, in the long-term operation of existing motor gearboxes, the direct contact between the bearings and the output shaft is prone to wear, which affects the service life and performance of the gearbox. Due to the large contact area and friction between the bearing and the sleeve, it is easy for the bearing to deviate or get stuck during high-speed rotation, which in turn affects the stability of the output shaft and the operating efficiency of the gearbox. During operation, the friction between the bearing and the gear set will generate noise, making the operating environment of the motor gearbox not quiet enough.

[0004] In view of this, we propose a new type of motor gearbox, which effectively solves the problems of wear, deviation, jamming and noise in the prior art through a unique bearing design and structure, such as setting a ball bearing in the sleeve and the automatic idling of the bearing when a certain force is reached, and improves the performance and service life of the motor gearbox. Summary of the invention

[0005] The present invention aims to solve the technical problem that in the above-mentioned prior art, direct contact between the bearing and the output shaft of the motor gearbox during long-term operation easily leads to wear, thereby affecting the service life and performance of the gearbox.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A novel motor gearbox comprises a front cover and a rear cover, an output shaft, a gear set and a motor;

[0008] The front cover and the rear cover are respectively provided with shaft sleeves protruding outwards, and a plurality of ball bearings are arranged in the hole circles of the shaft sleeves for rotation around the circumferential direction;

[0009] The output shaft is used to connect with the gear set, and the two ends of the output shaft are respectively passed through the sleeves on the front cover and the rear cover. The output shaft is provided with a front bearing and a rear bearing located on both sides of the gear set. The front bearing and the rear bearing are respectively rotatably connected with the ball bearings in the sleeves on the front cover and the rear cover to prevent the front bearing or the rear bearing from deviating or getting stuck.

[0010] The output shaft is driven to rotate by the gear set driven by the motor installed on the front cover. When the force or speed of the output shaft exceeds the designed range during rotation, it will automatically idle to protect the gear set.

[0011] Preferably, the gear set is installed in a cavity enclosed by the front cover and the rear cover.

[0012] Preferably, the gear set includes an input gear, a double-layer gear A, a double-layer gear B and an output gear;

[0013] The output gear is fixed on the output shaft; the input gear is fixedly connected to the output end of the motor, and the input gear is also meshed with the large gear on the double-layer gear A, the small gear on the double-layer gear A is meshed with the large gear on the double-layer gear B, and the small gear on the double-layer gear B is meshed with the output gear.

[0014] Preferably, both ends of the wheel shafts on the double-layer gear A and the double-layer gear B are rotatably connected to the front cover and the rear cover respectively.

[0015] Preferably, the motor is fixed to the outer side of the front cover by screws A. By directly fixing the motor to the outer side of the front cover by screws A, the installation process is simplified, and the installation time and labor cost are reduced.

[0016] Preferably, the four corners of the front cover and the rear cover are fixed together by screws B. The fixing of screws B enhances the connection strength between the front cover and the rear cover.

[0017] Preferably, two mounting seats A with holes formed integrally therewith are symmetrically arranged on both sides of the upper end of the rear cover, and a mounting seat B with holes formed integrally therewith is arranged at the center of the lower end of the rear cover. The mounting seats A with holes and the mounting seats B with holes are formed integrally with the rear cover, which increases the structural strength of the rear cover and facilitates the integration of the gearbox into a larger system.

[0018] Compared with the prior art, the technical effects and advantages of the present invention are:

[0019] The gear set in the new motor gearbox is installed in the chamber surrounded by the front cover and the rear cover. Through multi-stage gear transmission, efficient power transmission and speed and torque adjustment are achieved. The front bearing and rear bearing on the output shaft are rotatably connected with the ball bearings in the sleeves on the front cover and the rear cover respectively. This design not only reduces wear, but also can automatically idle when the bearing is subjected to excessive force, protecting the gear set from damage.

[0020] The coordinated rotation of the bearings and ball bearings in this new motor gearbox reduces wear, reduces noise, and improves the operating accuracy and working environment of the gearbox. The design of the double-layer gears helps to disperse the vibration during the transmission process, reduce noise, and improve the working environment of the gearbox. The rotating connection of the axle increases the stability of the gear set, prevents the displacement of the gears during high-speed rotation, and ensures normal meshing. When the output shaft rotates with a force or speed outside the design range, it automatically idles to protect the gear set. The automatic idling function not only protects the gear set, but also reduces noise and achieves a better quiet effect. The improvement of the overall structure enables the new motor gearbox to maintain good performance in long-term use, improving the efficiency of equipment use and production reliability.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The following combination Figure 1-6 To further explain this application in detail,

[0030] The embodiment of the present application discloses a novel motor gearbox, including a front cover 1 and a rear cover 2, an output shaft 6, a gear set 7 and a motor 10; the motor 10 is fixed to the outer side of the front cover 1 by means of screws A11. The motor 10 is directly fixed to the outer side of the front cover 1 by means of screws A11, which simplifies the installation process and reduces the installation time and labor cost. The screw A11 fixation provides a stable connection, ensures the stability of the motor 10 during operation, and reduces the risk of loosening due to vibration. The screw A11 fixation method facilitates the maintenance and replacement of the motor 10, and the corresponding operation can be performed by simply removing the screws A11.

[0031] The four corners of the front cover 1 and the rear cover 2 are fixed together by screws B12. The screw B12 fixation enhances the connection strength between the front cover 1 and the rear cover 2, ensuring the structural stability of the entire gearbox during operation. The screw B12 fixation at the four corners helps to improve the sealing between the front cover 1 and the rear cover 2, preventing lubricating oil leakage and external contaminants from entering.

[0032] Two integrally formed mounting seats A13 with holes are symmetrically arranged on both sides of the upper end of the rear cover 2, and an integrally formed mounting seat B14 with holes is arranged at the center of the lower end of the rear cover 2. The mounting seats A13 with holes and the mounting seats B14 with holes are integrally formed with the rear cover 2, which increases the structural strength of the rear cover 2, makes the entire gearbox more stable after installation, and reduces structural problems caused by improper installation. The design of the mounting seats A13 with holes and the mounting seats B14 with holes facilitates the integration of the gearbox into a larger system, such as connecting to a conveyor belt, a robot or other automated equipment.

[0033] The front cover 1 and the rear cover 2 are respectively provided with shaft sleeves 3 protruding outwards, and a plurality of ball bearings 5 ​​are arranged in the hole ring 4 of the shaft sleeve 3 to rotate in the circumferential direction;

[0034] The output shaft 6 is used to connect with the gear set 7 and the two ends of the output shaft 6 are respectively passed through the sleeves 3 on the front cover 1 and the rear cover 2, and the gear set 7 is installed in the chamber surrounded by the front cover 1 and the rear cover 2. The chamber design allows the gear set 7 to be installed in a limited space, reducing the overall size, making the motor 10 gear box more compact, and easy to install and integrate into other equipment. The chamber can effectively prevent dust, moisture and other contaminants from entering the gear set 7, thereby protecting the gears from damage and extending their service life. The chamber design helps to retain lubricating oil, reduce oil loss, and ensure that the gear set 7 is fully lubricated during the entire operation process.

[0035] The gear set 7 includes an input gear 71, a double-layer gear A 72, a double-layer gear B 73 and an output gear 74;

[0036] The output gear 74 is fixed on the output shaft 6; the input gear 71 is fixedly connected to the output end of the motor 10, and the input gear 71 is also meshed with the large gear on the double-layer gear A72, the small gear on the double-layer gear A72 is meshed with the large gear on the double-layer gear B73, and the small gear on the double-layer gear B73 is meshed with the output gear 74. Through multi-stage gear transmission, power can be transmitted more effectively and the transmission efficiency can be improved. Multi-stage gear transmission can achieve speed and torque adjustment to meet the needs under different working conditions. Through the combination of different gears, more accurate speed and torque control can be achieved to improve the working accuracy of the system.

[0037] The two ends of the axles on the double-layer gears A72 and B73 are rotatably connected to the front cover 1 and the rear cover 2, respectively. This helps to disperse the vibration during the transmission process, reduce noise, and improve the working environment of the gearbox. The rotational connection of the axles can increase the stability of the gear set 7, prevent the gears from being displaced during high-speed rotation, and ensure the normal meshing of the gears.

[0038] The output shaft 6 is provided with a front bearing 8 and a rear bearing 9 located on both sides of the gear set 7. The front bearing 8 and the rear bearing 9 are rotatably connected to the ball bearing 5 in the shaft sleeve 3 on the front cover 1 and the rear cover 2, respectively, to prevent the front bearing 8 or the rear bearing 9 from deviating or getting stuck;

[0039] The motor 10 installed on the front cover 1 drives the gear set 7 to drive the output shaft 6 to rotate. When the force or speed of the output shaft 6 exceeds the design range during rotation, it will automatically idle to protect the gear set 7.

[0040] The novel motor gearbox mainly relies on its unique bearing design and structure. The motor 10 drives the gear set 7 through the installation position on the front cover 1. The gear set 7 is connected to the output shaft 6. When the motor 10 drives the gear set 7 to rotate, the output shaft 6 also rotates. A ball bearing 5 is arranged inside the sleeve 3. The front bearing 8 and the rear bearing 9 on the output shaft 6 are respectively rotatably connected with the ball bearing 5 in the sleeve 3 on the front cover 1 and the rear cover 2. During the rotation process, the bearing cooperates with the ball bearing 5 to make the output shaft 6 rotate smoothly. At the same time, the presence of the ball bearing 5 can prevent the bearing from directly contacting the sleeve 3 and reduce wear.

[0041] When the bearing reaches a certain force, it will automatically idle, which can prevent the gear from being damaged due to excessive torque, thereby increasing the service life of the gear. Idling can reduce the noise of the gear set 7 during rotation, achieving a better quiet effect. The coordinated rotation of the ball bearing 5 and the bearing helps to maintain the position of the output shaft 6 stable, prevent the bearing from deviating during high-speed rotation, and improve the running accuracy. The presence of the ball bearing 5 reduces the contact area between the bearing and the sleeve 3, reduces the friction, and thus avoids the phenomenon of the bearing being stuck due to excessive friction.

[0042] The design of the bearing and ball bearing 5 reduces the wear of the gear during rotation and prolongs the service life of the gear. The idling and ball bearing 5 design reduces noise, making the motor 10 gearbox quieter during operation. The optimization and improvement of the overall structure enables the new motor 10 gearbox to maintain good performance during long-term use and improves usability.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
