Operating principle:
Under powering-off state, by hand rotation manual worm screw 21, manual worm 21 is meshed with the worm gear 22a of worm-wheel shaft 22 thus drives worm-wheel shaft 22 to rotate, then drives planetary gear 23 synchronous axial system by the planet tooth 22b on worm-wheel shaft 22 other end; And planetary gear 23 matches with the inner gear housing 24 of periphery, because inner gear housing 24 is stationary state, planetary gear 23 forms a reducing gear in autorotation in inner gear housing 24; The rotation of worm-wheel shaft 22 also can drive driving head 25 to rotate, and driving head 25 is connected with the outer tube of motor, thus realizes the emergent rising of rolling door under powering-off state or decline.
The head number of manual worm 21 is 1, and the number of teeth of the worm gear 22a of worm-wheel shaft 22 is 19 teeth, then the effect of the reducing gear formed by planetary gear 23, and its total gearratio can reach 1:81, thus makes whole operation more laborsaving.
When rolling door energising running, the internal tooth casing 26 matched with rolling door stationary pipes drives the intermediate drive gear 31 be meshed to rotate, the transmission of 32, the II grade of position limited gear of I grade of position limited gear then through engaging successively, 33, III grade of position limited gear, final drive IV grade of position limited gear 35 rotates; When rolling door moves to upper limit or lower limit, the salient point 35c of IV grade of position limited gear 35 just can touch the contact 61 on microswitch 6 thus makes motor power-off and stop operating, and then safety when ensureing rolling door rising or decline.
Spacing setting operation:
Upper limit sets: first stirred by the center position of upper limit shifting block 51 to device, starter motor operates to rolling door ascent direction, the rotation of motor drives rolling door stationary pipes to rotate, and then drive internal tooth casing 26 to rotate, then intermediate drive gear 31, I grade of position limited gear 32, II grade of position limited gear 33, III grade of position limited gear 34, IV grade of position limited gear 35 is driven successively, along with the rotation of IV grade of position limited gear 35, reach upper limit when the upper limit collision block 41 on the first runner 35a is collided with upper limit shifting block 51, now cut off the electricity supply and motor is shut down; Then upper limit shifting block 51 is stirred to direction of both ends, namely complete the setting of upper limit.
Lower limit sets: same, first the center position of lower limit shifting block 52 to device is stirred, starter motor operates to rolling door descent direction, the rotation of motor drives each pinion rotation, along with the rotation of IV grade of position limited gear 35, reach lower limit when the lower limit collision block 42 on the second runner 35b is collided with lower limit shifting block 52, now cut off the electricity supply and motor is shut down; Then lower limit shifting block 52 is stirred to direction of both ends, namely complete the setting of lower limit.
Most preferred embodiment of the present invention is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from the scope of the present invention.
