(1) The sound of the cage and its control method The sound of the cage is the periodic oscillation and noise announced by the violently oscillating cage and the impact of the roll; it is easy to present when the pocket is loose and the conflict is large. Attack in ball bearings and tapered roller bearings; and both the stamping cage and the solid cage can occur; when the grease is smooth or the oil is smooth, it will occur; but when the smoothness is smooth or the smoothing agent is dry, when the radial clearance is large, When the outer ring receives the moment load; and when the cage layout is poor and the accuracy is not high; it is easier to attack; in severe cases, the cage web or rivet head will crack.
The method of controlling the noise and oscillation of the cage is to use a smoothing agent with good smoothness, to reduce the bearing error of the bearing, to tighten the radial clearance of the bearing or to properly axially pre-tighten, and to select a cage with a reasonable layout and a reasonable layout. Bearing; or replace the bearing with a strong and unworn cage.
(2) vibrating sound and its control method vibrating sound is the noise directly related to the bearing wrinkling appearance waviness; this is a pure tone noise; about the stable speed; its frequency is also unchanged; and about the changed speed; Its frequency also changes.
