BZ CROWNED GEAR COUPLINGS SIZES FROM 1,300-348,000 Nm MODEL FEATURES BZ1 with keyway mounting high power

2 BZ CROWNED GEAR COUPLINGS SIZES FROM 1, ,000 Nm MODEL FEATURES BZ1 with keyway mounting high power density very low backlash economically priced low maintenance due to special crowned tooth design Pages

3 GENERAL INFORMATION CROWNED GEAR COUPLINGS FUNCTION OF THE GEAR COUPLING The precise integration of the coupling hub and intermediate flange allow for low backlash and highly rigid torque transmission, while compensating for lateral, axial, and angular shaft misalignment. The crowned geometry of the gearing allows for a long life, even without the presence of misalignment. Axial misalignment Angular and lateral misalignment precision crowned teeth straight teeth in flange coupling hub moves axially within the flange coupling hub tilts within the flange CROWNED GEAR COUPLINGS BZ RW-AMERICA.COM 79
