Description
Technical field
A kind of self-locking electric hoisting machinery transmission brake system relates to electric hoisting, Transport Machinery, can use in fields such as industrial and mining enterprises, family and lifting, transportation, building, finishings.
Background technology
By investigation and consult " universal machine design manual " and " great mass of data (comprising the internet) such as construction machinery and equipment handbook learns that power transmission, the brake system of at present domestic electric hoisting machinery is the following three kinds of forms of employing: the 1st, the electrical motor of the supporting bell-shaped rotor band brake of ordinary gear transmission or be close to the electrical motor of magnetic brake formula band brake; The 2nd, the supporting common motor of worm drive of energy self-locking; The 3rd, the ordinary gear transmission adds that manual operation braking is fast, brake collar or the supporting common motor of brake disc, and the elevator machinery transmission brake system of not finding the supporting common motor of gear transmission as yet has the function of self-locking.Existing situation is: the 1st kind of price is expensive, as the price of 1 brake motor be the common motor price 2-3 doubly, use restricted because of valency is high.The 2nd kind of driving efficiency is low excessively, and at 98-99.5%, and Efficiency of Worm Gearing that can self-locking is less than 50% as a pair of ordinary gear driving efficiency, and used worm drive must be self-locking on the elevator machinery.The power of worm drive auxiliary motor that therefore can self-locking generally is 2 times of gear transmission auxiliary motor power or bigger.The 3rd kind of big price height of the volume that has, what have is dangerous, and needs manual operation, and especially load-carrying decline is difficult to control, accident-proneness.
In order to make full use of ordinary gear driving efficiency height, the advantage that the common motor price is low, overcome the deficiency of above three kinds of type of belt drive, design transmission, the brake system of the outstanding electric hoisting machinery of a kind of advantage, reaching load-carrying promotes, falls and stop free and zero load can descend fast, not only safety but also energy-conservation in the air, and can be widely used in industrial and mining enterprises, family and lifting, transportation, building, finishing, etc. the field, be the purpose of this utility model and task.
Summary of the invention
The utility model will provide by body, gear drive, spiral load-carrying drg, power-transfer clutch to be formed, and the energy self-locking with the matching used a kind of self-locking electric hoisting machinery transmission brake system of electrical motor.
The scheme that solves the utility model technical matters is: complete machine is made up of body, gear drive, spiral load-carrying drg, power-transfer clutch.Gear drive is made up of gear and axle; Spiral load-carrying drg is fixedly mounted on a side of gear drive, combines by gear wheel shaft and gear drive; Power-transfer clutch is installed in the opposite side of gear drive, combines by gear wheel shaft and gear drive; Body is the skeleton of complete machine, and gear drive, spiral load-carrying drg, clutch pack are contained on the body.
Their combination is: spiral load-carrying drg is to be made of input shaft, friction disc (fixing with key), friction lining, ratchet (empty cover), tapped gear; One end of input shaft has outside thread, by bearing installation in body; Friction disc (fixing with key), friction lining, ratchet (empty cover) are installed on the input shaft, are furnished with tapped gear on the outside thread, ratchet and body hinge.
Power-transfer clutch is installed on the output shaft, is installed on the body by gear and gear wheel shaft.
Gear drive is made up of input shaft, tween drive shaft, output shaft and gear, and input shaft, tween drive shaft, output shaft and gear cluster are contained on the body.
Electrical motor rotates input shaft during work, female gear moves axially presses to ratchet, ratchet is pressed to friction disc by friction lining, and pressure is tight more more, and under the friction force effect, friction disc rotates by friction lining ratchet driven gear, this moment, ratchet and ratchet broke away from, power drives output shaft and rotates synchronously by gear drive, and output shaft can drive load work.When load need aloft stop, turn off power supply, the input shaft stall, load forces the gear counter-rotating by transmissions such as output shafts, moves and presses to ratchet, and gear, ratchet, friction lining, friction disc frictionally are bound up, when ratchet reverses, ratchet sticks ratchet immediately and self-locking has stoped the counter-rotating of driving system, has reached the aerial purpose that stops of load.When load need descend, the input shaft counter-rotating, gear leaves ratchet, but because the antagonistic force of load makes gear near ratchet again, because of results of interaction, the friction force of ratchet both sides is inoperative all the time, brake disc and gear rotate, and ratchet is still blocked by ratchet and do not change.When load need aloft stop, produce self-locking again immediately as long as turn off power supply, load can aloft stop.When the unloaded lotus of needs descends fast, can make power-transfer clutch work by handle, lose the ability of transferring power between gear and the output shaft, output shaft can reverse separately under the effect of unloaded lotus (still needing certain counterweight) fast, unloaded lotus is descended fast, not only improved effect, also saved the energy.After arriving assigned address, make power-transfer clutch recover bonding state by handle, actuating motor continues to finish and descends or lifting work.
Its beneficial effect is: the utility model is provided with self-locking device in gear drive; Mechanical efficiency is up to 98%.
Be characterized in: the utility model compact conformation, reasonable in design, easy to manufacture, with low cost, energy efficiency, operating maintenance are convenient, safe and reliable, and range of use is wide.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model, among the figure 1, and ratchet; 2, ratchet; 3, gear; 4, friction lining; 5, gear; 6, gear; 7, output shaft; 8, gear; 9, handle; 10, power-transfer clutch; 11, bearing; 12, tween drive shaft; 13, body; 14, input shaft; 15, friction disc.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.(as lifting) electrical motor rotates input shaft 14 during work, female gear 3 at first moves axially presses to ratchet 2, ratchet 2 is pressed to friction disc 15 by friction lining 4, and pressure is tight more more, under the friction force effect, friction disc 15 rotates by friction lining 4 ratchets 2 driven gears 3, this moment, ratchet 1 broke away from ratchet 2, and power rotates gear 8 by gear 5, gear 6, because the combination of power-transfer clutch, output shaft 7 rotates synchronously with gear 8, and output shaft 7 can drive load work.When load need aloft stop, turn off power supply, input shaft 14 stalls, load forces gear 3 counter-rotatings by output shaft 7 transmissions such as grade, moves and presses to ratchet 2, and gear 3 ratchets 2 friction linings 4 friction discs 15 frictionallies are bound up, when ratchet 2 counter-rotatings, ratchet 1 sticks ratchet 2 immediately and self-locking has stoped the counter-rotating of driving system, has reached the aerial purpose that stops of load.When load need descend, input shaft 14 counter-rotatings, gear 3 leaves ratchet 2, but because the antagonistic force of load makes gear 3 near ratchet 2 again, because of results of interaction, the friction force of ratchet 2 both sides is inoperative all the time, brake disc 15 and gear 3 rotates, and ratchet 2 is still blocked by ratchet 1 and do not change.When load need aloft stop, produce self-locking again immediately as long as turn off power supply, load can aloft stop.When the unloaded lotus of needs descends fast, can make power-transfer clutch 10 work by handle 9, lose the ability of transferring power between gear 8 and the output shaft 7, output shaft 7 can reverse separately under the effect of unloaded lotus (still needing certain counterweight) fast, unloaded lotus is descended fast, not only improve effect, also saved the energy.After arriving assigned address, make power-transfer clutch 10 recover bonding state with gear 8 by handle 9, actuating motor continues to finish and descends or lifting work.
