Problems solved by technology

Since the rotating disk gear is divided and six identical segmented ring gears 30 are used, the worn segmented ring gear 30 needs to be replaced and reassembled for repair. As a ring gear, it is difficult to achieve ideal roundness, and the overall accuracy of the ring gear is poor. , The tooth fit state of the gear deteriorates, and as a result, the durability decreases

Embodiment Construction

[0024] Hereinafter, a preferred embodiment of the structure of the rotating disk of the motor grader of the present invention will be described with reference to the drawings.

[0025] figure 1 It is an external view of a motor grader 100 as an example of a work vehicle, figure 2 is its side view. Such as figure 1 , figure 2 As shown, at the front end of the front frame 106 of the motorized road grader 100, a drawbar 105 is installed to swing freely, and the rotating disk 104 installed on the drawbar 105 can freely slide along the lateral direction. The working machine 102 is configured by supporting the scraper 103 . The drawbar 105 moves up and down through the synchronous expansion and contraction of the lifting drive cylinders 111a and 111b, and tilts up and down through the different expansion and contraction of the lifting drive cylinders 111a and 111b. The forward direction swings left and right. The rotating disk 104 is driven by the hydraulic motor 113, wher...

Abstract

A circle structure of a motor grader excellent in durability at low maintenance cost. For this purpose, the circle structure includes a drawbar (105), at least one guide shoe (213) attached to the drawbar, an integrated ring-shaped circle gear (211) rotatably supported by the guide shoe, a plurality of circle gear mounting bolts (215) placed at equal pitches on a mounting pitch circle of the circle gear, and a circle (104) which is mounted to the circle gear by the circle gear mounting bolts and rotatable with respect to the drawbar.

Description

technical field [0001] The invention relates to a rotating disc structure of a motor grader. Background technique [0002] Motor grader 10 as work vehicle, such as Figure 8 As shown, at the front end of the motor grader 10, a draw bar 16A is freely swingable, and the scraper 12A is slidably supported in the lateral direction by a rotating disc 14A rotatably installed on the draw bar 16A. . The rotating disk 14A has a squeegee holder 14B for supporting the squeegee 12A. The rotating disk 14A has an integrally formed rotating disk gear (not shown). In order to rotate the scraper 12A, the motor grader 10 operates the rotating disk gear via a pinion (not shown) to rotate the scraper 12A to the left and right with respect to the forward direction of the motor grader 10 to perform the required operation. homework. However, since the rotation angle of the squeegee 12A is almost always within a predetermined range, for example, within a range of 90 degrees, a specific point of ...
