Abstract
The invention relates to a slewing support bearing, specifically to an independent frame type isolating ring double column angular contact cylindrical roller slewing support bearing, which belongs to the field of bearings. The slewing support bearing comprises an outer ring, an inner ring, rollers and cages, wherein the outer ring is provided with an installing hole, a roller blocking piece is arranged in the installing hole, and the outer ring and the roller blocking piece are fixed through a taper bolt. According to the invention, an independent frame type isolating ring structure is adopted and the contact surface of two independent frame type isolating rings is designed to be of a proper arc shape, so radial endplay of the isolating rings is avoided, inclination of the rollers is prevented, the rollers have good line contact with raceways, and the bearing capability, limit rotating speed and precision of the bearing are improved; when stress between the rollers is uneven and spacing between the rollers is increased, the independent isolating rings enable the possibility of cracking caused by stress to be reduced and reliability of operation of the bearing to be effectively improved.
Description
Technical field
The present invention relates to a kind of slewing bearing, specifically relate to a kind of independent blocks type isolating ring biserial angular contact cylindrical roller slewing bearing, it belongs to field of bearings.
Background technique
Some heavy machine tool Work turning table will bear very large thrust load and tilting moment in the time of work.Under the definite prerequisite of boundary dimension, the structure in the past adopting is merely able to bear the load in certain limit, in the time that 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 object of the invention is to provide a kind of biserial angular contact cylindrical roller slewing bearing that adopts independent blocks type isolation ring type.
For achieving the above object, the technical solution adopted in the present invention 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; One side is convex shaped arc structure, and on the other side is concave circular arcs.
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.
Described retainer adopts nylon material.
The installation process of independent blocks type isolating ring biserial angular contact cylindrical roller slewing bearing as above is as follows: bearing inner race is alignd with machine equipment with cycle surface, by one group of retainer piece narrow end surface that roller is housed inwardly, roller mounting hole along outer ring is sent in raceway, slowly rotary inner ring, make roller part roll into raceway the inside, suitably exposed portions serve retainer; The retainer piece that again another is assembled with to roller is sent into raceway, and adjacent last group, then rotary inner ring slowly, remaining retainer is according to said method installed, until install last group retainer piece.To block up roller packaged enter mounting hole, and with the fixing stifled roller piece of taper pin.
The invention has the advantages that: 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.In the time that between roller, unbalance stress, spacing strengthen, independently isolating ring can reduce the possibility because of pressurized fracture, effectively improves bearing operation reliability.
