Abstract
The invention discloses a clearance measurement device and method for bearing holding in a shaft holding box of a locomotive. The shaft holding box is stably lifted through an electronic scale; when the reading value of the electronic scale is a critical value of the sum of the weight of a shaft holding box assembly, the weight of a driven gear, the weight of an axle and the weight of other parts, the axial movement distance of the shaft holding box is the bearing holding clearance. In the whole measurement process, a non-tooth end bearing does not make displacement through measurement of a dial indicator, or else the result is invalid. Because the two ends of each motor mounting bolt hole of the shaft holding box are evenly stressed, the shaft holding box will not make elastic deformation, and therefore it is guaranteed that the measurement result is accurate.
