Features

Features and benefits

The BT range of bevel gearboxes is destined for all gearbox applications which depend on reliability and variability. Compact dimensions and high transmission torque at optimal performance are of central importance here. Precision of the axes and bearing seats, combined with Gleason bevel gears to take high loads, are the basis for minmized toothclearance and optimal transmission properties. The gearboxes are presently available in 9 sizes, each with a ratio range of i = 1:1 to 5:1. In addition, a further range of BM bevel gearboxes is available, which offers significantly greater torque at i = 1:1 at comparable sizes.

The housing:

single-component steel housing with maximum precision of axes and bearing seats, all integrated directly into the housing
high power density of the gearboxes through compact housing dimensions
drive-sided gearbox interface offers the option of direct connection of planetary gearbox pre-stages, as well as secure mounting of motor flanges
mounting threads on all sides of the housing allow for stable attachment of the gearbox in various installation positions

The gears:

heavy duty bevel gears, designed and manufactured according to the Gleason process, result in optimal gearing efficiency, high transmission precision and reduced stress on the bearings
friction-locked, zero backlash connection of the crown gears on the drive shaft reduces the mass of the gearing component
precise gear setting by measuring the gear box components and 100% running test of the gearboxes in assembly

The shafts and bearings:

steel alloy shafts with precise bearing seats as basis for precise and heavy duty taper roller bearings
extremely precise positioning and setting of bearings through the use of ground steel shims and splinting of the inner rings

The range of gearboxes:

at present, 9 gearbox sizes with a transmission ratio i = 1:1 to 5:1
gearbox can be supplied with solid or hollow shafts in standard and customized designs
best efficiency when high transmission performance is required. High efficiency levels of course result in a reduction of energy costs
