【Abstract】 A computing formula of normal backtash is derived for profile shifted gear driving by centre distance changing bigger. Its influence guantity to normal backlash is analysed by example. The relation of normal backlash, pressure angle and deflection coefficient for designers reference are derived.更多还原
