Whole pin 7, positive backlash eliminate component and are harmonious fixed with reversed backlash elimination component and are fixed by adjusting pin, it is only necessary to rotate and adjust
Whole pin adjusts the relative angle that positive backlash eliminates component and reversed backlash elimination component, so that it may realize the fixed tooth of centre-to-centre spacing
The backlash of wheel transmission eliminates.
As shown in fig. 6,7 structure of adjusting pin is an eccentric shaft, in gear 3 and gear 4, gear is adjusted
3 compared with gear 4 angle.
The forward direction tooth space eliminating mechanism F is set there are one driving gear 6, a driven gear 4, two gears respectively with
Driving shaft 2 and driven shaft 1 are fixed, and are engaged in the positive transmission of gear, can eliminate backlash in the positive transmission of gear.
The reversed tooth space eliminating mechanism E is set there are one driving gear 5, is fixed with driving shaft 2, a driven gear 3,
It can rotate low-angle compared with driven shaft 1, then fixed with driven shaft 1, gear is made to be engaged in reverse drive, it can be in gear
Backlash is eliminated during reverse drive.
In summary：Gear 4 and gear 6 are engaged in the positive transmission of gear, adjust adjusting pin, gear 3 and gear 5 is made to exist
It is engaged during gear reverse drive, realizes the purpose of backlash between elimination gear drive engaging tooth.
Be driven in use, setting in Fig. 1 arrow direction as gear is positive, gear 5 and gear 6 are driving gear, the number of teeth and
Modulus is identical, is fixed together with driving shaft 2, and gear 3 and gear 4 are driven gear, and the number of teeth is identical with modulus, gear 4 with from
Moving axis 2 is fixed together, and is engaged in the positive transmission of gear with gear 6, so as to eliminate the positive transmission backlash of gear.
Gear 5 and gear 6 are coaxial, and gear 3 and gear 4 are coaxial.Equipped with adjusting pin 7 in the pin hole of gear 3, adjusting pin is another
It holds as an eccentric shaft, eccentric end is mounted in the slot hole of gear 4, and adjusting pin 7 is rotated with allen wrench, makes gear 3 opposite
The rotation of low-angle is done in gear 4, gear 3 and gear 5 is made to be engaged in gear reverse drive, then will be adjusted with hex nut
