Single Row Ball Slewing Bearing and ordinary bearing What is the difference
Single Row Ball Slewing Bearing and ordinary bearing in the work effect and size are different, then, Single Row Ball Slewing Bearing and ordinary bearing what is the difference?
Single Row Ball Slewing Bearing and bearing the same hair, have a rolling body and rolling roller with a raceway. But compared with ordinary rolling bearings, or there is a big difference. The following Orson single ball slewing bearing Co., Ltd. is to say the difference between the two.
Single Row Ball Slewing Bearing and the difference between ordinary bearings:
1, Single Row Ball Slewing Bearing size than ordinary bearings are large, its diameter is usually 0.4 to 10 meters, and even some of the diameter of 40 meters.
2, generally have to bear several aspects of the load, not only to bear the axial force, radial force, but also bear a greater tipping moment. Therefore, a single row of ball slewing bearings can withstand the role of several ordinary rolling bearings, the force is greater than ordinary bearings.
3, Single Row Ball Slewing Bearing running speed is very low, usually 10 r / min or less. In addition, in most cases, the bearings do not rotate continuously, but only in a certain angle of rotation, equivalent to the so-called "swing bearings."
4, in the manufacturing process, materials and heat treatment, Single Row Ball Slewing Bearing and rolling bearings are very different.
5, usually, Single Row Ball Slewing Bearing with a rotary drive ring gear and dust with the sealing device.
Rapid economic development, bearings are widely used in life. Speaking of bearings, Single Row Ball Slewing Bearing should be the most widely used in the bearing, but also mechanical indispensable spare parts. Bearing maintenance work is particularly important for Single Row Ball Slewing Bearings, the following describes the Single Row Ball Slewing Bearing maintenance work matters.
1, bearing the bearing installation, to have enough rigidity, the installation surface to be flat. Single Row Ball Slewing Bearing bearings to be stress treatment to reduce the bearing deformation, in the assembly of the single ball to the ball bearing contact surface clean up.
2, Single Row Ball Slewing Bearings in the bolt completely tightened before the gear to engage with the check, the meshing conditions should meet the gear accuracy requirements: the gear pair in the slight brake operation on the tooth surface after the distribution of contact spots in the teeth Not less than 25% in the height direction, and not less than 30% in the longitudinal direction of the teeth.
3, in order to ensure the reliability of the bearing, after 100-500 hours of work, to check the bearing bolt tightening torque, in the subsequent 100 hours to check the preload torque.
4, when tightening the nut, the threads and nuts on the surface of the application of lubricating oil, and torque wrench in the circumferential direction symmetrical uniform tightening several times.
5, the bearing should be placed in the non-corrosive non-corrosive media, dry, flat indoor, not soaked or water shower.
6, Single Row Ball Slewing Bearings should be placed smoothly, to avoid vertical, inclined or hanging. At the time of placement, each bearing has at least 3-5 pads placed in the circumferential direction, and the upper and lower blocks should be aligned at the circumference. Idle for many years the bearings, when used in time to check.
7, if not the use of Single Row Ball Slewing Bearings, to be carried out once every 6 months, the outer surface of oil maintenance to prevent corrosion. And the bearing raceway will have to carry out a year of lubrication maintenance, maintenance is to check the single row of ball slewing bearings are flexible operation. After the relevant maintenance, the bearing back to the initial state, and packaged with a good film.
