Jiaxing bearing | eccentric bearing control method of prestressing quantity adjustment windage are all here, hurriedly collection!

There is rotational, have HRB bearing ( ) In view of the eccentric bearing pre-tightening adjust clearance control of the subject, today we invite our jiaxing bearing engineer for everyone to do a detailed introduction and guidance, hope everyone can learn. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Bearing preloaded during the installation process to control the amount of main is angular contact ball bearing, eccentric bearing, tapered roller bearings, taper Kong Shuang row cylindrical roller and so on, in the final stages of this a few kinds of bearing installation is to accurately adjust clearance, namely prestressing quantity control ( Load) , especially for machine tool spindle, etc have strict request for rotating accuracy, noise, temperature rise of shaft system, not only in the installation for the first time to control the amount of preloaded ( Load) Adjust the clearance, but also need to adjust in use. Preloaded quantity control method is more, here are several control methods of prestressing quantity adjustment windage, company the author do the introduction for you. ( 1) , measurement of eccentric bearing friction torque starting, advance measuring bearing friction torque starting with the relationship between the axial load, to control the starting friction torque to adjust the amount of preloaded, commonly used to install in pairs of tapered roller bearing axial pre-tightening ( 2) , measuring bearing axial displacement, the taper hole bearing measurement in advance eccentric bearing axial load and the relationship between the axial displacement, to control the axial displacement measure to adjust preload ( 3) And measure the preloaded spring deformation, measuring the relationship between load and deformation of the spring, in advance to adjust to control the deformation of prestressing load (constant pressure 4) , measuring nut tightening torque, the nut preloaded bearing, to control the tightening torque of the nut to adjust the preloaded quantity ( 5) , adopt bearing end cover and mat, will cause end tighten, the other end of the first bearing not put into the gaskets, tighten the screws, when feel shaft can not be free rotation, within the shafting has no clearance, with a feeler gauge amount out of the cover and bearing seat end clearance, will this value plus the clearance value is the thickness of the gasket ( 6) , using interval sets, in the inner ring spacer length can be supported by the bearing outer ring spacer length and calculate the size, also can be measured to determine the eccentric bearing pre-tightening load test is more difficult, a few with a special instrument to detect, the majority of the shaft with a dial gauge test axial and radial displacement of the starting friction torque to test or measurement, some foreign bearing companies remain the best value for the pre-tightening load, using special instruments and some structure of pre-tightening load testing and adjustment, realize the pre-tightening load can be controlled.
