Abstract

The present invention relates to the linear guideway with self-lubrication system which includes the oil storage device and the oil supply device. The characteristic of the self-lubrication system is that the oil supply device use capillarity by the inhale-oil matter, therefore can reach the effect of no drip oil and can lubricate the ball direct with no contact. Thereby can increase the effect of lubricate the ball, and lower the frequency of oil resupply.

Description

200521343 V. Description of the invention α) ------.-[Technical field to which the invention belongs] The present invention relates to a linear slide with a self-lubricating system, and the linear slide generally provides a linear guide with precise control. Indexing mechanisms are widely used in robotic arms, industrial machinery, machinery industry, automation equipment, measuring machines and electrical structures. Electricity a and 4 machines [Prior technology] Linear sliders are installed on many machines. The linear slide rail is a direct-lead mechanism, and the linear slide rail must have sufficient grease to lubricate the balls. Fang Jiu> Normal and does not damage the service life. At present, its lubrication method is roughly divided into two types: sliding ball and direct lubricating ball; The indirect ^ formula of the linear slide rail is as shown in the US patents No. 6 1 557 1 7 and No. 57723 33. It is specially designed to add grease-containing lubricating blocks at both ends of the slider to contact the surface of the slide rail. Strict grease lubricates the slide rail first. The rolling path of the ball on the surface. When the ball passes through the rolling path of the ball, the ball is moistened by the grease on the rolling path; therefore, its lubrication effect is poor, and the lubrication point of the lubricating block and the sliding contact It is easy to wear and not easy to replace, and the assembly of the lubricating block will increase the slider: the apprentice wastes installation space. In addition, the method of directly lubricating balls is shown in US Patent No. 56 948 1 1. It installs oil-containing lubricating substances in the slider body, and then directly contacts the lubricating oil with the balls, using the oil contained in the oil-containing substances to directly ^ slide the balls. Although the method of directly lubricating the ball has a relatively smooth lubricating effect, the lubricating effect is good, but it needs to be pasted with a lubricating material at the bottom of the slider or next to the bead groove to lubricate, so it will increase the processing difficulty and processing path of the slider. And manufacturing costs; and because the fiber fabric directly contacts and rubs with the balls, it is easy to cause fibers

'Fiber, quasi-easy to adhere to the ball and enter the rolling path, so that the rolling synthesis described above, Bu, +, as described above> Knowing the technology is necessary to improve and improve [Objective of the invention] Zirun G Ming :: System linearity The purpose of the slide rail is to provide a kind of rolling body. j No oil leakage effect and can directly lubricate without contact. The secondary purpose of the present invention is to provide a multi-rail, which can prolong the time of slip adjustment to reduce the linear slip before the machine ^ 1 N low frequency of replenishing lubricant . [Summary of the Invention] Since linear slide rails are currently widely used in precision machinery, in order to overcome some of the problems caused by the high-speed machinery of the industry and f in the past two years, lubrication is one of the main problems of the order. "-.

^ First of all, in order to improve the lubricating efficiency, the present invention designed the linear sliding self-lubricating system to have the function of automatically adjusting the amount of lubricating oil, and adopted the method of directly lubricating the rolling elements; the present invention sets the self-lubricating system on the sliding block. In the combination, the capillary phenomenon of the lubricating path is used to guide the lubricating oil to the lubricating position. Since the lubricating oil is confined in the lubricating path instead of an arbitrary flow state, the oil supply design of the self-lubricating system of the present invention can avoid the In the prior art, bubbles were leaked out of the oil path formed by the joint surface of the end cover or the cover and the slider. Secondly, in the present invention, an oil-containing material having a capillary phenomenon is used as a lubrication path.

Page 6 200521343 V. Description of the invention (3) A small gap and a lubrication port are provided between the mating surfaces of the cover plate and the end cap, so that the lubricant in the oil-containing material can return to the capillary through the small gap or the lubrication port to return to the capillary. Turn path. When the oil-containing material is full of lubricating oil, an oil film will naturally occur in the small gaps or lubrication ports in the lubrication position space (that is, the capillary phenomenon is automatically formed). The lubricating oil will precipitate along the reserved through hole and flow to the return turning path To lubricate the rolling elements. When the linear sliding rolling body moves at a slower speed, the amount of oil precipitated is the amount of lubricating oil normally precipitated by the capillary phenomenon, and the slow moving rolling body is lubricated with this amount of oil; and when the linear sliding rolling The body is moving at high speed. When the rolling body moves in the rolling path, the fluid (mainly gas) in it will move. At this time, the fluid (mainly air flow) in the return turning path is more stable than the fluid in the lubrication position (mainly (Lubricating oil) is fast. According to Bernoulli's principle, the fluid pressure in the return turning path is lower than the fluid pressure in the lubricating position. The lubricating oil in the lubricating position will be quickly sucked out due to the pressure difference to enter. The return steering path directly lubricates the rolling elements; therefore, the self-lubricating system of the present invention can automatically adjust the amount of lubricating oil supplied according to the moving speed of the rolling elements of the linear slide, and the lubrication method is a non-contact direct lubrication of the rolling elements. There is no directional restriction on the oil supply method. No matter whether the linear slide rail is installed in any direction, oil supply and lubrication can be performed without any restrictions; No contact with the rolling elements, it will not affect the smooth rolling of the rolling elements. Next, in order to make the linear sliding self-lubricating system have the function of self-lubricating and extend the lubrication time, the present invention designs an oil storage device in the self-lubricating system, and then in order to achieve an effective stroke without shortening the linear slide, the self-lubricating system The oil storage device is set on the inner side of the slider body of the sliding block combination of the linear sliding block. Therefore, the axial length of the sliding block combination is not increased, so the effective stroke of the linear sliding block.
