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

Product Description:

• This part is the core transmission lever component of Leno System Drive Lever Arm Assembly, belonging to the supporting parts for the leno mechanism on loom heald frames. It adopts lightweight carbon fiber main arm paired with high-strength aluminum alloy double connecting rods and stainless steel hinge bearings. Power is transmitted via matched hinge joints to drive the whole leno mechanism for reciprocating movement and complete selvedge weaving of fabrics.
  The carbon fiber arm greatly reduces moving inertia weight while keeping structural rigidity, cutting inertia impact from high-speed reciprocating motion and lowering overall transmission load of heald frames. Blue aluminum alloy connecting rods are treated with anodization for rust and wear resistance, and the double-rod structure ensures even stress distribution during transmission. Precision bearings are pre-installed at all rotating positions for smooth operation and tiny transmission clearance, adapting to continuous loom weaving conditions steadily. All mounting holes and hinge center distances are machined strictly according to the full lever arm assembly standard. It can be directly installed as an original replacement part without extra modification or commissioning on heald frame leno linkage structure. It fits the dusty and continuous-operation production environment in regular textile workshops, acting as a key spare part for maintenance and replacement of heald frame leno transmission mechanism.

Features:

• Lightweight carbon fiber main arm: Sufficient rigidity with light weight, reduces high-speed transmission inertia, lowers load and vibration of leno mechanism.
  Anodized aluminum double connecting rods: Rust & wear resistant, dual rods distribute stress evenly to avoid long-term deformation.
  Integrated precision hinge bearings: Smooth rotation with small transmission clearance, ensure accurate and stable timing of leno movement.
  Standard assembly-oriented hole machining: Holes and hinge dimensions fully consistent with the complete lever arm assembly for direct OEM replacement.
  Compact integrated structure: Pre-assembled rods, bearings and lever simplify on-site installation work.
  Adapt to working conditions of heald frame leno system: Durable for continuous reciprocating motion and dusty environment in textile workshop

Technical Parameters:

Applications:

• This part belongs to the leno system drive lever arm assembly matched with heald frames. It is mainly installed on heald frames of rapier & air-jet looms equipped with leno devices. As the swinging execution part of leno transmission linkage, it receives front power output and drives leno yarn mechanism to reciprocate for selvedge interlocking weaving.
  It is widely used in production lines of plain, twill and home textile fabrics requiring reinforced selvedge. When failures including lever wear, loose linkage and bearing jamming occur to the full lever arm assembly, this component can be replaced separately to restore leno transmission precision. It applies to daily maintenance of loom heald frame leno mechanisms and separate spare stock for assembly parts in textile mills, realizing partial repair without replacing the whole assembly to cut part procurement cost and downtime.

Support and Services:

• Assembly compatibility check: Verify matching of hole & hinge dimensions with full Leno System Drive Lever Arm Assembly to prevent wrong installation.
  Installation guidance: Provide instructions for linkage bearing alignment and lever locking, troubleshoot jamming and poor transmission after assembly.
  1-year warranty: Free replacement for manufacturing defects such as inherent bearing jamming, structural crack and dimensional deviation under normal weaving conditions; damage from improper disassembly & overload impact is excluded.
  Separated in-stock supply: Supply single part split from the full assembly to meet customers' separate stocking demand.
  Linked supply for other assembly parts: Support one-stop procurement together with other components of the lever arm assembly.
  Online technical support: Answer questions about installation commissioning, abnormal noise and wear inspection to reduce production downtime.

Packing and Shipping:

• Single lever is wrapped with air bubble film to protect bearings and rod edges, especially prevent scratch on carbon fiber arm, then packed into shockproof inner box. Buffer filling is added in outer carton for bulk orders to avoid extrusion deformation of hinge structure in transit. Outer carton is marked with assembly name Leno System Drive Lever Arm Assembly, part specification and quantity for easy warehouse sorting.
  Regular orders are shipped within 48 hours with domestic logistics service. Export orders can be delivered together with the full assembly with full logistics tracking, ensuring carbon fiber arm and bearings free from collision damage. Neutral packaging is available.

FAQ:

• Q1: Can this part be replaced separately, or do I need to change the whole leno system drive lever arm assembly?
  A: If other connecting rods and hinge bases have no severe damage, this lever part can be replaced separately, as its dimensions fully match the assembly standard without full assembly replacement.
• Q2: What precautions should be taken for daily use of the carbon fiber lever?
  A: Avoid scratching carbon fiber surface with hard objects during installation, check bearing lubrication regularly and prevent lever fracture caused by mechanism jamming.
• Q3: What issues are covered under the warranty?
  A: The warranty covers factory defects including bearing jamming, inherent structural crack and mounting hole dimensional deviation. Damage from installation collision and high-speed overload impact is not covered.
