Title: Valve timing regulator for internal combustion engine
Inventor: MORII YASUSHI
IPC: F01L1/34
Filed: 1991-11-11
Abstract: PURPOSE:To prevent generation of beat during operation of a valve timing regulator for an internal combustion engine by providing a rotation preventing member for connecting an eccentricity absorbing member to a housing for impossible rotation while free motion in the axial direction. CONSTITUTION:A phase changing member 7 interposed between a sprocket 2 and a camshaft 1 is moved in the axial direction by a shaft 17 of a ball screw, for changing a valve timing. The shaft 17 is supported by a nut 18, is prevented from being rotated by a rotation preventing mechanism 14, and is moved in the axial direction according to the rotation of the nut 18. The rotation preventing mechanism 14 is provided with a sleeve 14a fixed onto the outer periphery at the end of the shaft 17 by a pin 14b. A key 14c attached onto the outer periphery of the sleeve 14a is fitted to a key way 12c of a housing 12. Since the sleeve 14a can be moved perpendicularly to an axis along the pin 14b, eccentricity of the shaft 17 with respect to the housing 12 can be absorbed. It is unnecessary to form a clearance between the key 14c and the side wall of the key way 12c, where no beat is generated.

Abstract: PURPOSE:To miniaturize and lighten an arm by mutually connecting a gear fixed to a main post and that installed on a 1st fixed axis, a gear fixed to the 1st fixed axis and that installed on a 2nd fixed axis respectively by power transmission devices of toothed belts, etc. CONSTITUTION:A driving axis 5 is rotated on driving of a telescopic arm motor 6 and the 1st arm 4 linked integrally with the axis 5 is rotated by a rotation angle phi to a main post 1. Since a gear 3 fixed to the main post 1 is therefore rotated by the rotation angle phi relatively to the 1st arm 4, a gear 9 is rotated via a toothed belt 11 with this rotation. At this time, the rotation angle of the gear 9 becomes -2phi, provided the tooth number ratio of the gears 3 and 9 be taken at 2:1 and so the rotation angle of a 2nd arm 10 becomes -2phi as well. Consequently, the rotating axis of a gear 13 is moved only in a radial direction R by equalizing the interaxis distance l1 of the gears 3 and 9 and that l2 of the gears 8 and 13.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of solder balls due to the positional drift between the solder balls of an inspected body and inspecting electrodes and to make a reliable electrical connection by separately forming an inspecting electrode board and a wiring layer board, and fixing them into an integrated structure via an adhesive layer.
