Beier Variator

Adjustable Speed,Viscous Traction Drive

Specifications

Product Description

The Beier Variator is an adjustable speed traction drive whose design and method of speed variation is truly unique. Power is transmitted through the viscous friction of an oil film that separates multiple thin metal discs. Variations in the depth of engagement between the driver and driven discs provide the means of adjusting speed. A mechanical handwheel is used to provide incremental adjustment over the drive speed range. A threaded adjusting screw locks the set speed, eliminating "speed jumps" and maintaining the set speed.

The ultra-compact combination of a Beier Variator and a Cyclo Reducer results in a Beier Cyclo Variator that provides not only an adjustable speed range, but extremely low output speeds as well. Both units have proven performance in severe working environments, and in high-reliability applications that cannot tolerate breakdowns. Environmental protection is standard on all units, with completely sealed, oil immersed internal components, preventing moisture, dirt and dust from entering and causing damage or failure.

Features & Benefits

• High efficiencies of up to 90%, even at high speeds
• Minimal maintenance, with no belts or disks to wear and fail
• Long life and low maintenance cost due to minimal metallic contact and no wear, grooving or fretting corrosion
• Infinitely adjustable speeds within 3.3:1, 4:1 and 10:1 speed ranges, with settings that remain stable over long periods of time.
• Vibration-free operation, due to completely symmetrical rotational parts and low moment of inertia.
• Easy installation and handling, and space-saving compact design with exceptionally high torque ratings.
• Wide range of options includes special motors, enclosures and controls
• Ratings are based on 24 hour/day duty and product selection is pre-calculated with a 1.25 service factor
