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 (the seats are never perfectly in phase, higher accuracy on request).

● Gearboxes models “66”
- 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 (Tab. 1).
- Standard models with straight bevel gears (Fig. 1); available with spiral bevel gears (Fig. 2) in the current configurations. The〚SP〛spiral gearboxes allow high precision, silent operation, and 30% increased output torque.
- The ratio (Tab. 3) and configuration is determined by the shaft ‹1› always shown on the opposite side of the fixing bores, the others shaft are defined following the clockwise direction .
(☞ )

● Flanged gearboxes models “RINV-OP”
Combined with a position indicator allows a numeric adjustment with several visualizations and connection possibilities.
- 3 sizes identified as RINV-OP62 - RINV-OP64 - RINV-OP65; configurations with two outputs.

▪︎ 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

Casing material:	Tab. 6
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*); minimum backlash and axial play
Bearings:
ball-bearing of the best brands suitably sized to ensure long life
Lubrication**:
long life Klüber AG 11-462 grease; on request available Klüber H1 grease for food/pharmaceutical industry, and for high temperatures
Transmission ratios:
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
* Excessive play reduction, could cause blockage of the transmission; the play tends to grow with the gear wear ** no maintenance; periodically it is necessary to verify the absence of leaks from the unit

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 'SP'

Spiral gearbox with 2 outputs	Spiral gearbox with 3 outputs

The spiral (Fig. 2) gearboxes allow high precision, silent operation, and 30% increased output torque.

REPRESENTATION OF REDUCTION & MULTIPLYING RATIO

Tab. 3

Fig. 3

Fig. 4

Example

ratio 1:2

SHAFT ‹1› = 10 RPM

SHAFT ‹2› = 5 RPM

----------------------------------

ratio 2:1*

SHAFT ‹1› = 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 (✳︎), the others shaft are defined following the clockwise direction .

REPRESENTATION OF LOADS

Tab. 4

Fig. 5

Fr = radial load, is the load acting in perpendicular direction to the shaft/axis

Fa = axial load, is the load acting of the shaft/axis

T = output torque

The loads acting on the shafts can be of two types, referred to the axis of the shaft (Fig. 5):

Fr - radial load

Fa - axial load, when ordering specify whether the axial load is 'pull' or 'push' type.

«The loads are generated by the items connected to the gearbox and can be created for example by the pull of belt drives, accelerations and decelerations, structural misalignments, vibrations, shocks, etc.»

GEARBOX LIFETIME CALCULATION

Tab. 5

Calculation applied to all models

THEORETIC EXPECTED LIFE^✽ = 10.000H X Fu

RECOMMENDED TORQUE (Nm)

Fu = -----------------------------

APPLIED TORQUE (Nm)

✽ The lifetime of 10.000h considers the following conditions:

• Applied torque = advised torque (see tables)

• Maximum of 8 working hours per day

• Working temperature 20°

• No shocks

• Output torque actually applied

• Max torque applied (see tables/models)

⦿ For correct sizing is necessary to know: transmitted power (Pn), output torque (T) and input rotation speed (rpm).

⦿ To identify the most suitable gearbox for your requirements, refer to the values in the table. If the real loads and efficiency are very close to the table values, contact the technical department.

⦿ All tables show linear measurements expressed in <mm>, unless otherwise specified. All the reduction ratios are expressed as a <fraction> unless otherwise specified. All forces, efficiency and the loads are expressed in <N or Nm> (10 N ≅ 1 kg or 10Nm ≅ 1Kgm ) unless otherwise specified.

GREASE FITTING

Tab. 7

Fig. 6

Fig. 7

Gearboxes with 2 outputs

Gearboxes with 3 outputs

Grease fitting: recommended when the work conditions are not within the parameters listed in Tab. 5 (page 6), to increase the lifetime of the unit, and if its position does not allow easy substitution.

It is necessary, based on the duty cycle, to restore the correct amount of lubricant at variable time intervals (contact our Tech Dept for further information).

The standard position of the grease fitting is shown in Fig. 6 and Fig. 7; it is possible to request a different position by contacting our Tech Dept.
