摘要:
A combined bearing assembly comprises a thrust bearing receiving a thrust load with a number of rollers interposed between a planar inner member and a planar outer member, a radial bearing consisting of a radial receiving member secured to the inside diameter of a radial flange, the outer peripheral edge portion of the outer member having an outer flange formed by being axially bent, and a restraining member of L-shaped cross section fitted to the outer flange. The inside diameter dimension of the restraining portion of the restraining member is smaller than the outside diameter dimension of the inner member. The inner member and the outer member are prevented from being separated from each other.

The cage includes two interconnected members. Each member has a plurality of circumferentially spaced openings; the openings in one member aligned with and spaced from the openings in the other member to form pockets for rollers.A portion of each long side of the openings is adapted to retain the rollers. Each interconnected member has tongues adjacent the openings. The tongues extend toward the other member with the tongues on one interconnected member facing and circumferentially spaced from the tongues on the other interconnected member. The spacing between the tongues in each pocket is chosen so that the tongues act as guide surfaces for the rollers.

A main object of the present claimed invention is to provide a scanning probe microscope that can recognize a relative position between multiple probes accurately. The scanning probe microscope comprises multiple probes 21, 22, 23, 24 movable in the XYZ-directions, a stage 3 on which a specimen W is placed and that is movable in the XY-directions, a detecting part 6 that detects the physical properties that changes with the movements of each of the probes 21, 22, 23, 24 in the Z-direction according to the surface shape of the specimen W, at a time when each of the probes 21, 22, 23, 24 or the stage 3 is moved in the XY-directions, an image generating part 73 that images the surface image of the specimen W in response to the detected signals from the detecting part 6, and a relative position calculating part 75 that obtains the surface image based on each of the probes 21, 22, 23, 24 and obtained by the image generating part 73, when the stage 3 is moved in the XY-directions without changing a relative position between the probes 21, 22, 23 24 in the XY-directions, and calculates the relative position between the probes 21, 22, 23, 24 by checking the surface images obtained by the probes.

摘要:
A combined bearing having both a radial bearing and a thrust bearing which is applicable to the strut-type suspension of an automotive vehicle. The combined bearing includes a bearing race member having a sealing capacity which is coupled to an opposing bearing race member by using an engaging lip and a coupling lip. Both lips are provided on a radial bearing member. The outside configuration of the assembled sealed combined bearing is compact. In addition the construction, handling and assembly are very simple.

In the toroidal-type continuously variable transmission, the radial needle roller bearing includes a plurality of needle rollers, the two end portions of each of the needle rollers in the axial direction thereof are crowned, and the crowning amount is set such that, in the portion of the needle roller that is situated by 7-13% of the axial-direction length toward the axial-direction central portion of the needle roller from the axial-direction end face of the needle roller, the crowning amount is 0.1-0.4% of the outside diameter of the axial-direction central portion of the needle roller. Further, in the inner peripheral surface of the output-side disk, there are formed a fitting portion to be fitted outside with a member rotatable in conjunction with the output-side disk and an outer race raceway portion for the needle roller bearing, in the portion of the inner peripheral surface of the output-side disk that is situated near to the inside surface thereof, there is formed a residual compressive stress layer by shot peening, and the outer race raceway portion is ground so as to remove a portion of the residual compressive stress layer, to thereby form the outer race raceway portion as a smooth surface.
