MESSAGE
A planetary gearbox is a mechanism designed to reduce motor speed while increasing torque. Its internal planetary gears are the core components of the gearbox, and special attention must be paid to lubrication when operating under extreme high or low temperatures. A high-quality, fully synthetic grease should possess the following four key functions to meet the lubrication requirements of planetary gears.
1. Lubrication and Wear Protection
During high-speed operation, the teeth of planetary gears engage and rub against each other rapidly, which can accelerate gear wear. Using grease forms a lubricating elastic film on the gear surfaces, reducing direct metal-to-metal contact and friction, thereby minimizing gear tooth wear.
2. Enhance the Durability of Planetary Gear Contact Surfaces
The contact stress on gear teeth is a primary factor leading to reduced gear strength. The lubricating film formed by grease helps distribute the stress across the gear surface, thereby improving the durability of the gears.
3. Prevent Adhesive Gear Surface Damage
Adhesion is a common failure mode in gear transmissions. Specifically, when the load and speed on the gear mesh exceed the limit that the lubricating film can withstand, the film may rupture, causing direct friction between the contacting gear surfaces and resulting in wear. As friction intensifies, the temperature of the gear surfaces rises rapidly, which may lead to adhesion and gear surface damage. Grease, with its anti-adhesion properties, load-bearing capacity, and extreme pressure (EP) characteristics, ensures effective separation between gear teeth, effectively preventing adhesive damage.
4. Reduce Transmission Noise and Vibration
Gear vibration and noise can arise from multiple factors, making the choice of grease particularly important. A suitable gear grease, due to its viscosity, can significantly reduce gear vibration, impact, and noise. However, the effect on vibration and noise may vary depending on the lubrication method and the specific type of grease used.
EUBO PUR Hot Melt Adhesive is a versatile, single-component reactive hot melt adhesive. It exhibits excellent initial tack at room temperature and shows outstanding compatibility with a wide range of substrates, including plastics, metals, ceramics, and inorganic glass, quickly achieving positioning strength in a short time.
This product is especially suitable for bonding frames and display screen bezels in various consumer electronics, particularly for adhesion between metal frames and plastic parts. Its fast curing and high initial tack provide significant pressure-free bonding benefits (eliminating the need for traditional pressing steps), while maintaining pressure-sensitive characteristics for approximately 10 minutes after dispensing, facilitating easy positioning and handling.
Single-component, Solvent-free: Convenient to use, environmentally friendly, and safe.
Enhanced Production Efficiency: Shortens assembly time, improving efficiency, throughput, and product yield.
Excellent Mechanical Performance: After curing, the adhesive forms a tough matrix, providing outstanding drop-resistance for the final product.

PCB assembly and protection
Post-dispensing Cleanup: Wait until the adhesive cools to room temperature, then remove any excess adhesive that has overflowed at the edges.
Uncured Adhesive Removal: Any remaining uncured adhesive can be scraped off using a blade.
Solvent Wiping: If wiping is necessary at the dispensing site, common cleaning solvents such as toluene or acetone can be used.
Timely Cleaning: Ensure adhesive residues are removed before the adhesive is fully cured.
Heating and Usage Duration: Do not repeatedly heat the adhesive. Once opened, it must be used within 8 hours. Continuous single-time heating should not exceed 8 hours.
Temperature Control: The operating temperature should not be set too high and must be ≤ 130°C to prevent the risk of tube rupture under high temperature and pressure.
Safety Protection: Take care to avoid burns during operation.
Storage Conditions: Store the product in a dry environment with a temperature between 15–25°C.
Packaging Requirements: The product should be kept in vacuum-sealed aluminum foil bags.
Shelf Life: Under the above storage conditions and unopened, the product has a shelf life of 6 months.
Potting adhesives are indispensable materials in the electronics industry, playing a key role in ensuring the safety, reliability, and longevity of electronic products. Their necessity can be highlighted in the following aspects:
Enhanced Protection and Structural Strength:
Physical Protection: After curing, potting adhesives form a protective layer that significantly enhances the overall structural strength of electronic components, improving resistance to external impacts, vibrations, and mechanical stresses.
Environmental Sealing: They effectively prevent direct exposure of internal components and circuits, providing excellent barriers against water, moisture, dust, and corrosion, thus protecting delicate circuitry from harsh environments.
Improved Electrical Performance and Miniaturization:
Reliable Insulation: Potting adhesives greatly enhance insulation between specialized internal components and complex circuits, preventing short circuits and leakage, ensuring safe operation of the device.
Facilitates Miniaturization: The filling and protection provided by potting adhesives help secure micro-components, supporting lightweight and compact design in electronic products.
Addressing Thermal Challenges:
Modern electronic products feature high precision and high power density, which can easily lead to excessive component temperatures, causing failures and shortening product lifespan.
Potting adhesives—especially thermally conductive types—act as a critical thermal management medium. When applied inside electronic products, they efficiently transfer heat generated by internal components to the casing, significantly improving overall heat dissipation performance.
Ensuring Comprehensive Performance:
High-quality potting adhesives not only provide excellent shock resistance, sealing, and thermal conductivity after curing, but also offer good heat resistance, flame retardancy, weatherability (resistance to thermal cycling, UV, etc.), and long-term stability.
