Definitions
- the screw piston of the Mohno type singlespandle excentric screw pump as the rotary part performs a complex motion outside the centreline of the pump, for this reason the torque is transmitted from the bearing supported driving shaft with cardan or other coupling realizing excentric motion.
- the radial cardan coupling with its simple construction and minimal number of component parts is up to the technical and economic requirements. Its sealing system ensures long life.
- the sealing solution is suitable for the protection against aggressive agents and solvents.
- This closed radial-cardan excentric coupling is formed in such a way, that the torque transmitting elements are radially arranged, thus surrounding each other in annular form, and requiring close installation space.
- These carrying bolts are tightly fitted in the tapered nest, whereby they ensure constant torque transmission to the carrying ring.
- the threads ensure the tight fitting of the bolt as well as its tightening in the tapered nest, in order to transmit the torque to the accurately fitting tapered surfaces.
- the carrying ring transmit the torque through the holes perpendicular to the carrying bolts to the driven excentric shaft stub 4 with bolt 6.
- the excentric shaft in this case is closed into a spherical segmental element 7 tightly fitted 8 on shaft with the shaped external packing ring 9 fixed into the accurately fitting head piece 1.
- the packing ring is protected by backing ring 10 against possible external high operating pressures. Constant pressure of the closing element 7 and packing ring 9 on the internal packing ring 8 is ensured by the spanner ring 13 acting through the backing ring 12.
- the applied method of construction ensures total protection against mechanical damages, furthermore its sealing element may be produced from teflon, which protects the machine element against all kinds of aggressive substances and solvents.
