Detailed Description
The utility model discloses a realize through following technical scheme.
Fig. 1 is a block diagram of a turbine cooler housing and a slinger, wherein the slinger 6 penetrates and falls into the turbine cooler housing 5, the inner ring of the housing is made of a bus alloy material, the material is soft, and the radial clearance between the slinger 6 and the turbine cooler housing 5 is small.
A propulsion device of a hydro-turbo cooler oil thrower comprises a push rod 3, a coaxial centering wheel 4 and a connecting seat 1; the push rod 3 is of a two-stage step shaft structure which is coaxial with a small upper part and a big lower part, and a section of shaft at the upper part can be in clearance fit with an oil thrower 6 and an inner hole of the coaxial centering wheel 4; the two-section shaft at the lower part is in clearance fit with the inner hole of the connecting seat 1 and can slide in the inner hole of the connecting seat 1. The outer circumference of the two-section shaft is provided with a spiral groove, and the side wall of the connecting seat 1 is radially provided with a pressure relief hole communicated to the inner hole of the connecting seat 1. The length of the two-section shaft is not less than the length of the inner hole of the connecting seat 1.
The upper part of the coaxial centering wheel 4 is provided with a handle, the handle and the lower part of the coaxial centering wheel can be connected with a cylinder in clearance fit with an inner hole of the shell 5 through a transition section, and the handle, the transition section and the cylinder are coaxial. A cylinder at the lower part of the coaxial centering wheel 4. The surface of the handle is provided with an anti-skid structure.
When the installation turbine cooler, place turbine cooler casing 5 on connecting seat 1, prop disc 6 by the two-stage shaft that is located the 3 lower extremes of push rod, the cylinder with the 4 lower parts of coaxial centering wheel and 5 hole clearance fit of turbine cooler casing, one section axle of push rod 3 passes behind 6 holes of disc and 4 hole clearance fit of coaxial centering wheel, adjust the radial position of turbine cooler casing 5 on connecting seat 1, fasten turbine cooler casing 5 and connecting seat 1 with screw 2, the axial bulldozes push rod 3, install disc 6 in turbine cooler casing 5.
