Friction shaft coupling and lower structure of tearing formula runner open and being applied to vertical mixed flow machine

The utility model discloses a friction shaft coupling and lower structure of tearing formula runner open and being applied to vertical mixed flow machine, it includes upper segment tail water taper pipe, hypomere tail water taper pipe, rolls turner utensil, runner, main shaft flange, upper segment tail water taper pipe with for can dismantle the connection between the hypomere tail water taper pipe, the periphery of upper segment tail water taper pipe, hypomere tail water taper pipe all is the cavity, set up on the hypomere tail water taper pipe and roll the turner utensil, roll the turner utensil and be located the instrument track, runner and main shaft flange be connected spraying rubbing agent on runner or the main shaft flange of face department. Thereby reduced the time of maintenance, maintenance, increased the economic benefits of power station operation, must consider during implementation that tail water taper pipe, leak-stopping trade, and the necessary safe and reliable of measure that carefully transfers when dismantling of bottom ring.
