Description

Slide assembly

The present invention relates to a slide rail assembly, and more particularly to a slide rail, a slider assembly and at least one row of rolling elements. The contact between the rolling element set and the slide rail and the slider is at least a line and a surface contact, which not only increases the rigidity, but also can be matched with the ball in the rolling element group, by the staggered first roller, the second roller and the ball The grouping is a group of rolling elements, which can combine the rigidity of the lifting rail assembly and the convenience of different combinations of various point, line and surface contacts.

With the rapid development of advanced industries, the precision and speed of various types of machinery that the industry relies on are increasingly strict. Transfer machinery, especially the transfer machinery used in the machining of the main machine, requires the use of mechanical components to the linear slides. Currently, the common linear slide assemblies mainly include slide rails, slider assemblies and rolling elements. The slider assembly is sleeved on the slide rail, and the slider assembly and the opposite wall surface of the slide rail interpose the rolling element group, and the roller assembly is used as a spacer between the slide rail and the slider assembly, so that the slider assembly is obtained from the slide rail Smoothly slide on. At present, the rolling elements of the conventional linear slide assembly mainly adopt full-row balls or full-row rollers. The rolling parts of the earliest linear slide assemblies are called full-row balls and have ball linear slides, and also adopt full-row rolling. The column is called the linear slide of the roller, so that when the slider moves on the slide rail, the roller or the roller is cyclically rolled, so that the slider can smoothly move on the slide rail. Due to the rigidity and strength of the linear slide, it depends on the number and size of the balls or rollers and their contact with the slide rails. formula. The use of balls, point contact between the balls and the slide rails, although smooth, but can not carry the weight of the higher machine, so the linear slides of the working machine are rarely used alone. The roller is used, and the roller is in line contact with the sliding rail. The rigidity is higher than that of the ball, which can carry a large weight of the machine. The linear sliding rail of the working machine is used in large quantities, for example, the patent No. I273182 of the Republic of China is configured. Six rows of circulating rollers, each of which is in the same axial direction as a rolling element of a linear slide. If compared with the same specifications, the linear slide of the roller is higher in strength and rigidity than the linear slide of the ball because of the line contact. However, there is still a lack of use of the roller. The linear slide is used for a period of time, or the machine has a collision or other impact accident. The roller will wear on the groove surface of the groove, causing the accuracy error of the machine. The entire linear slide is removed and replaced, and the accuracy is recalibrated, which is quite time consuming and costly.

Conventional linear slide assemblies use two types of rolling elements: balls and rollers. Due to the fact that the balls and rollers are placed on the rails, most of the balls are in point contact and the roller is in line contact. State, regardless of the use of balls or rollers, the rigidity and strength of the slide rails are not as close as the surface contact. In order to improve the rigidity of the slide rails and to meet the lack of greater load bearing capacity, many manufacturers have invested in research and development and developed related products. The relevant prior art is described as follows.

The first conventional technology is a technique of surface contact without balls and rollers. It is embedded in the slider with several wear-resistant pieces with high wear resistance and low expansion coefficient materials (such as ceramic sheets and granite). In order to improve the rigidity of the slide rail by making surface contact with the slide rail, it will not cause precision error due to wear and temperature rise during long-time operation. However, the wear-resistant piece is simply used as a spacer, and it is completely in contact with the surface. On the contrary, there is excessive resistance and the sliding is not smooth, and the lubricating oil is liable to heat up significantly and affect the deformation of other parts. The second conventional technique is a technique in which the full row of balls is combined with the all-column and axial rollers to form a rail assembly and is in contact with the wire. example For example, the Republic of China Announcement No. 395462 and the Patent No. I297752 are all rail assemblies that use a full row of balls and a full row of axial rollers. The third conventional technique is a technique in which a plurality of balls and a plurality of slide rollers assembled in the same axial roller are used in a series of rolling elements to be in contact with the wire. For example, a load-enhancing linear slide disclosed in the Patent No. I333032 of the Republic of China. However, whether it is the second conventional technology, the full-row ball is mixed with the all-column roller assembly, or the third conventional rolling element is a mixture of several balls and several axial rollers. The rail assembly, both of which are only point-to-line contact, the rigidity of the linear slide is still insufficient, and in order to make up for the lack of rigidity, a plurality of rows of rolling members have to be arranged, and the multi-row rolling members occupy a large space. Increasing the volume does not allow the working machine to be downsized.

In view of the above-mentioned all-row balls, or all-row rollers, or a linear slide composed of a plurality of balls mixed with several axial rollers in a full-row rolling element, all of which are point or line contact, and have insufficient rigidity. , or to increase the rigidity of the multi-row rolling elements to increase the rigidity caused by the large volume and assembly inconvenience, and the use of wear-resistant sheets for surface contact, but the sliding is not smooth and the temperature rise and deformation, etc., the new creator Based on years of rich R&D and design experience, we are actively investing in R&D. After continuous design, trial and experiment, we will have the output of this new type of research and development.
