3 General Characteristics HELIAX gear-units have ground helical gears and parallel or orthogonal construction, available in gears ratios and Nm capacity. 1 Gear unit Housing Helimax gear units housing are in ductile iron. or size 65 housing is in welded steel plate. s 16 to 65 have a plit housing construction, allowing easy access to all components and facilitating maintenance. An inspection cover located on top of the gear unit housing allows quick examination of the gear unit parts without disassembling it from the driven machine. Output s The s are made of alloy steel and thermally treated. All seats and output bores are machined to the clearences indicated in this catalogue. Gears Gears are manufactured in high-quality alloy-steel and, after hobbing, subjected to carburizing and quenching treatments. Tooth flanks are ground by the generation process. Bearings Self-aligning spherical roller bearings or tapered roller bearings specifically for the loads indicated. Lubrication Bearings and gears are usually lubricated by immersion or when necessary by oil pump pressure. The bottom of the housing serves as the oil reservoir. Cooling In most cases, the heat radiated by the outer surface is sufficient to maintain the system in a suitable thermal regime. When necessary, a colling coil or external heat-exchanger may be employed for additional cooling. Supply Information Gear units are supplied without lubricating oil. The interior of the box is coated with oil-resistant paint. Shaft ends are protected against corrosion. The gear-units are supplied painted with synthetic enamel, either WEG-CESTARI standard or to client specification. Optional items (on request) - an - Top base for electric motor - Welded steel-plate housing - Labyrinth Seals (Taconite) When high levels of dust are present in the environment the use of labyrinth (Taconite) seals may be necessary in gear units; in this case, the dimensions of the housing center to the tip of the input and to the output (see pages 19-63) may be longer (please consult WEG-CESTARI). 2

7 Selection Guide Lines 3 1) Required information To choose the most appropriate HELIAX gear unit, power to be transmitted, revolutions per minute of the gear-unit input and output s, the type of machine being operated and the operating cycle of the machine should be known. Service actor HELIAX gear-units are calculated for a service factor of 1; i.e. shock-free operation and operating time of up to hours/day at a room temperature of 30 C. The service factor (S), quantifies the influence of external conditions on the operation of the gear unit and depends on the type of operations carried out by the machine being driven. Table 2 (p. 8) indicates different types of load: U (uniform), (moderate shock load) and (heavy shock load) for most common applications. The type of load, the type of engine and the number of hours/day of operation determine the corresponding S in Table 3 (p. 9). 3) Determining the nominal power Nominal or rated power (Pn) is determined by multiplying the effective power absorbed by the machine (Pa) by the Service actor (S). 4) Checking thermal output capacity Permissible thermal output of the gear unit must be checked according to the following formulas: When: Pn = Pa.S PT = PTG.fa.fb.fc.ft (I); use of a complementary cooling system is not necessary; where: PT: permissible thermal capacity PTG: thermal capacity (p. 18) fa: ambient temperature factor, Table 1 (p. 7) fb: duration of operation factor, Table 1 (p. 7) fc: environment factor, Table 1 (p. 7) ft: maximum oil temperature, Table 1 (p. 7). If the previous conditions (I) are not met, check the thermal capacity of the gear-unit with a calling coil: where: PTK: Thermal capacity with calling coil (p. 18). If neither of the previous conditions are met (I and II) a heat exchanger must be used with the gear-unit (in this case, please consult WEG-CESTARI). IPORTANT: a) When the use of a heat exchanger is required, lubrication should be forced. b) When pressure lubrication and a cooling system are necessary, cooling should be by heat exchanger. 5) Selection of gear-unit The gear ratio (i) is obtained by dividing the input rotation (n1) by the output rotation (n. The reduction ratio (i) and the nominal power (Pn) determine the correct gear-unit in the tables on pages 14, 15 and 16. The power of the gear-unit listed in the catalogue must be equal to or greater than the nominal power required as obtained by the formula expressed in item 3, and the thermal power should be checked as in item 4. or rotations (n1) above 0 rpm and below 300 rpm, please consult WEG-CESTARI. or rotations ranging from 300 rpm to 900 rpm, the mechanical power is determined by the following formula: Where: P = Rated power at n rpm P (900) = power at 900 rpm. n = desired rotation (rpm) PT = PTK.fa.fb.fc.ft (II); P = P(900). n 900 6

8 Gear-unit Selection 6) Gear unit selection example A conveyor belt needs to be driven by a gear unit driven by an electric motor. The application has the following characteristics: Gear unit output speed: 26 rpm Electric motor speed: 0 rpm Operating conditions: 12 hours/day 30ºC Absorbed power: kw a) In table 2, page 8 it is found a moderate load classification for a conveyor belt with intermitent load. b) According to table 3, page 9, a moderate load application driven by electric motor for 12 hour/day shall have a service factor of 1.5 c) The nominal power (Pn) will be: Pn = Pt x S = x 1. Pn = 90 kw d) The required gear ratio will be: i = n1 (rpm) = 0 = 69,2 n2 (rpm) 26 e) On page 15 of this catalogue, gear unit size is indicated. Nominal Gear Ratio: i = 71 (3 stages) - exact ratio, refer to page 17, which can transmit 95 kw at 0 rpm. f) Checking thermal output ratings: Condition (I): Pa < PT Where PT = PTG.fa.fb.fc.ft Pa = kw PTG = 5 kw (p.18) (E 3 stages without colling coil) fa = 0.93 (room temperature 30 degrees) fb = 1.00 (continuous service) fc = 1.00 (environment: large enclosed area, air flow >1.4 m / s) ft = 1.00 (oil temperature maximum 95 degrees) < 5 x 0.93 x1.00 x 1.00 x 1.00 < 98 kw: OK Therefore, this application does not require additional cooling. 3 Table 1 actors for Thermal Output Ratings Room temperature in C fa Room-temperature actor actor fa 1,15 1,07 1,00 0,93 0,83 0,75 0,67 fb Operating-time actor % Operating time / hour 1,00 (continuous) 0, 0, 0,40 0,20 actor fb 1,00 1,05 1,15 1,35 1, fc - Environmental actor Types of environment actor fc Open area, air flow > 3.7m / s 1,40 Large enclosed area, air flow > 1.4 m / s 1,00 Restricted enclosed area, air flow > 0.5 m / s 0,75 ft Oil-temperature factor aximum desired oil temperature in C actor ft 85 0, ,00 (requires synthetic oil) see page 67 for recommendations. 1,13 7

On page the admissible overhung loads on the input and output s of the gear-unit may be obtained. Axial loads of up to 30% of the allowable overhung loads can be absorbed simultaneously with the radial loads. The values of the radial loads in the tables refer to the load applied to the center of the length L of the. When the distance of application (x) is different from L/2, there should be a recalculation according to the formulas and tables below: Determining the permissable overhung loads at a point x: (x) D r L/2 a) 1 (x) based on the operating of the bearing: 1(x) = k. r [N] m + x L x b) 2 (x) based on maximum flexion of the : 2(x) = 0.n [N] p + x where: x = distance from the shoulder to the force center [mm] r = radial force acting on the central point of the length from the tip of the L / 2 [N] To determine (x), 1(x) and 2(x) are calculated and the lowest value is chosen to represent (x). 9

The elements mounted on the s must be aligned carefully even if elastic coupling is used. Do not tap the parts into place during assembly as this damages bearings and gear teeth. Suggested arrangement for gear-unit, depending on direction of rotation When direct coupling is not used to connect the gear-unit and machinery, the direction indication in the figures should be observed to avoid traction rupture at the base of the gear-unit. 11

66 Application Instructions for Shrink Disc When selecting a gearbox with shrink disc system please note that the shrink disc must have a service factor (SDS) of at least 2. regarding the input torque to the gearbox, regardless of the gearbox own service factor. The 2. service factor for the shrink disc is necessary to ensure that the gearbox output won t rotate over the driven machine during operation. Due to its starting current peak, electric motors may provide a much larger input torque on the gear unit at the start of the equipment operation, which might generate a transitory torque above the gearbox rated torque, exceeding the limit of the shrink disc and causing the gearbox output to rotate over the driven machine. Next follows the guidelines for succeccful selection of Helimax gear units with shrink disc system. If the standard disc for a particular gear unit size won t suffice to reach the service factor requiremente, a larger disc may be provided as specified on Table7. Examples: Example (1) Load Class: Heavy Operating time: 24 hours / day Required Gear unit Service actor: 2.00 Electric motor: 55 kw / 6 poles / hz Gear ratio: 1 Gear-unit input rotation: n1 = 11 rpm Gear-unit output rotation: n2 = 11/1 = 7.19 rpm Torque at gear-unit output: mot = / 7.19 = Nm An E464 gear unit which has a 1,0,000 Nm nominal output torque, shall have a GEAR UNIT SERVICE ACTOR (S) of 2,32 which meets the mechanical requirementes. Its standard shrink disc torque rates,000 Nm, which has a SHRINK DISC SERVICE ACTOR (SDS) of,000/73,053 = 3,29, suitable for the application (greater than 2.). Example ( Load Class: oderate Operating time: 24 hours / day Required Gear unit Service actor: 1. Electric motor: 15 kw / 4 poles / hz Gear ratio: Gear-unit input rotation: n1 = 17 rpm Gear-unit output rotation: n2 = 17/ = 17. rpm Torque at gear-unit output: mot = / 17. = 8200 Nm An E204 gear unit, which has a 15,0 Nm nominal output torque, shall have a S of 1.89 which meets the mechanical requirements. Its standard shrink disc torque rates 15,0 Nm though, which results in a SDS of 13,0/8,200 = That SDS is not suitable for the application,since it is below 2.. The solution to this problem is either to select a gear unit size 25 with a standard shrink disc that provides a SDS of 3.05 or a gear unit size E23 with a special shrink disc that provides a SDS of 2.45 (considered acceptable). or sizes to 65, please consult Cestari.

68 Lubrication Proper lubrication assures the performance and life of the gear-unit. HELIAX gear-units are lubricated by oil splash and equipped with a oil-level display. The correct oil level is at the center of the display while the gear-unit is not running and is in the working position. Lubrication should be pressuried using a pump for cases marked with () in the power ratings tables (pages 14, 15 and 16) and also for gear-units in the vertical working position. Important a) When the use of a heat exchanger is required, lubrication should be pressuried. b) When pressure lubrication and a cooling system are required, cooling should be via a heat exchanger. Oil Type The lubricant should be good-quality extreme-pressure mineral oil; reaction neutral, non-corrosive to gears and with good antifoaming properties. Oil viscosity depends on the type of gear-unit, angular velocity and ambient temperature. or HELIAX gear-units operating at input rotations between 0 rpm and 0 rpm at an ambient temperature between C and 40 C, oil with viscosity ISO VG 320 is recommended. The table below shows some recommended types of oils and their respective manufacturers: Recommended lubricants: ineral ANUACTURER LUBRICANT VISCOSITY AND TYPE CLASSIICATION VISCOSITY REPSOL / YP Transmision EP 320 OBILOIL obilgear 632 PETROBRÁS Lubrax Industrial EG 320 PS ISO cst à 40 C CASTROL Optigear B 320 VG SHELL Omala 320 TEXACO eropa 320 KLUBER Kluberoil GE1 320 N Recommended lubricants: Synthetic ANUACTURER LUBRICANT VISCOSITY AND TYPE CLASSIICATION VISCOSITY KLUBER Klubersynth EG4 320 OBIL obil SHC 632 PROBRAS Lubrax Syntesys Gear ISO VG320 cst à 40 C Lubricant approximate volume (for reductions from 6.3 to 355 ) liters Operating temperature Operating temperature is the temperature inside the gear-unit after approximately 1 hour working at full load. The normal operating temperature for HELIAX gear-units is between 18 C and 90 C (oil temperature). The external housing temperature is approximately 15 C lower than the operating temperature. 14 Oil Change Oil changes should be performed every 20 hours, although during the first 0 hours oil quality should be monitored and the oil changed if it is contaminated or contains particles. During the oil changes, the oil must be removed while it is still hot in order to facilitate drainage and cleaning. Oil should be replaced using the same type and viscosity as that previously used. Oils of different types or manufacturers should not be mixed. In case of unfavorable environmental conditions (high humidity, aggressive environment, dust) and high temperatures or wide variations in temperature, shorter oil change intervals are recommended. Synthetic oil change intervals are longer and depend on operating temperature: or operating temperatures < C change the oil every 15,000 hours; from C to 85 C every,000 hours; from 85 C to 95 C every 00 hours. 67

69 Cooling System When a cooling system is necessary, it may be of two types: 1 - Drawer-type cooling coil, fixed internally at the bottom of the housing, with entry and exit points of the water positioned on the side of the housing as in the figure below (used for gear-units in the horizontal position). 2 - Heat exchanger of the water-oil type, equipped with pump, filter and pressure gauge. Deposits on the inner walls of the tubes, caused by minerals salts in the water, can be dissolved using Alcalá at a proportion of % in relation to the water volume of the system. The product should be allowed to circulate for 12 hours and then replaced with clean water. As a preventative measure, chemicals additives to the water may be used. These products are manufactured by Kenisur Chemical Ind. Similar products from other manufacturers may also be used.
