The rubber track has the characteristics of light weight, low vibration, low noise, large adhesion, good ground adaptability, and no damage to the road surface; it is especially suitable for construction in cities.
The basic structure of the rubber track and the steel track is the same. It is usually composed of guide wheels, supporting wheels, driving wheels, supporting wheels, crawlers and walking frames. The main differences and characteristics are:
(1) The rubber crawler is a continuous continuous crawler molded from rubber. The core is reinforced Rubber tracks serieswith fabric and multiple wire ropes. There are crawlers on the outside and transmission parts on the inside. Steel transmission parts are embedded in vulcanized rubber bands. The main parameters of the rubber track are pitch, number of sections, track width, pattern, pattern of embedded metal parts, etc.
(2) The driving wheel is installed on the travel reducer, which is used to wind the track to ensure the mechanical running operation. The driving wheels for the rubber track are of convex tooth shape with a pitch of 128mm. There are bending stresses during crawler work, which can cause fatigue damage to the crawler, so the diameter of the drive wheel is not easy to be too small.
(3) The track roller, supporting roller and guide wheel respectively ride on both sides of the crawler teeth and press against the rubber plane. In order to prevent the rim from being cut and severely damaged by squeezing the rubber, the rim is wider: due to the crawler The teeth are higher, so the wheel body is larger.
