Trapezoidal Nuts with Round Flange for CNC and 3D Printers for CNC, 3D printer

Trapezoidal nuts with a round flange are utilized in lead screw mechanisms designed to convert the rotation of one component into the linear motion of another. These nuts can be made from materials such as aluminum, bronze, cast iron, or high-carbon structural steels and may vary in diameter, pitch, and profile angle. Typically, trapezoidal threads have a profile angle of α = 30°. For worm gear mechanisms, nuts are designed with α = 40°. Round flange nuts are manufactured from blanks produced by stamping, steel rolling, or threading and drawing methods.

Application

The trapezoidal nut with a round flange is a crucial component of a mechanical transmission system that also includes a trapezoidal screw. This mechanism is characterized by high strength, efficiency, and compact size, making it suitable for managing significant axial forces in jacks, presses, vices, and more. Additionally, nuts with trapezoidal threads can be found in feeding mechanisms, calibration devices, and in the designs of 3D printers and CNC machines.

Characteristics and Advantages

Utilizing the "screw-nut" transmission creates a highly efficient drive system. Bronze trapezoidal nuts exhibit a high coefficient of friction, which allows for self-locking properties.

Advantages of using trapezoidal nuts and screws include:

• Capability for low-speed movement to ensure high positioning accuracy.
• High load-bearing capacity of the mechanisms.
• Compactness and structural simplicity of the mechanisms built around this type of drive.
• Relatively low cost.

The most significant factor for trapezoidal screws and nuts is the diameter, which must be compatible for all elements of the final system. It is also essential to pay attention to the pitch of the threads, measured in millimeters. Other important characteristics include the thread direction, the material from which the nut is made, and the parameters of accuracy class and straightness.
