A cone piece is tightened into a compatibly shaped hole in the end of a shaft. As the cone piece is tightened, it forces the shaft to expand outwards. As the shaft expands, it creates or increases pressure against a hub, wheel, crank or other mating piece that is positioned on the shaft, locking it into place.

A gas turbine engine casing apparatus includes annular first and second annular cases connected by a spigot joint. The spigot joint includes an annular projection of the first annular case fitted into an annular recess of the second annular case. A plurality of circumferentially spaced apart scallops are formed on one of surfaces of the annular projection or of the annular recess, and are located in selective circumferential locations adjacent respective enhanced stiff areas of the first and second annular cases.

This invention uses disc shaped cams in enlarged hoes in machine feet to allow a machine to be moved and properly installed to the bedplate. Once the machine is in the proper location, the cams are locked into place with a set screw which prevents the cams from rotating and the machine from moving. The machine foot is then secured to the base by a washer and the manufacturer's specified anchor bolt is torqued to the proper value.

A connecting structure, which is located between a first object and a second object, includes a first engaging member and a second engaging member located between the first engaging member and the first object. The first engaging member is located between the second engaging member and the second object. The second engaging member has a thickness. When a distance between the first engaging member and the first object is less than or equal to said thickness, the first engaging member and the second engaging member are not movable relative to each other. When said distance is greater than said thickness, the first engaging member and the second engaging member can be moved in a direction relative to each other, moving the first object and the second object relative to each other as well. A covering device for an opening of a building is also disclosed, which includes said connecting structure.

The described embodiments provide a subsea connector that is a quickly deployable and reusable. The subsea connector comprises a male and a female assembly that can be connected and disconnected. The male assembly includes a shaft, a sleeve that surrounds the shaft, and bars that are connected to the shaft and are configured to rotate about one axis. The female assembly includes a receptacle into which the male assembly can fit. Once the male assembly is inserted into the female assembly, the bars can rotate into such a position that the male and female assemblies are connected together. The bars can also be rotated such that the male and female assemblies can be disconnected.

An apparatus is provided for connecting a rotary shaft to a rotatable machine element. The apparatus includes and inner sleeve for clamping onto the shaft and an outer sleeve for clamping onto the machine element. The inner and outer sleeves have cooperating tapered surfaces for tightening the apparatus. The cooperating tapered surfaces include striations. A nut connected with the inner and outer sleeves is rotatable to drive the inner sleeve relative to the outer sleeve in a first direction to tighten the inner sleeve onto the shaft and the outer sleeve onto the machine element. A method is also provided for forming a mounting device for connecting a machine element with a rotary shaft.

A linear drive assembly having a linear drive motor having a shaft, the shaft defining a first bore therein extending from the first end of the shaft, the shaft defining a tapering within the first bore, and the shaft defining a second bore therein connected with the first bore and extending to the second end of the shaft; a screw including a tapered end at the first end of the screw, the tapered end configured to substantially mate with the tapering within the bore, and the screw defining a threaded bore extending from the tapered end at least partially along a longitudinal axis of the screw; and a retaining screw having a head portion and a threaded portion, the threaded portion configured to extend through the second bore and mate with a threaded bore of the screw when the screw is mounted within the shaft.
