Worm drive for single axis tracking system in trough solar power

Parabolic trough use a curved,mirrored trough which reflects the direct solar radiation onto a glass tube containing a fluid running the length of the trough,positioned at the focal point of the reflector. It requires higher output torque and holding torque for slew drive. By means of advanced heat treatment technology, SBI vertical worm drive and horizontal worm drive with DC motor can meet the requirements of trough solar power tracker. Therefore, it is very suitable for this applications for saving more installation space and charges.

Zero backlash slew drive gives low torque and low speed because of zero or small transmission clearance. Compared with the slew drive with same specifications,output torque of zero backlash slew drive reduced by 45%。 Our clients should pay attention to the above item.


1.Arc tooth surface and hourglass worm reach stronger anti-fatigue and anti-glued

2.Pass the ISO 9001

3.The products include vertical,horizontal,precision and zero backlash worm drive,total 4 types.


The worm drives are most commonly used in solar trackers, specially CPV, solar trough and heliostats to focus on a single point.
