Problems solved by technology

[0005] However, the existing crankshaft shock absorber still cannot completely eliminate the influence of crankshaft torsional vibration and crankshaft rolling vibration, so that the crankshaft shock absorber still has uneven rotation, resulting in tension fluctuations in the accessory belt driven by it.

Embodiment 1

[0058] Crankshaft shock absorber for in-line 4-cylinder engine

[0059] Such as Figure 9 , 10 As shown, the outer ring of the crankshaft shock absorber in Embodiment 1 is approximately elliptical as a whole, and the inner and outer rings are integrally formed without a rubber damping ring. It can be made by stamping and spinning steel plates.

Embodiment 2

[0061] Crankshaft shock absorber for in-line 4-cylinder engine

[0062] Such as Figure 11 , 12 As shown, the outer ring of the crankshaft shock absorber in Embodiment 2 is approximately elliptical as a whole, the outer ring is connected to the inner ring through a rubber damping ring, and the inner ring is connected to the crankshaft.

Embodiment 3

[0064] Crankshaft shock absorber for in-line 4-cylinder engine

[0065] Such as Figure 13 , 14 As shown, the outer ring of the crankshaft shock absorber in Embodiment 3 is approximately elliptical as a whole, the outer ring is connected to the inner ring through a rubber damping ring, and the outer ring is connected to the crankshaft.

Abstract

The invention provides a crankshaft damper which comprises an outer ring (1) and an inner ring (2). The outer ring (1) is wholly in a non-regular round shape. The crankshaft damper can reduce effect of rolling vibration and torsion vibration of a crankshaft on tension of a front end accessory belt so as to prolong the service life of the belt.

Description

technical field [0001] The invention relates to a crankshaft damper for an engine. Background technique [0002] During the operation of the engine, huge pressure will be generated when the cylinder is ignited and burned, and the pressure is transmitted to the crankshaft through the crank connecting rod mechanism to drive the crankshaft to rotate. Since the instantaneous huge pressure generated by the combustion in each cylinder of the engine will have an impact on its crankshaft, therefore, the crankshaft will produce uneven rotation during the working cycle, and the number of peak angular speeds of rotation corresponds to the number of ignitions in the working cycle. This uneven rotation of the crankshaft is called crankshaft roll. In addition, due to the certain torsional stiffness of the crankshaft, the force acting on the crank throw at the front end will quickly cause the front end of the crankshaft to twist and deform relative to the rear end, and when the force disa...
