tapered roller bearings ntn demolition, with the precision

ntn bearing clearance adjustment. Radial bearing clearance with top clearance, side clearance, shown in Figure 1. Tip clearance can be kept liquid friction, the numerical size of shaft, rpm, the viscosity of the oil. Generally between control I/lO00d ~ 3/lOOOd (d axis diameter). Backlash is the role of the accumulation and cooling lubricants, the formation of the oil wedge, its value is changing, the more the smaller the gap to the bottom of the shaft, the bearing surface triangulation, the top side of the gap is about half the gap.
ntn bearing taper roller bearings imported several forms, but following the NSK bearings for the 14 tapered roller bearings. Each component must be installed in the correct order, and another near the end also has a recognition letter. Bearings and parts thereof, have the same identification number, and spacing ring is engraved with the part number and letter recognition, in this case for the B and C. This rule applies to six-figure named bearings. But not to the tapered roller bearings Inch.
Such parts as long as ring gap, a new SKF bearings do not check the clearance to install. But the contrary, if the bearings are used to check the gap with the appearance of other conditions.
Installation of the Department, bearing the parts needed in order of first, check all identification numbers and letters. If possible, can be bearing box upside down so that bearings can be installed from the top. This is the most convenient installation method, only by so doing can the bearing group established after the completion of loading in, which is subject to the bottom of the outer ring current positioning.
Insert time of ntn bearing demolition Note 2:
1. Hexagon wrench first release bearing with eccentric locking screw put on, and then insert the cap with a small iron bars put on the Shen eccentric hole, upstream along the axis of rotation to play loose eccentric sleeve.
2. Loosen the lock bolt housing. Together with the bearing from the shaft bearing unloaded. Note that the demolition of one end of bearing shaft before. Should be the other end of bearing shaft bolts loose, so that both ends of the bearing strength and damage each other.
The actual installation of bearing with precision, must be used not to bearing deformation measurement methods and measurement tools, on the bearing bore and the cylindrical surface co-precision measurement of the actual size can be the inner and outer diameter of the measurements all be measured and the measured data on a comprehensive analysis, based on this, precision worthy of the bearing axis and the seat hole the size of installation position. In the actual measurements with the shaft and the seat for the corresponding hole size and geometry should be measured in the bearings with the same temperature conditions.
To ensure the practical with the effect of a higher, shaft and bearing seat hole match with the surface, the roughness should be as small as possible. In making these measurements should be within the bearings and cylindrical hole, and the hole axis and the corresponding seat surface, near the assembly chamfer on both sides, were made to indicate the direction of the maximum deviation of two groups of markers, in order to In the actual assembly to match the maximum deviation of both targeting the same direction, so that assembly, both sides can be offset in part by the deviation.
Mudi directional signs to the two groups is on the bias compensation can be taken into account, even if both ends of the supporting Gezi's Rotation improve precision, You Shi's seat between the two bearing holes and Liangduan journal part of the concentricity error Dedao elimination. With the implementation of surface hardening on the surface of measures, such as sand blasting, with slightly larger diameter column precision plug first plug the hole, etc., are beneficial to improve the accuracy with
