Introduction: Person on a public errand and public errand size term and English among them of the rolling bearing contrast and define the first part:
1 . Nominal the internal diameter ‘ External diameter noninal bore diameter outside diameter
Definition: Wrap up, it holds in place with a net to be basically cylindrical inner hole ‘ Cylindrical outer surface Diameter of the round cylinder on the surface of theory. In a radial level appointed, wrap up the diameter of the cone of holding the surface of taper hole theory in place with a net. Wrap up the sphere diameter of the surface of theory of holding the basic spherical surface in place with a net.
Explanatory note: As to the nominal external diameter of nominal internal diameter of the rolling bearing, it is generally real inner hole and basis value that the outer surface offsets.
2 . Nominal width nominal ring width of one set of circles
Definition: Distance between a theory terminal surface of circle two of bearing. Actual basis value that width offsets generally ‘ Basic size .
3 . Bearing nominal the width ‘ Bearing height nominal bearing width bearing height
Definition: Suits of two circle theoretical the terminal surface ‘ The back of the washer Among distance,bearing widththrust bearing is highly for limiting in heart . The intersection of bearing and actual width or the intersection of bearing and actual basis value that height offsets generally ‘ Basic size .
4 . The bearing actual width actual bearing width
Definition: To the axis thread of the heart bearing and two distances cut among the points of intersect of level to limit real terminal surface of one set of circles of the bearing width. Use the limited bearing width of terminal surface of inner circle and outer lane terminal surface.
Explanatory note: Roll sub bearing to the intersection of uniline and taper, for the intersection of bearing and the intersection of axis and line and following two the intersection of level and distance among the point of intersect: One level with the intersection of inner circle and actual level that the back tangent, another with the intersection of outer lane and actual level that the back tangent. The inner at this moment, outer lane rolls one and the back of inner circle are blocked inside of the side and rolled with all the son keep in touch.
5 . The bearing actual height actual bearing height
Definition: The intersection of thrust and the intersection of bearing and the intersection of axis and line and limit the intersection of bearing and high the intersection of washer and two actual the back, cut distance of level among the point of intersect.
6 . The bearing actual height leans towards difference deviation of the actual bearing height
Definition: Thrust bearing actual height and nominal and high difference.
7 . Nominal to pour the angle size nominal chamfer dimension
Definition: As pouring the angle size of basis.
