What is the principle of the V guide roller guide?

The V-shaped roller rolls on the V-shaped guide rail surface, which is hardened and ground to ensure the rolling of strength and transmission accuracy, which can reach a high linear speed, up to 8m s.

The rolling elements of the roller - the steel ball or tapered rollers in the bearing are not in direct contact with the guide rail, which well prevents the contaminants on the guide rail from contacting the rolling elements, and the bearing has good sealing performance to prevent the pollutants in the air from entering and contacting the rolling elements.

The contact between the V-shaped roller and the V-shaped guide rail belongs to the line contact, and the line and the central axis of the roller are obliquely crossed, and rotate around the central axis at high speed; The contact between this wire and the V-shaped guide rail surface belongs to instantaneous contact, approaching the guide rail surface at high speed, instantaneous contact, and then leaving at high speed; In this way, the "line" of the V-shaped roller continuously "scrapes" the guide rail surface, which can ensure the cleanliness of the guide rail surface.

The V-rail rack and pinion transmission system mainly includes V-rail, V-rail rack, roller, etc., in addition to supporting flanges, lubrication covers, gears, which have the advantages of stable operation, low noise, high-speed operation, and rapid acceleration and deceleration.

1.Faster linear speed, higher acceleration: The rolling of the V-shaped roller on the V-rail surface of the roller can achieve a high linear speed.

2.Lower noise: The V-groove of our roller bearings and the V-flank of the roller V-guide rail have good contour consistency; The smooth rolling of the V-shaped roller on the surface of the V-shaped guide of the roller can greatly reduce the noise during high-speed operation.

3.Suitable for use in harsh environments from dust-free to dusty: The bearing rolling elements in the roller are not in direct contact with the guide rail surface, and the bearing has good sealing; V-guide technology allows the V-shaped rollers to pass through"Scratch"Movement, dust, chips and other impurities are scraped off the V-rail surface, and the V-rail surface is kept clean, which is very suitable for use in harsh environments.

4.The accuracy requirements of the installation reference are reduced: a V-shaped roller in the V-shaped guide roller guide rail system is equivalent to a slider of the ball guide rail, and the contact between the V-shaped roller and the V-shaped guide rail surface of the roller is similar to a single point contact; In this way, the accuracy requirements for the installation datum are greatly reduced, and the assembly is time-saving and labor-saving.

5.Lower maintenance and replacement costs: the V-shaped guide roller guide rail system can replace the worn guide rails or rollers separately, and do not need to replace them all; In the field, by adjusting the eccentric rollers, it is easy to adjust and obtain the required preload.

As a result, the roller guides are less expensive to maintain and replace.

6.The preload can be adjusted at any time: when the roller guide rail is assembled, the concentric roller and the eccentric roller are used together, and the preload between the roller and the guide rail can be adjusted at any time to ensure smooth operation.

7.Longer service life: The roller guide has a long life, and in many cases, it is only necessary to replace the roller and then adjust the eccentricity of the eccentric roller to get the required preload.

Generally speaking, the track is the longest-life component of the entire linear motion system; For the roller guide in good working condition, it is possible to change only the roller.

8.One-piece rack guide: Linear guide, straight or helical teeth can be cut directly on the guide.

V-shaped roller guide rails and heavy-duty roller square guide rails are widely used in the linear transmission of truss robots and the seventh axis of robots. Most linear motion does not require precise positioning, what is needed is accurate positioning, and in terms of accuracy, the requirements are not so high. The roller guide rails of these two are mainly linear contact, with low friction, high transmission speed, low noise and high precision.

V-Roller Guide Only 4 V-rollers are needed, which can be fixed and easy to install. It can withstand light and medium loads. Because the contact between the V-shaped roller and the V-shaped guide rail belongs to the instantaneous contact, it approaches the guide rail surface at high speed, makes instantaneous contact, and then leaves at high speed; In this way, the continuous scratching of the V-shaped rail surface by the V-shaped roller can ensure the cleanliness of the guide rail surface, and there is no need for very complex dust-proof measures, so the V-shaped guide rail has the function of self-cleaning.

This kind of V-shaped guide rail, which is essentially a roller guide, so it is often also called a roller V-shaped guide or V-shaped roller guide, which has a wide range of applications in factory automation projects such as automatic loading and unloading, truss manipulator, etc.

Heavy-duty roller square guide When your load is very large, or the overturning moment is large due to the cantilever being too long, then you need to consider using heavy-duty roller square guide. The main point of the design of the heavy-duty roller square guide is that all the roller boxes are subjected to radial forces, which can exert their maximum performance.

Since all the roller boxes are subjected to radial forces, they can withstand large overturning moments, which is a great advantage for the robot travel axis.

The roller linear guide rail rack and pinion transmission has a large transmission force, fast transmission speed, and any length can be obtained through splicing;

The roller linear guide has the advantages of fast speed, accurate positioning, and ultra-long stroke can be obtained through splicing.

Both roller linear guides and racks and pinions are spliced for extra-long travels, making them ideal for long-stroke applications in factory automation.

The rack is machined on the linear guide, or the rack is assembled on the linear guide, which becomes a one-piece rack guide.

Truss robots, automatic loading and unloading and other factory automation projects, widely used with rack guides.

1. Integral rack guide: linear guide, which can directly cut out straight or helical teeth on the guide rail; In this way, there is no need to design a separate gear drive system.

2. High adaptability to harsh production environment: The V-shaped roller can scrape off dust, chips and other impurities from the V-shaped guide surface through the "scraping" movement, and keep the V-shaped guide surface clean, which is very suitable for use in harsh environments.

3. Faster linear speed: the rolling of the V-shaped roller on the V-shaped guide rail surface can reach a very high linear speed.

4. Reduce the accuracy requirements of the installation reference: in the V-shaped guide rail rack and pinion transmission system, the contact between the V-shaped roller and the V-shaped guide rail surface is only equivalent to the contact between one steel ball and the guide rail surface; In this way, the accuracy requirements for the installation datum are greatly reduced, and the assembly is time-saving and labor-saving.

5. Lower maintenance and replacement cost: The V-shaped guide rail rack and pinion transmission system can replace the worn V-rail or V-shaped roller separately, and it does not need to be replaced.

6. Longer service life: Generally speaking, the V-rail is the longest-lasting component in the whole V-rail rack and pinion transmission system; For the V-rail in good working condition, it is possible to change only the rollers.

Lower noise: V-shaped rollers and V-shaped guide rails with good contour consistency; The smooth rolling of the V-rollers on the V-rail surface greatly reduces the noise during high-speed operation.

Please prepare to clean the guide rail - dry cotton cloth, lubricating oil. The guide rail of the engraving machine is divided into linear guide rail and roller guide rail. Cleaning of linear guides:

First of all, move the laser head to the far right (or left), find the linear guide, wipe it with a dry cotton cloth until it is bright and dust-free, add a little lubricating oil (sewing machine oil can be used, do not use engine oil), and slowly push the laser head left and right several times to let the lubricating oil be evenly distributed. Cleaning of the roller guide rail: move the beam to the inside, open the end covers on both sides of the machine, find the guide rail, wipe the contact between the guide rail on both sides and the roller with a dry cotton cloth, and then move the beam to clean the remaining places.
