Abstract
The utility model is related to a kind of interchangeable variable spool guide rail structures, it includes spool guide rail body, are equipped with guide rail on spool guide rail body top, interchangeable bearing is equipped with centration axis contact position in the spool guide rail body.The utility model is interchangeable, and rolling friction operates steadily, and the service life is longer, and maintenance cost is low.
Description
Technical field
The utility model is related to a kind of guide rail structures, and in particular to a kind of spool guide rail structure.
Background technology
In the prior art, control valve is used for the spool track of variable, mostly uses contact friction and completes, because of motion frequency
Height, spool track and locating shaft abrasion are very fast, and are easy at runtime because of high temperature deformation hair fastener, and are unable to reach variable mesh
, influence service efficiency and the service life of valve.
Invention content
Goal of the invention：The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of interchangeable, rolling
Dynamic friction operates steadily, and the service life is longer, the low variable spool guide rail structure of maintenance cost.
Technical solution：In order to solve the above-mentioned technical problem, interchangeable variable spool guide rail structure described in the utility model,
It includes spool guide rail body, spool guide rail body top be equipped with guide rail, in the spool guide rail body with centering
Axis contact position is equipped with interchangeable bearing.
The interchangeable bearing is needle bearing.
The guide rail is located on the upper side wall thickness direction of spool guide rail body.
The interchangeable bearing is located on the positive direction of spool guide rail body.
Advantageous effect：Compared with prior art, remarkable advantage is the utility model：The utility model structure setting is closed
Original contact friction is changed to rolling friction, such frictional force smaller is more flexible, when safeguarding only by reason using interchangeable bearing
Needle bearing need to be changed, is changed without the whole series, maintenance cost and rate of breakdown are substantially reduced, this product is at low cost,
It operates steadily, the service life is longer.
Description of the drawings
Fig. 1 is the positive structure diagram of the utility model；
Fig. 2 is the right side structural representation of the utility model.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, interchangeable variable spool guide rail structure described in the utility model, it includes spool guide rail
Ontology 1 is equipped with guide rail 2 on 1 top of spool guide rail body, is set with centration axis contact position in the spool guide rail body 1
There is interchangeable bearing 3；The interchangeable bearing 3 is needle bearing；It faces the wall and meditates the upside that the guide rail 2 is located at spool guide rail body 1
On thick direction；The interchangeable bearing 3 is located on the positive direction of spool guide rail body 1.The utility model structure setting is reasonable,
Using interchangeable bearing, original contact friction is changed to rolling friction, such frictional force smaller is more flexible, is only needed when safeguarding
Needle bearing is changed, is changed without the whole series, maintenance cost and rate of breakdown are substantially reduced, this product is at low cost, fortune
Row is steady, and the service life is longer.
The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with
Only it is preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art,
Without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications should also regard
For the scope of protection of the utility model, all undefined components in this embodiment can be implemented in the prior art.
