    摘要： A main spindle device and a method for manufacturing the main spindle device of which a long lifespan is achieved by stably maintaining an amount of grease in a bearing for a long period and increasing the grease lifespan without needing a long running-in time are provided. In a main spindle device (100), outer rings (41 and 21) of roller bearings (40 and 20) include base oil supply holes (47 and 27) penetrating in a radial direction and a housing (103) includes grease paths (133a) to (133e) communicating with the base oil supply holes (47 and 27). Grease is sealed inside bearing spaces of the roller bearings (40 and 20). During running of the main spindle device (100), the grease paths (133a) to (133e) form grease reservoirs.

    摘要： A lubrication system for mutually displaceable bodies of a mechanical device, comprises a porous element and a lubricating liquid (11) comprising dispersed particles (12), the size of the pores (10) of the porous element, and the size of the particles (12) being selected such that the pores (10) of the porous element become blocked by the particles contained in the lubricant liquid film (11) in the area of contact of said porous element with one of the bodies.

    摘要： The disclosure describes a passive lubrication system for use in a high speed print hammer mechanism (10) to provide continuous lubrication to all print hammer elements (12). Channels (22, 23) are formed along the length of a pivot pin (17) and filled with a porous material (24, 25) having a finer porosity than the sintered print hammer block (21) serving as the principal reservoir. Fins (11, 13, 14) located at each side of print hammer elements (12) also are of the same porosity as the print hammer block and communicate lubricant to the material (24, 25) in the pivot pin channels (22, 23). From the channels, lubricant is conveyed to the interface between each print hammer element (12) and the pivot pin by capillary action.

    摘要： The present invention belongs to the field of machinery, more precisely to the field of lubrication of drive chains in machinery such as forestry winches. The invention relates to a spray-based lubrication system for lubricating drive chains of machinery and a forestry winch with the said system. The lubrication system comprises:
    - at least one attachment arranged to receive a lubrication spray or container of the lubrication spray, wherein the said attachment comprises:
    o a base body having:
    ▪ an opening arranged to receive a part of the lubrication spray,
    ▪ a central bore for connection with the lubrication spray,

    o an outlet tube with preferred protrusions arranged to reliably hold the supply tube of the lubrication system,

    - preferably at least one lubrication spray, which may be provided separately from the system according to the invention, and
    - at least one supply tube, which is on one of its ends connected to the said attachment and is on the other end preferably provided with a lubrication brush for leading the lubrication agent from the spray inserted in the said attachment to the drive chain(s).
