Abstract
Side gap adjusting devices for a floating drive wheel comprise adjusting seats providing penetrating inner holes, adjusting sliding sleeves, composite linings and adjusting bolts. The adjusting seats are fixedly arranged on frames and further arranged outside frame supporting points. The penetrating inner holes are coaxial with supporting point through holes and provided with inner threads on the outer sections thereof. The adjusting sliding sleeves are slidably arranged on the inner sections of the penetrating inner holes and in the supporting point through holes. The composite linings are mounted in the adjusting sliding sleeves and sleeve L-shaped pins. End surfaces of the composite linings are of reversed shapes and abutted against the end surfaces of the adjusting sliding sleeves. Each of the adjusting sliding sleeves is arranged at one end of a connecting rod component. The adjusting bolts are in threaded connection with the penetrating inner holes to be adjustably arranged in the adjusting seats and drive the adjusting sliding sleeves to do ejecting motions towards the connecting rod components, thus the composite linings are driven to move, and in this way side gaps between the end surfaces of connecting rod components and the end surfaces of the composite linings are adjusted. The side gap adjusting devices are simple and reasonable in structure, rapid to adjust anytime, convenient and accurate to adjust, small in occupied space, convenient to mount and maintain and low in production cost.
