Description

Technical Field

[0001] This utility model relates to the field of commutator technology, and in particular to a wear-resistant commutator. Background Technology

[0002] In the field of modern mechanical transmission, the commutator shaft, as a core component for realizing the conversion of power direction, is widely used in various mechanical equipment, such as automotive transmission systems and industrial automated production lines. Its working principle is to change the direction of power transmission by cooperating with other transmission components to meet the mechanical operation requirements under different working conditions.

[0003] However, existing reversing shafts have problems in actual use. Under frequent reversing operations, the transmission gears of the reversing shaft are prone to wear. As the wear intensifies, it not only leads to a decrease in transmission accuracy, but may also cause problems such as increased noise and vibration in the equipment, which seriously affects the normal operation and service life of the mechanical equipment. Traditional lubrication methods often require frequent manual addition of lubricating oil, which not only increases maintenance costs and manpower, but also further accelerates the wear of the reversing shaft and its related components if lubrication is not timely. Therefore, improvements are needed. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a wear-resistant reversing shaft, including a housing 1, an output shaft 2 rotatably connected to one side of the housing 1, a bevel gear 3 fixedly installed on the outer wall of the output shaft 2, a reversing shaft 4 rotatably connected to one side of the housing 1, a bevel gear 5 fixedly installed at one end of the reversing shaft 4 near the housing 1, an oil dripping pipe 6 fixedly installed inside the top of the housing 1, an oil storage tank 7 fixedly installed at the top of the oil dripping pipe 6, an oil inlet pipe 8 fixedly installed at the top of the oil storage tank 7, a screw cap 9 threadedly connected to the outer wall of the oil inlet pipe 8, a mounting bracket 11 fixedly installed on the outer wall of the oil storage tank 7, and a pre-cut opening through the top of the oil storage tank 7. A reserved hole 12 is provided, and a sliding column 13 is slidably connected inside the reserved hole 12. A base plate 14 is fixedly installed at the bottom end of the sliding column 13. A rubber sealing piston 15 is fixedly installed at the bottom of the base plate 14. A return spring 16 is sleeved on the outer wall of the sliding column 13. A pull block 17 is fixedly installed at the top end of the sliding column 13. The second bevel gear 5 and the first bevel gear 3 mesh with each other. Anti-slip grooves 10 are evenly opened on the outer wall of the cap 9. The mounting bracket 11 is fixedly connected to the housing 1. The rubber sealing piston 15 is slidably connected to the oil dripping pipe 6. The bottom end of the return spring 16 is fixedly connected to the base plate 14. The top end of the return spring 16 is fixedly connected to the oil storage tank 7.

[0023] In this embodiment, an automatic lubrication structure is provided. The oil storage tank 7 stores lubricating oil. By pulling the pull block 17, the movement of the rubber sealing piston 15 is controlled, so that the lubricating oil drips on demand to automatically lubricate the transmission gear part of the reversing shaft 4. This reduces the operation of frequently adding lubricating oil manually, reduces labor input and maintenance costs, and ensures timely lubrication during equipment operation, avoiding the problem of accelerated wear of parts due to untimely lubrication.

[0024] Example 2: As Figures 3-4As shown, a fixing ring 18 is fixedly installed on the top of the oil storage tank 7. A rubber sealing gasket 19 is slidably connected inside the fixing ring 18. A pressure ring 20 is threadedly connected inside the fixing ring 18. A handle 21 is uniformly fixedly installed on the top outer wall of the pressure ring 20. The rubber sealing gasket 19 is slidably connected to the sliding column 13.

[0025] In this embodiment, the fixing ring 18, rubber sealing gasket 19 and pressure ring 20 at the top of the oil storage tank 7 form a sealing structure. The rubber sealing gasket 19 is sleeved on the sliding column 13. By rotating the pressure ring 20, the rubber sealing gasket 19 can be further tightened to enhance the sealing performance of the oil storage tank 7 and prevent lubricating oil leakage.

[0026] The working principle of this embodiment is as follows: When external power is input, it drives the reversing shaft 4 to rotate, and the bevel gear 5 fixed at one end of the reversing shaft 4 rotates accordingly. Since the bevel gear 5 meshes with the bevel gear 3 on the output shaft 2, the rotation of the bevel gear 5 transmits power to the bevel gear 3 through gear transmission, thereby driving the output shaft 2 to rotate, realizing the conversion of power direction and meeting the operating requirements of mechanical equipment under different working conditions. In use, the oil storage tank 7 is connected to the inside of the housing 1 through the oil dripping pipe 6 and is used to store lubricating oil. When it is necessary to replenish the lubricating oil, rotate the cap 9 to open the oil inlet pipe 8 and inject lubricating oil into the oil storage tank 7. Under normal working conditions, the rubber sealing piston 15 is tightly fitted with the oil dripping pipe 6 under the action of the return spring 16 to prevent the lubricating oil from flowing out. After the equipment has been running for a period of time, it is necessary to lubricate the transmission gear part of the reversing shaft 4. First, pull the pull block 17 upward. The pull block 17 drives the slide column 13 to move upward inside the reserved hole 12. The bottom plate 14 at the bottom of the slide column 13 and the rubber sealing piston 15 are then connected. The sealing piston 15 moves upward synchronously, at which time the lubricating oil can slowly drip through the oil dripping pipe 6 to the transmission gear part of the reversing shaft 4 to achieve automatic lubrication. After lubrication is completed, the pull block 17 is released, and under the elastic force of the return spring 16, the rubber sealing piston 15 moves downward again to block the oil dripping pipe 6 and stop the oil dripping. In addition, the fixing ring 18, rubber sealing gasket 19 and pressure ring 20 at the top of the oil storage tank 7 form a sealing structure. The rubber sealing gasket 19 is sleeved on the sliding column 13. By rotating the pressure ring 20, the rubber sealing gasket 19 can be further tightened to enhance the sealing performance of the oil storage tank 7 and prevent lubricating oil leakage.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
