Embodiment Construction

[0015] figure 1 Among them, the present invention consists of an outer ring 1, a rubber member 2, and a connecting member 3. The connecting member 3 is provided with a spiral annular groove, and the outer ring 1 is provided with a spiral annular groove with opposite rotation directions. The rubber member 2 is located between the outer ring 1 and the connecting member 3. A belt groove can be provided on the outer ring 1 according to needs. The direction of rotation of the spiral ring groove on the connecting piece and the outer ring must be opposite.

[0016] The rubber piece 2 is vulcanized and formed by a mold, and the rubber piece 2 is embedded between the outer ring 1 and the connecting piece 3 by a press-fitting process.

[0017] figure 2 In the inner circumferential surface of the outer ring 1 is provided with spiral annular grooves.

[0018] image 3 In the outer circumferential surface of the connecting member 3 is provided with a spiral ring groove.

Abstract

The invention provides a vibration damper for an engine, comprising an external ring, a connecting piece, and a rubber piece disposed between the external ring and the connecting piece; the external periphery of the connecting piece is provided with a helical annular groove; the external circumference of the external ring is provided with a helical annular groove corresponding to the groove on the connecting piece. The rubber piece is pressed to the space between the external ring and the connecting piece via a press mounting mode, making the external ring, the rubber piece, and the connecting piece form a firm integral body. The vibration damper for an engine can effectively reduce destruction brought by torsional vibration of a crankshaft of the engine, and improve driving comfortableness of conductors and drivers.

Description

Technical field [0001] The invention relates to an automobile engine vibration reduction technology. Background technique [0002] Vibration is inevitable when the engine is running. This is because the gas pressure in the combustion chamber and the inertial force of the moving mass of the crank-connecting rod mechanism are both periodic functions related to the rotation period of the engine crankshaft. Therefore, the torsional moment that causes the crankshaft to rotate, the overturning moment of the engine, the inertial force acting along the center line of the cylinder and the inertial force in the horizontal direction generated by them are also periodic functions. The engine will vibrate in the vertical and horizontal directions under the action of periodically changing forces and moments. Severe vibration will weaken the strength of engine components, increase wear and tear, and reduce service life, and will fatigue operators, hinder the work of surrounding instruments and...
