Nidec® Planetary Gearboxes VR series show excellent versatility combined with very high quality; certified by a manufacturing process that includes constant checks of each component, and final tests of the complete product for angular backlash, noise, back-drive resistance and slip resistance. Through the use of software optimized helical gearing, a superior tooth hardening process, and extremely close machining tolerances, we can offer an optimum power density which will satisfy the highest dynamic and precision requirements. Nidec® gearboxes are interchangeable with most of the gearboxes on the market.
quiet and more efficient gearbox than competitive products. These planetary gearheads are the perfect solution for servomotor applications such as gantries, injection-molding machines, pick and
place automation, and linear slides.Standard backlash is 5 arc/min (one stage and two stage), ideal for the most accurate applications.
The positional accuracy and torque handling capabilities are an ideal fit for packaging machinery, medical equipment, and custom assembly cell automation.
The VRB Series planetary gearbox and its standard mounting flange are a dimensional replacement for a few common competitive models.
The VRB provides a backlash rating of 3 arc/min. as its standard,
which means this series provides solid performance at an exceptional value.
This planetary series has exceptional load handling capabilities, and it is an ideal selection for higher speed and continuous duty applications. The tapered roller bearings at the output of the reducer allow the VRS gearbox to handle larger radial and thrust loads. This internal design provides an extremely smooth running and quiet gearbox even with challenging static forces. The VRS series is commonly utilized in applications such as higher speed packaging and converting equipment, printing machinery and any servo application requiring very low backlash in a more demanding environment.Standard backlash is 3 arc/min (one stage and two stage), ideal for higher levels of positional.
The compact design and hub-style output is ideal for equipment requiring high speed, high precision indexing movement.
The torsional stiffness and the low backlash of the planetary gearing combine to provide outstanding positioning accuracy.With a backlash rating less than 3 arc/min. and exceptional torque handling capabilities, the VRT offers a high performance robust planetary solution for OEM customers.
The VRT reducer is often used for larger indexing applications and dial tables commonly found in packaging and filling equipment and assembly automation systems.
The VRSF utilizes a lightweight aluminum frame, helical cut gears, and a bearing span that provides the best level of precision and torque carrying capacity in its competitive class. The noise level generated by the VRSF is greatly reduced in comparison to any other competitor’s economy class series that relies on spur gearing.
The series is available in four frame sizes (B, C, D, E).
The VRSF can be selected with one of three backlash levels – Standard backlash at 15 arc/min, Reduced backlash at 5 arc/min, and Precision backlash at 3 arc/min.
- Low running noise; carburized helical gears contribute to reduce vibration and noise.
- High torque; uncaged needle roller bearing provide excellent torque density.
- Adapter-bushing connection; can be attached to any motor all over the world.
- High efficiency
- Efficiency rate ≥ 95%
- Maintenance-free; no need to replace the grease for the life of the unit.
- Can be attached in any mounting position.
Motion control applications in the Food and Beverage, Personal Care, and Pharmaceutical production environments often require materials of construction and sealants that provide higher level s of protection. To improve our high precision product offering to customers in these industries, Nidec® is now offering a washdown and food grade duty al a carte options for our inline and right-angle planetary reducers. These options provide ultimate flexibility without sacrificing on precision and performance.
Different washdown and food grade feature packs include a stainless-steel output shaft, SUS screws and bolts, sealed bearings, and an epoxy adhesive as the sealant. A food grade feature pack includes a white Food-Grade Epoxy coating on the housing. Other custom coatings (i.e. Nickel plating, Steel-It™, etc.) can be made available upon request.
A special Food-Grade grease is an option that can be specified by the customer where required, but we suggest that you contact Nidec® to help with proper sizing and selection.
These VRL and VRB inline frame sizes and ratios can be quickly assembled with any combination of the a la carte washdown or food grade duty options.
