Machida Gear Manufacturing Co., Ltd. Gear Product Case Studies

basic information

【Examples of Gear Products】 ○ Spur Gear → A cylindrical gear with teeth cut parallel to the rotation axis. → A gear with tooth profiles parallel to the axis on the cylindrical surface. → It is easy to manufacture and assemble, making it the most commonly used for power transmission. ○ Helical Gear → A cylindrical gear with tooth profiles in a helical shape. → It has excellent strength and produces less vibration and noise. ○ Internal Gear → A gear with teeth formed on the inner circumference. ○ Pump Gear → An important component that forms a mechanism to trap liquid or air in the space between the case and the gear for suction and discharge. ○ Sprocket → A gear used in bicycles, motorcycles, and film feeding components in movies. ○ Spline Shaft → A gear that changes the engagement of teeth by moving along the shaft, often used in cases for shifting. ○ Worm Gear and Worm Wheel → Used in telescopes and microscopes for fine adjustments due to the large reduction ratio obtained in one stage. ○ Ground Gear → Excellent in transmission rate and quietness, and can reduce environmental impact. ● For more details, please contact us or download the catalog.

Detailed information

• 

  Internal gear is a type of gear with teeth formed on the inner circumference, which transmits rotational force in the same direction by meshing with a smaller external gear. It is often used in reduction gears and allows for a compact arrangement of the entire device due to its shape.

• 

  Pump gear It is an important component that constitutes a mechanism for trapping liquid or air in the space created between the case and the gear by rotating a combination of gears called drive gear and driven gear, allowing for suction and discharge. Those using oil are hydraulic pumps, while those using air are air compressors. In both cases, precision of the gear end faces is required to ensure a tight seal.

• 

  Worm gear and worm wheel A worm gear is a type of gear that combines a worm, which is like a screw made on a round rod, and a worm wheel that meshes with it. It provides a large reduction ratio in a single stage, making it suitable for fine adjustments in telescopes and microscopes.

• 

  Tooth-ground gears are those that have undergone grinding processing after being cut using hobbers or gear shapers. This process is mainly performed after heat treatment to remove heat treatment deformation and improve meshing accuracy. Compared to those that have only undergone cutting, they excel in transmission efficiency and quietness, and due to their reduced environmental impact, demand has been increasing in recent years.
