The invention relates to the technical field of maintenance on trains, in particular to a device and a method for measuring bearing clearance of gear wheels of gear cases. The device for measuring the bearing clearance of the gear wheels of the gear cases comprises a positioning connecting piece, a plurality of suction elements, two measuring arms and two position measuring gauges. The device and the method have the advantages that the positioning connecting piece can cling onto bodies of axles, can be stably sucked with collecting rings by the aid of the suction elements, can be quickly and accurately fixed and is high in positioning efficiency, the two measuring arms are symmetrically arranged, the position measuring gauges are respectively arranged on the two measuring arms, are symmetrically arranged and are positioned at the same horizontal altitude, heads of the position measuring gauges are in perpendicular contact with the end surfaces of bearing covers of the axles, and accordingly the bearing clearance can be accurately measured; working procedures for mounting magnetic gauge seats and adjusting dial gauges by two workers in an existing measuring mode can be omitted by the device for measuring the bearing clearance, accordingly, the labor cost can be saved, and manual operational errors can be prevented.
Description
technical field [0001] The invention relates to the technical field of train maintenance, in particular to a device and method for measuring the clearance of a large gear bearing of a gearbox. Background technique [0002] Usually, in an EMU train, a gearbox is installed on the axle, a corresponding bearing is installed on the side of the large gear of the gearbox, a bearing cover is arranged outside the bearing, and a collector ring is arranged outside the bearing cover. In both cases, it is necessary to measure the clearance value of the bearing on the large gear side of the gearbox. At present, two magnetic gauge bases are used to adsorb on the axle body at 180°, and a dial indicator is used for measurement. [0003] However, the above measurement method has the following disadvantages: 1. Low efficiency. The paint on the axle body is thick, and it is difficult for the dynamometer seat to be effectively adsorbed on the axle body, so repeated adjustments are required. 2...
