It is equipped with hand input shaft.
Further, planetary gear quantity is three in the planetary gear set.
Further, the big roller gear and hand input shaft can upper and lower translation carry out de- tooth operation.
Further, on the motor input shaft inserting end to be equipped with sun gear end between be provided with three-level bearing with
Speed reducer case lid is flexibly connected.
The utility model has the beneficial effects that
1, utility model device realizes self-locking function using the self-locking performance of worm and gear, while being equipped with hand input shaft,
When motor power loss band-type brake, the output shaft of speed reducer can be transmitted motion to by hand input shaft, thus by motion transmission
To subsequent bindiny mechanism, and can be reversed it is self-locking make movement be only capable of from input shaft toward output shaft transmit.
2, in utility model device hand input shaft and big roller gear can upper and lower translation setting, ensure that worm gear snail
Lever apparatus serious wear and when reverse drive occurs, manual setter part can take off tooth with it as early as possible or ahead of time, avoid transmitting
The torque come accidentally injures hand operator.
3, motor input shaft is connect with the Multistage bearing of speed reducer case lid, avoid input shaft it is too long in the case where its may
The relative jitter of generation or the failure of bias, improve the stability of hand-rail type self-locking speed-down machine.

Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As shown in Figure 1, the specific structure of the utility model are as follows: a kind of hand and self-locking planetary reducer of band, it includes
Motor input shaft 9 and speed reducer output shaft 8, are socketed with sun gear 1 on the motor input shaft 9, the sun gear 1 in worm gear
Planetary gear set 2 is provided between ring gear 3, described 3 one end of worm gear internal gear is flexibly connected by bearing with speed reducer output shaft 8;
3 outside of worm gear internal gear forms worm and gear with worm screw 4 and connect, and described 4 one end of worm screw is provided with small cylinder gear 5, institute
Small cylinder gear 5 is stated to connect with the big composition of roller gear 6 gear drive in lower section;6 center of big roller gear is filled to speed reducer
It sets outside and is provided with hand input shaft 7.
Preferably, planetary gear quantity is three in the planetary gear set 2.
Preferably, the big roller gear 6 and hand input shaft 7 can upper and lower translation carry out de- tooth operation.
Preferably, on the motor input shaft 9 inserting end to be equipped with 1 end of sun gear between be provided with three-level bearing with
Speed reducer case lid is flexibly connected.
When device works: planetary gear set 2 be three identical planetary gear sets at, planetary gear set output shaft the other end,
Single planetary gear can be moved freely, when planetary gear is around sun gear 1 or worm gear 3 circular motion of internal gear, will be driven
Speed reducer output shaft 8 moves together.Three planetary gears in planetary gear set 2 be evenly arranged on sun gear 1 periphery and all with sun gear
1 external toothing;Planetary gear set 2 in the inside of worm gear internal gear 3, and 3 planetary gears in planetary gear set 2 with worm gear internal tooth
3 internal messing of ring;Worm gear internal gear 3 and worm screw 4 are external toothings;Worm screw 4 and small cylinder gear 5 are coaxial, there is identical angular speed;
Small cylinder gear 5 and big 6 external toothing of roller gear, and the number of teeth of small cylinder gear 5 is less than big roller gear 6, big Cylinder Gear
The angular speed coaxial and having the same with hand input shaft 7 of wheel 6.
When motor power loss band-type brake, motor input shaft 9 is fixed, hand when starting to shake input shaft 7, hand input shaft 7 and great circle
Stud wheel 6 does moved in coaxial, and movement is transmitted to small cylinder gear 5 by big roller gear 6, because of small cylinder gear 5 and worm screw 4
Coaxially, so worm screw 4 and small cylinder gear 5 circular motion that do angular speed together equal, and because worm screw 4 and worm gear internal gear
3 be external toothing, therefore movement is transmitted to the circumference fortune that worm gear internal gear 3 makes worm gear internal gear 3 do ten times around sun gear 1
Dynamic, worm gear internal gear 3 and planetary gear set 2 are internal messing, so worm gear internal gear 3 drives planetary gear set 2 to move in a circle, institute
It is and then moved in a circle together with speed reducer output shaft 8, movement is spread out of.
Since worm and gear used has self-lock ability, when the reversing of motion is inputted from worm screw 4 toward worm gear internal gear 3, by
To the self-locking performance principle of worm and gear, worm gear internal gear 3, which will suffer restraints, to be moved, and since motor input shaft 9 is fixed, because
This sun gear 1 also suffers restraints, so the movement of planetary gear set 2 will also suffer restraints and cannot move, to realize speed reducer
Reverse self-locking.
When motor movement, sun gear 1 moves in a circle, and movement has the tendency that transmitting from worm gear internal gear 3 toward worm screw 4,
Due to the self-lock mechanism of worm and gear, worm gear internal gear 3 suffers restraints self-locking.Therefore planetary gear set 2 is exported with speed reducer
Axis 8 moves in a circle around sun gear 1, and movement is transmitted to speed reducer output shaft 8, realizes the normal use of motor.
