Robotic shaft seals often operate for long periods in low-temperature environments. Many engineering cases show that oil seals performing reliably at room temperature may exhibit leakage, increased start–stop wear, and unstable sealing behavior once exposed to low temperatures. The root cause is rarely assembly-related; instead, the lip interference loses its ability to provide effective compensating force under low-temperature conditions. This article analyzes how low temperatures affect lip interference from multiple perspectives and proposes feasible design optimization strategies. 1. How Low Temperature Affects Lip Interference The sealing performance of a metal-cased oil seal depends on the lip maintaining stable contact pressure against the shaft surface. In low- temperature environments, this balance is disrupted by several mechanisms: Increased rubber modulus: Rubber becomes stiffer at low temperatures, reducing lip flexibility and making it harder to conform to the shaft surface. Differential thermal contraction: Rubber, metal casing, and shaft materials shrink at different rates, altering the effective interference. Higher lubricant viscosity: Thickened lubricant makes it difficult to form a stable oil film during startup, increasing the likelihood of boundary or even dry friction, which accelerates wear. It is important to emphasize that low-temperature seal failure is not simply a matter of “insufficient interference.” Rather, the interference can no longer deliver sustained, effective contact pressure, leading to systemic degradation of sealing performance. 2. Selecting and Optimizing Interference Interference must be carefully optimized. Some studies recommend a range of 0.35–0.55 mm to balance sealing capability and service life. For high-load or high-pressure applications, values around 0.8 mm may be more appropriate. This highlights that interference should be determined based on operating conditions (pressure, speed), material properties, shaft diameter, and validated through simulation or testing—not by blindly increasing the interference. 3. Material Selection: Low-Temperature Elastic Recovery as the Core Criterion Whether the lip can maintain effective interference at low temperatures depends primarily on the rubber’s elasticity and rebound behavior. FVMQ (fluorosilicone): Maintains excellent flexibility and elastic recovery in extreme cold while offering moderate oil resistance. Suitable for collaborative robots or cold-region drive shafts requiring high compliance. Low-temperature FKM: Retains oil and aging resistance while improving low- temperature rebound. Ideal for medium-to-low temperature applications requiring long service life and chemical compatibility. HNBR: Balances low-temperature elasticity with mechanical strength, making it suitable for outdoor equipment or machinery subjected to impact loads and durability demands. Thus, the key question is not “Is the material cold-resistant?” but “Can it still rebound at low temperatures?” 4. Spring Systems: The Primary Compensation Mechanism in Low Temperatures In low-temperature environments, rubber elasticity alone is insufficient to maintain sealing pressure. A spring-loaded structure becomes essential. An effective spring system should: Provide adequate working stroke to compensate for rubber stiffening Maintain stable force output across the low-temperature range Work synergistically with the lip geometry to distribute contact pressure In extreme low-temperature applications, seals with radial garter springs are commonly used, underscoring the spring’s role as the core compensating element. 5. Structural Design Matters More Than Increasing Interference Simply increasing initial interference often leads to higher friction and wear during low-temperature startup. A more effective approach is to enhance structural compliance so the lip can adapt to temperature changes. Examples include: Reducing lip cross-section thickness to lower bending stiffness Extending the elastic arm to improve followability and reduce stress concentration Optimizing contact angle to achieve more uniform pressure distribution and reduce edge wear The design goal is to ensure the lip can “move with the temperature,” rather than passively suffer from material performance loss. 6. Shaft Surface Condition: A Critical System-Level Factor At low temperatures, oil film formation becomes more difficult, making shaft surface condition even more influential. Optimized roughness (Ra 0.2–0.4 μm): Balances oil retention and lip conformity Micro-texturing (cross-hatch or micro-grooves): Improves start–stop lubrication and sealing stability Avoiding surface defects: Prevents early lip wear or scratching 7. System-Level Thermal Matching and Tolerance Coordination Low-temperature sealing stability requires system-level coordination, not just lip design. Key considerations include: Thermal contraction compatibility among shaft, casing, and spring Amplification of assembly tolerances at low temperatures Lubricant flow and adhesion characteristics in cold environments Only through thermal and mechanical synergy at the system level can the lip maintain effective interference throughout temperature fluctuations. There is no single “correct” interference value for low-temperature robotic shaft applications. Instead of pursuing larger interference, designers should focus on enabling the seal structure to continuously adapt to temperature changes. This system-oriented approach is far more meaningful for achieving reliable low-temperature sealing performance.
