In-line Coaxial Epicycloidal Reducers

The Nidec® VRL series has dimensions that allow the gearbox to be a direct replacement for several common competitor models. The high-quality machining of the helical planetary gears results in a very quiet and more efficient gearbox than competing products. These planetary gearboxes are the perfect solution for servomotor applications such as injection molding machines, picking automation, and linear equipment.

The standard reaction is 5 arcs/min (one stage and two stages), ideal for the most precise applications.

A great alternative for OEMs needing a high-performance gearbox with a flexible mounting design and easy installation of the reducer on their machinery. Positional accuracy and torque handling capabilities are ideal 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 some common competitive models. The VRB provides a reaction rating of 3 arcs/min as standard, meaning this series delivers solid performance at an exceptional value.

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

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

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-precision, high-speed indexing motion. The torsional rigidity and low backlash of the planetary gearing provide outstanding positioning accuracy.

With a backlash rating of less than 3 arcs/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 indexing applications and marking tables commonly found in packaging and filling equipment and assembly automation systems.

The VRSF utilizes a lightweight aluminum frame, helical gears, and a bearing section that provides the best level of accuracy and torsional load capacity in its competitive class. The noise level generated by the VRSF is significantly reduced compared to competing 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 recoil levels: standard recoil at 15 arcs/min, reduced recoil at 5 arcs/min, and precision recoil at 3 arcs/min.

Motion control applications in the food and beverage, personal care, and pharmaceutical production environments require construction materials and sealants that provide a higher level of protection. To enhance our high-precision product offerings for customers in these industries, Nidec ^® We now offer a choice of washdown and food-grade options for our in-line and right-angle planetary gearboxes. These options provide maximum flexibility without sacrificing accuracy or performance. Different combinations of washdown and food-grade features include a stainless steel output shaft, SUS screws and bolts, sealed bearings, and an epoxy adhesive as a sealant. A food-grade feature package includes a white, food-grade epoxy coating on the housing. Other custom coatings (i.e., nickel plating, Steel-it™, etc.) are available upon request.

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