Additionally, unit feet are available for mounting on a baseplate with motor and coupling, the complete assembly being mounted on the driven machine shaft extension and connected to the foundation by a torque arm. Shaft mounted units are fitted with a 'shrink disc' device to provide positive clamping on the driven machine shaft extension. It is positioned on the input side of the gear unit. Shaft mounted units with KIBO bushes may also be supplied for fitting on to a keyed shaft. KIBO bushings make the gear unit easier to mount onto the shaft, eliminating fretting corrosion ensuring easy dismounting. otorised Gear nits Gear units are available as standard assemblies comprising IEC standard metric (B5) flanged and NEA 'C' motors directly mounted on the gearcase input shaft housings by adaptors. otor and gear unit shafts are connected by flexible couplings. Baseplates Standard baseplates can be supplied for units with parallel or right angle shafts. Assemblies comprise of gear units and foot mounted motors correctly aligned in manufacture and connected by our couplings. Coupling guards are fitted. Baseplates for right angle shaft gear units are designed for use with either foot or shaft mounted arrangements, and provision is made for attaching torque arms where required. Designs provide ample stiffness to prevent distortion under load. Full details are available from our Application Engineers. Backstops Externally mounted Backstops can be fitted to all Series G gear units, when required to operate in nonreversing drives. They are located on the helical pinion shaft and have adequate capacities to deal with full rated torques. All backstops are centrifugal lift off type. Changing the direction of locking rotation is a simple operation. If required, a torque limiting backstop with controllable tension release can be fitted to all units (consult our Application Engineers). Preservation / Protection Series G gear units are despatched without oil. Prior to despatch they are test run with a rust preventative oil giving adequate protection to internal parts for a period of six months covering normal transport and covered storage. Shaft extensions and hollow output shafts are protected with a rust inhibitor which is proof against sea water and suitable for under-cover storage up to 2 months. Note: Where gear units are to operate in abnormal conditions, or where they are to stand for long periods without running, eg in plant installation, we must be notified so that suitable protective arrangements can be made. 3

8 EXPLANATION AND SE OF RATINGS AND ASSOCIATED RATING FACTORS 005 Gear unit selection is made by comparing actual loads with catalogue ratings. Catalogue ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalogue ratings. i.e. Equivalent Load = Actual Load x Service Factor echanical and Thermal Service Factor must be considered:- echanical Service Factors Fm and Fs Thermal Service Factors Ft, Fd, Fh and Fv echanical ratings and service factors Fm and Fs echanical ratings measure capacity in terms of life and/or strength, assuming 0 hr/day continuous running under uniform load conditions. Catalogue ratings allow 00% overload at starting, braking or momentarily during operation up to 0 times per day. The unit selected must therefore have a catalogue rating at least equal to half maximum overload. echanical Service Factor Fm (Table ) is used to modify the actual load according to daily operating time, and type of loading. Required mechanical power rating P(mech) = absorbed power x Fm Load characteristics for a wide range of applications are detailed in Table 3 opposite, which are used in deciding the appropriate Service Factor Fm from Table. If loading can be calculated, or accurately assessed, actual loads should be used instead modifying using Fm. For units subject to torque reversal or frequent stop/start overloads in excess of 0 times per day, the following check should be made gear unit input power capacity (kw) > Tm x Fs x n 2 x 9550 Where Tm = motor starting torque (Nm) or rating of torque limiting device, fluid coupling etc n = input speed (rev/min) Fs = number of starts factor (See table 2) For applications where high inertia loads are involved e.g. crane travel drives, slewing motion etc, or when units are to operate in extremely dusty or moist/humid atmospheres, unit selection should be referred to our Application Engineers.

10 990 Thermal ratings and service factors EXPLANATION AND SE OF RATINGS AND ASSOCIATED RATING FACTORS The Thermal ratings are a measure of the gear units ability to dissipate heat. If they are exceeded the lubricant may overheat and breakdown, resulting in gear failure. Thermal ratings are given on page 32 for parallel shaft units and page 46 for right angle shaft units. The following choices are available: i) No additional cooling ii) nit fitted with fan cooling iii) nit fitted with water cooling coil iv) nit fitted with cooling coil and fan Catalogue thermal limitations are based on the unit operating continuously in an environment with an ambient temperature equal to 20 o C and in a horizontal mounting position. The thermal rating is affected by ambient temperature, duration of running per hour, altitude and operating area. To account for these varying conditions, the service factors given in tables 4, 5, 6 and 7 should be applied as follows:- Ptherm = Absorbed Power Ft x Fd x Fh x Fv Ptherm = Required thermal rating (kw) Ft = Service factor for ambient temperature (see Table 4) Fd = Service factor for intermittent duty (see Table 5) Fh = Thermal service factor for altitude (see Table 6) Fv = Thermal service factor for air velocity correction (operating area) (see Table 7) Table 4.

22 0202 OVERNG & AXIAL LOADS ON SAFTS aximum permissible overhung loads When a sprocket, gear etc. is mounted on the shaft a calculation, as below, must be made to determine the overhung load on the shaft, and the results compared to the maximum permissible overhung loads tabulated. Overhung loads can be reduced by increasing the diameter of the sprocket, gear, etc. If the maximum permissible overhung load is exceeded, the sprocket, gear, etc. should be mounted on a separate shaft, flexibly coupled and supported in its own bearings, or the gear unit shaft should be extended to run in an outboard bearing. Alternatively, a larger gear is often a less expensive solution. Permissible overhung loads vary according to the direction of rotation. The values tabulated are for the most unfavourable direction with the unit transmitting full rated power and the load P applied midway along the shaft extension. ence they can sometimes be increased for a more favourable direction of rotation, or if the power transmitted is less than the rated capacity of the gear unit, or if the load is applied nearer to the gear unit case. Refer to our Application Engineers for further details. In any event, the sprocket, gear etc. should be positioned as close as possible to the gear unit case in order to reduce bearing loads and shaft stresses, and to prolong life. All units will accept 00% momentary overload on stated capacities. Overhung load (Newtons) P = kw x 9,500,000 x K N x R where P = equivalent overhung load (Newtons) kw = power transmitted by the shaft (kilowatts) N = speed of shaft (rev/min) R = pitch radius of sprocket, etc. (mm) K = factor Note: Newton = kg = lbs.

The values tabulated are for the most unfavourable direction and hence can sometimes be increased. Similarly they can sometimes be increased if the power transmitted is less than the rated capacity of the gear unit. Thrust capacities tabulated refer to outputshafts, and are calculated without any overhung loads being applied. In cases where combined axial thrusts and overhung loads are to be applied, refer to our Application Engineers. 9

24 0202 To calculate the Bending oment on the gearbox output shaft using the method recommended in The Engineering Equipment sers' Association andbook No. 9:- Bending oment = Absorbed Power (kw) x 9.5 x L = knm Shaft Speed x 0.75 R The above information is given for guidance. When more precise bending moment values are available they should be used. AGITATOR APPLICATIONS BENDING OENT CAPACITY Check the Bending oment Capacity of the Gearbox Agitator units are suitable for supporting a paddle directly coupled to the gearbox output shaft and for accepting the bending moments and axial thrusts generated from the forces at the paddle. Agitator type units have an extended bearing span and taper bearings to accept higher loads than the standard unit. Check the Bending oment Capacity limited by shaft stress, using Table 2. Output Torque (Nm) L metres Check the Bending oment Capacity limited by bearing life, using Table 3. R metres Note: Bearing Capacities are based on 0,000 hours, L0 life. For other bearing lives multiply the values in Table 3 by the factors in Table.
