» 'RM' version gearboxes are specifically designed for close coupling to industrial diesel engines and are available in either speed increasing or speed reducing format. Gearboxes can be supplied with output shaft either same or opposite rotation to input shaft. Input to the gearbox can be made either by rigid/flexible coupling or via a 'BD' series clutch. The ‘RM’ version gearboxes consist of a 2-piece cast iron casing (*except RM20 units) 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 over-centre clutch in place of coupling, RM-BDS models offer independent mount units with over-centre clutch. » Oil Bath Clutches 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.
