Description

Roller guide rail pair

Technical Field

The invention relates to the technical field of guide rails, in particular to a roller guide rail pair.

Background

The existing linear guide rail, especially the ordinary grade and high grade linear guide rail, has loose parts, tight parts, loose parts before installation and no operation after installation, can hear the sound of the ball when being pushed by hand, the slide block arranged on the machine can not be debugged on site, and can only return to the factory for debugging, thus being troublesome, the slide block of the existing linear guide rail is adjusted before leaving factory, can not be adjusted in use, and can only return to the factory for tightness adjustment, thus being troublesome, most users adopt the slide block replacement mode to ensure normal operation, the small clearance can increase the friction force of the guide rail, the too large clearance can reduce the guide precision of the guide rail, most people can select the slide block with higher precision for smooth and stable operation, such as ultra-precision grade and precision grade, and the cost is much higher, when the sliding block is replaced, the whole sliding block needs to be detached, so that a plurality of parts need to be detached, and great troubles are caused.

The cross guide rail is composed of two guide rails with V-shaped roller paths, a retainer, rolling bodies and the like, the rolling bodies which are arranged in a cross mode reciprocate on the V-shaped roller path surface which is precisely ground, and the cross guide rail has the advantages that: the linear guide rail can bear loads in all directions, high-precision and stable linear motion is realized, the borne loads are far higher than that of a linear guide rail, and the reciprocating linear motion precision of the crossed guide rail is far higher than that of the linear guide rail in a limited stroke. The disadvantages are that: the effective travel of the cross guide is limited and a relatively large range of travel is not allowed as with the linear guide.

The characteristics of the M/V type linear guide rail: can realize high accuracy, steady linear motion, the load that can bear is far higher than linear guide, and the shortcoming is: the effective stroke of the M/V type linear guide rail is limited, a relatively large stroke range can be reserved unlike a linear guide rail, the design of the guide rail pair can realize the relatively large stroke range which can be reserved like the linear guide rail, can realize high-precision and stable linear motion like a V-shaped guide rail, can bear a load far higher than the linear guide rail, can adjust the tightness of a sliding block according to the load condition on an installation site, is easy to produce, and is convenient to install, debug, maintain and replace, and the guide rail pair becomes the current requirement.
