Abstract
The utility model discloses a silicone oil damper shell, which comprises a large basin-shaped shell, a small basin-shaped shell and a ring-shaped cavity, wherein the basin bottoms of the large shell and the small shell are concentrically welded together, the ring-shaped cavity is formed on the inner side of the basin wall of the large shell and the outer side of the basin wall of the small shell as well as at the basin bottom of the large shell, the bonding surface between the basin bottoms of the large shell and the small shell which are concentrically welded together is necessarily sealed, and the basin bottom of the large shell and belt pulley grooves arranged thereon are formed through one-step spinning. The silicone oil damper shell has the advantages that the structure is simple and the sealing performance is good, thereby avoiding the escape of silicone oil and prolonging the service life; the manufacturing procedures are simple, and the damper shell can also serve as a belt pulley, thereby saving the space, simplifying the structure and lowering the cost; and the intensity of the basin bottom of the large shell is higher due to the spin forming, thereby further improving the performance of the silicone oil damper shell.
Description
Technical field
The utility model relates to a kind of housing of motor silicone oil torshional vibration damper, also relates to the method for making this housing.
Background technique
As shown in Figure 3 and Figure 4, coasting body 10 is installed in the silicone oil shock absorber shell 9, is filled with silicone oil in the shock absorber casing 9, vibration damper 7 absorbs vibrational energy by the inertia of coasting body 10 and the damping of silicone oil, reduces the vibration of axle system.The shock absorber casing 9 of sealing injects silicone oil in the shock absorber casing 9 more earlier through vacuum pumping.The housing rigidity that the tratitional technology stretching forms is relatively poor, and vibration damper 7 can produce distortion when operating at full capacity, reduced damping property, and causes silicone oil to leak easily, reduction of service life, even damping effect inefficacy, major accidents such as crankshaft breakdown take place.Bent axle 8 front ends at motor also can be equipped with belt pulley 6 usually except that vibration damper 7, with drive water pump and motor, but such design can take bigger space, and structure is not compact, and the engine torque vibration is big, is not suitable for the front end output power.The housing of the vibration damper of drawing and forming can't realize that the poly Vbelt groove forms at the housing excircle, and vibration damper just can't the double as belt pulley like this, has increased cost, has increased volume.
The model utility content
Technical problem to be solved in the utility model provides a kind of have simple in structure, easy manufacturing, antileakaging silicone oil shock absorber shell.
For solving the problems of the technologies described above, the technical solution of the utility model is: silicone oil shock absorber shell, comprise the big housing of peviform, and the big housing of described peviform comprises at the bottom of the big housing basin that the periphery at the bottom of the described big housing basin is bent with big housing tub wall cylindraceous; The peviform small shell comprises at the bottom of the small shell basin that the periphery at the bottom of the described small shell basin is bent with small shell tub wall cylindraceous; Toroidal cavity, be used to install the coasting body of silicon oil damper, weld together with one heart at the bottom of the described big housing basin and at the bottom of the described small shell basin, form described toroidal cavity at the bottom of described big housing tub wall inboard, the described small shell tub wall outside and the described big housing basin, at the bottom of the described big housing basin and the sealing of the junction plane at the bottom of the described small shell basin.
As optimized technical scheme, the outer circumferential face of described big housing tub wall is provided with pulley groove.
Owing to adopted technique scheme, silicone oil shock absorber shell comprises the big housing of peviform, and the big housing of described peviform comprises at the bottom of the big housing basin that the periphery at the bottom of the described big housing basin is bent with big housing tub wall cylindraceous; The peviform small shell comprises at the bottom of the small shell basin that the periphery at the bottom of the described small shell basin is bent with small shell tub wall cylindraceous; Toroidal cavity, be used to install the coasting body of silicon oil damper, weld together with one heart at the bottom of the described big housing basin and at the bottom of the described small shell basin, form described toroidal cavity at the bottom of described big housing tub wall inboard, the described small shell tub wall outside and the described big housing basin, at the bottom of the big housing basin and weld together with one heart at the bottom of the described small shell basin, and guarantee at the bottom of the described big housing basin and the sealing of the junction plane at the bottom of the described small shell basin, described big housing tub wall and the rotary press modelling of pulley groove that on described big housing tub wall, is provided with; Simple in structure, good seal performance has avoided silicone oil to leak, and has prolonged working life; And manufacturing process is simple, and shock absorber casing double as belt pulley has been saved the space, simplifies the structure, and has reduced cost, and the big housing tub wall intensity of rotary press modelling is higher, has improved the performance of silicone oil shock absorber shell.
