Problems solved by technology

[0005] It can be seen from the previous error analysis that since only one instantaneous value is measured for zero measurement, the subsequent measured values ​​are all based on this instantaneous value, and the instantaneous value is random, which will inevitably bring errors to the measured value. This error can be reflected in multiple measurements of the same bearing

Abstract

The measuring device is composed of mechanical part, pneumatic control and electric part. The mechanical part includes centre shaft connecting down end with lifting mechanism, air mainshaft and babber matching up with standard ring or bearing to be measured. The working platform has centre hole with its down end face connected to upper ring of air floating-thrust bearing. The bearing down ring is connected to down end of connecting ring having retainer ring on it. The displacement transducer passes through inner hole of the connecting ring to contact with standard ring or end face of inner ring at bearing to be measured as its upper end is connected to electric part or indicating meter.

Description

technical field [0001] The invention relates to a metering device, in particular to a measuring device for bearing protrusion. Background technique [0002] The more advanced bearing protrusion measurement device currently in use consists of a mechanical part, a pneumatic control part and an electrical part. Among them, the mechanical part mainly includes the base, the air spindle system and the measuring and adjusting device; the pneumatic control part includes the pressurized cylinder, the compressed air pipeline, the air pressure gauge and the control valve; the electrical part includes the computer, the measuring circuit, the displacement sensor and the printer. [0003] The measurement process of this type of instrument is carried out in two steps, the first step is zero measurement: put the sensor on the center of the end face of the measuring anvil, first install the standard ring, add the measurement load, and perform static measurement to ...
