Trapezoidal Lead Screw

I.Product Introduction

This product is a high-efficiency transmission core component - Trapezoidal lead screw independently developed by Lishui City Hengli Automation Technology Co.,LTD. Its core function is to accurately realize the two-way conversion between rotary motion and linear motion. The Trapezoidal lead screw can be widely used in various scenarios such as CNC machine tool feed systems, 3D printer positioning axes, solar panel tracking brackets, and vertical lifting platforms. It can not only meet the precise positioning needs of automated equipment, but also adapt to light-load control scenarios such as manual adjustment devices and medical equipment. At the same time, it can bear heavy-load transmission and adapt to heavy industry applications such as port crane lifting mechanisms, providing global customers with full-scenario transmission solutions.

II.Product Introduction & Features

1.Operation Principle

The Trapezoidal lead screw is mainly based on the spiral transmission principle. Through the trapezoidal thread meshing structure of the screw and the nut, it converts the rotary motion input by the motor or manually into the linear motion of the nut along the screw, and vice versa, it can also convert the linear driving force into rotary force to realize two-way transmission. Its trapezoidal tooth profile (usually 30° or 29°) can increase the contact area, disperse the load, reduce friction with the lubricating medium between the threads, and at the same time, rely on the self-locking characteristics of the tooth profile to ensure no slippage when powered off during vertical or inclined operation, ensuring transmission stability.

2.Product Advantages

Durable Material

Selected by Lishui City Hengli Automation Technology Co.,LTD, two materials are available: 45# steel (high strength, impact resistance) and 304 stainless steel (corrosion resistance, suitable for humid environments), which completely solve the problems of "easy rust and fast wear", and are applicable to heavy-load working conditions and humid, outdoor environments respectively.

Higher Matching Precision

Adopting precision rolling/grinding technology, the thread precision reaches C7-C10 grade, the matching gap is ≤0.05mm, the thread processing technology is optimized to avoid the problems of "transmission jamming and inaccurate positioning", and the wear rate is 30% lower than that of ordinary lead screws.

Strong Installation Adaptability

Equipped with two options of cylindrical nuts and steel flange nuts, it meets the needs of different installation scenarios, solves the pain point of "mismatched installation interfaces", and is compatible with a variety of driving components and accessories.

Stable Structure, Safe and Reliable

Retaining the self-locking advantage of the trapezoidal lead screw, it is suitable for scenarios with high safety requirements. At the same time, it reduces operating noise through precision processing and avoids the problems of "high noise and easy loosening during vertical operation".

Cost-Effective and Easy to Maintain

With an extremely simple structure and no complex accessories, the purchase cost is only 1/3 of that of ball screws. It also has strong resistance to dust and oil pollution, no need for frequent maintenance, reducing long-term use costs.

3. Specifications & Selection

The core parameters of the Trapezoidal lead screw include nominal diameter, lead, and precision grade, which can be customized according to customers' actual needs to adapt to different transmission speeds and load requirements, with a maximum load of up to 50kN and a maximum speed of ≤1500rpm.
