Thomson Industries, Inc. (Wood Dale, IL) has introduced a line of precision ball splines that enable robust delivery of rotary and linear motion on a single shaft. These new components give designers more flexibility to compress an assembly, extend a stroke, distribute a load or otherwise meet modern automation demands.
Ball splines exploit the low-friction torque transmission capabilities of rolling balls and augment that by adding one or more axial grooves, also known as splines, along the assembly shaft. That opens a low-friction path through which the balls move to facilitate low-friction axial displacement, while also transmitting torque.
The new line of Thomson high-precision ball splines is ideal for high-speed operation in compact spaces such as laboratory automation or semiconductor pick-and-place assembly. They can automate functions that a human might otherwise perform, like opening the cover of a sample jar and pouring it in a test tube. And they are especially cost-effective in industrial robotic applications that require high-speed, precise integration of rotary and linear motion without the wide freedom of movement of robots.
Thomson precision ball splines are available immediately in lengths up to 300 mm; diameters between 6 and 30 mm standard. Larger diameters of 40 and 50 mm are available upon request.
