CONFIGURATION AND DIRECTION OF ROTATION

Tab.1

AVAILABLE VERSIONS
⟪A⟫	⟪B⟫

2 outputs, same rotation direction	3 outputs, same rotation direction

⟪C⟫	⟪D⟫

3 outputs, 1 with opposite rotation directions	3 outputs, 2 with through hollow shafts, same rotation direction
The direction of rotation depends from the configuration and from the mounting positioning, see Tab. 4.

REFERENCE RULES
Shaft 1 is always shown on the side opposite the M_1 fixing bores and serves as the reference for determining:
● the configuration
● the direction of rotation
● the gear ratio
By convention, Shaft 1is shown rotating clockwise. The others shaft are defined following the clockwise direction.

AVAILABLE TRANSMISSION RATIOS

Tab.3

The ratio is determined by the shaft1always shown on the opposite side of the fixing bores M_1.
Ratio 1/1	Ratio 1/2	Ratio 2/1

Example	Example	Example
Shaft 1 = 10 rpm	Shaft 1 = 10 rpm	Shaft 1 = 5 rpm
Shafts 2-3 = 10 rpm	Shafts 2-3 = 5 rpm	Shafts 2-3 = 10 rpm
		not available in version D

M_ FIXING POSITIONS

Tab.4

Shaft 1 remains the reference and is conventionally shown rotating clockwise; the housing is rotated by 90° from the previous position.
