The utility model relates to a kind of speed reducer, specifically is a kind of cement roll-in speed reducer.
Background technique
The speed reducer of cement plant use at present has various, and TMV87, TMV130 are arranged, and MBG20,22 also has RPG series as RPG23,24,26,29,30,32.RPG series planetary reduction box is the output maximum at present, most widely used cement speed reducer.The RPG35 speed reducer is present volume maximum, and velocity ratio is the highest, transmitting torque and most effective.At present, other serial output shaft of RPG and planet carrier all are separate machined, complex procedures not only, and add and cause each axis hole and axle journal decentraction man-hour easily.
The model utility content
The purpose of this utility model is to address the above problem, and a kind of bearing hole coaxality, perpendicularity height are provided, the cement roll-in speed reducer that output shaft and planet carrier are concentric.
For reaching the foregoing invention purpose, the technological scheme that is adopted is: a kind of cement roll-in speed reducer, described speed reducer is mainly by casing and place the transmission device in the casing to connect and compose, wherein said casing is by first box assembly, second box assembly, the 3rd box assembly and four box assemblies of the 4th box assembly are interconnected to constitute successively, described transmission device comprises the planetoid frame, big sun gear, the output shaft planet carrier, planet wheel, small sun gear, input driven axle and input shaft, the described big sun gear that is installed in the casing, small sun gear, the axle center of input driven axle and two bearing holes of output shaft planet carrier is on same axis.
Described input shaft penetrates into the holding cavity that is connected and composed by first box assembly and second box assembly from the upper end tank wall of first box assembly, and the gear of the input driven axle that the gear on the input shaft is interior with being arranged at this holding cavity is meshed.
Described planetoid frame and the holding cavity that places the small sun gear on the planetoid frame to place second box assembly and the 3rd box assembly to connect and compose jointly, the internal tooth of input driven axle lower end and the engagement of the crowned teeth on the small sun gear wheel shaft, the straight-tooth part of small sun gear meshes with planetoid frame planet wheel.The planet wheel of described planetoid frame also is engaged with little gear ring.
Described output shaft planet carrier and the holding cavity that places the 3rd box assembly and the 4th box assembly to connect and compose jointly as for the big sun gear in this output shaft planet carrier, the internal tooth of planetoid frame bottom is meshed with the crowned teeth of big sun gear, and the straight-tooth of big sun gear is meshed with output shaft planet carrier planet wheel.Also be engaged with bull gear on the planet wheel of described output shaft planet carrier.
Gap location between described small sun gear and planetoid frame and big sun gear and the output shaft planet carrier also is provided with nylon block and jacking block.
Working principle of the present utility model is: the driven by motor input shaft rotates, input shaft cogs and imports the driven shaft gear engagement, produce velocity ratio, input driven axle and small sun gear engagement rely on the crowned teeth engagement on input driven shaft gear lower end internal tooth and the small sun gear wheel shaft, will import the driven axle rotating speed and be delivered on the small sun gear.The small sun gear straight-tooth partly meshes with planetoid frame planet wheel, planetoid frame planet wheel meshes with little gear ring internal tooth again, therefore the planetoid frame floats in casing, generation is than the big retarding ratio, the planetoid frame rotates the internal tooth and the crowned teeth engagement of sun gear greatly that relies on its underpart, and planetoid frame rotating speed is delivered to big sun gear.Equally, big sun gear is again by straight-tooth and the engagement of output shaft planet carrier planet wheel, output shaft planet carrier planet wheel is meshed with the internal tooth of bull gear again, produce big velocity ratio once more, the highest rotating speed of motor reduces to lower rotating speed and is transported on the cement roll squeezer by output shaft, makes the cement roll squeezer obtain lower rotating speed and obtains bigger moment of torsion.
In sum, the utility model is simple and reasonable, and speed reducer mainly comprises input, output link, is provided with the two-stage planet carrier and slows down between input, output, thereby reach the velocity ratio height, the requirement that output torque is big.This speed reducer turns round steadily, is as good as sound, ne-leakage, output power maximum, output torque maximum, input speed height, and each bearing hole coaxality, perpendicularity require high.
