Description
Technical field
The utility model relates to flexible member and manufactures and designs field, is specially a kind of spiral heavily stressed spring.
Background technology
Spring is a kind of machine components that utilize elasticity to carry out work, in order to control the motion of parts, relax and impact or vibrations, storage power, the size of ergometry etc., be widely used in machine, in instrument, at present a lot of occasions all need to use heavily stressed spring, and in order to improve the stress of spring, traditional design is all to adopt heavily stressed material to make spring, or simply strengthen the diameter of spring wire, all good balance costs of these two kinds of modes, the factors such as performance and used life, especially when in the face of high-frequency reciprocating motion, these problems are more serious, if can invent a kind of ability that can strengthen when needed spring load stress, and the novel spring structure that does not reduce spring whole service life in the time carrying out high frequency and low stress motion just can solve problems, we provide a kind of spiral heavily stressed spring for this reason.
Utility model content
The purpose of this utility model is to provide a kind of spiral heavily stressed spring, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of spiral heavily stressed spring, comprise bulky spring, the bottom of described bulky spring is provided with end gripper shoe, and the upper end of bulky spring is provided with middle gripper shoe, the inside of described bulky spring is provided with hairspring, and the lower end of hairspring and end gripper shoe welded and installed, the upper end of described hairspring is through middle gripper shoe, and the upper end of hairspring is provided with upper backup pad, the lower end of described upper backup pad is provided with support column, the lower end of described support column is through middle gripper shoe, and the lower end of support column is welded with the anti-decylization that is socketed in bulky spring outer wall, described bulky spring is made up of spring wire spiral, and the cross section of spring wire is the axis direction that the major axis in the cross section of ellipse and spring wire is positioned at bulky spring, the outer end of described spring wire is provided with bead layer and plastic-blasting layer successively.
Preferably, the bottom of described bulky spring is one-body molded bracing ring, and the upper end of gripper shoe, the described end is provided with spring groove, and bracing ring welded and installed is in spring groove.
Preferably, the two ends up and down of described middle gripper shoe are provided with vibration damping sheet, and vibration damping sheet and the bonding installation of middle gripper shoe.
Preferably, the lower end of described upper backup pad is at least welded with the support column of three equidistant arrays, and the outer end of support column is provided with polishing layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being combined to form new spring structure by two kinds of springs, make this spring structure in the heavily stressed impact of reply, can have good service life, and this spring structure has in the complicated field of force and has better performance performance in reply, especially there is the occasion of torsion in reply.
