Detailed description of the invention
Below in conjunction with accompanying drawing, detailed explanation and explanation are done to structure of the present utility model, but be not the restriction to the utility model structure.
Embodiment 1
Please also refer to Fig. 1 ~ 2, it presents outward appearance and the internal construction of the utility model reductor.
Reductor of the present utility model, comprises drive motors 100, drive disk assembly, power output gear 300 and housing 400, and housing 400 is for installing above-mentioned parts, and the whole parts of reasonable arrangement are farthest to reduce the volume of complete machine.Drive motors 100 for can realize unblanking and locking function can clockwise and anticlockwise motor, be provided with the remote control switch that can receive Remote signal simultaneously.
Refer to Fig. 2 ~ 3, drive disk assembly is formed primarily of central gear group, planetary gear 203 and two groups of driving gear set.Wherein, central gear group comprises coaxial mounted 3 sections of gear wheels 201 and central gear 202, and central gear 202 engages with planetary gear 203, drives planetary gear 203 to revolve round the sun.
Refer to Fig. 4, planetary gear 203 is installed on planetary drive plate 205 by planet pin 204 through endoporus, and two neodymium iron boron magnetites 206 on planetary drive plate 205 are adsorbed on sun gear wheel 201 end face, planetary drive plate 205 and sun gear wheel synchronous revolving, drive planet pin 204 around sun pinion revolution in cannelure section 401 with this, now planetary gear does not have rotation around sun pinion revolution yet.When planetary gear 203 with central gear 202 revolve round the sun arrive activation point time, with the gears meshing of power output gear 300 and drive it to rotate, thus outputting power.
Fig. 5 illustrates the internal construction schematic diagram of housing 400, is provided with the cannelure section 401 for fixing planetary gear wheel shaft bottom housing 400, and two end points of cannelure section are activation point, comprises and unblanks to drive position 402 and lock to drive position 403.When planetary gear with central gear 202 run to unblank drive position 402 or lock drive position 403 time, then run to the summit of traffic direction, can not move forward again.Now planetary gear just obtains the optimum center distance with power output gear 300, drives power output gear revolution thus, the moment of torsion needed for output.
Refer to Fig. 2, driving gear set is two groups, comprises one section of gear train 207 and two sections of gear trains, 208, one section of gear train 207 engages with worm screw 101 and two sections of gear trains 208, and two sections of gear trains engage with sun gear wheel and one section of gear train.Interference fit on the output shaft that worm screw 101 is directly pressed into drive motors 100, because of the stall torsion just 0.01Nm of drive motors, so the axial force that worm screw produces is very small, need not install bearing.
When drive motors energising revolution, slow down and the deceleration of central gear group through worm screw and one section of gear train deceleration, two sections of gear trains 208, drive planetary gear to turn round by central gear.For improving the delivery efficiency of complete machine, worm screw and adopt the little pressure angle being less than 20 ° with one section of gear train of worm engaging.
Driving gear set plays deceleration and gearing, and its quantity can be determined according to deceleration demand.Embodiment 2
Please also refer to Fig. 1 ~ 5, the object of the present embodiment is to explain the structure of the automatic locking being equipped with reductor described in embodiment 1 and illustrate.
Be equipped with an automatic locking for above-mentioned reductor, comprise drive motors and reductor.The drive disk assembly that reductor comprises housing 400, power output gear 300 and is made up of central gear group, planetary gear and at least one driving gear set.
Wherein, central gear group comprises 3 sections of gear wheels 201 and central gear 202, and planetary gear 203 to be fixed on 3 sections of gear wheel 201 wheel faces by magnetic and to engage with central gear 202 and revolve round the sun with central gear.When planetary gear 203 with central gear 202 revolve round the sun to unblank drive position 402 or lock drive position 403 time, engage with power output gear 300 and drive it to rotate with outputting power.As Fig. 5, housing is provided with the cannelure section 401 as center planetary gear axle orbit, unblanks to drive position 402 or two end points driving position 403 to be positioned at cannelure section 401 of locking.
Driving gear set is two groups, comprises one section of gear train 207 and two sections of gear trains, 208, one section of gear train 207 engages with worm screw 101 and two sections of gear trains 208, and two sections of gear trains engage with 3 sections of gear wheels and one section of gear train.Interference fit on the output shaft that worm screw 101 is directly pressed into drive motors 100, because of the stall torsion just 0.01Nm of drive motors, so the axial force that worm screw produces is very small, need not install bearing.When drive motors energising revolution, slow down and the deceleration of central gear group through worm screw and one section of gear train deceleration, two sections of gear trains 208, drive planetary gear to turn round by sun pinion.
Housing 400 outside is provided with remote control switch, can receive the teleinstruction of mobile phone transmission and to its compiling, control the switch of door lock.After remote control switch receives the instruction of door interlock switch, the power supply starting drive motors can be led to, make reductor then output torque.When with mobile phone specific program to the long-range transmission door open command of automatic locking after, remote control switch automatically starting power supply, reductor is output torque then, by door-lock opening.When door is held successfully, reductor will bear stall moment of torsion, the force-bearing situation that external circuit device may detect reductor reaches the limit of, thus switch to reverse electrical source by rotating gauge tap, reductor is oppositely no-load running then, the absorption affinity of magnetite is had an effect again, drives planetary drive plate and planetary gear antiport, completes the action of laying the key under the door.
In order to promote overall efficiency, the worm speed-down of the utility model reductor and one section of train of reduction gears have employed little pressure angle.
In the present embodiment, automatic locking is provided with hand switch installing hole, as no electricity, only need rotary manual switch gently, and planetary gear can be driven out-of-gear position by power output gear, can open Door by Hand not having in electric situation easily realization or close the door.
Below be only that detailed explanation explanation is done to wherein a kind of embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then intention of the present utility model also comprises these changes and distortion.
