CABLE MACHINE

Abstract

A machine for manufacturing cables includes a winch that includes a tube, which includes at least a pulley, a reducer and an input shaft to the reducer in its interior. A system for attaching the reducer includes two concentric bearings. An outer bearing is attached to the reducer and the tube, and an inner bearing is attached to the pulley and outer bearing, such that the pulley is supported by the inner bearing and by bearings of the input shaft of the reducer.

Claims

1. A machine for manufacturing cables comprising a winch, which comprises a tube, wherein the machine, in an interior of the tube, further comprises: a pulley, a reducer, an input shaft to the reducer, a system for attaching the reducer wherein: the system for attaching the reducer comprises an outer bearing and an inner bearing which are concentric each other, the outer bearing is attached to the reducer and a structure that attaches the outer bearing to the tube, the inner bearing is attached to the pulley and to the structure, and the pulley is supported by said inner bearing and by bearings of said input shaft of the reducer.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To aid understanding, an explanatory yet non-limiting drawing is included of an embodiment of the machine according to the invention.

[0020] FIG. 1 is a cross-sectional view of a detail of the upper portion of a winch of a machine for manufacturing cables according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The figure shows the upper portion of an upper section of the tube -1- of a winch -20- according to the present invention.

[0022] In said figure, two bearings -2-, -3- are shown which are mutually concentric. In particular, both bearings are ball bearings. The outer bearing -2- is attached, by the outer face thereof, to the reducer -10- and, by the inner face thereof, to the inner face of the tube -1-.

[0023] In turn, the inner bearing -3- is attached to the pulley -11- by the inner face thereof and to the outer bearing -2- by the outer face of the inner bearing -3-. In particular, in the example, the inner bearing is attached to the structure -14- that attaches the outer bearing -2- to the tube -1-. According to another aspect, the inner bearing -3- is attached to the inner face of the outer bearing -2-.

[0024] As shown, both bearings -2-, -3- are in different planes. More specifically, the inner bearing -3- is raised with respect to the outer bearing -2-.

[0025] As shown, the pulley -11- is held on the inner bearing -3- by means of a corresponding structure and on the bearings -13- of the input shaft -12- of the reducer -10-.

[0026] As shown in the figures, the outer and inner bearings, the pulley and the reducer are connected according to the specifications indicated above, either by means of direct abutment or by means of structural components of which the purpose is to carry out the assigned attaching function. Said structures are connected by abutment, welding and/or screwing, as shown in the figures.

[0027] In the present invention, when it is stated that a bearing is attached to two components, this means that each of said components is connected to one of the parts of the bearing that are in relative movement (such as the faces of a ball bearing).

[0028] Although the invention has been set out and described with reference to embodiments thereof, it should be understood that these do not limit the invention, and that it is possible to alter many structural or other details that may prove obvious to persons skilled in the art after interpreting the subject matter disclosed in the present description, claims and drawings. Therefore, the scope of the present invention includes any variant or equivalent that could be considered covered by the broadest range of the following claims.
