Specific embodiment
The utility model is further described presently in connection with specific embodiment.These attached drawings are simplified schematic diagram
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figures 1 to 7, a kind of motor direct connection single-screw extruder gearbox, motor 1 and tooth including fixed setting
Roller box 2 is provided with high speed gear shaft 3 in gear-box 2, is formed between 3 input terminal of machine shaft 1A and high speed gear shaft of motor 1
Direct connection connection.Input shaft of the high speed gear shaft 3 as gear-box 2, gear and transmission gear transmission on high speed gear shaft 3 connect
It connects.High speed gear shaft 3 is mounted on inside gear-box 2 through high-speed bearing.
The direct connection connection structure specifically: axis hole is opened up in 3 input terminal of high speed gear shaft, machine shaft 1A protrudes into this in front end
In axis hole, machine shaft 1A outer wall and shaft hole inner wall offer keyway respectively, and two keyways install key block, make machine shaft 1A
Key connection is formed between 3 input terminal of high speed gear shaft.
After completing key connection, machine shaft 1A drives high speed gear shaft 3 to rotate, but can not limit well at this time
Therefore axial movement between machine shaft 1A and high speed gear shaft 3 processed, inputs to overcome the defect in high speed gear shaft 3
It holds end to form locking section, offers multiple equal part slot 3A in locking section, each equal part slot 3A is along 3 input terminal end of high speed gear shaft
Portion is circumferentially distributed, and the notch of each equal part slot 3A is axially opened up along high speed gear shaft 3；Socket outside 3 locking section of high speed gear shaft
The contraction set 5 that radial contraction can be done shrinks 5 radial contractions of set and the locking section of high speed gear shaft 3 is driven to do radial contraction deformation, and
So that 3 input terminal locking section of high speed gear shaft and internal machine shaft 1A realize radial locking.It shrinks set 5 and is doing radial contraction
When, the locking section radial contraction of high speed gear shaft 3 is driven, so that machine shaft 1A be made to drive high speed gear shaft 3 in radial direction
Realize locking.
Specifically, shrinking set 5 includes round body, contraction mouth is formed on body, is opened respectively on the body of contraction mouth two sides
If screw hole, the screw hole that clamping screw passes through contraction mouth two sides drives body institute contractile motion.It tightens clamping screw and shrinks 5 contraction of set
High gear axis hole, clamping motor shaft 1A centering.
