    摘要： The invention relates to a lubrication system for a mechanism (27), on-board a spacecraft. It comprises a non pressurized tank (20) communicating with the mechanism (27) via a tube (220). A piston (23) closes the tube (220) while the mechanism is at rest. The piston (23) is controlled by a first spring (5) and by a second, shape memory, spring (24) opposing the latter, which lengthen by thermal effect. A controller (25, 26) supplies this spring with a current (I) to actuate it. An annular element(7), pushed by a cylindrical spring (6), defines a capillarity filled pumping chamber (22). When the temperature of the shape memory alloy (24) falls back below a threshold, the spring (24) recovers its original shape, the first spring (5) pushes back the piston (23) and expels a dose of lubrication fluid (4).

    摘要： The embodiment of the invention disclosed is a conveyor roll having a cylindrical shell with integral end caps and axial sleeves extending inwardly from the end caps. The shell, end caps and sleeves are rotatably journalled about the shaft by roller bearings between the sleeves and the shaft. An internal labyrinth is provided in each sleeve between the bearing and the end of the shell, this internal labyrinth including a rotatable collar and a non-rotatable bushing carried respectively by the shell and shaft and having a series of facing cylindrical and annular surfaces providing a labyrinthine passageway of restricted cross-section extending from the bearing means to an annular outlet at the end of the shell. An external labyrinth is provided outside the end cap. This includes first and second annular flanges carried respectively by the shaft and shell and axially spaced from the annular outlet and from one another. These two flanges provide inner and outer radial passages. The outer radial passage has radial and axial dimension exceeding those of the inner radial passage whereby centrifugal force acting on a radial column of lubricant in the outer radial passage opposes leakage from the shell.

    摘要： A lubrication system is described for a motor having a substantially vertical spindle with a bearing toward the upper end thereof. Lubricant is carried to the bearing through an axial passage in the spindle and the design is such that most of the lubricant is by-passed from the bearing and returned to the reservoir so that a substantially greater flow of lubricant than that necessary to lubricate the bearing is provided, thereby cooling the spindle.
