Abstract
The utility model discloses a silicone oil damper of engines, which comprises a silicone oil damper housing, an inertia wheel, a bearing, a cover plate, silicone oil and a signal gear ring, wherein the signal gear ring is fixed on the silicone oil damper housing which is provided with the inertia wheel internally, the bearing is arranged at the periphery of the inertia wheel, the silicone oil is filled in a gap between the inertia wheel and the housing, and the inertia wheel, the bearing and the silicone oil are sealed inside the silicone oil damper housing by the cover plate. The silicone oil damper has the advantages that the torsional vibration of an engine camshaft is effectively reduced, the function of outputting rotation speed signals of the camshaft is integrated, the installation volume is decreased, the structure is compact, and the installation is convenient, further the weight of the engine is reduced, the quantity of parts is reduced, and the production management cost is decreased.
Description
Technical field
The utility model relates to a kind of silicon oil damper, relates in particular to a kind ofly to reduce engine crankshaft twist vibration and can be convenient to the motor silicon oil damper structure that the collecting crankshaft tach signal is adopted.
Background technique
At present, for reducing the engine crankshaft twist vibration, generally need adopt vibration damper at the engine crankshaft front end, vibration damper generally has rubber shock absorber and silicon oil damper.Enter 21 century, along with the formulation of the Abgasgesetz of increasingly stringent, some electronic controlled diesels develop thereupon.Generally a tach signal dish (signal gear ring) is installed in order to obtain the speed of crankshaft signal at body front end or rear end.The low diesel engine of so original those emission standards wants the discharging upgrading, just need rearrange the component of body front end, so that the installing space of signal panel to be provided.Because the restriction that car load is arranged, motor is difficult to arrange next tach signal dish again sometimes.The bent axle shafting components increases problems such as also can causing the increase of production management cost in addition.
Summary of the invention
At prior art problems, the real novel purpose of this usefulness is to provide a kind of compact structure, good reliability, the motor silicon oil damper structure of integrated reduction engine crankshaft twist vibration, the output of speed of crankshaft signal.
The utility model motor silicon oil damper comprises silicone oil shock absorber shell, flying wheel, bearing, cover plate, silicone oil and signal gear ring, the signal gear ring is fixed on the silicone oil shock absorber shell, flying wheel is installed in the housing, the flying wheel periphery is equipped with bearing, bearing carries bearing with delaying, silicone oil is injected in gap between flying wheel and housing, and cover plate is sealed in flying wheel, bearing, silicone oil in the silicone oil shock absorber shell.Signal gear ring electricity consumption bundle welding manner is fixed on the silicone oil shock absorber shell, and cover plate is sealed in flying wheel, bearing, silicone oil in the silicone oil shock absorber shell by electron beam welding.
The utility model silicon oil damper is simple and compact for structure, and is easy to manufacture, and good reliability is easy to install, can effectively reduce the engine crankshaft torsional oscillation, and the speed of crankshaft signal is provided.This silicon oil damper can not only be realized conventional vibration-damping function, can also need not to install in addition signal panel for the tach signal of the direct collecting crankshaft of sensor.
Specifically, the utlity model has following beneficial effect:
1, effectively reduces the engine crankshaft twist vibration;
2, integrated speed of crankshaft signal output function, compact structure, easy to install;
3, in light weight, reduce engine weight;
4, cost of production is low, is convenient to handling of goods and materials.

In the accompanying drawing: 1-signal gear ring; The 2-cover plate; The 3-silicone oil shock absorber shell; The 4-flying wheel; The 5-bearing; 6-silicone oil
Embodiment
The utility model motor silicon oil damper provides a kind of compact structure, good reliability, the motor silicon oil damper structure of integrated reduction engine crankshaft twist vibration, speed of crankshaft signal output function.This silicon oil damper can not only be realized conventional vibration-damping function, can also be for the tach signal of the direct collecting crankshaft of sensor.
A kind of embodiment of the utility model is as follows, and silicon oil damper is made up of signal gear ring 1, cover plate 2, silicone oil shock absorber shell 3, flying wheel 4, bearing 5, silicone oil 6.Signal gear ring 1 usefulness electro-beam welding method is welded on the silicone oil shock absorber shell 3, and flying wheel 4, bearing 5, silicone oil 6, cover plate 2 are arranged in the housing.Signal gear ring 1, cover plate 2, silicone oil shock absorber shell 3, flying wheel 4 are all made with metallic material, and bearing 5 adopts teflon to make, and between radial and axial between flying wheel 4 and the silicone oil shock absorber shell 3 bearing 5 are arranged all.The flying wheel 4 of silicon oil damper and bearing 5 are built in the inner chamber of silicone oil shock absorber shell 3, and the perfusion of the micro-gap between silicone oil shock absorber shell 3 and flying wheel 4 silicone oil 6, the method that adopts electron beam welding then seals cover plate 2 and silicone oil shock absorber shell 3, the silicone oil that promptly becomes the band signal gear ring device that shakes that slows down.This silicon oil damper not only plays the effect of vibration damping but also play the effect that crankshaft signal is exported.
When installing and using, directly this silicon oil damper is tightened on the bent axle head by bolt, make sensor can directly on the signal gear ring, read the speed of crankshaft signal, and play effects such as reducing the motor torsional oscillation.Reduce engine weight; Reduce number of spare parts, reduce the production management cost.Being suitable for using on the motor, is the silicon oil damper that a kind of ideal engine bent axle is used.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
