straight bevel gear การใช้

• For these reasons straight bevel gears are generally limited to use at linear speeds less than 1000 feet / min; or, for small gears, under 1000 r . p . m.
• With straight bevel gears, the abrupt tooth engagement causes noise, especially at high speeds, and impact stress on the teeth which makes them unable to take heavy loads at high speeds without breaking.
• In spur gears and straight bevel gears, tooth profiles are considered only in a transverse plane, and the general terms profile angle and pressure angle are customarily used rather than transverse profile angle and transverse pressure angle.
