Abstract

The utility model discloses a rubber damping wheel, relates to a damper which is suspended on an automobile chassis and solves the problem of idle running and noises caused by cooperation of a belt and wheels during existing mechanical transmission. The rubber damping wheel comprises a main shaft, a waved sleeve, a rubber body and two metal circular discs, the waved sleeve sleeves the main shaft, the outer surface of the waved sleeve is a waved surface, waves are arranged along the axis direction, the two metal circular discs are disposed at two ends of the main shaft, the metal circular discs are fixedly connected with the main shaft, three to six long holes are uniformly formed in each metal circular disc along a first circumference, eight to twenty round holes are uniformly formed in each metal circular disc along a second circumference, the long holes and the round holes are filled with rubber, the rubber body sleeves the waved sleeve, inner holes of the rubber body are matched with the waved surface of the outer surface of the waved sleeve, and an annular belt groove is formed in the outer circumference surface of the rubber body 3. The rubber damping wheel is used for mechanical transmission.

Description

A kind of rubber shock-absorbing wheel

Technical field

The utility model relates to a kind of wheel for mechanical transmission.

Background technique

When moving in turn in mechanical transmission, belt coordinates with wheel.Existing wheel coordinates with belt, and the material of wheel mostly adopts metal wheel (steel, aluminium or copper etc.), and belt is quality of rubber materials, belt with need to have tightness coordinating of wheel, otherwise easily produce idle running, cause power to run off; Meanwhile, belt and wheel coordinate transmission time, between the two, easily produce noise.

Model utility content

The utility model is the belt and the problem that easily produces idle running and noise coordinating of wheel solving in existing machinery transmission, and a kind of rubber shock-absorbing wheel is provided.

The utility model comprises main shaft, Corrugated Sleeve, rubber body and two rosettes, on main shaft, be set with Corrugated Sleeve, the outer surface wavy surface of Corrugated Sleeve, wave is along axial direction setting, two rosettes are arranged on the two ends of main shaft, rosette is fixedly connected with main shaft, on each rosette, be provided with three～six slotted holes along the first circumference uniform distribution, on each rosette, be provided with eight～20 circular holes along the second circumference uniform distribution, in slotted hole and circular hole, be all filled with rubber, rubber body is sleeved on Corrugated Sleeve, the outer surface wavy surface of the endoporus of rubber body and Corrugated Sleeve matches, the circumferential outer surface of described rubber body is provided with endless-belt groove.

The utlity model has following beneficial effect:

The race coordinating with belt is designed to rubber body by the utility model, and while making the coordinating of belt and wheel, the frictional force of belt and wheel is large, and the two is without too large tightness, and belt is difficult for producing idle running with wheel, and power does not run off; Meanwhile, also reduced belt and wheel coordinate transmission time, noise between the two.
