Angular conical-cylindrical gearboxes families O from the company STM These are high-tech, reliable and ready-to-use mechanical transmissions. The model range consisting of fourteen overall dimensions is represented by three-stage versions, a wide range of available operating parameters.
The monolithic body is made of cast aluminum (in sizes 63-71) or cast iron (in sizes 80-190) and, due to the absence of components, 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
- OM - connecting flange for motor connection (IEC standard)
- OR - solid shaft at the entrance
- OC - 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. The following possible output shaft options are offered: solid double, slotted, double slotted and double flanged, hollow with a keyway, with a quick locking device or with a shrink disc. On request, a jet rod can be included in the package.
