Maxon Planetary Gearbox gp 6 a ∅6 Mm, 0.002–0.03 Nm. All Models Are Available for Inquiry With Advantageous Supply.
I. Product Overview
GP 6 A is a classic standard micro planetary gearhead from Swiss company maxon, precisely manufactured at the German original factory. It has an outer diameter of only 6mm. The "A" represents the general-purpose steel standard version, specially designed to be compatible with the Φ6mm micro coreless motors Maxon in the DCX 6 and ECX 6 series. The torque ranges from 0.002 to 0.03 Nm, with 1 to 5 levels of modular deceleration. It is compact in size, features coaxial transmission, and can operate in a wide temperature range from low to high. It is the mainstream economical transmission solution for minimally invasive medical procedures, precision optics, and micro portable devices. Difference: GP is the traditional standard micro gearbox; GPX is the new generation of lightweight high-speed series, and GP6A offers better cost-performance and a complete range of in-stock specifications.
II. Basic Structure and Configuration
Transmission form: Straight-tooth planetary structure, with the input/output running coaxially in the same direction
Output component: Stainless steel output shaft, standard equipped with ball bearings (sliding bearings are optional)
Housing gear: Steel internal gear ring + steel planetary gears, a general-purpose wear-resistant configuration
Stage specifications: Free combination of 1/2/3/4/5 stages, covering the entire reduction ratio range from 3.9:1 to 854:1
Operating temperature range: -40℃ to +100℃, suitable for both high and low temperature equipment
III. Core Technical Parameters (Original Factory Standards)
1. Comparison Table of Graded Torque and Reduction Ratio
Table
| Reduction Stages | Standard Reduction Ratio | Continuous Rated Torque (N・m) | Short-term Peak Torque (N・m) |
|---|---|---|---|
| 1 stage | 3.9:1 | 0.002 | 0.005 |
| 2 stage | 15:1 | 0.005 | 0.010 |
| Level 3 | 57:1 | 0.010 | 0.020 |
| Level 4 | 221:1 | 0.030 | 0.060 |
| Level 5 | 854:1 | 0.030 | 0.060 |
2. Rotation Speed, Efficiency, and Backlash
Continuous input rotation speed: 40000 rpm, suitable for high-speed micro brushless motors
Transmission efficiency: 88% for single-stage, and the efficiency slightly decreases as the number of stages increases
Average no-load backlash: ≤1.8° for single-stage, ≤2.5° for multi-stage, with stable positioning accuracy
Total weight of the machine: 1~4g, lightweight without additional load
3. Output Load Capacity (5mm outside the flange)
Dynamic axial load: 5 N
Radial load: 5~8 N (increasing with the number of stages)
Allowable press-fitting pressure: 10 N
Radial clearance ≤0.12 mm, axial clearance ≤0.10 mm
4. Core Advantages of the Product
Ultra-micro body: Extremely small outer diameter of Φ6mm, suitable for narrow installation spaces such as endoscopes and micro probes;
Wide torque coverage: Torque from 0.002 to 0.03 Nm for single-stage to five-stage, fully covering small-load precise fine-tuning;
High general adaptability: Directly pluggable and assemblable with all 6mm motors of maxon, no adapter seat required, high coaxiality;
Stable operation in a wide temperature range: Stable output from a low temperature of -40°C to a high temperature of 100°C, suitable for airborne and in vitro diagnostic equipment;
Low noise and low vibration: Precise gear grinding process, uniform gear surface meshing, silent operation for optical and medical equipment;
High-cost-performance standard model: Steel gears are durable under normal working conditions, standard reduction ratios are in stock, and the delivery cycle is short.
V. Typical Application Scenarios
Steering drive for minimally invasive medical device endoscopes, biopsy probes, adjustment mechanisms for micro infusion pumps, and handheld dental micro drives;
Focusing modules for microscopic lenses of precision optical instruments, portable fundus cameras, fine adjustment of laser light paths, and micro spectrometers;
Micro intelligent devices such as micro pipeline inspection robots, transmissions for wearable devices, and small detection probes;
Aviation and laboratory equipment such as satellite micro solenoid valves, airborne micro actuators, and laboratory micro titration drive units.
