This reducer structure compactness, volume is little, in light weight, transmitting ratio is big, driving efficiency is high, shock resistance, vibration resistance strong, running steadily.
Two, spiral friction-type inertial booster clutch-brake and face mounted motor assembly
Spiral friction-disc inertial booster clutch-brake is made of spiral friction-type clutch-brake and flywheel inertial booster cone of friction holdback.
Spiral friction-type clutch-brake is made of bull male screw sleeve-type fixed friction dish 3, bull female screw pin-and-hole formula activity friction disc 13, friction lining 19, check wheel 6, steel ball 7, set collar 8.Bull male screw sleeve-type fixed friction dish 3 is solidly set on electrical motor 1 rotor shaft, two friction linings 19 clip check wheel 6 and are enclosed within outside the bull male screw sleeve-type fixed friction dish 3, bull female screw pin-and-hole formula activity friction disc 13 rotation sets and compress friction lining 19, check wheel 6 on bull male screw sleeve-type fixed friction dish 3.Plane thrust bearing 4 is positioned on to be decided in the bearing hole of flange 10 and is adjacent to the shaft shoulder plane of bull male screw sleeve-type fixed friction dish 3 in week.Step disk 2 is enclosed within on the check wheel 6 with its interior set collar 8 of fixing with pin, all six the check angles of wedge 11 of cloth of sparing of check wheel wheel, and the check angle of wedge becomes alley 21 with stationary annular, and steel ball 7 places alley.Step disk 2 usefulness socket head cap screws are fixed on the attachment flange 10.

This clutch-brake novel structure compactness, friction face is many, frictional area is big, when in lift car, load being arranged, it relies on gravity, impulsive force and the force of inertia of load, gives the multi-head spiral moment of rotation, utilizes the pressure of multi-head spiral to produce friction moment to friction clutch, produce lock torque to friction brake, and load is big more, and moment of rotation is big more, helical pressure is big more, friction force moment, lock torque are also big more, does not need other power fully.As want loosen the clutch or drg, as long as allow electrical motor rotate to the direction of loosening spiral, multi-head spiral loosens and get final product, so it not only can make power-transfer clutch but also can make drg, also makes coupler usefulness.
Flywheel inertial booster cone of friction holdback then works during no-load.The flywheel 44 that is contained on the terminal spindle nose of input shaft both can absorb the impulsive force that the frequent rotating of electrical motor is produced, make the running of planetary reduction gear more steady, can utilize its force of inertia to give the multi-head spiral moment of rotation again, produce friction moment to friction clutch, produce lock torque to friction brake, this promptly is called inertial booster.When elevator moves at no-load, as press stop going up, behind the key that stops, elevator is because the force of inertia effect meeting of electrical motor etc. continues to rise or descend, the utility model is exactly to utilize the force of inertia of flywheel to offset the force of inertia that electrical motor etc. produces.
This spiral friction-type inertial booster clutch configuration is novel compact, and volume is little, and deceleration and stopping performance is good, and glancing impact does not have a bit slippage, and the reason of zero slip is:
1,15 rotations of load drive input shaft are to be produced by the over-speed gear ratio transmission opposite with the planetary reduction gear reduction ratio, and load drives traction sheave 31 and omits commentaries on classics a bit, and input shaft will rotate some commentaries on classics;
2, the multi-head spiral helical pitch is big, and it is as long as change the very big distance of a bit will advancing a little, and the stopping distance of friction lining only is again 0.1-0.2mm, therefore input shaft rotates some commentaries on classics, and traction sheave just rotates a bit, and input shaft rotates a bit, traction sheave is almost motionless, so can instantaneous braking.
Three, towing machine holder part
Face mounted motor rotor shaft, spiral friction-type inertial booster clutch-brake, pin type-tooth difference involute planetary retarder all are positioned on traction sheave 31 endoporus, and they all are positioned on the towing machine support 39.Hollow anchor shaft 26 is fixed on the reaction plate 40 together with bearing pin 25, the guide 24 of dress on it, reaction plate is fixed on the towing machine support 39, therefore, only see traction sheave and two parts of electrical motor from seeing the utility model in appearance, compact conformation, volume is little, floor area is little, in light weight.
The electrical motor other end rotor shaft end side of dress tenon 50 overlaps handle on the square tenon, during power failure, crank handle, the utility model can normally move, and not only the passenger that can conveniently be stranded in the car because of contingency escapes, goods transports, and also uses when the maintenance jiggering, is convenient to the installation and maintenance of elevator.
Lift car no-load or have load rising, decline and glancing impact clutch-brake and awl holdback mode of operation to see Fig. 5, Fig. 2, Fig. 3
Process with rising during decline is identical, difference is the rotor shaft left-hand revolution of electrical motor 1, bull male screw sleeve-type fixed friction dish 3 screws out bull female screw pin-and-hole formula activity friction disc 13, steel ball 7 is squeezed in alley 21 by the check angle of wedge 11 of left-hand revolution, check wheel 6 is blocked stopping operating.And bull male screw sleeve-type fixed friction dish 3 still rotates in the hole of check wheel 6, the bull female screw pin-and-hole formula activity friction disc 13 that screws out is pressed on the conical surface of taper hole star-wheel 23 planes and coupler 18, taper hole star-wheel 23 rotates counterclockwise, and the star-wheel angle of wedge 35 promotes roller 22 and freely rotates in raceway 36.Coupler 18 drives input shaft 15 through planetary reduction gear transmission traction sheave 31 left-hand revolutions.Steel rope loosens on the traction sheave, electrical motor 1 drives lift car decline when no-load, there is the car of load to drive electrical motor 1 rotation, the car descending speed is when surpassing the rotating speed of electrical motor 1, the spiral friction clutch-brake is promptly braked, and has the car of load can only keep descending with electrical motor 1 identical speed behind planetary reduction gear.
No matter be to rise, the lift car glancing impact that load is arranged that descends, in the moment of electrical motor 1 outage, there are the gravity and the force of inertia of load car to drag traction sheave 31, inner gear 32, satellite gear 33, input shaft 15, coupler 18 rotations, the star-wheel angle of wedge 35 of taper hole star-wheel 23 promotes roller 22 and freely rotates in raceway 36, and the pin 16 of the coupler that in check ring 20 raceways 49, freely rotates, the movable friction disc 13 rapid rotation sets that drive bull female screw pin-and-hole formula are outside bull male screw sleeve-type fixed friction dish 3, check between two friction linings 19 wheel 6 is clamped, and the drive check is taken turns 6 left-hand revolutions, check took turns for 6 moments that just will rotate, the check angle of wedge 46 drive steel balls 7 roll out the check angle of wedge 46 and squeeze in alley 47, block check wheel 6, the car that load is arranged is that zero slip ground stops.
The lift car no-load rises or decline glancing impact clutch-brake is seen Fig. 6, Fig. 2, Fig. 3 with awl holdback mode of operation.
When uncharged car rises to certain position and need stop to rise, after cutting off the power supply of electrical motor 1, flywheel 44 and motor rotor shaft 5 clickwise still under the effect of force of inertia, the former rotative speed is more faster than the latter, bull female screw pin-and-hole formula activity friction disc 13 screws out from bull male screw sleeve-type fixed friction dish 3 rapidly, tightly be pressed in the bigger friction moment of the conical surface of giving coupler 18 on taper hole star-wheel 23 end faces, and drive taper hole star-wheel 23 clickwises, this in a flash roller 22 be extruded in the raceway 36 by the star-wheel angle of wedge 35 and block, taper hole star-wheel 23 stops operating immediately, and compressing coupler 18 stops operating.And then coupler 18, input shaft 15, flywheel 44, traction sheave 31 also stop operating.But the moment of inertia of electrical motor 1 arrives bull male screw sleeve-type fixed friction dish 3 rapid rotation sets outside the bull female screw pin-and-hole formula activity friction disc 13 again, check between two friction linings 19 wheel 6 is clamped, but the moment of inertia of electrical motor 1 is less than the friction moment of the taper hole star-wheel 23 and coupler 18 conical surfaces, so electrical motor 1 stops operating.When taper hole star-wheel and coupler conical surface cone angle were 6 °-8 °, the friction self-locking power that produces between two conical surfaces was comparatively suitable.
No-load car decline glancing impact, rely on the flywheel 44 of high speed left-hand revolution to drive input shaft 15 and coupler 18 left-hand revolutions, taper hole star-wheel left-hand revolution, the star-wheel angle of wedge 35 promotes roller 22 and freely rotates in raceway 36, then drive the rapid rotation set of bull female screw pin-and-hole formula activity friction disc 13 high speed conter clockwises outside bull male screw sleeve-type fixed friction dish 3 by the pin on the coupler 18 16, check between two friction linings 19 wheel 5 is clamped, offset the force of inertia of electrical motor 1, electrical motor 1 is stopped operating.And just the check of left-hand revolution wheel 6 this in a flash its check angle of wedge 11 drive steel balls 7 and squeeze and in alley 21, block check wheel 6, the check wheel stops operating, and forces flywheel 44, planetary reduction gear and traction sheave 31 to stop operating.
This shows that the utility model no-load rising glancing impact inertial booster cone of friction holdback plays brake action, the moment of inertia of flywheel 44 played brake action when no-load descended.
The manual work state is the same with electronic mode of operation, and difference is, flywheel is littler than the force of inertia of electrical motor rotation, and the inertial booster cone of friction is inoperative.
