Cylindrical roller bearing, ball bearing steel ball is how to put it in

& emsp; & emsp; Wind turbines have fire accident, there are also abroad, the unit in the replacement of generator, coupling, coupling cover and destroyed part of the circuit and sensors, connected to the grid. RPM, on the basis of gear box ratio calculation rate kW; : : unit kW power; : : unit kW power; Sets high speed spindle speed and low speed shaft speed matching, there is no coupling skid phenomenon, such as: : actual generator rotation speed of the unit. Bearing wear the fast repair steps, & amp; emsp; & emsp; The solution of the problem & amp; emsp; & emsp; According to the above analysis, processing the QS - years improvement /- 。 Only inner and outer ring with penal single bearing can follow the constant axial load of smaller or larger intermittent axial load; Compared with other tired socket in the shape of the same size, this kind of bearing with high load, at the end of the noise and the characteristics of high speed and roller and ring guard friction small, suitable for high speed spinning. Structure and working principle of rolling spline pair, rolling spline pair composed of spline shaft spline set of ball bearing and circulating device, a mutual into ° on spline shaft spline, the spline are on both sides of the ball and the raceway, the row ball is used to transfer torque, forward another column for reverse torque. According to the direction of load bearing, bearing can be divided into the centripetal bearing ( Bear radial load, also known as the radial bearing) The thrust bearing ( Carry axial load) And centripetal thrust bearing ( Bear radial and axial load at the same time, also known as the radial thrust bearing) 。 Heater is it a picture at the same time heating bearing and a fixed axle bearing small manual, summed up the bearing code classification, when you see this, maybe some code now you did not contact, but I believe, as long as you are bearing, need it in the future will have a day! The classification of the bearing from left to right for the first two or a first part and the Numbers add up ', 'said deep groove ball bearing) '' double row deep groove ball bearing) '' or' 'said self-aligning ball bearings, The basic model Numbers) Class) '' '' '' '' said self-aligning roller bearings. Its service life more than any kind of repair process, the traditional sliding bearing: no rolling body, rely on a smooth surface to support the axis of rotation, and the contact area is a surface, not completely liquid lubricated bearing bushing wear serious, need to be replaced periodically, rotating accuracy comparison due to rolling bearing radial clearance is small, high rotating accuracy. Bearing damage, caused by bearing in appearance does not have evident in the external features, either forward or reverse can be installed, the phenomenon of extremely easy to appear. When the bearing inner ring and the shaft is a tight fit, the bearing outer ring and bearing seat is a loose fit, bearing on the shaft installation first, and then will play an load bearing hole of shaft with bearings. Air dynamic bearing pressure air film is through the mutual movement of the sliding pair bring air into sliding pair of convergence between surface area and formed, gas film roughly wedge-shaped. (poor lubrication bearing the percentage of the damaged reasons: About %) , is a major cause of premature bearing damage caused by poor lubrication, lubrication pollution ( About %) , pollution can also cause premature bearing damage, pollution refers to such as dust, scrap metal, or other material into the inside of the bearing.
