Oil supply assembly and linear transmission system using the same

The present invention relates to an oil supply assembly and a transmission system, and more particularly to an oil supply assembly for providing a disturbance effect to a lubricating oil by a disturbance member, and a linear transmission system using the same.

The machine tools produced by domestic players are of good quality and have been well received by users in recent years and have a certain status in the international arena. The export value of machine tools has reached the fifth place in the world. In order to strengthen product competitiveness, it is an inevitable trend to propose more sophisticated and high-speed operation technology. The transmission mechanism in the machine tool is the core of it. There are many ways to operate the transmission, especially linear transmission systems. Among the various linear drive systems, linear guides are the most common, and are widely used in various types of machine tools or other automated industrial production equipment.

Components such as guide rails, sliders and balls are the basic components of linear slides. The guide rail is provided with sliding grooves on opposite sides, and the slider is spanned on the guide rail. The ball is held between the slider and the guide rail to reduce the friction between the slider and the guide rail. As for how to achieve the technique of using the linear slide of the ball, it is conventional to provide a return path in the slider body to guide the ball to perform a recirculation motion in the slider.

In addition, the prior art also further improves the linear slide rail with balls, for example, an oil storage box matching the outer shape of the slider is disposed on the side of the slider, and the oil storage box has lubricating oil. In order to provide lubrication to the balls inside the slider. However, the guide rails of the linear slide rails are often not completely horizontal. For example, the path of the guide rails may be an upward or downward slope. At this time, the lubricating oil in the oil storage tank may not easily flow out due to the influence of gravity (gravity), and thus cannot contact the balls inside the slider. Moreover, when the track itself is erected in a non-horizontal position, the oil storage box is relatively in a non-horizontal state, so that the lubricating oil does not easily flow out to the ball due to gravity (gravity), resulting in a decrease in lubrication effect. The above situation will cause the effect of the ball inside the lubricating oil lubrication block to be inconsistent, causing wear between the slider and the guide rail, and the transmission precision and processing quality of the machining machine tool are greatly reduced.

In view of the above problems, the present invention provides an oil supply assembly and a linear transmission system using the same, thereby solving the problem that lubricating oil of the prior art has insufficient lubrication effect on the internal balls of the slider.

An oil supply assembly according to an embodiment of the present invention is disposed on a guide rail and combined with a slider. Wherein, the slider is reciprocally displaced along the guide rail, and the oil supply assembly is configured to provide a lubricating oil to the slider.

The oil supply assembly comprises an oil storage box, at least one rolling wheel and at least one disturbance member. The oil storage box has a storage tank for storing lubricating oil, and the oil storage box is combined with the sliding block. The rolling roller is pivoted to the oil storage box, and the rolling roller reciprocates along the guide rail and rotates relative to the oil storage box. The agitating member is coupled to the swaying roller, and the agitating member is disposed in the sump, and the agitating member rotates together with the swaying roller to agitate the lubricating oil to flow the lubricating oil to the slider.

A linear transmission system according to an embodiment of the present invention includes a guide rail, a slider and an oil supply assembly. The slider is disposed on the guide rail and reciprocally displaced along the guide rail. The oil supply assembly comprises an oil storage box, at least one rolling wheel and at least one disturbance member, wherein the oil storage box has a storage tank for storing lubricating oil, and the oil storage box is combined with the sliding block. The rolling roller is pivoted to the oil storage box, and the rolling roller reciprocates along the guide rail and rotates relative to the oil storage box. The agitating member is coupled to the tilting roller, and the agitating member is disposed in the reservoir. The agitating member rotates together with the tilting roller and agitates the lubricating oil to cause the lubricating oil to flow to the slider.

The agitating member of the oil supply assembly of the present invention is disposed in the storage tank in which the lubricating oil is stored, and is driven by the swaying roller to rotate the agitating member in the storage tank to agitate the lubricating oil to lubricate the lubricating oil. It has better fluidity in the storage tank, which has the lubricating effect between the slider and the guide rail, and greatly increases the smoothness of the reciprocating displacement of the slider along the guide rail.

Since the oil supply assembly is arranged and actuated by the disturbance member, the fluidity of the lubricating oil can be improved, so that the lubricating oil can flow more easily to the slider to improve the lubrication effect between the slider and the guide rail. Compared with the conventional oil supply assembly, the oil supply assembly of the present invention overcomes the non-horizontal path movement of the slider on the guide rail, and the lubricating oil does not easily flow to the slider due to the influence of gravity, resulting in poor lubrication effect. Problem, the present invention further solves the problem of wear between the slider and the slide rail, and the problem that the slider is not smoothly conveyed on the guide rail.

In addition, the linear transmission system of the present invention does not need to additionally add a power source, and only needs to drive the agitating member to rotate by the driving of the rolling roller. Therefore, the linear transmission system of the present invention does not need to add an additional power source. It can effectively improve the fluidity of the lubricating oil and increase the ease with which the lubricating oil is supplied to the slider.
