Clearance inspection machine

Equipment purpose

Cleaning and testing machine, used for checking the rotational flexibility and axial clearance of deep groove ball bearings

The device includes functions

a) Flexibility check

b) Axial clearance inspection

technical indicators

The range of outer diameter dimensions for machinable bearings is: φ 12 to φ 30mm, φ 30 to φ 60mm, and φ 60 to φ 90mm;

Measurement system recognition accuracy: 0.1 μ m

Measurement frame comprehensive accuracy (measurement accuracy): 1 μ m

100% identification of rotating defects such as jamming, emergency stop, and ball jamming;

100% identification of defective products with clearance (based on input conditions);

The measurement error between the axial clearance gauge and the mechanical instrument is less than 3 μ m;

Measurement system capability index Cgk>1.33;

Axial clearance inspection: Method: Horizontal measurement. The bearing is transported to the workstation, with the outer ring of the bearing fixed. Pressure is applied to the inner ring up and down to detect its movement. The recognition accuracy is 0.1 μ m, and the static repeatability is 3-5 μ m. The measurement is made using solid standard parts, and the repeatability is ≤ 2 μ m;

The pressure of the upper and lower pressurization must comply with the relevant standards for clearance measurement, and the pressure can be adjusted according to different models. The lower pressurization is equipped with a pressure sensor;

Work efficiency: 4.0-6.0 seconds/set
