Abstract: The invention relates to a compact seal packing (10), ensuring dynamic sealing between a rotary shaft and a stationary body, in particular a stationary enclosure. In particular, the seal packing (10) comprises a compression spring (16) bearing against a transmission element (18) to transmit the forces of the spring to a friction ring (12) and press it against a counter-ring (14). The compression spring (16) is bearing against a first radial flange (181) of the transmission element (18), a second flange (182) of the transmission element (18) being located partially facing a radial surface (122) of the friction ring distant from the counter-ring (14) and a cylindrical wall (180) of the transmission element (18) being located partially facing the cylindrical outer surface (124) of the friction ring (12).

Abstract: A liquid pump comprising a motor housing, a motor, a volute housing joined to the motor housing, and upper and lower seals contained in the volute housing. The motor housing has a motor housing side wall including a distal end joined to the volute housing. The motor includes a rotatable shaft that extends into the volute housing. The volute housing includes an upper volute wall having a major portion in direct fluid communication with the motor housing volume, thereby enabling a high rate of heat transfer from the motor to the fluid in the volute that is being pumped. In that manner, the pump has dual seal capability that reduces the risk of motor damage due to a seal failure, while also having a high rate of heat transfer out of the motor housing, which reduces the risk of failure of the motor from operating at a high temperature.

Abstract: A viscous fluid reaction apparatus is described. The viscous fluid reaction apparatus comprises a glass reaction vessel. The viscous fluid reaction apparatus further comprises a gas-tight inlet assembly and a gas-tight stirrer assembly. The gas-tight stirrer assembly comprises a stirrer opening adapter, a stirrer coupling comprising a stirrer shaft seal connected to the stirrer opening adapter, a stirrer shaft comprising one or more stirrer blades located at a blade end of the stirrer shaft, and a motor coupling connected to the stirrer shaft. The viscous fluid reaction apparatus further comprises a motor connected to the motor coupling. The stirrer shaft passes through the stirrer coupling and the stirrer opening adapter such that the stirrer blade(s) are disposed in the glass reaction vessel at a blade height and the stirrer shaft is configured to rotate without compromising a gas-tight seal formed by the stirrer shaft seal.

Abstract: Aspects of the disclosure can relate to an apparatus including a first member having a first bearing surface formed from a hard material (e.g., a diamond-based material, such as a polycrystalline diamond material), and a second member coupled to an input shaft to translate (e.g., rotate, slide, etc.) with respect to the first member. The second member has a second bearing surface formed from a hard material, and the second bearing surface is to bear against the first bearing surface. In embodiments of the disclosure, the first and second members can be for devices including, but not necessarily limited to: solenoids, generators and/or motors (e.g., out-runner radial flux generators, axial flux generators, radial flux generators/motors, roller vane motors, etc.), gearboxes, rotary data swivels, digital actuators, filters (e.g., inner rotating filters), valves (e.g., proportional valves), sensors (e.g., pressure differential sensors), and so forth.

Abstract: This bush is made out of a composite material that has a modulus of elasticity of between 500 and 6000 N/mm2, said bush having at least one lip formed directly at the time of manufacture as an overrun edge of its bore to act as a leak-tight or protective barrier after mounting on the shaft by creating a tightening effect between the inside diameter of said lip or said lips, and the outside diameter of said shaft.

Abstract: A hydraulically adjustable cone crusher and a axial bearing assembly of a cone crusher, which crusher comprises an hydraulic adjustment cylinder/piston assembly mounted in the space formed between the crushing head and the upper surface of the main shaft for adjusting the setting of the crusher. The pressure medium of the hydraulic adjustment system of the crusher is supplied to the pressure medium space formed, except by the adjustment cylinder/piston assembly, also by at least one bearing element.

Abstract: An improved bearing assembly for mounting a drive shaft and bearings, having an upper impeller drive shaft for the tailings conveyor of a combine harvester occupy the same space as the cleaning system rail and seal of a chaffer sieve, is disclosed. The assembly has a flush mounted bearing at one end of the shaft and a normal bearing and lock collar at the shaft's opposite end.

Abstract: The disclosure is directed to a bearing and seal assembly apparatus for a endless chain drive for trenchers. The disclosure is particularly directed to the use of such an apparatus in trenchers used in rock or hard packed soils. The apparatus of the present invention uses bearing and seal assemblies that prolong the useful life of the gear box, the drive assembly and ultimately the trencher as a whole.

Abstract: A dynamoelectric machine or electric motor construction is disclosed in which the motor has a cylindrical shell having a stator core press-fitted therein and positioned axially with respect to the shell at a predetermined position. The stator core has a central bore which rotatably receives a rotor assembly, the latter having a rotor shaft extending outwardly from each end thereof. An end shield is press-fitted into each end of the cylindrical shell to a predetermined axial position thereby to support bearings journaling the rotor shaft, with the rotor shaft extending axially outwardly through one of the end shields for connection to its application. This one end shield has a seal which is maintained in perpendicular relation to the rotor shaft and which slidingly seals the interior of the motor relative to the end shield and to the rotary application and rotor shaft.
