Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The purpose of the utility model is to provide a speed reducer to solve the problems existing in the above-mentioned prior art and to enable the input end bearing to be fully lubricated.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 6 As shown, this embodiment provides a reducer, including: a housing, a power input shaft 1, a power output shaft 2 and a transmission structure, the transmission structure is located in the housing, the input end of the power input shaft 1 extends out of the housing, the output end of the power input shaft 1 is connected to the transmission structure, the output end of the power output shaft 2 extends out of the housing, the input end of the power output shaft 2 is connected to the transmission structure, the power input shaft 1 and the housing are rotatably connected through an input end bearing 10, and the housing is provided with a lubrication channel structure, and the lubricating oil can lubricate the input end bearing 10 through the lubrication channel structure.

[0029] Specifically, in this embodiment, the outer shell includes a box cover 7, a box body 8 and a base 9. The box body 8 is detachably connected to the box cover 7 and the base 9 respectively. A foot 20 is provided at the bottom of the box body 8. The power output shaft 2 is rotatably connected to the box cover 7 through the output end bearing 11. The power input shaft 1 is rotatably connected to the base 9 through the input end bearing 10. The power input shaft 1 and the power output shaft 2 are arranged vertically.

[0030] In this embodiment, the transmission structure includes a first gear 3, a second gear 4, a third gear 5 and a fourth gear 6. The first gear 3 is arranged on the power input shaft 1, and the first gear 3 is engaged with the second gear 4. The first gear 3 and the second gear 4 are both bevel gears. The second gear 4 and the third gear 5 are both arranged on the support shaft 12 and are coaxially arranged. The support shaft 12 is rotatably connected to the box cover 7 through a transmission bearing 13. The fourth gear 6 is arranged on the power output shaft 2, and the third gear 5 is engaged with the fourth gear 6.

[0031] In this embodiment, an oil-slinging pan 14 is further provided on the power input shaft 1. The oil-slinging pan 14 and the first gear 3 are coaxially arranged. The oil-slinging pan 14 is located in the housing 8. The outer edge of the oil-slinging pan 14 is provided with a notch along the circumference of the oil-slinging pan 14. The edge of the oil-slinging pan 14 can enter below the liquid level of the lubricating oil in the housing 8. The oil-slinging pan 14 is used to throw the lubricating oil in the housing 8 into the lubrication channel structure.

[0032] In this embodiment, the inner wall of the box cover 7 is provided with a guide structure 15, which is provided at the junction of the box cover 7 and the box body 8. The lubrication channel structure includes a first oil circuit 16 opened on the box body 8 and an oil groove 19 and a second oil circuit 17 opened on the body seat 9. The first oil circuit 16, the oil groove 19 and the second oil circuit 17 are connected in sequence. One end of the second oil circuit 17 extends to the input end bearing 10. The height of the first oil circuit 16 is higher than that of the second oil circuit 17. The guide structure 15 is used to provide guidance for the lubricating oil so that the lubricating oil can enter the lubrication channel structure. Under the action of the oil-slinging plate 14, the lubricating oil in the box body 8 can enter the lubrication channel structure through the guide structure 15 to achieve lubrication of the input end bearing 10; the inner wall of the box cover 7 is also provided with a guide plate 18, which is used to guide the lubricating oil to the output end bearing 11 between the power output shaft 2 and the box cover 7 and the transmission bearing 13 between the transmission structure and the box cover 7. There are preferably two guide plates 18. Under the action of the oil-slinging plate 14, the lubricating oil is directed to the transmission bearing 13 through the action of one of the guide plates 18, and the lubricating oil can also be directed to the output end bearing 11 through the action of the other guide plate 18, thereby achieving lubrication of the transmission bearing 13 and the output end bearing 11.

[0033] The reducer of this embodiment utilizes a guide structure 15 to increase the area for collecting lubricating oil, controlling the direction of the lubricating oil and ensuring sufficient lubricating oil to lubricate the input-end bearing 10. By directing the lubricating oil to the lubrication channel structure, lubrication of the input-end bearing 10 is achieved, thereby resolving the issue of poor lubrication of the input-end bearing 10. Furthermore, the provision of the lubrication channel structure reduces the amount of lubricating oil used, requiring only that the edge of the oil-slinging pan 14 be positioned below the lubricating oil level. This avoids the problem of excessive operating resistance of the transmission structure caused by the use of large amounts of lubricating oil.

[0034] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
