It sets, first gear is linked together with force-output shaft, and needle bearing is installed on the end in gear-box of force-output shaft and and gear-box
Inner wall is engaged；Inputting shaft is equipped with second gear and the second ball bearing, second gear are linked together with inputting shaft, and second
Gear is located at the end in gear-box of inputting shaft, and second gear is engaged with the first gear on force-output shaft, the second ball axis
It holds the middle part for being installed on inputting shaft and is engaged with gear chamber interior wall.
Further, a side end face of first ball bearing is butted on retaining ring, another side of the first ball bearing
Face is butted on the shaft shoulder of force-output shaft；One side end face of needle bearing is butted on another shaft shoulder of force-output shaft, needle bearing it is another
Side end face is butted on gear chamber interior wall；One side end face of the second ball bearing is butted on gear chamber interior wall, the second ball bearing
Another side end face is butted on the shaft shoulder of inputting shaft.
The beneficial effects of the utility model：This wrapping machine speed reducer breaks traditional limitation, by the first tooth on force-output shaft
Second gear on wheel and inputting shaft is connected directly, and is realized one-part form number ratio, is saved cost, while reducing deceleration body
Product installs needle bearing in the end of force-output shaft, and needle bearing can be suitably used for the restricted supporting structure of installation dimension, entirely subtract
Assembling for fast machine becomes simpler, can realize high-revolving output.
