Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
nullRefer to Fig. 1 to Fig. 6，A kind of from walking system，Including being connected the casing 1 and drive division 2 formed by the right shell of casing 11 and casing left housing 12，The centrifugal assembly 3 being located in casing 1 and the planetary assemblies 4 being connected with centrifugal assembly 3，The two ends of planetary assemblies 4 drive road wheel 7 to move by left axle 5 and right axle 6，Drive division 2 includes motor 21 and the motor gear 22 being arranged on motor output shaft，Motor gear 22 is connected with the inclined shape of gear wheel 301 of centrifugal assembly 3，Centrifugal assembly 3 includes gear wheel 301，Connect on gear wheel 301 and have connecting shaft 302，Fixed cover 303 it is arranged with in connecting shaft 302，The gap between two ends of connecting shaft 302 is combined with power transmission shaft 304，Two power transmission shafts 304 are separately fixed on casing left housing 11 and the right shell of casing 12 by deep groove ball bearing 305 and partly stretch out the right shell of casing 12 and casing left housing 11，It is fixedly connected with fixed plate 306 and 2 axis of guides 307 by machine tooth screw on gear wheel 301，The correspondence of two ends up and down of 2 axis of guides 307 is arranged with 2 centrifugal-blocks 308，It is arranged with reset tension spring 309 on 2 axis of guides 307，The two ends of reset tension spring 309 are pressed on centrifugal-block 308.Being connected by torsion spring 310 on power transmission shaft 304 and have rotation fixed cover 311, rotate fixed cover 311 and be positioned at inside gear wheel 301, it is internal that centrifugal-block 308 is positioned at rotation fixed cover 311.nullPlanetary assemblies 4 includes the central gear 401 being located on power transmission shaft 304，Central gear 401 is outside is evenly arranged with 3 planetary gears 402，3 planetary gears 402 are installed between planet carrier component 403 and planet carrier fixed mount 404，It is engaged with ring gear 405 outside 3 planetary gears 402，Ring gear 405 is fastenedly connected with planetary gear case lid 406，Planet carrier component 403 is fixed with planetary gear case lid 406 by oiliness bearing 407，Two planetary gear case lids 406 are fixed respectively at the right shell of casing left housing 11 and casing 12 by machine tooth screw，Planet carrier component 403 two ends are connected with left axle 5 and right axle 6 by fixed pin shaft 408，Transfer a torque to left axle 5 and right axle 6，Road wheel 11 is driven by left axle 5 and right axle 6，The axle head of left axle 5 and right axle 6 is equipped with shaft block ring.
The present invention is as follows from walking system specific works principle: motor gear 22 is fitted on motor 21, motor 21 is fixed on the right shell of casing 11 by machine tooth screw, gear wheel 301 is fixed in the right shell of casing 11 and casing left housing 12, skewed connection at an angle between motor gear 22 and gear wheel 301,30-60 ° of angle of inclination, preferably 40 °.When assembling, the angle of assembling is along the hand of spiral of gear, when working gear, motor gear 22 engages with gear wheel 301 steadily, the generation of partial noise is decreased at motor in the case of running up, and left and right casing needs certain cylindrical space when assembling this helical teeth, therefore right case decreases the generation of noise in certain degree.
When after startup motor, rotating speed is low, motor gear 22 passes to gear wheel 301 by transmission by active, at this moment gear wheel 302 starts to rotate, owing to the fixed cover 303 on gear wheel 301 and connecting shaft 302 are matched in clearance, so the power transmission shaft 304 at connecting shaft 302 two ends will not rotate, the most whole casing does not works.When motor 21 rotating speed reaches duty, two centrifugal-blocks 308 on gear wheel 301 are under the influence of centrifugal force, centrifugal-block 308 overcomes the resistance of respective reset tension spring 309 to start along the axis of guide 307 outwards to do centrifugal motion, after centrifugal-block 308 contacts with rotation fixed cover 311, just will not continue to outwards do centrifugal motion, boss is had on fixed cover 311 owing to rotating, centrifugal-block 308 limit forms jaw clutch mechanism with rotating fixed cover 311, i.e. exocentric structure engagement, then start to transmit moment of torsion, this is that power transmission shaft 304 starts to rotate, and spreads out of moment of torsion.The pulling force of two centrifugal-block 308 respectively greater than respective reset tension springs 309 in this process.When power transmission shaft 304 just starts to rotate, owing to centrifugal-block 308 and rotation fixed cover 311 are instantaneous touch, at this moment can produce bigger impact, therefore rotate fixed cover 311 internal structure increase torsion spring 310, reduce the impact now produced, reach the effect making casing steadily operate.When motor 21 quits work, centrifugal-block 308 is the gravity of customer service centrifugal-block 308 self under the effect of reset tension spring 309, it is returned to original position along the axis of guide 307, at this moment power transmission shaft 304 can be freely rotatable, owing to centrifugal-block 308 is separated with rotation fixed cover 311, do not have moment of torsion transmission, i.e. exocentric structure is kept completely separate.
As shown in Figs. 7-8, power transmission shaft 304 can be freely rotatable in the case of motor does not works volume, i.e. reaches centrifugal purpose, now can realize walking by artificial promotion, and power transmission shaft 304 normally can work under the drive of motor when motor normally works, it is achieved automatically walk.The power transmission shaft 304 stretched out is installed central gear 401, central gear 401 surrounding is uniformly distributed three planetary gears 402, three planetary gears 402 are arranged on planet carrier component 403, and 3 planetary gears 402 are between planet carrier component 403 and planet carrier fixed mount 404, as shown in the figure.Three planetary gears 402 coordinate with ring gear 405, driving torque, ring gear 405 fastens with planetary gear case lid 406 by the structure of self, planet carrier component 403 is fixed with planetary gear case lid 406 by oiliness bearing 407, two planetary gear case lids 706 are fixed respectively at the right shell of casing left housing 12 and casing 11 by machine tooth screw, now when motor 21 rotates, the planet carrier component 403 at two ends, by two-stage gear drive, starts to rotate.At planet carrier component 403 two ends, by fixed pin shaft 408 respectively at left axle 5, right axle 6 connects, and delivers torque to Y-axis, can connect wheel at the two ends of Y-axis.The power that now motor is initial passes through two-stage transmission to wheel.
The advantage of this structure is that one is the advantage utilizing Planetary Gear Transmission bigger, and motor height rotating speed is converted into the slow-speed of revolution, and transmission is out；Two is that this structure is combined with exocentric structure, compares more traditional two-stage transmission, and this space is substantially reduced；Three is can at lower cost, and sound is little, more meets present design requirement.
Being different from prior art, the present invention is from walking system and garden instrument thereof, it is possible to realizing walking automatically or artificial promotion is lower mobile, simple in construction, work efficiency is high, reduces cost, reduces operating noise, save overall space.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
