Title: Thrust bearing structure of planetary gear
Inventor: MORIKAWA KUNIHIKO
IPC: F16C17/04
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a thrust bearing structure of a planetary gear, to enhance thrust supporting rigidity of a needle bearing, and to heighten resistance to friction in a thrust washer. SOLUTION: A pinion 1 of a planetary gear is supported by a pinion shaft 6, which is fixedly supported by both side carrier plates 4a and 4b. A thrust ring 7 has an outside diameter smaller than an inside peripheral diameter of the pinion 1 and larger than a center diameter of a needle bearing 5, and is made of steel undergoing quenching treatment. This thrust ring 7 is affixed to the both side carrier plates 4a and 4b by press fitting or casting. In order to support the pinion 1 being thrust against the carrier plates 4a and 4b, the thrust washer 8 located therebetween is press-fitted into the thrust ring 7. Thus the steel thrust ring 7 receives a skew thrust force of the needle bearing 5 to exert no effect on the thrust washer 8.  As a result, the frictional resistance between the thrust washer 8 and an end face of the pinion 1 is reduced to increase resistance to friction in the thrust washer 8.

Abstract: PROBLEM TO BE SOLVED: To simplify and speed up a detection routine, to decrease the failures in detection and to enhance the reliability of this apparatus by extracting a pupil edge part from an eyeball image, determining a pupil central position, calculating the rotating quantity of the eyeball by using the data of a predetermined Purkinye's image and determining the visual line direction. SOLUTION: When the eyeball 5 is irradiated with the light from an IRED 7, the virtual image of the IRED 7, i.e., the Purkinye's image, is formed on the cornea 10. The relative positions of the pupil center and the Purkinye's image are changed by accompanying the rotation of the eyeball 5, and the rotating direction of the eyeball 5 is detected by calculating the relative positions. The image of the eyeball is reflected to the upper part by a dichroic mirror 6 arranged at 45 deg. with the optical axis of the eyeball and is formed on an image pickup image 8 by an image forming lens 9, by which the image of the eyeball 5 is captured. The eyeball image is subjected to point extraction of the edge part of the pupil forming an approximately circular shape from the eyeball image and is subjected to circular approximation.  Since the relative displacement quantity of the central point of the calculated circle and the Purkinye's image is the rotating quantity of the eyeball, the detection of the visual line direction may be executed.
