Background
The single-row short cylindrical roller bearing is widely applied to the industries of passenger vehicles, commercial vehicles and engineering machinery, and the finished bearing needs to measure the radial clearance and carry out matching so as to achieve the precision required by the process.
At present, the clearance measurement of a single-row short cylindrical roller bearing is to apply a stable downward pressure to a bearing inner ring manually, keep the bearing inner ring still and apply a certain radial force to a bearing outer ring, wherein the measured value is a bearing clearance value; taking an NJ314 short cylindrical roller bearing as an example, a conventional measurement procedure is as shown in fig. 1, where a reference end face of a bearing inner ring 4 is placed on a platform. A stable central axial load 8 is manually applied to the upper end face of the inner ring 4 to ensure that the bearing inner ring 4 is fixed, a certain radial load 9 is manually applied to bearing outer components, namely the outer ring 1, the retainer 2 and the roller 3, the indicator 6 is locked by a locking screw 7 through the fixed support 5 and is arranged on the outer surface of the outer ring 1, and the difference between the maximum reading and the minimum reading of the indicator 6 is the radial play value of the complete set of bearing.
Whole testing process is very high to the operating requirement, and intensity of labour is big, personnel are tired very easily, need two skilled operating personnel to measure simultaneously usually, and it is longer to detect one set of bearing time-consuming, and detection efficiency is very low, and it is very urgent to need a device that can stabilize high-efficient measurement short cylindrical roller bearing play now.
