Worm Wheel

Worm gear/worm wheel commonly used cast tin bronze (ZCuSnl0Pl,ZCuSn6Zn6Pb3) and aluminum iron bronze (ZCuAl10Fe3), low – speed and non – important drives can utilize the cast iron (HTl50,HT200). The cast iron bronze has these properties of good friction, good adhesion resistance and slightly lower strength. The cast aluminum-iron bronze character with less friction-reducing, less glue-resistant, high strength and relative effective price. Cast iron: gray, Nodularcastiron, timely treatment for preventing the deformation. The worm wheel can be classified into 3 types: 1.Spur gears, cylindrical gears whose teeth line is parallel to the axis. 2. Helical gear, The teeth on the helical gear are cut at an angle to the surface of the gear, it also can be made into spiral gear.

 

Worm Shaft

Worm shaft has only 1 spiral line called single-head worm, otherwise if the worm shaft has 2 spiral line called double-headed worm. Single-head worm is easier to process than double-head one. However, the wear resistance is worse than double-headed worm.

How do plastic gears contribute to reducing noise and vibration?

Plastic gears contribute to reducing noise and vibration in various applications. Here’s a detailed explanation of how they achieve this:

Plastic gears possess inherent properties that help dampen noise and vibration during operation. These properties, combined with specific design considerations, contribute to the reduction of noise and vibration in the following ways:

  • Damping Characteristics: Plastic materials have inherent damping characteristics, meaning they have the ability to absorb and dissipate vibrations. When compared to metal gears, which are stiffer and transmit vibrations more efficiently, plastic gears can effectively reduce the transmission of vibrations through their damping properties.
  • Reduced Resonance: Plastic gears have the ability to attenuate resonant frequencies, which are frequencies at which vibrations can be amplified. By properly designing the tooth profile, gear geometry, and material selection, plastic gears can shift or dampen these resonant frequencies, preventing excessive vibration and noise generation.
  • Tighter Gear Mesh Tolerances: Plastic gears can be manufactured with tighter gear mesh tolerances, which refers to the amount of clearance or backlash between mating gear teeth. Tighter tolerances lead to better gear engagement and reduced impact or vibration during gear meshing, resulting in quieter operation.
  • Surface Finishes: The surface finish of plastic gears can be optimized to reduce friction and noise. Smoother gear surfaces reduce the potential for gear tooth noise and improve the overall meshing characteristics between gears. Proper lubrication or the use of self-lubricating plastic materials can further enhance the noise-reducing properties.
  • Flexibility in Tooth Design: Plastic gears offer greater flexibility in tooth design compared to metal gears. Engineers can optimize the tooth profile and modify the gear geometry to minimize noise and vibration. For example, incorporating modifications such as profile shifting, tip relief, or helical teeth can help reduce gear noise by promoting smoother and more gradual tooth engagements.

By leveraging these characteristics and design considerations, plastic gears can effectively reduce noise and vibration levels in various applications. This makes them particularly suitable for use in noise-sensitive environments, such as consumer electronics, automotive components, or office equipment.

It’s important to note that while plastic gears can contribute to noise and vibration reduction, the specific noise performance also depends on other factors within the overall system, such as gear arrangement, supporting structures, and the presence of other noise sources. Therefore, a holistic approach to noise reduction should be considered when incorporating plastic gears into a design.

What is the impact of temperature variations on plastic gears?

Temperature variations can have a significant impact on plastic gears. Here’s a detailed explanation of their effects:

1. Thermal Expansion: Plastic gears can experience thermal expansion or contraction with changes in temperature. Different types of plastics have varying coefficients of thermal expansion, meaning they expand or contract at different rates. This can result in dimensional changes, which may affect the gear’s meshing, clearance, and overall performance. It’s important to consider the thermal expansion characteristics of the specific plastic material used in the gear design.

2. Material Softening or Hardening: Plastic materials can exhibit changes in mechanical properties with temperature variations. In general, as temperature increases, plastic materials tend to soften and become more flexible, while at lower temperatures, they can become stiffer and more brittle. These changes can impact the gear’s load-bearing capacity, wear resistance, and overall durability. It’s crucial to select plastic materials that can maintain their mechanical integrity within the expected temperature range of the application.

3. Dimensional Stability: Plastic gears may experience dimensional changes or warping due to temperature fluctuations. Higher temperatures can cause plastic materials to deform, leading to misalignment, increased backlash, or reduced gear accuracy. Conversely, lower temperatures can cause contraction, resulting in tight clearances, increased friction, or gear binding. Proper design considerations, including material selection and gear geometry, can help mitigate the impact of temperature-induced dimensional changes.

4. Lubrication and Wear: Temperature variations can affect the lubrication properties of plastic gears. Higher temperatures can cause lubricants to degrade or become less effective, leading to increased friction, wear, and potential gear failure. Similarly, low temperatures can cause lubricants to thicken or solidify, hindering proper lubrication and increasing wear. Selecting lubricants suitable for the anticipated temperature range and periodic maintenance can help ensure proper lubrication and minimize wear on plastic gears.

5. Cold Flow and Creep: Some plastic materials, especially those with lower glass transition temperatures, may exhibit cold flow or creep at elevated temperatures. Cold flow refers to the gradual deformation or flow of plastic material under constant stress, while creep refers to the time-dependent deformation under a constant load. These phenomena can cause changes in gear geometry, tooth profile, or tooth engagement over time, potentially affecting gear performance and functionality. Understanding the material’s creep and cold flow characteristics is important when selecting plastic gears for applications exposed to temperature variations.

6. Impact on Lubricants and Seals: Temperature variations can also impact the performance of lubricants and seals used in gear systems. Extreme temperatures can cause lubricants to break down, lose viscosity, or leak from the gear assembly. Seals and gaskets may also be affected, leading to compromised gear housing integrity or increased friction. It’s crucial to consider temperature compatibility and select appropriate lubricants and seals that can withstand the anticipated temperature range.

In summary, temperature variations can significantly impact plastic gears by causing thermal expansion, material softening or hardening, dimensional changes, lubrication issues, cold flow or creep, and effects on lubricants and seals. Proper material selection, design considerations, and understanding the anticipated temperature range are essential to ensure the reliable and optimal performance of plastic gears in various applications.
