Abstract
A milling cutter for truing railroad wheels has a milling drive shaft (10) with at least two, preferably three, cutter sections (3, 4, 5). One fixed cutter section (4) is rigidly connected to the shaft (10). At least one, preferably two, cutter sections (3, 5) are axially shiftable along the shaft (10) and receive their torque drive through the fixed cutter section through a releasable coupling such as a claw clutch (9, 30). One axially shiftable section (3, 5) is positioned on each side of the fixed section (4), with a gap (22) therebetween. Preferably, the shiftable sections (3, 5) are interconnected (at 21) so that an axial adjustment of one section is synchronously transmitted to the other section and vice versa.
Claims17
A rail wheel milling cutter comprising a milling drive shaft (10), a plurality of carrier body sections (3, 4, 5) connected to said milling drive shaft (10) so as to be rotatable by said milling drive shaft (10), cutting elements (6, 7) secured to said carrier body sections for said milling, wherein at least one first carrier body section (4) of said carrier body sections is directly and rigidly connected with said milling drive shaft (10) for a direct torque application to said first carrier body section (4), wherein at least one second carrier body section (3 or 5) is mounted for axial displacement relative to said milling drive shaft (10) and relative to said first carrier body section (4) whereby a gap (22) is formed between said first end second carrier body sections, and wherein an adjustment member (31, 31A, 3A) is connected to said second carrier body section (3 or 5) for a stepless axial displacement of said second carrier body section (3 or 5) relative to said first carrier body section (4) into a fixed cutting position along said drive shaft (10) by adjusting a width of said gap (22) when said drive shaft is not operating, further comprising a guide roller coupled to said milling cutter in a position for engaging a side face of a wheel to be milled, and a drive connected to said guide roller for positioning said guide roller against a reference face of a wheel to be milled when the milling cutter does not rotate.
A milling cutter for milling rail wheel sets, comprising a milling drive shaft (10), a plurality of carrier body sections (3, 4, 5) connected to said milling drive shaft (10) so as to be rotatable by said milling drive shaft (10), cutting elements (6, 7) secured to said carrier body sections for said milling, wherein at least one first carrier body section (4) of said carrier body sections is directly and rigidly connected with said milling drive shaft (10) for a direct torque application to said first carrier body section (4), wherein at least two second carrier body sections (3 and 5) are mounted for axial displacement relative to said milling drive shaft (10) and relative to said first carrier body section (4) whereby a gap (22) is formed between said first and second carrier body sections, and wherein an adjustment member (31, 31A, 3A) is connected to one of said second carrier body sections (3 or 5) for an axial displacement of said second carrier body sections (3 and 5) relative to said first carrier body section (4) into a fixed position for cutting by adjusting a width of said gap (22), said milling cutter further comprising an axial displacement transmitting coupling (21) between said two second carrier body sections (3 and 5) so that an axial adjustment of one (3) of said two second carrier body sections is transmitted to the other second carrier body section (5) and vice versa, whereby both second carrier body sections (3, 5) are axially displaced in synchronism with each other.
A milling cutter for milling rail wheel sets, comprising a milling drive shaft (10), a plurality of carrier body sections (3, 4, 5) connected to said milling drive shaft (10) so as to be rotatable by said milling drive shaft (10), cutting elements (6, 7) secured to said carrier body sections for said milling, wherein at least one first carrier body section (4) of said carrier body sections is directly and rigidly connected with said milling drive shaft (10) for a direct torque application to said first carrier body section (4), wherein at least one second carrier body section (3 or 5) is mounted for axial displacement relative to said milling drive shaft (10) and relative to said first carrier body section (4) whereby a gap (22) is formed between said first and second carrier body sections, and wherein an adjustment member (31, 31A, 3A) is connected to said second carrier body section (3 or 5) for an axial displacement of said second carrier body section (3 or 5) relative to said first carrier body section (4) into a fixed position for cutting by adjusting a width of said gap (22), further comprising a guide roller (26) coupled to said milling cutter (1) in a position for engaging a side face (13 or 29) of a wheel (28) of said wheel set to be milled, and a hydraulic drive connected to said guide roller (26) for hydraulically positioning said guide roller against a reference face of a wheel (28) to be milled when the milling cutter does not rotate.
