Abstract
A coupling arrangement for coupling a driving means, typically a motor, to a hollow rotor and stationary shaft combination, which arrangement includes a rotor having a working formation and hollow cylindrical member extending axially from a shoulder formation (not shown) at one end of the working formation, the member provided with a thread (not shown) on its outside, which, in use is threaded into a complementary cylindrical hollow part of the motor and wherein the threads have a tightening direction which is the same as the direction of the motor, such that in use, when the motor drives the member, the member is tightened onto the rotor.
Claims8
A coupling arrangement for coupling a driving means to a hollow rotor and stationary shaft combination, which arrangement comprises:—
- a rotor having a working formation and hollow cylindrical member extending axially from a shoulder formation at one end of the working formation, the member provided with a thread on its outside, which, in use is threaded into a complementary cylindrical hollow part of the driving means and wherein the threads have a tightening direction which is the same as the direction of the driving means, such that in use, when the driving means drives the member, the member is tightened onto the rotor;
- a lateral force transferral means for laterally transferring force from an end of the cylindrical hollow part of the driving means to the shoulder formation of the rotor, which lateral force transferring means comprises a combination of one or more of abutting sleeves and radial bearings;
- and
- at least two roller bearings mounted inside the hollow cylindrical member between the member and a stationary shaft, which bearings are positioned opposite the cylindrical hollow part of the driving means and its abutting sleeve and bearing combination on the outside of the cylindrical member.
