The installation of columnar aperture bearing

With the method that compressor presses small-sized bearing uses the method that compressor presses extensively. If the graph is shown 1 times, withstand space block inner ring, press slowly to inner ring end panel with compressor clingy axis shoulder. Withstand outer lane space block installs inner ring, the impress that can cause raceway to go up or press, prohibit absolutely so. Moreover, when the operation, should cooperating a face to go up beforehand oiled. Beat the circumstance of installation with hammer as a last resort, want inside to encircle the space block on overlay to work. This kind of practice causes bearing loss time and again, so, the state of affairs with little interference of be confined to, cannot use at interference big or medium, large bearing. Blame depart bearing is like deep trench ball bearing, inside, the situation that outer lane has needed to be filled with installation, if the graph is shown 2 times, with screw or oil pressure, use space block will inside, outer lane is pressed at the same time. Outer lane of the ball bearing that move a heart is easy tilt, although not be to be filled with too,cooperate, the space block on best also mat is installed. Depart bearing is like columnar roller bearing, tapered roller bearing, can will inside, outer lane installs axis and bearing respectively on. When combining the inner ring that has installed respectively and outer lane, crucial firm quietly is shut, prevent both center deviate, reluctance pressing initiate is caused roll face abrade. The method of shrinkage fitting is large bearing, pressure fashionable the power with very great need, work very hard so. Accordingly, use shrinkage fitting method extensively: Heat in oil bearing, make expand, install an axis next. Use this kind of method, won't appear when installation get the case with undeserved force, can shorten basic cycle time. Of bearing heat temperature, with bearing dimension, needs interference, referenced graph 3 decisions. Shrinkage fitting exercise concerns a note, following. (A) bearing heats cannot exceed 120C. (B) to make bearing does not contact oil groove bottom, answer to put bearing in gauze to wear, or trice. (C) is operated to prevent in, because of inner ring temperature drops and be hard to install, heat temperature tower above should need than place when bearing 20 ° C, 30 ° C. (After D) is installed, bearing is cooling, width direction also can contract, want to use the method with axial nut or appropriate other so, its locking, in case inner ring and bearing are blocked gap produces between the shoulder. NSK induction adds shrinkage fitting buy to divide the shrinkage fitting that use oil outside, the NSK response that uses electromagnetism induction principle adds shrinkage fitting buy to also be used extensively. NSK induction adds shrinkage fitting buy, excitation coil is installed inside, electrify hind because electromagnetism induction action, electric current is passed heat body (bearing) , produce quantity of heat by the impedance of bearing oneself. Because this can be inside short time, need not fire, oil heats equably. The efficiency of shrinkage fitting exercise of bearing is tall, clean. Outfit, tear open more frequent occasion, if axle box of traffic of roller bearing, railroad uses columnar roller bearing, the installation that can use the special induction of NSK to add shrinkage fitting buy to undertake inner ring, disassemble. The bearing of installation taper hole of conic aperture bearing secures inner ring axis of Yu Zhui form to perhaps be used directly cover closely surely, disassemble cover installation to arrive on columnar axis (if pursue 4, graph 5) . Bearing of the large roller that move a heart is multi-purpose oil pressure installation, graph 6 it is to use hydraulic pressure nut to press the case that decides an installation closely. Graph 7 be covering closely surely on install oily aperture, send high-pressured oil at the same time coordinate a side, press the method that covers installation closely surely with bolt at the same time. Of the bearing that move a heart press quantity reference to express 1. Examine the decrement of radial windage, undertake installing. Feet of use a place of strategic importance measures windage, if the graph is shown 8 times, measure two windage at the same time, want basic and equal numerical value. Increase as the dimension of bearing, when installation arrives on the axis, because self-prossessed outer lane produces ellipse to be out of shape, if be in,be out of shape bearing most bottom measures windage, measures number can be more than actual windage, with this wrong radial windage, press a watch of 1 roughly standard installation, can cause interference too big, or actual installation windage is too small. Because if the graph is shown 9 times,this wants, what make the same score direction with water is transverse A of two place windage, B and most the half of the summation of bottom windage C serves as windage. The ball bearing that move a heart is used when covering installation closely to arrive on the axis surely, want to ensure outer lane can move a heart neatly, the windage after installation cannot pass small.
