Jiaxing bearing: small make up take you grasp of improving the performance of the spindle component

There is rotational, have HRB bearing ( ) Jiaxing bearing: the authors take you grasp of improving the performance of the spindle component. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the 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 cash supply ability. In ensuring the spindle manufacturing precision and accuracy of bearing at the same time, choose the appropriate bearing preloaded and use the measures such as directional error of bearing assembly can also be further improve the rotation precision and rigidity of spindle component, for different types of bearings, pre-tightening device and method is also different, prestressing methods commonly used for mechanical design. In ensuring the spindle manufacturing precision and accuracy of bearing at the same time, choose the appropriate bearing preloaded and use the measures such as directional error of bearing assembly can also be further improve the rotation precision and rigidity of spindle component, for different types of bearings, pre-tightening device and method is also different, prestressing methods commonly used for 'mechanical design basis' books, go here. The front end of the rolling bearing the directional error of the spindle assembly must be positioning surface ( Outside cylindrical surface or surface of cone hole) 。 Before the installation of bearings, must first measure the bearing inner ring and radial beat circle on the surface of the positioning, and then press the directional fitting method to bearing assembly, can achieve the purpose of improving the spindle rotation accuracy. 1) With external cylindrical surface of the spindle because of processing technology, the axis of the surface of the shaft neck and the front cylinder positioning surface radial beat circle not only in the same amount of axial plane, and in the same direction, so the beat quantity of the bearing assembly is small, and the influence of not consideration; When assembling, should make the front and rear axle of maximum radial round beating in the same axial plane, and in the same side as the axis, which can reduce the end of the spindle radial circular runout, the spindle rotation accuracy. 2) With a taper hole on the surface of the spindle because of processing technology, the spindle axis neck surface and taper hole surface cannot be processed in a clamping, will inevitably produce relative to the axis of the radial circle dance. Before and after assembly when the main shaft bearing inner ring of the radial circular runout amount and the center line of the spindle taper hole deviation in the same axial plane, and are assembled in a certain direction, in order to improve the spindle rotation accuracy. After finishing special assembly precision of the spindle components, such as coordinate boring machine spindle component, main shaft bearing installed within the sleeve, the spindle taper hole of jitter tolerance only 1 & mu; m2μ m。 In order to guarantee the precision of the spindle component, can adopt the method of assembly after finishing, namely the spindle component assembly first, based on the spindle taper hole on both ends of fine grinding spindle sleeve cylindrical; Again on the basis set of Jane cylindrical, fine grinding in the hair shaft taper hole. Precision machine tool after adopting these methods quite high rotation accuracy, if you want to remove the bearing when repair, remove before, in between shaft and bearing inner ring, outer ring and housing ( Or spindle sleeve) Mark, should be done between assembly according to mark when installed, otherwise after reshipment precision is difficult to guarantee. 24-hour customer service hotline: if you are more interested in jiaxing bearing the author introduced the industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
