Worm gear slewing drive and worm structure is often used to transfer motion and power between two staggered shafts.Worm gear and worm in the middle plane is equivalent to gear and rack, worm and screw shape is similar.
SVH7 dual axis slewing drive gearmotor is available for 6-10pcs panels solar tracker application
For 6-10pcs solar panels tracking design
For 500-800kg load weight application
Mechanism Characteristics
1.Double output structure
2.SVH7 is made by framework oil sealing structure,so the waterproof and dustproof is much better than normal oil sealing production.
3.Special heat treatment,corrosion resistance
4.Built-in eccentric mechanism, ensure the accuracy requirements of the slewing drive
5.SVH7 have 8 bolts on worm shaft side,the original model just have 4 bolts.So,the axial load of SVH7 is more steady than the other model.
