摘要： The camshaft serves to control valves in internal combustion engines. It has a shaft (1) and at least one cam (2), which is slipped onto the shaft, is firmly connected to it and has a cut-out (4) to accommodate the shaft. In the region in which the cam is provided, a certain section of the shaft has an enlarged diameter relative to the other regions of the shaft. This region is produced by means of rollers or rolls, all-round beads or webs being formed by displacement of material in the circumferential direction of the shaft. The cam (2) is formed by forging. The cut-out (4) in the cam (2) to accommodate the shaft (1) is widened in the manner of a funnel at least on one side and over at least part of its axial length. The size of the opening of the funnel-like widening (6) corresponds approximately to the radial height of the beads or webs (7). … …

摘要： PROBLEM TO BE SOLVED: To provide a rigid plate connecting method for connecting rigid plates easily without welding or bolt fastening while disjointing them easily to put them back into the state before connection. SOLUTION: Bent parts 2 are provided at one side of two rigid plates 1, and the tip edges of the bent parts 2 are bent at an acute angle onto the rigid plate 1 side to form locking edge parts 3. A bar-like shield member 4 is formed in approximately arrow mark shaped cross section provided with two parallel edge parts 6 projected keeping a clearance from a shield part 5 with an approximately triangular through-hole 5a. Two rigid plates 2 are arranged making the bent parts 2 abut so that the locking edge parts 3 are placed back to back. The locking edge parts 3 are inserted through the through hole 5a of the shield part 5 of the shield member 4, and the bent parts 2 are held in the clearance between. the parallel edge parts 6 to connect two rigid plates 1.

摘要： PROBLEM TO BE SOLVED: To provide the joining structure and method of dissimilar metal materials small in electric resistance and excellent in heat resistance. SOLUTION: A first metal material 1 is made into a sintered alloy by infiltrating a cupper in the clearance between tungsten particles, after mold-pressing and false burning the tungsten particles while adding a very small quantity of additive. The diameter of the tungsten particle in the first metal material 1 is taken as 2 μm-15 μm. The rate of the tungsten in the first metal material 1 is taken as 55 wt.% or more. The cupper which is a jointing material 2 is joined to the cupper tungsten alloy which is the first metal material by a friction press-contact. Thereafter, the carbon steel which is a second metal material 3 is joined to the cupper which is the jointing material 2 by the friction press- contact.

摘要： PROBLEM TO BE SOLVED: To provide a simple, uniform and efficient heating method for shrinkage fastening a fastened member by a bold and a nut, and provide a heating jig that can make assurance doubly sure on securement of work environment and no ill influence on peripheral equipment as to treatment of combustion gas. SOLUTION: Heating combustion gas is led to a heating hole 51 bored on the axis of a bolt, and the inlet side of an exhaust duct 3 with a passage curved in L-shape is detachably fixed to an outlet of the heating hole 51. A jet of combustion gas from the heating hole 51 finished with heating is captured and speed-reduced by an enlarged pipe, and this combustion gas is exhausted in a free direction by a bent pipe curved and rotatable around the axis of the enlarged pipe.
