Tensioning device for tracked vehicle

Abstract

The invention discloses a tensioning device for a tracked vehicle, comprising an outer sleeve rod which is fixedly mounted on a chassis and is used for providing support; the inner sleeve rod is mounted in the outer sleeve rod in a sliding manner, and a mounting bracket is arranged at the end part of the inner sleeve rod; the tensioning wheel is rotationally arranged on the mounting bracket; the threaded seat is slidably mounted in the outer sleeve rod and used for pushing the inner sleeve rod to slide in the outer sleeve rod; the tensioning lead screw is installed in the outer sleeve rod in a penetrating mode, and a round hole matched with the tensioning lead screw is formed in the outer sleeve rod. The crawler belt tensioning device has the beneficial effects that the structural design that the inner sleeve rod is matched with the outer sleeve rod is adopted, the tensioning lead screw is rotated to be matched with the threaded base, then the inner sleeve rod is driven to move in the outer sleeve rod, the tensioning wheel is pushed to abut against the interior of the crawler belt to be supported, it is ensured that the crawler belt is safe and reliable in the transmission process, the derailing probability is reduced, operation is easy and convenient, and the practicability is high. The adjusting difficulty is low, and the durability is good.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a tensioning device for a crawler vehicle. Background technique [0002] In order to adapt to agricultural production in harsh environments, the crawler transmission structure is often used as the driving mode of the vehicle. In order to ensure the stability of the crawler during the running process and avoid loosening of the crawler after elongation, which affects power transmission, a tensioning structure is usually designed , while the structure of the existing tensioning device is bulky, and it is difficult to adjust manually. At the same time, the processing accuracy of the parts is required to be high. When the error is slightly large, the guide rod is likely to be stuck. In addition, after the crawler is elongated in the later stage, when the guide rod is stretched out under tension, the guide rod is easily bent and deformed, which in turn affects the power ...
