ical mill drives Used in vertical coal pulverising applications, David Browns VMX vertical mill drive is the ultimate combination of strength, integrity and precision engineering. Specifically designed to meet the rigorous working conditions of the thermal power industry, our vertical planetary coal pulveriser gearboxes offer outstanding performance in handling the large axial loads and overload conditions normally experienced in power generation applications. At glance Our current VMX series covers all applications from 4kW to 1kW and beyond Input speed is usually based on six pole design but other speeds can be considered Individually tailored to provide an optimised design for specific customer needs enabling flexibility in: Floor mounting positions Input shaft centre height Output coupling diameter Exact ratio requirementsKey features Each model can be tailored to match the requirements of existing mills for drop in replacement to minimise disruption and costs Designed for durability, reliability and low maintenance Transmits power to the mill whilst supporting the grinding table and effectively handling large axial loads Single piece SG iron cast gear case for high strength, integrity and noise deadening characteristics. single piece design removes the risk of oil leakage Heavy duty seals on input shaft and output couplings to increase durability Sun gear self aligns with planet gears and connects to the main bevel shaft through double jointed barrelled gear type couplingGearbox design features Case hardened, profile ground gears for greater precision and durability Self aligning sun gear ensures effective load sharing at all times Thrust pad bearings support main output coupling to transmit thrust loads Labyrinth seals on output shaft and output coupling to prevent dust ingress key fact
