Mclennan enhances P5 gearheads
Mclennan's P5 series of precision instrument gearheads has undergone some design enhancements resulting in improved delivery times and increased application durability.
The P5's final output gear arrangement maintains an identical tooth form and diameter regardless of the reduction ratio.
This allows final gear and shaft assemblies to be held in stock as 'blanks' that are machined to suit standard output shaft requirements and provide the means for a fast turnaround for customised shafts.
A further change is that the housing material is now produced in Zytel FR7025, a flame retardant plastic, for improved compliance in hazardous environments.
Through Mclennan's distribution network with motor manufacturers, including Portescap, Premotec and Tamagawa, a wide range of permanent magnet stepper motors, ac synchronous and instrument dc servo motors are available to complement the P5.
The standard P5 range covers ratios from 10:1 to 15000:1 in 18 models with an output torque rating of 0.8Nm.
The flexibility and modularity built into the range allows customised versions to include strengthened bearings for increased loading and higher speeds, improved lubrication for extended life, alternative gear materials for noise free operation and clutch/freewheels for torque limiting and anti-backdriving.
The adaptability of the P5 is demonstrated with a standard positional servo drive version comprising of an ironless rotor servo motor drive and a dual output shaft with a potentiometer fitted for up to 360deg of angular position feedback.
Mclenna say that the P5 series has also proved as a power transmission component as part of complete mechatronic assemblies for specialist positioning applications across all areas of industry and research.
