Inline Coaxial Epicycloidal Reducers

The Nidec® VRL series has dimensions that allow the Gearbox to be a direct replacement for some other common competitor models. The machining quality of the helical planetary gears includes a gearbox that is very quiet and more efficient than competitive products. These planetary gearboxes are the perfect solution for servo drive applications such as injection molding machines, picking automation, and linear devices.

 

A great alternative for OEMs who need a high performance gearbox with a flexible mounting design and ease of mounting the Gearbox on their machinery. Positional accuracy and torque handling capabilities are ideal for custom-built packaging machinery, medical equipment, and cell automation. The VRB series planetary gearbox and its standard mounting flange are a dimensional replacement for some common competitive models.

The VRB provides a reaction rating of 3 Arc/min. as their standard, which means this series provides solid performance at an exceptional value.

This planetary series has exceptional load handling capabilities and is ideal for higher speed, continuous duty applications. Tapered roller bearings at the Gearbox output allow the VRS gearbox to handle larger thrust and radial loads. This internal design provides extremely smooth operation and a quiet gearbox even under high static forces. The VRS series is used in applications such as higher speed packaging and converting equipment, printing machinery and any servo application that requires very low reaction in a demanding environment.

Standard reaction is 3 arcs/min (one stage and two stage), ideal for higher levels of positional.

The VRT series sets the new standard for applications requiring extremely high torque ratings and rigidity. The compact design and hub-type output are ideal for equipment requiring high-speed, high-precision indexing motion. The torsional rigidity and low backlash of the planetary gear provide outstanding positioning accuracy.

With a recoil rating of less than 3 Arc/min. and exceptional torque handling capabilities, the VRT offers a robust, high performance planetary solution for OEM customers. The VRT Gearbox is suitable for larger applications of indexing and marking tables commonly found in packaging and filling equipment and assembly automation systems.

The VRSF uses a lightweight aluminum frame, helical cut gears, and a bearing stretch that provides the best level of precision and torque load capacity in its competitive class. The noise level generated by the VRSF is greatly reduced compared to competitive models based on spur gears.

The series is available in four frame sizes (B, C, D, E).

The VRSF can be selected with one of three levels of recoil: standard recoil at 15 arc/min, reduced recoil at 5 arc/min, and precision recoil at 3 arc/min.

Motion control applications in pharmaceutical, personal care, and food and beverage production environments require materials of construction and sealants that provide a higher degree of protection. To enhance our high precision product offering for customers in these industries, Nidec® now offers an a la carte washdown and food grade option for our inline and right angle planetary Gearbox.

These options provide maximum flexibility without sacrificing precision or performance. Different combinations of flush and feed level features include a stainless steel output shaft, SUS Ballscrews and bolts, sealed bearings, and an epoxy adhesive as a sealant. A package of food grade features includes a food grade white epoxy coating on the housing. Other custom coatings (ie Nickel Plated, Steel-it™, etc.) are available upon customer request.

These VRL and VRB inline frame sizes and ratios can be quickly assembled with any combination of the wash-on-demand or food-grade options.
