Embodiment
The utility model is further described with the following Examples.
From Fig. 1 and Fig. 4；A kind of spline guide wheel described in the present embodiment, includes foreign steamer 1 and lubrication groove 2；It is described outer
Wheel 1 is provided with internal spline；Wherein, in figure and internal spline is not drawn into, the lubrication groove 2 is provided with external splines 21；The lubrication groove 2 is sheathed on outer
In wheel 1；
The spline guide wheel also includes bearing 3, jump ring 4 and center connecting shaft 5；The bearing 3 is arranged by jump ring 4
In the inner chamber of lubrication groove 2；One end of the center connecting shaft 5 is connected with bearing 3；The other end of the center connecting shaft 5 is provided with
Bolt 6.
Specifically, the guide wheel described in the present embodiment, in-between bearing 3 coordinate the outer of lubrication groove 2 and the internal spline of external splines
Wheel 1 carries out spline connection, and traditional sliding friction is changed into rolling friction, greatly reduces the friction of foreign steamer 1 and crossbeam, increases
The service life of guide wheel is added.
A kind of spline guide wheel described in the present embodiment, the material of the foreign steamer 1 is nylon.Due to nylon have it is light, excellent
Good self-lubricating property, wearability be good and characteristic of preferably corrosion resistance, thus when being contacted with crossbeam can rub resistance, protect
Demonstrate,prove service life.
A kind of spline guide wheel described in the present embodiment, the material of the lubrication groove 2 is aluminium.Aluminium has inoxidizability, Neng Goufang
Only lubrication groove 2 aoxidizes, and increases the service life of guide wheel.
A kind of spline guide wheel described in the present embodiment, the external splines 21 include spline bottom, spline tooth top 8 and flower
