Abstract
The invention relates to a silicone oil shock absorber. The silicone oil shock absorber comprises a silicone oil shock absorber shell, an inertia block, a cover plate and a bearing belt, wherein the center of the silicone oil shock absorber shell is provided with a through hole in which an engine crankshaft is sleeved; the periphery of the silicone oil shock absorber shell and the cover plate form a circle of cavity; the inertia block is accommodated in the cavity; the inertia block and the silicone oil shock absorber shell are separated axially by the bearing belt; the gap between the inertia block and the silicone oil shock absorber shell is filled with silicone oil; the inertia block, the bearing belt and the silicone oil are sealed in the silicone oil shock absorber shell by the cover plate; and radiating fins are welded on the two sides of the silicone oil shock absorber shell. The silicone oil shock absorber has the advantages that: the silicone oil shock absorber can effectively reduce the tensional vibration of the engine crankshaft, has a compact structure, reduces installation volume and is convenient to install; due to the addition of the radiating fins, not only a radiating effect is achieved, but also a decorative effect is achieved; simultaneously, engine weight, component number and production management cost can be reduced.
Description
Technical field
The invention discloses a kind of vibration damper, especially a kind of silicon oil damper of DENG bent axle.
Background technique
At present, vibration damper mainly comprises rubber absorbers and spring damper, and wherein the damping effect of spring cushion is limited, and spring has been grown the easy deformation inefficacy service time; Rubber shock absorber is to be main vibration damper with frequency modulation, and main purpose is to change the position of point of resonance in the rotating speed district to realize, can only be in specific rotating speed district effectively; Silicon oil damper is that damping function is main vibration damper, with self damping absorbed oscillation energy, all produces effect at point of resonance and off-resonance district.
The general power of engineering machinery with reverse all greatlyyer, the operating mode of working is abominable, like high temperature etc.Rubber element has absorbed too much energy, will soon wear out; And the energy that silicon oil damper absorbs is to distribute with the form of heat, therefore is not easy to lose efficacy.
Summary of the invention
The objective of the invention is existing technology is further improved, a kind of silicone oil vibration damper is provided, its radiating effect under the situation that does not increase volume is better.
According to technological scheme provided by the invention, said silicone oil vibration damper comprises: silicone oil shock absorber shell, inertial mass, cover plate, bearing band, silicone oil shock absorber shell center are the through hole that is inserted in engine crankshaft; Form a circle cavity with cover plate around the silicone oil shock absorber shell; Hold inertial mass in the said cavity, the bearing band is separated with position limit cycle to inertial mass and silicone oil shock absorber shell axially-spaced between inertial mass and silicone oil shock absorber shell; Position limit cycle radially separates inertial mass and silicone oil shock absorber shell; Gap between inertial mass and silicone oil shock absorber shell is marked with silicone oil, through cover plate inertial mass, bearing band, silicone oil is sealed in the silicone oil shock absorber shell, between inertial mass and cover plate, also is separated with position limit cycle; Position limit cycle radially separates inertial mass and cover plate, is welded with radiating fin in the silicone oil shock absorber shell both sides.
Said radiating fin is a circular plate, the intensive groove that has on circular plate.
Said groove is outwards dispersed arrangement around the circular plate center,
Said groove is that long and short groove is alternately arranged.
The structure of said groove comprises the convexity of a slit and a said slit in edge.
Advantage of the present invention is: this motor silicon oil damper can effectively reduce the engine crankshaft twist vibration, and compact structure reduces installation volume, and is easy for installation; Increase radiating fin, both played thermolysis, decorative effect is arranged again, can reduce engine weight simultaneously, reduce number of spare parts, reduce the production management cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is heat radiating fin structure figure.
Fig. 3 is the B-B sectional drawing of Fig. 2.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1; Said silicon oil damper comprises silicone oil shock absorber shell 1, inertial mass 3, cover plate 5, bearing band 4, and silicone oil shock absorber shell 1 center is the through hole 7 that is inserted in engine crankshaft; Form a circle cavity with cover plate 5 around the silicone oil shock absorber shell 1; Hold inertial mass 3 in the said cavity, bearing band 4 avoids inertial mass 3 and silicone oil shock absorber shell 1 axially-spaced both contact to cause wear-out failure.Between inertial mass 3 and silicone oil shock absorber shell 1, be separated with position limit cycle 2, position limit cycle 2 radially separates inertial mass 3 and silicone oil shock absorber shell 1.
Silicone oil is injected in gap between inertial mass 3 and silicone oil shock absorber shell 1, through cover plate 5 inertial mass 3, bearing band 4, silicone oil is sealed in the silicone oil shock absorber shell 1.Between inertial mass 3 and cover plate 5, also be separated with position limit cycle 2, position limit cycle 2 radially separates inertial mass 3 and cover plate 5.
At last, radiating fin 6 is welded on silicone oil shock absorber shell 1 both sides.As shown in Figure 2, said radiating fin 6 is circular plate 6-1, the intensive groove 6-2 that has on circular plate 6-1.Said groove 6-2 outwards disperses arrangement around circular plate 6-1 center, and the length groove is alternately arranged.As shown in Figure 3, said groove 6-2 comprises the protruding 6-4 of a slit 6-3 and a said slit 6-3 in edge, has effectively increased heat diffusion area.
The more original silicone oil vibration damper of the present invention has increased radiating fin 6, can better keep the stability of vibration damper work like this.
