Details are as follows to the embodiment of the invention in conjunction with the accompanying drawings:
Embodiments of the invention 1 are two-way ball friction clutches of fluid (steam) pressure.Its structure is to be equipped with 2 on bearing can only rotate and axially movable gear link 3 can not be arranged on the external diameter of transmission shaft 1.Be connected with profile in one end with screw 4 and be that [its internal face surface of shape is the outer shroud 5 with axis inclined-plane in an acute angle.Be equipped with one at the outer shroud the other end and be connected with key 6, the retainer resetting-mechanism is housed in its body, with the interior ring 7 that the V-shaped groove identical with rolling element quantity arranged on the external diameter working surface of parallel axes with transmission shaft.There is 8 on 10-14 ball to be contained on the retainer 9 between outer shroud and the interior ring.Retainer is that iron plate or plastics are made the ring bodies with parallel axes, cavity with the ball equal number is arranged on the ring bodies circumference, ball is loaded on wherein, and the V-shaped groove (showing as Fig. 2) that connects to the other end from an end face is arranged between ring bodies inner circumference, cavity and cavity.Have on the periphery of inner ring body with retainer on the hole of V-shaped groove equal number, in the stage clip 11 and the part spheroid that are equipped with by straight pin 10 location be exposed at the retainer resetting-mechanism that the outer steel ball 12 of inner ring body is formed.Retainer is contained on the inner ring body periphery, in order to prevent that string is moving about it, back-up ring 13 is housed on the inner ring body of one end, and the other end of interior ring is fixed with a slice baffle plate 15 with screw 14.The alleged two-way clutch of the present invention is that the above-mentioned identical in structure engaging and disengaging gear of a cover respectively is housed on the transmission shaft of the both sides of pressurization device.Liquid described here (vapour) pressurization device is casing walls 17 that respectively connect with screw 18 with the screw 16 fastening two ends by cylinder barrel 19 on baffle plate, two casing wall internal diameters are sleeved on transmission shaft and use on the piston block 20 of key 6 suits, on the plane at 21 places of piston block, be evenly equipped with 3 holes, on the plane at 22 places, also be evenly equipped with three holes, a stage clip 23 respectively is housed in each hole, has formed inner axle to resetting-mechanism by piston block, stage clip and casing wall.
When the transmission shaft rotary work, each part of moment of torsion being passed to interior ring and interior ring is connected by key rotates simultaneously, and this moment, outer shroud was motionless.When liquid vapour pressurizing system with fluid (steam) pressure power by transmission shaft on behind 24 place's oil (vapour) holes, pressure forces the length of spring compressed at cylinder barrel 22 places when Fig. 1 shows that dextrad moves and interior ring together with the ball inclined working of pressed rightwards outer shroud together.Since outer shroud from static (or fine motion) state to rotary state, ball is pressed tighter under the effect of axial force more to outer shroud, when ball compresses outer shroud, the also stenosis wedging of the V-shaped groove that rolls inside ring with the rotation and the axial force of interior ring, ball is in self-locking state on the inclined-plane of V-shaped groove, by the frictional force of ball to the inner and outer rings working surface, moment passes to outer shroud through ball from interior ring, by link moment is spread out of then.When the needs clutch disconnects, fluid (steam) pressure power is cut off, endless belt ball and outer shroud has lost frictional force in when piston block forces cylinder barrel axially to reset by 22 place's springs, and this moment, the ball of retainer resetting-mechanism forced distance of retainer displacement that ball is pressed in the V-shaped groove on the retainer internal diameter by means of the tension force of spring.Certainly, as with the gear link be active transmitting torque also can, no longer repeat at this.When the bi-directional moment of torsion, as being that initiatively the driven axle that one of them link connected can be identical with the transmission shaft sense of rotation with the transmission shaft, the driven axle that another link connected then can obtain the rotation reverse with transmission shaft by shown in Figure 1.Otherwise transmission shaft also can obtain the moment of torsion of positive and negative two directions rotation.
