Embodiment
The first embodiment: as shown in Fig. 1 Fig. 2, this double clutch motor is to be made up of parts such as shell 1, stator 2, rotor 3 and output shafts 4, be characterized in: rotor 3 is not to be fixedly connected with output shaft 4, the inner hole sleeve of rotor 3 is contained in the outside of output shaft 4, the endoporus of rotor 3 is greater than the external diameter of output shaft 4, between rotor 3 and output shaft 4, is provided with between centers clutch 6.The two ends of output shaft 4 all can be connected with transmission device, and wherein one end is provided with axle head clutch 5.Here, the clutch that can adopt has multiple, and the axle head clutch 5 that Fig. 3 exemplifies and between centers clutch 6 are all a kind of unidirectional centrifugal clutch.This unidirectional centrifugal clutch has inner sleeve 7 and overcoat 8, and overcoat 8 is sleeved on the outside of inner sleeve 7, between inner sleeve 7 overcoats 8, has glade plane space, and overcoat 8 inwalls outwards have chute 9, and spring 10 is housed in chute 9, and slide block 11 is equipped with in the outer end of spring 10.The slide block 11 is here preferably spherical in shape, and chute 9 is preferably circular hole.Chute 9 should have more than two, and multiple chutes 9 are preferably distributed on around overcoat 8 endoporus, and so stressed meeting is more even.It is very loose that chute 9 enters the angular range of overcoat 8, as long as the centerline direction of chute 9 and the radial direction of overcoat 8 are not parallel, between have an angle.As preferably, chute 9 inner sides shown in Fig. 3 the edge line of a side nearer apart from the overcoat 8 endoporus hearts along extending in overcoat wall with the tangential direction of overcoat 8 endoporus intersection points.Chute 9 the inners that enter overcoat 8 are preferably sealed, and the sealing here comprises the structure that boss etc. can restraining spring 10 ends is set.Chute 9 outer ledge lines have the inclined-plane 12 bending inwards in the chute porch of overcoat 8 inwalls.Between inner sleeve 7 and overcoat 8, bearing is preferably housed.
As seen from Figure 3, when the relative overcoat 8 of inner sleeve 7 clockwise rotates, when the direction engaging with slide block 11 to spring 10 is rotated, slide block 11 is driven or moves forward under spring 10 promotes, be clipped in the wedge shape space between overcoat 8 and inner sleeve 7 at 6 places, inclined-plane, slide block 11 is subject to inside extruding, inner sleeve 7 and overcoat 8 is engaged and be integrated, and synchronously rotates.Otherwise, when the relative overcoat 8 of inner sleeve 7 rotates counterclockwise, while rotation to the interior extreme direction of spring 10 and chute 9, slide block 11 is tangentially dished out by centrifugal action, overcome spring force and move to the interior extreme direction of chute 9, residing space increases, and slide block 11 has departed from inner sleeve 7, inner sleeve 7 and overcoat 8 have also just lost concatenator and have mutually thrown off, no longer interlock.
Obviously, the structure that one-way clutch is installed respectively between this rotor 3 and output shaft 4 and one end of output shaft, can realize plurality of installation forms, and various forms has different functions and purposes.In figure, only exemplify the one of the clutch opposite direction of axle head clutch 5 and between centers clutch 6, in the time that axle head clutch engages with external transmission device, the state of between centers clutch 6 in separating, output shaft 4 rotates, and rotor 3 is motionless.When between centers clutch 6 engages, axle head clutch 5 separates, and rotor 3 drives output shaft 4 with turning.Obviously, this kind of drive serves many purposes in engineering.
Here, output shaft 4 docks or all adopts spline docking with docking of axle head clutch with external transmission device, installs very convenient.Certainly, more should recommend adoption internal spline, can enter motor internal, can make structure compacter.
The second embodiment: Fig. 4 has introduced another kind of one-way clutch, there are inner sleeve 7 and overcoat 8, overcoat 8 is sleeved on the outside of inner sleeve 7, between inner sleeve 7 overcoats 8, there is glade plane space, overcoat 8 inner hole walls are provided with multiple unidirectional internal tooths 13, the angle of inclination difference of two lateral tooth flanks of unidirectional internal tooth 13, with respect to the radial transmission line of overcoat 8 endoporus, a side is steep, and opposite side is mild.Unidirectional internal tooth 13 1 sides of introducing in figure overlap with the radius of endoporus, are an acute angle between another side and radius.Be hinged with ratchet 14 with inner sleeve 7 edges of overcoat 8 matched in clearance by rotating shaft, return spring 11 is housed on ratchet 14.This one-way clutch is similar to the flywheel of bicycle and the transmission mechanism of axis, the steep side that ratchet 14 can be supported unidirectional internal tooth 13 engages inner sleeve and overcoat and synchronously rotates, also can be along the mild side slip of unidirectional internal tooth and inner sleeve and overcoat are separated, its effect is identical with the clutch in the first embodiment.
The third embodiment: Fig. 5 has introduced another kind of pair of clutch motor, has the parts such as shell 1, stator 2, rotor 3 and output shaft 4 to form, and rotor 3 is sleeved on the outside of output shaft 4, is provided with between centers clutch 6 between rotor 3 and output shaft.One end of output shaft 4 is clutch end, and the other end is provided with axle head clutch 5.Between centers clutch 6 and axle head clutch 5 be all one-way clutch.These are consistent with the first embodiment.Difference is: the endoporus of rotor 3 is installed a rotor inner sleeve 15, the outer end section of rotor inner sleeve 15 is connected mutually with the outer end section of rotor 3, the middle part of rotor inner sleeve 15 and rotor 3 have one section of space, one end section enlarged diameter of output shaft 4, and the flange forming is relative with rotor inner sleeve 13.Described between centers clutch 6 is located at the inner side of rotor inner sleeve 15, the inner sleeve 7 of between centers clutch 6 is connected with rotor inner sleeve 15, the overcoat 8 of between centers clutch 6 is connected by bolt with the flange of output shaft 4, the external diameter of the overcoat 8 of between centers clutch 6 and the flange of output shaft 4 all keeps gap with rotor 3, does not contact mutually.Obviously, this structure is the same with the operation principle of the first embodiment, and its effect is to be mainly convenient to make and assembling, and operating state is also more stable.
The 4th kind of embodiment: Fig. 6 introduced another kind of pair of clutch motor, has the parts such as shell 1, stator 2, rotor 3 and output shaft 4 to form, and rotor 3 is sleeved on the outside of output shaft 4, between rotor 3 and output shaft 4, is provided with between centers clutch 6.One end of output shaft 4 is provided with axle head clutch 5.Between centers clutch 6 and axle head clutch 5 be all one-way clutch.Here between centers clutch 6 is mounted in the unilateral bearing 16 between rotor 3 and output shaft 4, can be arranged on the two ends of rotor 3 endoporus.In addition, axle head clutch 5 also can adopt unilateral bearing 16, and its effect is the same with foregoing various one-way clutch.Its advantage is to use commercially available standard rolling bearing, reduces the difficulty of manufacturing, but will determine the place using according to the bearing capacity of bearing and net synchronization capability.
The 5th kind of embodiment: as shown in Fig. 1, Fig. 5, Fig. 6, the body of this motor is very short, is plate-like.The rotor length of existing motor mostly is the more than 2 times of root diameter, and length-to-diameter≤1.5 of this routine rotor: 1, the even diameter of the length≤rotor of rotor.The motor of this plate-like is applicable to being arranged on the occasion that horizontal size is less, and in conjunction with the disengaging performance of previous embodiment, this motor will have purposes more widely, and for a change the operating type of existing motor provides condition.
