Therefore, please fully study the installation of the bearings that carried out in accordance with the operating standards including the following items, please bearing installation.
The following provides several bearing installation method.
1.
Force fit bearing inner ring and shaft tight fit and available press the bearing pressure equipment in the shaft first, then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal materials (
Copper or mild steel)
, the inner diameter of the casing assembly should be slightly larger than the diameter of a journal, outside diameter than the bearing inner ring guard slightly smaller, in order to avoid pressure in keeping the frame.
2.
Heating with this method is suitable for interference quantity larger the installation of the bearing, the bearing before hot charging type or separable bearing ring into the fuel tank 80 - uniform heat
100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and shoulder joint is not tight, bearing axial fastening again after cooling.
