Centrifugal clutch for vibration compaction machine

Abstract

In a vibration compaction machine such as a rammer, a lining wear dust is prevented from accumulating inside a clutch drum due to oblique attachment of a centrifugal clutch, such that the input shaft side is high and the output shaft side is low because of a forward tilted posture of the machine body.

Claims

1. A centrifugal clutch for a vibration compaction machine in which a clutch drum is disposed obliquely so that an input shaft side is high and an output shaft side is low in a power transmission unit of a vibration compaction machine for compacting a road surface by an up-down movement of a compaction plate, wherein a plurality of discharge ports for a lining wear dust are provided with a spacing therebetween in a corner section formed by a disk-shaped wall surface of the clutch drum and an annular circumferential surface provided at the circumferential edge section of the wall surface, the discharge ports being formed by cutting out portions of the annular circumferential surface close to the corner section.

2. The centrifugal clutch for a vibration compaction machine according to claim 1, wherein a plurality of discharge ports for a lining wear dust are provided with a spacing therebetween in a corner section formed by a disk-shaped wall surface of the clutch drum and an annular circumferential surface provided at the circumferential edge section of the wall surface, the discharge ports being formed by cutting out portions of the disk-shaped wall surface and annular circumferential surface.
