Redex USA objectives remain the same: Providing quality unique gearboxes and solutions for use on industrial machinery.

KRP+ the ‘KIT’ concept includes output flange mounting and integral output pinion which are dedicated to rack & pinion applications.

KRP+ planetary reducers are the SingleDRIVE components in a family of reducers dedicated to Rack & Pinion and Rotary Table drive applications. They can be used alone as a single drive or combined with a second unit to create a ZERO-BACKLASH linear or rotary Axis.

As A SingleDRIVE, the KRP+ features an integral output pinion and planetary gear train that have been optimized for minimum backlash (1 – 3 arc minutes) and maximum STIFFNESS ON RACK.

DualDRIVE kit combines two KRP+ reducers in a patented, mechanically preloaded ZERO-BACKLASH system. The two units are torsionally preloaded against the rack in this closed loop mechanical system. Only one motor is required to drive the axis.

Two KRP+ reducers can also be combined together in an electrically preloaded TwinDRIVE kit. Backlash is eliminated using two motors, one to drive the axis and one to preload the axis.

DRP+ DualDRIVE & TwinDRIVE includes monoblock housing for universal mounting. DRP+ planetary gearboxes are the dedicated solution to ZERO-BACKLASH rack & pinion and rotary table drive applications.

They consist of two top quality planetary reducers mounted in parallel inside of a super rigid universal housing. Two integral output pinions engage the rack to allow preloading of the system and maximize the Stiffness on Rack. When choosing the mechanical preload solution, the DRP+ becomes a DualDRIVE unit, which achieves ZERO-BACKLASH by torsionally winding one pinion against the other through the rack. Only one motor is required to drive the axis simplifying motor control.

DRP+ becomes a TwinDRIVE when the Electrical preload solution is applied to cancel the backlash. In this case backlash is eliminated by using two motors; one to drive the axis and one to preload the axis.

KRPX is a Side Mounted high performance planetary Servo-Reducer, dedicated to Rack & Pinion applications.

The unique KRPX housing is designed to act as a RIGID MACHINE FRAME EXTENSION. The accessible side mounting offers a cost effective, easy to implement, high performance solution for both linear and rotary axis drives.

Two units are combined together with electrical preload (TwinDRIVE) to create an extremely stiff ZERO-BACKLASH axis. The KRPX housing design has been optimized by finite element analysis to avoid deflection during acceleration and heavy loads. Furthermore, the output pinions are machined directly into the output shafts and supported by extra-large, preloaded tapered roller bearings to provide the best balance between transmittable torque and stiffness on the rack.

Andantex is pleased to introduce a smaller size, KRP 0, rack and pinion dedicated reducer. This compact, cost effective solution includes integral module 3 helical output pinions. There are two standard output pinions 14 teeth or 18 teeth along with three standard ratios 5, 7 and 10 providing machine designers a library of standard solutions. Units are available In-Line or Right- Angle. Furthermore ZERO-BACKLASH DualDRIVE (one motor) or TwinDRIVE (two motors) arrangements are available.

The inherent stiffness and robust life of the KRP range make these units an excellent choice for routers and cutting (laser, waterjet, etc.) machines. The ZERO-BACKLASH options allow the elimination of linear scales while still providing required accuracy and precision. Finally, the inclusion of the pinion makes these products extremely cost effective for linear or rotary axis drives.

This range of planetary reducers is designed for use with servo-motors in all kinds of industrial applications with a focus on cutting machines (laser, water-jet, plasma, stone, etc.) and routers. The compact dimensions allowed by the planetary construction and the availability of 4 backlash precision classes insure cost effective solutions that meet the necessary application precision.

The in-line configuration can be mounted in horizontal, vertical or any position. One two or three stages allow for ratios from 3:1 to 1000:1. Servo-motors are easily adapted to the input and output options include integrated pinion, output shaft (plain, keyed or splined), or hollow bore.

The two sizes extend the range of Andantex SRP planetary reducers so that all axis requirements on a machine can be provided by one supplier.

The Preloaded Double Pinions, PDP, from Andantex (WMH Herion) is designed to provide a cost effective method of eliminating backlash between the rack and pinion in high precision linear motion applications. The PDP is made of two ground WMH pinions, each ½ the width of the rack, connected together through a patented coupling preload system that cancels the backlash between rack and pinion providing a competitive alternative to ball screw drive systems.

The preload torque of the PDP is easily adjusted and the units are equipped with an ISO 9409-1 flange for adapting to speed reducers. The PDP can be combined with precision reducers to provide system backlash < 1 arc-minute thereby eliminating the need for two electrically preloaded reducers (with 2 servo motors) in certain applications.

The PDP is offered with straight (spur) or helical gears in modules from 2 to 5 standard (larger modules on request) and accepts speeds up to 1200 RPM. Torque capacity ranges from 55 – 1900 NM depending on the size and preload torque setting. Andantex can offer complete solutions in including reducer, PDP, rack and automatic rack lubrication systems.

Specialized lubrication pumps with accessories and specialty greases for automatic re-lubrication of racks and pinions, open gearing, linear guideways, ball screws, and chain drives. Andantex USA offers two sizes of the Flexxpump with grease capacities of 1500 cc or 400 cc. The Flexxpump units can also be used for lubrication with oil with refillable reservoirs from 500 to 2,000 cc. The positive displacement piston pump with built in check valves can deliver up to 70 bar (1000 psi) of pressure to pump greases up to NLGI 2. Flexxpumps can be supplied with on board programing or set up to be controlled by the machines PLC. Our greases were developed specifically for optimum lubrication of gearing, linear slides, ball screws, and food industry environments. The greases provide the correct mix of viscosity, adhesive additives, and corrosion resistance for the specific component being lubricated. The open cell Polyurethane (PU) foam applicators allow the lubricant to be applied or absorbed to insure the correct film thickness for optimum lubrication. Flexxpump is a compact, cost effective system that helps take the guess work out of lubricating components.

The MSR 2-Speed VTL turntable is a new technology that combines two right angle, 2-speed gearboxes to perform high power turning and precise C-Axis motion for milling. The MSR output pinions mesh with the turntable ring gear. In the turning mode both motor-gearboxes work together sharing the load (50%-50%) and keeping the motor size ½ of a conventional main drive motor. During the positioning and milling (C-Axis) mode, one gearbox is preloaded against the other to eliminate backlash and insure accurate positioning. Furthermore, the gear ratio shifting covers the full range of speed required with high speed for turning and low-speed high torque for milling.

Full load is provided during turning and backlash is cancelled during milling.

The MSR is a compact system that dramatically simplifies VTL turntable kinematics and insures high performance with respect to speed range, torque and accuracy.

The Heynau H-Drive is one of the most well known mechanical variable speed drives. The simple construction of this all steel drive with only a few components, meets the highest requirements for quiet operation, precise speed holding, high efficiency and durability.

The drives utilize a set of cones, which transmit power via an encapsulating steel ring. By adjusting these cones in relation to the steel ring, a speed adjustment range of 6:1 or 9:1 can be achieved ( 3:1 reduction and 1:2 or 1:3 increase). This speed range can be realized while the machine is at rest or in motion.

These drives can be arranged with input and output reducers to achieve hundreds of speed and power ratings. Motors can be attached to the input for complete drive packages.

In a compact package, these servo reducers feature minimum backlash, low input inertia, high torsional stiffness and precise repeatability.

Backlash correction insures that the original backlash value of the reducer can be maintained for the life of the unit.

An input flange can be provided for direct mount to any servo motor. Each reducer is performance certified to the customer’s specifications prior to shipment, and is delivered with a data sheet documenting the unit’s performance.
