The diameter of one shaft part is more than the diameter of the second shaft part, and the diameter of third shaft part is also greater than the diameter of the second shaft part, but third shaft part
Diameter be less than the first shaft part.Keyway on first shaft part is processed by milling machine and obtained, and the first set flat key exists in keyway
Intimate general flat key in shape achievees the purpose that spiral crushes, is arranged on the acting surface of the flat key to increase crushing effect
The face of main pulverization, that is to say the both sides of flat key from when wedge-shaped notch, acting surface here mean comminuting matter.Wedge
Shape notch ends at the other end of flat key since one end of flat key.To further enhance crushing effect, in two sides of flat key
Wedge-shaped notch is respectively provided on face, two wedge-shaped notches are parallel.
The utility model has the beneficial effects that：
1, opened up keyway on the periphery of the first shaft part, corresponding flat key be configured in keyway, the flat key be up to
The effect crushed to spiral, has opened up wedge-shaped notch on the double side acting face of flat key, has cut off the flat key left by wedge-shaped notch
Part forms a ramp-like body, and an approximate spiral rib plays same crushing effect；Importantly, keyway, flat
Key and wedge-shaped notch can be easy to processing on milling machine and be made, and for the casting of conventional master spindle rib, not only increase
Machining accuracy, while also reducing production cost.
2, multiple fan leafs are provided on the shaft part between two bearings of driving section, these flabellums are weldingly fixed on axis
Duan Shang, with the rotation of main shaft, which can follow rotation, act as the role of cooling, largely facilitate the drop of bearing
Temperature；It in addition, the fan leaf is connected between two bearings, can be used for the axially position of bearing, act as the role of " shaft shoulder ", nothing
" shaft shoulder " need to be specially designed, while cooling down conducive to bearing, also simplifies manufacturing process.
