Abstract
Abstract A milling roller mounting support on milling machines for milling road surfaces has a frame vertically adjustable and at right angles relative to the direction of movement provided on the chassis. The milling roller is rotatably supported at its ends in the frame and is driven on one, or both, respectively, sides by means of a motor each. The frame is provided between at least two parallel guide faces arranged one after the other in the direction of movement and is secured to the chassis by two mounting supports, which are vertically adjustable. A lateral shift of the frame is avoided by a nose arranged at right angles relative to the axis of the milling roller, which nose is guided in a vertical groove provided in the chassis.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
A milling roller mounting support for milling machines used for milling road surfaces, said milling roller having an axis and spaced opposite axial ends and said mounting support comprising a chassis having two substantially parallel guide surfaces located behind each other in the direction of movement, said chassis having a substantially vertical groove formed in a surface thereof; a pair of vertically adjustable supports mounted on said chassis; and a frame positioned at substantially right angles to the direction of movement and supported in said chassis by said supports in a manner whereby said frame is guided by said guide surfaces, wherein said milling roller is tiltingly supportable at its end via said supports, said frame having a nose extending substantially at right angles to the axis of said milling roller and extending into said groove of said chassis for guiding said frame.
Claim 2
Dependent Claim
143 words
A milling roller mounting support for milling machines used for milling road surfaces, said milling roller having an axis and spaced opposite axial ends and said mounting support comprising a chassis having two substantially parallel guide surfaces located behind each other in the direction of movement, said chassis having a substantially vertical groove formed in a surface thereof; a pair of vertically adjustable supports mounted on said chassis; and a frame positioned at substantially right angles to the direction of movement and supported in said chassis by said supports in a manner whereby said frame is guided by said guide surfaces, wherein said milling roller is tiltingly supportable at its end via said supports, said frame having a nose extending substantially at right angles to the axis of said milling roller and extending into said groove of said chassis for guiding said frame.
Claim 3
Dependent Claim
28 words
A milling roller mounting support as claimed in claim 1, wherein said nose and said groove are positioned substantially midway between said axial ends of said milling roller.
Claim 4
Dependent Claim
35 words
A milling roller mounting support as claimed in claim 1, wherein said guide faces are positioned near said axial ends of said milling roller and said groove is formed in one of said guide faces.
Claim 5
Dependent Claim
18 words
A milling roller mounting support as claimed in claim 1, wherein said nose has a substantially circular cross-section.
Claim 6
Dependent Claim
30 words
A milling roller mounting support as claimed in claim 1, further comprising a slide block slidably mounted in said groove and wherein said nose is supported in said slide block.
Claim 7
Dependent Claim
20 words
A milling roller mounting support as claimed in claim 1, wherein said supports comprise hydraulic lifting cylinders for said frame.
Claim 8
Dependent Claim
19 words
A milling roller mounting support as claimed in claim 1, wherein said supports comprise winding screws for said chassis.
Claim 9
Dependent Claim
16 words
A milling roller mounting support as claimed in claim 7, wherein said winding screws are motor-actuated.
