The tapered bore bearing directly fixes the inner ring to the tapered shaft or may use the adapter sleeve to disassemble the sleeve device onto the cylindrical shaft. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Large-scale spherical roller bearing multi-purpose hydraulic device; it is used to press the hydraulic nut into the adapter device. Figure 7 is to set the oil hole on the adapter sleeve; while the high-pressure oil is sent to the cooperation surface; The method of tightening the device.
Check the reduction of the radial clearance; carry out the device. Use the feeler to measure the clearance; measure the clearance between the two columns together; the value should be flat at all.
The scale of the bearing increases; when the device is on the shaft; the elliptical deformation occurs due to the outer ring of the self-weight; if the clearance is measured at the lowermost part of the deformed bearing; the measured number will be larger than the practice clearance; the radial clearance with this fault; According to the general specification of Table 1, the interference will be too large; or the practice device clearance is too small.
When the self-aligning ball bearing is used to fix the sleeve device to the shaft; make sure that the outer ring can be sensitive and aligning; the clearance behind the device should not be too small.
