Abstract

Present invention relates to a ratchet arrangement, in particular an automatically on-off reversible ratchet arrangement. It contains housing, jaw clutch installed in housing, disengaging spring fit between jaw clutch driving disc and driven disk, said driving disc sleeved on spiral splined spindle through internal spline, spiral splined spindle top being a polished rod, driven disk rotatablely sleeved on spiral splined spindle top, driven disk fixed joint driving shaft, driving shaft fit on shell cover, spiral splined spindle terminal fixed joint friction disk, said wearing plate installed with platen, platen spring installed between platen and rear endplate. Said device not only can complete common ratchet arrangement action but also self-return after completing handle action, driving disc driven disk automatically separation, driven disk capable of positive and reversal free rotation to satisfy special requirement.

Description

technical field [0001] The invention relates to a ratchet device, in particular to an automatic clutch reversible ratchet device. Background technique [0002] In the manipulation control mechanism of mechanical equipment, ratchet device is often used. In the high-power operating device, the ratchet device is required not only to have the ability of one-way driving, but also to have the function of automatic separation, so as to avoid the operation handle from reversing and hurting people when the equipment is running suddenly. Although existing various ratchet devices have the function of one-way driving, their moving parts are often engaged, which cannot meet the above-mentioned requirements. For example, my other patent application: "Manual opening device of permanent magnet switch operating mechanism" (application number CN200510042050.7), discloses a device that can make the output shaft move axially and lock automatically. The device drives the output shaft to move a...
