Abstract
The utility model discloses a cylindrical roller bearing with filling holes in end surfaces. The cylindrical roller bearing with the filling holes in the end surfaces comprises an inner ring and an outer ring, wherein an annular rectangular groove is formed in the outside surface of the inner ring; an annular rectangular groove which is in the same with the groove in the inner ring in size and opposite with the groove in direction in the inner ring is formed in the inside surface of the outer ring; after the outer ring and the inner ring are sleeved and are aligned, the two grooves are closed into an annular rectangular raceway; a plurality of cylindrical rollers are arranged in the annular rectangular raceway in a filling manner; an inner gap and an outer gap are respectively formed in the combined end surfaces of the inner ring and the outer ring; a roller filling hole is formed by the inner gap and the outer gap by taking the midpoint of a combination seam of the inner ring and the outer ring as the center; after the rollers are arranged in the roller filling hole in the filling manner, the filling holes are respectively blocked by two locking blocks. The cylindrical roller bearing with the filling holes in the end surfaces is reasonable and reliable in structure, and wide in application range, can be applied to a large roller bearing, and also can be applied to a small roller bearing; the two locking blocks are not separated from the respective end surface under any operating conditions and are not required to be fastened by bolts or penetration pins; the simple and neat appearance, meeting the aestheticism, of the roller bearing is ensured.
Description
Technical field
The utility model relates to engineering goods part field, and specifically a kind of end face arranges the roller bearing of filling hole.
Background technique
Bearing is the vitals of supporting axle, its effect be retainer shaft working position, ensure the running accuracy of axle and reduce the friction factor of axle.Bearing is divided into sliding bearing and the large class of rolling bearing two by friction type difference.Rolling bearing is pressed the kind difference of rolling element, is divided into ball bearing (rolling element is steel ball) and roller bearing (rolling element is roller).Roller bearing is pressed roller kind, is divided into again: roller bearing, tapered roller bearing, needle bearing etc.But existing roller bearing or can only be applied to larger roller bearing, or can only be applied to less roller bearing, application area is single.
Model utility content
The purpose of this utility model is to provide a kind of end face and arranges the roller bearing of filling hole, can be applicable to larger roller bearing, also can be applicable to less roller bearing.
The technical solution of the utility model is as follows:
A kind of end face arranges the roller bearing of filling hole, include inside and outside circle, it is characterized in that: the outer side surface of described inner ring is provided with ring-type rectangular recess, the inner side surface of described outer ring is provided with ring-type rectangular recess identical with inner ring groove size but opposite direction, described outer ring and inner ring be nested and neat after, described two grooves are merged into ring-type rectangle raceway, in described ring-type rectangle raceway, are filled with several cylindrical rollers; On an end face of described inside and outside circle combination, be respectively equipped with inside and outside breach, described inside and outside breach forms roller filling hole centered by the mid point of the bonding crack of described inside and outside circle, described roller filling hole completes after roller filling, respectively by two lock dog shutoff.
Described end face arranges the roller bearing of filling hole, it is characterized in that: two described lock dogs are identical with the shape of the inside and outside breach of composition roller filling hole respectively, and the processing dimension of two lock dogs respectively correspondence be greater than the about 0.01mm of inside and outside breach.
Described end face arranges the roller bearing of filling hole, it is characterized in that: described roller filling hole be shaped as circle, rectangle, two arch, internal moment outer ring or interior arch outer ring.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, reliable, can be applicable to larger roller bearing, also can be applicable to less roller bearing, applied range, under two any operational conditions of lock dog, do not separate with end face separately, without with screw or wear and lock admittedly, ensure that roller bearing meets the profile of aesthetic brevity and lucidity.
