Problems solved by technology

[0004] When the eccentric block rotates, a circumferential centrifugal force will be generated. The vertical centrifugal force in the circumferential centrifugal force will exert a vertical pressure on the main shaft to improve the compaction effect of the steel wheel, but the horizontal centrifugal force in the circumferential centrifugal force will exert pressure on the main shaft. The force in the horizontal direction is applied, and the centrifugal force in the horizontal direction periodically exerts forward and backward forces on the roller through the main shaft, so that the roller shakes back and forth, thereby affecting the driving of the roller

Abstract

The invention discloses an impact steel wheel of a road roller, which belongs to the field of road rollers, and solves the problem that an eccentric block exerts a horizontal upward centrifugal force on the main shaft, thereby affecting the running of the road roller. The wheel body and the main shaft are arranged coaxially and are connected in rotation. The main shaft is rotatably connected with a first eccentric mass and a second eccentric mass, and the first eccentric mass and the second eccentric mass rotate in opposite directions at a constant speed. When the first eccentric block rotates to the lowermost end, the second eccentric block also rotates to the lowermost end, and the main shaft is provided with a driving device for driving the rotation of the first eccentric block and the second eccentric block. The structure of the present invention is reasonable, The first eccentric block and the second eccentric block offset each other's centrifugal force, so that the steel wheel produces a vertical impact instead of a horizontal impact, thereby achieving the purpose of reducing the impact on the running of the road roller.

Description

technical field [0001] The present invention relates to a road roller, and more particularly, it relates to an impact drum of a road roller. Background technique [0002] The road roller is an indispensable construction machine in modern road construction. It uses the weight of the steel wheel to compact the bottom surface. In order to reduce the weight of the steel wheel, facilitate the transition and save costs, the vibrating steel wheel is generally used, and the eccentric block is used to rotate. The centrifugal force exerts periodic shock vibrations on the bottom surface. [0003] At present, now, the Chinese invention patent with the notification number CN204703039U discloses a vibrating circular steel wheel for road rollers, including a main shaft and a main body of the steel wheel. The main body of the steel wheel includes an open cylinder, a left sealing plate and a right sealing plate. The connecting bearing is connected with the left sealing plate, the left eccen...
