About the shaft bearing of the original radial clearance

About shaft bearing of the original radial clearance in theory, when there is a slight negative clearance, bearing life can be extended. Such ambition, however, is difficult, and it's too big negative clearance will greatly shorten the life of bearing. Therefore, the general should use zero clearance or subtle positive clearance rather than negative clearance. In choosing a water pump shaft bearing initial radial clearance, in addition to thinking because of the outer ring and bearing hole cooperation due to the clearance volume reduction, but also thinking because the result of the related components heat and temperature lead to a drop in the amount of clearance, the pump shell has two kinds of aluminum and iron shell. Axis even bearing the cooperation with shell generally take the surplus cooperation, introduce interference quantity such as table 1, because even the pump shaft bearing axis and shell of the temperature difference is bigger, the minimum clearance requirements can pass the budget work out, but in most cases is achieved through test results and application experience.
