Worm Shaft
Item Name Code (INC) 18249
 |
A drive shaft having helical thread(s) on a portion of its outer surface, machined bearing surface(s) and facilities for driving (other than a hub) on one or both ends of shaft. Designed to mate with a cam, gear sector, worm wheel, etc. Includes items with bearings. Excludes items having more than one worm complement of helical threads, items with a separate complement of gear teeth, and GEAR, WORM.
Additional Information for Worm Shaft
A worm shaft is a type of mechanical power transmission component that is commonly found in the supply class of Miscellaneous Power Transmission Equipment within the supply group of Mechanical Power Transmission Equipment.
A worm shaft consists of a cylindrical shaft with a spiral thread, known as a worm, wrapped around it. The worm has a helical shape, resembling a screw, and is typically made of hardened steel. The worm shaft is designed to transmit rotational motion and power between two perpendicular shafts, known as the worm gear and the worm wheel.
The worm gear is a cylindrical gear that meshes with the worm, while the worm wheel is a toothed wheel that is driven by the worm gear. When the worm shaft is rotated, the worm gear rotates, which in turn drives the worm wheel. This mechanism allows for the transmission of power and motion at a right angle, making it useful in various applications where space is limited or where precise control is required.
Worm shafts are commonly used in industries such as automotive, aerospace, robotics, and machinery. They are often found in applications such as steering systems, conveyor systems, lifting equipment, and machine tools. The design of worm shafts allows for high gear ratios, which can provide increased torque and reduced speed.
It is important to note that worm shafts require proper lubrication to minimize friction and wear. They also require regular maintenance and inspection to ensure optimal performance and longevity.
Overall, worm shafts are a crucial component in the field of mechanical power transmission, providing efficient and reliable motion transfer in various industrial applications.
