Long Stroke Linear Module is an automated actuator designed specifically for achieving large-scale, high-precision linear motion. Its core feature is the ability to maintain stable motion accuracy and reliability within an ultra long travel range of several meters to tens of meters, perfectly solving technical problems such as insufficient rigidity, significant vibration, and decreased positioning accuracy that traditional linear modules encounter in long-distance applications.
Long Stroke Linear Module is an integrated transmission unit designed specifically for ultra long distance linear motion, typically referring to linear motion systems with a single axis stroke exceeding 1 meter (up to 10 meters or more). Its core design goal is to achieve stable and efficient linear motion under ultra long travel, balancing accuracy, rigidity, and installation convenience. It is widely used in industrial automation, logistics equipment, and special machinery scenarios that require large-scale displacement.
The structural design of Long Stroke Linear Module needs to break through the limitations of traditional short stroke modules, and the core components include:
|
Ultra long load-bearing base |
Material selection |
High strength aluminum alloy (such as 6061-T6) or steel structure is used. The aluminum alloy base reduces weight through hollow lightweight design (density is only 1/3 of steel), while enhancing rigidity through reinforced rib structure (bending strength ≥ 200MPa). |
|
Segmented splicing technology |
Modular splicing is usually used for travel exceeding 3 meters, which is connected to high-strength bolts through precision positioning pins (tolerance ± 0.01mm) to ensure that the straightness error after splicing is ≤ 0.1mm/m. |
|
|
Transmission system optimization |
Synchronous belt drive (light load high-speed) |
Choose carbon fiber reinforced synchronous belt (tensile strength ≥ 1000N/mm), combined with tension adjustment device (such as screw tensioner), to reduce belt relaxation under long stroke, with a maximum linear speed of 5m/s, suitable for loads below 50kg. |
|
Ball screw transmission (heavy-duty precision) |
For loads above 100kg, a segmented ball screw (with a maximum length of 3 meters per segment, connected through a coupling) is used, paired with a nut support seat to reduce sagging, and the positioning accuracy can reach ± 0.05mm (with closed-loop feedback). |
|
|
Rack and pinion transmission (super load) |
Gear and rack meshing transmission,single axis load can reach over 500kg, suitable for long-distance movement of gantry cranes and large machine tools, with a speed range of 0.1-2m/s. |
|
|
Dual rail support system |
Double rails |
Adopting parallel double linear guide rails (such as HIWIN MG series) or heavy-duty roller guide rails (such as THK RA series), the guide rail spacing is optimized according to the load center of gravity to reduce the tilt caused by unbalanced load (tilt error ≤ 0.02 °). |
|
Slides |
The number of sliders is increased to 2-4 groups, and the load is distributed through a load sharing mechanism, resulting in a 40% increase in dynamic rigidity. |
|
|
Intelligent auxiliary components |
Intermediate support seat |
An adjustable support seat is set every 1-2 meters, and the deformation of the base is compensated for by height adjustment bolts (deflection ≤ 0.5mm/meter). |
|
Anti collision and limit |
High precision limit switches (response time ≤ 5ms) are installed at both ends, combined with buffers (such as polyurethane dampers) to absorb impact energy and protect equipment safety. |
