摘要： A main shaft fixture for fixing a main shaft on a wind turbine during installation and repair work on heavy parts of the wind turbine nacelle, in the case where the fixture is formed of several sections for mounting on stable structural parts in the nacelle, including the nacelle's bottom frame. The main shaft fixture has adjustable pressure mandrels with tap shoes, which cause the fixture to be usable regardless of the turbine main shaft geometry, such that it can be mounted without fixing the rotor. The main shaft fixture also has facilities for mounting of a lightweight crane and a self-hoisting crane with a ground-based winch, respectively, as well as a rotor lock which, in combination with actuators of the main shaft fixture, enables the main shaft and the main shaft bearing to be sufficiently displaced vertically from its bearing in the nacelle to service or replace the bearing.

摘要： A work holder assembly for use in clamping a workpiece being machined. A chuck includes a fixed sleeve about which is mounted a rotatable collet. A plurality of individual clamps extend from circumferential spaced locations associated with the collet. The clamps each include a first spring biased and linear traveling component actuating a second radially traveling and adjustable component into engagement with annular disposed locations of the workpiece. Each the clamps exhibits a wedge shape at an interface between the linear and radial components, both in order to minimize clamping forces and to prevent backdriving of the clamps by the tooling. A fluid pressure extends through a location in the chuck, the collet further having a fluid delivery component in communication with the fluid supply and which is in contact with workpiece engaging locations, to overcome the spring bias of said pin in a fluid actuated release condition.

摘要： The invention relates to a clamping device, especially for releasably clamping a machine tool having a fixing element extending therefrom. The clamping device includes a deforming clamping element which acts on a clamping part with a clamping force in order to secure the fixing element to the clamping device. The deforming clamping element may also be controlled to act on the clamping part with a releasing force in order to release the fixing element from the clamping device. Both the clamping force and the releasing force result from the deformation of the deforming clamping element.

摘要： A chuck actuator has a hollow housing having a chamber and having a front end and a rear end. A ring in the chamber forms with the front end thereof a front compartment and a piston in the chamber between the ring and the rear end forms an intermediate compartment with the ring and a rear compartment with the rear end. A stem on the piston projecting forward through the ring and through the intermediate and front compartments is adapted to engage and open a chuck and is formed with a region of enlarged diameter. The piston is shiftable between a rear position with the enlarged-diameter region offset rearward from the ring and with the stem forming with the ring an axially extending passage between the front and intermediate compartments and a front position with the enlarged-diameter portion fitting snugly in the ring and substantially closing the passage.
