【 Jiaxing bearing knowledge 】 The rotating precision of rolling bearing

There is rotational, have HRB bearing ( ) In view of the rotating precision of the rolling bearing, jiaxing bearing group co. , LTD. The author want to speak today greatly, not to hurry up to my dear friends. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. The rotating precision of rolling bearing rotating precision of the rolling bearing is to point to: 1, the complete set of bearing inner ring and outer ring radial runout; 2, complete sets of bearing inner ring and outer ring end face a race to beat; 3, inner ring benchmark end face diameter to beat; 4 and exterior bus for reference face changes of slope; 5, the thickness of the thrust bearing race groove on the underside of quantity change. Symbols and definitions: 1, bearing the radial runout of Kia complete sets of bearing inner ring radial runout, refers to the inner ring in different angular position, the inner surface and the relative outer ring between the maximum and the minimum distance between a fixed point difference; Kea complete sets of bearing outer ring radial runout, refers to the outer ring in different angular position, the outer diameter surface and the relative inner ring between the maximum and the minimum distance between a fixed point. 2, bearing end face of raceway Sia complete sets of bearing inner ring end face of beating raceway, refers to the inner ring in different angular position, the radial distance from the inner ring axis is equal to the diameter of inner ring raceway contact of half, a fixed point relative to the outer ring and inner ring reference face the difference between the maximum and minimum axial distance between. Sea of complete sets of bearing outer ring end face of beating raceway, refers to the outer ring in different angular position, from the outer axis radial distance is equal to the diameter of outer ring raceway contact of half, outer ring between the reference face and a fixed point relative to the inner ring as the difference between maximum and minimum axial distance. 3, benchmark bearing inner ring end face diameter beat Sd benchmark inner ring end face diameter of beating, refers to the axis of the radial distance from the inner circle is equal to half of the raceway contact diameter, perpendicular to the plane of the ring axis line and the ring reference face the difference between the maximum and minimum axial distance between. 4, bearing outer surface busbar for reference face external surface of the gradient changes of SD bus for reference face amount of changes in the slope, and the outer ring of the reference face in the tangent plane parallel to the radial plane, outer diameter surface ( Remove both ends maximum axial chamfer size) Within the limit of the length, the relative location of each point on the same bus changes in the total amount. 5, shaft ring, seat ring raceway Si axial ring rolling on the floor thickness changes quantity changes in the way to the bottom thickness, refers to the central shaft circle across the floor with groove between the difference between the maximum and minimum axial distance. Se seat race to the bottom thickness changes in the quantity, refers to the seat bottom and middle race across the the difference between the maximum and minimum axial distance between.
