Go out end, and rotated by chain drive driven sprocket, driven sprocket drives the rotation of milling wheel reductor, milling wheel reductor output torque
Milling wheel rotary work is driven by shock ring；The driven sprocket is fixedly mounted on transmission case by the bearing of both sides, bearing block
On support base below body, seal receptacle and sealing are separately installed with the outside of bearing block, are sealed cylindrical with driven sprocket output shaft
Face coordinate realize sealing, so as to transmission case body inner space be isolated with both sides milling wheel reductor inner space, formation every
From the independent sealed space of formula.
Preferably, the fixing end of the milling wheel reductor is mounted on support base, is installed end face and is designed with static seal；
Milling wheel output end of reducer is rotated against with milling wheel reductor fixing end, and sealing is designed between the two, can be by milling wheel reductor
Inner space keeps apart with extraneous mud, is effectively sealed.
Preferably, the actuating unit includes motor and reductor, and reductor is arranged on the outfan of motor, reductor
Outfan is connected with drive sprocket.
Compared with prior art, this utility model will be passed by designing rotary, can be pressure sealing with sealing holder structure
Dynamic case is kept apart with both sides milling wheel so that each milling wheel space independence, and is not communicated with transmission case inner space.If its
In there is oil leak at a milling wheel or enter mud problems, will not affect that bearing, gear in transmission case and opposite side milling wheel etc.
Part, greatly reduces maintenance cost.Meanwhile, can be designed with milling wheel reductor fixing end and support base installation end quiet close
Envelope, between milling wheel output end of reducer and milling wheel reductor fixing end sealing is designed with, by milling wheel reductor inner space and
Extraneous mud is effectively kept apart, and effectively prevents extraneous mud to enter in milling wheel reductor, and prevents milling wheel reductor
There is leakage in interior gear oil.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
As shown in Figures 1 to 4, a kind of isolated two-wheel flute milling machine transmission case, including transmission case body 1, actuating unit 2, master
Movable sprocket 3, driven sprocket 5, support base 6, milling wheel reductor 7, milling wheel 9, bearing block 11, bearing 12 and it is rotary, can be pressure
Sealing 13 and seal receptacle 14, actuating unit 2 is fastened in transmission case body 1；Drive sprocket 3 is arranged on actuating unit 2
Outfan, and drive driven sprocket 5 to rotate by chain 4, driven sprocket 5 drives milling wheel reductor 7 to rotate, milling wheel reductor 7
Output torque drives the rotary work of milling wheel 9 by shock ring 8；The driven sprocket 5 is consolidated by the bearing 12 of both sides, bearing block 11
Dingan County is mounted on the support base 6 of the lower section of transmission case body 1, and in the outside of bearing block 11 seal receptacle 14 and sealing 13 are separately installed with, close
Envelope 13 coordinates with the output shaft periphery of driven sprocket 5 realizes sealing, so as to the inner space of transmission case body 1 and both sides milling wheel be slowed down
The inner space of machine 7 is isolated, and forms isolated independent sealed space.As shown in Figures 1 to 4, support base 6 has two, actively
Sprocket wheel 3, driven sprocket 5 have two sets, often cover each to two milling wheels 9 of both sides driving, that is, have four milling wheels, and four milling wheels slow down
Machine.
As shown in Figure 3 and Figure 4, in order that the inner space of milling wheel reductor 7 forms effectively sealing with outside mud, can be ingenious
Utilization milling wheel speed reducer structure and the mounting means between support base, by milling wheel reductor inner space respectively with the external world
Mud, transmission case body are kept apart, and are carried out independent sealed.Such as the fixing end of the milling wheel reductor 7 can be mounted on and be propped up
On support seat 6, end face is installed and is designed with static seal；The outfan of milling wheel reductor 7 is rotated against with the fixing end of milling wheel reductor 7, and two
Sealing 10 is designed between person, the inner space of milling wheel reductor 7 can be kept apart with extraneous mud, effectively sealed.
Preferably, the actuating unit 2 includes motor and reductor, and reductor is arranged on the outfan of motor, reductor
Outfan be connected with drive sprocket 3.
Using front, motor, reductor and drive sprocket 3 can be fixedly mounted in transmission case body 1, drive sprocket 3 is pacified
It is mounted in the outfan of reductor；Meanwhile, aforementioned manner is installed driven sprocket 5 and milling wheel reductor 7 are arranged in milling wheel 9, it is main
Connected by chain 4 between movable sprocket 3 and driven sprocket 5.
During work, because rotary, can be pressure sealing can isolate transmission case body with both sides milling wheel with sealing holder structure
Come so that each milling wheel space independence, and be not communicated with transmission case inner space.If occurring leakage at one of milling wheel
Oil enters mud problems, will not affect that the part such as transmission case and bearing, the gear in opposite side milling wheel, greatly reduces maintenance
Cost.Meanwhile, end can be installed in milling wheel reductor fixing end and support base and be designed with static seal, in the output of milling wheel reductor
Sealing is designed between end and milling wheel reductor fixing end, milling wheel reductor inner space is effectively isolated with extraneous mud
Open, effectively prevent extraneous mud to enter in milling wheel reductor, and prevent the gear oil in milling wheel reductor leakage occur.
