Why are Hypoid Gearboxes Ideal for Right Angle Applications? June 3, 2014

This example will compare a traditional planetary bevel gearbox (left) with a hypoid gearbox (right), in a 5:1 gear reduction ratio.

Planetary Bevel Gearbox
By construction, a planetary bevel gearbox is the combination of an input bevel gear stage and an output planetary gear stage.  In order to achieve any gear reduction ratio, this type of gearbox always requires two or three gear stages.  In this example, the first stage is a 1:1 bevel gear ratio and the second stage is a 5:1 planetary gear ratio.  For a 3,000 RPM application, the motor speed is continued throughout the entire first gear stage, which means the input bearings and seals, gears, and output bearings and seals are all rotating at 3,000 RPM.  The actual reduction doesn’t occur until the planetary gear stage.  Higher speeds throughout the gearbox means higher heat and can also result in a 50% service life de-rating for continuous applications.

Hypoid Gearbox

A hypoid gearbox on the other hand can achieve up to a 15:1 ratio with only a single gear stage.  In this 3,000 RPM application, the motor speed is immediately reduced to the final reduction speed of 600 RPM which is ideal for the gears, seals, bearings, and shaft.  A lower speed means less heat, which is important to maximizing the life and load carrying capabilities of the output bearings in a gearbox.  GAM’s Dyna Series hypoid gearbox has a 30,000 hour service life rating which is 50% more than a comparable planetary bevel gearbox.  In addition to the performance advantages of using a hypoid gearbox, there is also a substantial space saving benefit. In the example above, GAM’s hypoid gearbox is 46% more compact than the planetary bevel gearbox.

GAM Application Story – Complete Gearbox and Coupling Assembly for Actuator System March 11, 2014

Industry:  Material Handling

Application Challenge:  A customer was looking to drive two ball screws in unison using a single motor and also needed gear reducers to meet the application requirements.  The ball screws were in parallel and positioned eight inches (8”) apart from their centerlines.

GAM Solution: A traditional arrangement for this system would include a center driven dual output shaft gearbox in between two right angle gearboxes and connected using couplings.  However, because the actuators were so close together, this configuration was not possible.  GAM engineers relocated the motor perpendicular to the actuators by using two spiral bevel gearboxes (V-Series) in conjunction with a hollow output inline gear reducer (EPL-H).  All components were assembled together with precision machined adapters and bellows couplings.  The design was approximately twenty percent (20%) shorter than the traditional configuration and used fewer and more economical components resulting in a fifteen percent (15%) reduction in cost.

Typically, the customer would have to size and source the gear reducers from one company, the couplings from another company, design the system, and then ensure that it functions correctly.  Instead, the customer was able to get the complete solution (everything between the motor and actuator) from GAM.   GAM engineers not only sized and selected the appropriate gear reducers and couplings required for the application but also designed the mounting adapters necessary to complete the system.  One 3D model of the assembly was sent to the customer so that all they had to do was drop the file into their design for sign off, which helped to reduce the overall design time.

Results: Single point sourcing. -15% reduction in system cost. -20% reduction in system length. -Eliminated unnecessary components. -Shorter design time.

GAM Linear Mount Products – For everything between the motor and actuator. GAM linear mount products are an innovative line of gearboxes, couplings, and mounting adapters designed to improve the process of connecting motors to actuators.  Whatever the challenge, GAM has the products and design competencies to help with any actuator application.

Gam EPL-H Planetary Gearbox

Gam EPL-H Planetary Gearbox

From Mount Prospect, IL to the International Space Station, GAM is helping to improve the air quality for NASA Astronauts.

Gam’s EPL-H planetary gear reducer is being used for precision valve actuation on a carbon dioxide removal system on the International Space Station.

The EPL-H has a hollow output which was a perfect design feature for the system.  This created the shortest overall length and further reduced mechanical interference with other instruments.

The EPL-H Series  was designed specifically to address the difficulty of connecting gear reducers  to linear products.  The hollow output  and zero backlash clamping ring create the quickest and most economical way to add  gearing to essentially any linear belt or ball screw.   Features include:

  • Precision cut planetary gears
  • Ratios up to 1000:1
  • Frame sizes from 64 mm to 118 mm
  • Same backlash and efficiencies as EPL Series
