Abstract
The utility model discloses a heavy-duty linear guild-rail pair, comprising guide rails, wherein a slide block is arranged on the guild rails; the two side walls of the guild rails are provided with long grooves; the inside wall of the slide block forms a projection, and three columns of balls are arranged between the two lateral walls of the guild rails and the slide bock respectively. The guild-rail pair has the advantages of simple structure, easy installation and routine maintenance, and greatly increasing of the load capacity of the guild rails.
Description
Technical field
The utility model relates to the guide rail field, and especially ball class guide rail is specially a kind of heavily loaded linear guide pairs.
Background technique
Guide rail is very wide in the application of mechanical field, is a kind of device that can bear, fix, guide shifter or equipment and reduce its friction.Guide rail is often used for the straight reciprocating motion occasion, has the rated load higher than linear bearing.Spherical guide inside is provided with ball, by the ball power of reducing friction, increases sliding effect.But traditional spherical guide load capacity is relatively poor, has influenced the using scope of spherical guide.
The model utility content
The purpose of this utility model provides a kind of heavily loaded linear guide pairs, and is short working life to solve traditional spherical guide, the problem of load capacity difference.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of heavily loaded linear rail, include the guide rail of straight line, be slidingly fitted with slide block on the described guide rail, it is characterized in that: described guide rail two side has elongated slot along the guide rail direction, the position of the corresponding guide rail of slide block madial wall two side elongated slot forms projection, the projection of described slide block can snap in the elongated slot of guide rail, also vertically be provided with three row between described guide rail two side and the slide block respectively and be close to the ball row of slide block inwall and guide rail respectively, wherein, following ball row are positioned on the projection of slide block, between the elongated slot inwall of bottom and guide rail, above-listed ball is located between slide block and the guide rail top.
The utility model is simple in structure, is easy to install and regular maintenance.By each three row of guide rail two side, the balls row of six row altogether, wherein above-listed and following ball row can bear pressure loading and lateral load, and middle ball is listed as can bear tensile load and lateral load, has improved the load capacity of guide rail greatly.Because the ball row are close to slide block inwall and guide rail respectively,, can not cause rolling resistance to increase simultaneously even apply excessive precompression by 2 contacts yet.
Description of drawings
Fig. 1 is the utility model structure front view.
Embodiment
As shown in Figure 1.A kind of heavily loaded linear guide pairs, include the guide rail 1 of straight line, be slidingly fitted with slide block 2 on the guide rail 1, guide rail 1 two side has elongated slot 3 along guide rail 1 direction, the position of the corresponding guide rail of slide block 2 madial walls two side elongated slot 3 forms projection 4, the projection 4 of slide block 2 can snap in the elongated slot 3 of guide rail 1, also vertically be provided with three row between guide rail 1 two side and the slide block 2 respectively and be close to the ball row of slide block 2 inwalls and guide rail 1 respectively, wherein, following ball 5,6 row are positioned on the projection 4 of slide block 2, between elongated slot 3 inwalls of bottom and guide rail 1, above-listed ball 7 is located between slide block 2 and guide rail 1 top.
