With straight bevel gears, the abrupt tooth engagement prospects to appears, especially at higher speeds, and impact pressure on the tooth which can make them not able to contemplate hefty hundreds at large speeds with no breaking. For these leads to straight bevel gears are normally constrained to use at linear speeds drastically considerably less than 1000 toes/min or, for little gears, underneath a thousand r.p.m.[3]
