Variodrive Quick Select Guide

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.
  • Variodrive 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.
  • Variodrive units are available with standard NEMA motor flange as well as optional IEC motor flanges to fit your needs.
  • Variodrive units utilize O-rings on the input flange and output cover to prevent leaks.
  • Units are sealed more effectively than similar units using paper gaskets.
  • All Variodrive units come standard as a hollow output bore design with optional plug-in shafts. This allows you to lower inventory levels and improve profitability.
  • Due to the improved heat dissipation of the Variodrive 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.
  • Variodrive units are available in ratios up to 100:1 in a single reduction stage and 10,000:1 in a double reduction unit.
  • Variodrive units are painted with high-quality epoxy paint. This, along with the aluminum housings, help keep these units free from corrosion.
  • Designed to be directly interchangeable with most industry-standard NMRV and NRV models.

Model: Your Variodrive model is based on whether you require the reducer to be direct coupled to a motor (BMQ) or will be driving the reducer via an external input shaft (B).
Size: Select the size of your Variodrive reducer by using our quick selection guide below. Be sure to select the reducer size that fits the service factor and horsepower requirements of your application.
Ratio: Select the appropriate ratio that will give you your desired output rpm.
Input Size: Input size is based on the motor that will be coupled to the reducer. This only applies to BMQ style reducers.
Output Design: The Variodrive 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 Position: Select the appropriate Variodrive mounting position.
Accessories: Variodrive accessories can be found on pages 14-15. Units that are outside of the standard Variodrive design should be designated as “special” and should be submitted for quote.

* Interchangeable with most NMRV industry-standard models.

** Interchangeable with most NRV industry-standard models.

 

Quote requests should be accompanied by a detailed explanation of the special characteristics of your requested unit.


Determine Your Service Factor


Determine Size Needed

To use the Variodrive Quick Select Guide*:

  1. Once you have determined the appropriate service factor using the service factor guide above,  use the drop-down box below to reveal the correct table based on the service factor you identified.  
  2. In the table, locate 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. Click Here to view an example that 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.

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.
