Optimal Engineering Systems, Inc. (OES) has added four high-resolution, low-profile goniometers to their expanding catalog of high precision positioning stages. This newly released, AK120-45 Goniometer Series features precision ground worm gears with a 296:1 ratio and pre-loaded cross roller guides, and +/- 45 degrees of travel with 10 kg of load. The very high resolution of 0.0006 degrees (2.16 Arcsec.) is realized when using the standard Two-Phase Stepper Motor driven by a 10 micro-steps per step micro-stepping driver or with the servomotor options and Quadrature Optical Encoders.
The Franz Morat Group is exhibiting at SPS in Nuremberg in Hall 1, Booth 350. This year, the company is showcasing a wide range of precision gearing components and innovative drive technology solutions.
Regal Rexnord Corporation has added two new models to its portfolio of Boston Gear Gen2 SS700 Series stainless steel worm gearboxes. The new sizes bring the full product lineup to seven. A larger output shaft bore expands the number of applications each model of gearbox can support, providing flexibility and versatility for customers in a range of industries, including food, beverage and pharmaceuticals.
Ketterer i-Wheel 3213 wheel hub drives have been specially developed for use in Automated Guided Vehicles (AGV). They are designed as direct drives that are completely integrated in the hub and therefore need neither an additional gearbox nor an extra wheel.
Boston Gear recently introduced the next generation of its 700 Series Worm Gear Speed Reducer. The SS700 Gen2 stainless steel speed reducer is an evolution of its first-generation series that has served the food and beverage industry for over 10 years.
The cylindrical die rolling process can produce helical, axial, and annular forms on shaft-like parts at high rates of speed with precision tolerances.
Why use the rolling process to produce high accuracy lead screws, actuator screws, and other power transmission components rather than traditional cutting processes such as turning, grinding, milling, whirling, or hobbing? Rolling processes and cutting processes both produce a precise form on the workpiece. But if the form geometry, tolerances, and material selection allow, rolling is the process to beat. Speed, surface finish, fatigue strength, precision, dimensional stability, and material savings are some of the primary advantages realized when the rolling process is applied.
Designed for larger cameras, tracking devices, telescopes, optics, and other devices, four new, high resolution, three axis gimbal mounts have been released by OES (Optimal Engineering Systems, Inc.). This new series of Three Axis Gimbal Mounts are 588 mm wide by 463 mm high, and handle loads up to 10 kg. The AU400-AER (Azimuth, Elevation, and Roll) Series of Three Axis Gimbal Mounts feature high precision 180:1 worm gear driven “V” groove rotary stages. Each axis is capable of 360 degrees of continuous rotation in clockwise and counterclockwise directions. The position is held economically when the motor current is removed as worm gears cannot be back driven. The Roll Stage has a precision pattern of threaded holes for mounting tooling, cameras, lasers, etc., and a through hole for cables and optics. Devices up to 395 mm wide can be mounted on the rotary stage.
Optimal Engineering Systems, Inc. (OES) has added four goniometers to their expanding catalog of high precision positioning stages. The new, AK160-30 Goniometer Series feature precision ground worm gears with a 400:1 ratio and pre-loaded cross roller guides offer +/- 30 degrees of travel with 30 kg of load.
If torque conversion with high gear ratio, compact installation space and 90-degree axis-crossing angle is needed, often worm gears are used. Due to their high power density and sliding speeds within the tooth contact, frictional heat and thermal stresses are higher compared to helical, bevel and hypoid gears, and thus the thermal load capacity of worm gears is lower.
In the selection of lubricating greases for plastic worm gears, the user needs to know the influence of each grease constituent on the tribological performance in order to choose the appropriate lubricant. In this work, the effect of NLGI class, viscosity, base oil and thickener type are investigated separately regarding the efficiency and temperature close to the tribocontact. With the help of this contribution the user understands the effect of each parameter and learns about the potentially reachable efficiency and temperature ranges.
