MRIG Series Spur Gearboxes - Mclennan Servo Supplies Ltd.

Multi-role instrument gearheadMRIG seriesThe MRIG series gearheads have been designed for use inheavy duty instrumentation or light duty industrial driveapplication. The combination of a hardened metal spur geartrain coupled with a precision die-cast housing results in arobust design with a high torque transmission capability.MRIG has been designed to fit a wide range of motorsincluding:• high torque reversible ac synchronous types• permanent magnet & hybrid stepper motors• dc servo motors with optional brake, encoder ortachogenerator.• brushless dc motorsRobust construction with built motor mounting flexibilityA key feature of the MRIG design is it’s ability to accept standardmotor shafts without the need for modification. This enables a widerange of motors including NEMA size 23 stepper motors to be fitteddirectly to the unit while dc and brushless servo motors are fittedusing a simple mounting adapter. Gear strength is a key feature ofthe MRIG design. The use of steel gears and pinions with carefullyselected hardness grades ensures a high torque transmissioncapacity and long life while a robust precision diecast metalhousing offers excellent protection in industrial installations.In it’s standard form MRIG gearheads are provided with heavy dutysleeve bearing on the output shaft, ball bearings being available tospecial orderStandard Gear ratiosFast-track delivery of the following ratios is ensured by the maintenance of comprehensive stock levels.Geared motor combinations based on the MRIG gearhead series are assembled in our fast responseassembly cell to provide our customers with fast delivery to meet their changing demands.OrderCodeGearratioNumber ofstagesDirection ofrotation**EfficiencyMaximumcontinuousoutput torqueMRIG02 * 5:1 3 opposite 72% 1.5 NmMRIG06 * 25:2 3 opposite 72% 2.5 NmMRIG11 * 25:1 4 same 65% 4.0 NmMRIG17 * 50:1 4 same 65% 4.0 NmMRIG22 * 100:1 5 opposite 58% 4.0 NmMRIG23 * 125:1 5 opposite 58% 5.0 NmMRIG27 * 250:1 6 same 52% 6.0 NmMRIG34 * 500:1 6 same 52% 7.0 NmNote: * Add ‘S’ for standard Sleeve Bearings on Output shaft‘ B’ for ball bearings* * Direction of rotation of output compared to inputMclennan Servo Supplies Ltd.
