Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, specifically to a structurally improved support shaft. Background Technology

[0002] A support shaft is a shaft used to support or fix other components, and it is usually made of metal. The main function of a support shaft is to transmit torque and support weight loads. It is commonly found in fields such as machinery, aerospace, and automobiles. Generally, the shaft is hammered into the inner ring of the bearing for a fixed connection.

[0003] Chinese patent CN103075252A discloses a shaft support. It proposes that, in order to minimize friction between the rotor shaft and the shaft support and facilitate rotor shaft rotation, Teflon is typically applied to the contact surfaces of the shaft support and rotor shaft. However, the frictional resistance remains significant, causing considerable inconvenience for gas turbine maintenance and repair. The proposed solution is a shaft support comprising: a first adjusting element and a second adjusting element, one end of which is connected to a base; a first connecting element and a second connecting element, one end of which is connected to the base, the other end of which is connected to the other end of the first adjusting element, and the other end of the second connecting element is connected to the other end of the second adjusting element; and two rollers, each rotatably connected to the middle of the first and second connecting elements. This shaft support significantly reduces the resistance to rotor shaft rotation through rolling friction between the rollers and the rotor shaft, thus facilitating rotor shaft rotation.

[0004] The rolling friction between the rollers and the rotor shaft in the above scheme will still cause frictional loss during bearing operation, reducing the operating efficiency and life of the equipment. The traditional method of manually adding lubricant to the inside of the bearing to reduce frictional resistance during operation is relatively troublesome and inconvenient to operate. Therefore, the existing support shaft equipment lacks a suitable auxiliary mechanism to automatically add lubricant, reduce friction, and improve working efficiency.

[0005] The above-mentioned solutions and existing technologies lack the necessary structural features, requiring improvement and optimization. Therefore, this invention proposes a structurally improved support shaft to address the aforementioned problem. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0028] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figures 1-9 The present invention provides the following preferred embodiments:

[0030] Example 1: An improved support shaft includes a shaft body 1. One end of the shaft body 1 is fixedly mounted in the inner ring of a bearing 2 by hammering. A threaded groove 3 is provided on the shaft body 1, and the threaded groove 3 is connected to a lubrication auxiliary mechanism. The lubrication auxiliary mechanism includes an oil reservoir 401, an oil outlet 402, a filler port 403, a base 404, a connecting spring 405, a pusher plate 406, a soft brush 407, a rubber stopper 408, a mounting screw 409, and a threaded hole 410. The interior of the oil reservoir 401 is designed as a hollow cylindrical structure with an open bottom end. Threaded holes 410 are provided on both sides of the bottom end of the oil reservoir 401. An oil outlet 402 is fixedly installed on one side of the upper end of the oil reservoir 401, and a filler port 403 is provided on the other side of the upper end of the oil reservoir 401. A thread is fixedly installed on the outer wall of the lower end of the oil reservoir 401, and the thread is adapted to the threaded groove on the shaft body 1 for threaded connection, thereby fixing the lubrication auxiliary mechanism to one side wall of the shaft body 1.

[0031] In use, the lubrication auxiliary mechanism is connected to the threaded groove and installed at both ends of the bearing, fixing the position of the bearing on the shaft body and improving the firmness of the connection between the bearing and the shaft body.

[0032] Example 2: The diameter of the front opening of the oil outlet 402 is set to be smaller than the diameter of the pipe of the oil outlet 402. The front opening of the oil outlet 402 is set to protrude forward. A soft brush 407 is fixedly installed around the outer wall of the front opening of the oil outlet 402. One end of the soft brush 407 is embedded in the front end face of the pipe of the oil outlet 402.

[0033] When in use, the brush 407 spreads the lubricating oil flowing from the oil outlet 402 evenly onto the internal structure of the bearing, which helps to lubricate evenly, protect the bearing, and improve the bearing's working efficiency.

[0034] Example 2: The filler port 403 is sealed with the rubber stopper 408, and a ring-shaped protrusion is provided on the outer side of the front end of the rubber stopper 408.

[0035] When in use, the ring-shaped protrusion on the rubber stopper 408 increases the sealing function of the lubricating oil, and the elasticity of the rubber material allows it to better cooperate with the filler port 403 for sealing.

[0036] Example 3: Through holes are provided on both sides of the bottom end of the chassis 404. A connecting spring 405 is fixedly provided on the upper surface of the chassis 404. A push plate 406 is fixedly provided on the upper end of the connecting spring 405. The outer diameter of the push plate 406 is in close contact with the inner wall of the oil storage pipe 401. Under the action of the connecting spring 405, the push plate 406 can push the lubricating oil in the oil storage pipe 401 to flow out from the oil outlet 402 to lubricate the bearing. The mounting screw 409 passes through the through holes on both sides of the bottom end of the chassis 404. The mounting screw 409 is adapted to the threaded hole 410 of the oil storage pipe 401. The mounting screw 409 and the oil storage pipe 401 are threadedly connected to fix the chassis 404 to the bottom end of the oil storage pipe 401.

[0037] When in use, the lubricating oil in the oil reservoir 1 can smoothly and continuously lubricate the bearing under the combined action of centrifugal force and spring thrust when the support shaft is working. This solves the inconvenience of manually adding lubricating oil, reduces the temperature of the bearing during operation, extends its service life, and improves work efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
