    [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.

    What Is the Difference Between a Single and Double Acting Hydraulic or Pneumatic Cylinder?

    Posted by Troy Branham on Nov 16 ,2016

    If you need power, there’s nothing like a hydraulic cylinder to deliver a big punch. It’s the workhorse of the industrial world for the heaviest lifters and movers, including bulldozers and dump trucks. Hydraulic cylinders are commonly used in mobile applications. Hydraulic cylinder bore sizes can range from a few inches to several feet in diameter.

    Pneumatic cylinders are typically used on industrial machinery and rely on compressed air pressure from 15-110 psi. Pneumatic cylinders tend to have less overall cost associated when compared to hydraulic cylinders. Pneumatic cylinders have more main body choices which include extruded aluminum profiles for easier integration into machinery.

    Designing around them requires knowledge of pressure, force, and safety considerations. But it all starts with understanding the difference between a single and double acting hydraulic cylinder.

    [VIDEO] What is a Brake Caliper and How Does it Work?

    Posted by Chad Randleman on Nov 9 ,2016

     A brake caliper is a device used to either stop or hold a rotating mass. It's designed to absorb the energy created by the rotating mass, and dissipate it as heat. This video blog gives you a quick look at the different styles and highlights their main functions.

    [VIDEO] A Closer Look into the Two Types of Wind Turbine Brakes

    Posted by Peter Wold on Oct 26 ,2016

    To operate properly, wind turbines need two types of brakes — one to control the rotor speed to protect the system, and another to keep the turbine facing into the wind. W.C. Branham Sales Manager Pete Wold looks at your options for the two types of wind turbine brakes in this edition of Solutions in Motion.

    What to Ask When Applying Pneumatic Rod Cylinders to a Mechanical Design

    Posted by Troy Branham on Oct 19 ,2016

    There is no doubt that when designing a complex piece of specialized equipment pneumatic rod cylinders have a lot of advantages. For one, there is no better way to pack a big punch in a small package when you need it. However, it’s not like one size fits all. You need to find the right fit for your application, so these are a few key questions to ask when applying pneumatic rod cylinders to your mechanical design.

    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.

    Proper Maintenance for Your Rodless Cable Pneumatic Cylinder

    Posted by Troy Branham on Sep 28 ,2016

    Rodless cable pneumatic cylinders are very useful for many applications because they save space. With no rod to extend or retract, rodless cable cylinders stroke along their own body length. So they save valuable machine space because they are almost half the overall length of a comparable rod cylinder while producing the same, if not more, punch.

    W.C. Branham manufactures all of our cable pneumatic cylinders using the highest quality of materials and workmanship. From Mil-Spec rated cables which provide millions of continuous cycles to 6063T6 aluminum hard coated I.D. and O.D. tubing to sheaves made from high strength aluminum and superior sealing, you can count on them to provide reliable operation with minimal maintenance for years.

    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.
