Rolling in the use of the minimum load

 Kunshan imported bearings, bearing the minimum load: When the load is too small - such as high speed operation, will produce skidding, if lubrication is not sufficient then lead to bearing damage. The following is recommended that minimum load bearing:
With cage ball bearings P / C = 0.11
With cage roller bearings P / C = 0.02
No cage bearing P / C = 0.04
(P is equivalent dynamic load, C is the basic dynamic load rating)
The minimum load thrust bearing from the bearing surface dimension table money was found in the overview.
Excessive size reduce bearing life: The reason is oversized bearings prone to slippage, and to the original design for the life of the lubricant life, internal working stress increases. Slippage will cause agglutination and reliable work weeks to more than seeking full advantage of the bearing capacity. Therefore, as in the bearing life calculation according to the modified method, in calculating bearing life, in addition to the basic load rating, it must also affect the bearing of other factors.
 Kunshan clutch bearing, hydrostatic bearings advantages: 1. Pure liquid frictio, friction is small, small power consumption, high transmission efficiency.
(2) normal operation and frequent starts, will not occur from direct contact between the metal wear, maintain good accuracy and long life.
3 due to the floating shaft is to rely on external pressure of the oil to achieve, therefore, relative motion in a variety of speeds, have a high carrying capacity, speed change little effect on the film stiffness.
4 lubricant layer has a good anti-vibration performance, shaft smooth operation.
5 film has the effect of compensating for the error, the shaft and the bearing itself can reduce the impact of manufacturing errors, kicking high precision turning shaft.
6 hydrostatic bearing design, as long as a reasonable choice of design parameters, such as seal oil surface size, throttles form, oil pressure, throttle ratio, etc., can make the bearing capacity, film stiffness, temperature, etc. to meet light load to heavy, low speed to high speed, small to large variety of mechanical equipment.
