Embodiment Construction

[0023] Hereinafter, the toothed cable of the present invention will be described in detail with reference to the drawings.

[0024] Such as figure 1 As shown, the toothed cable 1 of the present invention includes: a core cable 2; a rack 3 wound helically on the outer peripheral surface of the core cable 2; and a resin that continuously covers the core cable 2 and the rack 3 on the outer side (outer peripheral surface) of the covering layer 4.

[0025] As long as the core cable 1 has stretch resistance and torsion resistance, the same core cable as the core cable conventionally used for toothed cables can be used. In particular, although its structure is not limited, it can The core wire is formed by spirally winding a reinforcement layer composed of a plurality of metal wires around a core wire composed of a single metal wire, and then spirally winding another reinforcement layer composed of a plurality of metal wires around it. Cable 1.

[0026] The rack 3 is formed by he...

Abstract

The present invention has an object of providing a toothed cable 1 not to cause an unnecessary load on a motor or the like, not to cause tear in the cover layer and to have excellent durability. The present invention provides a toothed cable 1 comprising a core cable 2, and a tooth line 3 helically wound on the outer periphery of the core cable 2. The toothed cable 1 further comprises a cover layer 4 covering the outer surface of the core cable 2 and the tooth line 3 with a resin continuously. This toothed cable 1 has helical convex portions 41 formed by covering the tooth line 3 with the resin and helical concave portions 42 formed by covering intervals in the tooth line with the resin, and the covered layer 4 is in contact with the core cable 2 and the tooth line 3 and the thickness of the cover layer 4 in the region of the helical concave portions 42 is larger than the thickness of the cover layer 4 in the region of the helical convex portions 41.

Description

technical field [0001] The present invention relates to a durable toothed cable. Background technique [0002] Conventionally, as a mechanism for transmitting the driving force of a gear or the like, there is known a gear rack that transmits the driving force in the axial direction through a rack wound helically on the outer peripheral surface of a core cable made of a metal wire. Toothed cable. The toothed cable passes through the rack, and along the axial direction of the toothed cable, concave parts and convex parts are formed alternately and repeatedly, and the toothed cable is driven along the axial direction by meshing the teeth of the gear with the concave parts. , to transmit the driving force of the driving source such as the gear. As such a toothed cable, for example, a toothed cable 100 is disclosed in Patent Document 1, which is characterized in that, as Figure 4 As shown, the cover 101 extends over both the helical coil winding body 102 and the cable / core 103...
