Definitions
- the invention relates to a tapered roller bearing with two coaxial bearing rings and a plurality of arranged between the bearing rings, guided in a cage tapered rollers that roll on raceways on the bearing rings, with a board on the large diameter of the inner bearing ring, wherein the cage to form Bags for the tapered rollers consisting of side rings and connecting webs, and on a side ring resilient projections are arranged, which cooperate with the board and bias the cage with the tapered rollers axially against the board.
- the object of the invention is to propose a tapered roller bearing which, according to the state of the art, retains the function of the operatively preloaded tapered rollers for an optimized assembly operation, but which does not have the resulting constraining forces during the bearing operation.
- the invention relates to a tapered roller bearing with two coaxial bearing rings and a plurality of arranged between the bearing rings, guided in a cage tapered rollers which roll on raceways on the bearing rings, with a board on the large diameter of the inner bearing ring, wherein the cage to form Bags for the tapered rollers consisting of side rings and connecting webs, and on a side ring resilient projections are arranged, which cooperate with the board and bias the cage with the tapered rollers axially against the board.
- fewer projections are arranged as pockets on the side-near the side ring.
- the cage is easier to manufacture, especially if it is designed as a plastic injection molded part, since fewer projections are formed.
- the projections are arranged uniformly spaced on the side ring, preferably in the region of the pockets. If the cage has an even number of pockets, the projections may preferably be arranged in the region of every other pocket on the side-near-side ring.
- An advantageous measure to improve the elasticity of the projections and to reduce the friction on the tapered rollers is to form the projections bent towards the board, and tapering in the area of their cooperating with the board ends.
- Another measure to increase the elasticity of the projections and torsionally elastic form the near-board side ring is to provide the near-board side ring in the area between the webs on both sides of the projections with recesses.
- the overall elasticity of the cage can be increased while reducing the friction when the small diameter of the tapered rollers adjacent side ring is formed wavy in the area between the webs and rests with a respective wave crest on the small end face of the associated tapered roller.
- the transmission element may preferably be formed on the cage by at least partially attached, preferably electrically or magnetically acting coating.
- the transmission element is formed on the cage by an at least partially attached electrically or magnetically acting coating on at least one of the projections in this way, in particular, the rotational speeds of the individual components of the rolling bearing, such as the rolling elements, the cage and the inner ring capture and use for condition monitoring of the warehouse during operation.
- FIG. 1 shows an axial partial section through a tapered roller bearing according to the invention with a cage
- FIG. 2 shows a partially radial internal view of the cage in the tapered roller bearing according to FIG. 1.
- the tapered roller bearing 1 consists of an outer bearing ring 2 and an inner bearing ring 3, between which tapered rollers 4 are arranged, which roll on raceways 7, 8 of the bearing rings 2, 3 and are accommodated in a cage.
- the cage consists of two side rings 10, 11 and these side rings connecting webs 12, wherein between each two adjacent webs 12, a pocket 12 for receiving the tapered rollers 4 is formed.
- the tapered rollers 4 are supported with their large diameter end faces 5 on a radially outwardly facing board 9 on the inner bearing ring 3, while the small diameters end faces 6 abut only the bordfernen side ring 11 of the cage.
- the webs 12 are arranged radially outside of the tapered roller axles 23 in order to arrange the tapered rollers 4 as closely as possible to one another and to be able to increase the number of tapered rollers 4 in the bearing.
- radial projections 14 are formed in the form of claws, which engage behind a paragraph 17 on the board 9 of the inner bearing ring 3 axially.
- the voltage applied to the shoulder 17 ends of the projections 14 are provided with Anflambaitch 15 or tapered to keep the contact surface on the shoulder 17 as small as possible, whereby the friction is reduced in this area.
- the projections 14 are bent approximately semicircular towards the radial and axial bearing center and are slender towards their ends provided with the flats 15, whereby their elasticity is increased.
- a further measure for increasing the elasticity of the projections 14 and for increasing the torsional elasticity of the side ring 10 close to the board provides that on both sides of the projections 14 axial recesses 16 are made in the side ring 10 which is close to the board.
- the bordferne side ring 11 is wave-shaped between the webs 12, wherein at the troughs 18, the webs 12 are connected to this side ring 11, while the wave crests 19 abut the roller end faces 6 and press the tapered rollers 4 axially against the board 9.
- the peaks 19 lie with a small, curved surface area at the bordfernen and smaller diameter end faces 6 of the tapered rollers 4, so that here too the friction is reduced.
- protrusions are arranged or formed on the off-board side ring 11, at least one of which is designed as a transmission element 21 to condition-monitor the kinematic conditions of the bearing in cooperation with a sensor, not shown, arranged on a housing for the tapered-roller bearing or the like to enable in operation.
- a comparable transmission element 20 may be arranged, as well as a transmission element 22 on at least one tapered roller 4 or at least one of the projections 14 of the cage.
- the transmission elements are preferably designed as an electrically or magnetically acting coating.
