You have many options when using mechanical power systems. Learning basic gear terminology helps you pick the right Custom Gear for your job. Dongguan Yongfeng Gear Co., Ltd. makes gears that are accurate and strong for industries like cars and robots. The custom gear market should grow by 4.7% each year for five years. If you know gear terminology, you talk better, design better, and work better.
Learning basic gear words helps you pick the best custom gear for your project.
Gear types, such as spur and helical gears, do different jobs and have special benefits.
Knowing about pitch circle and module is important to make sure gears fit together well and work smoothly.
Keeping backlash low is needed to keep gears accurate and stop them from wearing out fast.
Choosing the right gear ratio and gearbox can make machines work better and help avoid expensive fixes.
A gear helps move power between machine parts. It is round and has teeth that are spaced the same. These teeth fit with other gears to work smoothly. Some gears look different for special jobs. Gears are in many machines like cars and robots. Knowing gear words helps you pick the right part.
Dongguan Yongfeng Gear Co., Ltd. makes custom gears for many uses. They make spur gears, helical gears, bevel gears, and internal gears. These gears are used in cars, automation, and robots.
Gears help move power from one part to another. The table below shows how gears work:
Principle/Type | Description |
|---|---|
Gear Types | Gears can be spur, bevel, or worm gears. |
Lubrication | Gears need oil to stop friction and damage. |
Mechanical Power Calculation | Power is found by force and speed or torque and speed. |
Gearbox Operation | Gearboxes change speed and torque with gears. |
Gears change speed, direction, and force. Picking the right gear helps your machine work well and last longer.
There are many kinds of gears for different jobs. Each gear type has its own features. The table below shows common gears and what they do:
Gear Type | Speed | Torque | Direction of Motion | Good in Limited Spaces | Reduces Noise & Vibration | Can Handle Heavy Loads |
|---|---|---|---|---|---|---|
Spur Gears | High | Medium | Parallel | No | No | Yes |
Helical Gears | High | High | Parallel/Angled | No | Yes | Yes |
Rack Gears | Variable | High | Linear | Yes | No | Yes |
Bevel Gears | Variable | High | Perpendicular | Yes | No | Yes |
Miter Gears | Fixed (1:1) | Medium | Perpendicular | Yes | No | Not for Heavy Loads |
Worm Gears | Low | High | Perpendicular | Yes | Yes | Yes |
You choose a custom gear for special needs. Custom gears fix problems that regular gears cannot. They give better speed, torque, and strength.
Tip: If you know gear words and types, you can pick the best gear for your project.
Understanding gear terminology helps you make better choices when working with gear mechanisms. Each term below plays a key role in how types of gears work together in a gear train.
The pitch circle is an imaginary circle that sits at the center of the gear. You measure its radius from the gear’s center to the pitch point, which is where the gear’s speed is measured. This circle passes through the pitch point of each tooth and forms the main reference for gear geometry and tooth spacing.
The pitch circle shows where two gears touch and transfer power.
The pitch diameter decides the size of the gear and the size of its teeth.
Proper tooth size from the pitch diameter helps gears mesh well and share loads evenly.
The pitch circle affects the strength and load capacity of the gear.
When you select a custom gear, you must know the pitch circle to ensure your gear mechanisms work smoothly.
The module is a number that tells you how big the gear teeth are. You find it by dividing the pitch diameter by the number of teeth. The module helps standardize gear sizing, so gears from different sources can fit together.
Aspect | Description |
|---|---|
Definition | The gear module is the ratio of pitch diameter to the number of teeth of a gear. |
Standardization | It standardizes gear sizing, ensuring consistency and compatibility between gears. |
Role in Manufacturing | Ensures gears from various sources fit together seamlessly. |
Impact on Performance | Affects strength, size, and functionality of gears. Higher modules yield robust gears but increase size and cost. Smaller modules allow compact designs but may reduce load capacity. |
Benefits | Proper selection leads to reduced wear, increased efficiency, and longer service life. |
A larger module means bigger teeth, which can handle more torque and are stronger.
A smaller module gives you finer teeth, which work well in high-precision gear mechanisms but carry less load.
The module controls the size and strength of the gear teeth, so picking the right value keeps your gear train reliable.
Addendum and dedendum are two important words in gear terminology. They describe the distances from the pitch circle to the top and bottom of the gear teeth.
Term | Definition |
|---|---|
Addendum | The radial distance between the pitch circle and the addendum circle, equal to 1 module. |
Dedendum | The radial distance between the pitch circle and the dedendum circle. |
The addendum and dedendum decide how well the teeth of two gears fit together. If these distances are not correct, the teeth may not mesh smoothly. Good proportions help the teeth engage without rubbing or getting stuck. This reduces friction and wear, and it spreads the load across the teeth. If the addendum or dedendum is wrong, you may see more stress and less performance in your gear mechanisms.
Tip: Always check the addendum and dedendum when designing or choosing types of gears for your project.
The pressure angle is the angle between the line of action (where the teeth push against each other) and a line that is tangent to the pitch circle. Most industrial gears use a pressure angle of 14.5° or 20°, with 20° being the most common today.
You pick the pressure angle based on how the gear will be used and how it is made.
Lower pressure angles, like 14.5°, make the gear run more quietly, reducing noise by about 3-5 dB.
Higher pressure angles, such as 30° or 35°, make the gear teeth stronger and reduce bending stress, which helps in heavy-load gear mechanisms.
In high-speed gear trains, efficiency matters more, but for heavy loads, strength is more important.
Choosing the right pressure angle helps you balance noise, strength, and efficiency in your gear mechanisms.
Backlash is the small gap or play between the teeth of two gears. This gap is important for the function, efficiency, and life of gear-driven machines.
Backlash lets the gears move without binding, but too much can cause noise, wear, and lost motion.
Too little backlash can make the gears stick, increase friction, and cause overheating.
Excessive backlash makes the gear train less precise and increases wear.
Not enough backlash can make the teeth clash, leading to early wear and noise.
You must control backlash carefully in custom gear systems to keep your gear mechanisms running smoothly and reliably.
Note: Understanding gear terminology like backlash helps you design gear mechanisms that last longer and work better.
When you pick a gear, you need to think about many things. The gear must move rotation and torque without breaking. Using the wrong gear ratio can cause problems. Not knowing gear words can lead to mistakes. Companies lose time when gears do not fit or shafts are not lined up. These issues can make machines shake, wear out, or break down.
Here is a table that shows what to check for heavy jobs:
Criteria | Description |
|---|---|
Service Factor | Checks if the gearbox can handle your load and working hours. |
Ambient Temperature and Environment | Looks at how heat or cold affects gear performance and lubrication. |
Shock Load or Type of Load | Considers if your load changes suddenly, which can wear out gears faster. |
Output Style or Mechanism | Makes sure the output matches your machine’s needs for torque and rotation. |
Output Shaft or Hollow Bore Size | Ensures the shaft size fits your system and keeps costs down. |
Choosing the right gear ratio and gearbox helps your machine work well. It also stops expensive repairs.
Tip: Always check your gear design and basic gear mechanisms before you put in new gears.
Sometimes, you need special gears for certain jobs. In cars, custom inserts keep engine parts from slipping. Plastic carriers protect batteries from shaking and damage. Some companies use special holders for drive parts to stop shocks and water. These custom gears help move rotation and torque in hard places.
Dongguan Yongfeng Gear Co., Ltd. makes custom gears for many uses. You can pick spur, helical, or bevel gears. If you need a planetary gearbox for robots, you get exact gear ratio control and smooth movement. In automation, you may want a gearbox that moves fast and stays quiet. Custom gear design lets you match gear ratio, torque, and shaft size to your needs.
You want your gear systems to last a long time. To check if they are strong, you look at bending strength, surface durability, and pitting resistance. These show if the gear can handle torque and keep moving under heavy loads. Here is a table with important checks:
Metric | Description |
|---|---|
Bending Strength | Shows if the gear tooth can resist breaking during rotation. |
Surface Durability | Checks if the gear can avoid pitting when teeth transmit power. |
Pitting Resistance | Measures how well the gear resists wear during continuous rotation. |
Gears can fail from bending, wearing out, or scuffing. You can stop these problems by using strong materials, keeping the gearbox clean, and making sure the gear ratio and fit are right. Good gear design and the right planetary gearbox help you move rotation and torque with less chance of breaking.
Note: If you know gear words and gear design, you make better choices. Your machines move power, move rotation, and last longer.
Knowing important gear words helps you make good choices in projects. The table below lists some key words you should learn:
Term | Description |
|---|---|
Face Width | How long the gear teeth are across the gear. |
Pitch Circle | An invisible circle where two gears touch each other. |
Addendum | How tall the gear teeth are above the pitch circle. |
Dedendum | How deep the gear teeth go below the pitch circle. |
Dongguan Yongfeng Gear Co., Ltd. checks quality and uses modern machines to make strong custom gears. You can get better results if you ask experts, use books like Dudley’s Handbook of Practical Gear Design and Manufacture, and pick certified companies. Keep learning and watch the small things to help your gears work better.
A mechanism is a group of parts that work together to move or control something. You see a mechanism in machines, toys, and even doors. Each mechanism uses motion to do a job.
You need different mechanisms because each one does a special job. Some mechanisms change speed. Others change direction. Some mechanisms help you lift heavy things. Using the right mechanism makes your machine work better.
A mechanism moves power from one part to another. When you use a mechanism, you can change how fast or how strong something moves. This helps machines do work more easily.
Yes, a mechanism can make machines safer. Some mechanisms stop parts from moving too fast. Others keep things from breaking. You use a mechanism to control motion and protect people.
A gear is a wheel with teeth. You use a gear in a mechanism to change speed, direction, or force. Gears help mechanisms work smoothly and do more jobs.
