Specific embodiment
To be understood technical solution of the present invention is further, the present invention is further retouched now in conjunction with attached Fig. 1 and 2
It states:
In conjunction with attached drawing 1, a kind of spiral runner for hydroelectric generator, including axle journal 1, axle sleeve 2, bearing shell 6, bearing block 7,
Channel steel 9, support foot 10, outer cylinder 11, the second bolt 12, inner cylinder 15, quadrate support frame 16 and helical blade 17；The inner cylinder
15 are welded with helical blade 17 along axial outer ring；Outer cylinder 11, and helical blade 17 and outer circle are set with outside the inner cylinder 15
It is not contacted between 11 inner walls of cylinder；The inner cylinder 15 is welded with axle journal 1 along the outer wall of axis both ends；The axle journal 1 passes through axis
Watts 6 are mounted on bearing block 7；Channel steel 9 is welded on 7 circumference of bearing block；The channel steel 9 is three, and channel steel 9 is respectively welded
It is on left and right, upper three directions of 7 circumference of bearing block and symmetrical about vertical axes face；Described 9 one end of channel steel passes through the second bolt
12 are fixed on support foot 10；The support foot 10 is welded on quadrate support frame 16；16 vertical welding of quadrate support frame is outside
On cylinder 11.
In conjunction with attached Fig. 1 and 2, axle journal 1 and axle sleeve 2 are provided with keyway, 2 sets of axle sleeve on axle journal 1, and it is circumferentially fixed with key 3；Axis
Set 2 uses 2Cr13 material, and modifier treatment；Block 4 pushes down the tail end of axle sleeve 2, the first bolt 5 connection fastening block 4 and axle journal
1；Bearing shell 6 is embedded in bearing block 7, and fixed with junction of the edges of two sheets of paper screw 8；Bearing shell 6 uses bronze material；Channel steel 9 is welded on bearing block 7
On, support foot 10 is welded in quadrate support frame 16, and the second bolt 12 connects channel steel 9 and support foot 10；Channel steel 9 and quadrate support frame 16 bore
