Abstract
The utility model relates to a fan-shaped helical compression spring. The end part of the Fan-shaped helical compression spring is in a tight ground-flush type and takes the shape of a fan, and the radius centers of the big circle and the small circle of the fan are positioned on intersecting lines of extending faces of two end faces. The fan-shaped helical compression spring is specially used for absorbing tangential force from a circumferential direction. As the end faces of the spring are vertical to the tangential force direction, the overall shock absorption ability of the spring is optimal, the damping effect is best, and the defects of weak shock absorption ability and poor damping effect of a cylindrical helical compression spring due to unilateral absorption force are overcome. Thus, the fan-shaped helical compression spring has the advantages of reasonable design, simple structure, strong shock absorption ability, good damping effect, high fatigue resistance and long service life.
Description
Technical field
The utility model relates to the shape and structure of a kind of spiral compression spring, particularly a kind of spiral compression spring, belongs to elastic part design and manufacturing technology field.
Background technique
The kind of spring is a lot, common are in the machinery at present: helical spring, belleville spring, annular spring, cup spring, leaf spring etc., wherein helical spring is made easy advantage owing to having, and is widely used.Helical spring is divided into again extension spring, Compress Spring, torsion spring etc. by its external load function power mode difference.It is cylindrical spiral that existing Compress Spring mostly is greatly, and normal the employing also tightly polishes the type end construction in the important place of varying load, and makes end face vertical with the axis of spring.This spring generally is used in the shock-absorbing occasion, because the axis of spring is consistent with force direction, so the damping capaicty of spring is maximum.But, at some special occasions, such as when need that spring absorbs in the tangential force of circumferencial direction the time, the spring of this structural type often can not satisfy usage requirement, even also be monolateral stressed when using reluctantly, the damping capaicty of spring integral body can not be fully played, and long-time use also fatigue crack can occur, even fracture.
Summary of the invention
The purpose of this utility model is to provide a kind of sector shaped helical Compress Spring, solve cylindrical helical compression spring absorb come when the tangential force of circumferencial direction, the damping capaicty that shows is poor, resist that intensity is low, working life short problem.
To achieve these goals, the utility model Bian gets following technological scheme and implements: a kind of sector shaped helical Compress Spring, its end for and tightly polish type, shape and structure is fan-shaped, and fan-shaped great circle and roundlet center of radius are positioned on the intersection line of both ends of the surface extended surface.
The utility model be specifically designed to absorb in the tangential force of circumferencial direction, because end face and the tangential force perpendicular direction of spring, therefore the whole damping capaicty of spring is best, damping effect is best, has changed cylindrical helical compression spring because the shock-absorbing that monolateral suction brings is weak, the poor defective of damping.Therefore the utlity model has reasonable in design, simple in structure, damping capaicty strong, good damping effect, fatigue resistance is high, the advantage of long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In Fig. 1: the large circle radius of intersection line, R of 1 spring body, O two ends extended surface, the little circle radius of r.
Embodiment
As shown in Figure 1, the utility model is end and tightly polish the fan-shaped Compress Spring of type, and the shape and structure of spring body 1 is fan-shaped, and fan-shaped great circle radius R and roundlet radius r total is centered close on the intersection line O of spring body 1 two ends extended surface.
The utility model is used for vibration damper between motor and the torque-converters, uniform a plurality of spring bodies 1 on the setting circumference of vibration damper, the tangential inertial force of torque-converters acts on the end face of spring body 1 along the normal orientation of spring body 1 end face when the tangential forces of engine output torque or braking, the ability that makes spring body 1 integral body resist external force is not fully exerted, and the cushioning ability of vibration damper also reaches the best.
Claims (1)
1. sector shaped helical Compress Spring, its end for and tightly polish type, it is characterized in that: the structure shape of described spring is fan-shaped, and fan-shaped great circle and roundlet center of radius are positioned on the intersection line of both ends of the surface extended surface.
