A device is known, which, for elimination of rolling stock wheel defects during depot maintenance requires rolling out wheelset from under the wagon with the help of wheel-lifting devices.In this case each wheel is turned separately on a stationary machine.The offered device for elimination of wheel defects appearing while in operation, does not require rolling out wheelsets from under the rolling stock, the wheelset is turned simultaneously.This device can be used everywhere, where an asphalt or concrete lot is available at the level of railhead, and for turning of locomotive wheels an additional pit track is required.The assignment of the device applied for is to extend wheel service time, reducing rolling stock maintenance time.Technical result of the assignment is - elimination of wheel defects (sharp flange, reduced flange in case of wear and resurfacing).For this end for turning wheels of a locomotive with power traction motor, a support is set under the wheel being turned.The wheelset preliminary should be lifted and leveled against the railhead by 15-25 mm with help of hydraulic jacks of 30t lifting capacity.One of the jacks is placed on the support body and serves for its fixation against the wheel turned.60 V DC from a power supply is applied to the terminals of the traction motor of the wheelset turned.After energizing the wheelset starts to rotate at the rate 200-240 r/min.The holder of the turning tool is moving to the wheel surface to be turned and the turning process starts.The surface processed is checked by a locomotive profile gauge.Locomotive battery can be used as the power supply source.40V voltage is tapped off the battery by a portable copper cable of 40 mm???2 and applied to rheostat terminals.During a wagon wheel turning the wheelset preliminary should be lifted by 30 t lifting capacity hydraulic jack and leveled against railhead by 15-25 mm.Support is placed under the wheel being turned.An actuator is placed under the opposite wheel of the wheelset.One jack is placed on the surface of the support body, another - at the level of the surface of the actuator body.The jacks are the basic fixing link between the support and actuator roller against the wheelset turned.The device is connected to 220 V AC, 40 V and 100 A power supply.With the aid of the rheostat the actuator roller rotation rate is set to minimal - 100 r/min.According to the principle of friction gear the actuator roller is brought to contact with the wheel tread, the rheostat increases the actuator roller rotation rate and the rotation rate of the wheel turned is brought up to 200-240 r/min.The cutter holder with the cup-tip tool is moving to the surface turned and the turning process starts.The processed surface is checked by the wagon profile gauge.The further turning process is identical to the previous one.Video and photos of Mobile Railway Wheels Turning Device you can see at http://www.railwaywheelsrepair.com Article Tags: Mobile Railway Wheels, Railway Wheels Turning, Wheels Turning Device, Mobile Railway, Railway Wheels, Wheels Turning, Turning Device, Rolling Stock, Wheel Defects, Power Supply, Turning Process, Actuator Roller, Rotation Rate
