Abstract
The utility model relates to a one-way needle roller bearing with an axial stopping groove, which comprises an inner ring, an outer ring and a retainer which is arranged between the inner ring and the outer ring; the bearing is characterized in that: the axial stopping groove is respectively arranged on the outer diameter of the outer ring and the inner diameter of the inner ring of the bearing, a spring piece is arranged on the inner surface of the outer ring of the bearing, roller pins are evenly arranged in the retainer along the circumferential direction; the bearing has advantages of convenient installation and manufacturing, accurate and appropriate positioning and the like.
Description
Technical field
The utility model relates to unidirectional needle bearing technical field, and especially a kind of tape spool is to the unidirectional needle bearing of locking groove.
Background technique
The installation of existing bearing outer ring is outer circle external diameter and pallet hole interference fit location, thereby dismounting is cumbersome.When magnitude of interference is big, might cause outer ring extrusion-deformation, make the bearing disabler; And magnitude of interference hour, can cause outer ring and hole slide relative to make bearing failure.And on the bearing outer ring external diameter and process an axial retention groove respectively on the inner ring internal diameter, just can avoid the generation of above-mentioned two kinds of problems, accurate positioning, appropriateness is guaranteed the bearing safe handling, using when rotating, axle inner ring or outer ring only at folk prescription to rotation.
The model utility content
In order to overcome the deficiency of existing unidirectional needle bearing, the utility model provides the unidirectional needle bearing of a kind of tape spool to locking groove.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of tape spool comprises bearing inner race and outer ring to the unidirectional needle bearing of locking groove, between inside and outside circle, place retainer, in retainer, along the circumferential direction place needle roller equably, on the bearing outer ring external diameter and the inner ring internal diameter on be respectively equipped with an axial retention groove and, a spring sheet is set on the internal surface of bearing outer ring, the outer ring of axial zone locking groove is installed on the conveying disc to be fixed, and keeps enough moments of torsion.The inner ring of tape spool to locking groove is fixed on the transmission shaft.
The beneficial effects of the utility model are: this tape spool is convenient to install and make to the unidirectional needle bearing of locking groove, simultaneously, this structure friction torque when rotated is little, noise is low, secondly, when need carry out lifting or transmission work, because of bearing can only one-way rotation, can be stable carry, lifting transmission work.

Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in the figure, be respectively equipped with an axial retention groove 6 and 7 on bearing outer ring 1 external diameter He on inner ring 5 internal diameters, in retainer 2, along the circumferential direction place needle roller 3 equably, a spring sheet 4 is set on the internal surface of bearing outer ring 1, tape spool is fixed on the conveying disc to the outer ring 1 of locking groove 6, and keeps enough moments of torsion, and tape spool is fixed on the transmission shaft to the inner ring 5 of locking groove 7, when use rotating, 1 of axle inner ring 5 or outer ring at folk prescription to rotation.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (2)
