Definitions
- the invention refers to a vibration isolation device in agricultural machines that contributes, to the function to which it is intended, advantages and characteristics, which will be described in detail below, which they represent a remarkable improvement of the current state of the art.
- the object of the invention focuses on vibration isolation device based on rubber elements applicable to agricultural or similar work machines incorporating rollers, whether or not provided with work tools, attached to them by supporting structures, the which, unlike existing systems, provides such isolation in all directions to ensure, not only the insulation of the supporting structure but also that the vibratory charges do not destroy the insulating elements themselves, for which it is configured based of multiple rubber elements incorporated radially and with a certain inclination on both crowns on both sides of the roller, being placed as a union between it and the supporting structure.
- the field of application of the present invention is part of the industry sector dedicated to the manufacture of accessories for agricultural machines and vehicles, focusing specifically on the field of vibration isolation systems.
- These machines usually incorporate cutting / work tools on circular rollers. These cutting tools are arranged longitudinally or at an angle to the axis and generate strong loads during their rotation on the ground.
- the systems presently present do not provide a blunt solution to the problem, because they incorporate an insulation, focusing on the reduction of vibration mainly in a single direction of the rotating element and neglecting or taking into account the loads to a small extent vibratory in the other directions of space.
- These systems therefore focus on the insulation in the vertical direction (perpendicular to the ground plane) whose main receiver is the supporting structure.
- they incorporate rubber elements arranged in the absorption position in a main direction and leaving the rest of the components to the absorption capacity of the elastic support used in each case.
- the roller during its rotation, at the moment in which each cutting tool interacts with the ground, generates radial loads that will decompose in different positions of the X and Y axis, so that the structure or arm that pulls the roller It is in a continuous situation of "draft” and "thrust” on the horizontal axis and at the same time traction and compression on the vertical axis.
- the insulating elements of these vibrations should cover both directions and with the full range of angles of the possible loads, the objective of the present invention being the development of a new type of vibration isolation system that covers the whole range of possibilities .
- the vibration isolation device in agricultural machines that the invention proposes is configured as a novelty within its field of application, since, being the characterizing details that make it possible and that distinguish it conveniently included in the accompanying final claims to the present description.
- a vibration isolation device in agricultural machines that, in a novel way, performs such isolation in all directions to ensure, not only the insulation of the supporting structure but also that vibratory charges do not destroy the insulating elements themselves due to premature fatigue due to a resonance input.
- the device is configured essentially from a crown incorporated on each side of the roller, so that both are opposed, and each have several rubber insulating elements, preferably five, arranged radially around the same.
- said rubber elements are positioned, each of them, between two flanges, one of which, which we will call inside, is anchored to the rotating bearing support of the machine's roller axis, and the other, which we will call Outside, it is attached to the bearing structure of the machine roller.
- the roller is, therefore, totally subject to the supporting structure only by the insulating elements resulting in a flexible support and with six degrees of freedom.
- the rubber elements used have good vibration isolation and low mechanical loads in the transverse position to the fixing direction and less insulation and high mechanical loads in the longitudinal direction to the fixing with the supporting structure.
- the isolation device provides great mechanical resistance. But low isolation. And, as we modify the angle of arrangement and the rubber elements with respect to the axis of rotation and they are oriented more parallel to the longitudinal axis of the roller, the isolation of vibrations increases greatly and the resistance to mechanical loads decreases.
- the solution provided by the device allows, advantageously, to adjust the operating angles of the rubber elements according to the type of terrain, hard, soft ... etc ... in which the machine to which it is to be worked incorporates by means of the angle and the tightening of the outer flanges that hold the rubber elements on the inner flanges.
- the structural configuration of the device allows to play with the hardnesses and the dimensioning of the flexible rubber elements, adjusting them in the best possible way to the conditions of each case.
- the described vibration isolation device in agricultural machines therefore, represents an innovation of structural and constitutive characteristics unknown until now, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
- Figure number 1 Shows a partial perspective view of the roller bearing structure of an agricultural machine to which an example of the vibration isolation device, object of the invention, has been incorporated, appreciating the parts and elements that it includes, as well as its configuration and arrangement.
- Figure number 2. It shows an almost frontal view of the roller and its supporting structure, where the interposition of the rubber element between the two flanges and forming the isolation device, according to the invention, is appreciated.
- Figure number 3. Shows a side view of the roller and the supporting structure of the machine with the device of the invention.
- Figure number 4.- It shows a totally frontal elevation view of the roller, showing the inclination of the rubber elements it incorporates protruding at each end.
- the device (1) in question which is designed to be incorporated in an agricultural machine or the like, of which they have at least one roller (2) coupled thereto through a supporting structure (3) to which it is attached at its ends, and may or may not be provided with blades (4) or other work tools on its surface, the device (1) serving as a means of insulating vibration produced when the roller (2) is dragged on the ground in a transverse direction to the longitudinal axis (5) of rotation of said roller (2), it is essentially configured from two crowns (6) which are incorporated, opposed, a at each end of the roller (2), between the bearing support of its shaft (5) and the corresponding end of the bearing structure (3), each having several rubber insulating elements (7) radially distributed around it and fixed, between respective pairs of flanges (8, 9) that fasten them, respectively, to said bearing of the roller shaft (5) bearing (2) and to the end of the bearing structure (3), so that they constitute a connecting link flexible between both elements.
- the rubber insulating elements (7) is configured by a flat piece or disk, and each one is held, by way of a sandwich, between an inner flange (8), which is anchored to the bearing support itself of rotation of the shaft (5) of the roller (2), and an outer flange (9) that is attached to the end of the supporting structure (3).
- these flanges (8, 9) have an inclined arrangement with respect to the crown plane (6) which, in turn, adopt the rubber insulating elements (7), which inclination, being able to be constant or not in all of them , it is variable in each case depending on the needs of use of the machine, since, to greater coplanarity with respect to the axis (5) of rotation of the roller (2), greater isolation of vibrations but less mechanical resistance and, to greater perpendicularity with respect to said axis (5), lower vibration isolation but greater mechanical resistance.
- the flanges, at least the outer ones (9) can be movable, for example by screwing, to allow a slight modification of their inclination and, consequently, of the rubber insulating elements (7).
- each crown (6) incorporates five rubber insulating elements (7), evenly distributed around it, although this should not be taken as a limitation, since the essential of the device is the fact comprising, at each end of the roller (2), and fixed with variable inclination between the shaft bearing support (5) and the corresponding end of the bearing structure (3), several insulating elements (7) of rubber distributed radially to said shaft (5), so that they constitute a flexible link between both elements.
