Jiaxing bearing | three typical bearing configuration forms in order to avoid bearing jammed

There is rotational, have HRB bearing ( ) 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. A shaft will often need two fulcrum, which is to support two sets of rolling bearing. And bearing configuration just solved the fulcrum bearing on how to axial shaft is fixed, and after the heat expansion bearings how to avoid the problem of stuck. The following author according to the understanding of the knowledge of bearing, bearing configuration to share the typical knowledge hope to be of help. Avoid bearing jammed, understand the three typical bearing configuration forms: 1, double protection the unidirectional fixed form of this configuration is to let each fulcrum of shafting axial fixed in one direction. Its defect is: as the two fulcrum were bearing cover is fixed, so when the axial thermal elongation, resulting in bearing by the effect of additional load, affect the service life. So in this form is only suitable for the working temperature is not high and the shaft is shorter ( Span L≤ 400mm) The occasion. For deep groove ball bearings should also in the bearing outer ring and bearing cover set aside axial clearance between C, C = 0. 2 to 0. 4 mm to compensate for the thermal elongation of the shaft. For angular contact bearings, thermal compensation gap on the inside of the bearing clearance. 2, a fulcrum bidirectional fixed and the other fulcrum swimming left for fixed protection, inherit the two-way axial force; Right end for swimming to stand, and only bear radial force, axial thermal elongation when can make the axial winding. When the axial force to the fixed protection can use deep groove ball bearings, around its outer sides were fixed. Upper part by the bearing hole convex shoulder fixed, this structure make the hole is not completed a boring, affects the machining efficiency and coaxial degree. Axial force is small hole available with elastic ring fixed outer ring. To bear axial force to the right, and inner ring fixed protection must also axial fixation. Swimming for protection, often use deep groove ball bearings, large radial force and cylindrical roller bearing can be applied. When choosing deep groove ball bearings, bearing outer ring and leave big space between the bearing cover, the axial thermal expansion can free elongation, but its coil axial fixation, in case the bearing looseness. When moving pivot using cylindrical roller bearing, for them, outer ring axial relative motion, axial fixed, so the inner and outer ring should be to avoid moving outer ring, cause excessive dislocation. Design should pay attention to the bearing inner and outer circle don't appear the excess or inadequate axial fixation. 3, travelling support on both ends when both fulcrum bearing designed to walk, the location of the shafting components required by other measures. For example: for supporting the herringbone gear shaft components, its location can be determined by the herringbone gear geometry, then swim two protection must be designed to support, but used to mesh with the herringbone gear of shafting components must be fixed on both ends, so that the two axes are axial positioning.
