Image - Why precision metrology is critical for electric vehicle gearing
Why precision metrology is critical for electric vehicle gearing
As the shift from internal combustion engines to electric motors in vehicles continues, the number of drivetrain components will dramatically lessen too. The remaining components will be even more critical to a vehicle's operation and longevity. One such area is the gear components necessary to convert the high-force torque from electric motors to the RPMs at the wheel.

Why you should use a Smalley Spirolox® retaining ring vs. a stamped snap ring
While there are a variety of retaining rings available in the industry, engineers specify Spirolox retaining rings because of their unique configuration, reliability, and convenience. This blog compares a traditional snap ring to a Smalley Spirolox retaining ring, as there are notable differences between them, including Design Flexibility, Appearance, Installation, and Removal.

Customizable frameless DC torque motors handle a wide range of applications
Kollmorgen's compact and adaptable Frameless DC Torque Motors are ideal for positioning or speed control systems that require high stall torque, high torque at low speed, or optimum torque at high speed. Applications include: Forward-Looking Infrared Radar (FLIR), missile fin actuators, medical pumps, gimbal systems, and other critical applications requiring high reliability. These Frameless DC Torque Motors can be easily integrated into custom-designed housings, including DC tachometers, resolvers, encoders, and customized shafts.

Image - What's a strain wave harmonic gearing torque sensor?
What's a strain wave harmonic gearing torque sensor?
Strain wave harmonic gearing sensors from FUTEK are an alternative to six-degrees-of-freedom (DOF) sensors used in applications such as robotic arms that are used in surgery. For example, during some laparoscopic surgery procedures, surgeons must hold the position of the end effector (the instrument inside the abdominal cavity) while the robot arm is moving. This maneuver is difficult to perform with 6-DOF sensors only, because it requires torque measurement on each joint. Strain wave harmonic gearing sensors can handle it, and they are less expensive to implement because torque measurement can be obtained for selected joints only if necessary.

Aerospace fastener hole drilling and countersinking all in one step
Kennametal has introduced the HiPACS drilling and countersinking system for aerospace fastener holes. Designed to drill and chamfer holes in one operation, the high-precision tool meets the aerospace industry's stringent accuracy requirements while delivering increased tool life in machining composite, titanium, and aluminum aircraft skins. With an industry-standard interface, HiPACS can be utilized on any CNC machine. Three components eliminate the need for custom tooling: a reducer sleeve with a built-in high-precision pocket seat, a PCD countersinking insert, and two series of solid carbide drills.

New bearings reduce wear in heavy-duty applications
igus has introduced a new bearing with an improved iglide material, called TX2, that offers self-lubricating and maintenance-free properties for heavy-duty applications. TX2 increases wear resistance by a factor of 3.5 in load ranges with more than 100-MPa surface pressure. The material is ideal for components in machines that serve construction and agriculture, which can require more than 50 liters of lubricant annually. The material is also very resistant to temperature, chemicals, moisture, corrosion, and seawater, which opens up the applications base for its use substantially.

Round vs. square rails -- which are better for you?
Thomson invented the world's first anti-friction linear ball bushing bearings in 1946. For many years, these round-rail linear guides satisfied every linear motion control requirement. However, as machines required closer tolerances, the round rail didn't always fit the bill. Learn the pros and cons of each design type.

Self-clinching fasteners for composites, plastics, and other rigid materials
The PEM® VariMount® fastening system from PennEngineering® enables the use of PEM self-clinching fasteners for attachment applications in composites, plastics, metal, and any rigid material or panel. The system integrates a self-clinching nut, stud, or standoff pre-installed permanently into a steel or stainless steel base plate. The base plate with multiple radial holes effectively becomes a mounting platform that can be bonded or mechanically attached to virtually any rigid material. Once mounted, the pre-installed PEM self-clinching fastener ultimately is positioned where designed to accept mating hardware. So many possibilities.
