Abstract
The utility model relates to a turntable bearing with 90-degree double linear rollaway nests. The turntable bearing comprises an outer ring (1), an inner sealing ring (2), an inner ring (3), cone-shaped rolling balls (4), an outer sealing ring (5), and a retaining bracket (6). Single rollaway nests which correspond to each other and have the 90-degree section are simultaneously arranged on the inner diameter end face of the outer ring and the outer diameter end face of the inner ring. The two linear faces of the single rollaway nests relative to symmetrical central lines are 45 degrees. A plurality of cone-shaped rolling balls are assembled in the outer ring single rollaway nest and the inner ring single rollaway nest through the retaining bracket. The cone-shaped faces at both ends of the cone-shaped rolling balls are respectively in contact with the two linear faces of the outer and inner rings, so that the turntable bearing with 90-degree double linear rollaway nests provided by the utility model can bear a radial load, an axial load and a capsizing moment, and the inner and outer rings are sealed through the inner and outer sealing rings. The processing technology is remarkably improved, and the installation space of a wind power generator is saved.
Description
Technical field
The utility model belongs to technical field of bearings, specially refers to a kind of turntable bearing with 90 ° of bilinear raceways.
Background technique
The pitch variable bearings that wind-driven generator uses mostly is two rolling way turntable bearings, and this pair rolling way turntable bearing can satisfy the bearing capacity of wind-driven generator, and its friction torque also meets the usage requirement of wind-driven generator.
Although above-mentioned pair of rolling way turntable bearing can satisfy the usage requirement of wind-driven generator, but the bad grasp of some processing technique when the two raceway of turning processing, parallel error problem such as two raceways, such as the shape of two raceways problem that whether can keep consistency, such as problems such as two raceways after the processing are difficult for being trimmed.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of turntable bearing with 90 ° of bilinear raceways, the bilinear raceway of this turntable bearing forms single raceway, two included angle of straight line of described single raceway are 90 °, to justify the tapered spin of spin two ends truncation around 90 ° of bilinear raceways, the conical surface of taper spin directly contacts with the bilinear raceway after the truncation, therefore this turntable bearing can bear radial load, thrust load and tilting moment simultaneously, processing technique is obviously improved, and has saved the wind-driven generator installing space.
For achieving the above object, the utility model adopts following technological scheme:
A kind of turntable bearing with 90 ° of bilinear raceways, this turntable bearing comprises the outer ring, inner seal ring, inner ring, the taper spin, exterior seal ring, retainer, be provided with simultaneously mutual correspondence and its cross section is single raceway of 90 ° at the external diameter end face of the internal diameter end face of outer ring and inner ring, two planareas of described single raceway relatively its symmetrical center line are all 45 °, these 45 ° two crossing planareas consist of 90 ° of bilinear raceways, described single raceway is at the equal raceway in the form of a ring of the external diameter end face of the internal diameter end face of outer ring and inner ring, in the described single raceway in outer ring and the described single raceway of inner ring, be equipped with several taper spin by retainer, the conical surface of each taper spin one end contacts with two planareas of the described single raceway in outer ring, the conical surface of each taper spin the other end contacts with two planareas of the described single raceway of inner ring, the maximum diameter of taper spin is greater than the vertical interval of described single raceway one planarea in outer ring to described single raceway one planarea of corresponding inner ring, end face in the outer ring is provided with the external sealed annular groove, configuration exterior seal ring in the described external sealed annular groove, the inner ring other end opposite with outer ring one end face is provided with the inner seal ring groove, described inner seal ring groove configuration inner seal ring.
Above-mentioned taper spin its two ends sphere under stationary state is become the ring-type conical surface of two symmetries by truncation respectively, and the symmetrical center line angle of the relative taper spin of each described ring-type conical surface is 90 °.
Owing to adopt as mentioned above technological scheme, the utility model produces following beneficial effect:
1, turntable bearing of the present utility model is a kind of single race bearing, two planareas of single raceway are 90 ° in its cross section, the taper spin that matches with single raceway makes turntable bearing can bear simultaneously radial load, thrust load and tilting moment, processing technique is obviously improved, and has saved the wind-driven generator installing space.
2, the utlity model has simple in structurely, the relatively two rolling way turntable bearings of processing mode become is more prone to control, has improved the overall performance of the utility model turntable bearing.
