Which of the following statements are correct for mating gears with involute profiles? (i) The pressure angle, from the start of the engagement to the end of the engagement, remains constant. (ii) The pressure angle is maximum at the beginning of the engagement, reduces to zero at pitch point, starts decreasing and again becomes maximum at the end of the engagement. (iii) The face and flank of the teeth are generated by a single curve and the normal to this curve at any point is tangent to the base circle of the gear. (iv) The centre distance for a pair of mating gears can be varied within limits without altering the velocity ratio. Select the correct answer using the code given below.
Consider the following statements in case of reverted gear train: 1. The direction of rotation of the first and the last gear is the same. 2. the direction of rotation of the first and the last gear is opposite. 3. The first and the last gears are on the same shaft. 4. The first and the last gears are on separate but co-axial shafts. Which of these statements is/are correct?
Consider the following modifications regarding avoiding the interference between gears: 1. The centre distance between meshing gears be increased 2. Addendum of the gear be modified 3. Teeth should be undercut slightly at the root 4. Pressure angle should be increased 5. Circular pitch be increased Which of these are effective in avoiding interference?
which type of gears has point contact between two mating gears?
The other gears are the ............... gears which are those most used in normal driving.
Miter gears are the bevel gears mounted on shaft which are intersecting at angle greater than 90.
The gears are termed as medium velocity gears, if their peripheral velocity is
Two advantages of using helical gears rather than spur gears in a transmission system are
Involute gears have greater contact area as compared to cycloidal gears.
If centre distance between the two gears on same shaft is unequal to the centre distance on the other two gears on the second shaft, then this gear train is called reverted gear train.
