Problems solved by technology

[0003] The present invention solves the problem that the diameter of the front gear of the existing crawler robot is fixed and inconvenient. It can only overcome obstacles whose height is smaller than the radius of the front gear. For some obstacles whose height is greater than the radius of the front gear, the diameter can be bypassed or passed through by building a slope. problem, and then propose a crawler robot gear transmission structure

Abstract

The invention discloses a gear transmission structure of a tracked robot, and relates to a gear transmission structure, in particular to the gear transmission structure of the tracked robot. The problems that the diameter of the front gear of an existing tracked robot is inconvenient to fix, the existing tracked robot can only climb over and overcome obstacles with the height smaller than the radius of the front gear, and some obstacles with the height larger than the radius of the front gear bypass or pass through in a slope building mode are solved. The gear transmission structure comprises a middle transition gear and two variable-diameter gear mechanisms; the middle transition gear is arranged between the two variable-diameter gear mechanisms, and the crawler belt is arranged on the middle transition gear and the two variable-diameter gear mechanisms in a sleeving mode. The invention belongs to the field of gear structure design.

Description

technical field [0001] The invention relates to a gear transmission structure, in particular to a crawler robot gear transmission structure, and belongs to the field of gear structure design. Background technique [0002] Tracks are driven by flexible links surrounding the drive pulley, road wheels, idlers and track rollers. The track is composed of track shoes and track pins. The track pins connect the track shoes to form a track link. There are holes at both ends of the track shoe, which mesh with the driving wheel, and there are inducing teeth in the middle, which are used to straighten the track and prevent the track from falling off when the tank turns or rolls. Improve the firmness of the track shoe and the adhesion between the track and the ground. A robot that uses a crawler as a chassis to walk is called a crawler robot. A crawler robot can adapt to a variety of complex terrains, so it is widely used in field transportation, reconnaissance and other activities. ...
