IPC: F16C7/00
Filed: 1989-11-13
Abstract: PURPOSE:To realize relaxation of machining and assembling accuracies in a piston device in which a piston is connected through a piston pin to the small end part of a connecting rod having a large end part and the small end part by using a spherical bearing in at least of the large end part and the small end part. CONSTITUTION:With a piston device, a connecting rod 2 having a large end part 1A and a small end part 3 on its both ends is connected through a piston pin 4 to a piston 5 at the small end part 3. The inside of the large end part 1A loaded with a spherical bearing 6 is spherically machined, the divided journal type bearing is fitted to the inside, and the inside diameter part is fitted to a mating rotary shaft to be formed into a reasonably machined surface. With the piston device incorporated, for example, into a closed type compressor, since the spherical bearing 6 has the degree of freedom in all directions of rotation, the deviation of squareness between a rotary shaft fitted to the inside diameter of the large end part 1A and the center-axis of the inside diameter of a cylinder into which the outside diameter of the piston 5 is fitted, is absorbed, and a relative position of the rotary shaft and the piston can be always traced even in the operation. Relaxation of the accuracies of machining and assembling various parts, stabilized sliding characteristic and starting characteristic can thus be realized.

Abstract: PURPOSE:To suppress the occurrence of inferior image due to long-term use by providing a second surface of curvature which has a smaller radius than that of a first surface of curvature being in contact with a developing roller and forms a developer reservoir between a pressure contact part and the developing roller, on the surface opposite to the developing roller in the pressure contact part of a developer thin layer forming means. CONSTITUTION:A tip 162 has two surfaces of curvature having each central point on the same straight line i.e. a first surface of curvature of a radius R1 to be made in contact with a developing roller 12 and a second surface of curvature of a radius R2 forming a space for toner reservoir between the tip 162 and the developing roller 12. Relation between the radius R1(mm) of the first surface of curvature and the radius R2(mm) of the second surface of curvature is defined within the range satisfying the inequality of R1 >= R2X5. Consequently, an influence of abrasion of the tip 162 on a picture becomes a negligible level.
