Abstract
The utility model relates to a multiple ratchet overdrive clutch reset by magnetic force spring used for mechanical engineering, which is composed of a ratchet wheel 1, ratchets 2, an upper magnet 3, a lower magnet 4 and a ratchet disk 5, wherein, the ratchet wheel 1 and the ratchets 2 are arranged on the ratchet disk 5; the upper magnet 3 and the lower magnet 4 are arranged on the end part of the ratchets 2; the same poles of the upper magnet 3 and the lower magnet 4 corresponding all ratchets 2 on the ratchet disk are opposite; the ratchet return spring can work through the magnetic force of homosexual homogeneity repulsion permanent magnets; namely, the return spring is two repellent permanent magnets for replacing the return spring of the ratchets; so as the permanent magnets can not lose magnetism, the magnetic spring can not fail; thereby, the effective of a whole ratchet wheel overdrive clutch can be ensured; the goals of firmness, reliability and service life extension can be achieved.
Description
The utility model relates to a kind of many ratchets free wheel device that resets with magnetic spring in the mechanical engineering.
Ratchet type overrunning clutch has been well-known, influence the intensity of the non-click of most critical factor in its working life, but the metal fatigue of its pawl restoring spring makes spring failure, cause whole ratchet free wheel device to lose efficacy, this is that ratchet type overrunning clutch is failed the basic reason of extensive use in more powerful mechanical engineering.The working life of common spring, only 1,000 ten thousand compressions resetted, and surmounted the very fast inefficacy of common spring under the frequency higher.
The purpose of this utility model is to provide a kind of a kind of many ratchets free wheel device that resets with magnetic spring of avoiding making owing to the metal fatigue of common spring whole ratchet free wheel device inefficacy.
The utility model is achieved in that by ratchet 1, ratchet 2, upward magnet 3, lower magnet 4, pawl disk 5 are formed, and ratchet 1, ratchet 2 are arranged on the ratchet 5, and there are last magnet 3, lower magnet 4 in the end of ratchet 2.
Last corresponding magnet 3, lower magnet 4 magnet homopolarities on the ratchet 2 are relative.
Advantage of the present utility model is that pawl restoring spring uses be by the same sex repel each other permanent magnet magnetic force and work, be that Returnning spring is two blocks of permanent magnets that repel each other, utilize principle of same-sex repulsion, the Returnning spring that replaces ratchet, as long as permanent magnet is loss of excitation not, this magnetic spring just can not lose efficacy, thereby guarantees the effective of whole ratchet free wheel device, really reaches purpose sturdy, reliable, that increase the service life.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is made up of ratchet 1, ratchet 2, last magnet 3, lower magnet 4, pawl disk 5, and ratchet 1, ratchet 2 are arranged on the ratchet 5, and there are last magnet 3, lower magnet 4 in the end of ratchet 2.
Claims (2)
1. many ratchets free wheel device that resets with magnetic spring, form by ratchet (1), ratchet (2), last magnet (3), lower magnet (4), pawl disk (5), ratchet (1), ratchet (2) are arranged on the ratchet (5), it is characterized in that: there are last magnet (3), lower magnet (4) in the end of ratchet (2).
2. a kind of many ratchets free wheel device that resets with magnetic spring according to claim 1 is characterized in that: it is relative that ratchet (2) is gone up corresponding last magnet (3), lower magnet (4) magnet homopolarity.
