    摘要: There are provided: a linear motion guide device, which enhances workability of raceway surfaces and is capable of reducing production cost; and a production method for the linear motion guide device. For this purpose, a linear motion guide device includes a guide rail (1), a slider (2), and a plurality of rolling elements (4), and the guide rail (1) and the slider (2) individually have raceway surfaces (11, 21), which form a rolling path (3) of the rolling elements (4), at positions opposite to each other. Then, the rolling elements (4) are disposed in the rolling path (3), and the slider (2) moves with respect to the guide rail (1) via the rolling elements (4). The raceway surface (21) of at least one of the slider (2) and the guide rail (1) is composed of: a first raceway surface (21A); and second raceway surfaces (21B) extending on both sides of the first raceway surface (21), and surface roughness of the second raceway surfaces (21B) is set rougher than surface roughness of the first raceway surface (21A).

    摘要: A bearing comprising a plurality of rolling elements arranged between an inner raceway (12) and an outer raceway (22) of the bearing, whereby a rolling contact interface is defined between a first rolling contact surface (31) on at least one rolling element and a second rolling contact surface formed by one of the inner and outer raceways (12, 22). The first rolling contact surface has a first RMS roughness R
    q1 and has a first roughness pattern y
    i , expressed in terms of the Peklenik number y. The second rolling contact surface has a second RMS roughness R
    q2 and has a second roughness pattern y
    2 . To minimise micropitting in the bearing, the rolling contact interface has a surface topography in which: - the roughness pattern of the first and of the second rolling contact surfaces are oriented in the direction of rolling, whereby γ 1 ≥ 3.0 and Y
    2 ≥ 10.0; and - the first and of the second rolling contact surfaces have substantially equal roughness heights, whereby 0.8 q1 /R
    q2 ≤ 1.25

    摘要: A method of grinding a workpiece with a grinding wheel is provided wherein the shape of the wheel is distorted in a predetermined manner during grinding by changing the speed of rotation of the wheel. This deformation of the wheel during grinding is employed to impart a desired shape to the surface of the workpiece. A grinding wheel is also provided which is asymmetric in side view to adapt it for use in accordance with the method.

    摘要: A manufacturing facility and a super finishing apparatus for ball bearings. The detection part of a matching device (32) is connected to a control means (6) formed of a computer so that detection signals indicating the measured values of the diameters of the outer ring raceway tracks and the inner ring raceway tracks of the ball bearings can be transmitted to the control means. Also, a second grinding device (24) for outer ring, a superfinishing device (25a) for outer ring, a second grinding device (26) for inner ring, and a superfinishing device (28a) for inner ring are connected to the control means (6) so that these devices can receive control signals from the control means. Based on the measured values of the diameters of the outer ring raceway tracks and the inner ring raceway tracks measured by the detection part, the control means (6) provides a shift amount to a diameter machining target value set in the grinding device (24) (or 26) and the super finishing device (25a) (or 28a) for machining the raceway surfaces of the races of at least one of the outer and inner rings.
