Shock absorber for silicone-oil belt pulley

Abstract

The invention discloses a hock absorber for a silicone-oil belt pulley, comprising a belt pulley body, wherein the radial inner periphery of the front end face of the belt pulley body is provided with a position seam allowance for externally connecting belt pulley body, the radial outer periphery is provided with an annular inertia block cavity in which an inertia block adaptive to the shape of the inner cavity is arranged, and silicon oil is injected in the gap between the inertia block and the annular inertia block cavity; the back end face of the belt pulley body is provided with an annular heat-radiating groove, the belt pulley body is provided with a centrifugal heat-radiating hole for communicating with the inner cavity of the position seam allowance for externally connecting belt pulley body and the annular heat-radiating groove, and the diameter of the outer ring of the back end face of the belt pulley body is smaller than that of the front end face. The invention not only has compact structure, but also can effectively shorten the length of a diesel engine, thus realizing air convection of the front end face and the back end face of the shock absorber; the hock absorber for the silicone-oil belt pulley can be cooled continuously to enhance the heat radiating effect thereof, thus improving the reliability and prolonging the service life of thehock absorber for the silicone-oil belt pulley.

Description

technical field [0001] The invention relates to a sustainable cooling silicone oil pulley shock absorber. Background technique [0002] With the increase of power and explosion pressure of medium and heavy-duty diesel engines, the requirements for vibration reduction of the crankshaft torsional vibration system of diesel engines are getting higher and higher, so higher requirements are put forward for the vibration reduction effect of the shock absorber, especially the reliability of the shock absorber , when the inertia wheel is properly matched and the viscosity of the silicone oil is constant, the key factor affecting the damping effect and reliability of the shock absorber is the working environment of the shock absorber, among which the heat dissipation problem of the shock absorber is the main factor. The current general silicone oil Shock absorbers rarely have a heat dissipation structure design, and even if there are, it is mainly to increase heat sinks, and air conv...
