The current steel ball has low precision, large noise and large vibration during movement, and cannot achieve the effect of quiet rotation of the bearing. Quiet steel ball The utility model relates to a steel ball, in particular to a steel ball suitable for a bearing, in particular to a steel ball with a mute effect suitable for a bearing.
The silent steel ball of the utility model is manufactured by the grinding wheel grinding method, so that the surface of the steel ball is ground to form fine grooves, and these fine grooves can be used as natural oil storage points, so that there is always a Lubricating oil, which greatly improves the performance of the steel ball, especially has a good mute effect.
The various indexes of the silent steel ball of the utility model reach the G5 standard, and some indexes reach the G3 standard. The silent steel ball is characterized in that: its surface has several small grooves formed by grinding with a grinding wheel, and the small grooves are irregularly arranged.
The spherical Stainless Steel Ball error is less than or equal to 0.08um, the variation of the ball diameter is less than or equal to 0.20um, and the surface roughness is Ra≤0.008, Ry≤0.060, and Rtm≤0.035. The utility model solves the problems of large noise and large vibration generated by the current steel ball when the bearing is running.
