Abstract
The utility model uses the worm and wormwheel gear reducer of planar second envelope in a concrete stirring shaft drive device. The worm and a motor output shaft is driven through a belt pulley, and a wormwheel shaft hole and a stirring shaft is fitted in the spline fit mode. The utility model is used for symmetrically arranging a motor and the gear reducer in double-horizontal-shaft time. The gear reducer is used a synchronization mechanism through a yielding coupling. The utility model has the advantages of high drive efficiency, a durable and reliable synchronization mechanism, an overload protection function, small volume of the complete machine, light weight and a large capacity.
Description
The utility model is relevant with transmission device, and is especially relevant with the twice-enveloping Worm and Worm Gear Driving device of concrete mixer stirring shaft.Traditional single, double horizontal axis concrete mixer stirs shaft drive and uses planetary cycloidal pin gear reducer.Retarder directly links to each other with motor output shaft on (dual horizontal axle) or by belt pulley link to each other with motor output shaft (single horizontal axis).Reducer output shaft drives stirring shaft work by gear or coupling.There are cylindrical gears lazy-tongs (dual horizontal axle) that the angular velocity of two stirring shafts is equated on the stirring shaft.Though it is shock-resistant that this transmission device has, the characteristics that overload capacity is big, there have following shortcoming to hinder stirrer to be little towards volume, and capacity is big, quality of product high aspect development:
One, stirring shaft load condition complexity, work under bad environment, when stuck phenomenon appearred in stirring shaft, whole transmission device did not have overload protection function, certainly will cause great mechanical accident.
When two, being used for double-horizontal axle concrete-mixer,, adopt exposed gear as lazy-tongs because the output angle speed of two retarders is actually discrepant.Work under the stirrer rugged environment, exposed gear very easily weares and teares, and reduces intensity and working life.The serviceability and the reliability of lazy-tongs are lower.
Three, reducer output shaft is connected by coupling or gear with stirring shaft, strengthens the physical dimension and the weight of transmission device.
The purpose of this utility model is to improve transmission efficiency, the Transmission bearing that concrete stirs shaft drive, reduces the physical dimension and the quality of transmission device, increases the reliability and the serviceability of lazy-tongs, increases the overload protective function of device.
The purpose of this utility model is achieved in that
The utility model is by retarder, motor, and driving mechanism is formed, and retarder is the twice-enveloping worm gear reducer, and worm screw links to each other with motor output shaft by pulley transmission mechanism.Worm-wheel shaft has spline to cooperate with stirring shaft.
The utility model can be by two cover motors, the twice-enveloping worm gear reducer, and the pulley transmission mechanism symmetric arrangement is formed.The worm screw of two retarders is connect by elastic coupling flexible coupling.The output shaft of three retarders is that worm-wheel shaft is connected with two stirring shafts respectively.
The utility model retarder transmission efficiency height, bearing capacity is big, is used for big capacity concrete mixer and sink need be set.The transmission efficiency of twice-enveloping worm gear reducer is higher by 30% than Archimedes Worm and Worm Wheel, and bearing capacity than its high 2.3-4.3 doubly.Transmission efficiency is higher by 10% than hourglass screw worm gear, and the transmission efficiency of complete machine can be greater than 0.82.Specific volume is little by about 50%, in light weight 60% mutually with the retarder of equal-wattage and speed ratio.
The utility model uses the belt pulley transmission, has overload protection function.When being used for twin-shaft mixer, adopt symmetric arrangement, elastic coupling flexible coupling connects, and does not need complexity, but expensive starting arrangement is with regard to actuating motor; Lazy-tongs are reliable, and are durable.
The utility model reducer output shaft directly cooperates with stirring shaft by spline, compact integral structure, and volume is little, and is in light weight, beautiful shape.
In sum, the utility model.The planar quadratic and annular enveloping worm worm speed reducer is applied to concrete stirs shaft drive, overcome stirrer to reducing volume, the increase capacity improves the obstacle of serviceability and Economy aspect development, has obvious improvement.

Following is embodiment of the present utility model:
Embodiment 1:
The utility model is used for the transmission of twin-shaft mixer stirring shaft.By two cover big belt pulleys 25, small belt pulley 27, V belt 26, motor 28, twice-enveloping worm gear reducer 22,24 symmetric arrangement are formed.The worm screw 30 of retarder 22,24 is connect by elastic coupling flexible coupling 23, and the axle of worm gear 31 has spline to cooperate with stirring shaft 29.During work, the motor drives belt transmission is slowed down by the twice-enveloping worm type of reduction gearing.Owing to two retarders and drive motor symmetric arrangement, the sense of rotation of two worm screws is consistent, by the angular velocity unanimity of coupling 23, two worm screws.Worm-wheel shaft drives stirring shaft by spline and rotates synchronously.Because use two motors 28, starting current is little, do not need complicated starting arrangement.Because adopt V belt and coupling, complete machine has overload protection function, and lazy-tongs are reliable, durable.Because twice-enveloping worm gear reducer transmission efficiency height does not need to add in addition sink.
Embodiment 2:
The utility model is used for the transmission of single horizontal axis stirrer.
