Abstract: PURPOSE:To easily measure the backlash of a gear at a plurality of places. CONSTITUTION:The respective chucks 190, 270 of a moment imparting device 80 and an angle detector 82 slightly fall from the axial line of a first balance shaft 24 by the descent of a lift table 56 and, after the first balance shaft 24 is grasped, a lift table 130 descends with respect to the lift table 56 and shaking plates 174, 264 become a shakable state. A wt. is alternately placed on both end parts of the shaking plate 174 in such a state that a crank shaft is fixed by a fixing device and the displacement of a detection body 300 accompanied by the revolution of the shaking plate 264 at this time is detected by a magnet scale 304 to calculate backlash. A gear is rotated by rotating the crank shaft by a rotary driver and the backlash of the gear is measured at a plurality of places.

Abstract: PURPOSE:To improve the precision in setting the valve timing by connecting the both cam shafts by helical gears and installing shims on the both sides, keeping the bearing on one cam shaft interposed, in an engine in which two cam shafts are installed in the top part. CONSTITUTION:Two cam shaft 2 and 3 installed over a cylinder are connected through helical gears 6 and 7. A flange 3b is installed, keeping a prescribed interval for a bearing 1d installed at the edge part of one cam shaft. Shims 12 and 13 are installed between the flange 3b and the edge part of the bearing 1d. In order to prevent the revolution phase of the cam shaft on the driven side from being varied by the deflection in the lateral direction of the helical gears 6 and 7, each thickness d1, d2 of the both shims 12 and 13 is selected so that the revolution phase of the cam shaft 3 on the driven side is made proper.

Abstract: PROBLEM TO BE SOLVED: To prevent unbalance from being generated even when a quill body is replaced, in a spindle device in which the diameter to be machined is changed by means of a quill body which is off-centered from the spindle. SOLUTION: A spindle 10 journaled to a housing 16 supports a recess shaft 20 so that it can freely rotate around the eccentric axis of rotation. A quill body 55 containing the weights of mounted tools 58a, 58b and balanced around the axis of rotation, is coaxially and integrally connected to the recess shaft through a clamping mechanism 30. A balance weight 60 relatively rotatably mounted to the quill body and constituting a tool holder 50 together with the quill body, is connected to the spindle 10 by a rotation regulating member 62a, and has the unbalance quantity by which the center of gravity of the whole of the tool holder is allowed to coincide with the axis of rotation of the spindle in state where the balance weight is mounted to the spindle 10.

Abstract: PURPOSE:To judge the presence or absence of the biting between a socket and a screw without lifting a work after the screw is tightened by the.socket in the work. CONSTITUTION:A screw tightening device 4 tightens a screw into a work W by fitting a socket 5 to the screw and rotating it by a rotary shaft 18a of an electric motor 18. The device 4 is provided with a first cylinder 12 to integratedly move the socket 5 and the rotary shaft 18a to the position approaching to the work W arranged therebelow and the position away upward from the work W. The socket 5 is connected to the rotary shaft 18a in an integratedly rotatable and relatively movable manner through a spindle 22. The socket 5 and the spindle 22 are relatively movable to the rotary shaft 18a by a second cylinder 17. The value of the moving force to be given to the socket 5 and the spindle 22 by the second cylinder 17 is set to be smaller than the gravity value of the work W.

Abstract: PURPOSE:To make it possible to process the end surface of a cam thrust face of a cam shaft accurately and smoothly, by combining a chamfering process of a curved surface with a lathing and a finishing process of a cam thrust face with a grinding. CONSTITUTION:At first, the end surface 522 of a cam thrust face 52 is chamfered in a curved surface by a lathe grinding, and them the cam thrust face 52 is finishing-processed by a grinding process. In this case, since minute burrs 524 are produced at the end surface 522 of the cam thrust face 52, the burrs are removed to make the end surface 522 in a smooth curve by using a honing grindstone 2, and the cam thrust face 52 of the cam shaft 50 is chamfered. In such a way, the end surface of the cam thrust face can processed accurately and smoothly, and a damage of a cylinder head when the cam shaft is installed can be prevented.

Abstract: PURPOSE:To perform an alignment job ever so easy, by marking two points on each gear at the time of setting these gear driving each cam for both suction and exhaust valves, and first adjusting the first point, then setting these gears as being rotated, while making sure of the second point being congruous with the former after setting. CONSTITUTION:A gear 10 for an intake cam shaft 6 is rotated by a crankshaft 5 via a timing belt 12, whereby an exhaust cam shaft 11 to be engaged with the gear 10 rotates, and the intake cam 6 and an exhaust cam 7 both rotate at the specified relation with the crankshaft 5. At the setting a gear 11, first points 19 and 20 of these gears 10 and 11 are accorded with each other, having them engaged with each other, and the gear 10 is rotated whereby it is fitted in a cam shaft 16 and locked thereto. At this time, making sure of second points 21 and 22 of these gears 10 and 11 being congruous with each other, whereby a fact that their alignment is properly carried out is checked.
