Penetrate on the stator in boring a hole into pedestal and rotor.
Offering osculum below drive end bearing bracket, connect with the airtight water channel of support, the effect in this axial hole is: in the north
In winter, when needing to discharge the water in airtight for support water channel, by this hole, water can be discharged.
Beneficial effects of the present invention: the present invention eliminates the welding procedure closing water cooling base water channel, utilizes in front end
Lid, rear end cap and the sealing ring set by support, at the end cap formation sealing function that drive end bearing bracket contacts with support with rear end cap, from
And instead of the welding procedure that tradition water cooling base water channel seals, solve and easily produce asking of fatigue crack in plumb joint position
Topic, reaches simple in construction, and closed performance is good, the effect of reliable operation, fixed, and the scope being suitable for is wide, improves and manufactures and raw
The efficiency produced.
