Embodiment
Referring to figs. 1 through Fig. 6, the easily detachable motor with hollow rotor embodiment of a kind of rotor of the utility model is described further.
As shown in Figures 1 to 6, the easily detachable motor with hollow rotor of a kind of rotor, comprise housing 1, described housing 1 internal fixtion has stator, rotor is provided with in described stator, described rotor is hollow tubular structure, described rotor is fixedly connected with power output member 9, it is characterized in that: described rotor comprises three identical sub-transfer parts 2, described sub-transfer part 2 is fan-shaped perpendicular to the cross section of rotor axis, connected by shell fragment 7 between adjacent sub-transfer part 2, spiral path transfer structure 6 is provided with in described rotor, described spiral path transfer structure 6 comprises fixed mount 4, slide bar 3 adjusts screw rod 61 with turning round, described fixed mount 4 is hollow column, fixed mount 4 is provided with slide opening 42 and centre bore 41, described centre bore 41 is positioned at end face, described slide opening 42 is positioned at side, described slide bar 3 integral type is connected to sub-transfer part 2, described turning round adjusts screw rod 61 to be provided with screw rod 61 and multistage boss 62, described slide bar 3 is conflicted through slide opening 42 and multistage boss 62, screw rod 61 is arranged in centre bore 41.
Sub-transfer part 2 is separated from one another, connected by shell fragment 7, realize the flexible of hollow rotor external diameter, the moving direction that slide opening 42 on fixed mount 4 controls slide bar 3 is positioned in radial direction, slide bar 3 is with in the radial direction of mover transfer part 2 and is stretched back and forth, the spiral path transfer structure 6 that hollow rotor centre is arranged, the movement of multistage boss 62 with moving slide-bar 3 of adjusting on screw rod 61 can be turned round by mobile, slide bar 3 multistage boss 62 vary in size diameter boss effect under there is in radial direction movement, band mover transfer part 2 is moved diametrically, thus realize the change of hollow rotor external diameter size, when hollow rotor external diameter is less than the internal diameter of stator, just hollow rotor can be taken out in stator, the hollow rotor that easy maintenance and replacement is damaged, convenient to operation, sub-transfer part 2 is provided with power output member 9 fixing hole 5, power output member 9 and three sub-transfer parts 2 are connected by screw fixing, the fail safe that the Power output of guarantee rotor and power output member 9 work.
When the diameter of the multistage boss 62 of inside becomes large, extruding slide bar 3, makes slide bar 3 move side along slide opening 42 outwardly, band mover transfer part 2 is also moved laterally along rotor radial, three sub-transfer part 2 movements jointly, makes the external diameter of hollow rotor become large, be embedded in stator, do not deviate from; When the diameter of the multistage boss 62 of inside diminishes, slide bar 3 moves along slide opening 42 towards center, band mover transfer part 2 is also moved to the inside along rotor radial, three sub-transfer part 2 movements jointly, the external diameter of hollow rotor is diminished, and hollow rotor external diameter is less than diameter of stator bore, and hollow rotor deviates from stator, convenient for maintaining personnel can take out maintenance or change, convenient to operation.
Wherein, described multistage boss 62 comprises path platform 62A, transition bench 62B and large footpath platform 62C, described path platform 62A, transition, large footpath platform 62C successively integral type connect, described screw rod 61 surface is provided with external screw thread, be provided with internal thread 43 in described centre bore 41, described internal thread 43 engages with external screw thread.
Multistage boss 62 is provided with path platform 62A, transition bench 62B and large footpath platform 62C, by controlling the amount of movement of the diameter adjustment slide bar 3 of multistage boss 62 on slide bar 3, the amount of movement of slide bar 3 determines the variable quantity of hollow rotor external diameter, the external diameter realizing hollow rotor stretches, when hollow rotor external diameter is less than the internal diameter of stator, just hollow rotor can be taken out in stator, the hollow rotor that easy maintenance and replacement is damaged, convenient to operation.
When torsion screw rod 61, screw rod 61 threadingly direction is moved, when moving direction is path platform 62A to large footpath platform 62C, slide bar 3 is through transition bench 62B, and the diameter of multistage boss 62 changes from small to big, and slide bar 3 moves laterally, hollow rotor external diameter increases, and makes hollow rotor be fixed in stator; When moving direction is large footpath platform 62C to path platform 62A, slide bar 3 is through transition bench 62B, and the diameter of multistage boss 62 from large to small, slide bar 3 moves to the inside, hollow rotor external diameter reduces, and deviates from, for maintenance and the replacing of rotor when making hollow rotor external diameter be less than diameter of stator bore in stator.
Wherein, described multistage boss 62 two ends are provided with spacing chimb 63.
Because screw rod 61 is in twisting process, multistage boss 62 also differently to be noticed, possibly because maintenance personal reverses excessively, and causes slide bar 3 to drop causing screw rod 61 position, depart from multistage boss 62, cause great inconvenience, for avoiding this situation to occur, by arranging spacing chimb 63, prevent excessive turn-knob and the slide bar 3 caused drops, the phenomenon such as cannot reset, and avoids unexpected generation
Wherein, described screw rod 61 top is provided with cross notch 64.
At screw rod 61 top, cross notch 64 is set, convenient for maintaining personnel reverse screw rod 61 with screwdriver makes multistage boss 62 move, band moving slide-bar 3 radially moves, and realize the change of hollow rotor external diameter size, when hollow rotor external diameter is less than the internal diameter of stator, just hollow rotor can be taken out in stator, the hollow rotor that easy maintenance and replacement is damaged, convenient to operation.
Wherein, described multistage boss 62 and fixed mount 4 are made up of aluminum alloy materials, and the end face of fixed mount 4 is provided with thermovent 8.
Reduce the weight in hollow rotor centre, reduce hollow rotor energy loss when rotated, reduce operating noise, control precision improves; Heat can distribute by the setting of thermovent 8 easily, and long-time use also can not cause heat to concentrate, and increases the service life.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection range of the present utility model.
