Between, it is respectively corresponded on the inner wall of bearing outer ring and the outer wall of bearing inner race and is provided with the conical surface that two circles are moved for cylindrical roller,
It is biased to bearing outer ring, and the axis and cylinder roller bearing of all cylindrical rollers in the one end for keeping two circle cylindrical rollers close to each other
Axis angle be equal；The retainer offers a circle groove, two guarantors respectively in the both ends of the surface of cylindrical roller axial direction
It holds and is placed with multiple balls that can be rolled along groove, the outer wall of bearing inner race between the groove in frame both ends of the surface close to each other
On offer the groove that the end face that two circles are located remotely from each other with two retainers respectively is oppositely arranged, what two retainers were located remotely from each other
Also be placed with multiple balls between groove in both ends of the surface and respectively opposite bearing inner race groove, the reeded axis of institute with
The axis of cylinder roller bearing is overlapped, and is set ball by opposite two grooves cooperation card and fallen off to avoid ball.
Preferably, the big end of the two circle conical surfaces of bearing outer ring inner wall overlaps, the two circle conical surfaces of bearing inner race outer wall
Big end also overlaps, and the big end of all conical surfaces is respectively positioned on medium position of the cylinder roller bearing along its axial length.
Preferably, the card slot that cylindrical roller both ends of the surface are set for card is offered on the two circle conical surfaces of bearing outer ring inner wall.
Preferably, the position that the groove card of bearing inner race outer wall sets ball is radially not less than ball along cylinder roller bearing
The centre of sphere.
Preferably, the fluted contact angle between ball no more than 90 °.
Preferably, the diameter of the ball is not more than the thickness of retainer.
Preferably, the width that the retainer is located at cylindrical roller two side portions is equal.
According to the above technical scheme, the beneficial effects of the utility model are:
A kind of Biserial cylindrical roller bearing provided by the utility model, by ball instead of card slot in the prior art to circle
The restriction effect of column roller turned position optimizes so only needing to process less card slot on bearing inner race and bearing outer ring
Biserial cylindrical roller bearing structure, reduces the workload in bearing outer ring and bearing inner race process；And two rows circle
It also is provided with ball between the retainer of column roller, so that two retainers is cooperated Forced rotation, it will be able to make two rows of circles
Column roller matching coordinative and Forced rotation, compared with two row cylinder rollers are separately mounted in respective card slot in the prior art,
It is able to ascend the bearing capacity of Biserial cylindrical roller bearing, reduces the abrasion that Biserial cylindrical roller bearing occurs during the work time
To promote bearing life, meet the actual use demand of Biserial cylindrical roller bearing.
