Product overview Take six – The product at a glance Due to their outstanding mechanical properties, planetary gearboxes are found in a wide spectrum of industrial applications. Güdel high-precision planetary gearboxes provide the ideal solution for demanding operations. Performance details and drawings are found on the technical datasheets. Precision – With regard to angular backlash, our extensive experience in the design and the manufacture of high-performance gearboxes gives us the ability to provide all products in four different precision grades: 1, 3, 5 and 12 arcmin Sizes – Our...

duty cycle duty cycle NRHP & NGHP NR type – For high flexibility SR type – For high torque PR type – For hyper torque For use in most applications that require torque, precision and high speed operation in continuous S1 and discontinuous S5 duty cycles. Without an increase in size, the SR range provides 33% more torque than the NR range and is used in discontinuous duty cycles of S5 and more. Without an increase in size, the PR range operates with 100% more torque than the NR and is used in discontinuous duty cycles of up to S5.

NGHP – An innovative system solution Planetary gearbox with integrated eccentric output flange which provides precise gear mesh adjustment for the rack and pinion drive train. The performance of a rack and pinion drive system is greatly influenced by how precisely the gear mesh between rack and pinion are set, as well as by the precision of the individual components. This gear mesh is typically set via the radial relationship of the pinion to the rack. To achieve low backlash, the pinion engages with the rack through a linear movement of the gearbox. While seemingly easy in theory, this...

Compact package with high stiffness The planetary gearbox NGHP is built on the proven technology of the Güdel NRHP Series planetary gearboxes. The addition of the unique adjustable flange mounting methodology provides both ease of adjustment and superior torsional stiffness and rigidity. All-new interface The all-new designed interface of the NGHP gearbox with the eccentric output flange guarantees optimal performance due to its form fit support. Furthermore, the new interface simplifies the customer structure and thus helps to reduce costs. Integrated output pinion CP The all-new designed...

Six types to cover a wide range of application requirements Our six types, NRH, NRHP, NGHP, NR, SR, and PR provide you with a broad performance spectrum. Input speeds range up to 6000RPM, and output torques up to 5600 Nm. The NRH, NRHP and NGHP types provide an excellent combination of performance characteristics: torque, speed, precision, low noise, and high duty cycle. The NRHP and NGHP are suitable when high stiffness and tilting rigidity is required. The NR type offers flexibility and modularity, with the largest range of sizes, stages, and ratios. The SR and PR ranges focus...

Make your decision – Range, speed & torque Use the technical summaries to make your preselection from the five main gearbox types. Base your gearbox selection on the most important requirements for your particular application: torque, gearbox size, duty cycle, angular backlash, ratio, and speed. Select NRH, NRHP and NGHP for high input speeds, or the NR type when modularity and a wide range of sizes, stages, and ratios is most important. Choose the SR or PR type if your application requires high or hyper torque. The following graphs are based on a ratio of 12 in a discontinuous S5 duty...

Great adaptability – Standard & optional inputs Due to our modular system, all common servo motors can be easily mounted on our planetary gearboxes. Optional inputs such as primary shaft can be provided on request. We have a standard flange solution for the most commonly used servo motors. Depending on the range of the gearbox, we offer a total of three standard input versions. Your selection of an input will depend on the geometric dimensions of the motor. Standard inputs Small motor Medium motor

Standard inputs Optional inputs For special applications, in which the motor cannot be directly mounted on the gearbox, it is possible to fit the gearbox with an optional input shaft. Example AL AL – Smooth primary shaft AC – Keyway primary shaft

Unlimited flexibility – Standard and optional outputs To meet your requirements, our planetary gearboxes offers six output options to cover the broadest possible range of applications. Three standard outputs are available in stock, with three additional outputs available upon request. Please don’t hesitate to contact us if your application requires a configuration not shown here. Smooth output shaft and flange The reference standard output with dimensions according to market standards. Keyway output shaft A keyway according to DIN 6885 can be added to the smooth shaft. Integrated output...

Optional outputs Customized output shaft Please contact us, if the standard output shafts do not meet your specification. Hollow keyway output On request we can provide you with a hollow keyway output. Please find the details on the technical information pages. Splined output shaft Splined output shafts are available on request. Please specify dimensions as well as type of spline (standard) and tolerances required.
