The speed of the bearing is mainly limited by the temperature rise caused by the conflict heat inside the bearing; when the speed exceeds a certain boundary; the bearing will not rotate continuously due to burns, etc. The limit speed of the bearing means that there is no conflict to cause burns and heat. The boundary value that can be rotated continuously. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Therefore, the ultimate speed of the bearing depends on the type, size and precision of the bearing, as well as the smoothing method, the quality and quantity of the smoothing agent, the data and type of the cage, the load conditions, etc. The bearings are smooth and oily ( The limit rotation speed of the oil bath is not shown in the bearing scale table; its value indicates the rotation speed of the bearing depicted in the specification under normal load conditions (C/P>=13, Fa/Fr<=0.25 or so). Boundary value. Others; smoothing agent is different according to its variety and trademark; it can also be used for high-speed rotation although it is superior to other functions.
The rated speed of the limit speed is C/P<13 (that is, the equivalent dynamic load P exceeds 8% of the fundamental additional dynamic load C); or the axial load in the accepted component load exceeds 25% of the radial load; The following formula corrects the limit speed.
Na=f1*f2*n where na: the limit speed after the correction; rpm f1: the correction coefficient f2 related to the load condition: the correction coefficient n related to the composition load: the limit speed under the normal load condition; rpm (refer to the bearing scale Table) C: fundamental extra dynamic load; N{kgf} P : equivalent dynamic load; N{kgf} Fr: radial load; N{kgf} Fa: axial load; N{kgf} limit with sealed ball bearing The speed limit of the ball bearing with the touch seal (RS type) is limited by the touch surface speed of the seal ring; the speed of the wire is determined by the rubber material of the seal ring.
