DEVICE FOR FILLING BUCKS motor-axial bearings LOCOMOTIVE WITH ELEMENTS OF DIAGNOSIS

摘要

refilling apparatus axlebox motor-axial bearings on locomotive level includes a control unit composed of electronic elements oil passage pnevmogidropult compressor for injecting low-pressure air to the signal port pnevmogidropulta, a stepping motor as an actuator for the oil pump. In this case, the control unit introduced controller that calculates the amount tucked lubricant on the basis of the number of revolutions of the stepper motor, determines the geometrical parameters of the journal box and the number of additional charging lubrication position of the level of lubricant in the spare chamber axlebox at the moment before filling, which is then compared with the critical oil level in the spare camera to determine the technical condition of the journal box and motor-axial bearing as a whole.
