Product Descripion
     The transmission gear of SZ Cone Double Screw Extruder is a mechanical transmission gear specially designed as a mating device for the cone double screw plastic extruder. The device can transmit the power generated by the major motor to the long axis of the distributor case after speed reduction and twist increasing in the transmission case. Then the long axis drives the minor axis through a pair of small-cone-angle spiral gear with a transmission ratio of 1: 1. The long axis and the minor axis with the same corner dimension as the screw bolt and in the manner of inverted outward rotation drive the screw bolt to extrude high-quality products.
     The transmission case is designed according to the standard of JB / T9050.1_1999. The gears and axial parts are made of high strength alloy steel. The gear goes through the process of carburization, heat hardening and gear grinding, with the gear precision of grade 5 and the tooth surface hardness of HRC54-62. All the oil seal adopts imported products. Both the transmission case and the distributor case are equipped with cooling coils, which are used to cool the lubricating oil.
    Due to the new improvements in gear precision and bearing configuration compared with the traditional products, its overall performance is superior to that of the current products.

Contribution of Plastic Gearboxes to Reducing Wear and Tear on Machinery

Plastic gearboxes play a crucial role in minimizing wear and tear on machinery by offering the following benefits:

  • Self-Lubrication: Many plastic materials used in gearboxes have inherent self-lubricating properties. This reduces the need for frequent lubrication, prevents dry friction, and minimizes the chances of component wear.
  • Low Friction and Low Wear: Plastic gearboxes often exhibit lower friction coefficients compared to metal gearboxes. This characteristic results in reduced abrasive wear between gear teeth and other moving parts, prolonging the lifespan of the gearbox and the machinery it operates.
  • Resistance to Corrosion: Plastics are inherently resistant to corrosion, rust, and oxidation. Plastic gearboxes are well-suited for applications in humid, wet, or corrosive environments, where metal components might be susceptible to deterioration.
  • Shock Absorption: Plastic’s inherent ability to dampen vibrations and shocks helps absorb impacts and sudden loads, preventing excessive stress on gear teeth and other components. This feature is particularly beneficial in applications with frequent start-stop cycles or varying loads.
  • No Metal-to-Metal Contact: Plastic gearboxes eliminate the need for metal-to-metal contact between gear teeth. This reduces the likelihood of galling and pitting, common issues in metal gearboxes that can lead to accelerated wear.
  • Reduced Noise and Vibrations: The damping properties of plastic contribute to quieter operation and reduced vibrations, which can further reduce the strain on components and extend their lifespan.

By mitigating factors that contribute to wear and tear, plastic gearboxes help maintain machinery in better condition, leading to increased reliability, longer service life, and reduced maintenance requirements.

Suitability of Plastic Gearboxes for Industrial and Consumer Applications

Plastic gearboxes offer versatility and are well-suited for both industrial and consumer applications due to their unique properties:

  • Industrial Applications: Plastic gearboxes find applications in various industrial sectors, such as automotive, packaging, food processing, and automation. They are suitable for light to moderate load applications where corrosion resistance, noise reduction, and customization options are important.
  • Consumer Applications: Plastic gearboxes are also widely used in consumer products, including household appliances (e.g., blenders, mixers, washing machines), power tools, garden equipment, and toys. Their lightweight construction, lower noise output, and cost-effectiveness make them popular choices in these applications.

While plastic gearboxes may not be suitable for heavy-duty industrial applications with high torque and load requirements, advances in plastic materials and manufacturing processes have expanded their capabilities, allowing them to handle more demanding tasks than before. Ultimately, the choice between using plastic or metal gearboxes depends on the specific needs and performance criteria of the application.

Design Considerations for Plastic Gearboxes vs. Metal Gearboxes

Designing plastic gearboxes involves unique considerations compared to metal gearboxes:

  • Material Properties: Plastic materials have different mechanical properties than metals, affecting factors like strength, wear resistance, and temperature stability.
  • Load Distribution: Plastic gear teeth may have different load distribution characteristics, influencing gear profile design and tooth thickness.
  • Lubrication: Plastic materials may require specialized lubrication or self-lubricating additives to reduce friction and wear.
  • Clearances and Tolerances: Clearances between plastic gear teeth may differ from those in metal gears due to variations in thermal expansion and material properties.
  • Heat Dissipation: Plastics have lower heat conductivity than metals, requiring efficient heat dissipation designs to prevent overheating.
  • Noise and Vibration: Plastic gearboxes may produce different noise and vibration levels, necessitating damping measures or gear profile adjustments.
  • Environmental Factors: Plastic gearboxes may be more susceptible to degradation from UV exposure, chemicals, or moisture, influencing material selection and housing design.

Considering these factors ensures that the design of plastic gearboxes meets the specific requirements and challenges posed by the material, enhancing their overall performance and reliability.

Limitations of Maximum Torque Handling in Plastic Gearboxes

While plastic gearboxes offer numerous advantages, they do have limitations when it comes to handling maximum torque:

  • Material Strength: Plastic materials generally have lower tensile strength and fatigue resistance compared to metals. This can limit the amount of torque that plastic gearboxes can transmit before experiencing deformation or failure.
  • Size and Design: The size and design of plastic gear teeth play a significant role in torque handling. Smaller gear teeth with less surface area may struggle to withstand high torque loads without premature wear or damage.
  • Temperature Sensitivity: High temperatures can negatively impact the mechanical properties of plastics, potentially leading to a reduction in their torque-carrying capacity. Extreme temperature fluctuations may exacerbate this limitation.
  • Operating Conditions: The operating environment, such as exposure to harsh chemicals, abrasive particles, or excessive moisture, can affect the integrity of plastic gear materials and reduce their ability to handle high torque loads.
  • Application Type: Plastic gearboxes are better suited for applications with moderate torque requirements. High-torque applications, such as heavy industrial machinery, may exceed the capabilities of plastic gearboxes.

It’s important to consider the specific torque demands of an application and select an appropriate gearbox material accordingly. While plastic gearboxes are lightweight, cost-effective, and suitable for many applications, they may not be the ideal choice for extremely high-torque scenarios.

Types of Plastics Commonly Used in Manufacturing Plastic Gearboxes

Several types of plastics are commonly used in the manufacturing of plastic gearboxes, each offering specific properties and advantages:

  • Polyamide (Nylon): Nylon is a popular choice due to its excellent wear resistance, low friction, and good impact strength. It can handle moderate loads and is suitable for various applications.
  • Polyoxymethylene (Acetal): Acetal provides high stiffness, low friction, and good dimensional stability. It is often used for small gears and low-load applications.
  • Polyethylene (PE): PE offers low friction, good impact strength, and chemical resistance. It’s suitable for applications with light loads and low speeds.
  • Polycarbonate (PC): PC provides high impact resistance and transparency. It’s used in applications requiring good visibility and moderate load-bearing capacity.
  • Polyphenylene Sulfide (PPS): PPS offers high temperature resistance and chemical resistance. It’s suitable for applications in demanding environments.
  • Polyetheretherketone (PEEK): PEEK is a high-performance plastic with excellent temperature and chemical resistance. It’s used in high-temperature and harsh environments.

The choice of plastic depends on the specific requirements of the application, including load, speed, temperature, and environmental factors.
