Abstract
Silicon oil damper thrust bearing, including bearing body, bearing body are open annular, and the end face of bearing body is provided with multiple arcs boss, and arc boss is circumferentially uniformly arranged, so as to form convex-concave staircase structural model.The present invention：On the premise of considering not hindering silicone oil to flow freely and take into account the natural characteristic that temperature change during use is expanded with heat and contract with cold to its own, and the factor such as moulding process simplicity and design.
Description
Technical field
The present invention relates to silicon oil damper rank, especially a kind of silicon oil damper stepwise, the thrust bearing of opening.
Background technology
Thrust bearing is the important component of silicon oil damper.The major function of silicon oil damper is to reduce crankshaft vibration amplitude, ensures bent axle safety, and its operation principle is：The inertia ring in housing is suspended under the appropriate damping action of silicone oil, suitable relative motion is produced with bent axle, so as to reduce crankshaft torsional vibrations amplitude.This bearing is arranged among the movement clearance between inertia ring and housing, and main function is exactly support or stops the direct service life for producing rigid contact, extending shock absorber by the wear-resistant function of itself between inertia ring and housing.
The content of the invention
There is the problem of wearing no resistance and wearing inhomogeneities in the thrust bearing in existing silicon oil damper, the present invention proposes a kind of silicon oil damper thrust bearing.
In order to solve the above-mentioned technical problem, the technical scheme is that：Silicon oil damper thrust bearing, including bearing body, it is characterised in that：Bearing body is open annular, and the end face of bearing body is provided with multiple arcs boss, and arc boss is circumferentially uniformly arranged, so as to form convex-concave staircase structural model.
To the further restriction of above-mentioned technical proposal, the opening structure of the bearing body is：Overlap joint arm and lower overlap joint arm are mutually extended between the opening both ends of bearing body.Advantage：Coordinated by the mutual extension of upper overlap joint arm and lower overlap joint arm, the opening of bearing body is coordinated stabilization, avoid deforming.
To the further restriction of above-mentioned technical proposal, race diameter ＜ 1000mm, inner ring diameter ＞ 100mm, the thickness of bearing body are 3~10mm.Advantage：The restriction of size, optimal thrust effect can be ensured, it is ensured that the steady operating of inertia ring, while the product integral vibration damping function of its application is not influenceed, and can extends the product service life of its application.
To the further restriction of above-mentioned technical proposal, the material that the bearing body uses is plastics or nylon.Advantage：Material is easy to get, and can simplify manufacturing process, reduces production cost.
Beneficial effect：1. to prevent bearing body to be affected by temperature generation warpage, open type is designed to, ensures that its circumferentially extending shrinks freely；2. being not hinder the free-flowing of silicone oil and reduce caused rigid contact between inertia ring and adjacent housings, cover plate, the end face of bearing body is designed to convex-concave staircase structural model, also solves the problem of wearing inhomogeneities；3. the structure of the present invention is simple, production cost is low, service life length.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, silicon oil damper thrust bearing, including bearing body 1, bearing body 1 are open annular, and the end face of bearing body 1 is provided with multiple arcs boss 2, and arc boss 2 is circumferentially uniformly arranged, so as to form convex-concave staircase structural model；The hatch frame of the bearing body 1 is：Convex platform 3 and lower convex platform 4 are mutually extended between the left and right both ends of bearing body 1, the shape of convex platform 3 is to be and bearing body inner ring curvature radius identical arc shape with the shape of bearing body outer shroud curvature radius identical arc shape, lower convex platform 4.
The race diameter of the bearing body is 150~800mm, inner ring diameter is 100~600mm, thickness is 3~5mm.The bearing body mainly using injection but is not limited to be molded by the way of injection, is made up of plastics or nylon material.
The use state of the present invention：As shown in Figure 4 and Figure 5, bearing body is arranged in the groove 6 in the both ends of the surface of inertia ring 5, and the convex-concave staircase structural model on bearing body is used to stop caused rigid contact between inertia ring and adjacent housings 7, cover plate 8；Silicone oil flows from the recess on bearing body convex-concave staircase structural model, does not hinder the free-flowing of silicone oil.In motion process, bearing body is open annular, prevent its occur axial warpage the problem of.
Finally it should be noted that：Example discussed above is only the preferred embodiments of the present invention, not limits technical scheme described in the invention.Therefore, for the person of ordinary skill of the art, on the premise of its general principles are not departed from, if the variations and modifications of stem structure can also be carried out, this also should be regarded as protection scope of the present invention.
