Detailed description of the invention
The present embodiment is a kind of bidirectional self-locking clutch, and it includes: slip ring (1), shaft block ring I (2), deep groove ball bearing
(3), needle roller pin (4), star-wheel (6), outer ring I (5)；As it is shown in figure 5, described outer ring and shaft block ring are respectively arranged with two respectively, point
Not being outer ring I (5) and outer ring II (51), shaft block ring I (2) and shaft block ring II (21), described outer ring I (5) connecting shaft is used
Back-up ring I (2), shaft block ring I (2) connects deep groove ball bearing (3), deep groove ball bearing (3) connection slip ring (1) one end, and slip ring (1) is another
One end connects star-wheel (6), and star-wheel (6) connects shaft block ring II (21), and shaft block ring II (21) connects outer ring II (51)；
As it is shown on figure 3, described slip ring (1) is drive end, slip ring (1) main body is the torus group that two diameters are different
Becoming, large-diameter circular ring body side end face is provided with uniform 6, for placing the circular hole of needle roller bearing pin, minor diameter side external diameter
It is provided with the bearing gear for installing deep groove ball bearing (3) and the groove of shaft block ring is installed；As shown in Figure 4, described star-wheel
(6) being driven end, star-wheel (6) body side is provided with the polygon exterior angle equal with slip ring circular hole quantity, opposite side be provided with for
The bearing gear of deep groove ball bearing (3) is installed and the groove of shaft block ring is installed；Described needle roller pin (4) has 6, places respectively
In each circular hole on slip ring (1), and can be the most movable；Described axis hole two ends, outer ring are provided with deep groove ball bearing room, middle
Through hole and 6 needle roller pins radially contact with or depart from, and matching mechanism realizes clutch.
In practical operation, first deep groove ball bearing (3) it is pressed on slip ring (1) axle journal and blocks upper shaft block ring I
(2), deep groove ball bearing (3) it is pressed on star-wheel (6) axle journal simultaneously and blocks upper shaft block ring II (21)；At deep groove ball bearing
(3) after being connected with slip ring (1) and star-wheel (6) respectively, press-in outer ring II (51) bearing chamber；As shown in Figure 1 and Figure 2, then by needle roller pin
(4) being respectively put in slip ring (1) pin-and-hole, needle roller pin (4) can be the most movable in pin-and-hole；After needle roller pin (4) installation, pressure
Entering outer ring I (5) other end bearing chamber, needle roller pin (4) is tangent with star-wheel (6) hex surface；Outer ring I (5) end face is provided with flange and adopts
Being connected with reduction box flange or gear casing with screw, outer ring I (5) is in stationary state forever.
The motor process utilizing prime mover and reduction box to control bidirectional self-locking clutch is also needed in specific operation process,
Described prime mover driving shaft and slip ring (1) axis hole are connected as drive end；The power shaft of reduction box is connected as with star-wheel (6) axis hole
Driven end；
When prime mover startup work, the rolling in driving drive end slip ring (1) to rotate to the left or to the right and promoting slip ring pin-and-hole
Needle pin (4) moves in a circle；Needle roller pin (4) in the upper pin-and-hole of slip ring (1) is now equivalent to the claw floated, and vises star-wheel (6)
To rotation about outer-hexagonal.
When prime mover transfixion, if the power shaft of reduction box applies moment of torsion to the left or to the right to driven end star-wheel (6),
Now mechanism described in this patent has become star-wheel (6) is drive end；The outer-hexagonal face that star-wheel (6) is held is with axle center circumferentially rotary
Become a pivot angle, moment with in slip ring needle roller pin (4) tangent, and promote needle roller pin (4) to press close to outer ring inwall to produce self-locking
Dead angle cuts off moment of torsion transmission, it is achieved self-locking.
