Spherical Roller Elevator Bearings Definition

Spherical roller bearing is in the article has two ways the inner circle and rolling rolling way for outer surface, between the drum assembly roller bearings.

Common characteristic

• Have two trains symmetric type spherical roller

• There is a Shared between the spherical groove

• Inner circle have two and Angle of the tilt a bearing axis groove

• Have good self-aligning performance

 

 

Have 2 Types according to Roller section shape

 

 

(1)Symmetric spherical roller

• Good impact resistance ability

• But works at low speed




(2)asymmetric spherical roller

• mainly services for host maintenance

• Operating temperature is low so can adapt to a higher speed

Bearing should bear Certain minimum size of radial load, Press the type estimate :

 

Fr =0.02C

  

Fr -- Minimum radial load N

 

C— The basic dynamic load bearing rated N

 

Equivalent dynamic load  

P=Fr+Y1Fa  Fa/Fr e

 

P=0.67Fr+Y2Fa  Fa/Fr e

 

P— Equivalent dynamic load N

 

Y1 Y2—Axial moving load coefficient

 

 

Equivalent static load  

P0=Fr+Y0Fa

  

P0— Equivalent static load N

Y0—Static thrust load

Special Materials Spherical roller bearing

Can work long life at high temperature 250 degree is 30 times than plain bearing. Prevent surface damage, seven times the ability of spalling.1.4 times the ability of bruises, 2.5 times the wear ability, high temperature condition the size stability, in 250 °C and almost no size changes
