Gears, Cogs, and Sprockets
Quaker City Castings supplies castings in a wide variety of materials to the gears manufacturing industry in parts up to several thousand pounds finished weight. Our broad range of ferrous materials and nickel-alloys combined with our familiarity with varying teeth designs makes us uniquely suited to supply a range of customer needs.
Applications of Gear Castings
Our gear castings are essential for various industries, providing durability and precision for critical components.
- Automotive: Transmission and engine gears.
- Industrial Machinery: Heavy-duty gears for various machinery.
- Aerospace: High-performance gears for aircraft systems.
- Agricultural Equipment: Gears for tractors and other farm machinery.
Although the casting process is used most often to make blanks that will have cut teeth, there are several variations of the casting process used to make toothed gears with little or no machining. Quaker City Castings has a broadly experienced team of engineers and foundry staff to ensure that all the chemical and mechanical requirements for your parts are met and that all necessary destructive and non-destructive testing is timely performed.
Benefits of Cast Gears
Casting gears offers numerous advantages, making it a preferred method for many applications.
- Cost-Effective: Reduces machining costs by casting closer to the final shape.
- Versatility: Suitable for various materials and sizes.
- Precision: Ensures high-quality and accurate gear production.
- Strength: Produces durable and wear-resistant gears.
For example, cast-tooth internal gears can be produced in several sizes up to several thousand pounds. They are heat-treated to strength levels of 689 MPa (100 ksi) and machining is not required on these gears. In circumstances where machining is necessary, the machining expense is reduced by casting closer to the final shape.
Casting Methods for Gears
Various casting methods are employed to produce high-quality gear blanks and toothed gears.
- Sand Casting: Commonly used for producing blanks.
- Shell Molding: Suitable for precision castings.
- Permanent Mold Casting: Used for high-volume production.
- Centrifugal Casting: Ideal for cylindrical parts.
- Investment Casting: Provides excellent surface finish and dimensional accuracy.
Most casting processes have been used to produce blanks or cast tooth gears including sand casting, shell molding, permanent mold casting, centrifugal casting, investment casting, and die casting. Cut gears have also been produced from continuously cast bars. Sand casting is one of the more commonly used casting methods in this market and is used primarily to produce blanks. In recent times, there has been only very limited use of gears with teeth made by sand casting. In some instances, gears for farm machinery, stokers, and some hand-operated devices have used cast teeth. The draft on the pattern and the distortion on cooling make it difficult to obtain much accuracy in cast iron or cast steel teeth.
