The long ball bearing: choose in vertical shaft bearings

If often remove the different diameter of inner ring, it is recommended to use adjustable induction heater, the heater ( Figure can be quickly heated inner ring, and doesn't make the shaft gets hot. Press the formula obtained: specified life (L: km） FH: hardness coefficient ( Refer to figure - C: the basic dynamic load rating ( N) FT: temperature coefficient ( Refer to figure - P: load ( N) Fc: contact coefficient ( Reference table - Life time can be achieved by the walking distance of unit time to calculate. Rotary roll than & amp; emsp; & emsp; And do not require complicated outsourcing and offline operation can complete, and not to damage the original equipment, repair after the original equipment service life is also the first one. Processing: tighten the foundation screw, bearing of machinery space and location in mechanical design, make sure of the size of the shaft, then choose rolling bearing according to the size of the shaft. It is under the preloaded change is less than the cause of the constant pressure preload, therefore, the ball when the increase in the number, should increase pre-tightening load, only when the contact load count to make the bearing stiffness increases at the same time. Compared with the size of the other kinds of bearings, the bearing has a small friction coefficient, high limit speed, manufacturing high accuracy, easy to realize the characteristics of bearing seal, the types of bearing is the user. Prevention of moving cone imbalances, bearing use note bearing is precision components, but no matter how high performance bearing, use if use undeserved, will not get the desired effect. Cage cage, cage） , namely the bearing cage, also known as the bearing retainer, refers to the part of the package all or part of the roll body, and with the movement of the bearing parts, used to isolate rolling body, usually also guide roller and keep it in the bearings. Business people mainly learn the user's actual load is consistent with the selected bearing, if bearing can not meet the use requirements, should suggest customer re-election model as soon as possible, but unless special products on the selection model will not have what problem. Take the first round of testing, water ring vacuum pump in use process will happen sometimes bearing sound condition, if not handled in time often can cause the damage of water ring vacuum pump motor. In this paper, we share the choice of rolling bearing grease, linear bearing has advantages of small friction, high stability, almost all the machinery are used to, is a widely used parts. As shown, if adjust the gap to determine the axial input side, is the high speed shaft blank cap removed, with depth vernier caliper to measure the bearing from deep down in the plane of the end cover; Then the shafting by crow-bar tools to input side move, then measure the cap end bearing from the depth of the end cover plane, two depth size difference is bearing the amount of mobile.
