Abstract
The utility model relates to a kind of wind power plant parts, specifically a kind of wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress.The wind-driven generator bearing shell formula gear case elastic support part of this low strain dynamic stress includes the semicylindrical bearing shell sheet steel layer of at least two-layer coaxial setting; Polylith rubber elastomer is consolidated with by sulfuration between adjacent two layers bearing shell sheet steel layer; Described polylith rubber elastomer is divided into multiple row by axial separating groove, and is divided into multirow by the circumferential separating groove of circumferencial direction.The axially longer elastomer of gear case elastic support part is separated into the mini-bomb gonosome of 2 pieces or more by the utility model by special mould, reduce elastomeric deformation and strain, can improve the elastomeric endurance life-span.
Description
Technical field
The utility model relates to a kind of wind power plant parts, specifically a kind of wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress.
Background technique
Wind-driven generator bearing shell formula gear case elastic support part is used to the parts gear-box of wind-driven generator being carried out to vibration reduction support, its structure generally includes the semicylindrical bearing shell sheet steel layer of at least two-layer coaxial setting, by sulfuration consolidation rubber elastomer between adjacent two layers bearing shell sheet steel layer, this supporting element paired mounting carries out clamp standoff to gearbox shaft in gear-box supporting base.In this structure, rubber elastomer is axially usually as a whole.Axially increase length in elastomer, namely increase the bearing area of rubber, can improve the load-carrying properties of product, rigidity can be greatly improved.But axially go up length long after, in the middle part of it, the deformation of rubber and stress also increase.Find that the stress in the middle part of rubber is maximum, and rubber deformation is maximum at axially installation direction by test, under the effect of cycle facigue load, easily occur that rubber shears wearing and tearing powdered phenomenon.If change not in time, then aggravation of wearing and tearing, product rigidity is constantly lost, and finally make gear-box deformation aggravate, vibration acceleration exceeds standard.Therefore, in existing structure, the high-mechanic performance of product and the reliability of product become the contradiction being difficult to for a pair take into account.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress that can improve rubber elastomer strain stress situation, long service life, good damping result.
The wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress of the present utility model includes the semicylindrical bearing shell sheet steel layer of at least two-layer coaxial setting; Polylith rubber elastomer is consolidated with by sulfuration between adjacent two layers bearing shell sheet steel layer; Described polylith rubber elastomer is divided into multiple row by axial separating groove, and is divided into multirow by the circumferential separating groove of circumferencial direction.
Described bearing shell sheet steel layer is provided with three layers, and corresponding rubber elastomer is provided with two-layer.
The axially longer elastomer of gear case elastic support part is separated into the mini-bomb gonosome of 2 pieces or more by the utility model by special mould, reduce elastomeric deformation and strain, can improve the elastomeric endurance life-span.
