Abstract
The utility model discloses a transmission device of an arm-support rotating platform of a concrete pump truck, comprising a speed reducer, a transmission gear and the arm-support rotating platform. The transmission device is characterized in that only one speed reducer is arranged for finishing rotation of the arm-support rotating platform; a transmission chain is in such a structure: the speed reducer is connected with a driving gear, the two sides of the main driving gears are respectively provided with a meshing duplex gear, and the arm-support rotating platform is driven to rotate by the two meshing duplex gears. The transmission chain of the speed reducer and the arm-support rotating platform is a speed reducing chain; primary speed reduction is realized by the driving gear on a speed reducer shaft and the two duplex gears, and the speed ratio is 2-3:1; and secondary speed reduction is realized by the two duplex gears and the arm-support rotating platform, and the speed ratio is 30-100:1. For the speed reducer, the rated power is 10.5KW, the rated torque is 3.11*10<4>N.m, and the rated rotating speed is 3.2r/min. The transmission device has the advantages that the processing is simple, the operating performance is stable, the structure is compact, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of jib turntable transmission device of concrete mixer, particularly discloses a kind of jib turntable transmission device that has the concrete mixer of duplicate gear transmission, is applied to technical field of engineering machinery.
Background technique
The jib of concrete mixer is made up of single oil cylinder, when pump concrete, need launch jib and realize the jib turntable ± 365 ° of rotations.In order to realize this ± 365 ° of pumpings, so adopt gear and speed reducer to realize rotation.
Existing pumping vehicle arm rack turntable whirligig adopts both sides that speed reducer and driving gear all are installed, and structure such as Fig. 1 are employed in the turntable both sides and a speed reducer (comprising driving gear) respectively is installed is come carry-over moment, realize the rotation of turntable.
Existing both sides all have the turntable of speed reducer in mach process, must need bigger process equipment of machining range and more workman to accomplish the processing of both sides speed reducer mounting plate man-hour.Simultaneously, when adopting two speed reducer runnings, the transferred pressure signal has certain delay to the driving of the speed reducer of both sides in the hydraulic system, has guaranteed not absolute synchronous drive; And the moment that is produced also can influence each other, and finally can influence the normal transmission of gear, influences the working life of gear.Adopt two speed reducers not only to increase the complete machine cost simultaneously, it all brings very big inconvenience in assembling, maintenance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that needs two speed reducer carry-over moments of utilization in the existing technology, discloses a kind of jib turntable transmission device of concrete mixer, adopts a speed reducer to realize transmission with two duplicate gear ways of connecting simultaneously.
The utility model is achieved in that a kind of concrete pump truck arm turntable transmission device; Comprise speed reducer, driving gear and jib turntable; It is characterized in that: described concrete pump truck arm turntable transmission device is only established a speed reducer and is accomplished the rotation of jib turntable; Its Transmitted chains is: speed reducer connects driving gear, and respectively there is an engagement duplicate gear driving gear both sides, again by two duplicate gear transmission jib turntable rotations.The Transmitted chains of described speed reducer transmission jib turntable is a rough lock, and the driving gear on the deceleration arbor and two duplicate gears are realized once slowing down, and speed ratio is 2～3:1, realizes secondary speed-reducing by two duplicate gears and jib turntable again, and speed ratio is 30～100:1.The rated power of said speed reducer is 10.5 kilowatts, rated torque 3.11 * 10
4Ox rice, rated speed are 3.2 rev/mins.
Form speed reducer by two duplicate gears, driving gear, speed reducers.Driving gear is installed between two duplicate gears, and its effect is to carry out transmission of torque, and the moment that speed reducer provided is delivered to two duplicate gears through driving gear, can drive two duplicate gears simultaneously and rotate in the same way.Realize the rotation of turntable through the rotation in the same way of two duplicate gears.
The beneficial effect of the utility model is: the utility model ride quality is stable; Duplicate gear transmission functional reliability is high; Compact structure can guarantee that constant transmission recently carries out transmission, can let turntable steadily rotate simultaneously; Reduce noise and reduced gear wear, the working life of having improved equipment widely.The utlity model has advantages such as processing is simple, cost is low, maintenance is convenient, can fully meet customer need.

Embodiment
According to accompanying drawing 2 and 3, a kind of concrete pump truck arm turntable of the utility model transmission device comprises speed reducer, driving gear and jib turntable.Concrete pump truck arm turntable transmission device is only established a speed reducer 6 and is accomplished 5 rotations of jib turntable.Its Transmitted chains is: speed reducer 6 connects driving gear 3, and respectively there is an engagement duplicate gear driving gear 3 both sides, are first duplicate gear 2 and second duplicate gear 4, again by 5 rotations of two duplicate gear transmission jib turntables.The Transmitted chains of speed reducer 6 transmission jib turntables 5 is a rough lock, and the driving gear 3 on 6 of the speed reducers and two duplicate gears are realized once slowing down, and speed ratio is 2～3:1, and by two duplicate gears and jib turntable 5 realization secondary speed-reducings, speed ratio is 30～100:1 again.The rated power of speed reducer 6 is 10.5 kilowatts, rated torque 3.11 * 10
4Ox rice, rated speed are 3.2 rev/mins.
The driving gear of speed reducer and two duplicate gear ride qualities are stable, and duplicate gear transmission functional reliability is high, compact structure; Guarantee that constant transmission recently carries out transmission; Simultaneously can let turntable steadily rotate, reduce noise and reduced gear wear, the working life of having improved equipment widely.
