How to choose a high speed linear guide

Selection criteria for selecting high-speed guide rails:

1: What is the type of equipment?

2: What is the load weight of the slide?

3: Running speed x meters and seconds? (HDS2 V-type roller guide rail maximum speed 8 m sec) 4: Installation method: single axis double axis gantry?

5: Valid itinerary?

6: Positioning accuracy?

At present, the most popular in the high-speed rolling guide rail is this V-shaped roller guide, this V-shaped roller guide, and even can be integrated with teeth into: V-shaped roller guide rail rack, one with teeth, one for V-shaped roller guide.

The integration of the guide rail and rack naturally eliminates the need for proofreading.

It has been expanded from the application of general processing machinery to the most precise truss manipulator guide rail rack system, gantry manipulator guide rail system, robot seventh-axis guide rail system, and also has a wide range of applications in large gantry cutting machines and welding machines.

In the course of 26 years of development, Kate Precision Machinery has been committed to the product development strategy of high performance, high precision and high rigidity, and has a number of efficient production lines such as mass production rollers, balls, silent and miniature series linear guide pairs, linear modules, etc., and the products are completely comparable to similar products in the United States and foreign countries in terms of performance indicators such as accuracy, rigidity, running speed, load, sealing and life, and have become the leading R&D and production manufacturer of precision rolling linear guide pairs in China.

Look at the design requirements of your own machine and then consider the rest.

Japan's *** Taiwan's cost performance is better, and the cheapness of domestic production depends mainly on your positioning.

Look at the accuracy and ** first, and then look at the model and brand.

The guide rails are made in Taiwan, Japan. Mind choosing Taiwan rails. Specific size and length.

1.Because the flow contact can make the starting friction resistance and dynamic friction resistance very small, it can save energy and easily obtain a higher movement speed.

2.The load increases, but there is no sensitive change in the friction coefficient, so under heavy load, the friction coefficient is very small, and the accuracy remains unchanged for a long time, and the mechanical service life can be maintained for a long time.

3.The linear guide shaft has good interchangeability, easy to install and use, and saves time, and makes the mechanical structure novel, small and light.

4.Save the oil feeding procedures and achieve the purpose of simplifying lubrication and maintenance.

1. Easy to install and easy to interchange.

Due to the use of precision processing technology, the slide rail has high straightness, the installation screw hole error in the slide rail is small, the installation is convenient, and the linear guide rail has interchangeability, and the slider or slide rail can be replaced separately, or even the linear guide rail, which can make the machine achieve high precision again.

2. Greatly reduce the driving power.

Because the friction of the linear guide rail movement is very small, only a small power is needed to make the machine move, which significantly reduces the power loss of the machine, and the heat generated by friction is very small, which is suitable for high-speed, frequent start and reversing moving parts.

3. High working accuracy.

The movement of the linear guide rail is realized by the rolling of the steel ball, not only the friction coefficient is reduced to 1 50 of the sliding guide rail, and the dynamic and static friction resistance curve gap also becomes very small, so that the movement is stable, the impact and vibration are reduced, and the crawling phenomenon is not easy to occur, so the um progressive feed positioning accuracy can be achieved, which is beneficial to improve the response speed and sensitivity of the numerical control system.

4. Strong dustproof and sealing ability.

The linear guide has good anti-production performance, the two ends of the slider are equipped with sealing end covers, and the bottom can be selected with sealing negatives, while the screw holes of the slide rail are equipped with anti-screw hole covers to prevent the accumulation of dust, so as to ensure the life and performance of the product.

5. Simple lubrication structure.

The linear guide is equipped with an oil injection hole on the slider, which can directly inject grease with the grease injection gun, or can be connected to the oil supply pipe to lubricate the automatic oil supply machine, so that its wear is reduced to a minimum, so that the machine can maintain accuracy for a long time.

(1) Self-aligning ability.

The DF(45-°45)° combination from the arc groove can be absorbed by the linear rail slider even if the mounting surface is somewhat deviated through the elastic deformation of the steel ball and the transfer of the contact point during installation, resulting in the effect of automatic self-alignment ability and obtaining high-precision and stable smooth movement.

2) Linear guides are interchangeable.

Due to the strict control of manufacturing accuracy, the size of the linear guide can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off, so some series of precision is interchangeable, customers can order the guide rail or slider according to their needs, and can also store the guide rail and slider separately to reduce the storage space.

3) High rigidity in all directions.

The use of four-row circular arc grooves, with the four-row steel balls and other 45-degree contact angles, so that the steel balls can achieve an ideal two-point contact structure, which can withstand the load from the upper and lower and left and right directions; If necessary, preload can be applied to increase rigidity.

When using a linear guide as a linear guide, the friction coefficient of the linear guide is reduced to that of the sliding guide because the friction mode of the linear guide is rolling friction.

Linear guide rails, also known as slide rails, linear guide rails, and linear slide rails, are used for linear reciprocating motion, and have a higher rated load than linear bearings, and can bear a certain amount of torque, and can achieve high-precision linear motion under high load.

It is used in machine tools (machine tools), engraving machines, handling devices, food machinery, inkjet printing machines, printing machinery, woodworking machinery, LCD panel manufacturing equipment, medical equipment, EDM machines, laser processing machines, screen printing machines, screen printing machines and other reciprocating machinery.

Linear guides are generally used with ball screws.

Ball screws are ideal for converting rotary motion into linear motion, or for converting linear motion into rotary motion.

Ball screws consist of screws, nuts, and balls. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screws, and the significance of this development is to change the bearing from rolling action to sliding action. Due to their low frictional resistance, ball screws are widely used in a variety of industrial equipment and precision instruments.

Ball screws are the most commonly used transmission elements in machine tools and precision machinery, and their main function is to convert rotary motion into linear motion, or torque into axial reciprocal force, while having the characteristics of high precision, reversibility and high efficiency.
