Abstract
The invention relates to a large-stiffness plane spring, comprising a thin-wall ring body, wherein upper and lower surfaces of the thin-wall ring body respectively are provided with convex radial cords which are arranged uniformly; radial cords on a surface and radial cords on the other one surface are misplaced with each other; an elastic deformation area is formed between adjacent radial cords of upper and lower surfaces; the ring body is made of spring steel; upper and lower surfaces of the ring body are provided with 6-8 convex radial cords which are arranged uniformly and which are processed by the milling or turning technology. The large-stiffness plane spring provided by the invention is manufactured conveniently, and also is deformed less by mainly utilizing inherent elastic deformation properties of materials, so that the large-stiffness plane spring has the advantages of simple structure, small deformation, easy property for manufacturing, large generated pressure, uniform force on a plane, and convenience for mounting.
Description
Technical field
What the present invention relates to is a kind of occasion that is applied to need high precompression, like the plane spring of the big rigidity of large-scale safety clutch, large press.
Background technique
Existing spring mainly contains: spiral steel wire spring, belleville spring, wavy spring; Because spring is all less than normal in rigidity now; Distortion will be big when needing to produce very big power, and axial dimension is just big, and large-sized belleville spring and wavy spring manufacture difficulty are big; The processing request frock is many, and amount of deformation and apply the power non-linear relation.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing technology exists, and provide a kind of simple in structure, be easy to make, be out of shape little, the plane spring of the stressed big rigidity even, easy for installation in the big and plane of generation pressure.
The objective of the invention is to accomplish through following technological scheme; It comprises a thin wall circular body; Be shaped on radially raised line of the spirogyrate that is uniformly distributed with respectively at the upper and lower surfaces of this thin wall circular body; And the radially raised line mutual dislocation on the radially raised line on a surface and another surface is arranged, and between the adjacent radial raised line on said two surfaces up and down, is formed a resiliently deformable zone.
Cirque body according to the invention selects for use spring steel to process, and two surfaces up and down wherein adopt car or miller skill to be processed with radially raised line of 6-8 spirogyrates that are uniformly distributed with respectively.
The present invention mainly is a characteristic of utilizing the intrinsic resiliently deformable of material, makes to make simply, and it is little to satisfy distortion again, has simple in structurely, is easy to make, be out of shape little, the stressed characteristics such as even, easy for installation in the big and plane of generation pressure.
Description of drawings
Fig. 1 is a Facad structure schematic representation of the present invention.
Fig. 2 is a side structure schematic representation of the present invention.
Embodiment
To combine below accompanying drawing to the present invention make detailed introduction: Fig. 1, shown in 2; The present invention includes a thin wall circular body 1; Be shaped on radially raised line 2 of the spirogyrate that is uniformly distributed with respectively at the upper and lower surfaces of this thin wall circular body 1; And the radially raised line 2 on a surface is arranged with radially raised line 2 mutual dislocation on another surface, and between the adjacent radial raised line 2 on said two surfaces up and down, is formed a resiliently deformable zone 3.
Cirque body 1 according to the invention selects for use spring steel to process, and two surfaces up and down wherein adopt car or miller skill to be processed with radially raised line 2 of 6-8 spirogyrates that are uniformly distributed with respectively.
Embodiment:
Plane spring of the present invention is after passing through to analyze belleville spring, wavy spring structure; Select for use spring steel (like 50CrV, 38CrSi etc.) to make material,, design the two-sided boss of 6 five equilibriums, 8 five equilibriums according to diameter; Can adopt car, miller skill to process boss; Carry out effective heat treatment process, utilize the Young's modulus of material, be made into plane spring.
The present invention is through the Pressure testing of plane spring; After eliminating form and position tolerance, its rigidity is linear relationship basically, can find out from the Pressure testing test curve; Plane spring is after distortion 0.3mm; Distortion just becomes linear relationship basically with the relation of exerting pressure, and the control (adjustment) through to amount of deformation can obtain our needed power.
Claims (2)
1. the plane spring of a big rigidity; It comprises a thin wall circular body; The upper and lower surfaces that it is characterized in that said thin wall circular body is shaped on radially raised line of the spirogyrate that is uniformly distributed with respectively; And the radially raised line mutual dislocation on the radially raised line on a surface and another surface is arranged, and between the adjacent radial raised line on said two surfaces up and down, is formed a resiliently deformable zone.
2. the plane spring of big rigidity according to claim 1 is characterized in that said cirque body selects for use spring steel to process, and two surfaces up and down wherein adopt car or miller skill to be processed with radially raised line of 6-8 spirogyrates that are uniformly distributed with respectively.
