Abstract
The present invention relates to an underfloor wheelset lathe for machining the profile of wheels (8, 9) of wheelsets for railway vehicles, in which the wheelsets are rotatably mounted in axle bearing housing outside the wheels (8, 9), with a machine bed (10), two supports mounted on the machine bed that can be moved in the X and Z-axis direction of the underfloor wheelset lathe and are provided for holding tools for the machining, entry track rails (5, 6) that can be removed during machining for positioning the wheels (8, 9) over the tools, clamping elements for gripping the axle bearing housings, roller pairs for each wheel (8, 9) for lifting, driving and lowering the wheelset before, during and after machining. The underfloor wheelset lathe is intended for installation in an inspection shaft (1) for rail vehicles. It has a machine bed (10) with a vertical height (11) that is less than the depth (2) of the inspection shaft (1). A lateral recess (15, 16) is located in the inspection shaft (1) in the area of each of the ends of the machine bed (10) for the purpose of accommodating the clamping elements, drives for the roller pairs and the removed entry track rails (5, 6).
