Description
Technical field
The utility model is related to a kind of two-wheel flute milling machine transmission case, for the two-wheel groove milling of continuous wall trench underground construction
Machine, belongs to two-wheel flute milling machine technical field.
Background technology
At present, continuous wall trench underground construction two-wheel flute milling machine is that power of getting on the bus is transferred to milling wheel by transmission case,
Milling wheel rotation is driven, the purpose of milling broken formation is reached.Two-wheel flute milling machine adapts to stratum extensively, especially constructs in ground consisting of hard rock,
Its efficiency of construction and economy can more be highlighted.In the course of work, transmission case had both transmitted the power of milling rock stratum；Support milling is played again
Wheel is acted on, and bears larger radial load and impact shock.Therefore, transmission case must possess following performance：
1st, can transmitting large torque, to tackle hard rock construction；
2nd, support the thickness of milling wheel support base the smaller the better in the case where strength conditions are met, because thickness is too big, two side millings
In the middle of wheel cannot milling blind area it is accordingly larger, transmission case can be caused " to sit on the fence " phenomenon, lead to not construction；
3rd, radial load can be transferred on transmission case body by internal structure itself, so as to mitigate the footpath of transmission revolving part
To load；
4th, while transmission case rotary work, sealing property is reliable, to prevent transmission case in oil leak or the external world
Mud enters transmission case, causes driving member to fail；
5th, transmission case indoor design has shock-absorbing function, can by milling wheel milling rock stratum when the impact shock that is subject to absorbed
Buffering, reduces impact shock to each driving member in transmission case inside, the infringement of sealing property, improves transmission case reliability and work longevity
Life.
Existing continuous wall trench underground construction two-wheel flute milling machine is with the precious high two-wheel groove milling of import Germany on domestic market
Based on machine, the user of minority uses repacking simple type two-wheel flute milling machine.
The transmission case of precious high two-wheel flute milling machine can transmitting large torque, compact conformation, support base thickness it is little, but its internal drive
Complex structure, detachable maintaining difficulty are big.Its operation principle is to drive power transmission shaft, power transmission shaft to change by bevel gear again using motor
To, drive reductor, reductor is connected with sprocket wheel, so as to drive milling wheel rotary work.

A kind of two-wheel flute milling machine (the application number of invention disclosed patent on the 15th：200810028551.3), the driving means include passing through
The slow-speed of revolution of the oil bath lubrication sealing device in seal case, high-torque hydraulic motor and by being installed on the hydraulic motor output shaft
On minor sprocket, for drive milling wheel rotate big sprocket wheel and connection minor sprocket, big sprocket wheel chain composition gear machine
Structure.In actual use, there are the following problems：Firstth, the variable transmission mechanism is finally transmitted to moment of torsion on milling wheel etc.
In the moment of torsion of big sprocket wheel, but because support base thickness is limited, therefore chain specification used is limited, so as to the torsion that chain bears
Square is less, causes the operation torque for being finally transmitted to milling wheel less.If selecting big specification chain, support base thickness meeting
It is very big, it may appear that " sitting on the fence " phenomenon and cannot construct.Secondth, the milling cutter wheel and rotating wheel, rotating wheel of the variable transmission mechanism with
Big sprocket wheel whole rigidity connects, and in work progress, the radial load that milling cutter wheel is subject to all is passed with shock loading by rotating wheel
Big sprocket wheel is handed to, reliability and life-span of each driving member with seal in whole transmission system is greatly reduced.
