Abstract
The utility model relates to a bearing, and particularly relates to a cylindrical and angular-contact combined bearing with a large aligning angle, belonging to the field of construction machinery. According to the cylindrical and angular-contact combined bearing, an angular-contact and cylindrical structure combined mode is adopted; a joint structure is additionally arranged in a bearing structure, so that the bearing not only can bear axial force, but also is required to be capable of bearing radial force, and has a relatively-large aligning angle; meanwhile, retaining racks of cylindrical and angular-contact structures are of open semi-structures and are nylon racks; and the rotating speed is increased, and the weight of the bearing is greatly reduced. A multi-shape inner ring structure and a direct forging process molding technology are adopted, so that the cost is saved, and the subsequent processing efficiency is increased; and during bearing processing, the dual-groove once grinding for a straight rolling way and a ball rolling way of inner rings is realized through repeated tooling production and testing, so that the industrialization efficiency is increased.
Description
Technical field
The utility model relates to a kind of bearing, specifically relates to a kind of cylinder angle contacting combination bearing with big aligning angle, and it belongs to engineering machinery field.
Background technique
Along with the continuous development of lifting industry, the performance of lifting appliance is also in continuous improve, and the transmission position of playing equipment is the nucleus equipment of lifting appliance.Bearing requires also in continuous increase it as the important component part at lifting appliance transmission position.Not only require bearing can bear axial force, require its energy bearing radial force again, and will have bigger aligning angle.At present, playing the bearing that equipment transmission position mainly is suitable for is selfaligning roller bearing, and it is with having bigger aligning angle, and can bearing radial force; But it only can bear less axial force, and it more and more can not satisfy the requirement of lifting appliance.Thereby study and a kind ofly can bear axial force, require it can bearing radial force again, and the bearing that will have a bigger aligning angle be imperative.
Summary of the invention
In view of the problem that prior art exists, the purpose of this utility model is will provide a kind of can bear axial force, requires its energy bearing radial force again, and will have the cylinder angle contacting combination bearing at bigger aligning angle.
To achieve these goals, the technological scheme that the utility model adopts is a kind of cylinder angle contacting combination bearing with big aligning angle, and it comprises: bearing outer ring, bearing inner race and retainer is characterized in that: it also comprises steel ball and roller; Described bearing outer ring is two halves formula structure, is respectively first outer ring and second outer ring, and first outer ring and second outer ring link together at external diameter surface by O type circle; Retainer is installed between bearing outer ring and the bearing inner race, described retainer is made of roller cage and ball retainer, steel ball is installed in the ball retainer pocket hole, and contact with first outer ring and bearing inner race, roller is installed in the roller cage pocket hole, and with second outer ring and bearing inner race connecting part.
Described bearing inner race comprises first inner ring and second inner ring, and first inner ring contacts with roller and steel ball, and second inner ring is positioned at first inner ring outside.
Described roller cage and ball retainer adopt nylon bracket.
Described roller cage and ball retainer are open type half hitch structure.
Described roller cage adopts the outer guide structure of shape wave.
Advantage of the present utility model is: the pattern that adopts the combination of angle contacting and round column structure; And articulation structure is increased in the bearing structure, make bearing can bear axial force, require it can bearing radial force again, and will have bigger aligning angle, round column structure adopts open type half hitch structure with the retainer of angle contacting structure simultaneously, and the employing nylon bracket; Both weight reduction improved rotating speed, had alleviated bearing weight again greatly.Adopt the interior coil structures of multiform shape, the straight forming technology of forging process has been saved cost, and has improved following process efficient; The straight raceway of inner ring and ball receway have realized that by repeatedly frock making and test two ditches once grind, and have improved industrialization efficient in the bearing processing.
