Abstract
The utility model discloses an integral crossed roller bearing. The crossed roller bearing comprises an inner race and an outer race which are concentric, wherein a raceway is formed between the outer race and the inner race; a plurality of cylindrical rollers are uniformly assembled in the raceway and comprise axial rollers, which are axially arranged on the side surface of a cylinder, and radial rollers, which are radially arranged on the side surface of the cylinder; the axial rollers and the radial rollers are alternatively arranged in the raceway along the circumference; and a separator is arranged between each two adjacent rollers. A plurality of mounting holes are uniformly distributed in the circumferential direction of the outer race; and arc grooves are formed in the two ends of each separator and matched with the adjacent cylindrical rollers. A slewing bearing of a spandex winding machine is designed to be of an integral structure, the processing difficulty of related parts can be lowered, the supporting rigidity is improved, and the crossed roller bearing is more convenient to dismantle; and the axial rollers and the radial rollers are alternatively arranged in the raceway along the circumferential direction, so that the rotating accuracy of a rotating body is effectively ensured.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of integrated type criss-crossing roller bearing.
Background technique
The spandex up-coiler has obtained using widely as a kind of highi degree of accuracy spandex fiber equipment now.Existing spandex up-coiler pivoting support bearing structure, what adopt is the mode that a plurality of part assemblings form pivoting support bearing, as bearing inner race, bearing outer ring, all rolling elements, holder all assemble as part with solid of rotation, realize rotatablely moving of solid of rotation.The correlated parts difficulty of processing is big, and the assembling link is many, complex structure, and the running accuracy of solid of rotation is not easy to guarantee that matching gap can't be adjusted.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, propose a kind of simple in structure, the integrated type criss-crossing roller bearing of being convenient to mount and dismount.
The technical problems to be solved in the utility model is to realize by the following technical programs, a kind of integrated type criss-crossing roller bearing, the outer ring and the inner ring that comprise concentric setting, between outer ring and inner ring, be provided with raceway, be characterized in: several equally distributed cylindrical rollers are installed in the described raceway, cylindrical roller comprises the radial roller that axial axial roller that is provided with of column side face and column side face radially are provided with, axially roller and radial roller circumferentially are arranged alternately in raceway, are provided with divider between adjacent rollers.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with the mounting hole that several evenly are provided with in the outer ring on circumferentially.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the two ends of described divider are equipped with and are adjacent the arc groove that cylindrical roller cooperates.
Compared with prior art, the utility model is designed to overall structure with spandex up-coiler pivoting support bearing, has reduced the difficulty of processing of correlated parts, has improved the rigidity intensity that supports, and makes that dismounting is convenient; The axial roller and the radial roller that circumferentially are arranged in the raceway are arranged alternately, have effectively guaranteed the running accuracy of solid of rotation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of integrated type criss-crossing roller bearing, the outer ring 1 and the inner ring 2 that comprise concentric setting, between outer ring 1 and inner ring 2, be provided with raceway, several equally distributed cylindrical rollers are installed in the described raceway, cylindrical roller comprises the radial roller 5 that axial axial roller 3 that is provided with of column side face and column side face radially are provided with, axially roller 3 circumferentially is arranged alternately in raceway with radial roller 5, is provided with divider 4 between adjacent rollers.
Upwards be provided with the mounting hole 6 that several evenly are provided with 1 week in the outer ring; The two ends of described divider 4 are equipped with and are adjacent the arc groove that cylindrical roller cooperates.The described casing of mounting hole 6 by sunk screw and spandex up-coiler that is arranged on the outer ring 1 forms end face and is connected, and inner ring 2 external cylindrical surfaces direct and solid of rotation assemble, and makes simple in structurely, dismantles convenient.Be provided with divider 4 between axial roller 3 and radial roller 5, be provided with the arc groove that cooperates with axial roller 3 at an end of divider 4, the other end is provided with the arc groove that cooperates with radial roller 5.
Claims (3)
