Abstract
The utility model discloses a cylindrical roller bearing with a gear. The cylindrical roller bearing comprises a bearing inner ring and a plurality of cylindrical rollers and further comprises a gear, wherein rolling paths are arranged on the surface of the outer diameter of the bearing inner ring; the cylindrical rollers are circumferentially arranged in the rolling paths; the bearing inner ring and the cylindrical rollers are arranged in the axle hole of the gear; the axle hole wall of the gear serves as an outer rolling path and is in contact with the cylindrical rollers. The cylindrical roller bearing provided by the utility model has a series of advantages as follows: the gear is prevented from deforming; the approximate ideal clearance requirement is met while the cylindrical roller bearing runs; the transmission precision of the gear and the bearing capacity of the cylindrical roller bearing are improved.
Description
Technical field
The utility model belongs to technical field of bearings, relates in particular to a kind of roller bearing.
Background technique
In the gear transmission application, have a kind of occasion to require gear and axle to relatively rotate, as planet wheel in epicyclic train, planet wheel revolves round the sun around sun gear, and planet wheel itself is also wanted rotation, is can be in relative rotation between the axle that therefore requires planet wheel to be mated.
Present this occasion uses the bearing main feature to be: bearing outer ring adopts interference fit to be pressed in the gear internal diameter, and there is following shortcoming in this mode:
1, because the processing of gear internal diameter is generally more coarse, circularity, tapering all can be delivered on bearing outer ring, cause outer ring raceway distortion, bearing clearance to change, and lose original precision level, cause bearing early failue;
2,, because bearing rotation precision changes, affect gear-driven precision;
3, due to spatial constraints, rolling element can't be strengthened, the bearing capacity of bearing also is restricted.
The model utility content
For this reason, the roller bearing with gear that technical problem to be solved in the utility model is to provide a kind of distortion of having avoided outer ring and gear interference fit to produce, requires, improves gear-driven accuracy and bearing load carrying capacity while guaranteeing bearing working near desirable play, the deficiency that exists to overcome prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of roller bearing with gear, comprise on the external diameter surface of bearing inner race, many cylindrical rollers, described inner ring and have raceway, described many cylindrical roller circumferential arrangement are in described raceway, it is characterized in that: also include gear, described bearing inner race and many cylindrical rollers are positioned at the axis hole of described gear, and the axis hole wall of described gear contacts with described many cylindrical rollers as outer ring raceway.
Described axis hole wall is positioned at described many cylindrical roller both sides and has respectively caulking groove, is provided with jump ring in described caulking groove.Such structure, guaranteed that cylindrical roller does not axially come off.
In embodiment of the present utility model, the external diameter surface of described inner ring has the twice raceway, and described a plurality of cylindrical rollers divide two circles to be distributed in respectively in described twice raceway.
The surface of described axis hole wall is protuberance shape, and hardness reaches HRC60～65.
Adopt technique scheme, compared with prior art, the utlity model has following advantage:
1, by bearing outer ring and design of gears are integrated part, the distortion of having avoided outer ring and gear interference fit to produce;
2, eliminated the impact of interference fit on bearing clearance, while better guaranteeing bearing working near desirable play requirement;
3, the gear internal diameter, directly as bearing outer ring ball track, has reduced integrating error, has improved the transmission accuracy of gear;
4, removed the outer ring of bearing, the roller dimension of bearing and quantity are all had living space and are increased, thereby have improved the bearing capacity of bearing, and then have improved working life;
4, reduce repeatedly assembling, improved the reliability of whole assembly, also reduced the cost of manual assembly.
Therefore, the roller bearing with gear of the present utility model has the gear of avoiding generation distortion, requires, improves the series of advantages such as gear-driven accuracy and bearing load carrying capacity while guaranteeing bearing working near desirable play.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
In figure:
The 01-gear, 02-bearing inner race, 03-jump ring, 04-cylindrical roller, 11-axis hole wall, 12-caulking groove, 21-raceway.
Embodiment
As depicted in figs. 1 and 2, the roller bearing with gear of the present utility model, comprise gear 01, bearing inner race 02, many cylindrical rollers 04.
Wherein, the external diameter surface of bearing inner race 02 offers twice raceway 21, and 04 item minute two circle of many cylindrical rollers is arranged in two ends raceway 21 around a circle respectively.The axis hole wall 11 that bearing inner race 02 and many cylindrical rollers 04 are positioned at the axis hole of the axis hole of gear 01 and gear 01 contacts with many cylindrical rollers 04 as outer ring raceway.
For avoiding cylindrical roller axially to come off, be positioned at many cylindrical rollers 04 both sides at axis hole wall 11 and have respectively caulking groove 12, be provided with jump ring 03 in caulking groove 12.
And the surface of axis hole wall is protuberance shape, carries out localized quench hardening and processes, and hardness reaches HRC60～65.
Adopt said structure, this roller bearing with gear of the present utility model has the gear of avoiding and produces distortion, requires, improves the series of advantages such as gear-driven accuracy and bearing load carrying capacity while guaranteeing bearing working near desirable play.
But, those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and not be used as restriction of the present utility model, as long as in connotation scope of the present utility model, to the above embodiment's variation, modification, all will drop in claims scope of the present utility model.
