BHS worm gears boast maximum operational reliability and a long service life, even under extreme loads. The gearboxes are attached to the mixing shafts without rigid connection to the mixing trough. Careful material pairing allows the BHS worm gearbox to compensate for the load changes that occur each time the mixer is filled.
All of our twin-shaft batch mixers are equipped with high-quality motors. They are specifically designed for the load cycles generated.
The power is transferred via V-belt drives. Positioning the V-belt drives on the outside of the drive provides good accessibility when performing maintenance work.
The adjustable torque support is used for the alignment of the gearboxes. It also allows the gearbox to be fastened to the mixing trough without pressure, avoiding unnecessary loads on the gearbox toothing. This special feature is an essential prerequisite for achieving a long gearbox life.
A low-maintenance elastic coupling is installed between the gearboxes to synchronize the two mixer shafts.
The hydrodynamic fluid coupling prevents both mechanical and electrical load peaks. Its use is recommended in particular if unstable electricity supply conditions prevail on site.
The mixer shafts are reliably sealed with axial face seals. The shaft bearings are mounted on bearing lanterns and are physically separated from the shaft seals. This significantly increases the operational reliability of the mixer shaft bearings.
