Abstract
The utility model discloses a clutch. The fixed sleeve and the output shaft of the clutch are at the concentric circle position, two inclined planes are respectively arranged at the two sides of the external wall of the output shaft, round stop pins are respectively arranged between the inclined planes and the internal wall of the fixed sleeve, the diameters of the round stop pins are larger than the minimum distance between the internal wall of the fixed sleeve and the inclined planes of the output shaft, and smaller than the maximum distance between the internal wall of the fixed sleeve and the inclined planes of the output shaft; each spring is connected with two round stop pins, a hand-operated mechanism is positioned between the fixed sleeve and the output shaft and can move between the two groups of round stop pins. By adopting the technical proposal of the clutch, in an electric actuating mechanism, the mechanism can be automatically switched without a hand, and manual operation can be realized, thus the manual operation is guaranteed to be safe.
Description
Technical field
The utility model relates to a kind of clutch.
Background technique
Electric actuator in actual use, Chang Yinchu debugs reasons such as examination, overhaul of the equipments or instrument operation troubles must the manually-operable electric actuator, the parts so manual operating device is absolutely necessary in electric actuator.
For preventing that motor send electricity suddenly manually the time, the hand rotation operator that injures has the preferential hand mechanism for automatically switching of motor in traditional manual operating device.This mechanism is complicated, processing and assembling also difficulty.Do not use differential gear instead if do not use switching mechanism, then can overcome the electronic and manual contradiction of interlock mutually effectively, but handwheel must self-locking could not guarantee electronic proper functioning when manually not using.In order in electric actuator, to use differential gear train, just must the transmission of a kind of forward energy of design, the oppositely parts of energy self-locking.
The model utility content
The purpose of this utility model is to propose a kind of clutch, can need not the hand mechanism for automatically switching in electric actuator, gets final product manually-operable, has guaranteed manually operated safety.
For reaching this purpose, the utility model by the following technical solutions:
A kind of clutch, comprise fixed cover 1, output shaft 2, man-operated mechanism 3, two springs 4,4 braking round pins 5, described fixed cover and described output shaft are in the concentric circle position, described output shaft outer wall both sides respectively are provided with 2 inclined-planes, described braking round pin lays respectively between described inclined-plane and the described fixed cover inwall, described braking round pin diameter is greater than the minimum range between described fixed cover inwall and the described output shaft chamfered portion, less than the ultimate range between described fixed cover inwall and the described output shaft inclined-plane, every described spring connects 2 described braking round pins, described man-operated mechanism is between described fixed cover and described output shaft, described man-operated mechanism can move between two groups of braking round pins, is used to push described braking round pin.
Adopted the technical solution of the utility model, the clutch configuration compactness, part manufacturing, assembly technology are simple, easy operating; Be used for electric actuator, need not the hand mechanism for automatically switching, manually-operable is safe and reliable, has overcome the shortcoming inconsistent with electric operating; The actuation mechanism of also can working poor is used for the axle class of the unidirectional transmission of various palpuses.
Description of drawings
Fig. 1 is the cross section structure schematic representation of clutch in the utility model embodiment.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the cross section structure schematic representation of clutch in the utility model embodiment.As shown in Figure 1, clutch comprises fixed cover 1, output shaft 2, man-operated mechanism 3, two 4,4 brakings of spring round pins 5.
Fixed cover and output shaft are in the concentric circle position, output shaft outer wall both sides respectively are provided with 2 inclined-planes, the braking round pin lays respectively between inclined-plane and the fixed cover inwall, braking round pin diameter is greater than the minimum range between fixed cover inwall and the output shaft chamfered portion, less than the ultimate range between fixed cover inwall and the inclined-plane, every spring connects 2 braking round pins, and man-operated mechanism is between fixed cover and output shaft, and man-operated mechanism can move between two groups of braking round pins.
When man-operated mechanism is motionless, if output shaft relative fixed cover rotates to any direction, the inclined-plane on the output shaft will produce pressure to the braking round pin, produce interaction force between braking round pin and the fixed cover inwall, and the braking round pin will block output shaft and can not rotate.
When rotation manual mechanism, man-operated mechanism will push the braking round pin and move, and make the braking round pin break away from braking state, brake round pin simultaneously the inclined-plane on the output shaft is produced Driving force, thereby make output shaft to rotate along the direction that man-operated mechanism rotates.
This embodiment is to have adopted two groups of braking round pins and man-operated mechanism, can certainly adopt to be no less than three groups of braking round pins and man-operated mechanism.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
