Problems solved by technology

As a result, the shared load at the contact surface on the side of the concave part for engagement is not uniform, so that the amount of deformation of the belt main body made of rubber is greater at the portion corresponding to the distal end side of the driving claw body than at the portion corresponding to the proximal end side. Tendency to be large (cf. Figure 15 the area indicated by b in)

Embodiment approach 1

[0149] like Figure 18 As shown, as the crawler belt 6, the crawler belt with the metal core protrusion 63 provided at only one place in the belt width direction is used. On the drive sprocket 3 side, the disk-shaped member 30 shown by the phantom line is arranged so that it is located on the left and right sides. Sandwich the position of the metal core protrusion 63 and overlap with the moving track of the metal core protrusion 63 when viewed from the side, on the outer peripheral side of the disk-shaped member 30 is provided a protruding form formed from the disk surface to the lateral side. The drive claw body 31.

[0150] In addition, the contact surface of the bulging contact portion 33 on the side of the driving claw body 31 is formed to be located along the left and right sides of the metal core protrusion 63 from the position facing the metal core protrusion 63 . The part that deviates in the belt direction and bulges along the belt circumference.

Embodiment approach 2

[0152] The bulging abutting portion 33 is provided on the opposing contact surface between the engaging concave portion 62 and the drive claw body 31 at a position corresponding to the position between the left and right metal core protrusions 63 along the belt width direction of the crawler belt 6 , The bulging abutting portion 33 is not limited to being provided on the side of the driving claw body 31 as shown in the embodiment, and may be provided on the side of the engaging concave portion 62 .

[0153] In this case, the bulging abutting portion 33 (not shown) provided on the engaging recess 62 side may be formed in the engaging recess 62 in the same shape as that provided on the driving claw 31 side. The front end surface 62b and the rear end surface 62c of the drive claw body 31 face to the front 31b and the rear 31c of the drive claw body 31, corresponding to the positions between the left and right metal core protrusions 63 along the belt width direction.

Embodiment approach 3

[0156] The shape of the bulging abutting portion 33 is not limited to the shape shown in the embodiment, and although not shown, may be, for example, a rectangular shape when viewed from the side, or a shape in which the contact surface bulges in an arc shape. In addition, it may have a rectangular shape in plan view, or a shape in which the contact surface bulges into an arc shape.

Abstract

Engaging recesses (62) engageable with driving claws (31) are formed between cored bars (61) in a belt circumferential direction. A driving sprocket (3) has the driving claws (31) provided in an outer circumferential side of a disk-shaped member (30) overlapped with a moving trace of cored bar projections in lateral side view at predetermined intervals in the circumferential direction of the disk-shaped member (30). The driving claws (31) are projected laterally from a disk surface of the disk-shaped member (30) in a belt width direction intersecting the disk surface of the disk-shaped member (30). The engaging recesses (62) and the driving claws (31) have respective contact surfaces extending in opposition at a distance to each other, and a projecting contact portion (33) is provided on one of the contact surfaces at a position offset in the belt width direction from a position opposed to the cored bar projection (63). The projecting contact portion (33) projects in a direction to reduce a distance to the other of the contact surfaces, compared with the distance between the respective contact surfaces.

Description

technical field [0001] The present invention relates to a crawler-type traveling device, which includes a crawler belt and a driving sprocket. In the crawler belt, metal cores are buried at regular intervals along the belt circumferential direction in a belt main body made of rubber material, and each metal core Metal core projections for roller guidance protrude from the middle part in the belt width direction to the belt inner peripheral surface side, and the drive sprocket provides rotational power in the belt circumference direction to the crawler belt. Background technique [0002] In such a crawler-type traveling device, the rubber belt main body portion between metal cores buried at regular intervals in the circumferential direction of the crawler belt is provided with an engaging concave portion formed so as to be more along the belt width direction than along the belt length. The belt wearing circumferential direction is long, and the drive sprocket that drives the ...
