Summary of the invention
The invention provides a kind of relieving attachment and method for dismounting thereof of motor shaft end fan hot jacket wheel hub, solved prior art easy technical problem that scratches and destroy motor shaft end and fan hub when the fan hub of dismounting motor shaft end.
The present invention solves above technical problem by the following technical programs:
A kind of relieving attachment of motor shaft end fan hot jacket wheel hub, comprise machine shaft, axle head hot jacket at machine shaft has wheel hub, in the axle head of machine shaft, be provided with oil filler point, port at oil filler point is provided with internal thread, on the axle head lateral surface of machine shaft, is provided with annular oil groove, and annular oil groove passes through radially Oil Guide path and is communicated with oil filler point, front end at the pump nozzle of oil pump is provided with external screw thread, and the internal thread that the pump nozzle of oil pump and the port of oil filler point arrange is screwed together.
On the axle head lateral surface of machine shaft, be provided with abreast multiple annular oil grooves, each annular oil groove by one radially Oil Guide path be communicated with oil filler point.
A method for dismounting for motor shaft end fan hot jacket wheel hub, comprises the following steps:
The first step, in the axle head of machine shaft, oil filler point is set, port at oil filler point arranges internal thread, on the axle head lateral surface of machine shaft, annular oil groove is set, annular oil groove passes through radially Oil Guide path and is communicated with oil filler point, front end at the pump nozzle of oil pump arranges external screw thread, and the internal thread that the port of the pump nozzle of oil pump and oil filler point is arranged is screwed together;
Second step, startup oil pump, be injected into hydraulic oil in oil filler point, and the hydraulic oil of injection radially Oil Guide path enters after annular oil groove, and motor shaft end fan hot jacket wheel hub is strutted;
The 3rd step, unload motor shaft end fan hot jacket wheel hub.
The present invention has scene and draws materials easily, and feature simple to operate protects motor shaft not to be scratched well when the fan hub of dismounting motor shaft end.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of relieving attachment of motor shaft end fan hot jacket wheel hub, comprise machine shaft 1, axle head hot jacket at machine shaft 1 has wheel hub 5, in the axle head of machine shaft 1, be provided with oil filler point 7, in the port of oil filler point 7, be provided with internal thread 2, on the axle head lateral surface of machine shaft 1, be provided with annular oil groove 4, annular oil groove 4 is communicated with oil filler point 7 by Oil Guide path 3 radially, front end at the pump nozzle 8 of oil pump 6 is provided with external screw thread 8, and the pump nozzle 8 of oil pump 6 is screwed together with the internal thread 2 that the port of oil filler point 7 arranges.
On the axle head lateral surface of machine shaft 1, be provided with abreast multiple annular oil grooves, each annular oil groove by one radially Oil Guide path be communicated with oil filler point 7.
A method for dismounting for motor shaft end fan hot jacket wheel hub, comprises the following steps:
The first step, oil filler point 7 is set in the axle head of machine shaft 1, in the port of oil filler point 7, internal thread 2 is set, on the axle head lateral surface of machine shaft 1, annular oil groove 4 is set, annular oil groove 4 is communicated with oil filler point 7 by Oil Guide path 3 radially, front end at the pump nozzle 8 of oil pump 6 arranges external screw thread 8, and the pump nozzle of oil pump 68 and the internal thread 2 that the port of oil filler point 7 arranges are screwed together;
