Description
Technical field
The present invention relates to a kind of magnetic clutch, particularly relate to a kind of electromagnetism torsional spring clutch that utilizes multi-disc clutch component to handle.
Background technique
The applicant once also once applied for " a kind of torsional spring type magnetic clutch " (not yet open at present) on March 16th, 2014, its torsion spring is positioned at outside adhesive dish sleeve, follower sleeve, under free state, its internal diameter is greater than the external diameter of follower sleeve, its first pin stretches in adhesive dish breach, and its second pin stretches in follower breach.But still there is certain defect in this structure: due in the process of clutch, thereby the left and right displacement of adhesive dish drives torsion spring hold tightly and unclamp driving wheel, in the time holding tightly, the moment of torsion of driving wheel is mainly that pin of torsion spring by holding tightly transmits another pin by moment of torsion and finally passes to follower, therefore two of torsion spring pins need to bear very large moment of torsion, to the fatigue strength of its material, rigidity, size has proposed higher requirement, and hold tightly and unclamp in the process of driving wheel at torsion spring, torsion spring with respect to driving wheel not only its circumferential internal diameter change, its left and right also can play, form the shear action to driving wheel, cause heterogeneity wearing and tearing between the two, finally causing torsion spring to be held tightly with release function lost efficacy. there is locking phenomenon.End face and the clutch frequently of electromagnet assembly end face of the dish of adhesive simultaneously, in clutch process, between the end face of adhesive dish and electromagnet assembly end face, impact force is larger, and wearing and tearing can be more serious, thereby make the stability deficiency of total.
Summary of the invention
