Question

How is power transmitted from drill spindle to drill shank?

Answer 1

The answer is friction drive.

Power is transmitted from drill spindle to drill shank using a friction drive. A friction drive uses two wheels to transmit the power in place of the standard chain and sprockets. However, its efficiency is on the lower side. This mechanism is often found in scooters.

Answer 2

Power is transmitted between the penetrating shaft and drill shank through FRICTION drive (Taper shank push fitted into spindle taper).

A friction drive or friction motor is a sort of transmission that, rather than a chain and sprockets, utilizes 2 wheels in the transmission to exchange energy to the driving wheels.

Since the output wheel (leather secured wheel) has a width, the region of contact is spread crosswise over different radii on the primary disc.
