Abstract

The invention solves the problem of dependently controlled rotation of the intermediate ring of a relatively rotating three-ring rolling bearing in a simple mechanical way. The essence of the invention is a steering rolling bearing, from which the cage is firmly connected to the intermediate ring of the three-ring rolling bearing, which has an inner cage firmly connected to the inner ring of the steering rolling bearing, while the outer ring of the three-ring rolling bearing and the steering rolling bearing form a single unit. The invention can be used in mechanical engineering wherever a relatively rotating three-ring rolling bearing with an uncontrolled intermediate ring is unreliable in operation or a relatively rotating three-ring rolling bearing with an independently controlled intermediate ring is unusable for various reasons, especially in the textile industry and in mechanical engineering in general.

BACKGROUND OF THE INVENTION The present invention relates to a relative rotating tpo-ring roller bearing s-o dependent on the intermediate ring. In the construction of the various str-Q-jets for rolling the mass with minimal friction, a rolling bearing is important, in which rolling bodies separated by a separating section are rolled away in the groove during operation between the outer and inner bearing rings. The roller bearing is structurally different from each other not only according to the direction of load-bearing and radially-axially, according to the shape of the rolling bodies, for example balls, rollers or rollers. and cones, according to the number of rolling-contact rows and contact with bearing rings, but also the cooling and lubrication system, and the purpose for which they are to be used. However, the common feature of all rolling bearings is their dimension expressed by basic dynamic load capacity and turning frequency. as parameters affecting the durability of a rolling bearing In order to increase the performance of the apparatus, the above-mentioned basic parameters of the rolling bearing are further increased, but in contrast to the fact that by appropriate choice of the material and by increasing the size of a certain rolling bearing, its basic dynamic load increases and the limiting frequency of rotation decreases. vice versa. However, the rolling frequency of the rolling bearing is one of the technical paraimeters, the increase in which only the difference from the basic dynamic load capacity limits and leads to a precise miniature, special cooling and grease bearing. To achieve maximum limit values for the rolling bearing speed without requiring even more sophisticated cooling and lubrication, better material coverage means using the principle of relative rotation based on the inner bearing ring rotors when designing a new high-speed roller bearing. which has, in the same sense, a slower rotating intermediate ring of the three-ring rolling bearing, the same as if it were standing. A relative rotating rolling bearing formed by a three-ring rolling bearing with two radial bodies separated by an intermediate ring is known in practice as an uncontrolled intermediate ring or an independently controlled intermediate ring. The limiting frequency of rotation of the relative rotating three-ring roller bearing with the uncontrolled intermediate ring is indeterminate, depending on the instantaneous ratio of the passive-opposed two-part three-spherical roller bearing, since the rolling bearing is unreliable in operation . A relative rotating three-ring roller bearing with an independently controlled intermediate ring which is adapted to control its drive, for example, by an electric motor, has a limited rotational frequency of a certain but starting installation of an independent rotary motion source. Attempts to form a relative rotating three-ring roller bearing with an intermediate ring driven in dependence on the rotational speed of the rotating shaft have led to the transmission overhang and this practice has not penetrated. To eliminate the shortcomings of the relative rotating triple-ring bearings mentioned above, it is also desirable to produce a relatively rotating three-ring rolling bearing, which, by a simple mechanical means, utilizes its own rotation to drive the drive of its intermediate ring.

Such a relative rotating three-ring bearing, which uses its own acudite friction planetary gear to control the drive ring, is a rotatable three-spherical roller bearing with a dependently controlled intermediate ring according to the invention, the essence of which is a control rolling bearing with which the cage is fixed a connecting ring of a three-ring ball bearing, which has a fixed inner cage with the inner ring of the control roller bearing, the outer ring of the three-ring rolling bearing and the roller bearing being integral.

The relative rotating three-ring rolling bearing with dependent steered intermediate ring is simple to manufacture, and in practice practicable, where the relative rotating three-spoke rolling bearing with uncontrolled or independently controlled intermediate ring is currently disadvantaged. especially in the textile industry and in engineering at all.

The device according to the invention is evident from the accompanying drawing, in which Fig. 1 shows a relative rotating three-ring rolling bearing dependently controlled intermediate ring in a front view, and Fig. 2 is a side elevation of said bearing according to line A-A of Fig. 1.

As a whole, the outer ring 3 (FIG. 2) of the three-ring rolling bearing 1 and the control rolling bearing 2, the copper ring 6 and the inner ring 4 of the three-ring rolling bearing 1 and the inner ring 8 of the rolling-contact bearing 2 are made of solid materials, such as steel and grooved grinding bodies for rolling in them, which, for example, are made of steel and can be cones, rollers or barrels in addition to the balls. The inner cage 5 and the outer cage 7 of the three-ring rolling bearing 1 -a cage 9 of the control-bearing bearing 2, which are separated by three separate ring-shaped and one-sided individual supporting bodies, are of solid and For example, in the case of a material such as, for example, a bronze or a binder, the nonwoven material may be, for example, polyamide or fabric. The three-ring antifriction bearing 1 and the antifriction bearing 2 are coupled together in a nipple-like manner such that the inner cage 5 of the three-ring rolling bearing 1 is axially fixedly connected to the inner ring 8 of the rolling-contact bearing 2,
