SKF bearing load of scroll roller surface contact with the ball. With a examples ball bearing, bearing axis of line speed and distance of within ring roll road surface points is into is proportional to of ball line outside points away from ball of speed and rotating axis of distance proportion from, can seen, only a,, b two objects to same of speed, formed pure scroll, both will in it of volume revealed is does not same of line speed direction instead of two points of intersection, has sliding.
Differential slip and work closely with roll (rolling element and the Raceway radius of curvature than bus) is the relationship between very large, greater density, for large slip differential. Because of this, the product′s default, high rotation of the SKF bearing the necessary flexibility, you should choose the appropriate density is smaller.
When the ball rolls and poor road curvature radii of 20 percent, so badly behind larger than the elasticity of the sliding friction caused by friction.
Spinning exercise clearly caused by the friction of SKF bearings to move, if the default does not match the reasonable period of time, ring rolling around, likely came into contact with the Raceway surface normal rotation, began to slide, slide the sliding phenomenon is called self-rotating.
Contact ball must be greater than zero or rotation of the roller bearings SKF bearings began to slide. As thrust cylindrical roll child bearing, reverse rotating, if two set ring, roller speed line, speaker, ring long, roller speed roller speed and ring roll road of contact line speed of appearance of is is different, in speed began pure scroll of intersection ring roll road line crossroads, line speed both is drum will along contact surface of normal direction rotating direction instead, size same, led to sliding. This is the thrust force cylindrical roller bearing′s speed limit is not one of the high-end.
