Why pinion is weaker than the gear made of same material?

When the different materials are used, the product of decides the weaker between the pinion and gear. The Lewis form factor is always less for a pinion compared with gear. When the same material is used for the pinion and gear, the pinion is always weaker than the gear.

Which is stronger gear or pinion?

Simple answer is Gear tooth on pinion has to undergo more no ( reduction ratio times) of load cycles than tooth on gear. Therefore it needs to have higher fatigue life, hence Pinion tooth is designed to be stronger.

What is the main advantage of single helical gear what is the remedy?

They cannot transfer power between non-parallel axes. Spur gears generate too much noise when operated at high speeds. The wheel’s teeth experience a great amount of stress. They cannot be used for transferring energy over long distances.

Which material is used for gears?

Gears are made of variety of materials depending on the requirement of the machine. They are made of plastic, steel, wood, cast iron, aluminum, brass, powdered metal, magnetic alloys and many others. The gear designer and user face a myriad of choices.

What are pinion gears made out of?

The pinion gear is made of case carburized steel with low nickel and chromium content and it also has undergone extensive corrosion due to an environmental problem. The teeth are badly damaged and corroded at the surface.

Which properties are necessary for gear material?

1. Material selection

• Dynamic characteristics (tensile, compression, bending, twisting)
• Hardness (hardenability)
• Change in size (temperature, etc.)
• Corrosion resistance (plating)
• Conductivity.
• Heat resistance.
• Magnetism / non-magnetism.
• Specific gravity (increase/decrease weight)

What is the difference between a pinion and a gear?

If gear and pinion are made of same material, pinion is the weaker member and design is based on its strength. But if those are made of different materials, the gear or pinion having lesser value of [σb] is weaker, as m and b are same for pinion and gear.

How to choose the right pinion for your vehicle?

The driving pinion is always subject to greater wear, therefore the pinion should always be of the more wear resistant material (e.g., steel pinion/plastic gear wheel; PA pinion/ POM gear wheel). Automatic lubrication will improve the break-in performance and the overall lifetime considerably.

What is the recommended surface quality of the driving pinion?

We recommend a surface quality of R t = 8 to 10 µm, both for dry and lubricated applications. The driving pinion is always subject to greater wear, therefore the pinion should always be of the more wear resistant material (e.g., steel pinion/plastic gear wheel; PA pinion/ POM gear wheel).

Is the pinion stronger than the gear in spiral bevel gears?

Make pinion stronger we are using hy Yes In general we can say that Pinion is weaker than the Gear in Spiral Bevel Gears means the strength factors and pitting factors for safety in Gear is more than that of Pinion. To overcome the problem of root braking or Pitting in the Pinion ie.
