Abstract
A tension device for a walking pedrail of a tractor mainly comprises a guiding wheel, a crank shaft, a tensioner, a swinging arm, a hitch yoke, a buffer spring, a connecting screw and a positioning tube. The guiding wheel is mounted on the crank shaft which is connected with the front end of the tensioner are through a pin; the back end of the tensioner is connected to the front end of the swinging arm through a pin, and the back end of the swinging arm is connected with the hitch yoke of the compressed buffer spring through a pin; the back end of the buffer spring is hinged on the vehicle frame through the connecting screw of the buffer spring; and the positioning tube is arranged inside the buffer spring. The tension device with the optimal design bears relative small force when impact takes place and the force is relatively stable during the working process. The bearing of the guiding wheel shaft is positioned by the crank shaft body, thereby reducing the accumulation of stress; and the guiding wheel adopts single flange, thereby achieving excellent self-cleaning property and distortion resistant property.
Description
(1) technical field:
The utility model belongs to the trac. field, relates to a kind of tightening device of trac. traveling crawler.
(2) background technology:
At present, the tightening device of the six connecting rod traveling crawlers that China's crawler-tread tractor is commonly used, the track adjusting wheel terrain clearance is little, is subjected to ground shock easily, and track adjusting wheel is the two-wheel edge, and self-cleaning property is relatively poor, and wheel rim is easy to generate torsional deflection; The track adjusting wheel bearing is located by the shaft shoulder, and guide wheel shaft has big stress concentration.In soil-shifting, ploughing with when the heavy load operation such as turning to, the crooked and guiding wheel rim distortion of guide wheel shaft takes place easily.
(3) summary of the invention:
The utility model purpose is to provide that a kind of load-carrying capacity is big, self-cleaning property good, the tightening device of the trac. traveling crawler of long service life.
The utility model adopts following technical scheme to realize above-mentioned purpose: the tightening device of trac. traveling crawler comprises: track adjusting wheel 1, turn axle 2, tensioner 3, swing arm 4, shaft clevis 5, recoil spring 6, connecting screw rod 7 and spacing conduit 8.It is characterized in that: track adjusting wheel 1 is turning on the axle 2 by bearing installation, bearing is located by the axis body that turns that turns axle 2, the vertical distance that turns two axles on the axle 2 is 95 ± 5mm, turn the front end pin joint of axle 2 and tensioner 3, track adjusting wheel 1 is above the preceding pin joint point of tensioner 3, and the vertical distance between the preceding pin joint point axle center of the axle center of track adjusting wheel 1 and tensioner 3 is 45 ± 5mm; The front end pin joint of the rear end of tensioner 3 and swing arm 4, shaft clevis 7 pin joints of the rear end of swing arm 4 and the recoil spring of compression 6, recoil spring 6 installation lengths 675 ± 5mm, the rear end of recoil spring 6 is articulated on the vehicle frame by connecting screw rod 7, spacing conduit 8 places recoil spring 6 inside, and it is 101 ± 5mm that spacing conduit 8 allows the continuation amount of compression after recoil spring 6 is installed.
Track adjusting wheel 1 adopts single-wheel edge structure, and the design of track adjusting wheel disc has the well-distributed hole, and reinforced rib is arranged.
The utility model can reach following good effect: owing to adopted the mechanism that optimizes, whole device is stressed less, when being subjected to impacting, the stressed variation of whole device is little, the vertical distance that turns last two axles of axle is little, makes the track adjusting wheel terrain clearance increase, and has reduced impact, the track adjusting wheel bearing is by turning the axis body location, reduce stress concentration, improved the intensity of guide wheel shaft, track adjusting wheel adopts the single-wheel edge, the former of optimal design and reinforced rib have guaranteed the strength and stiffness of track adjusting wheel.
(4) description of drawings
Fig. 1 is the tensioning device structure figure of the utility model trac. traveling crawler.
(5) specific embodiment
The tightening device of trac. traveling crawler as shown in Figure 1 comprises track adjusting wheel 1, turns axle 2, tensioner 3, swing arm 4, shaft clevis 5, recoil spring 6, connecting screw rod 7 and spacing conduit 8.
Track adjusting wheel 1 is turning on the axle 2 by bearing installation, Bearing support turns the axis body that turns of axle 2 and locatees, the vertical distance that turns two axles on the axle 2 is 95 ± 5mm, turn the front end pin joint of axle 2 and tensioner 3, track adjusting wheel 1 is before tensioner 3 above the pin joint point, and the vertical distance between the preceding pin joint point axle center of the axle center of track adjusting wheel 1 and tensioner 3 is 45 ± 5mm; The front end pin joint of the rear end of tensioner 3 and swing arm 4, shaft clevis 7 pin joints of the rear end of swing arm 4 and the recoil spring of compression 6, recoil spring 6 installation lengths 675 ± 5mm, the rear end of recoil spring 6 is articulated on the vehicle frame by connecting screw rod 7, spacing conduit 8 places recoil spring 6 inside, and it is 101 ± 5mm that spacing conduit 8 allows the continuation amount of compression after recoil spring 6 is installed.Realize the spacing of whole device by spacing conduit 8, cross the dead point when preventing mechanism kinematic.
During tensioned tracks, tensioner 3 elongations promote track adjusting wheel 1 and move forward tensioned tracks; When track adjusting wheel 1 was subjected to impact load, track adjusting wheel 1 was drawn back, and tensioner 3 moves backward, and drive swing arm 4 and swing compression recoil spring 6 backward, thus the buffering of realization.
