Sierramotion Guest Post: What Coupling Should I Use?
There are many options to connect two rotating shafts together. The most obvious path is to use a rotary coupling. Unfortunately, while there are many couplings that can be purchased or made, choosing the right one takes some practice and a little bit of luck.
Video: Direct Drive Motors & Precision Gearing
Robots have evolved from moving big things around in large areas to working collaboratively with humans in tight or uncaged environments. Robot designers are continuously challenged to reduce motorized joints’ size and weight while improving accuracy and response. This recording will discuss how direct drive motors coupled to high ratio precision gearing are an excellent choice to meet these challenges.
Speed Reducers & Proper Shaft Alignment for Motion Control Applications
The selection of a proper coupling for a motion-control application requires consideration of numerous performance factors that must be taken into consideration for the coupling to work properly. These factors include including torque levels, the type and amount of shaft misalignment, inertia, torsional stiffness, rotational speed, space requirements, and others.

TRENDS: 2021 & Beyond
We wanted to share an article, recently posted from RIA, Robotics Industries Association. It provides an excellent overview of 2021 and beyond for robotics and automation in various industry sectors, and how the pandemic helped to put robotics and automation in the forefront.
Torque Density Impacts Robot Speed
Humans know intuitively or from experience that if we put weights on our wrists or elbows, it becomes more difficult to move our arms. If we apply the same force we used without any weights, our arm will move more slowly.
It’s no surprise, then, that we see the same result in robots: as joints get heavier, the arm moves more slowly when the same force (or torque) is applied. Conversely, removing weight from the wrist or elbow actuator using a lighter weight transmission/gear drive results in higher speeds for the same applied torque.
What does a 10-15% increase in robot speed imply for robot owners?
Torque Density and Robot Reach
As we mentioned in the last post, we will be looking at how torque density influences different robot parameters, including reach, speed, and lifetime. Each of these in turn has a direct and important impact on the economic value of a robot to the end-user.
