Introduzca

The differential pinion seal is a seal used in the differential system. It is placed around the differential’s pinion gear to seal and safeguard it. A differential is a part of the powertrain of a car that helps to balance and distribute power to the driving wheels. Preventing leaks of transmission fluid or lubricating oil from the differential’s pinion gear and preventing outside impurities from getting inside the differential system are the primary purposes of it. For enduring and reliable sealing performance, they are composed of rubber that is both oil- and wear-resistant.

  • The International Organization for Standardization (ISO) created ISO 9001, a certification standard for quality management systems, to make sure that businesses adhere to quality management guidelines throughout the design, development, production, and service delivery phases.
  • A technical specification for quality management systems used in the global automobile sector is ISO/TS 16949. It targets the quality management needs of automakers and their supply networks and is used in combination with ISO 9001.
  • The American Society for Testing and Materials (ASTM) developed ASTM D2000, a specification for rubber products that covers the chemical and physical characteristics, heat and oil resistance, and other characteristics of various rubber materials.
  • The Society of Automotive Engineers (SAE) created SAE J200, a rubber material specification that addresses the chemical, physical, and thermal resistance characteristics of various rubber compounds.

Ventaja y función

  1. Sealing performance: The main function of the differential pinion seal is to provide a sealing effect, prevent lubricating oil or transmission fluid from flowing out from the pinion gear of the differential, ensure that the lubricating oil within the differential system is kept in place, and prevent external contaminants enter the system.
  2. Parts protection: By lowering friction and wear, the seal extends the differential system’s service life by using its sealing ability to stop lubricant leaks and safeguard important components from wear and damage. expand.
  3. Prevent leakage: If lubricating oil leaks in the differential system, it may lead to insufficient oil volume, greatly reducing the lubrication effect and increasing friction and wear between parts. The existence of differential pinion seal effectively prevents lubricating oil leakage and ensures the normal operation of the differential system.
  4. Prevent contaminants from entering: The seals also serve to prevent external contaminants from entering the differential system. These contaminants may include dust, moisture and other impurities, and their intrusion can cause the performance of the lubricating oil to degrade, thereby affecting the operation of the system and even malfunctioning.
  5. Improved efficiency: Differential pinion seal helps maintain proper circulation and use of lubricant, thereby increasing the efficiency and performance of your differential system.
  6. Wear resistance and durability: The seals are made of wear-resistant and oil-resistant materials and can withstand extreme working conditions such as high-speed rotation, high temperature and high pressure. They have good durability and can work for long periods of time in harsh conditions.

Conclusión

The differential pinion seal is a pivotal constituent of a vehicle’s powertrain, safeguarding the pinion gear against transmission fluid or lubricating oil leaks. It is composed of a rubber compound that is both resistant to oil and wear, offering long-lasting sealing capabilities. The seal is certified by ISO 9001, ISO/TS 16949, ASTM D2000, and SAE J200. Its primary objective is to curtail lubricant leakage, avert external pollutants from infiltrating, and enhance efficacy. The material of the seal, namely NBR, demonstrates a density between 1.0 and 1.2 g/cm³, a hardness rating of 20-95 Shore A, a tensile strength range of 10-25 MPa, and a flexural modulus range of 2-20 MPa. The seal’s design assures the retention of lubricating oil and prevents the ingress of external contaminants, rendering it an appropriate and dependable component in the differential system, where it exhibits remarkable wear resistance and durability, enabling it to operate efficiently even in harsh working conditions.
