Abstract
The utility model discloses a silicon oil damper, comprising an outer shell which is formed by completely machining a metal plate, wherein the outer shell is provided with an annular cavity, the end part of the inner side of the annular cavity is outwards protruded along the axial direction and then inwards extended along the radial direction for forming a supporting end face, one side, provided with the supporting end face, of the outer shell is provided with a cover plate, a first annular welding ring and a second annular welding ring are respectively arranged between the cover plate and the end part of the outer side of the annular cavity of the outer shell as well as between the cover plate and the supporting end face, a closed chamber is formed between the cover plate and the annular cavity, an inertia ring is arranged in the chamber, and fluid silicon oil is filled in a gap formed by the inertia ring and the chamber. The silicon oil damper is simple in structure and reasonable in design, a structural member adopts a metal plate, and the outer shell and the sealing end cover are fixed in a welding manner, so that the integral structure is convenient, the working procedures of manufacturing and machining are reduced, a great deal of materials are saved, the manufacturing cost and the machining cost are reduced, and the subsequent installation and use are also convenient.
Description
Technical field
The utility model relates to a kind of vibration damper, especially relates to a kind of silicon oil damper.
Background technique
In known technical field, torshional vibration damper, it is viscosity torsional oscillation deflate device, in general basic structure is a housing, the working room that oscillation ring is wherein installed and fills viscosity damping medium, vibration support ring is slidably mounted in the narrow slit in working room, in gap between oscillation ring and working room, be full of the full-bodied silicone oil as damping medium, then pass through a radially flange for built-in installation, annular deflate device outer cover is fixedly mounted on and needs vibration damping rotatable parts end, as axle, under most service condition, generally be arranged on piston type compressed machine crankshaft.Existing silicon oil damper structural member is comparatively complicated, installs and manufactures inconvenience, and operation is many, and manufacture cost is high, and spillage of material is serious.
Model utility content
Technical problem to be solved in the utility model is: a kind of silicon oil damper is provided, and to solve, the structural member manufacturing process of existing silicon oil damper is many, cost is high; The problem that assembling is complicated, stock utilization is low.
For addressing the above problem, the technical solution of the utility model is: a kind of silicon oil damper, comprise the frame entirely being formed by sheetmetal working, described frame has annular cavity, the inner end of described annular cavity radially stretches in mutually after outwardly convex vertically again and forms supporting end face, a side that is provided with supporting end face at described frame is provided with cover plate, between described cover plate and the outboard end of annular cavity, between cover plate and supporting end face, be respectively equipped with the first annular welding ring and the second annular welds T-Ring, and between described cover plate and annular cavity, form airtight cavity, in described cavity, be provided with inertia rings, between described inertia rings and the formed gap of cavity, be filled with fluid silicone oil.
Adopted technique scheme, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, structural member adopts sheet metal part entirely, and between frame and cover plate, by being welded and fixed and forming sealed volume, overall structure has reduced the operation of manufacturing processing, comparatively easy, also be convenient to follow-up installing and using, saved a large amount of materials simultaneously, reduced the cost of manufacturing processing.
Accompanying drawing explanation
