Abstract
The invention discloses an electric clutch, which comprises a power input shaft and a power output shaft in the same axis, wherein a clutch device is arranged between the two shafts; the clutch device comprises a clutch block I connected to the power input shaft and a clutch block II movably sleeved on the power output shaft through a sliding key; the two clutch blocks are magnetizers, the opposite faces of the two clutch blocks are clutch contact faces, a return spring is arranged between the two clutch blocks, and coaxial coils are arranged on the peripheries of the two clutch blocks; when being electrified, the coils generate magnetism; and electric switches of the coils are synchronous with a power supply switch of the power input shaft. The power output shaft is a non-magnetizer and is in sliding fit with the clutch block II through a six-edge sliding key, and the shaft end of the clutch block II passes through the clutch block I and is extended to a shaft hole of the power input shaft and in sliding fit with the power input shaft. The clutch contact faces are corresponding umbrella-shaped tooth faces. The electric clutch has the advantages that: because the clutch switch is synchronous with the electric force source switch, normal transmission of an electric force can be realized, reverse transmission of mechanical torsion transmitted to a motor in a power-off state is blocked, and the effects of protecting the motor and decelerating a gear are achieved.
Description
Technical field
The present invention relates to mechanical drive clutch, be specially a kind of electric clutch.
Background technique
In many mechanical transmission mechanisms, general power source is a motor, and most motors run up, so need to slow down through turbine or gear train, just arrival is done manual work terminal at last.Need auto-manual for some occasion; Like the automatic flip of the WC pans of top grade system, micro motor can pass through mechanical reduction and drives toilet lid and start or fall under the automatic control state, if but start manually or when falling toilet lid; Will produce reverse transmission; The rotor of drive micromachine is high speed rotating passively, and at this moment motor will become generator, and the electric current of its generation might destroy control circuit.Undue force also may destroy driving gear.For the power transmission occasions of this hand from two controls, an engaging and disengaging gear is preferably arranged, make can not drive mechanical drive gear and motor rotation when manual, but do not have this device at present.
Summary of the invention
The objective of the invention is to overcome the defective of existing technology; A kind of electric clutch is provided; Smoothly transmission of power is held to acting through deceleration energy when making electric-motor-driving; And the machine power of acting end is unlikely to the reverse motor side that is transferred to through the clutch disconnection under the on-electric state, to reach the purpose of protection motor and driving gear set.
The technological scheme that the present invention taked is: a kind of electric clutch; Comprise the power input shaft and the pto that are in same axle center, engaging and disengaging gear is arranged between the diaxon, described engaging and disengaging gear comprises the clutch block one that is connected the power input shaft end and cooperates through feather key and is actively set on the clutch block two on the pto; Two clutch blocks are magnet case; The face that two clutch blocks are relative is the clutch surface of contact, between two clutch blocks return spring is arranged, and the periphery of two clutch blocks is the coil of concentric; Produce magnetic force during this coil electricity, the power switch of coil electric switch and power input shaft is synchronous.
Said pto is a non-magnetizer; The part surface that itself and clutch block two are slidingly matched is six rib feather keys; The axle center hole of clutch block two is corresponding six rib holes, and the axis hole that clutch block two axle heads pass clutch block one extends in the axis hole of power input shaft end, and is slidingly matched with it.This is slidingly matched, and is equivalent to the axle head sliding bearing of pto.
More specifically, said clutch block opposing contact clutch surface can be made into the corresponding umbrella flank of tooth, also can adopt the friction plate mode.
During work, when power switch is closed.Power input shaft running under electric power drives; Clutch switch is closed simultaneously; Coil produces stronger magnetic field, thereby makes two magnet case clutch blocks attract each other, and clutch block two can slide along pto (sliding key shaft); Tightly inhale together until two clutch blocks, thereby the rotation torsion of clutch block one is passed to clutch block two and pto; When the disconnection of power input shaft power supply, the clutch power supply also can break off simultaneously, the deactivation coil demagnetizing force; Under the effect of return spring, clutch block two leaves clutch block one, at this moment; If pto rotates under the manual force effect, the reverse transmission of power just can not take place under the effect of clutch.
Beneficial effect of the present invention: because this electronic Isolating Switch and electrodynamic source switch are synchronous; Can realize that electric power is to the proper Chang Chuandong of acting; And blocking-up mechanical torsion under non-power status is held to the reverse transmission of motor side by acting, can play the effect of protection motor and reduction gear.
