<p>A gear coupling between a power drive shaft (1) and a power driven shaft (2) comprises a drive member (3) and driven member (4) which extend into, a hollow intermediate member (5), the drive member (3) and preferably also the driven member (4) engage the intermediate member 5 by means of helical gear teeth (3B, 5A, 4B, 5B) and a resilient member (6) such as a bank of disc springs is present between the drive member (3) and the intermediate member (5), to counterpart axial separating forces resulting from torsional shock loads. The gear coupling may be used for example in drilling equipment used in mines.</p> |
