After selecting the drive units, please check the following:

a) Thermal power

Make sure that the thermal capacity of the gearbox is equal to or greater than the the mechanical power required by the application, as per equation (24).If this is not the case provide a supplementary cooling system or select a larger gearbox.When the duty cycle is formed by short operating periods and rest time is long enough for the unit to cool down, the thermal capacity is hardly signifi cant and it may be omitted from calculation.For ambient temperatures other than 20°C, intermittent duty and drive speed n1 other than the refer-ence speed listed in the rating charts, Pt is to be adjusted through thermal factor ft and/or speed factor fv as listed in table (A7).Finally, make sure that the following condition is always satisfi ed:

Should the gear unit in the conventional confi guration fall short of thermal capacity and not verify the condition (24) above, it is recommended to apply the following executions:

1) fan cooled input shaft - ordering code FV_ _2) electric motor connection with integrated fan - ordering code PF_ _

15 INSTALLATION

Observing a few rules for correct installation is essential to the reliable and proper operation of the gearbox.The rules set out here are intended as a preliminary guide to selecting gearbox.For effective and proper installation, follow the instructions given in the Installation, use and mainte-nance manual available from our Sales network.Following is a brief outline of installation rules:

a) Fastening:– Place the gearbox on a surface providing adequate rigidity. Mating surfaces should be machined and fl at.

– This applies especially to fl ange-mounted gearboxes with splined hollow output shafts (refer to the Installation, Operation and Maintenance Manual available on www.bonfi glioli.com).

– In applications that involve high radial loads at the output end, fl ange mounting is recommended for some gearboxes as this mounting pattern benefi ts from the double pilot diameters provided on these gearboxes (refer to the Installation, Operation and Maintenance Manual available on www.bonfi glioli.com).

– Make sure the gearbox is suitable for the required mounting position.

(35)

(36)

(37)

– Use bolts specifi ed in Use and Maintenance Manual (available on www.bonfi glioli.com) and tighten the bolts to the rated values specifi ed in the relevant charts.

b) Connections– When fi tting transmission elements onto the gearbox do not tap them with hammers or similar tools. To slide these parts in, use the service screws and tappings provided at the shaft ends.Be sure to clean off any grease or rust preventative from the shafts before fi tting any parts.

– Direction of rotationBefore wiring the motor please note the input/output shaft arrangement, as described in the diagram here after:

In line Combined with worm gear unit

Right angle Combined with helical bevel gear unit

(A 17)

RA/RO: For the monodirectional applications or for the applications requiring a sense of rotation pre-vailing on that opposite to it, the selection of "RA/RO" option ensures the declared performance.For applications not requiring a prevailing sense of rotation with respect to each other, the performanc-es are guaranteed regardless of the selected "RA/RO" option.

c) Paint coating– Use paint compatible with the primer applied to the gearbox, see "Supply conditions".Prior to painting, tape the seal rings installed on the shafts. Contact with the solvent may damage the seals with subsequent oil leakage.

d) Lubrication– Prior to commissioning, fi ll the gearbox with the recommended type and quantity of oil (refer to the Installation, Operation and Maintenance Manual available on www.bonfi glioli.com).The level is to be checked through the appropriate plug, or sight glass, each gearbox is provided with, and located according to the mounting position originally specifi ed.

NOTE: Combined gearboxes feature separate lubrication for planetary stages and for worm gears (series 3/V_M) or bevel helical units (series 3/A).The operations described above are not to be performed with life-lubed gearboxes, that are factory fi lled with synthetic oil.

– Use bolts specifi ed in Use and Maintenance Manual (available on www.bonfi glioli.com) and tighten the bolts to the rated values specifi ed in the relevant charts.

b) Connections– When fi tting transmission elements onto the gearbox do not tap them with hammers or similar tools. To slide these parts in, use the service screws and tappings provided at the shaft ends.Be sure to clean off any grease or rust preventative from the shafts before fi tting any parts.

– Direction of rotationBefore wiring the motor please note the input/output shaft arrangement, as described in the diagram here after:

In line Combined with worm gear unit

Right angle Combined with helical bevel gear unit

(A 17)

RA/RO: For the monodirectional applications or for the applications requiring a sense of rotation pre-vailing on that opposite to it, the selection of "RA/RO" option ensures the declared performance.For applications not requiring a prevailing sense of rotation with respect to each other, the performanc-es are guaranteed regardless of the selected "RA/RO" option.

c) Paint coating– Use paint compatible with the primer applied to the gearbox, see "Supply conditions".Prior to painting, tape the seal rings installed on the shafts. Contact with the solvent may damage the seals with subsequent oil leakage.

d) Lubrication– Prior to commissioning, fi ll the gearbox with the recommended type and quantity of oil (refer to the Installation, Operation and Maintenance Manual available on www.bonfi glioli.com).The level is to be checked through the appropriate plug, or sight glass, each gearbox is provided with, and located according to the mounting position originally specifi ed.

NOTE: Combined gearboxes feature separate lubrication for planetary stages and for worm gears (series 3/V_M) or bevel helical units (series 3/A).The operations described above are not to be performed with life-lubed gearboxes, that are factory fi lled with synthetic oil.

Refer to the User's Manual available at www.bonfi glioli.com for indications about checking the oil level and its replacement. Do not mix mineral oils with synthetic oils and/or different brands.However, oil level should be checked at regular intervals and topped up as required.Check monthly if unit operates under intermittent duty, more frequently if duty is continuous.

16.2 Lubrication for 300M series gearboxes

All gearboxes are oil-bath lubricated. For applications calling for gearboxes with a vertically positioned axis, in which oil coverage during operation would not be suffi cient to ensure correct lubrication of upper bearings, suitable life lubrication systems are used.Before start-up, fi ll the gearbox with the correct quantity of oil, selecting the viscosity level
