Abstract
The present invention relates 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, are equipped with interchangeable bearing with centration axis contact position in the spool guide rail body.The present invention is interchangeable, and rolling friction runs smoothly, and the service life is longer, and maintenance cost is low.
Description
Technical field
The present invention relates to a kind of guide rail structures, and in particular to a kind of spool guide rail structure.
Background technique
In the prior art, control valve is used for the spool track of variable, mostly uses contact friction to complete, 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.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of interchangeable, and rolling rubs
It wipes, runs smoothly, 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 of the present invention, it is wrapped
Spool guide rail body is included, guide rail is equipped on spool guide rail body top, is connect in the spool guide rail body with centration axis
Synapsis 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.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: structure of the invention setting rationally, using can
Formula bearing is changed, original contact friction is changed to rolling friction, such frictional force is smaller, more flexible, and when maintenance need to only change rolling
Needle bearing is changed without the whole series, substantially reduces maintenance cost and rate of breakdown, and this product is at low cost, is run smoothly,
The service life is longer.
Detailed description of the invention
Fig. 1 is positive structure diagram of the invention；
Fig. 2 is right side structural representation of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, interchangeable variable spool guide rail structure of the present invention, it includes spool guide rail body
1, it is equipped with guide rail 2 on 1 top of spool guide rail body, being equipped in the spool guide rail body 1 with centration axis contact position can
Change formula bearing 3；The interchangeable bearing 3 is needle bearing；The guide rail 2 is located at the upper side wall thickness side of spool guide rail body 1
Upwards；The interchangeable bearing 3 is located on the positive direction of spool guide rail body 1.Rationally, use is interchangeable for structure of the invention setting
Original contact friction is changed to rolling friction by formula bearing, and such frictional force is smaller, more flexible, and when maintenance need to only change needle roller
Bearing is changed without the whole series, substantially reduces maintenance cost and rate of breakdown, and this product is at low cost, runs smoothly, and is made
Use longer life expectancy.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
Stating is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as guarantor of the invention
Range is protected, all undefined components in this embodiment can be implemented in the prior art.
