Abstract
The invention relates to a wind-driven generating equipment component and a manufacturing method, in particular to a low-strain low-stress elastic support of a wind driven generator bearing bush type gearbox and a forming method of the elastic support. The elastic support comprises at least two coaxial semi-cylindrical bearing bush sheet steel layers; multiple rubber elastomers are arranged between every two adjacent bearing bush sheet steel layers by means of vulcanization and solidification; the rubber elastomers are partitioned into multiple columns through axial partitioning slots and partitioned into multiple rows via circumferential partitioning slots in the circumferential direction. The axial longer elastomers of the elastic support of the gearbox are partitioned into two or more small elastomers through a special die, so that deformation and strain of the elastomers are lowered, and endurance life of the elastomers can be prolonged. By the forming method, due to axial loose cores and peripheral loose cores which are arranged, the elastomers longitudinally and transversely partitioned can be formed on the elastic support smoothly, and the manufacturing process is simple and convenient.
Description
Technical field
The present invention relates to a kind of wind power plant parts and manufacture method, specifically a kind of wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress and forming method thereof.
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 by this invention is, provides a kind of and can improve rubber elastomer strain stress situation, long service life, the wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress of good damping result and forming method thereof.
The wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress of the present invention 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 manufacture method of the wind-driven generator bearing shell formula gear case elastic support part of low strain dynamic stress of the present invention is: inject mould at rubber and coaxially load multilayer semicylindrical bearing shell sheet steel layer; Between adjacent two layers bearing shell sheet steel layer, load rectilinear axial core-pulling vertically, the circumference circumferentially loading circular arc between axial core-pulling both sides to bearing shell sheet steel layer edge is loosed core; Then inject mould by rubber and inject rubber and sulfuration consolidation to the cavity between adjacent two layers bearing shell sheet steel layer; Circumferentially extract each circumference after shaping out to loose core form circumferential separating groove from product both sides, then extract axial core-pulling out from the axial one or both ends of product and form axial separating groove.
In said method, described axial core-pulling can axially be divided into two sections, is connected to rubber and injects on the upper die and lower die of mould.When upper and lower mould can be utilized like this to remove, axial core-pulling is extracted out.
The axially longer elastomer of gear case elastic support part is separated into the mini-bomb gonosome of 2 pieces or more by the present invention by special mould, reduce elastomeric deformation and strain, can improve the elastomeric endurance life-span.Forming method of the present invention is by arranging axial core-pulling and circumference is loosed core, and the elastomer making the said goods can form polylith smoothly to separate in length and breadth, manufacture process is simple and convenient.
