Description

It is known to manufacture flexible shafts by winding four or more wires onto a core, as well as machines for manufacturing such shafts, consisting of a hollow shaft, perpendicular to the axis of which two mutually perpendicular axes are attached to loose coils with wire, are known. . In the proposed machine, a cone-shaped head is used, inserted at the end of the shaft and equipped with two disks with holes, corresponding to the number of wires to be wound.

In FIG. 1 is a front view of the machine; FIG. 2 is a side view of it; FIG. 3 is a side view of the head, and FIG. 4 is a section to line AB in FIG. 3

The machine (Fig. 1, 2) consists of a hollow shaft 2, into the end of which a cone-shaped head 7 is inserted (Fig. 2, 3, 4), and two mutually perpendicular axes 5 with attached coils b are attached to its axis perpendicularly to its axis. wire In order to ensure uniform tension, the wires coming from the coils are threaded through the holes of the disk 4 mounted on the shaft. Head 7 fixed

at the end of the shaft, has inside a hole, corresponding to the thickness of the core, which passes through the hollow shaft 4 and is used for winding wire onto it. At the cone-shaped end 1 of the head, the disk 3 is fixed, the holes in which correspond to the same in the disk 4. The shaft 2 is fixed in the chuck of a lathe or any other machine having a rotational movement. Through the holes in the spindle of the machine, the shaft 2 and the head 7, a core is passed through which is wound on a freely rotating coil placed against the spindle hole of the machine. When the machine is put into operation, it rotates the device around the core and winds a layer of wire on it, as it coils with some layer resting on the ball end of the head 7, the core is pulled through the device, and the wound part of it is wound on the coil and driven by the suspension unit or: in some other way. The first layer of wire wound on the core can be wound on the next layer.

in the opposite direction, etc., and thus obtain a flexible shaft consisting of any number of layers of wire.

The subject of the patent.

A machine for the manufacture of flexible shafts, which simultaneously winding four wires onto a core and consisting of a hollow shaft, perpendicular to the axis of which two mutually perpendicular axes are attached to the coils freely mounted on them with a wire that is characterized by the use of the end of the shaft 2 of the cone-shaped head 7 with wire guides discs 3 and 4, each of which has four holes, respectively, the number of wires to be wound.
