4 - Question
Bevel gears used for connecting intersecting shafts at 900 and having speed ratio 1 : 1 is known as
a) bevel gears
b) beveloid gears
c) mitre gears
d) none of the mentioned
View Answer
Answer: c
Explanation: Bevel gears used for connecting intersecting shafts at 900 and having speed ratio 1 : 1 is known as mitre gears.
Bevel gears with basic pressure angle of 200 with long and short addendums for ratios other than 1:1 to avoid undercut pinions and to increase strength are gleason bevel gears.
