How HONPINE IP68 Harmonic Drive Motor Helps Underwater Robots Achieve High-Precision Operation
In recent years, increasing attention has been paid to marine environment exploration and marine resource development. Underwater robots play a crucial role in these applications due to their strong operational capabilities, cost-effectiveness and long endurance. For underwater robot motion control, waterproof performance and transmission accuracy are particularly important. This article focuses on HONPINE's star product - the customized IP68 waterproof harmonic drive motor.
How HONPINE Robot Joint Module Achieves Waterproof and Dustproof Performance
The IP67 waterproof rating indicates the joint module is completely dustproof and can withstand immersion in 1 meter of water for 30 minutes without leakage, meeting requirements for most humid and wading scenarios. Protection is achieved through multi-layer sealing design:
1,Outer shell made of high-strength alloy material
2,Specially vulcanized O-rings at joints with 30% higher sealing pressure than standard rubber rings, effectively blocking water molecule penetration
3,Internal electronic components housed in a customized waterproof compartment with integrated molding and dual sealing strips for secondary protection
4,Magnetic waterproof connectors with nano-coating for leak-proof cable connections even when mating underwater
For extreme environments like deep-sea applications at 1000-meter depths requiring IP68 rating, customized waterproof housing is necessary, increasing motor diameter by approximately 1cm. While IP68 has no defined depth and time standards, it typically requires stable long-term operation at depths beyond 1 meter with higher pressure resistance. Customized housings utilize:
1,Special titanium alloys or high-strength composite materials with 2-3 times the compressive strength of conventional materials
2,Enhanced pressure resistance and waterproof capability through thickened housing and optimized sealing structure
3,Additional pressure balancing device to equalize internal and external pressure via inert gas filling or pressure compensation diaphragm, preventing housing deformation and seepage
These waterproof joint modules excel in deep-sea operations:
1,Enabling deep-sea exploration robots to dive thousands of meters for seabed mapping and sample collection
2,Supporting offshore oil robots in challenging tasks like underwater pipeline maintenance and equipment inspection
