During fastening, fastener is resisted against on the projecting surface of installation base, and the second regulation side plate has certain scope of activities.
The fastener is fastening bolt, is realized and fastened by fastening bolt.Fastener also may be selected trip bolt or its
It can realize the fixture of fastening effect.
Second regulation side plate can left and right translation distance δ, can also the certain angle [alpha] of left-right rotation.
The operating center distance ratio theoretical center of bearing on the first regulation side plate and the second regulation side plate away from it is big when, the
Two regulation side plate skew △ L, △ L<δ, the first regulation side plate are parallel with the second regulation side plate.
The operating center distance ratio theoretical center of bearing on the first regulation side plate and the second regulation side plate is away from hour, and the
Two regulation side plates deflect certain angle β, β to the first regulation side plate direction<α.
A kind of Caterpillar conveyer, there is active roller mechanism as mentioned.
The utility model has advantages below compared with prior art：The utility model is simple in construction, can avoid because of assembling
Drive roll bearings at both ends centre-to-centre spacing difference is caused, the later stage can be avoided when carrying out the anti-deviation regulation of crawler belt, drive roll and crawler belt support
Frame end face forms an angle；Avoid adjusting side plate flexural deformation, cause bearing to bear axial force.Bearing use can be extended simultaneously
In the life-span, the failure of color selector transmission mechanism is reduced, improve the reliability of color selector.

Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As shown in figs. 2 to 4, the active roller mechanism of the Caterpillar conveyer of the present embodiment includes driving pulley 1, driven pulley
2nd, drive roll 5, track bracket 9, the first regulation regulation side plate 6 of side plate 4 and second for being arranged at the both sides of track bracket 9, set respectively
The bearing 3 being placed on the first regulation side plate 4 and the second regulation side plate 6；The first regulation side plate 4 and second adjusts side plate 6 and divided
Not Wei Yu drive roll 5 both ends, the driving pulley 1 and driven pulley 2 are set in turn on the first regulation side plate 4；The shoe
The both sides of belt bracket 9 are respectively equipped with installation base 7, and installation base 7 is welded on track bracket 9, positioned at the left side of track bracket 9
It is right installation base 72 positioned at the right side of track bracket 9 for left installation base 71, the first regulation side plate 4 and second is adjusted
Side plate 6 is connected on installation base 7 by fastener 8 respectively, and the first regulation side plate 4 is fitted in the correspondence of track bracket 9
Side.Because driving pulley 1 and driven pulley 2 and first adjust side plate 4 in the same side, therefore the first regulation side plate 4 need not
It is adjusted.
First regulation side plate 4 is installed against the left lateral sides of track bracket 9, the right side of the second regulation side plate 6 and track bracket 9
Between there is adjustable spacing δ, i.e. the end face of right installation base 72 on the right side of track bracket 9 is higher by the end face distance of the second regulation side plate 6
For δ, after the completion of assembling, the first regulation side plate 4 is fixed, the second regulation side plate 6 can left and right translation distance δ, can also left/right rotation
Dynamic certain angle [alpha].
Embodiment 1
