3 Shaft Mounted Reducers Selection GEARBOX SELECTION PROCEDURE (a) Service Factor From Table 1 select the service factor applicable to the drive. (b) Design Power Multiply the absorbed power (or motor power if absorbed power not known) by the service factor chosen in step (a). NOTE: Gear units are momentarily capable of transmitting twice (2x) the rated capacity on start or during operation. (c) Unit Selection Using the value from step (b) refer to the power rating tables on page 6 and select the correct size of unit. The choice of single or double reduction gearbox will be determined by the output speed required. The normal operating speeds for each of the gearboxes may be observed in the power rating and belt drive tables. For other speeds consult your local Authorised Distributor. BELT DRIVE SELECTION Selection of associated belt drive for 1440 rev/min. electric motors (di) Refer to the Drive Selection Tables (pages 13 to 16 and under the appropriate gearbox size and ratio read down the column headed ' ' until an equal or near to that required is found. The suggested ratio is given in the first column. TABLE 1 SERVICE FACTORS (ei) Pulley Diameters Read across from the chosen output speed to obtain both driving and driven pulley pitch diameters, groove section and the appropriate number. NOTE: In many instances one belt is recommended, being adequate for power transmission purposes; where customer preference is for multi-belt drives consult your local Authorised Distributor. (fi) Centre Distance Belt length and centre distance can be found by referring to pages in the Fenner Drive Design Manual, available at (gi)hub Bore Size Refer to the output hub dimensions table on page 7 for the range of bore sizes available. Selection of associated belt drive for driving speeds other than 1440 rev/min. (dii) Gearbox Input Shaft Multiply the gearbox output speed by the exact gear ratio (found in the table on page 9) to obtain the gearbox input shaft speed. (eii) Selection of 'V'-Drive The correct belt drive can now be selected by referring to page 40 in the Fenner Drive Design Manual, availble at NOTE: Wedge belt drives shown on pages 13 to 16 have been selected to give the most economical total drive package for the speed required. If it is necessary to design a special drive it is advisable to consult your local Authorised Distributor.

The prime mover is a 4 kw 1440 rev/min. direct on line start electric motor. A belt drive is required between the motor and gearbox at approximately 700 mm centres running for up to 24 hours/day. SOLUTION Selection Procedure (a) Service factor From Table 1 the service factor is (b) Design Power Using the elevator absorbed power of 3.6 kw. Design Power = 1.25 x 3.6 = 4.5 kw. (c) Unit Selection Using 4,5 kw as the basis for selection reference to the power rating tables (page 246) indicates that an E13 or E20 gear unit will transmit 6.48 kw at 50 rev/min. Selection of associated belt drive (d) A more economic belt drive will be obtained if the 20:1 ratio gearbox is selected, and by reference to page 14 in the gearbox drive tables 50 rev/min. is obtainable. (e) Pulley Diameters On the line giving the output speed of 50 rev/min., read across and note the driving and driven pulley pitch diameters together with the numbers required, which for this case is 106 mm and 150 mm, using 2 XPA Wedge Belts. (f) Belt Selection By reference to page 46 in the Fenner Drive Design Manual (available at com) it can be seen that XPA 1800 belts give 699 mm centres. (e) Available Bores By refering to the output hub bore dimensions table on page 7, it can be seen that the size E is available with a range of bore sizes in both parallel bore and Taper Grip bush. Parallel bore sizes are 55, 50 and 65mm whilst Taper Grip is available in 42mm and 55mm.

8 Shaft Mounted Reducers Taper-Grip R NEW UP-RATED TAPER-GRIP LOCKING SYSTEM Fenner Shaft Mounted Reducers can be secured to the driven shaft by a unique bush locking system which overcomes the difficulties experienced with other methods of mounting, particularly in corrosive environments. The new design includes cap head screws for higher tightening torques and a hardened steel thrust plate. These two new features are responsible for part of the significant torque increase. UP-RATED TAPER-GRIP Transmits 300% more torque Accommodates shaft tolerances to h11. Transmits 300% More Torque Standard bores require no key. Accessible locking arrangement. Reversible bush assembly. Resistant to fretting corrosion. Even easier removal of gear unit. Assembly After the bush is screwed into the hub the reducer can be conveniently positioned on the driven shaft. Locking is effected by sequential tightening of the screws which draw the bush axially against the opposing tapers in the hub thus generating the clamping force along the whole length of the bush in contact with the shaft. Removal The Taper-Grip system offers significant advantages when removing the reducer from the shaft. There is a tendency for Shaft Mounted Reducers, subject to atmospheric or fretting corrosion, to seize solidly onto the shaft, making removal difficult and time-consuming. The Taper-Grip system eliminates this problem, the bush is manufactured from spheroidal graphite iron which not only has similar mechanical properties to steel but has a natural resistance to corrosion and a degree of self-lubricity. This combination of dissimilar materials in contact alleviates fretting corrosion and when the bush screws are loosened and the tapers released there is sufficient clearance within the assembly to permit easy removal. Because the bush is screwed into the hub it is inherently safe. Even if the locking screws are completely removed it cannot inadvertently fall out during reducer handling. Use of smaller than standard bores on Taper-Grip bushes For applications where it is desirable to fit Taper-Grip bushes with bores smaller than the standard catalogue sizes, depending on the size, the torque capacity of the bush may be below the quoted catalogue ratings. In these situations it is preferable to fit a key to the bush/shaft interface. In these cases please consult your local Authorised Distributor. 6 SMSR

9 Shaft Mounted Reducer Motorised Units Motor Mounts A motor mount is available which is designed to fit directly onto either the long edge or the short edge of the Shaft Mounted Reducer. The drive unit can then be located in any position around the shaft to permit easy belt tensioning. The Fenner Motor Mounting Assembly provides a rigid base plate which is designed to accommodate a wide range of motor frame sizes. Each size of motor mount has sufficient adjustment available to ensure that a standard belt can be fitted and re-tensioned as required throughout its working life. Each base plate is supplied with the adjusting screw holes pre-drilled. A drilling template is provided to indicate the size and position of the holes required to suit the motor selected. The template inlcudes fitting/assembly instructions required for the correct mounting of the base plate together with suggested 'trim guides' to reduce the base plate size when using smaller frame motors. To determine the optimum belt length when using a motor mount, first calculate the centre distance as follows: XV/XH min = Motor Frame Size + 'AV/AH min' XV/XH max = Motor Frame Size + 'AV/AH max' A belt length should be selected from pages in the Fenner Drive Design Manual, available at which gives a centre distance equal to or slightly larger then the 'XV/XH min' and smaller than the 'XV/XH max' values determined above.

15 Shaft Mounted Reducers Installation GEARBOX INSTALLATION Satisfactory performance depends on proper installation, lubrication and maintenance. Therefore it is important that the instructions in the Installation and Maintenance leaflet, supplied with each gearbox, are followed carefully. Some of the important aspects of belt and torque-arm installation are listed below. 1. Install pulley on gearbox input shaft as close to the reducer as possible. See fig. 1. Failure to do this will cause excess loads in the input shaft bearings and could cause their premature failure. 2. Install motor and wedge belt drive with the belt pull at approximately 90 o to the centre line between driven and input shafts. See fig. 2. This will permit tensioning of the wedge belt drive with the torque-arm which should preferably be in tension. If output hub runs anti-clockwise, torque arm should be positioned to the right. See fig Install torque-arm fulcrum on a rigid support so that the torque-arm will be at approximately right angles to the centre line through the driven shaft and the torque arm case bolt. See fig. 4. Make sure there is sufficient take up in the turnbuckle for belt tension adjustment. Keep close Fig 2 90 Fig 1 Keep close V-Belt drive may be located to the right if desired The V-Belt Drive may be located in any convenient position. If the Torque-Arm is to be used to tighten the belts, the drive should be at about 90 to a line between the input and output shafts Fig 3 Fig 4 This angle should be a right angle but may vary up to a maximum of 15 0 either way If output hub rotates clock-wise, position the Belt drive and Torque arm in the opposite direction to that shown in the illustration Torque arm and belt take-up Torque arm may be located to the right if desired SMSR 13

18 Shaft Mounted Reducers Lubrication LUBRICATION QUANTITIES & RECOMMENDED GRADES Fenner Power Plus Shaft Mounted Reducers are dispatched without oil. Before running they should be filled with an appropriate amount of lubricant as shown in the tables, dependent on the mounting position. Fill to level plug when reducer is not running. Drain, flush and refill every six months of operation, check oil level regularly MOUNTING POSITIONS Position of filler, breather and drain plug for different mounting positions are shown in fig. 1. CAUTION. Too much oil will cause over-heating. Too Little oil will cause gear and bearing failure. Normal operating position are shown in fig 1. Note that the reducer is supplied with four plugs. After the reducer has been mounted in its running position the plugs must be located as shown in fig 1 for the appropriate mounting position. If the reducer is not within 20 degrees of one of the position shown, the oil level plug cannot be safely used to check the oil level. This can be overcome by disconnecting the torque-arm and swinging the reducer around to one of the positions shown. Because of the many positions of fitting the reducer it may be necessary or desirable to make special adaptions using the plug holes in the reducer with standard pipe fittings standpipes or oil level gauges, consult your local Authorised Distributor. Units are fitted with filler, level and drain plugs generally in the position shown.
