In-line Coaxial Planetary Gearboxes

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 very quiet gearbox that is more efficient than competitive products. These planetary gearboxes are the perfect solution for servo motor applications such as injection molding machines, picking automation, and linear devices.

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

A great alternative for OEMs who need a high-performance gearbox with a flexible mounting design and ease of mounting the reducer on their machinery. The 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 Arc/min. as standard, meaning this series delivers solid performance at exceptional value.

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

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

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 gear provide outstanding positioning accuracy.

With a backlash 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 indexing applications and indexing tables commonly found in packaging and filling equipment and assembly automation systems.

The VRSF utilizes a lightweight aluminum frame, helical cutting gears, and a bearing section 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 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 food and beverage, personal care, and pharmaceutical production environments require construction materials and sealants that provide a higher degree of protection. To enhance our offering of high-precision products for customers in these industries,^Nidec®nowoffers an à la carte washdown and food-grade option for our inline and right-angle planetary gearboxes. These options provide maximum flexibility without sacrificing precision 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 customer request.

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