Gearboxes - General information
- Universally applied, suitable for all industrial applications where it is necessary to transmit rotary motions between two shafts at right angles.
- Compact and modular design, highly adaptable, easy installation.
- Manual or motorized motion, flanges available for coupling to machines, motors, display units.
- Wide range of input and output shafts with keyways.
- Special versions available upon request.
● Gearboxes models ‹66› for intermittent use
- 5 sizes identified as 66/22 - 66/4 - 66/5 - 66/6 - 66/8.
- 5 configurations identified as «A»- «B» - «C» - «D» - «E», with protruding output shafts identified as ‹M› (male), blind and through females identified as ‹F› (female): standard shaft diameters Ø 6 - 8 - 10 - 12 - 14 - 20 mm.
- Models with straight bevel gears.
- Models with spiral bevel gears for higher precision, silent operation, and 30% increased output torque.
● Gearboxes models ‹66_UC› for continuous use
- 3 sizes identified as 66/4UC - 66/5UC - 66/6UC.
- 4 configurations identified as «A»- «B» - «C» - «D», with protruding output shafts identified as ‹M› (male), blind and through females identified as ‹F› (female): standard shaft diameters Ø 8 - 10 - 12 - 14 - 20 mm.
● Flanged gearboxes models ‹RINV-OP›
- Flanges for coupling on the machine side and for motors.
- Flanges and shaft extension for visualized adjustment for coupling with mechanical and electronic position indicators.
- 3 sizes identified as RINV-OP62 - RINV-OP64 - RINV-OP65.
● Application fields: packaging, food, pharmaceutical, civil engineering machines, traditional and special machines in metal-, wood-, glass- working/processing, in lifting, winding and unwinding machines, milling machines, conveyors, linear guides, ... .
APPLICATION EXAMPLES |
GENERAL DATA | Tab. 6 |
Casing material: | |
grey anodized aluminum for 66/4 - /5 - /6 - /8; black anodized aluminum for 66/22,RINV-OP; AISI 303stainless steel (on request) | |
Shaft material: | |
AISI 303 stainless steel | |
Gear material: | |
steel with wear-resistant surface hardening treatment | |
Gear play tolerances: | |
from 0.1 ° to 0.75 ° (smaller tollerances on request ①); minimum backlash and axial play |
|
Bearings: | |
ball-bearing of the best brands suitably sized to ensure long life | |
Lubrication ②: | |
long life Klüber AG 11-462 grease; on request available Klüber H1 grease for food/pharmaceutical industry, and for high temperatures | |
Transmission ratios ③: | |
1:1 - 1:2 reduction, 2:1 multiplication; the total efficiency of the transmission is 90% |
|
Working temperature: | |
-10° + 50° |
|
Available torques: |
|
from 2 Nm to 80 Nm |
|
① Excessive play reduction, could cause blockage of the transmission; the play tends to grow with the gear wear |

CONFIGURATIONS AND DIRECTION OF ROTATION | Tab. 1 |
⟪A⟫ | ⟪B⟫ | ⟪C⟫ |
⟪D⟫ | ⟪E⟫ |
The direction of rotation depends from the configuration and from the positioning; see "Versions with dimension drawings" for each model. |
REPRESENTATION OF BEVEL GEARS | Tab. 2 | |
Fig. 1 | Fig. 2 | |
Straight bevel gears | Spiral bevel gears | |
The spiral gearboxes allow high precision, silent operation, and 30% increased output torque. |
REPRESENTATION OF REDUCTION & MULTIPLYING RATIO |

Fig. 3 | Fig. 4. | |||
Example with ratio 1:1 | Example with ratio 1:2 | Example with ratio 2:1* |
SHAFT ‹1› = 10 RPM | SHAFT ‹1› = 10 RPM | SHAFT ‹1› = 5 RPM |
SHAFT ‹2› = 10 RPM | SHAFT ‹2› = 5 RPM | SHAFT ‹2› = 10 RPM |
* ratio 2:1: on request; not available in version «D» | ||
The ratio (Fig. 3-4) and configuration is determined by the shaft ‹1› always shown on the opposite side of the fixing bores M_, the others shaft are defined following the clockwise direction. |
