For continuous transmission of motion, the contact ratio i.e. n must always be _______
View Answer Explanation
Two involute gears have path of contact 40 mm and the pressure angle is 50°. Find the arc of contact.
Two gears in a mesh have the arc of contact = 27 mm. The pressure angle is 15°. Find the path of contact.
Two involute gears in a mesh have a circular pitch of 25 mm. The arc of contact is 55 mm. Find the number of pairs of teeth in contact.
Two involute gear have a module of 5 mm, the arc of contact is 25 mm. Find the contact ratio of these two gears.
The path of contact of two gears in a mesh is 50 mm and the pressure angle is 45°. The module is 8 mm. Find the contact ratio of these two gears.
The path of approach = 13.92 mm and path of recess = 11.56 mm. The pressure angle is 22.5°. The module is 4 mm. Find the contact ratio of these two gears.
Two involute gears in a mesh have a module of 10 mm and the pressure angle is 35°. The larger gear has 45 teeth whereas the pinion has 15 teeth. The addendum is equal to one module. Find the arc of contact.
The pressure angle of two gears in a mesh is φ = 22.5°. The number of teeth on the pinion is 25 and the gear ratio is 2. The module is 7 mm and addendum = 1 module. Find the angle of action of these two gears.
The pressure angle of two gears in a mesh is φ = 25°. The number of teeth on the pinion is 45 and the gear ratio is 2. The module is 6 mm and addendum = 1.1 module. Find the contact ratio of these two gears.
If the maximum addendum radius of the wheel is given as 260 mm and the actual value of the addendum radius is found out to be 255 mm, the interference will occur. True or false?
