Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of milling train combination bearing.
Background technique
At present, multiple row circular cone or roller bearing is generally adopted in milling train industry.Be characterized in that bearing capacity is stronger.But its shortcoming is: 1) install inconvenience, difficult in maintenance.Higher to the technical requirements of installation personnel, cause waste man-hour.2) pretightening force and play adjustment difficulty.
Model utility content
The purpose of this utility model is exactly provide a kind of convenient for installation and maintenance, play to adjust milling train combination bearing easily to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of milling train combination bearing, it is characterized in that, comprise biserial conical bearing, seal ring, back-up ring and bearing support, described biserial conical bearing external diameter is directly inserted on bearing support, described back-up ring is located between biserial conical bearing and bearing support, for location and adjustment bearing clearance, between the inner ring that described seal ring is located at biserial conical bearing and outer ring.
Described biserial conical bearing comprises common outer ring, two rolling elements and two inner rings, and each inner ring is connected with common outer ring by corresponding rolling element.
Described rolling element is equipped with retainer.
Described seal ring is located between common outer ring flange and inner ring rib.
Described bearing support is threaded hole, after in biserial conical bearing embedded axle bearing, after inserting tapped hole, biserial conical bearing and bearing support is loaded seat in the plane in the lump by bolt.
Described bearing inner race end face is provided with oil hole.
Described biserial conical bearing is TDO type double-row conical bearing.
Compared with prior art, the utility model has the following advantages:
1, owing to have employed a set of TDO type double-row conical bearing, such an arrangement provides larger bearing effective span;
2, owing to adopting bearing and seat Combination Design, seat is threaded hole, is very easy to and installs location;
3, owing to adopting circlip location, regulated pretension and the play of bearing by it, thus ensure that bearing works under the play condition of the best, to increase the service life;
4, owing to adopting the design of both sides sealing circle, can effectively prevent introduced contaminants from invading.
5, described combination bearing, inner ring end face, also with oilhole, facilitates oiling.
