Abstract: A construction for clamping together a first member and a second member. The first member is formed with a bolt hole, and is in contact with the second member which is formed with an elongated slot.

A block member lying within the elongated slot is formed with a hole through which the shank portion of the bolt passes. The head of the bolt presses the block member into the slot, towards the first member. The side walls of the block member are in contact with the side walls of the slot. At least one of the side walls of the block member or of the slot angles inwards, and the block member is so thick in the direction across the slot that without deformation of the parts the block member cannot be pulled by the bolt so far through the slot towards the first member as to contact the first member.

Fasteners extend through the bores in directions parallel to the axes of the shafts or tubes. The fasteners are radially expandable into clamped conditions in which they abut and exert radial pressure against the bores in the flanges. This eliminates the play between the two adjoining flanges, which play stems from necessary initial clearances between the fasteners and bores to allow for insertion of the fasteners into the bores.

Abstract: The invention refers to a method for interconnecting two flange-provided shaft ends by means of taper pin bolts and expander sleeves co-operating therewith as well as a shaft coupling assembled accordingly. The shaft coupling is intended to transfer very large torques and great bending stresses, e.g. in steam and nuclear power plants. The new shaft coupling and the mounting method enable the use of the same bolt as an expansion-shell bolt, for achieving the desired press fit, and as a set bolt, which can be pre-loaded to function like a hard-tightened fitting bolt. This has been achieved on one hand by preventing the expander sleeve from moving axially, when the bolt is tightened, and on the other hand by abolishing the friction between the sleeve and the bolt after achieving the desired press fit, whereupon the bolt is further tightened up close to the yield point of the bolt. In this position the bolt is fixed by means of the nut so that the bolt preserves the desired press fit as well as the pre-load.

Abstract: A flexible shaft coupling wherein the flange of at least one of the shafts is flexible and its marginal portion is separably fastened to the marginal portion of the other flange. The flanges surround thrust transmitting elements which are urged against each other as a result of deformation of the flexible flange in response to fastening to the other flange. The flexible flange may be integral with or it may be separably fastened to the shank of the respective shaft. The flexibility of the coupling is enhanced if the flexible flange is provided with or mounted between knife edges which permit such flange to snap over in response to tilting of one shaft with respect to the other shaft and/or vice versa. The thrust transmitting elements may be integral with the respective shafts or they may constitute removable inserts. One of the thrust transmitting elements has a convex face which bears against a flat face of the other element so that the elements are in mere point contact with each other.
