[structure and specialty of linear guide rail]
A set of cross roller guide rail includes: four special V-shaped guide rails which are precisely grinded and processed after special heat treatment, and two cross roller cages which are composed of precision rollers and each other. It is a limited linear motion system with high rigidity, high precision and small size. It is widely used in precision machines such as OA machine and its peripheral machines, various measuring devices, printing substrate drilling machine, or the slide parts of optical tester, optical workbench, control mechanism, X-ray device, etc.
2. The cross roller guide is a combination of the cross roller cage and the 90 ° V groove rolling surface set on the special track. By assembling two rows of roller guides in parallel, they can bear the load in all directions perpendicular to the shaft. Moreover, because the preload can be applied simply, the sliding seat mechanism with high rigidity and light action can be obtained.
Long life and high rigidity: the effective contact length of the roller is increased by 1.7 times compared with the previous products by using the unique roller retention method, and the pitch interval of the roller is shorter, the number of rollers is more, the rigidity is increased by 2 times, and the service life is 6 times. Therefore, for the vibration and impact problems that are easy to occur in the linear motion part, safety design can be fully considered.
Smooth movement: in the cross roller guide, each roller is separated by the cage. Because the roller bag in the cage is in face contact with the roller and has good lubricant retention, there is no wear and small friction, so smooth rolling movement can be obtained.
Excellent corrosion resistance: cross roller guide is a stainless steel product with excellent corrosion resistance.
6 easy to install: there are two kinds of installation holes for cross roller guide rail: threaded hole and through hole, so there are two ways to install and fix the guide rail. One is to install the platform on the machine through the threaded hole; the other is to install the bolt on the machine after passing through the counterbore. Therefore, it is not limited by the installation structure, because the internal double track platform constitutes the integrated structure of the platform. The installation structure is very simple, because of the high precision of the installation parts and linear motion, there will be no machining error.

Linear guide rail
1. Linear guide rail, also known as line rail, slide rail, linear guide rail and linear slide rail, is used in the situation of linear reciprocating motion. It has a higher rated load than linear bearing, and can bear a certain torque at the same time. It can realize high-precision linear motion under the condition of high load. It is called linear guideway in mainland China, linear guideway in Taiwan.
2 divided into square ball linear guide, double axis roller linear guide, single axis linear guide.
The function of linear guide is to support and guide the moving parts, and to do reciprocating linear motion in the given direction. According to the nature of friction, linear motion guideway can be divided into sliding friction guideway, rolling friction guideway, elastic friction guideway, fluid friction guideway, etc. Linear bearings are mainly used in automatic machinery, such as machine tools imported from Germany, bending machines, laser welding machines and so on. Of course, linear bearings and linear shafts are matched. The linear guide rail is mainly used in the mechanical structure with high precision requirements. The moving element and the fixed element of the linear guide rail do not use the intermediate medium, but use the rolling steel ball.
4 uses: 1. Linear guide rail is mainly used in automatic machinery, such as machine tools imported from Germany, paper bowl machines, laser welding machines, etc., of course, linear guide rail and linear axis are matched.
2. The linear guide is mainly used in the mechanical structure with high precision requirements. The moving element and the fixed element of the linear guide do not use the intermediate medium, but use the rolling steel ball. Because the rolling steel ball is suitable for high-speed movement, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as tool holder, carriage, etc. If the force acting on the steel ball is too large, the steel ball is subjected to the preload for too long, resulting in the increase of the resistance of the support movement.
5. Use note: the linear guide is a precision part, so it needs to be used with great care. Even if the linear guide with high performance is used improperly, it can not achieve the expected performance effect, and it is easy to damage the linear guide. Therefore, the use of linear guide rail should pay attention to the following:
1) Corrosion prevention: when taking the straight guide rail directly by hand, the sweat on the hand shall be fully washed, and the operation shall be carried out after applying high-quality mineral oil. In rainy season and summer, special attention shall be paid to rust prevention.
2) Keep the environment clean: keep the linear guide rail and its surrounding environment clean. Even if the small dust invisible to the naked eye enters the guide rail, it will increase the wear, vibration and noise of the guide rail.
3) The installation should be careful: the linear guide rail should be careful when it is used and installed, and it is not allowed to punch strongly, to hit the guide rail directly with a hammer, and to transfer the pressure through the rolling body.
4) Installation tools should be suitable: use proper and accurate installation tools for linear guide rail, try to use special tools, and try to avoid using cloth, short fiber and other things.
Cleaning: as one of the core parts of the equipment, the guide rail and linear shaft are used for guiding and supporting. In order to ensure the high machining accuracy of the machine, it is required that its guide rail and straight line have high guiding accuracy and good movement stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing of the processed parts. Based on these, a large amount of smoke and dust will be deposited on the guide rail and linear axis table for a long time
