Coaxial cylindrical gearboxes families A from the company STM These are high-tech, reliable and ready-to-use mechanical transmissions. The model range consisting of sixteen overall dimensions is represented by one-, two- and three-stage versions, such a variety covers a wide range for requests of operating parameters.
The monolithic body is made of cast aluminum (in sizes 25-50) or cast iron (in sizes 50-140) and, due to the absence of component parts, has high rigidity as opposed to high loads. The internal structure of the gearbox is designed in such a way as to optimize the circulation of lubricants, reduce noise and ensure the tightness of the structure.
There are three main configurations of gearboxes in this category
- AM - connecting flange for motor connection (IEC standard)
- On - solid shaft at the entrance
- AC - series with built-in motor
The modularity of the connecting elements at the gearbox outlet makes it easy to dock with the driven equipment without unnecessary add-ons.
