DESIGN FEATURES Shaft Mounted Units Shaft mounted units can be mounted on the driven machine shaft extension and connected to the foundation by a torque arm, supplied as an optional extra. 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...

DESIGN FEATURES High quality alloy case hardening materials provide long life wear resistance and fatigue strength. Profile ground single helical gears and hard finished spiral bevel gears ensure high standards of accuracy, surface finish and quiet running characteristics. Helical gears are fitted in parallel shaft units. Units with shafts at right angles incorporate spiral bevel and helical gears. Standard gearcases are of rigid cast iron construction with modern styling, special cases can be supplied as SG iron or fabricated steel. Horizontal split case design for ease of maintenance....

AND ASSOCIATED RATING FACTORS 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 Mechanical and Thermal Service Factor must be considered:- Mechanical Service Factors Fm and Fs Thermal Service Factors Ft, Fd, Fh and Fv Mechanical ratings and service factors Fm and Fs...

AND ASSOCIATED RATING FACTORS Thermal ratings and service 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 ii) Unit fitted with fan cooling iii) Unit fitted with water cooling coil iv) Unit fitted with cooling coil and fan Catalogue thermal limitations are based on the unit operating continuously in an environment with an ambient...
