Abstract
The utility model discloses a clutch device. The clutch device drives a cam to move through a driving rotating shaft; when the cam is in contact with rollers, the rollers move outwards to extrude the inner chamber of a driven plate; when the rollers are in contact with the inner chamber of the driven plate, the rollers are locked through the friction between the rollers and the inner chamber of the driven plate, or are embedded in grooves in the inner chamber of the driven plate to drive the driven plate to operate; damping devices are arranged between a positioning plate and two opposite planes of a fixed base plate; when the cam rotates in an opposite direction with a proper angle and stops, damping is generated between the positioning plate and the fixed base plate through the damping devices, so that the positioning plate cannot rotate along with the cam, and the positions of the rollers are not changed, which ensures that the rollers are in the curve circular arc area of the cam; when the rollers are in the curve circular arc area of the cam, the clearance between the inner chamber of the driven plate and the cam is larger than the external diameter of the rollers, the rollers are released, and the driven plate can rotate freely; and at this moment, hand-pulled dragging can be carried out, that is, the hand-operated function is achieved. The clutch device can be operated manually in the case that a system is closed-down or no switch is touched, and is applied to the field of clutches.

The specific embodiment
With reference to Fig. 1～Fig. 5; The utility model is a kind of arrangement of clutch; Comprise firm banking dish 1 and be provided with an inner chamber body and be installed on the clutch plate 2 of firm banking dish 1 outer ring that the center of running through firm banking dish 1 is provided with active rotating shaft 3, the end of active rotating shaft 3 is installed with cam 6; Firm banking dish 1 is provided with the positioning disk 4 of fitting with it; Positioning disk 4 is provided with roller slot 41, is provided with in the said roller slot 41 through cam 6 and stirs the roller 5 that in roller slot 41, slides, and is provided with damping unit between two opposite planar of positioning disk 4 and firm banking dish 1.
This arrangement of clutch drives cam 6 motions through active rotating shaft 3; Cam 6 touches roller 5 makes it push clutch plate 2 inner chambers laterally, and behind roller 5 contact clutch plates 2 inner chambers, the groove that perhaps embeds clutch plate 2 inner chambers through the friction self-locking with clutch plate 2 inner chambers drives clutch plate 2 runnings; This arrangement of clutch is provided with damping unit between two opposite planar of positioning disk 4 and firm banking dish 1; When stopping after the cam 6 counter-rotating proper angle, damping unit makes positioning disk 4 and 1 on firm banking dish produce damping and make positioning disk 4 can not rotate with cam 6, maintains the position of roller 5; Make roller 5 be in cam 6 curve circular arcs zone; The gap is greater than roller 5 external diameters between these position clutch plate 2 inner chambers and cam 6, and roller 5 is released, and clutch plate 2 can rotate freely; Can pull to drag has realized manual function this moment, and this arrangement of clutch is at system-down or do not touch all can be through manual operation under the situation of any switch.
Positioning disk 4 is when cam 6 reverses proper angle, to maintain the position of roller 5 for guaranteeing, makes roller 5 be in cam 6 curve circular arcs zone.
As the utility model preferred embodiment, damping unit is to be coated with the damping oil body between two opposite planar of being located at positioning disk 4 and firm banking dish 1 and/or to be arranged at positioning disk 4 opposite sides positioning disk 4 is pressed in the shell fragment on the firm banking dish 1.
The damping unit that is arranged at 1 on positioning disk 4 and firm banking dish can have multiple choices; Damping oil body and shell fragment are set to the utility model preferred embodiment; Certainly also can be provided with, guarantee the viscous effect of 1 pair of positioning disk 4 of firm banking dish through permanent magnet etc.
As the utility model preferred embodiment, the inner chamber of clutch plate 2 is smooth circular planes and/or is provided with to the recessed pit 7 of outer wall.
When the inner chamber of clutch plate 2 is smooth circular planes,, can provide roller 5 to drive the power of clutch plates 2 rotations through the planar friction self-locking between roller 5 and circular planes.
And when the inner chamber of clutch plate 2 is provided with to the recessed pit 7 of outer wall, can drives roller 5 through cam 6 and embed pits 7, thereby drive clutch plate 2 rotations, do not need self-locking this moment.
These two kinds of embodiments all are the enforceable embodiment of the utility model, also do not get rid of other similar with it conventional techniques means certainly also in protection scope of the present invention.
As the utility model preferred embodiment, the outer rim of cam 6 is two symmetrical curves, and the stage casing of one of which side is and the arc section plane of active rotating shaft 3 concentrics that the both sides on this arc section plane are the straight plane that two segment tilted directions are provided with.。
As the utility model preferred embodiment; Roller 5 is the cylindricality roller; Can be not carrying magnetic roller, roller 5 height vertically is greater than the level of roller slot 41 or clutch plate 2, cam 6 through stir state roller 5 roller slot 41 Outboard Sections along the axle center movement outside.
This arrangement of clutch can be applicable to have the occasion of program control system drive motors.Be particularly useful in the electrically driven curtain described below, concrete system comprises: drag dolly 10, hanging wheel 20, track 30, belt 40, belt pulley 50, clutch 60, motor 70.
The control system passes through this clutch 60 drive belt pulleys 50 rotations during 70 motions of control motor, and belt pulley 50 drives belt 40 motions, drags dolly 10 and is fixed on the belt 40, and meeting is moved with belt 40, thereby the drive casement carry out folding, realizes the curtain motor function.When running to desired location or when having a power failure, after the motor stall, send reverse signal in short-term, stop after making cam 6 counter-rotating proper angle through built-in energy storage device discharge control system.Roller 5 is in the curve circular arc zone on the cam 6.Because positioning disk 4 is mounted in the base outer ring, having damping unit again provides suitable resistance, can not follow cam 6 counter-rotatings, and damping force keeps the position of roller 5, and the gap is greater than roller 5 external diameters between these position clutch plate 2 inner chambers and cam 6.Roller 5 is released, and clutch plate 2 can rotate freely, and can pull and drag dolly and realized manual function this moment.
Positioning disk 4 is for guaranteeing that when motor reversed moment or driven pulley 2 active rotation, roller 5 was interval from the cam circular curve by band.It is useful that relative rotational resistance is arranged between positioning disk 4 and the firm banking 1.This can compress and increase friction through be coated with damping oil or reed at positioning disk 4 and 1 of firm banking, or realizes through modes such as permanent magnet resistances.
Certainly; The invention is not limited to above-mentioned embodiment; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
