Abstract
The utility model relates to a rotation supporting bearing, in particular relates to a double-column angular contact cylindrical roller rotation supporting bearing with independent frame type isolation rings, and belongs to the field of bearings. The double-column angular contact cylindrical roller rotation supporting bearing comprises an outer ring, an inner ring, rollers and retainers, wherein a mounting hole is formed in the outer ring; a roller stopping block is arranged in the mounting hole; the outer ring is fixed with the roller stopping block through a conical pin; an independent frame type isolation ring structure is adopted; the contact surfaces of the two independent frame type isolation rings are designed to be properly arc-shaped, so that radial movement of the isolation rings can be avoided, inclination of the rollers is prevented, and the rollers are in good linear contact with a roller way; the bearing capacity, the extreme rotating speed and the precision of a shaft are improved; and when stress between the rollers is non-uniform, and a distance between the rollers is increased, the independent isolation rings can reduce the possibility of stressed breakage, and the bearing running reliability is effectively improved.
Description
Technical field
The utility model relates to a kind of slewing bearing, specifically relates to a kind of independent blocks type isolating ring biserial angular contact cylindrical roller slewing bearing, and it belongs to field of bearings.
Background technique
Some heavy machine tool Work turning table will bear very large thrust load and tilting moment when work.Under the definite prerequisite of boundary dimension, the structure in the past adopting is merely able to bear the load in certain limit, when unbalance stress, spacing strengthen between roller, the problem because of pressurized fracture easily occurs.
Summary of the invention
In view of the defect that prior art exists, the purpose of this utility model is that a kind of biserial angular contact cylindrical roller slewing bearing that adopts independent blocks type isolation ring type will be provided.
For achieving the above object, the technological scheme that the utility model adopts is independent blocks type isolating ring biserial angular contact cylindrical roller slewing bearing, and it comprises: outer ring, inner ring, roller and retainer; Outer ring is provided with mounting hole, and mounting hole is equipped with stifled roller piece, and outer ring and stifled roller piece are fixed by taper pin, it is characterized in that: described retainer is independent blocks structure, and retainer is completely loaded in the raceway of inner ring and outer ring; Roller is positioned in retainer pocket hole, and roller is in the 45° angle raceway that circumferential array forms in inner ring and outer ring successively.
The surface of contact of described adjacent two independent blocks structure retainers is arc structure.
Described retainer pocket hole face has arc surface and planarea to form.
Described roller is that line contacts with inner ring with the rolling that outer ring forms.
The utility model has the advantage of: adopt independent blocks type isolating ring structure, two independent blocks type isolating ring surface of contact are designed to suitable circular arc, can avoid radially vibration of isolating ring, prevent that roller from tilting, making between roller and raceway is that good line contacts, and improves bearing loading capability, limit speed and precision.When between roller, unbalance stress, spacing strengthen, independently isolating ring can reduce the possibility because of pressurized fracture, effectively improves bearing operation reliability.
