P1 (KW1) - Power applied to reduction gear set up with motorflange (FRD) according to unified standards.

Pu (KW) – Output power transmitted by reduction gear,calculated with:

1.4 GEAR RATIOi – Value required to identify the reduction gear:

it – Total gear ratio for the combined reduction gear, given by:it = i1 x i2

i1 – Driving reduction gear ratioi2 – Driven reduction gear ratioic – Pretorque reduction gear ratioitc – Total reduction gear ratio of pretorque, given by:

itc = ic x i

1.5 TWISTING MOMENTM1 – Output torque transmitted by reduction gear (RD) with auniform load with reference to input velocity n1, and outputvelocity n2, calculated with a service factor S = 1.

M1’ - Output torque transmitted by reduction gear (FRD) withreference to the motor applied.

M2 – Torque required by the application; it must always belower than the value of M1.

Mc – Torque value to be used to select the reduction gear,calculated as follows:

Mc = M2 x Fs must be < M1The torque value Mc must be adjusted by the factor Ft, whichis given by the combination ambient temperature and type ofload:

Mc = M2 x Fs x Ft < M1

1.6 EFFICIENCYRd – Dynamic efficiency determined by output power (Pu) and input power (P). Other factors determined in the Rd calculation are: rateof slide, type of lubrication and helix angle of gear mesh.N.B. The optimal efficiency value is obtained after an initial running-in period.

Rs – Efficiency at time of reduction gear start-up, which varies according to the gear ratio. The choice of motor is therefore important,especially when intermittent applications are involved.

The values are shown in the performance table.

1.7 IRREVERSIBILITYThe reversibility of a reduction gear is determined by a high mesh angle (favoring low ratios), while irreversibility is determined by a lowhelix angle (high ratios 1/70, 1/80, 1/100), and also by the type of load and any impact.

Static irreversibility – This is the state in which it is not possible to have rotation of the low speed shaft. Only in particular conditionsand when loads are subject to vibrations might a very slow return occur. The lower the value of Rs, the greater the irreversibility willbe. Theoretically, the conditions are as follows:Rs < 0.45 there is irreversibilityRs 0.45-0.55 irreversibility uncertainRs > 0.55 there is reversibility

Dynamic irreversibility – This is the condition required to stop and therefore hold the load at the moment the drive action ceases.This is the most difficult condition to achieve because it is influenced by the efficiency Rd, by the rotation velocity and by possiblevibrations that may be generated by the load. Theoretically, the following indications can be given:Rd < 0.5 there is dynamic irreversibilityRd > 0.5 there is dynamic reversibilityThe table shows the degree of reversibility versus gear ratio.

NB – Since total irreversibility cannot be assured, the mechanism must be provided with an external braking action.

1.8 SERVICE FACTORFs – Value that takes into account the various operating states (start-up frequency, nature of load and duration) to which the reductiongear is subjected; the power ratings and twisting moments indicated in the reduction gear (RD) performance tables are nominal, i.e.valid for a service factor Fs = 1, and they correspond to the service factor given in the table, for reduction gears set up with motorflange (FRD).

1.9 RADIAL LOAD (CR) and AXIAL LOAD (CA)CR – Every type of transmission generates radial loads both in the input shaft (high speed) and in the output shaft (low speed). Thevalues in the tables have been calculated for a force acting midway along the projecting shaft; for a load positioned at 1/3 of the length,increase the table values by 25%; for a load positioned at 2/3 of the length, reduce the values by 25%.

CA – The Axial Load values (CA for low speed shaft, CAV for high speed shaft) are 20% of the Radial Load values.For shafts projecting at both ends, each end can support a load equal to 3/5 of the values shown in the table, provided they move inthe same direction and have the same intensity.We recommend that the chain wheel, gear or pulley be installed as close as possible to the shaft stop.

The values in the tables are expressed in daN.

1.10 LUBRICATIONOur reduction gears are supplied life-lubricated with synthetic oil. However a plug is fitted for use if necessary. Unless specificrequests are made, the type of oil used is “TIVELA OIL SC 320”.

1.11 INSTALLATIONIt is important to secure the motor reduction gear so that vibrations are not transmitted during operation, because they are a source ofnoise and premature wear due to variable fatigue. With regard to continuous starts under load, we recommend that the motor beprotected with thermal probes so that overheating due to overloads does not lead to coil meltdown.

1.12 PAINTINGUp to and including size 70, the reduction gears are made from aluminum and no painting of any kind is provided.From size 85 up, the reduction gears are made from cast iron and painted.For paint specification requests, please contact our Special Products Department.

1.13 MAINTENANCESince our reduction gears are supplied with life-lubricated synthetic oil, no particular maintenance is required apart from externalcleaning. Do not use solvents for cleaning as they may damage the seal rings and gaskets.

1.14 TECHNICAL SPECIFICATIONSTechnical specifications shown in this catalog are subject to change without notification. Please contact our customer service team forthe most current information.

1.15 WARRANTYThere are no warranties, of merchantability, fitness for purpose, or express, that extend beyond the description contained herein. Theparties agree that the buyer’s sole exclusive remedy against the seller shall be repair or replacement of defective parts of goods. Thebuyer agrees that no other remedy, including, but not limited to, consequential and incidental damages, shall be available to him.



AMETRIC® gearboxes are appreciated for their reliability and noise-free operation, which are crucial characteristics of a good product.This has been achieved by the systematic control of processes, from selecting the materials right through to assembly, every singlephase of which is performed manually by trained personnel.

Up to and including size 70, the external parts (box, flanges, feet, etc.) are made from SGALSI 91 UNI 7369 aluminum. From size 85 upthey are made from mechanical cast iron G20-UNI 5007.

•TRANSMISSION MECHANISMUp to size 50, there are 11 gear ratios: for sizes 63, 70 and 85 there are 14 gear ratios (personalized gear ratios can be considered onrequest).

•WORM GEARSMade from nickel-chrome-molybdenum steel and case hardened to obtain a specific surface hardness (ensuring long life and wearstrength) and a tough, elastic core to withstand mechanical impact. The profile is ground to an involute shape (Z1).

•CROWN GEARSBuilt with central hub in cast iron (G20-UNI 5007), onto which a bronze layer is cast (B14-UNI 1701).

•BEARINGSBall type with wide face; from center distance 50 taper roller bearings are mounted on the high speed shaft (WORM GEAR).

•SEAL RINGSDouble lip seal rings are fitted on all types to ensure enhanced tightness.

The technical and structural characteristics are the same as those of the worm gearboxes. Product quality is the result of meticulousmachining processes and specific controls during manufacture. Assembly is carried out by competent, quality-conscious personnel.Combinations and gear ratios not shown in the tables can also be obtained; it should be borne in mind that beyond certain ratios (2500and over), the structural modulus of the worm gear plus crown gear pairing diminishes considerably, making a technical inspectionnecessary prior to proceeding with the application. Our Special Products Department is on hand to assist with any requirements.

In this case too, the technical and structural characteristics are the same as those of the worm gearboxes and worm gear motors. Wehave adopted a structural system whereby we can supply a PAM type closed gear motor with primary reduction without having tosupply the motor pre-mounted. The customer is free to choose the motor he wants, and to fit it in the same way as on a normal PAMgearbox. In the performance tables (PRD) only gear ratios from 1 to 3 are shown, though higher ratios can be provided on request.
