Leno System Drive Lever Arm Assembly Carbon Fiber Connecting Rod Heald Frame Spare Part

Product Description:

• This carbon fiber connecting rod is a transmission lever of Leno System Drive Lever Arm Assembly (heald frame leno drive lever assembly). Each rod body is integrally cut from high-strength carbon fiber plate. Stainless steel threaded bushings and wear-resistant stainless steel hinge bushings are pre-installed on two ends respectively. Flexible rotation is realized via hinge structure to transfer reciprocating power within the full leno transmission mechanism and guarantee stable and precise timing of leno movement.
  Carbon fiber material greatly reduces moving weight while maintaining sufficient bending and torsion rigidity, effectively cutting inertia impact generated in high-speed reciprocating motion and lowering vibration of the whole leno mechanism. Stainless steel bushings at ends reinforce hinge positions and prevent hole enlargement and cracking caused by direct friction on carbon fiber plate, greatly extending service life. All hole center distances and mounting dimensions are machined fully according to assembly drawing, supporting direct replacement of original rods without extensive re-commissioning after installation. It adapts to long-term continuous high-speed loom weaving and dusty workshop conditions, acting as an important spare part for maintenance replacement of heald frame leno drive lever assembly.

Features:

• Lightweight carbon fiber lever: Light weight with excellent rigidity, reduce high-speed transmission inertia and suppress vibration of leno mechanism.
  Composite stainless steel bushings on both ends: Reinforce hinge points for wear resistance, avoid carbon fiber hole abrasion, enlargement and cracking.
  Standardized hole machining: All hinge dimensions interchangeable with complete lever arm assembly.
  Integral carbon fiber plate: Excellent anti-fatigue performance, resistant to deformation and fracture under long-term cyclic load.
  Pre-fitted metal bushings for direct installation, reducing on-site processing work.
  Adapt to continuous textile production: Dust and impact resistant for 24-hour non-stop high-speed weaving.

Technical Parameters:

Applications:

• This carbon fiber connecting rod belongs to heald frame matched leno drive lever assembly. It is installed on leno transmission systems of air-jet and rapier loom heald frames, acting as intermediate transmission lever to transmit reciprocating power and drive leno yarn actuator to complete selvedge weaving.
  It is suitable for production lines of home textiles and industrial fabrics requiring reinforced selvedge. If rods suffer crack, hinge hole wear or abnormal transmission, this component can be replaced individually to restore leno movement precision. Widely used in periodic inspection of loom leno mechanisms and split spare stock in textile mills. The lightweight feature makes it ideal for high-speed looms, effectively lowering overall machine load and reducing weaving noise and selvedge defects.

Support and Services:

Packing and Shipping:

• Every single rod is placed into an individual plastic bag affixed with a printed label showing part name, item number, code and quantity. All packed units are loaded into thickened outer cartons filled with cushion fillers to prevent plate bending and bushing collision damage during transit.
  Regular orders are shipped within 48 hours. Export orders can be consolidated with other assembly parts with full logistics tracking. Neutral unbranded packaging option is available.

FAQ:

• Q1: What precautions should be taken for storing carbon fiber connecting rods?
  A: Avoid scratching carbon fiber surface with sharp objects. Do not stack heavy loads which may cause bending. Keep away from acid, alkali and corrosive substances. Store in dry and normal temperature environment to prevent rust of metal bushings.
  Q2: What causes loose bushings on ends of carbon fiber rods?
  A: Looseness from factory assembly is covered by warranty. Bushing detachment caused by long-term overload or excessive tightening torque is excluded; control bolt torque during installation.
  Q3: How to reduce risk of wear and fracture for carbon fiber rods?
  A: Prevent surface scratch by sharp objects; regularly check lubrication of hinge points to avoid dry friction accelerating hole wear; prohibit long-term operation exceeding loom rated speed.
