Fig. 2 is structural representation of the present invention.
Embodiment
Below the present invention is described in further details.See Fig. 2, a kind of leaf spring structure for linear electric motor, comprises one-level leaf spring 1, locking nut 4, armature 5, stop collar 6 and housing 7, in housing 7, there is a left sector hole footpath to be greater than the step hole in right sector hole footpath, the right-hand member of stop collar 6 is positioned at the left sector hole of housing 7, armature 5 is with externally threaded circular shaft, armature 5 is positioned at the center hole of stop collar 6 and housing 7, one-level leaf spring 1 is a circular plate with screwed hole of centre, an annular boss 1a is had around one-level leaf spring 1 screwed hole of centre, one-level leaf spring 1 is screwed on the outside thread of armature 5, the circumference of one-level leaf spring 1 is positioned at the left sector hole of housing 7, fit in the left surface of one-level leaf spring 1 circumference and the right side of stop collar 6, locking nut 4 is screwed on the outside thread of armature 5, it is characterized in that: have a back-up ring 2 and a secondary leaf spring 3, the annulus of back-up ring 2 to be cross sections be rectangle, the axial length of back-up ring 2 equals the axial height of annular boss 1a, the external diameter of back-up ring 2 coordinates with the bore clearance of the left sector hole of housing 7, the center hole of secondary leaf spring 3 is unthreaded hole, the aperture of this unthreaded hole coordinates with the externally threaded crest clearance of armature 5, all the other physical dimensions of secondary leaf spring 3 are identical with one-level leaf spring 1, secondary leaf spring 3 is enclosed within the outside thread of armature 5, back-up ring 2 is between one-level leaf spring 1 and secondary leaf spring 3, locking nut 4 is positioned at the right of secondary leaf spring 3, one-level leaf spring 1 and secondary leaf spring 3 are locked, the right surface of secondary leaf spring 3 circumference and the step end face of housing 7 endoporus are fitted.
Working principle of the present invention is: the present invention, by connect in the axial direction a secondary leaf spring and back-up ring, realizes the requirement that linear electric motor increase elastic force; The center hole of secondary leaf spring is taked to coordinate with the crest clearance of armature simultaneously, through verification experimental verification, if take the center hole of secondary leaf spring to coordinate with the outer-diameter threads of armature, spring force can not realize linear superposition and meet the requirements of double output, and take the center hole of secondary leaf spring to coordinate with the crest clearance of armature, this Spielpassung can eliminate the Planar Mechanisms that screw-thread fit is brought, and avoids the predeformation of leaf spring, realizes the linear superposition of spring force.
The invention solves by restrictions such as spring material, installing space, weight demands, the elastic force of one-level leaf spring is limited, can not meet the problem of linear electric motor to the requirement of increase elastic force.By (or multiple) secondary leaf spring and the back-up ring of connecting in the axial direction, realize the double or many times of outputs of spring force, be a kind of difficulty of processing little, be easy to install, the reliable scheme of the invention of structure.
