In the field of modern heavy machinery, the stability and safety of equipment operation are crucial to the success of production operations. Thanks to its unique self-locking characteristics, the trapezoidal screw has become a core transmission component under high-load working conditions.
The self-locking function of trapezoidal thread screws is based on the design of the thread structure. When there is no external force driving it, due to the relatively large friction angle of the trapezoidal thread, a static self-locking is formed between the nut and the screw shaft. This self-locking prevents reverse sliding caused by gravity or vibration, ensuring the stability of the equipment when it is stationary.
II. Trapezoidal Screws Application
(1) Lifting Equipment
Trapezoidal Lead Screws are applied in cranes and lifting platforms to prevent the load from accidentally falling and ensure the safety of high-altitude operations.
(2) Construction Machinery
In the support structures of excavators and bulldozers, trapezoidal screws enable precise positioning of the robotic arm, avoiding displacement during operation and improving the operation accuracy.
(3) Industrial Production Lines
Used in heavy-duty material transportation systems, high-precision trapezoidal thread screws can ensure that the conveyor belts and fixtures remain stable under high loads, guaranteeing the continuity of the production process.
III. Key Points for Selection
(1) Load Adaptation
According to the maximum load of the equipment, reasonably select proper lead screw diameter and material to ensure that the bearing capacity meets the requirements of the working conditions.
(2) Environmental Adaptability
For complex environments such as humidity and high dust levels, select trapezoidal screws with anti-rust and wear-resistant coatings, which can effectively extend the service life of the trapezoidal screws.
(3) Ease of Maintenance
Give priority to trapezoidal screw products with a modular design, which is convenient for subsequent maintenance and component replacement and reduces downtime.
