The direction of rotation depends from the configuration and from the positioning..

REPRESENTATION OF BEVEL GEARS
Straight bevel gears		Spiral bevel gears ‹SP›

Suitable for moderate loads and speeds		Suitable for loads + 30% and high speeds

REPRESENTATION OF TRANSMISSISSION RATIOS

The ratio depends on shaft ‹1› shown opposite the fixing bores M_
example: ratio 1:2	example: ratio *2:1
shaft 1 = 10 rpm	shaft 1 = 5 rpm
shaft 2 = 5 rpm	shaft 2/3 = 10 rpm
	* not available in version «D»

RAFFREPRESENTATION OF DESIGN CONFIGURATION

The design depends on shaft 1opposite the fixing bores M_; others shafts follow clockwise.

REPRESENTATION OF LOADS
«B»	«D»

Fr = radial load 750 N The radial load is applied perpendicular to the axis of the shaft. Fa = axial load 75 N The axial load (push or pull) acts along the direction of the shaft. T = torque 45 Nm
Note: a radial load (ex. belt tension) can only be applied to the long shaft of the «B» and «D» versions; otherwise, a support must be provided.

COUPLING BUSHES 2 piece bushing to couple gearboxes and shafts.

Available bores Ø: 6 - 8 -10 -14.
