Abstract
The invention discloses a three-section rail. The three-section rail comprises a pair of outer rails and a medium rail which is arranged between the pair of outer rails, wherein the medium rail has an I-shaped section formed by a web plate and flange plates at two ends; a boss matched with the side of the medium rail is arranged on the inner side of each outer rail; load balls are arranged between the inner sides of the flange plates and the bosses. The medium rail with the I-shaped section is relatively good in mechanical property and relatively low in material consumption.
Description
Technical field
The present invention relates to a kind of three joint rails, relate in particular to a kind of three joint rails of high-strength supporting capacity.
Background technology
The middle rail of three joint rails has vital effect to load-carrying and the deadweight of slide rail.In increase, the rail sectional dimension can improve lifting capacity, but has increased material usage, manufacturing cost and slide rail deadweight simultaneously.Increase in order to weigh size the relation increased with material, need a kind of improvement of middle rail cross sectional shape.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of three joint rails, comprise a pair of outer rail and be arranged at the middle rail between a pair of outer rail, described middle rail forms an i shaped cross section by the frange plate at web and two ends, described outer rail inboard is provided with the boss coordinated with described middle trackside face, between described frange plate inboard and described boss, is provided with the load-carrying ball.
Further, be respectively arranged with a pair of auxiliary ball between described web both sides and described boss.
Further, offer in the middle of described boss and dodge groove.
Further, described frange plate inboard with offer the ball grooves coordinated with described load-carrying ball on described boss.
Further, described web both sides with offer the ball grooves coordinated with described auxiliary ball on described boss.
Preferably, between described middle rail height a, described frange plate width b, described web height c, described web thickness d, described frange plate thickness e, relational expression is:
a/b＝1.5～3；
d/b＝0.15～0.4；
c/a＝0.5～0.9；
e＝1/2(aa-c)。
Preferably, be respectively arranged with ball retainer between the load-carrying ball of described middle rail both sides and auxiliary ball.
The invention has the beneficial effects as follows:
1, the middle rail of i shaped cross section is taken into account mechanical property and less materials'use amount preferably.
2, the load-carrying ball is born the weight between outer rail and middle rail, and auxiliary ball plays the effect of auxiliary positioning, steady slide rail.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
