    [VIDEO] A Deep Dive into W.C. Branham's Right Angle Gear Drive Product Line

    Posted by Troy Branham on Dec 7 ,2016

    W.C. Branham was industry-first with right angle hollow bore helical gearboxes that package an all ball bearing configuration in a leak-proof, sealed gearcase with a pre-lubricated design. The immediate benefits were achieving higher thrust and radial loads, lower operating temperature for greater efficiency, no leakage, and longer service life.

    What is a Worm Gear Set and What Does it Consist Of?

    Posted by Troy Branham on Nov 30 ,2016

    A worm gear set actually looks a lot like it sounds — there's a worm that drives a gear. The worm — a shaft with a spiral thread — engages with and drives the gear — a toothed wheel. The worm screw and worm wheel are aligned at a 90-degree angle, forming the simplest kind of right angle gearbox. In fact, a worm gear was one of the original six simple machines. No matter how simple, though, the worm gear is an effective, time-honored way to manage power and torque.

    Uses for Worm Gears

    Worm drives create a compact means to substantially decrease speed and increase torque.A worm gear can have a massive reduction ratio with little effort — by simply adding more circumference to the wheel. That technique can either greatly increase the torque, or greatly reduce the speed. By comparison, it would take multiple reductions of a conventional gear set to achieve the same results — so worm gears have fewer moving parts and fewer places for failure.

    Everything You Need to Know About Spiral Bevel Gear Design

    Posted by Peter Wold on Oct 12 ,2016

    Where they were once an expensive and difficult configuration to make, gearboxes today can be made from spiral bevel gears. The precision necessary to craft such beautiful and intricate pieces is still tricky, but with the right attention to design and fabrication, their many benefits can be had by all. In order to fully appreciate their many advantages, here is everything you need to know about spiral bevel gear design.

    The most common form of this kind of gearbox is a differential, like that found in a car. That is a much more complicated design which allows each wheel to turn at different rates. It also relies on a pinion and ring gear assembly, where the driving and driven gears are very different in size. But the simplest form of a right angle gearbox uses the same elegant spiral bevel gear cut with gears much more similar in diameter and number of teeth.

    The gears in a spiral bevel gear design are cut in a helix, which is very complicated and intricate. Before computer controlled machines, it took an expert machinist many hours to be able to craft gears like this from raw stock. The helical cut runs either clockwise (right hand) or counter-clockwise (left hand). For this reason, they always have designed, fabricated, and used in pairs. A gearbox, once fabricated, should be considered sealed.

    5 Common Right Angle Gear Drive Lubrication Options

    Posted by Troy Branham on Oct 5 ,2016

    In any complex mechanical machine, all of the parts represent a chance for failure if they are not designed or maintained properly. Sometimes the simplest parts get overlooked. A right angle gearbox needs less attention than many more complex parts, but it still can bind, grind or fail if it does not have the proper lubrication. Here are five common right angle gear drive lubrication options for proper installation and maintenance depending on your particular operating conditions.

    1. Gearing Type

    The internal speeds of your right angle gearbox vary with the type of gears operating in them. Each requires a different type of lubricant in order to perform properly. Spur and bevel gears use a low speed and low slide lubricant. Helical or spiral bevel gears are medium slide and medium speed. Worn gears always operate with high or excessive sliding, with very high loads.

    The manufacturer will usually recommend the proper lubrication for the type of gears in the right angle gearbox for normal loads.

    Right Angle Gearboxes: Does My Design Call for a Right or Left-Hand Rotation?

    Posted by Troy Branham on Sep 21 ,2016

    Right angle gearboxes are used throughout dozens of industries in hundreds of applications that require a reliable transfer of speed or power. They're versatile, but the name can be a bit of a misnomer — the “right” in "right angle" comes from their 90-degree angle — but they can be right- or left-facing. If your application demands a right angle gearbox, it’s important to know if your design calls for a left-hand or right-hand rotation.

    Right-Hand or Left-Hand Rotation

    The main differentiation between the right-hand and left-hand versions of right angle gearboxes is the rotation of the gear drives.

    For example, a bottom gear in both left- and right-hand rotations turning clockwise would have the top gear turning counterclockwise for left-hand rotation, and clockwise in the right-hand rotation.

    With many standard types and sizes are available, and the ability for specialty shaft configurations, ensuring the right angle gearbox for your application is key. Having multiple mounting options also helps simplify your design considerations.

    Which Right Angle Gearbox Will Work Best for Your Mechanical Design

    Posted by Troy Branham on Jul 7 ,2016

    Within the world of gearboxes, there are so many configurations that choosing the right product for your particular mechanical design can be challenging. Nowadays, custom gearboxes are more and more common, chiefly because manufacturing to specification is easier than ever, with newer machine tools as well as design and automation software. So, when determining the right angle gearbox that will work best for your mechanical design, it’s important to identify the key aspects of your design and application.
