Background technology
In the present all kinds of reductor, under the identical situation of output torque, desire will strengthen reduction ratio, then the volume of casing must strengthen, the whole volume that is reductor will increase, and work is not steady, and vibration and noise are bigger, increase in temperature, its service life is shorter, and the classification of transmitting ratio is big at interval, simultaneously owing to be subjected to the restriction of installation form, the user can only be provided a kind of lower margin mounting means, can not satisfy the demand of the multiple installation pattern of user.The reductor that generally uses in bont is generally worm reduction gear, and there is the use defective that power is big, energy consumption is high in worm reduction gear.
The utility model content
Technical problem to be solved in the utility model provides a kind of compact conformation, uses the little gig drop-gear box of power.
The utility model solves the problems of the technologies described above with following technical scheme: three arrangement in parallels deceleration transmission axle in one plane is installed in the casing 7 of the utility model gig drop-gear box, article one one-level deceleration hinge wheel 21 and one-level reduction pinion teeth 6 are installed on the deceleration transmission axle 5, double reduction miniature gears 10 and double reduction big gear wheel 9 are installed on the second deceleration transmission axle 11, article three, on the deceleration transmission axle 14 three grades of deceleration big gear wheels 15 are installed, one-level deceleration hinge wheel 21 is connected by chain 4 with sprocket wheel 3 on the motor output shaft 2, one-level reduction pinion teeth 6 is meshed with double reduction big gear wheel 9, double reduction miniature gears 10 is meshed with three grades of deceleration big gear wheels 15, and the 3rd deceleration transmission axle 14 stretches out the cylinder 18 that hand brake device and cover are useful on folding and unfolding rope rope is installed on the axle in the casing outside.
Gear on described three deceleration transmission axles can be a cylindric spiral gear.
Described hand brake device can be made of brake wheel 16, brake rubber block 20 and hand brake lever 17, and brake wheel 16 is installed on the 3rd the deceleration transmission axle 14, and brake rubber block 20 is installed on the frame 22, and hand brake lever 17 is connected with brake rubber block 20.
The utility model gig drop-gear box adopts tertiary gear to slow down, and uses power little, and consumption of current is low, uses 180 watts of motors, just can promote 100 kilograms goods, and maximum can reach 180 kilograms, is particularly suitable for small and medium construction and promotes the goods use.
Description of drawings
Fig. 1 is the structural representation of the utility model gig drop-gear box.
Fig. 2 is that scheme drawing is looked on the left side of Fig. 1.
Among the figure: motor 1, motor output shaft 2, sprocket wheel 3, chain 4, article one deceleration transmission axle 5, one-level reduction pinion teeth 6, casing 7, one-level bearing 8, double reduction big gear wheel 9, double reduction miniature gears 10, second deceleration transmission axle 11, secondary bearing 12, three grades of bearings 13, the 3rd deceleration transmission axle 14, three grades of deceleration big gear wheels 15, brake wheel 16, hand brake lever 17, cylinder 18, bearing 19, brake rubber block 20, one-level deceleration hinge wheel 21, frame 22.
The specific embodiment
As depicted in figs. 1 and 2, three arrangement in parallels deceleration transmission axle is in one plane arranged in the casing 7 of the utility model gig drop-gear box, article one, deceleration transmission axle 5 is installed on the casing 7 by the one-level bearing 8 of both sides, on its axle one-level deceleration hinge wheel 21 and one-level reduction pinion teeth 6 are installed, second deceleration transmission axle 11 is installed on the casing 7 by the secondary bearing 12 of both sides, on its axle double reduction miniature gears 10 and double reduction big gear wheel 9 are installed, article three, deceleration transmission axle 14 is installed on the casing 7 by three grades of bearings 13 of both sides, on its axle three grades of deceleration big gear wheels 15 are installed, one-level deceleration hinge wheel 21 is connected by chain 4 with sprocket wheel 3 on the motor output shaft 2, one-level reduction pinion teeth 6 is meshed with double reduction big gear wheel 9, double reduction miniature gears 10 is meshed with three grades of deceleration big gear wheels 15, article three, deceleration transmission axle 14 axle that stretches out the casing outside is gone up and outwards hand brake device is installed successively and is set with cylinder 18 and the bearing 19 that is used for folding and unfolding rope rope, and bearing 19 is installed on the frame 22; Hand brake device is to be made of brake wheel 16, brake rubber block 20 and hand brake lever 17, and brake wheel 16 is installed on the 3rd the deceleration transmission axle 14, and brake rubber block 20 is installed on the frame 22, and hand brake lever 17 is connected with brake rubber block 20.
During work, starter motor 1, driving one-level deceleration hinge wheel 21 by the sprocket wheel on the motor output shaft 23 through chain 4 rotates, finish the first order deceleration task this moment, rotate and drive the double reduction big gear wheel 9 that is meshed with the coaxial one-level reduction pinion teeth 6 of one-level deceleration hinge wheel 21, finish the second stage deceleration task this moment, rotates and drive the three grades of deceleration big gear wheels 15 that are meshed with the coaxial double reduction miniature gears 10 of double reduction big gear wheel 9, finishes the third stage deceleration task this moment.After three grades of decelerations, drive cylinders 18 by the power of motor 1 output and rotate, twine the rope rope that is used to promote goods on the cylinder 18, and the operation of folding and unfolding rope rope can transfer realization by control motor positive and negative by the 3rd deceleration transmission axle 14.When in lifting process, needing shut-down operation, the hand brake lever of hand brake device is pressed down, make brake rubber block compress brake wheel, cylinder 18 just is in halted state, thereby realizes that the goods that is promoted all can stop at arbitrary height.
