REXROTH guide slider basic requirements of design

Of the geometric accuracy, motion precision and positioning accuracy requirements are high precision guide (such as nc machine tools and measuring machine slideway), when the

design should follow the following principles:

1. REXROTH the slider, STAR slippery course error compensation principle satisfy the following three requirements, in order to make guide system implementation error mutual

compensation:

(1) guide rail link between must set middle elastic, such as roller plastic belt (film) or fluid membrane etc.

(2) guide rail between must have plenty of preloaded force, in order to compensate contact error.

(3) of guide rail manufacturing error should be less than among elastomer (units) deformation. Details can be landing our website: http://www.kepucd.com we will provide you with

more and better service

2. Rexroth bearings, STAR slide block precision non-interference principle

Manufacture and use various precision of guide rail affection to each other just easy to get a higher precision. Such as: rectangular guide of straight sex and lateral guide

line in manufacturing sexual affection to each other; Flat - V guide combination guide horizontal dimensional change does not affect the guide work precision.

3. REXROTH ball screw, STAR ball screw dynamic and static friction factor close principle

Design guide rail pair should make guide surface move, static friction factor be as close as possible, in order to get high repositioning precision and low speed stability, ball

rail system, set pack plastic board or post the ordinary sliding guide rail, plastic small friction factor and static, frictional factor close.

4. REXROTH guide rail pair fits the principle of automatic esther

To make high precision guide rail, must make guide rail pair have automatic post close properties. Horizontal guide can rely on motion the weight of components to post close,

Other guide it must add spring force or roller pressure makes its post close.

5. REXROTH slider full contact principle

Fixed length guide must ensure move guide in the two largest travel limit position, and fixed guide full-length contact (no more than the fixed guide rail), in order to assure

in contact process guide rail pair always full contact.

6. STAR slide block REXROTH slider compensating force deformation and thermal deformation principle

Guide and its supporting pieces of stress or a change in temperature, and its supporting design guide it, and strive to make its deformation after be required shape. If the beam

gantry machine slideway, made in the convex to compensate for spindle box (or cutter) weight caused by bending deformation.
