When in journey by external force, biggish sliding friction can be generated by leading between idler wheel and slide rail, made to lead idler wheel and easily be ground
Damage, and then influence to lead the efficiency of idler wheel, reduce its service life.
Utility model content
The applicant leads roller devices there are sliding frictions that big, easy to wear, the service life is low for above-mentioned existing advance frame
Disadvantage provides the structurally reasonable advance frame of one kind and leads roller devices, and leading is rolling friction between idler wheel and slide rail, from
And reduce abrasion, increase the service life for leading idler wheel.
Technical solution used by the utility model is as follows:
A kind of advance frame leads roller devices, and main shaft is multi-diameter shaft, and the middle part ladder of main shaft is equipped with connection frame, and main shaft is located at
The stepped part of connection frame two sides is equipped with big roller, and two outer ends of main shaft are by bearing and interior are arranged with trundle.
As a further improvement of the above technical scheme:
Bearing, the inner face of bearing and the inner end face contact of stepped hole one, bearing are set in the stepped hole one of the main shaft
Outer end is equipped with retaining ring one, and the inner hole of bearing is matched with the outer diameter of inner sleeve, the inner hole compression fit of inner sleeve and trundle, trundle
Inner face and bearing outer end face are adjacent, and trundle outer end is equipped with retaining ring.
Retaining ring one is arranged on the stepped hole one of main shaft in corresponding groove.
Retaining ring is equipped in the groove of the external cylindrical surface of inner sleeve.
There is gap between the inner face of inner sleeve and the stepped hole two of main shaft.
Inner sleeve outer end is equipped with lubricating cup.
Oil sealing is provided between trundle and main shaft.
The beneficial effects of the utility model are as follows:
Trundle, trundle and guide rail is arranged by bearing at two outer ends of its main shaft and guide rail contact in the utility model
Contact surface is in rolling contact, and it is between the two rolling that in power head progradation, the trundle at both ends is rolled in guide rail contacting surface
Friction, compared to the sliding friction of original contact position, rolling friction is substantially reduced, and contact position is not easy to wear, and idler wheel uses the longevity
Life greatly increases.The idler wheel at the utility model both ends is to separate independent design with the main structure for leading roller devices, works as idler wheel
After abrasion, replacement easy to disassemble.

Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, the main shaft 3 of the utility model is multi-diameter shaft, and middle part stepped part is arranged by bearing
There is connection frame 13, the utility model can be connect by connection frame 13 with cylinder piston rod 16；Main shaft 3 is located at the two of connection frame 13
Side steps portion passes through bearing respectively and is provided with big roller 12, and the utility model is connect by big roller 12 with chain 15；Main shaft 3
The ladder of two outer ends is provided with trundle 1 by bearing 4 and inner sleeve 2.The utility model is mounted on advance frame by trundle 1
On 14 guide rail, trundle 1 can be rolled along guide rail contacting surface.When moving of car is led in the drive of cylinder piston rod 16, this reality
Moved with the novel guide rail under the drive of chain 15 and oil cylinder 16 along advance frame 14, trundle 1 under the support of bearing 4, around
3 central axis of main shaft rolls on guide rail, forms rolling friction between trundle 1 and guide rail.
As shown in Fig. 2, 3 outer end of main shaft is equipped with stepped hole 1 and stepped hole 2 10, the aperture of stepped hole 1 is greater than step
The aperture in hole 2 10.It is provided with bearing 4 in stepped hole 1,4 inner face of bearing abuts the inner face of stepped hole 1, outside bearing 4
Retaining ring 1 is arranged to carry out axially position in end face, and retaining ring 1 is arranged in the stepped hole 1 of main shaft 3 in corresponding groove.
