Description

Technical Field

[0001] This utility model belongs to the field of self-lubricating spindle technology, specifically a self-lubricating spindle assembly. Background Technology

[0002] As we all know, a machine tool is a mechanical device used to manufacture and process workpieces. It changes the shape, size and surface quality of workpieces through processes such as cutting, grinding, drilling, milling and sawing. Machine tools are widely used in various manufacturing industries, such as automobile manufacturing, aerospace, shipbuilding and electronic equipment. The spindle is a shaft on the machine tool. It is usually used to mount cutting tools or cutters and to perform cutting operations on workpieces through rotational motion. Usually, a lubrication device is needed to provide appropriate lubricating oil when the spindle is working, thereby reducing friction between the spindle and the bearings and reducing wear.

[0003] However, traditional machine tool spindle lubrication systems typically rely on timed oil supply or manual operation, which cannot adjust the oil supply and frequency in real time according to actual working conditions. This can lead to untimely lubrication, causing dry friction in the bearings during high-speed rotation, increasing the risk of wear and damage. Furthermore, during machining, the high-speed rotation of the spindle generates vibrations and noise, which are transmitted throughout the machine tool structure, affecting machining quality and the comfort of the operating environment. Therefore, technological improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses a self-lubricating spindle assembly, comprising a shaft sleeve, bearings, a spindle body, and an outer sleeve. The two ends of the spindle body are mounted inside the shaft sleeve via bearings. The outer sleeve is fitted onto the shaft sleeve, and bearings are provided at both ends of the outer sleeve. The shaft sleeve passes through the bearings. An oil reservoir is provided inside the outer sleeve, containing lubricating oil. An oil outlet is provided on the oil reservoir, and an oil inlet is provided on the shaft sleeve. The lubricating oil enters the oil inlet through the oil outlet and lubricates the spindle body.

[0006] Preferably, the outer cylinder includes a mounting base, a compartment, and an oil filling head. Multiple compartments are circumferentially distributed and are mounted on the mounting base at both ends. The mounting base is equipped with bearings.

[0007] Preferably, each compartment includes a side wall, an outer wall, and an inner wall. The outer wall and the inner wall are concentric arc plates. The outer wall is provided with an oil filling head, and the inner wall is provided with an oil outlet at the center. Preferably, the multiple compartments include three compartments, the mounting base is equipped with a synchronous pulley, a synchronous motor is provided on one side of the outer cylinder, the output shaft of the synchronous motor is equipped with a synchronous pulley, and the synchronous motor drives the mounting base to rotate through a synchronous belt.

[0008] Preferably, the shaft is provided with mounting plates at both ends, and the shaft is mounted on external equipment via the mounting plates.

[0009] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention discloses a self-lubricating spindle assembly. When the housing rotates, the lubricating oil inside slides from one end of the housing to the other, passing through the oil outlet. Some of the lubricating oil drips from the oil outlet into the oil inlet, eventually entering the interior of the shaft cylinder and lubricating the bearings and spindle body along the cylinder. It is important to note that since the outer cylinder's rotation is independently driven by a synchronous motor, it can operate periodically, achieving self-lubrication. For longer intervals, lubricating oil can be replenished via an oil filler. Attached Figure Description

[0018] See attached document Figure 1-2A self-lubricating spindle assembly according to this embodiment includes a spindle sleeve 100, bearings 200, a spindle body 300, and an outer sleeve 400. The two ends of the spindle body 300 are installed inside the spindle sleeve 100 via bearings 200. The outer sleeve 400 is sleeved on the spindle sleeve 100. The two ends of the outer sleeve 400 are provided with bearings 200. The spindle sleeve 100 passes through the bearings 200. An oil reservoir 410 is provided inside the outer sleeve 400. The oil reservoir 410 contains lubricating oil and has an oil outlet 411. The spindle sleeve 100 has an oil inlet 110. The lubricating oil enters the oil inlet 110 through the oil outlet 411 and lubricates the spindle body 300.

[0019] The outer cylinder 400 in this embodiment includes a mounting base 420, a chamber 430 and an oil filling head 440. Multiple chambers 430 are circumferentially distributed and are mounted on the mounting base 420 at both ends. The mounting base 420 is provided with a bearing 200.

[0020] Each compartment 430 in this embodiment includes a side wall, an outer wall, and an inner wall. The outer wall and the inner wall are concentric arc plates. An oil filling head 440 is provided on the outer wall, and an oil outlet hole 411 is provided at the center of the inner wall. The multiple compartments 430 in this embodiment include three compartments 430. A synchronous pulley 421 is provided on the mounting base 420. A synchronous motor 422 is provided on one side of the outer cylinder 400. A synchronous pulley 421 is provided on the output shaft of the synchronous motor 422. The synchronous motor 422 drives the mounting base 420 to rotate through a synchronous belt.

[0021] In this embodiment, the shaft cylinder 100 is provided with mounting plates at both ends, and the shaft cylinder 100 is mounted on external equipment through the mounting plates.

[0022] Working principle: In this design, the shaft cylinder 100 is stably installed, and the main shaft 300 rotates freely within the shaft cylinder 100 via the bearing 200. The shaft cylinder 100 is equipped with an oil inlet 110. When the chamber 430 rotates, the lubricating oil in the chamber 430 slides from one end to the other, passes through the oil outlet 411, and some of the lubricating oil drips from the oil outlet 411 into the oil inlet 110, eventually entering the interior of the shaft cylinder 100 and lubricating the bearing 200 and the main shaft 300 along the shaft cylinder 100, thus achieving lubrication. It should be noted that since the rotation of the outer cylinder 400 is independently driven by the synchronous motor 422, it can achieve periodic operation and self-lubrication. For longer periods, lubricating oil can be replenished through the oil filler 440.

[0023] It should be noted that the above-mentioned lubrication by means of lubricating oil and the long working cycle belong to the state and description of self-lubrication. However, the bearing installed on the main shaft 300 of this application is a self-lubricating bearing.

[0024] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
