Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in figures 1 and 2, a kind of Full-automatic power-driven barring gear, including motor 9, speed reducer 8, clutch 10, axial position
Move follower 12 and travel switch 5.Clutch 10 includes bevel-gear sett 7, splined shaft 1, transmission shaft 11, clutch shaft 6, electromagnetism
Iron 4, the coil one 3 opposite with electromagnet pole, coil 22 identical with electromagnet pole.Conelet in bevel-gear sett 7
On the output shaft of retarder 8, bevel gear wheel and transmission shaft 11 are mounted on same root splined shaft 1 gear set by spline.
The outer circle of transmission shaft 11 is equipped with external thread section c, matches with the internal thread segment b of 6 inner hole of clutch shaft.6 outer circle of clutch shaft is set
There is a jiggering gear α, 6 end face of clutch shaft is embedded with electromagnet 4.As shown in Fig. 1 and Fig. 3, Fig. 4, coil 1, coil 22 and axis
It is fixedly mounted on clutch cabinet to displacement follower 12 and travel switch 5.The rod piece of axial displacement follower 12 passes through
Spring 13 withstands on 6 end face of clutch shaft.Inclined-plane is arranged in the other end of rod piece, and rod piece and travel switch 5 connect, and pass through use
It interacts when output clutch axial displacement with travel switch.As shown in figure 4,13 both ends of spring respectively with rod piece and clutch
Protrusion connection on device cabinet, the movement of rod piece matched by itself inner hole/outer circle with outer circle/inner hole on limit sleeve 14 with
Prevent deflection.The output that clutch axial displacement is realized by axial displacement follower, controls the opening and closing of travel switch.
The course of work of Full-automatic power-driven barring gear is as follows: as shown in Fig. 2, being powered to coil 1, while motor 9 is logical
Forward current, the effect of 6 internal thread segment of clutch shaft and 11 external thread section of the transmission shaft attraction between electromagnet 4 and coil 1
It is lower to form intermeshing frictional force, so that clutch shaft 6 and transmission shaft 11 is not able to maintain coaxial rotating, forms rotational speed difference, so that
Clutch shaft 6 realizes positive axial movement, when advancing to the position of engagement, jiggering gear α and whirler by the engagement of thread segment
What is be arranged on tool rotor is meshed by disk gear 16, carries out jiggering.Meanwhile the rod piece other end of axial displacement follower 12 is oblique
Face is attracted travel switch 5, powers off electromagnet 4.It is powered to coil 22, while motor 9 leads to reverse current, motor 9 inverts
When, the internal thread segment b of clutch shaft 6 and the external thread section c of transmission shaft 11 repulsive force and jiggering between electromagnet 4 and coil 22
Gear α and intermeshing reverse friction power is formed under the action of tangential force between disk gear 16, clutch shaft 6 is made to pass through screw thread
Reversed axial movement is realized in the reversed engagement of section, and make to be arranged on jiggering gear α and rotary machine rotor is taken off by 16 phase of disk gear
It opens, stops jiggering.Meanwhile the inclined-plane of the rod piece other end of axial displacement follower 12 disconnects travel switch 5, makes electromagnet
4 power-off.When barring gear work, rotating machinery start to rotor speed be greater than 6 revolving speed of clutch shaft when, clutch shaft 6 it is interior
The external thread section c of thread segment b and transmission shaft is in jiggering gear α and is formed under the action of by reversed tangential force between disk gear 16 mutual
The reverse friction power of engagement makes clutch shaft 6 realize reversed axial movement by the reversed engagement of thread segment, makes jiggering gear α
It is disengaged with what is be arranged on rotary machine rotor by 16 phase of disk gear, stops jiggering.Meanwhile the axial displacement follower rod piece other end
Inclined-plane travel switch 5 is disconnected, power off electromagnet 4 and motor 9.
