The STG gearbox from Dunkermotoren, featuring Spirotec gearing, is an angular gearbox developed for the long service life of BG motors. Further features of the Spirotec gearbox are a high transmittable torque, high robustness and low-noise operation.

Spirotec gearing is a special type of Spiroid gearing in which the gearing parts are designed as a pairing of a helical pinion and a spiral-toothed ring gear. The cylindrical pinion allows free axial positioning, which is the basis for the simplified assembly of the gear parts. In addition, the Spirotec gearing is said to achieve a higher degree of efficiency than other worm gear units.

With a maximum service life of 22,000 h, the unit — combined with the BG65 brushless motor — is designed to be suitable for most high-tech machine drive applications in today’s market.
