medium-sized bearings

Large timken backing bearings mounting force required to increase significantly , and should use hydraulic nut and / or using the oiling method :
( 1) When using a hydraulic nut mounting the bearings, it must be positioned on the threaded portion of the journal or a threaded sleeve , so that the annular piston against the bearing inner ring , the shaft nut or ring mounted on the shaft end . Through the oil pump oil into the hydraulic nut to secure , install the required precision of the force, the piston moves in the axial direction . Using hydraulic nuts, spherical roller bearings installed

( 2 ) using the oiling method , oil is injected under high pressure between timken bearing and journal , forming a layer of film . This layer of film will be separated with the surface , significantly reduces the friction between the mating surfaces . Directly mounted to the bearing cone journal , generally use this method, but is also used in France to prepare for oiling tight sets and shift put mounting bearings. Or lubricator pump generates the necessary pressure on the shaft or sleeve grooves and the oil channel , between the mating surfaces of the oil injection . When designing the bearing arrangement , the necessary arrangements must be considered a groove on the shaft and the channel . Spherical roller lysn-bearing with a tank mounted on a withdrawal sleeve , through the oil into the mating surface , and in turn tighten the screws Withdrawal sleeve pressed into the bearing bore .
