Abstract
The utility model discloses a crawler walking driving device comprising a driving wheel and a crawler tread that are combined in a mutually engaged manner. The crawler walking driving device is characterized in that cross sections of engaging teeth of the crawler tread are of concave-shaped structures, and the bottom surfaces of grooves of the engaging teeth are of concave-arc structures; and the structural shapes of the engaging teeth of the driving wheel are matched with those of the engaging teeth of the crawler tread, that is, arc ribs matched with the grooves of the corresponding engaging teeth on the crawler tread are arranged between two adjacent engaging teeth of the driving wheel. Compared with the traditional crawler walking driving device, the crawler walking driving device disclosed by the utility model has the advantages of guiding the crawler tread, increasing strengths of the engaging teeth, prolonging service life of the driving wheel and the crawler tread, smoothly turning the device and the like.
Description
Technical field
The walking that the utility model relates to crawler travel machinery drives the field, relates in particular to a kind of track walking driving device that is applicable to crawler crane.
Background technology
The operating mode of the long-term rugged in the open air mountain region work of crawler crane requires increasingly high to travel driving unit in the widespread usage of hydraulic crawler crane in China's large and medium-sized projects, particularly wind-powered electricity generation installation project in recent years.The reliability of track walking driving device is had higher requirement for the safety and the ease of use of hoisting crane, is that the formula structure is prone to when turning to, to take off chain and Liebherr's " plate gear grooved " as shown in Figure 4 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 in representative " the wheel tooth plate is led " as shown in Figure 1 with special rex De Mage.
Summary of the invention
The purpose of the utility model provides a kind of track walking driving device to existing weak point in the above-mentioned prior art just.Guiding and force-bearing situation when the device of the utility model can improve drive wheel and caterpillar block engagement improve reliability and durability that track walking driving device is worked under bad working environments.
The purpose of the utility model can realize through following technique measures:
The track walking driving device of the utility model comprises the drive wheel and the caterpillar block that combine through intermeshing mode; The cross-sectional plane of the engaging tooth of said 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 said drive wheel matches with the planform of caterpillar block engaging tooth, promptly be provided with between every adjacent two engaging tooths of drive wheel with caterpillar block on the arc surface fin that matches of the groove of corresponding engaging tooth.
The engaging tooth described in the utility model 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 tooth.
The beneficial effect of the utility model is following:
Because the active flank of the engaging tooth of the utility model contact mesh regional helps the transmission of propulsive effort greater than traditional mesh form; The guide lug of concave shape structure engages face 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, whole driving rotating process is seamlessly transitted.

The specific embodiment
To combine embodiment (accompanying drawing) to further describe below the utility model:
Like Fig. 7,8, shown in 9, the track walking driving device of the utility model comprises the drive wheel 2 and caterpillar block 1 that combine through intermeshing mode; The engaging tooth of said 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 said drive wheel 2 matches with the planform of caterpillar block 1 engaging tooth, promptly be provided with between every adjacent two engaging tooths of drive wheel with caterpillar block 1 on the arc surface fin that matches of the groove of corresponding engaging tooth.
Say that more specifically the tooth that the cross-sectional plane on the caterpillar block 1 described in the utility model is the concave shape structure is 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 constitute by the bottom surface in the middle of being positioned at; Be provided with between per two adjacent two tooth 2-3 on the drive wheel 2 with caterpillar block 1 on the arc surface fin 2-2 that matches of the groove of corresponding tooth, 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.In drive wheel 2 driven caterpillar tracks plates 1 rotating process, 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 the effect of leading and bearing gravity; 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.
Shown in figure 10, above-mentioned track walking driving device is installed on the rigid track frame 4 of welding, cooperates devices such as corresponding caterpillar wheel 3, track carrying wheel 5, guide wheel 6, moves thereby drive crawler travel machinery through the imput power source.In addition, this actuating device also can be used for multiple-wheel drive (more than the two-wheeled) crawler travel machinery.
