    [0002] PERFECTED SEPARATOR FOR BEARING ROLLING ELEMENTS
    [0003] This invention concerns an improved separator for rolling elements of bearings.
    [0004]
    [0005] At present it is known to use spacers located between each of the rolling elements located between the raceways of the outer ring and the inner ring of the bearing to maintain a constant distance between them and guide them.
    [0006] Normally, for the assembly, the spacers are introduced one by one into the raceways interspersed with the rolling elements (balls, rollers, needles, cone trunks, etc.). It usually happens that the introduction of the last separator is more expensive, so that it is decided to have a clearance between the rolling elements inside the raceway in order to enable and / or facilitate the introduction of the last separator. Due to this, a correct and effective rotation of the rolling elements does not take place, the rolling elements do not rotate at the same time and an accumulation of the rolling elements can be generated in an area of the raceways. Consequently, undesired forces also appear, thus generating the incorrect operation of the bearing.
    [0007] It is also known a mounting method in which the last two spacers are introduced inclined forming a package with the rolling element for adjustment under pressure in the hole to be covered, which can generate unwanted forces for the correct operation of the bearing by not being treated of a precise fit.
    [0008] The use of separators with different geometries is known as well as the use of separators with different configurations or flexible materials, since they adapt to the space between rolling elements once assembled. However, they are not capable of adjust to all types of bearings and are not versatile in relation to the different gaps to be covered.
    [0009]
    [0010] Faced with this state of the art, the essential object of this invention is an improved separator for rolling elements of bearings; of the spacers used to distance the rolling elements arccircularly and located between the respective raceway of the fixed ring and the movable ring and said spacers having surfaces of complementary geometry of the rolling elements to be used, characterized in that the improved separator is constituted by two parts, and there being adjustable adjustment means between both parts capable of varying the arcolongitudinal dimension of the perfected separator and of which at least one is used in the arc-perimetral assembly of the rolling elements.
    [0011] Thanks to this configuration, it is possible to adjust the spacer to the space remaining between rolling elements obtaining a facility of assembly of this last separator, avoiding unwanted gaps, ensuring the correct positioning of all the rolling elements and therefore achieving a correct and efficient operation of the bearing and greater versatility, being able to cover both small holes and larger holes in a simple way.
    [0012] Another feature of the invention is that the adjustable adjustment means consist of a threaded adjustment element inserted axially between the parts of the improved separator and with a manipulation adjusting nut with the possibility of incorporating guide pins between the two parts of the improved separator. .
    [0013] In this way, when arranging the threaded element of two threaded areas, each with a different thread direction, by applying a twist to the threaded element with a standard key for example or the hand itself, other adjustable adjustment means can be used , it is possible to adjust the separator perfected to the remaining space available between rolling elements, thus avoiding any undesired inaccuracy for the proper functioning of the bearing. Therefore, this arrangement facilitates the assembly of bearings of large dimensions and difficult to access.
    [0014] In the invention, the use of the improved separator is contemplated in the separators called cages incorporating several rolling elements in a cage unit.
    [0015] Thanks to this configuration, the same advantages applied to separators for the separators of this type called cages are obtained.
    [0016] It is also contemplated that the rolling elements may be balls, rollers, needles and other configuration used for rolling elements of bearings.
    [0017] Thus, the perfected separator is applicable to any type of bearing, whether rolling elements, balls, rollers, needles, cone trunks, etc. and thus obtaining an improved separator of great applicability.
    [0018]
    [0019] In order to better understand the nature of the invention, the attached drawings show an industrial embodiment that is purely illustrative and not limiting in its nature.

    [0022] At the top left there is an isometric view, a front view and a sectional view of the perfected separator (3).

    [0045] With reference to the drawings and references listed above, a preferred embodiment of the object of the invention which concerns an improved separator for rolling elements of bearings is illustrated in the attached drawings; of the spacers (2) used to arccircularly distance the rolling elements (4) and located between the respective raceway (5) of the fixed ring (1a) and the mobile ring (1b) and said spacers (2) having geometry surfaces complementary (2a) of the rolling elements (4) to be used in which the improved separator (3) is constituted by two parts (3a and 3b), and there being adjustable adjustment means between both parts (3a and 3b) (6) ) capable of varying the arcolongitudinal dimension of the perfected separator (3) and of which at least one is used in the arc-perimetral assembly of the rolling elements (4).
    [0046] In Figure 1, a bearing (1) formed by a fixed ring (1a) and a mobile ring (1b) is observed in the lower part. In the enlarged detail, the rolling elements (4) are displayed on the raceway (5). Between each rolling element (4) a separator (2) is arranged, one of the separators (2) being an improved separator (3). Thanks to this perfected separator (3) it is possible to adjust the gap that remains between the last rolling element (4).
    [0047] In the upper right part there is represented a perspective view, a front view and a sectional view of the perfected separator (3) in which the improved separator (3) is divided into two parts (3a and 3b) and the adjustment means adjustable elements (6) consist of a threaded adjustment element (7) inserted axially between the parts (3a and 3b) of the improved separator (3) and with a manipulation adjusting nut (7b) with the possibility of incorporating guide pins ( 8) between the two parts (3a and 3b) of the perfected separator (3).
    [0048] In this way, the threaded adjustment element (7) has two threaded areas, each with a different thread direction, so that when turning the adjusting threaded element (7) both parts (3a and 3b) of the perfected separator (3) move relative to one another. The threaded adjustment element (7) has a central area from which to apply the rotation, for example by means of a standard key. To ensure that the parts (3a and 3b) of the perfected separator (3) separate and do not rotate, both parts (3a and 3b) are guided one with respect to the other by means of at least two guide pins (8).
    [0049] It is also observed that the perfected separator (3) has surfaces of complementary geometry (2a) of the rolling elements (4). In this way, the perfected separator (3) is perfectly adapted to the rolling elements (4) when performing the assembly operation, allowing an easy insertion.
    [0050] In figures 2a, 2b and 2c there is another embodiment of the improved separator (3) in which the adjustable adjustment means (6) consist of a threaded shaft (9) integral with one of the parts (3a) of the improved separator ( 3) and a threaded adjustment hole (10) in the other part (3b) of the improved separator (3). Thus, one of the parts (3a) of the perfected separator (3) is integral with a threaded shaft (9) in such a way that when one part (3a) rotates with respect to the other part (3b) of the improved separator (3) increases or decreases the separation between both parts (3a and 3b) of the perfected separator (3), depending on the needs required in each situation.
    [0051] In Figures 3a, 3b and 3c, the improved separator (3) is shown in another embodiment in which the adjustable adjusting means (6) consist of a spring (11) located between the two parts (3a and 3b) of the perfected separator. (3). In this way, the spring (11) is compressed when the improved separator (3) is inserted in the raceway (5) and decompressed to absorb the slack that may exist.
    [0052] In figures 4a, 4b and 4c there is another embodiment of the improved separator (3) in which the adjustable adjustment means (6) consist of a cavity (12) between the two parts (3a and 3b) of the improved separator (3). ) capable of housing a fluid and a pressure adjusting screw (13).
    [0053] Thus, the cavity (12) can be enlarged or reduced depending on the separation between both parts (3a and 3b) of the improved separator (3). The cavity (12) is filled with a fluid and a predetermined pressure is applied to eliminate possible play in the bearing (1). To maintain the pressure or perform the precise adjustment, a pressure adjusting screw (13) is provided which causes the cavity (12) to behave at the beginning of the hydraulic press.
    [0054] In figures 5a, 5b and 5c there is another embodiment of the improved separator (3) in which the adjustable adjustment means (6) consist of a cavity (12) between the two parts (3a and 3b) of the improved separator (3). ) formed by metal elastic plates (14). By this configuration, the cavity (12) can be enlarged or reduced depending on the separation between the two parts (3a and 3b) of the improved separator (3). The cavity (12) is filled with a fluid and a predetermined pressure is applied to eliminate possible play in the bearing (1). The periphery of the cavity (12) is formed by metal elastic plates (14) to block the improved separator (3) in its desired final position. Once the blocking operation has been performed, the fluid can be completely removed.
    [0055] In figures 6a, 6b, 6c, 7a, 7b and 7c another embodiment of the improved separator (3) is observed for the case that the rolling elements (4) are treated with rollers, whether crossed or not, since the invention It is applicable to several types of rolling elements (4) given its versatility.
    [0056] Figure 8 shows the use of the improved separator (3) in the separators (2) called cages (15) that they incorporate several rolling elements (4) in a cage unit, and can also be applied in these executions.
    [0057] Finally, it is also provided that the rolling elements (4) can be balls, rollers, needles and any other configuration used for rolling elements (4) of bearings (1).
    [0058] The essentiality of this invention does not alter variations in materials, form, size and arrangement of the component elements, described in a non-limiting manner, this being sufficient
    [0059] 10 to proceed to its reproduction by an expert.
