Hojama Cost-effective Lead Screws
1. Structural Characteristics of Lead Screw Pairs:​
1) Simple and compact structure, easy to process​
Composed of matching screw shaft and nut, their simple design enables compact sizing for space-constrained systems. Mature thread processing techniques reduce production difficulty and costs, facilitating mass application.​
2) Large reduction ratio (self-locking), smooth movement​
They provide significant speed reduction, with small screw shaft rotation translating to large nut displacement. Friction-induced self-locking secures the position when the driving force is removed, while operation remains stable with minimal vibration.​
3) Convenient to ensure and improve transmission accuracy​
Precision of thread profile, pitch, and alignment—controllable via mature manufacturing and post-processing like grinding—ensures high initial accuracy and room for enhancement, suiting precision machinery.​
4) Relatively large frictional resistance and low transmission efficiency​
Sliding friction between threads increases resistance, demanding greater driving force and resulting in lower efficiency compared to rolling friction-based mechanisms like ball screws, limiting high-speed/high-power use.​
5) Exist lateral clearance, with reverse idle stroke​
Radial gaps from manufacturing tolerances cause reverse idle stroke—driving parts must move a distance before reversing driven parts—impacting positioning accuracy in frequent-reversal applications.​
6) Micro and low-speed feeding has a crawling phenomenon​
Static/dynamic friction and system elasticity lead to uneven, jerky motion at micro/low speeds, hindering micro-positioning and precision machining quality.​
1) The screw shaft rotates while the nut moves axially​
Motor-driven screw rotation converts to axial nut movement, a common setup in linear actuators for displacement needs.​
2) The screw shaft rotates and moves axially while the nut remains stationary​
Screw combines rotation and axial movement (via dual-force driving mechanisms) with a fixed nut, useful in tools requiring rotational cutting and axial feeding.​
3) The screw shaft moves axially while the nut rotates​
Axial screw movement passively drives nut rotation, applied in systems converting linear motion to rotation, such as certain gearboxes.​
4) The screw shaft remains stationary while the nut rotates and moves axially​
Fixed screw guides rotating, axially moving nuts (driven externally). Nut displacement depends on rotation speed and thread pitch, suiting lifting devices or sliding platforms.
