Abstract
The present invention relates to a kind of angular contact gear-bearing, which includes outer ring, inner ring, rolling element, retainer；The retainer uses italic formula, the pocket hole bottom of retainer to carry cone root；Further include two annular oil seals between the outer ring and inner ring, which is located at the rolling element both sides；Raceway between the inner ring and outer ring is separated by 30 50mm between double raceway structure and two raceways；It is additionally provided with gear part on the lateral surface of the outer ring.Bearing and gear are carried out Integration Design by the present invention, i.e. the outer shroud design of gear and bearing is structure as a whole, effectively reduces number of parts, alleviate quality, while the stability of power transmission can be improved.The present invention uses double raceway structure simultaneously, and the load-carrying properties of bearing are substantially improved in the case where not increasing bearing appearance and size, are more in line with the requirement of wind electricity pitch variable bearings.
Description
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of angular contact gear-bearing.
Background technology
Bearing is the more common fixed member in engineering machinery.With the rapid development of social economy, market is to axis
The demand held is increasing, it is desirable that also higher and higher.How gear drive and loading ability of bearing effectively to be combined and goes to solve existing skill
The number of components is more in art, quality weight, at the same power transmit poor reliability the problem of be that those skilled in the art need to solve at present
Certainly the technical issues of.
Invention content
It is an object of the invention to provide a kind of angle that bearing capacity is high with defect in view of the above shortcomings of the prior art
Gear-bearing is contacted, to solve the problem of the poor reliability of more the number of components in the prior art, quality weight while power transmission.
The purpose of the present invention is realized by following technical solution.
A kind of angular contact gear-bearing, including outer ring, inner ring, rolling element, retainer；Rolling element is located at inner ring and outer ring
Between raceway；Retainer is in raceway along the circumferential direction by rolling element even partition；The retainer uses italic formula, retainer
Pocket hole bottom carry cone root；Further include two annular oil seals between the outer ring and inner ring, two annular oil seal difference
Positioned at the rolling element both sides；It is characterized in that：Raceway between the inner ring and outer ring be double raceway structure and two raceways it
Between be separated by 30-50mm；It is additionally provided with gear part on the lateral surface of the outer ring.
Further, the gear part is the rack-and-pinion being evenly distributed on the lateral surface of the outer ring.
Further, lubricant is filled in the raceway.
Compared with prior art, the advantages of angular contact gear-bearing of the present invention, is as follows：
1, the raceway between inner ring of the invention and outer ring is double raceway structure, the case where not increasing bearing appearance and size
Under the load-carrying properties of bearing are substantially improved, be more in line with the requirement of wind electricity pitch variable bearings.
2, bearing and gear are carried out Integration Design by the present invention, i.e. the outer shroud design of gear and bearing is structure as a whole,
Number of parts is effectively reduced, quality is alleviated, while the stability of power transmission can be improved.
3, the shoulder block height of the both sides of Internal and external cycle of the invention differs, the shoulder block of side therein process it is relatively low be for
Loading more steel balls, bearing load carrying capacity are reinforced.
4, present invention setting annular oil seal, can effectively seal bearing, prevent dust from entering in raceway, bearing operation noise
Low, friction is small, can be effectively improved the service life that bearing is substantially increased due to bearing failure caused by high-speed resistance.
Description of the drawings
Fig. 1 is the structural schematic diagram of angular contact gear-bearing of the present invention.
In figure：1 inner ring, 2 gear parts, 3 outer rings, 4 retainers, 5 rolling elements, 6 annular oil seals.
Specific implementation mode
Below in conjunction with the structure that present invention be described in more detail of attached drawing 1.
A kind of angular contact gear-bearing, including outer ring 3, inner ring 1, rolling element 5, retainer 4；Rolling element 5 be located at inner ring 1 with
Between the raceway of outer ring 3；Raceway between inner ring 1 and outer ring 3 is separated by 30-50mm between double raceway structure and two raceways,
The load-carrying properties of bearing are substantially improved in the case of not increasing bearing appearance and size, the use for being more in line with wind electricity pitch variable bearings is wanted
It asks.
Retainer 4 is in raceway along the circumferential direction by 5 even partition of rolling element；The retainer 4 uses italic formula, keeps
The pocket hole bottom of frame 4 carries cone root.The shoulder block height of the both sides of the Internal and external cycle of the present invention differs, and the shoulder block of side therein is added
The relatively low of work is to be packed into more steel balls, and bearing load carrying capacity is reinforced.
Gear part 2 is additionally provided on the lateral surface of the outer ring 3.Bearing and gear are carried out Integration Design by the present invention,
That is the outer shroud design of gear and bearing is structure as a whole, and effectively reduces number of parts, alleviates quality, while can be improved dynamic
The stability that power is transmitted.
Further include two annular oil seals 6 between the outer ring 3 and inner ring 1, which is located at described
5 both sides of rolling element；Annular oil seal 6 is arranged in the present invention, can effectively seal bearing, prevent dust from entering in raceway, bearing operation is made an uproar
Sound is low, and friction is small, can be effectively improved the service life that bearing is substantially increased due to bearing failure caused by high-speed resistance.
The basic principles and main features and its advantage of the present invention have been shown and described above.The skilled worker of the industry answers
The understanding, the present invention are not limited by above-mentioned implementing regulations, are only intended to illustrate described in above-mentioned implementing regulations and specification
The principle of the present invention, under the premise of not departing from the principle of the invention and range, the present invention can also have various changes and modifications, these
Changes and improvements belong in scope of the claimed invention.
The claimed scope of the invention is the same as appended claims and other equivalent thereofs.
