IMPROVED LUBRICATION IN TRANSMISSION Russian patent published in 2010 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: invention relates to lubrication of transmission. Improved unit of lubrication contains cover of sun pinion and/or lubricating choke (144). Cover (100) of sun pinion contains structure of cover body, which forms the first opening (108) of lubricant, the second opening (110) of lubricant and channel (112) for passing of lubricant. Passing channel of lubricant implements communication of the first opening of lubricant with the second opening of lubricant. Cover of sun pinion is connected to transmission case so, that the first opening of lubricant is connected to cavity of transmission, and the second opening of lubricant communicates to cavity of pinion. Lubricating choke (144) is movable connected to fixer of thrust washer by means of thrust collar (142), allowing the first part of surface and the second part of surface. Lubricating choke (144) contains the first part of lubricating choke, allowing passing by radius part, movable connected to the second part of surface, and the second part of lubricating choke, forming cavity of lubricating choke, allowing inlet opening of cavity of lubricating choke and one discharge opening of cavity of lubricating choke. Inlet opening of cavity of lubricating choke creates communication of cavity of sun pinion with cavity of lubricating choke, and discharge opening of cavity of lubricating choke is located lengthwise one of radial plane of the second part of lubricating choke.

EFFECT: there is achieved providing of enough lubrication of units of transmission.
