Gearboxes Provide Precision to the Auto Industry

EXSYS Tools gear housings offer reduced stress on the bearings.

EPPINGER’s BT (bevel torque) and BM (bevel maximum torque) compact spiral bevel gear boxes are now being offered. They deliver high torque and maximum efficiency for gear applications that require extreme reliability and variability at speeds over 1,000 RPM, as is the case for vehicle differentials.


Each of these bevel gearbox types offers minimized tooth clearance and optimal transmission properties via precision axes and bearing seats combined with GLEASON bevel gears that can withstand high loads.


The single-component steel housings for these bevel gearboxes feature mounting threads on all sides to ensure stable attachment in a variety of installation positions. The heavy-duty bevel gears inside these housings offer high-transmission precision and reduced stress on the bearings. A friction-locked, zero backlash connection of the crown gears on the drive shaft reduces the mass of the gearing component.


Both BT and BM gearboxes come in solid or hollow shafts in standard and custom designs. BT-type models are available in seven sizes with a transmission ratio of i = 1:1 to 5:1, while BM-type models are available in five sizes with a ratio of i = 1:1.
