Abstract
A rotary flexible coupling has two interleaved sets of input and output driver blocks connected to input and output flanges, respectively. First and second tires of inelastic material are spaced radially inwardly and radially outwardly from the blocks. Each block is connected to each tire by a cylindrical segment of a cylindrical layer of elastomeric material and torque is transmitted from the input blocks to the output blocks via the elastomeric layers and the tires.

In a rotary flexible coupling having first and second sets of driver blocks, the blocks of each set being spaced equally apart around the axis of rotation, the blocks of the first set being interleaved between the blocks of the second set, each of the blocks having radial end faces and having inner and outer circumferential surfaces, a first set of fastening elements to connect the first set of blocks to an input flange to receive torque therefrom, and a second set of fastening elements to connect the second set of blocks to an output flange to transmit torque thereto, the invention comprising:
- a first tire of inelastic material spaced radially inwardly from the inner circumferential surfaces of the blocks;
- a second tire of inelastic material spaced radially outwardly from the outer circumferential surfaces of the blocks;
- an inner layer of elastomeric material comprising cylindrical segments joining the inner circumferential surface of each of the blocks with the first tire;
- and
- an outer layer of elastomeric material comprising cylindrical segments joining the outer circumferential surface of each of the blocks with the second tire.
