Description These units are free standing clutches of the multiple plate, oil bath type. These clutches are particularly suited to arduous applications and are capable of withstanding high radial loads. The PFI 60 and PFI 120 are manufactured with input and output shafts. The PFI 60P and PFI120P are intended for hydraulic pump direct connection with the same pump adaptor flanges and couplings as on AM 230 - 450 pump drives which means the possibility to fit a large number of pumps with standard components. Clutches & Gearboxes Technical Data Oil Bath Clutches 1 PFI 60 Power curve P.T.O. selection is to be made by multiplying the net input power by the service factor: 1.0 for centrifugal pumps, 1.3 for hydraulic pumps, 1.5 for direct winch drives, 2.0 for crushers. The resulting power is to be below the line on the graph. PFI 120 Power curve P.T.O. selection is to be made by multiplying the net input power by the service factor: 1.0 for centrifugal pumps, 1.3 for hydraulic pumps, 1.5 for direct winch drives, 2.0 for crushers. The resulting power is to be below the line on the graph.

Description Type BD clutches have been designed to mount onto any engine with flywheel and bellhousing conforming to SAE dimensions. These clutches consist of an overcentre clutch assembly mounted onto a tapered shaft carried on two bearings. The pilot bearing is housed in the engine flywheel and the outer bearing serves to support the output shaft and is capable of withstanding radial loads as detailed within this catalogue. For exceptionally high radial loads models BD290/150R, BD2200R and BD3300R are available with special heavy duty bearings. Power is transmitted by clutch plates located within a driving ring bolted to the engine flywheel. The clutch mechanism is equipped with a unique automatic clutch adjustment device capable of compensating for reasonable clutch plate wear. Type BDS units provide a unique range of free-standing clutches intended for applications where engine mounting is not possible. BDS clutches consist of a BD type clutch but with a drive plate supported on the input shaft carried on two bearings in the independent bellhousing. The drive plate carries the driving ring and main shaft pilot bearing. BDP and BDSP clutch units are constructed as per the standard type BD and BDS clutches, but offer a selection of hydraulic pump adaptors in place of output shaft. Selection BD clutches must initially be selected to match the available SAE flywheel and housing offered on the diesel prime mover. Subsequent study must be made to ensure that the clutch unit selected is capable of offering sufficient torque capacity to provide the service factor recommended for the application. Please note that the maximum torque figures published in our literature do not include a service factor. Clutch selection must take the following into account: 1. Type of prime mover. 2. Inertia of machine to be driven. 3. Peak torque requirement of machine. 4. Number of clutch engagements per hour and duration of engagement. The tables below will assist with selection. Table A gives the service factor according to prime mover and application. Multiply input HP by this factor, and when applied to Table B, taking account of input RPM and the corrected input HP, the clutch selected must appear to the right of the convergence point.

Clutches & Gearboxes BD Engine Mounted Clutches 7 All dimensions in mm. unless otherwise stated. Outrigger Bearing Housings For applications demanding high radial loads, such as ‘’V’’ belt drives etc., JBJ offer a range of outrigger bearing housings. These outriggers transfer the radial load from the engine rear main bearing to the shaft support bearing located in the housing. Most outrigger housings consist of type BD overcentre bellhousing and input shaft, with coupling in place of clutch, and therefore closely resemble BD units, but without operating lever. Overall, and shaft dimensions are per the equivalent BD clutch unit. Some special versions with reduced overall length may be offered.

Clutches & Gearboxes RM Speed Increasing/Reducing Gearboxes 11 Dimensions RM gearboxes consist of a 2-piece cast iron casing* with helical teeth, case hardened gears and shafts. Reverse rotation units have a primary gear on the input shaft driving directly onto the secondary gear powering the output shaft. Same rotation versions have an idler gear between primary and secondary gears. There are 3 basic types of RM gearbox; RM-GR models are for close coupling to diesel prime movers and have a choice of SAE housing and rigid or flexible couplings; RM-BD models are similar to RM-GR but are fitted within an overcentre clutch in place of coupling, RM-BDS models offer independent mount units with overcentre clutch. Selection The power and torque capacity of the unit will vary according to the selected ratio. The published maximum torque figure is the theoretical permissible limit for operation during a 5000 hour period at an input speed of 2000 rpm. The maximum engine kW indicates the power that may be transmitted under normal conditions without an oil cooling system. These limits give merely an indication and ignore such factors as ambient temperature, air circulation, application, etc. RM unit selection should be made by taking input torque, and by multiplying it by the service factor applicable to the application. Examples of service factors are shown below. Service Factors 1 - Light duty : centrifugal pumps, fans, etc. 1.2 - Medium duty : 4 cylinder compressors, conveyors, hydraulic pumps, marine applications 1.5 - Heavy duty : 2 cylinder compressors, presses, cement mixers 2 - Very heavy duty : 1 cylinder compressors, mills The above factors apply only to RM gearbox units. For clutch/gearbox combinations study also the clutch service factor and maximum power/torque limitation. For assistance contact jbj technical department, telephone: 01737 767493 or email: firstname.lastname@example.org Installation The RM-GR & RM-BD units have been specially designed for close coupling to industrial diesel engines and consequently are constructed with a single support bearing on the input shaft and must therefore utilise the pilot bearing available on most engines. Pilot bearings can be supplied if required. When installing an RM-BDS unit take care to mount unit with shaft axis horizontal and on common base with prime mover. Satisfactory alignment between drive coupling and input shaft should be achieved in order to avoid axial and radial loads on the input shaft. RM units may be ordered with output shaft rotated through various positions to suit customer applications. Please contact jbj technical department, telephone: 01737 767493 or email: email@example.com for confirmation. Lubrication RM units are supplied without oil. Before use fill to maximum mark on dipstick. EP90 gear oil such as BP ENERGOL CS150 is recommended. The lubricant must be replaced after the first 100 hours use. Subsequent oil changes should be made every 1000 hours dependent upon the application, or every 12 months, whichever is the sooner. Eficiency Reverse rotation - RM “D” units offer 97% Same rotation - RM “S” units offer 95% * Except RM20 units
Clutches & Gearboxes RM Speed Increasing Gearboxes 13 The formula shown in the illustration will enable the radial loading to be calculated. The figure should be compared with the maximum allowable radial loads shown against distance (x) in the chart. Oil capacity will vary slightly according to ratio and wil increase if RM unit is fitted with cooling system. Some special ratios are available upon request. For heavy duty applications types RM 120 and RM 150 gearboxes are prepared to accept an oil circulation pump which permits the use of a heat exchanger to keep the oil temperature at an acceptable level. Use SAE 90 lubricant in these speed reduction and multiplier gearboxes.

Clutches & Gearboxes RM Speed Increasing/Reducing Gearboxes 14 RM-BD, RM-GE, RM-GR Dimensions The dimensions shown apply to RM units with either type BD overcentre clutch, flexible or rigid coupling. RM units with output shaft in 9 o’clock position (facing shaft) are available upon request. Some other RM+BD combinations are offered. Certain RM models may be obtained with hydraulic pump adaptor in place of output shaft. For details contact jbj technical department, telephone: 01737 767493 or email: firstname.lastname@example.org
