Problems solved by technology
Due to the two-way guidance, the rings no longer deform differently from each other in the radial direction, thereby increasing the strength of the entire structure, wherein the bearing ring cannot be moved locally away from the other ring in the radial direction
[0008] However, the disadvantage is that, especially in the radial direction, considerable installation space is required for the arrangement of the lobed rings

Embodiment Construction
[0025] figure 1 shows a cylindrical roller bearing according to the invention for absorbing axial and radial forces, which is used in particular as a blade adjustment bearing on a wind turbine for connecting individual blades to a rotor so as to be able to rotate around The blades rotate longitudinally.
[0026] The cylindrical roller bearing has a first bearing ring 1 and a second bearing ring 2 which are arranged coaxially about an axis of rotation extending in the axial direction x.
[0027] exist figure 1 In the exemplary embodiment, the first bearing ring 1 forms an inner ring, and the second bearing ring 2 forms an outer ring, wherein the reverse configuration of the first bearing ring 1 and the second bearing ring 2 is also possible without any limitation .
[0028] The second bearing ring 2 has a groove 3 that is open in the radial direction. exist figure 1 In the illustrated embodiment, the second bearing ring 2 forms the outer ring, the groove 3 opening in an in...

The invention relates to a cylindrical roller bearing for absorbing axial and radial forces, the cylindrical roller bearing comprising a first bearing ring and a second bearing ring, which are arranged concentrically about an axis of rotation extending in the axial direction. The second bearing ring has a groove, which is open in a radial direction and in which a projection of the first bearing ring engages, a first radial bearing row and two axial bearing rows spaced in the axial direction are arranged between the projection and the groove, the first radial bearing row supports the first bearing ring against the second bearing ring in a first radial direction, and a second radial bearing row is provided, which supports the first bearing ring against the second bearing ring in a second radial direction that is opposite to the first radial direction. According to the invention, the first bearing ring is divided in the axial direction into at least one first ring part having the projection and one second ring part, and the second radial bearing row is arranged between the second ring part and the second bearing ring at an axial distance from the projection.
Description
[0001] This application is a divisional application of the Chinese patent application with the application number 201480005788.3, the application date is January 06, 2014, and the invention name is "cylindrical roller bearing". technical field [0002] The invention relates to a cylindrical roller bearing for absorbing axial and radial forces, comprising a first bearing ring and a second bearing ring arranged coaxially around a rotating shaft extending in the axial direction, wherein the second bearing ring have grooves open in the radial direction and engaged with the lobes of the first bearing ring, wherein between the lobes and the grooves a first radial bearing row is arranged and spaced apart from each other in the axial direction of two axial bearing rows, wherein the first radial bearing row supports the first bearing ring against the second bearing ring in the first radial direction, and wherein a second bearing row is provided which supports the second bearing ring i...
