Embodiment 1

[0081] Referring to Fig. 1, a core 11 with an outer diameter of 2.6mm is formed, the core 11 is formed by a core wire 15 formed of a metal steel wire with an outer diameter of 0.73mm, and four metal steel wires with an outer diameter of 0.36mm are spirally wound around it. The first winding layer 16 of the first winding layer 16 and the second winding layer 17 formed by spirally winding six metal steel wires with an outer diameter of 0.6 mm around it in opposite directions are formed. Next, a metallic steel wire with an outer diameter of 1.2 mm was wound helically with a gap of 2.54 mm to form the rack 12, thereby forming a toothed cable with an outer diameter of 4.65 mm. While preheating the toothed cable, a synthetic resin sheath 14 of PA12-type elastic material with a flexural modulus of 340 MPa based on ASTM D790 was formed on the outer periphery by extrusion molding, and the recessed portion 18 was set at 0.1 mm. The soundproof toothed cable of Example 1 with a diameter o...

Embodiment 2

[0083] While preheating the toothed cable obtained in Example 1, a plasticizer-added nylon 11 synthetic resin sheath 14 with a bending elastic modulus of 880 MPa was formed on the outer periphery by extrusion molding, and the recessed portion 18 was recessed by 0.2 mm, and then, a silicon emulsion was coated to obtain the soundproof toothed cable of Example 2 with a diameter of 5.0 mm.

Embodiment 3

[0085] By changing the synthetic resin sleeve 14 into TPEE with a bending elastic rate of 494MPa, and the recessed portion 18 is 0.2mm, except that the same method as in Example 1 is used to obtain the soundproof belt teeth of Example 3 with a diameter of 5.0mm cables.

Abstract

The present invention provides a noiseproof toothed cable enabling a reduction in noise generated by the contact thereof with a conduit, a reduction in use load, and manufacturable easily. This noiseproof toothed cable (10) comprises a toothed cable (13) having a core (11) formed of metal wires and a tooth line (12) formed on the outer peripheral surface of the core (11) and a tube-like resin coat (14) installed on the outer periphery of the toothed cable (13). Spaces (20) are provided between the recessed parts (18) of the resin coat and the core (11), the projected parts (19) of the resin coat is brought into contact with the tooth line (12), and the recessed amount of the recessed parts (18) of the resin coat positioned between the parts of the tooth line (12) is set to 0.1 to 0.5 mm.

Description

technical field [0001] The present invention relates to soundproof toothed cables. Background technique [0002] Patent Document 1: Japanese Patent Application Laid-Open No. 56-105109 [0003] Patent Document 2: Japanese Publication No. 58-29324 [0004] Patent Document 3: Japanese Publication No. 55-170519 [0005] Patent Document 4: Japanese Publication No. 58-13169 [0006] Patent Document 5: Japanese Publication No. 58-13171 [0007] Conventionally, a toothed cable in which a rack is formed around a coil is used in a window regulator for an automobile, a sunroof opening and closing device for an automobile, and the like. However, these toothed cables generate noise when sliding between them and the guide tube, so there is a need for a soundproof toothed cable with high durability to reduce the noise generated by the guide tube during use, and various products have been developed. [0008] Patent Document 1 discloses a soundproof toothed cable in which a synthetic re...
