Eccentric shaft of pavement roller vibration generator

Abstract

The invention relates to an eccentric shaft of a pavement roller vibration generator. The shaft body of the eccentric shaft is cylindrical; a sliding chute axially parallel to the shaft body is arranged inside the shaft body; a chute opening of the sliding chute is positioned on the circular circumference on one side of the shaft body; the sliding chute is internally provided with an eccentric sliding block; the bottom end of the eccentric sliding block is connected with the bottom of the sliding chute through an extension spring; and the barycenter of the eccentric shaft composed of the eccentric sliding block and the shaft body is positioned on the axle of the shaft body when the extension spring is located at a reset state. The eccentric degree can automatically change along with the rotary speed, so that gentle starting is realized, and the vibration is stopped quickly.

Description

technical field [0001] The invention relates to a vibrating device of a road roller, in particular to an eccentric shaft of the vibrating device of a road roller. Background technique [0002] At present, the vibratory roller is the key equipment in the construction of high-grade highways, dams, building construction, trench foundation, pipeline backfill, etc., and the vibrating part is the key part of the vibratory roller. Most of the existing vibrating devices use the high-speed rotation of the eccentric shaft to achieve vibration. , there are the following defects: 1. It requires a large torque to start the operation of the eccentric shaft. When the power part is suddenly loaded, the load is large, and the loss of the power part is too large; 2. After the power is cut off, due to the inertia, the eccentric shaft will still rotate for a long time Immediately achieves stop vibration. Contents of the invention [0003] The technical problem to be solved by the present inv...
