A vertical vibrating wheel with a built-in reversing mechanism

Abstract

The invention discloses a built-in vertical vibrating wheel for a reversing mechanism. The built-in vertical vibrating wheel comprises a vehicle frame and a pressing wheel (8), as well as vibration driving components (9), a left vibration chamber (1), an intermediate vibration chamber (2), a gearbox (4), a right vibration chamber (5) and right connecting components (6), which are arranged in the pressing wheel from left to right, wherein the left and right vibration chambers (1 and 5) adopt the structures of independent excitation chambers and fixed in the pressing wheel (8), so that the stressing mode of the vibration wheel is optimized, and the reliability of the vertical wheel is improved; the gearbox (4) is supported on the pressing wheel (8) through a pivoting support (3) and fixedly connected with the vehicle frame, so that the gearbox (4) does not rotate along with the pressing wheel (8), and the supporting structure of the gearbox (4) is greatly simplified.

Description

technical field [0001] The invention relates to a vertical vibrating wheel, in particular to a vertical vibrating wheel with a built-in reversing mechanism, which is suitable for road rollers. Background technique [0002] A road roller is a compacting device consisting of one or more metal cylindrical rollers or rubber tires, which can crush rock, compacted soil, asphalt concrete or gravel by the rolling and / or vibration of the compacting device. The most widely used vibration method in the road roller market is circular vibration, that is, the exciter arranged along the axis of the vibrating wheel rotates periodically to form a periodic centrifugal force. [0003] The disturbance of the circular vibrating wheel in the horizontal direction will cause the peeling of the surface material, while the theoretical horizontal vibration displacement of the vertical vibration is zero, which is conducive to improving the compaction quality of the laminated surface. For circular vibr...

Problems solved by technology

[0005] However, the above scheme ignores the difficulty of assembly at first. The left eccentric shaft, middle eccentric shaft, four vibration bearings and four left vibration bearing seats are first assembled in the left vibrator housing, and then the components are assembled in the steel wheel housing. Heavy is a major difficulty when disassembling the vibrating wheel, which is not conducive to assembly and on-site maintenance

Similarly, the right exciter housing assembly has this problem, and "the gear case is positioned on the right vibrator bearing block and mounted on the end of the right exciter housing", making the whole assembly heavier and field assembly repairable become more difficult

Secondly, in fact, the centrifugal force generated by the rotation of the left eccentric shaft and the middle eccentric shaft needs to be transmitted through the left vibration bearing seat. Similarly, the centrifugal force generated by the rotation of the right eccentric shaft also needs to be transmitted through the right vibration shaft seat. In this way, the centrifugal force transmission route is complicated. , leading to low reliability of the overall structure

Furthermore, the patent intends to reduce the load of the vibration output bearing and improve the life of the vibration output bearing, but the improved vibration output bearing only reduces the load and does not fundamentally solve the problem of the use of the vibration output bearing
