Description
Technical field
The utility model relates to engineering machinery, relates in particular to the milling rotor on the milling machine that uses in a kind of pavement construction.
Background technology
The milling machine that prior art is used in asphalt pavement construction, there is following defective usually in its milling rotor when assembling and dismounting maintenance: the one, and the milling cylinder is difficult especially when assembling, and under the situation that the milling rotor does not install fully, other parts can not assemble, and production efficiency is low.The 2nd, milling machine in use often need be changed the milling rotor, and the milling rotor is all relatively more difficult when assembling and dismounting, and complicated operation is consuming time many, influences construction speed.The 3rd, milling rotor structure complexity, unstable properties, requirement on machining accuracy height.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, is easy to processing and fabricating, convenient for assembly and dismounting maintenance, thereby the milling rotor on the pavement milling machine that can increase work efficiency.
The purpose of this utility model can realize by following technical measures
Milling rotor on this pavement milling machine, outside the milling cylinder, be connected with the milling tool magazine that several are equipped with the milling cutter head, be connected with left fixed head and right fixed head in the milling cylinder two ends respectively, connect in the spline housing of left fixed head splined shaft is arranged, the other end of splined shaft is connected with drive, establish the power transmission shaft bearing of bearing in having outside the middle part of splined shaft, the right side of right fixed head is connected with supporting bearing base, and an end that supports spindle nose has bearing outward and is positioned at the supporting bearing base inboard.
The purpose of this utility model also can realize by following technical measures
Between spline housing and power transmission shaft bearing the seal cover that is connected the power transmission shaft bearing is arranged, there are oil sealing and sealing felt collar in the seal cover inboard, and supporting bearing base is connected with outward and is positioned at the bearing gland that supports the spindle nose outside, and there are oil sealing and sealing felt collar in the supporting bearing base inboard.
The utility model is simple in structure, is easy to processing and fabricating, and convenient for assembly and dismounting maintenance has improved production efficiency greatly.Compared with prior art, the first, after finishing, the transmission shaft component assembling can carry out the installation of other each parts, do not influence final assembly.The second, simple when milling cylinder and power transmission shaft assembling, can change the milling cylinder according to construction requirement during work in good time, quick and convenient.The 3rd, the milling cylinder is a monolithic construction, and processing is simple, and the precision precise control is suitable for producing in enormous quantities.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The milling cylinder 20 outer material casting plates 21 that are connected with are equipped with the milling tool magazine 11 of milling cutter head 12 with several, be connected with left fixed head 23 and right fixed head 22 in milling cylinder 20 two ends respectively, connect in the spline housing 10 of left fixed head 23 splined shaft 3 is arranged, the other end of splined shaft 3 is connected with drive 2, establish the power transmission shaft bearing 5 of bearing 7 in having outside the middle part of splined shaft 3, there is oil baffle disc 6 inboard of bearing 7, spline housing 10 has the seal cover 24 that is connected power transmission shaft bearing 5 with 5 of power transmission shaft bearings, there are oil sealing 8 and sealing felt collar 9 in seal cover 24 inboards, be positioned at the power transmission shaft bearing 5 outer left plates 4 that are connected with of milling cylinder 20 left-external sides, the adjustment dish 1 that connects splined shaft 3 left ends joins with drive 2.The right side of right fixed head 22 is connected with supporting bearing base 15, an end that supports spindle nose 13 has bearing 16 outward and is positioned at supporting bearing base 15 inboards, supporting bearing base 15 outer being connected with are positioned at the bearing gland 17 that supports spindle nose 13 outsides, there are oil sealing 18 and sealing felt collar 19 in supporting bearing base 15 inboards, and right plate 14 is connected and fixed by supporting bearing base 15 and right fixed head 22.
When using operation, power passes to drive 2 by chain, passes to spline housing 10 by splined shaft 3 again, and spline housing 10 drives milling cylinder 20 rotary works.Right side supporting bearing base 15 to right fixed head 22, limits the axial freedom of milling cylinder 20 by screw.When need are changed the milling rotor fast, the Hydraulic trolley yoke extend into slowly to be raised up to below the milling cylinder 20 stop when feeling moment, unclamp the attachment screw of right plate 14 and supporting bearing base 15 and right fixed head 22 with spanner, with jackscrew the right plate 14 and the alignment pin of right fixed head 22 are thrown off again, the pulling Hydraulic trolley can be deviate from milling cylinder 20 integral body, can change milling cylinder 20.During assembling in contrast.
