Abstract

A method for grinding cast steel railroad wheels is provided. The apparatus comprises a railroad wheel support assembly that includes a roller assembly to receive and grasp the railroad wheel and rotate the railroad wheel about its center axis. A grinding assembly is also provided that includes a motor operatively connected to a grinding wheel. The motor and grinding wheel are mounted to a support assembly. The railroad wheel support assembly oscillates about an axle assembly during grinding. The grinding assembly is designed to advance the grinding wheel laterally into the railroad wheel during grinding. The lateral advancing of the grinding wheel and oscillating of the railroad wheel are controlled to achieve a finish grinding of the selected surface of the railroad wheel to a preselected contour.

Claims6

Dependent claims

A method of grinding a railroad wheel comprising the steps of loading a railroad wheel into a railroad wheel support frame, connecting railroad wheel support drive roller means to said railroad wheel support frame so that said railroad wheel is held in said railroad wheel support drive roller means and is rotated about a center axis of said railroad wheel when so held,

providing a grinding wheel support assembly comprising a grinding wheel motor, a grinding wheel operatively connected to said grinding wheel motor, a grinding wheel support frame onto which said grinding wheel motor is mounted, and moving said grinding wheel support frame such that said grinding wheel is brought into contact with said railroad wheel,
providing railroad wheel support frame axle and bearing means and providing flange sections extending downwardly from said railroad wheel support frame, receiving said railroad wheel support frame axle means into openings with bearing means in said flange sections,
providing a first operating cylinder and attaching one end of said first operating cylinder to said base frame and attaching another end of said first operating cylinder to said railroad wheel support frame bearing means such that upon extension of said first operating cylinder, said railroad wheel support frame is rotated about said railroad wheel support frame axle means to expose a surface of said railroad wheel to said grinding wheel.
