Sintered Gear Applications

Sintering is a manufacturing process that uses extreme pressure to turn a mixture of powdered metals, alloys, and binding agents into a solid shape. While the process was introduced in the 1940s, many industries have since leveraged its benefits.
Sintering is commonly used in applications such as automotive and power tool gears.Although sintering is versatile and can produce many shapes, we will focus specifically on the crucially important gear components.

Gears, whether with internal or external teeth cutouts, are not only simple to look at but also diminutive in size.Despite their small form factor, they are an indispensable component of any mechanically or electrically functioning device.The history of gears dates back to the era when metals weren’t even used. Instead, big wooden structures with teeth cut into them were employed for heavy lifting tasks. As time passed, metallurgy brought alloy gears made with metals like steel and brass. Today, one can find gears in small devices like a wristwatch to big machines like a motor engine. Sintered gear applications are widespread in different industries. However, here are a few sectors that utilize them the most.

  • Automobiles

  • Power Tools

  • Medical Industry

  • Domestic Appliances

  • Outdoor Power Equipment

There are other industries such as marine where gears and their use is seen but these five have exponentially high usage rate.

  • Automobiles

    Gears are a fixture in almost all moving parts within in the drivetrain. From the gears of the vehicle itself to the fixtures inside the engine and those responsible for moving the tires, gears are everywhere in automobiles. Varying shapes and sizes gears are used and almost all of them are produced through the sintering process. When it comes to sintered gear applications, automobiles or motorized vehicle industry is the largest consumer.

  • Power Tools

    Small device that help both a normal Joe and a professional put or take off fixtures, that is the use of power tools. They are easy to use, pack a lot of power and are small enough to be mobile. All of that is possible due to multiple hears present within the device. Small gears are present in the motor of the power tool while the movement of the tool itself is conducted by a larger gear. This can vary depending on the type of power tool in use but sintered gears are applied all over power tools.

  • Medical Industry

    While the rudimentary handheld equipment used for metal purposes are at most times made of single stainless steel. Modern innovation means mechanization and that means more movable parts where gears are situated for easy movement of the machine. From surgical robots assisting doctors in life preventing ways, to modern rest and recovery best, sintered gears can be found in all of them.

  • Domestic Appliances

    Mixer, Grinder, washing machine, dryer, hair dryer, there are multiple devices found within are homes that would be useless without gears. Moving parts within the appliances communicate and work with one another with the help of gears transferring the power of the gear to the output mechanism. Most of the gears used in devices, most of the parts used in these devices, are made through sintering. One of the biggest consumers of sintered gears has been the domestic appliances industry. Almost every motorized appliance in your house has at least one.

  • Outdoor Power Equipment

    Even though not only for professionals, outdoor power equipment is used to maintain a surrounding’s appearance. Lawn mowers, hedge trimmers, chainsaws, anywhere a shaft is used to transfer power from the motor to the real-world interface, gears are used. Outdoor power equipment and their power requirement rely heavily on sintered gears.

Advantages of Sintered Gear

As it is evident, if a motor is involved, a gear is not far behind in helping transfer of that power through different designs, shapes and sizes of equipment. While there are cases where other types of gears are used, but in most cases, sintered gears are preferred and there are several reasons for that.

  • Tight Tolerance

    Sintering process involves pressing of powder alloys together with binding agents and then putting it through a furnace to fuse the particles together. This results in tight grouping of molecules and high tolerance can be achieved. In a large assembly it is important all parts correspond to a strict tolerance requirement and that can be achieved with precision. Sintered gears are, at most times, small in size and it needs to correspond with multiple interfaces within a machine so having tight tolerance can always benefit an assembly line.

  • Manufacturing Repeatability

    Sintered gear production is a closely repeatable process. Since the production involves set temperature for all, a fixed mold and uniform material, production is identical between different parts of production. There is little to no difference in the manufacturing process, a guarantee other manufacturing process cannot give, or cannot give at the same price point of production.

  • Cost

    When it comes to production, sintering is the cheapest and most assured way to get what you want. The parts are uniform, they have high tolerance, the same result can be had over and over again, all of that is to say there is little to no down time in the manufacturing process. Cost plays a vital role in production planning and sintered gears are the best when it comes to all things, especially cost.

  • Environmentally Sound

    As manufacturing has taken off all over the world, there is the concern for the environment and need to meet energy as well as climate standards. Sintered gear production is energy as well as climate additive because there is little to no waste from the sintering process. As mentioned above, sintering is an additive process, there is a machining waste like in die casting and machining processes. So, environmental concerns are turned down a little when it comes to sintered gears.
