Abstract: A clamping device includes a base body defining at least a portion of at least one pressure chamber, which has at least one opening oriented in a direction of action. A membrane is connected with the base body in a pressure-tight manner and seals the at least one opening in the direction of action. The membrane defines a first side wall section of the pressure chamber. A movable second side wall section partially delimits the pressure chamber and a constant amount of pressure fluid is sealed in the pressure chamber. At least one mechanical actuator displaces or deforms the second side wall section in order to cause the membrane to outwardly bulge.

Abstract: A system for providing a load on a bearing mounted to a shaft includes an attaching member releasably connectable to the shaft and a press mechanism in fluid communication with a source of fluid and configured to provide a compressive load to the bearing. The press mechanism includes a switch having a base and a piston in communication with the fluid such that an increase in a pressure of the fluid results in the piston extending upwardly from the base and a decrease in the pressure of the fluid results in the piston retracting toward the base. The switch includes a lower proximity sensor and a higher proximity sensor. The piston is configured to extend upwardly from the base past the lower proximity sensor and to trip the higher proximity sensor. The switch is configured to control the increase in the pressure in response to the piston tripping the higher proximity sensor.

Abstract: An apparatus for preloading a bearing assembly on a shaft includes a first annular threaded member positioned about the shaft and a second annular threaded member positioned about the shaft. The first and second threaded members have intermeshing threads such that rotation of the second threaded member causes axial translation of the first threaded member to apply a first axial force to the bearing assembly to preload the bearing assembly. An actuator is operable to rotate the second threaded member relative to the first threaded member to apply the first axial force to the bearing assembly.

Abstract: A system is disclosed for mounting a bearing assembly in the stern-post of ships in order to minimize wear between the outer ring of the bearing assembly and a bearing seat and where the inner ring is mounted on a propeller shaft. The system comprises two axially spaced pressure chambers interconnected by a conduit and adjacent opposite axial ends of the outer ring, a hydraulically operable piston in each of the chambers, a pump for pressurizing the chambers, and pressure valves in the conduit for limiting the fluid flow between the chambers and operable to permit fluid flow between the chambers-to balance the pressure in the chambers when the pressure in either chamber exceeds a predetermined level.

Abstract: The invention relates to a device and a method for mounting a bearing 200 on a roll neck and for removing the bearing from the roll neck of a roll. Known devices of this type have a first and a second piston/cylinder unit. They also have a stop ring 130, fixed in the axial direction A at the end of the roll neck 320 remote from the body, which acts as a stop for the inner piston 110 of the first piston/cylinder unit. In addition, the known devices have a nut 150 which can be screwed onto an external thread of the inner piston to secure the bearing 200 in the axial direction, in particular during a rolling operation. As an alternative to the known prior art, the present invention provides that an annular cylinder 120 serves both as a cylinder for the first piston/cylinder unit and as a cylinder for the second piston/cylinder unit. For its function as a cylinder for the second piston/cylinder unit, said annular cylinder is covered to a certain ex ent on its side remote from the body by an annular cylinder cover 122. The cylinder cover 122 serves, together with an outer flange 142 of an outer piston 140, to axially delimit a removal pressure chamber 2 of the second piston/cylinder unit.

Abstract: A method and device for establishing the correct amount that a bearing should be driven up a shaft involves measuring the strain on at least one of the side faces of the bearing ring through use of a sensor arranged on the side face of the bearing ring. The strain is measured while the bearing is being driven or moved along the shaft. The instantaneous bearing internal clearance reduction in the bearing can then be calculated from the measured instantaneous strain and the value for the known initial bearing internal clearance of the bearing.
