INSTALLATION AND USING

The chain spocket, as a drive or deflection for chains, has pockets to hold the chain links with a D-profile cross section with flat side surfaces  parallel to the centre plane of the chain links, and outer surfaces at right angles to the chain link centre plane. The chain links are pressed firmly against the outer surfaces and each of the side surfaces by the angled laying surfaces at the base of the pockets, and also the support surfaces of the wheel body together with the end sides of the webs formed by the leading and trailing walls of the pocket.

NOTICE

When fitting new chainwheels it is very important that a new chain is fitted at the same time, and vice versa. Using an old chain with new sprockets, or a new chain with old sprockets will cause rapid wear.

It is important if you are installing the chainwheels yourself to have the factory service manual specific to your model. Our chainwheels are made to be a direct replacement for your OEM chainwheels and as such, the installation should be performed according to your models service manual.

During use a chain will stretch (i.e. the pins will wear causing extension of the chain). Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel.
 

FOR CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Pitch (inches) Pitch expressed

12 48 41 14
12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

Can plastic gears withstand high torque and load conditions?

Plastic gears have certain limitations when it comes to withstanding high torque and load conditions. Here’s a detailed explanation of their capabilities:

Plastic gears can be designed and manufactured to handle a range of torque and load conditions, but their performance is generally inferior to that of metal gears in high-stress applications. The specific capabilities of plastic gears depend on various factors, including the chosen plastic material, gear design, tooth profile, and operating conditions.

While plastic gears may not be suitable for extremely high torque or heavy-load applications, they can still provide reliable performance in many moderate-load scenarios. Plastic gears are commonly used in applications with light to moderate loads, where their unique properties and advantages outweigh their limitations.

Some plastic materials, such as acetal (POM) and polyamide (nylon), offer good strength and wear resistance, allowing them to handle moderate torque and load conditions. These materials can be reinforced with additives or fillers to enhance their mechanical properties and increase their load-bearing capacity.

It’s important to note that when designing with plastic gears, engineers must carefully consider factors such as gear size, tooth geometry, material selection, and operating conditions. Reinforcement techniques, such as using metal inserts or reinforcing fibers, may be employed to improve the strength and load-bearing capabilities of plastic gears in certain applications.

In high torque or heavy-load applications, metal gears, particularly those made from steel or other high-strength alloys, are generally preferred due to their superior strength and durability. Metal gears offer higher load capacities, better resistance to deformation, and increased resistance to wear under extreme conditions.

Ultimately, the suitability of plastic gears for high torque and load conditions depends on the specific requirements of the application and the trade-off between the benefits of plastic gears, such as weight reduction and noise reduction, and the higher load-bearing capabilities of metal gears.

It’s recommended to consult with gear manufacturers or mechanical engineers to determine the most appropriate gear material and design for a particular application, especially when high torque and load conditions are expected.

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.
