Description
Technical field
The utility model relates to a kind of field of torshional vibration damper, particularly relates to a kind of field being arranged on the poly Vbelt groove belt pulley torshional vibration damper of automobile engine crankshaft axle head.
Background technique
Torshional vibration damper is applied on the engine widely, comprises petrol engine and diesel engine; The wheel hub of torshional vibration damper is arranged on the front axle head of engine crankshaft, and belt pulley utilizes the mode of bonding to be connected on wheel hub by vibration isolation rubber circle.When motor runs, whole axle system can produce torsional vibration, and torshional vibration damper to be reached the Conversion of Energy of torsional vibration by the deformation of vibration isolation rubber circle be the effect of heat energy, thus the torsional oscillation intensity of abatement engine shaft system and reduce the amplitude of torsional vibration; And, by changing the rotary inertia of belt pulley and the rigidity of vibration isolation rubber, the natural frequency of vibration and the oscillatory type of whole axle system can be regulated.If the amplitude of the torsional vibration of engine shaft system is not weakened, crankshaft wear aggravation, total noise of centrifuge increase will be caused; Once resonate, also can cause crankshaft breakdown, thus serious accident occurs.
Present auto trend more and more tends to energy saving standard, in the power train of motor car engine, torshional vibration damper is generally single gearing, needs to be equipped with multiple belt pulley to meet transmission demand in overall gearing, cause complete machine weight to increase, can not power conservation requirement be met.The working principle of torshional vibration damper is that heat energy plays the effect of lowering torsional oscillation by shafting torsional oscillation Conversion of Energy, so in actual use, the mode of failure of vibration damper mostly is heat ageing, reduces from causing working life.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides one to have more transmission unit, simultaneously intensity more much higher wedge belt pulley with groove torshional vibration damper.
Technological scheme: described in the utility model pair of multiple wedge slot belt pulley torshional vibration damper, comprise wheel hub, belt pulley and damping ring, described wheel hub is arranged on the front axle head of bent axle, the center hole hole heart of wheel hub and axis are on the same line, described belt pulley is fixed on the outer ring of wheel hub by described damping ring, described belt pulley is two multiple wedge slot belt pulleys, and described pair of multiple wedge slot belt pulley comprises two multiple wedge slots, is symmetricly set on the both sides of pulley centerline side by side; The described two space between multiple wedge slot belt pulley and wheel hub of damping ring press-in, is fixedly connected on the outer ring of described pair of multiple wedge slot belt pulley and wheel hub; Described wheel hub is provided with multiple stiffening rib, and described stiffening rib is evenly distributed on the border of the center hole of described wheel hub.
As preferably, described stiffening rib is shaping by iron casting.
As preferably, described stiffening rib is 12, and circumference uniform distribution is on described wheel hub.
As preferably, described damping ring is yielding rubber circle, adopts adhesive to be bonded on described pair of multiple wedge slot belt pulley and wheel hub.
Working principle of the present utility model is: when engine crankshaft runs up and produces torsional vibration, due to the existence of damping ring, make between two multiple wedge slot belt pulley of torshional vibration damper outer ring and wheel hub, there is a delayed amount when rotated, thus cause the distortion of damping ring, reach and absorb torsional oscillation energy, be converted into damping ring internal heat energy thus effect of reduction torsional vibration of shafting.When damping ring conversion shafting torsional oscillation energy is heat energy own, the stiffening rib that wheel hub is arranged, improving the intensity of product simultaneously, can play the effect of radiating fin, be distributed by the heat of damping ring inside timely, avoid damping ring quick aging, promote the working life of torsional oscillation vibration damping.
How a set of belt pulley is two multiple wedge slot belt pulleys in addition, can provide transmission unit for engine driving system, makes the power train of motor can reduce by a supporting transmission pulley, thus reaches and reduce complete machine weight, more energy-conservation object.
Beneficial effect: belt pulley is set to two multiple wedge slot belt pulley by (1) the utility model, can save a supporting drivign belt wheel system, reduce complete machine weight, reach energy-conservation object; The utility model arranges multiple stiffening rib on wheel hub simultaneously, not only can improve the strength and stability of whole vibration damper, the effect of radiating fin can also be played, when damping ring operational heat, the heat of damping ring inside is distributed, avoid damping ring quick aging, promote the working life of whole torsional oscillation vibration damping; (2) the utility model makes cylinder iron as the material of stiffening rib, utilizes the feature that Thermal Conductivity of Cast Irons energy is strong, timely to damping ring heat radiation, promotes the working life of torsional oscillation vibration damping further; (3) the utility model stiffening rib is 12, and circumference uniform distribution, on described wheel hub, can dispel the heat to damping ring faster.
