Abstract
The invention discloses a kind of adjustable spiral spring shell device with changeable spring coefficient. The spring coefficient is the loading readed for unit deformation. The said device consists of male shell body, female shell body and rotary body. One end of the spiral spring is fixed on a fixed seat located at the center of bottom of female shell body; the other end of the spiral spring is placed on inside of the male shell body. Multiple blocking bodies in outside diameter and inside diameter of the rotary body is contacted with the plain wire of spiral spring. Turning the rotary body changes effective number of turns of spiral spring compressed or pulled so as to change the spring coefficient, in order to adapt to various needs of different machines.
Description
The present invention relates to a kind of shell body device adjustable to the helical spring coefficient.
Common helical spring spring constant its specification when manufacturing is just definite, and drawing tension or the compressive force required because of various machines are not quite similar, so different helical spring specifications is arranged; Under same-handed spring specification and unit deformation condition, when the helical spring number of active coils is few more, its spring constant is big more, required drawing tension and compressive force are big more, when the helical spring number of active coils is many more, then spring constant is more little, and required drawing tension and compressive force are more little; Common helical spring specification is according to the design of the needs of machinery equipment, and the size of modulation spring constant arbitrarily, has reduced the elasticity of its use.
The purpose of this invention is to provide a kind of regulatable casing of spiral spring, make required that helical spring can be with the machinery equipment of using, and the helical spring spring constant of modulation, to reach the elasticity when using; Its principle is to change helical spring effective number of coils of power or drawing tension by compression, just can reach the purpose of the helical spring spring constant of change, and making it has the different drawing tensions or the ability of compressive force of bearing in the unit deformation amount.
For reaching above-mentioned purpose, the present invention by the following technical solutions:
Public housing, parent shell and solid of rotation have been the present invention includes, parent shell bottom centre wherein is provided with fixed base, the male and female housing is formed a housing, helical spring one end is fixed in fixed base, and the other end is placed on public enclosure interior, and solid of rotation is a hollow article, between the male and female housing, public housing external diameter is slightly less than the solid of rotation internal diameter, and the solid of rotation external diameter is slightly less than the parent shell internal diameter; Or public housing internal diameter is slightly larger than the solid of rotation external diameter, and the solid of rotation internal diameter is slightly larger than the parent shell external diameter, and this solid of rotation internal diameter appropriate location is provided with several resistance bodies and contacts with helical spring plain line, for the coefficient magnitude of adjusting helical spring spring.
The present invention is when concrete the use, rotate solid of rotation and just can change helical spring effective spring constant of power or drawing tension by compression, reached the purpose of adjusting helical spring spring constant, can use helical spring spring constant and change arbitrarily with institute's requirement of use machinery equipment.
