Abstract

The utility model discloses a linear rolling guide rail pair which has a strong bearing capacity and can be widely used for mechanical equipment. The linear rolling guide rail pair consists of a sliding block and a guide rail, wherein the guide rail is provided with a triangular guide surface, the sliding block is provided with internal side surfaces which are matched with the two sides of the guide surface of the guide rail, and the internal side surfaces of the two sides of the sliding block are respectively provided with at least a row of cylindrical rollers in a length direction. Since the guide rail with the triangular guide surface is used, the stress on a bearing surface is even; and since the guide surface of the guide rail is in linear contact with the cylindrical rollers, the rigidity of the guide rail is improved, the bearing capacity of the guide rail is improved and the linear rolling guide rail pair can be used for the high-speed reciprocating motion of the moving members of large mechanical equipment.

Description

Straight-line rolling guide set

Technical field

The utility model relates to the guiding pairs technical field, relates in particular to straight-line rolling guide set.

Background technique

Some traditional machinery mostly adopt the slide guide pair to realize the to-and-fro motion of movement parts, because the self character of sliding friction, the slide guide pair is worn and torn easily and is influenced guiding accuracy, and when low speed, can produce creeping phenomenon, more quicken the wearing and tearing of slide guide, significantly reduced guiding accuracy.More existing machinery also have uses the high speed to-and-fro motion that rolling guide-rail pairs is realized movement parts instead, but all be confined to adopt circular guideway to cooperate the rolling guide-rail pairs of ball, though reduced surface friction drag, and the creeping phenomenon when having stopped low speed, but owing to be to contact between the guide surface of guide rail and the ball, add the discontinuity of circular arc supporting plane, cause local deformation and wearing and tearing easily, so rigidity is low, bearing capacity is little, only be fit to be applied in some small mechanical equipments.Thereby influenced applying of rolling guide-rail pairs.

The model utility content

It is big that the technical problems to be solved in the utility model provides a kind of bearing capacity, but popularization and application is in the straight-line rolling guide set of machinery.

The technological scheme that adopts for addressing the above problem: a kind of straight-line rolling guide set, form by slide block and guide rail, it is characterized in that: described guide rail has leg-of-mutton guide surface, described slide block also has the both sides inner side surface that cooperates described guide rail guide surface, and the both sides inner side surface of described slide block all is equipped with at least one row cylinder roller row along its length.

Can be preferably, the both sides inner side surface of described slide block all is equipped with two row cylinder rollers row.

Adopt the beneficial effect that the utility model brought: owing to adopt guide rail with triangle guide surface, make the stressed of supporting plane become even, between the guide surface of adding guide rail and the cylinder roller is that line contacts, frictional force reduces significantly, because of fricative heat very little, improved the rigidity of guiding pairs simultaneously, strengthen the bearing capacity of guiding pairs, can be applicable to the high speed to-and-fro motion of heavy mechanical equipment movement parts.
