Abstract
The utility model discloses an automatic/manual switching device of an electric actuating mechanism, wherein a duplex gear, a gear, an overrunning clutch and a hand wheel component are sleeved in sequence on an output shaft; a planetary gear frame is connected with the output shaft through a spline, the planetary gears on a planetary gear frame are engaged with the duplex gear and the gear; the big gear wheel of the duplex gear is engaged with a gear shaft; a limit-torque machine is arranged on the side of the overrunning clutch, and a convex claw is arranged between the overrunning clutch anda driving plate connected with the hand wheel component. The utility model has the benefits that because the two-way overrunning clutch is connected to the actuating mechanism, when the actuating mechanism is operated electrically, the roller in a clutch clamps an inner ring and an outer ring on the outer side of a wedge-shaped groove, when the mechanism is operated manually the convex claw drives the roller to loosen the inner and outer rings, so as to rotate in the same direction, and the ranges of the speed and the torque of the actuating mechanism become wider; the manual operation requires no human-performing operation, which improves the working efficiency of the on-site technicians.
Description
Technical field
The utility model relates to a kind of electric actuator; Particularly relate in a kind of electric actuator automatically and the COMM communication of handwheel rotation.
Background technique
Existing electric actuator majority does not have clutch, has the part electric actuator to be provided with clutch yet, because clutch is installed, solved electric actuator when electronic, handwheel is not in the problem of together rotating, but actuator still needs manual operation manually with electronic the switching time.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, provide a kind of electric actuator when carrying out electric operating, not only action thereupon of handwheel, and need not the COMM communication that any manual operation can be changed automatically during manually-operable.
The technological scheme that the utility model adopted is: the COMM communication of electric actuator automatic/hand comprises output shaft, duplicate gear, shaftgear, planetary carrier, gear, free wheel device, dial, handwheel assembly, limit square device and dog; Described duplicate gear, gear, free wheel device and handwheel assembly are sleeved on the output shaft successively; Described planetary carrier links to each other with output shaft with spline, planetary pinion on the planetary carrier and duplicate gear and gear engagement; The gearwheel of described duplicate gear and shaftgear engagement; Described limit square device is arranged on the side of free wheel device, and described dog is arranged between free wheel device and the dial, and described dial and handwheel assembly are connected.
Described free wheel device comprises: limit square dish, clutch wheel, roller and spring; Described dog inserts between the roller, and described clutch wheel and gear connect as one with tongue-and-groove; Described limit square circles or whirl in the air and is enclosed within on the clutch wheel, clutch wheel has the tenon of two symmetries, be formed with two inclined-planes in its both sides respectively and form two wedge slots with the endoporus of limitting the square dish, the width of the close tenon end of wedge slot is greater than the roller diameter, and the width of small end is less than the roller diameter; The central authorities of tenon are provided with a through hole, float to be incorporated with pressure spring.
The beneficial effects of the utility model are: owing to be connected with double rolling key clutch in the actuator, during the actuator electric operating, roller in the clutch blocks Internal and external cycle in the wedge slot outside, dog promotion roller fluffs Internal and external cycle in the time of manually, to rotating in the same way, make the speed and the torque range of actuator wideer, need not any manual operation during manually-operable, improved field technician's working efficiency.

Embodiment
Below, with embodiment the utility model is further described in detail in conjunction with the accompanying drawings.
Fig. 1 is the connection diagram of the utility model electric actuator automatic/hand COMM communication; Fig. 2 is the utility model electric actuator automatic/hand COMM communication A-A cut-away view.
As depicted in figs. 1 and 2, the COMM communication of the utility model electric actuator automatic/hand is characterized in that: comprise output shaft 1, duplicate gear 2, shaftgear 3, planetary carrier 4, gear 5, free wheel device 6, dial 7, handwheel assembly 8, limit square device 9 and dog 10; Described duplicate gear 2, gear 5, free wheel device 6 and handwheel assembly 8 are sleeved on the output shaft 1 successively; Described planetary carrier 4 links to each other with output shaft 1 with spline, planetary pinion on the planetary carrier 4 and duplicate gear 2 and gear 5 engagements; The gearwheel of described duplicate gear 2 and shaftgear 3 engagements; Described dial 7 is connected with handwheel assembly 8; Described dog 10 is arranged between dial 7 and the free wheel device; Described free wheel device 6 comprises: limit square dish 61, clutch wheel 62, roller 63 and spring 64; Described limit square device 9 is arranged on the side of free wheel device 6, and fixedly the limit square dish 61 of free wheel device is avoided impulsive load, prevents from transmission system is damaged.Described limit square dish 61 skies are enclosed within on the clutch wheel 62, clutch wheel 62 have the tenon 62 of two symmetries ', be formed with two inclined-planes in its both sides respectively and form two wedge slots with the endoporus of limitting square dish 61, the width of the close tenon end of wedge slot is greater than roller 63 diameters, and the width of small end is less than roller 63 diameters; The central authorities of tenon are provided with a through hole 62 "; floating is incorporated with pressure spring 64; small end of wedge slot pushed two rollers to by pressure spring; no matter the trend oriented which direction of clutch wheel is rotated; the roller 63 under the spring thrust effect all squeezes clutch wheel 62 and is one with limit square dish 61, and limit square dish 61 by limit square device 9 fixing thereby clutch wheel can not rotate; Described dog 10 inserts between the roller 63 of clutch wheel 62, and described clutch wheel 62 and gear 5 connect as one with tongue-and-groove.
The working principle of the utility model electric actuator automatic/hand COMM communication is: when actuator is in electronic working state, motor rotates by the gearwheel that shaftgear drives duplicate gear, the planetary pinion that its small gear drives planetary carrier rotates, because therefore the rotation path of planetary pinion-gear-double rolling key clutch can only drive output shaft by spline pair by planetary carrier and rotate by the restriction of limit square device.When actuator is in manual state, handwheel devices rotates counterclockwise, the roller that dog promotes the right side moves to the big end of wedge slot, clutch wheel can be rotated counterclockwise, thereby make the roller on the nearly left side of big termination of left side wedge slot, thereby make clutch wheel can driven gear and the gear of planetary carrier rotate counterclockwise because the gearwheel of duplicate gear is limited by shaftgear, therefore can only drive output shaft by spline pair and rotate by planetary carrier.
