Abstract

A hammer drill with rolling contact at the contact surfaces for transmission of axial force between a drive shaft (18) and wave race (42). By using roller bearings (38), line contact is obtained. The area of contact is thus close to zero as opposed to a relatively large area in engagement systems using toothed surfaces. Use of point or line contact reduces heat generation and reduces energy loss due to friction.
