Rail arrangement for roller runners

Abstract

The invention provides a guide rail device of an idler wheel slide block. The guide rail device comprises the slide block (2) and a guide rail (1), wherein the slide block (2) can be slidingly arranged on the guide rail (1). The guide rail device is characterized in that inclined planes (11) are respectively arranged at two sides of the guide rail (1); the inclined planes (11) are axially and respectively provided with convex sliding rails (3); each sliding rail (3) is provided with a rolling bearing (4) which can slide along the sliding rail (3); an annular groove is formed in the peripheral face of an outer ring (41) of each rolling bearing (4); the shape of each annular groove is adapted to the shape of the outer surface of each sliding rail (3); and the rolling bearings (4) are respectively fixed with a slide block frame body (22) in the slide block (2) through fixing devices (5). Compared with the prior art, the guide rail device of the idler wheel slide block, disclosed by the invention, has the advantages that a design of a 90-degree right angle is formed between the two inclined planes of the guide rail and a 90-degree radial included angle is correspondingly formed between the rolling bearings at the two sides is adopted to guarantee the optimal stress of the slide block and the sliding rails; the positioning precision is high; the cylindrical rod sliding rails are arranged so that the friction coefficient is reduced and the walking smooth degree of the slide block is very good; and more importantly, the guide rail device of the idler wheel slide block is low in cost, has high loading capability, and is suitable for high-speed application.

Description

technical field [0001] The invention relates to the technical field of sliders and guide rails, in particular to a roller slider guide rail device. Background technique [0002] The slider guide rail is used in the reciprocating motion of the track. It has a higher rated load than the linear bearing, and can bear a certain torque at the same time, and can realize high-precision motion under high load conditions. Inside the slide rail, which cannot be seen by naked eyes, is its bearing structure, which is directly related to its load-bearing capacity through the rolling motion between the slide rail and the slider by the rolling elements. [0003] The existing patent number is CN201110208443.6. The Chinese invention patent titled "A High-speed Roller Guide with Adjustable Gap" proposes a structure. The invention discloses a high-speed roller guide with adjustable gap, which consists of a linear guide and a roller The slider consists of two parts. Among them, the linear guid...
