Product Description
Spherical roller bearings: 1. and tumbling bearings with the same volume of load strength to be much larger. 2, vibration and noise is small, used in the circumference of the density requirements of high, and should not be allowed to have the vibration of the field. 3, the formation of the metal of foreign objects is small, not prone to early breakage.What are the common main features of spherical roller bearings?Spherical roller bearings are bearings with drum-shaped rollers assembled between the inner ring with two raceways and the outer ring with spherical raceways. Spherical roller bearings produced by Noble Xuan Bearing Co., Ltd. have two rows of rollers, mainly to bear radial load, but also can withstand any direction of the appropriate amount of axial load; have a high radial load capacity, don't apply to radial heavy loads or vibration load work, but can't withstand the pure axial load.The main points of the spherical roller bearings are:(1) and spherical ball bearings are similar, spherical roller bearings, the outer ring raceway is a spherical part of the curvature of the center in the bearing axis, this type of bearing outer ring raceway is spherical shape, so its centering performance is good, can compensate for the coaxiality error, so you can realize the automatic centering.(2) in the section perpendicular to the rolling direction, the roller busbar is curve, and inside and outside the raceway can be a good match, the roller and the raceway is a line contact, can withstand radial load and axial load, has a good impact resistance.(3) Spherical roller bearings of the rollers and raceways of the high degree of coincidence, and are curved bus, so the relative sliding is serious, friction than cylindrical roller bearings, so the spherical roller bearings allowed to work at a lower speed.(4) ordinary withered roller bearings with asymmetric roller, operation will produce an axial force, roller by the action of this force and contact with the center of the fixed edge, symmetric roller spherical roller bearings, it can be moved along the axial movement of the activities of the intermediate ring, so that the roller is no longer subject to the constraints of the center of the edge, and eliminates the inner ring raceway retractor groove, you can use the longer rollers, thereby improving the bearing capacity. Bearing capacity.(5) single row spherical roller bearings contact angle is 0, in the axial load contact angle does not change significantly, a very small axial load will produce a large contact force between the roller and raceway, so when the axial load is relatively larger than the radial load, single row spherical roller bearings can not withstand radial and axial combined load.(6) Similar to self-aligning ball bearings, double row self-aligning roller bearings with tightening sleeves can be mounted on any position of the optical axis without machining the locating shoulder.Spherical roller bearings before installation precautions1,Check the bearings have no quality problems. Whether the rotation is flexible, carefully check the surface of the bearing parts for defects, such as indentation, burns, cracks and so on. Strictly prohibit the loading of parts with quality problems.2,Ensure that the installation site is clean, and strictly prevent foreign objects from entering the bearing interior.3,Ensure that the bearings are clean, do not install the bearings without cleaning.Ensure the quality of seals. Carefully check whether the seal type specification, size is appropriate, whether there are defects or quality problems, whether the relevant accessories are complete and whether the fit is reasonable.Spherical roller bearing installation precautions1, avoid hard mounting, impact, must ensure that gently loaded into the bearing, bearing and seat hole for the small gap fit, normal conditions should be lightly tapped on the end of the positive position loaded into the force of the impact to the tilt is not easy to load, so that the bearing seat hole surface killed and injured or even scrapped.2, bearing inner sleeve must be installed with induction heating, and shall not exceed 120 ºC. It is strictly prohibited to dismantle the bearing by open flame heating.3, not good to load, find out the reason, eliminate the problem after taking reasonable measures, found that there are parts deformation and other problems should be repaired in a timely manner, if necessary, to modify the drawings.4,Inject sufficient and clean grease strictly according to the requirements. - Installation of unqualified seals, gaskets and other parts found, must be strictly scrapped or repaired to ensure that the assembly quality in line with quality requirements.
