Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of metallurgical rolling equipment, and particularly relates to a vertical speed reducer with an oil retaining lubricating ring structure. Background Art
[0002] In the metallurgical industry, the stable operation of speed reducers on the rolling equipment line and the aluminum smelting equipment line depends on bearings, lubrication, sealing, etc.
[0003] The inventor found the following defects during the operation of specific embodiments:
[0004] At present, the sealing structures of speed reducers are mainly divided into mechanical seals and oil seal seals. The traditional mechanical seal mainly uses an oil slinger ring and a gland to cooperate with the mechanical seal. However, due to space limitations in many current speed reducers, this cannot be achieved, which easily leads to poor sealing effect due to small space during on-site use, resulting in oil leakage from the speed reducer and ultimately causing the speed reducer to be unable to be used normally, bringing huge losses to actual production.
[0005] The lubrication of the speed reducer bearings is also equally important. The bearing lubrication is mainly divided into spraying through an oil pipe and spraying by gear splash. Due to many conditional limitations, the gear splash lubrication cannot be achieved; insufficient bearing lubrication causes the bearings of the speed reducer to be damaged, resulting in the speed reducer being unable to work normally, bringing huge losses to actual production.
[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and extremely complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model
[0007] 1. Technical problems to be solved by the utility model:
[0008] The utility model provides a vertical speed reducer with an oil retaining lubricating ring structure to solve the technical problems existing in the above background art.
[0009] 2. Technical solutions:
[0010] To achieve the above object, the technical solution provided by the utility model is: a vertical speed reducer with an oil retaining lubricating ring structure, the speed reducer includes a box body, a first output shaft is installed inside the box body, a shaft sleeve is fixedly installed outside the first output shaft, a bearing is installed inside the box body, the first output shaft is rotationally connected to the inside of the box body through the bearing, an oil retaining lubricating ring is welded on the inner side wall of the box body, an oil inlet hole is opened on the oil retaining lubricating ring, an oil seal part is installed inside the oil inlet hole, and the oil inlet hole can be externally connected to an oil pipe.
[0011] Furthermore, the oil seal includes an inner oil seal ring and an outer oil seal ring. The inner oil seal ring is installed on the shaft sleeve, and the outer oil seal ring is installed inside the oil inlet hole.
[0012] Furthermore, an input shaft is installed at one end inside the box body. A first bevel gear is installed at the end of the input shaft. An intermediate shaft is installed at the end of the box body near the input shaft. A second bevel gear is installed on the outer wall of the intermediate shaft. The first bevel gear and the second bevel gear are in meshing transmission. A first parallel gear is installed at one end of the outer wall of the intermediate shaft near the second bevel gear. The first output shaft is installed on one side of the intermediate shaft. A second parallel gear is installed on the outer wall of the first output shaft. The first parallel gear and the second parallel gear are in meshing transmission.

[0014] 3. Beneficial effects:
[0015] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:
[0016] The present utility model is reasonably designed. Instead of lubricating the bearing by opening a hole in the bearing seat of the box body for the original oil inlet, since the processing of the bearing seat of the box body is relatively troublesome and the cost is relatively high; an oil seal installation position is added to the oil baffle lubricating ring, and an oil seal is installed, so the sealing effect is better; this oil baffle lubricating ring can not only block oil and slag to play a sealing role but also play a role in lubricating the bearing, which not only saves the processing cycle and cost, greatly enhances the sealing effect, extends the service life of the whole machine equipment, significantly improves the productivity, and makes the processing and installation more convenient.
[0017] It should be noted that the structures not introduced in the present utility model, since they do not involve the design key points and improvement directions of the present utility model, are the same as the prior art or can be implemented by using the prior art, and will not be elaborated here.

[0027] Refer to the attachedFigures 1-3 , a vertical speed reducer with an oil baffle lubrication ring structure. The speed reducer includes a box body 1. Inside the box body 1, a first output shaft 2 is installed. An axle sleeve 3 is fixedly installed outside the first output shaft 2. A bearing 4 is installed inside the box body 1. The first output shaft 2 is rotationally connected to the inside of the box body 1 through the bearing 4. A baffle lubrication ring 5 is welded on the inner side wall of the box body 1. An oil inlet hole 501 is opened on the baffle lubrication ring 5. An oil seal member 6 is installed inside the oil inlet hole 501. The oil inlet hole 501 can be externally connected to an oil pipe. Through the oil inlet hole 501, the bearing 4 is lubricated, and then through transmission, the lubrication effect inside the speed reducer is improved. At the same time, due to the setting of the oil seal member 6, the sealing effect inside the speed reducer is improved, and the oil return at other positions is avoided, resulting in oil leakage.
[0028] In this embodiment, the oil seal member 6 includes an inner oil seal ring and an outer oil seal ring. The inner oil seal ring is installed on the axle sleeve 3, and the outer oil seal ring is installed inside the oil inlet hole 501.
[0029] It should be noted that the sealing effect is improved and oil return is avoided.
[0030] In this embodiment, an input shaft 7 is installed at one end inside the box body 1. A first bevel gear 8 is installed at the end of the input shaft 7. A middle shaft 9 is installed at the end inside the box body 1 close to the input shaft 7. A second bevel gear 10 is installed on the outer wall of the middle shaft 9. The first bevel gear 8 and the second bevel gear 10 are meshed and transmitted. A first parallel gear 11 is installed at one end of the outer wall of the middle shaft 9 close to the second bevel gear 10. The first output shaft 2 is installed on one side of the middle shaft 9. A second parallel gear 12 is installed on the outer wall of the first output shaft 2. The first parallel gear 11 and the second parallel gear 12 are meshed and transmitted. A third parallel gear 13 is installed at the end of the outer wall of the first output shaft 2 far from the second parallel gear 12. A second output shaft 14 is installed on one side of the first output shaft 2. A fourth parallel gear 15 is installed on the outer wall of the second output shaft 14. The third parallel gear 13 and the fourth parallel gear 15 are meshed and transmitted. The input shaft 7, the middle shaft 9, and the second output shaft 14 are all rotationally connected to the inside of the box body 1 through the bearing 4.
[0031] It should be noted that with the cooperation of multiple gears, each shaft system can operate inside the box body 1 through the bearing 4.
[0032] The working principle of the present utility model: By opening the oil inlet hole 501 on the baffle lubrication ring 5 and connecting the oil inlet hole 501 to an oil pipe, the lubricating oil falls on the bearing 4. Under the multi-stage shaft system transmission inside the box body 1, the lubrication effect inside is achieved. By adding the oil seal member 6 inside the oil inlet hole 501, when the oil at other positions enters the first output shaft 2 and flows to the gland, the oil return can be avoided in time, thus avoiding the oil leakage of the equipment.
[0033] The above-described embodiments merely represent certain implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
