Lower two parts tighten together, and the inside of the fuselage main body is provided with a sound-absorbing pad and rubber shock-absorbing layer, the fuselage
The inside of main body is additionally provided with a bearing, and the inside of the bearing is provided with eight balls, the axis hole and vehicle of the bearing
Power transmission shaft is rabbeted.
It is preferred that, the spring contiguous block and fuselage main body are made up of gray cast iron material.
It is preferred that, described two damping springs are herringbone structure.
It is preferred that, eight balls are elastic anti-seismic steel ball.
It is preferred that, the rubber shock-absorbing layer is directly fitted on bearing.
Compared with prior art, the beneficial effects of the utility model are：Haulage vehicle power transmission shaft damping sound arrester
Provided with two damping springs, and damping spring is herringbone structure, and splayed structure stress is more uniform, spring can be made uniform by
Power, spring contiguous block and fuselage main body are made up of gray cast iron material, and gray cast iron material damping performance is good, casting cost
Low, wearability is good, and eight in fuselage main body ball is elastic anti-seismic steel ball, and flexible, shock resistance is stronger, is hardly damaged,
Rubber shock-absorbing layer is directly fitted on bearing, and when power transmission shaft produces vibrations, rubber shock-absorbing layer can play good cushioning effect,
Playing damping effect effectively prevents the destruction of power transmission shaft and its correlated parts, and efficiency rises with the life-span.
