Abstract
The invention provides a caterpillar track travel driving device comprising a driving wheel and a track shoe combined in a mutually engaged mode, characterized in that the cross sections of the engaging teeth of the track shoe are of a structure in the shape of a Chinese character 'ao', and the groove bottom surfaces of the engaging teeth are of a concave cambered structure; and the structural shapes of the engaging teeth of the driving wheel are matched with the structural shapes of the engaging teeth of the track shoe, i.e. cambered convex edges matched with the grooves of the corresponding engaging teeth on the track shoe are arranged between every two adjacent engaging teeth of the driving wheel. Compared with the traditional caterpillar track travel driving device, the caterpillar track travel driving device provided by the invention has the advantages in the aspects of track shoe steering, improvement of strength of the engaging teeth, prolongation of service life of the driving wheel and the track shoe, easy running of the device, and the like.
Description
Technical field
The walking that the present invention relates to crawler running machinery drives the field, relates in particular to a kind of track walking driving device that is applicable to crawler crane.
Background technology
The long-term operating mode of rugged mountain region work in the open air of crawler crane requires more and more higher to travel driving unit in the in recent years hydraulic crawler crane generally application in China's large and medium-sized projects, particularly wind-powered electricity generation installation project.The reliability of track walking driving device is had higher requirement for safety and the ease of use of hoisting crane, take special rex De Mage as representative as shown in Figure 1 " wheel tooth plate lead " formula structure easily when turning to, take off chain and Liebherr as shown in Figure 4 " plate gear grooved " formula structure drive wheel can only adopt the shortcoming of the travel driving unit of even number tooth and one-sided guiding unbalance stress to highlight.
Summary of the invention
Purpose of the present invention provides a kind of track walking driving device for existing weak point in the above-mentioned prior art just.Guiding and force-bearing situation when device of the present invention can improve drive wheel and caterpillar block engagement improve reliability and durability that track walking driving device is worked under bad working environments.
Purpose of the present invention can realize by following technique measures:
Track walking driving device of the present invention comprises the drive wheel and the caterpillar block that combine by intermeshing mode; The cross-sectional plane of the engaging tooth of described caterpillar block is the concave shape structure, and the groove floor of this engaging tooth is the concaved circular cambered surface structure; The planform of the engaging tooth of described drive wheel matches with the planform of caterpillar block engaging tooth, namely is being provided with the arc surface fin that matches with the groove of corresponding engaging tooth on the caterpillar block between every adjacent two engaging tooths of drive wheel.
Engaging tooth described in the present invention on the drive wheel and the profile of tooth of the engaging tooth on the caterpillar block are straight line tooth, involute teeth or arc-shaped gear.
Beneficial effect of the present invention is as follows:
Because the active flank of engaging tooth of the present invention contact mesh regional is conducive to the transmission of propulsive effort greater than traditional mesh form; The guide lug of concave shape structure active flank and the driving gear teeth can strengthen the intensity of tooth, improve the stressing conditions of tooth in the propulsive effort transmittance process, have prolonged the service life of caterpillar block and drive wheel.Cambered surface fin in the middle of the cancave cambered surface of caterpillar block engaging tooth and the drive wheel cooperating of convex globoidal not only played the bilateral symmetry directional tagging, but also guaranteed that the face that bears gravity is in surface contact state always, the process that whole driving is rotated seamlessly transits.

The specific embodiment
The present invention is further described below with reference to embodiment (accompanying drawing):
Shown in Fig. 7,8,9, track walking driving device of the present invention comprises the drive wheel 2 and the caterpillar block 1 that combine by intermeshing mode; The engaging tooth of described caterpillar block 1 is the tooth that cross-sectional plane is the concave shape structure, and the groove floor of this tooth is the concaved circular cambered surface structure; The planform of the engaging tooth of described drive wheel 2 matches with the planform of caterpillar block 1 engaging tooth, namely is being provided with the arc surface fin that matches with the groove of corresponding engaging tooth on the caterpillar block 1 between every adjacent two engaging tooths of drive wheel.
More specifically, to be the tooth of concave shape structure be to be that the groove 1-2 of concaved circular cambered surface structure, the teeth 1-3 that is positioned at the groove both sides consist of by the bottom surface in the middle of being positioned to the cross-sectional plane on the caterpillar block described in the present invention 1; Be provided with the arc surface fin 2-2 that matches with the groove of corresponding tooth on the caterpillar block 1 on the drive wheel 2 between per two adjacent two tooth 2-3, tooth top circle is higher than the convex arc surface (the convex arc surface radius equates between caterpillar block concaved circular cambered surface radius and drive wheel teeth) of arc surface fin 2-2.Drive in the process that caterpillar blocks 1 rotate at drive wheel 2, the groove 1-2 of the concaved circular cambered surface structure between the arc surface fin 2-2 in the middle of the wheel body and guide lug has cooperated and leads and bear action of gravitation; Being on the drive wheel 2 is inverted concave shape active flank 2-1 and contacts engagement with the positive concave shape active flank 1-1 that is on the caterpillar block 1, and plays the effect of transmission of drive force.
As shown in figure 10, above-mentioned track walking driving device is installed on the rigid track frame 4 of welding, cooperates the devices such as corresponding caterpillar wheel 3, holder sprocket wheel 5, guide wheel 6, moves thereby drive crawler running machinery by the input power source.In addition, this actuating device also can be used for all-wheel drive (more than the two-wheeled) crawler running machinery.
