Title: Annular body fitting device
Inventor: TAKADA HIROTOSHI
IPC: F16C35/073
Filed: 1991-03-08
Abstract: PURPOSE:To prevent breakage of an annular body due to thermal fluctuation upon usage so as to effectively transmit load in the case where linear expansion coeffients of a mating member and an annular body fitted to the mating member are different. CONSTITUTION:In a cylindrical roller bearing where a ceramic inner ring (annular body) 20 is assembled with a steel shaft (mating member) 10, cylindrical parts 40b of a pair of spaced seats 40 fitted to the shaft 10 firmly is fitted to the outer circumferential face of the inner ring 20. The spaced seats 40 are made of spring steel member and thin in their cylindrical parts 40b, and are provided with cut part 41 which supports the inner ring 20 with respect to the shaft 10, resiliently in the radial direction. Fluctuation of margin, that is generated caused by thermal stress generated at the fitting faces 23, 43 of the inner ring 20 and the spaced seats 40 due to temperature fluctuation during usage of such a bearing as constituted in the above, is alleviated and absorbed. The load on the inner ring 20 is therefore transmitted to the shaft 10 via the spaced seats 40 without breakage in the inner ring.

Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve product yield by sticking photosensitive transfer layers on sections except sections not requiring laminating, laminating the layers accurately without creases at high speed and eliminating the necessity of cutting a cover film and a base film. SOLUTION: A continuous laminated film 1 is unwound from a film unwinding section 2 and guided to an inter-base processing section 3.

The film passed through the inter-base processing is taken up by a cover take-up machine 4 through a cover film release guide 15. After the film is passed through an accumulating roll, the film is transferred to a laminating roll. The position of the base is controlled, and the position is so registered as to conform sections not requiring laminating to the inter-base processed film sections. The photosensitive transfer layers can be laminated continuously at high speed and without the unevenness of the thickness by the arrangement.
