Humpage Speed Reduction Gear with diagram

Humpage Speed Reduction Gear:

The Humpage Speed Reduction Gear was originally designed as substitute for back gearing of a lathe. But its use in now considerably extended to all kinds of workshop machines and also in electrical machinery. In humpage’s speed reduction gear as shown in fig:

The driving shaft X and the driven shaft Y are co-axial. The driving shaft-carries a bevel gear A and driven shaft carries a bevel gear E. The bevel gear B meshes with gear A also known as pinion and a fixed gear C. The gear E meshes with gear D which is compound with gear B. This compound gear B-D is mounted on the arm or spindle F which is rigidly connected with a hollow sleeve G. The sleeve revolves freely loose on the axes of the driving and driven shafts.
