In a gear transmission, pairs of helical gears are rotatably mounted on a drive shaft for axial movement on the drive shaft. The pairs of helical gears mounted on the drive shaft engage corresponding pairs of helical gears rotatably mounted on a driven shaft for axial movement on the driven shaft. Retainer members are located adjacent each end of at least one of the shafts to restrict axial movement by helical gears caused by axial separation between pairs of helical gears resulting from commencement of rotation of the drive shaft. |
