Dedicated to racks & pinions drive applications, the KRP+ design is based either on the use of one single unit or on the association of two top quality planetary reducers, mounted in parallel on the machine main frame.
When used as a SingleDRIVE, the KRP+ gives the benefit of an ultra high stiffness feed gearbox, dedicated to high performances rack & pinions drive systems.
When choosing the mechanical preload solution, the KRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack.
Immediate benefits are to need only one motor, and to dramatically simplify the motor control.
When choosing the Electrical preload solution, the KRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.

Spur Gears
A new range of 20° PA. spur gears all manufactured in medium carbon steel, provide selection from 1 Mod. through to 6 Mod. pitch with gears from 12 teeth to 120 teeth. Gears have face width equal to ten times Mod. number to provide sensible power transmission capability. To supplement the steel gears is a select range of cast iron wheels covering pitch range 2 Mod. to 5 Mod.with 30 to 60 tooth size.
Straight Racks
Available in standard lengths of 05, 1.0 and 2.0 metres is a range of 20° PA straight cut racks with pitch range 1 Mod. to 6 Mod. These are designed to combine with the standard spur gears to provide low cost conversion of rotary to linear movement. |

Nexen offers an advanced new technology that revolutionizes linear movement. The Roller Pinion System (RPS) provides zero backlash, very high positional accuracy, unlimited length, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up
new design possibilities and provides the capability to achieve much higher levels of performance in machine designs.
The RPS's unique design eliminates many of the limitations of current linear drive systems like:
Ball screws: Limited by critical speed, maximum speed, cumulative error, vibration, thermal expansion, supplemental cooling, noise, low efficiency, maintenance, and life.
Traditional Box and pinion: Limited by low accuracy and speed, backlash, tooth fatigue, noise, high cost of dual and split pinion systems, high maintenance, and short life.
Professional belt Drives: Limited by low accuracy, backlash, low load capacity, short lengths, belt stretch, and low rigidity.
Linear motors: Limited by low load capacity, high cost, strong magnetic fields, and liquid cooling.

Dedicated to racks & pinions drive applications, the DRP+ design is based on the association of two top quality planetary reducers, mounted in parallel on an extra high stiffness universal frame.
When choosing the mechanical preload solution, the DRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack.
Immediate benefits are to need only one motor, and to dramatically simplify the motor control.
When choosing the Electrical preload solution, the DRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.

DIRECT ACTING INDUSTRIAL PRESSES
Rack-and-pinion presses with round ram
APZ series
mäder rack-and-pinion presses transmit their pressing
force constantly over the entire length of the stroke.
Direct power transmission via the hand lever permits
extreme precision in the pressing operation.
The improved transmission ratio enables a higher compression
force to be achieved for the same force
applied.
The following quality features are characteristic of all
mäder rack-and-pinion presses:
- anti-twist ram
- infinitely adjustable stroke length:
Standard: via setting screw
MICRO: via manufacturer of micrometer screw
- Height adjustment of the press head using
a threaded spindle
- 360° infinitely adjustable hand lever
- adjustable return stroke power
Rack-and-pinion presses are therefore ideal for:
- pressing-in longer components and for
- jointing operations over long strokes |
