B&R: Helical gearboxes
B&R’s two new helical gearboxes, the 8GP70 series with a shaft output and the 8GF70 series with a drive flange, provide smooth operation for absolute precision, excellent synchronization characteristics, and a very low noise level at high speeds.
As with all its premium gearboxes, minimal backlash is a defining characteristic – with an option available for reducing it even further (<1 arcminute). The ability of this premium series of gearboxes to handle high axial and radial forces, their high power density, and their IP65 rating mean that they can be used in an extremely wide range of applications.
The helical gearboxes are suitable for applications that place especially high demands on smooth operation, synchronicity, and low excitation frequencies. Since there is less heat build-up, high-speed machines can run even faster.
By offering these new gearboxes with either a standard shaft or flange output, B&R not only provides the right gearbox for the application, but provides a successful Scalability+ concept. Compatible designs and connector dimensions allow machinery to be easily adapted to changing requirements without having to make changes to the basic machine design. Both of these new gearboxes are available in 5 different sizes with gear ratios ranging from i=3 to i=100.
