Abstract

The invention provides a lubricated taper roller bearing assembly comprising a taper roller bearing 14 arranged in series with a screw pump 17, said bearing 14 and screw pump 17 in use being submersed in lubricant, said screw pump 17 being rotatable in unison with one of the inner and outer bearing rings which is rotatable relative to the general body of lubricant contained in a lubricant sump, and said screw pump 17 being positioned axially at that side of the taper roller bearing 14 at which the bearing rollers have their maximum diameter. Preferably said screw pump 17 is arranged to urge lubricant to flow in a directional way from the taper roller bearing. The invention also provides a gear unit which is for operation in either of two direction of rotation, wherein two pumps (65,66, Fig 8) may be provided and arranged such that one provides forced lubrication when drive in one direction and the other provides forced lubrication when drive is on the opposite direction.
