CONFIGURATION AND DIRECTION OF ROTATIO
⟪A⟫	⟪B⟫	⟪C⟫

⟪D⟫	⟪E⟫

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 150 N The radial load is applied perpendicular to the axis of the shaft. Fa = axial load 15 N The axial load (push or pull) acts along the direction of the shaft. T = torque 4 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.

Configuration examples
Gearbox with 2 shafts	Gearbox with 3 shafts

Male shaft with flange MØ14x68 FL-OP3/EP3, compatible with any configuration and output shaft of the gearbox, connects the position indicator, whether mechanical or electronic, to the gearbox. This combination enables precise and monitored position adjustment, increasing stability and accuracy of readings. Made of black anodized aluminum, it is coordinated with the gearbox case, also in black.
