Definitions
- the present invention relates to a modular rolling group, which allows to establish at will the number of bearings that participate in it, according to the specific needs of each case, and with the essential purpose of achieving a multiplier, amplitude effect variable depending on the number of bearings participating in the group.
- a bearing consists of a bearing formed by two coaxial cylinders between which a crown of balls or rollers that can rotate freely is inserted, so that the corresponding element, such as an axis, is fixed to the internal cylinder, while that the element to be rotated on said axis is fixed to the external cylinder, such as a pinion, a crown, a plate, etc.
- the modular rolling group proposed by the invention solves in a fully satisfactory manner the aforementioned problem, in the two aspects mentioned, so that said modular group allows to obtain a multiplier effect within the group itself, between the first and the last of the bearings that participate in it, which causes the speed differential to be divided between all of them, and that each one rotates at a considerably lower speed, and on the other hand the different bearings can be fixed to each other so that they rotate all of them at the same speed and simultaneously, enhancing the mechanical resistance of the group as a whole.
- a plurality of bearings participate, in varying numbers, each of which is axially extended in a cylindrical neck coupling to the bearing immediately adjacent, for which purpose the external diameter of said neck corresponds to the inner diameter of the inner race of the adjacent bearing, to which it must be attached and fixed.
- said cylindrical neck is integral with a single-piece character to the external raceway of the bearing to which it belongs, in which case the first of the aforementioned effects will be achieved, that is, the multiplier effect , or that said cylindrical neck is integral with the internal raceway of the bearing to which it belongs, in which case the bearing group will act as a single bearing of greater axial dimension.
- Said neck may be provided with an external thread for fixing to the inner race of the adjacent bearing, threaded in correspondence, or the different modules or bearings can be fixed together by simple pressure coupling, in the same way as the External raceway can also be threaded to facilitate the assembly of any of the usual accessories such as pinions, plates, crowns, etc., or be smooth for the coupling of these pressurized elements.
- said neck is physically independent of the two bearings or bearings to be related, so that It has two coaxial and substantially different diameter necks, the one with the smallest diameter intended to be engaged within a bearing, and the one with the largest diameter intended to be externally coupled to another bearing, either interchangeably by means of pressure, thread or any other system.
- each bearing the outer race is single-piece connected to the axial neck, it will result that when said axial neck is coupled to a second bearing, the inner race of the latter will rotate simultaneously as the outer race of the first , thus achieving a substantial demultiplication, which is enhanced as the number of bearings that participate in the modular group is increased, such that between the inner race corresponding to the first bearing and the outer race to the latter, a demultiplication can be achieved as large as desired.
- Figure L- Shows, according to a schematic perspective representation, a bearing participating in the modular rolling group that is the object of the present invention.
- Figure 2. Shows a diametral section thereof bearing of the previous figure.
- Figure 3. Shows a group of four bearings like the one in Figure 1 duly inter-coupled coaxially.
- Figure 4. It shows a detail in diametral section of the bushing or double neck that allows coaxial coupling and with a multiplier effect between two conventional bearings.
- a plurality of bearings (1) participate in the modular rolling group, each of which is constituted by the two classic cylinders, or tracks of rolling, an internal (2) and an external (3) between which the set of balls (4) is established that facilitates the rotating displacement of one track with respect to the other, but with the special feature that the bearing itself (1) extends into a neck (5), preferably provided with an external thread (6) complementary to another thread (7) that internally has the inner race or smaller diameter (2) of the bearing, so that through From this neck (5) several bearings (1) can be interconnected coaxially interconnected, by threading, as shown in Figure 3.
- the neck (5) is feasible to be attached with a single-piece character to the raceway (2) of smaller diameter, so that a bearing of greater mechanical resistance is achieved in the coupling between modules, but fundamentally and in accordance with the representation of the figures, said neck (5) will be connected with a single piece to the external raceway (3), by means of an annular wall (8), as shown in Figure 2, so that said neck (5) acts to the second bearing (1) in an analogous manner, as if it were mounted on the external raceway (3) of the first bearing, and so on, thereby achieving the repeatedly cited multiplier or demultiplier effect, as desired, since the outer race (3) of each bearing with the neck (5) of the bearing is single-handed, when the next bearing (1) is fixed to the latter, the outer race of the first bearing is practically one-piece with the track in terna of the second bearing, through the neck (5) that relates them. In turn, the outer race of the second bearing will be single piece with the inner race of the third bearing, and so on, so that the greater the number of bearings participating in
- bearings (1) participate, that is, manufactured with the aforementioned characteristics that are required for coaxial coupling, but nevertheless the possibility is also foreseen that
- the bearings (1) can be conventional, for which purpose and instead of the neck (5) being monopieza with the own bearing, the participation in the modular group of bushings (9) is foreseen, as the one represented in the figure 4, in which two necks are established, a neck (10) equivalent to the aforementioned neck (5), and with the same purpose of interlocking within the next bearing, and a second neck (11), of considerably larger diameter, intended to be engaged and fixed in turn to the outer raceway (3) of the adjacent bearing.
- the outer surface of the raceways (3) of greater diameter will also be provided with a thread (12) that facilitates the coupling to such bearings or rolling modules of two cogwheels or toothed crowns (13) which, by means of chains (14) transmit the movement to a second axis, which can be of the same or different characteristics, as shown in Figure 5.
