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

1230224 '------------------- V. Description of the invention (1) ~ --- [Technical field to which the invention belongs] The present invention relates to linearity with a self-lubricating system Slide rails, and linear slides are generally linear guide mechanisms that provide precise control. They are widely used in robotic arms, industrial machinery, machinery industry, automation equipment, measuring machines and electronic equipment. [Previously, the mechanism is normal and the sliding ball type is as beautiful as the lubricating oil of the slider. It is easy to wear and lubricate and wastes 569481. After that, the lubricating ball is good, but the lubricating effect is good; and technology] It is safe and linear on multiple machines. The slide rails are not damaged. The oil-lubricated slide rails on the ends of the rollers are not easily damaged. The rolling effect of the ball on the surface of the slide rails is poor, and it is not easy to damage the installation space. As shown in other patent No. 1; the oil is in direct contact, although this method will increase because of its need, and because the fiber is equipped with a linear slider. The linear slide is a linear guide. It must be sufficiently greased to run the ball. At present, its lubrication methods can be roughly divided into two types of indirect lubricating beads. As shown in the square ball indirect lubricating ball and the patent No. 5772 3 33, the patented grease lubricating block contacts the surface of the sliding rail, making the lubricating block's The ball rolling path. When the ball passes through the grease, the ball is lubricated by the grease on the rolling path and the lubrication point where the lubricating block is in contact with the slider is changed. The assembly of the lubricating block will increase the long-term production of the slider. The method of directly lubricating the ball is as in the United States & 'It installs oil-containing lubricating substances on the slider body. However, the ball uses the oil contained in the oil-containing substance to directly lubricate the ball directly. The lubricating effect is better than that of the indirect lubricating block or the bead groove. The material is based on the processing difficulty and processing passes of the slider and the manufactured product directly contacts and rubs with the balls, which is easy to cause fiber.

1230224 V. Description of the invention (2) _ The fabric is worn or the fiber is not running smoothly. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Easy, easy to stick to the ball and enter the rolling path. [Objective of the Invention] The purpose of the present invention is to provide a kind of rolling body.丨 No oil leakage effect and can directly lubricate the rail without contact. Ϊ́ ί: ί ΐ i: 1 is to provide-a kind of linear sliding with self-lubricating system ’^… to reduce the frequency of replenishing lubricant during shutdown. [Summary of the invention] As the linear slide rail is widely used in general precision machinery, it is because of the _ ri nian 彳 "several items of fragrant clothing-this-: the trend of the rapid speed of technology, linear slide · also = ^. The problems caused by the above question are caught, and lubrication is the main question. In order to improve the lubrication efficiency, the linear slip system of the present invention is designed to have the function of automatically adjusting the amount of lubricating oil. In the present invention, the self-lubricating system is set in the sliding block combination. ^ The capillary phenomenon of the lubrication path is used to guide the lubricating oil to the lubrication position. Because the oil system is confined in the lubrication path rather than a state of arbitrary flow, the present The oil supply design of the two self-lubricating system can prevent the lubricant from leaking out of the oil circuit formed by the end cover of the prior art = the contact surface with the slider. path,

Ｍ Page 6 1230224 V. Description of the invention (3) And in the oily material of the cover plate, a capillary current path is formed to return to the slippery position space in the cover oil to run, the amount of oil precipitated is slowly moved, and the gas is rolled) Compared with the lubrication Nouri principle, this body pressure is low suction, in order to supply oil into the self-lubrication system, the oil supply direction can also be free from contact with the rolling body. Lubrication diameter with end cap. When there is a small gap like) the oil moving out of the lubricating oil moves the moving body in motion. When this position is recirculated, the recirculation will be linear and the lubrication method is not limited. Therefore, the effect of the present invention is not linear. Add sliding g of oil < through oily material seams or lubricating oil will be mixed. When the equivalent weight is the gross rolling path, the returning fluid turns to the lubricating level, and the direction of the sliding mode is affected by the directional system. In order to enable, there is a sliding block on the rail. The pre-linear slippery phenomenon body; while the center-shift path (the main center of the center diameter of the direct rolling body is unlimited), the oil-supply rolling body is linearly smooth and self-lubricating. Normally installed rolls with seams or lubricating oil for oil retention are normally analyzed. When the linear motion is in the diameter, the lubricating fluid pressure lubricating oil lubricating roller movement is fast-acting non-line lubrication. The rolling track is set in the lubricating system. Therefore, when the slider is in its original position, so when the small gaps and sliding mouths are full of hair, the film phenomenon, holes are precipitated, and the moving body moves at a faster speed than the lubricating factor of the fluid (main oil) in the sliding rail. The system is equipped with oil storage and self-lubricating system, and the internal linear sliding and sticking phenomenon is close to the natural lubrication. (That is to say, the flow rate of the automatic flow to the return flow is slow, so that the moving body is high: the fluid (mainly the air flow) is fast, and it is fast according to the flow difference in the primary position. The rolling elements of the lubricant are set on any side. The oil-containing material does not lubricate itself, and then it is on top of the oil storage device, so the effective stroke

Design a through or exist in the space, measure, and borrow the aforementioned effects; by this, linear sliding can be more extensive. In addition, this cotton thread), high-density acquisition, and in order to further improve the formula of the present invention is for illustration and further, Non-penetration makes the oil-containing material of the hair slippery. Application of the invention is resistant to oil absorption. The clear capillary speed of the present invention is limited to the high-tech oil-containing foam or oil. It can also be used in the slider body of the sliding block combination = to set up an oil storage device 'to increase the lubricating oil storage system to increase the storage and lubrication phenomenon to achieve self-lubrication and increase the lubrication time and time to improve the linear technology and the more accelerated industry. . Materials such as felt, velvet, cotton (or sponge, etc.) can be used because these materials are easy to have capillary phenomenon.
