2 Features and Benefits Ribbed aluminum housing* provides expanded surface area and greater heat dissipation than traditional cast iron housings. This allows for higher thermal capacity and reduced internal pressure build up. units have two bearings along the input shaft. This helps prevent leaks and increases flexibility in mounting options versus reducers with a bushing on the input. Features and Benefits units are available with standard NEMA motor flange as well as optional IEC motor flanges to fit your needs. units utilize Orings on the input flange and output cover to prevent leaks. Units are sealed more effectively than similar units using paper gaskets. All units come standard as a hollow output bore design with optional plugin shafts. This allows you to lower inventory levels and improve profitability. Due to the improved heat dissipation of the unit, no breather plug or ventilation is required. Our units are sealed for life which greatly reduces the opportunity for outside contaminants to enter lubricant and reduce reducer life. units are available in ratios up to 100:1 in a single reduction stage and 10,000:1 in a double reduction unit. units are painted with high quality epoxy paint. This, along with the aluminum housings, help keep these units free from corrosion. * Units

Size: Ratio: Input Size: Select the size of your reducer by using our selection charts on pages 68. Be sure to select the reducer size that fits the service factor and horsepower requirements of your application. Select the appropriate ratio that will give you your desired output rpm. Input size is based on the motor that will be coupled to the reducer. This only applies to BMQ style reducers. Output Design: The unit comes standard as a hollow output bore ( SM). This unit may also be ordered with a single output shaft ( FMR & FML), double output shaft ( FMD), or as a flange mount design ( FL). Mounting Select the appropriate mounting position from page 13. Position: Accessories: accessories can be found on pages Units which are outside of the standard design should be designated as special and should be submitted for quote. Q uote requests should be accompanied by a detailed explanation of the special characteristics of your requested unit. 4

4 Variodrive Quick Select Guide Using the Variodrive Quick Select Guide Input Service Factor Horsepower Service Factor Ratio Ratio Model Size Input HP Variodrive Quick Select Guide To use the Variodrive Quick Select Guide*: 1. Select the appropriate service factor for your application (see the Superior Gearbox Service Factor Guide on pgs. 2834). 2. Select your input horsepower on the appropriate chart. 3. Read across the selected horsepower line until you get to the ratio of the gearbox that you will be using. 4. Upon reaching the appropriate ratio column you will find the Superior Gearbox Variodrive model number that best suits your selected application. 5. The example above shows how you would select the proper gearbox for an application that requires a 0.25 hp motor and a 50:1 ratio with a 1.0 service factor. The model that would be selected is a size 040 reducer. *The Variodrive Quick Selection Guide is to be used as a selection aid only. The customer is responsible for certifying that the gearbox selected is appropriate for their application. 5

12 Mounting Positions Mounting Positions Note: Mounting a worm gear reducer with the input shaft down ( B8 or V 6) will reduce the life of the input seals due to increased heat and pressure. This can lead to premature seal failure. Superior Gearbox Company always recommends that worm gear units be mounted such that oil pressure on the high speed shaft seal is minimized. Please contact Superior Gearbox Engineering for V 5 or V 6 mount. 13
