Abstract
The utility model relates to a can strengthen pendulum dynamic stability's a month tooth form cylindrical roller combination bearing is sealed to non - in pairs, it holds the combination by two sets of months tooth axis and forms, and an arbitrary sleeve contracting draws together convex outer lane, convex holder and a plurality of cylindrical roller, and the holder is installed in the outer lane inboardly, and in cylindrical roller installation and the cage pocket, the holder both ends respectively are equipped with a support, and two sets of bearings pass through the leg joint combination. The utility model discloses a holder holds the closed crescent moon profile shaft of two non -s and makes up an organic whole, and the swing is held with individualistic crescent moon profile shaft and is compared simultaneously, has not only increased the load -carrying ability while but also strengthened during operation wobbling stationarity, has improved life greatly.
Description
Technical field
The utility model relates to technical field of bearings, particularly a kind of cylindrical roller combination bearing.
Background technique
In prior art, roller bearing is primarily of outer ring, inner ring, rolling element, retainer composition, and outer ring, retainer, inner ring are all a completely circular structure, but meeting the use occasion of swinging mechaism, as plunger pump, only reciprocally swinging within the scope of several angle during bearing working, instead of the rotation of full circle.Therefore, roller bearing of the prior art can not play its structure characteristic, causes unnecessary waste, and single-row selenodont bearing seems thin and steady not.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of paired non-close selenodont cylindrical roller combination bearing strengthening swing stability.
For solving above technical problem, the technical solution adopted in the utility model is: a kind of non-close selenodont cylindrical roller combination bearing in pairs, combined by two cover crescent moon bearings, any a set of bearing comprises circular arc outer ring, circular arc retainer and some cylindrical rollers, retainer is arranged on inside outer ring, cylindrical roller is installed in retainer pocket hole, and retainer two ends are respectively provided with a support, and two cover bearings connect combination by support.
As preferred technological scheme, a support is respectively established in side, retainer two ends, and wherein an end support is provided with plug, and the other end support is provided with jack.
The utility model, is swung two non-close selenodont bearing pack integrators by retainer simultaneously, compared with single selenodont bearing, has both increased the stationarity swung when load-carrying ability in turn enhances work simultaneously, and has substantially increased working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the explosive view of Fig. 1.
In figure, 1-outer ring, 2-retainer, 3-cylindrical roller, 4-support.
Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
One shown in Fig. 1 paired non-close selenodont cylindrical roller combination bearing, combined by two cover crescent moon bearings, any a set of bearing comprises circular arc outer ring 1, circular arc retainer 2 and some cylindrical rollers 3, retainer 2 is arranged on inside outer ring 1, be fixed on swinging mechaism outside outer ring, slide along retainer cambered surface.Retainer 2 arc length is greater than outer ring 1 arc length, to meet oscillating stroke needs.
Cylindrical roller 3 is installed with in retainer 2 pocket hole, and retainer 2 adopts nylon material, and pocket hole openings of sizes is less than cylindrical roller shaft section, firmly cylindrical roller 3 need be pushed pocket hole during installation, and under normal operating condition, cylindrical roller 3 is de-hole not easily.
Side, retainer 2 two ends shown in Fig. 2 is respectively provided with a support 4, two and overlaps bearing by support 4 connection combination.Wherein an end support 4 is provided with plug, and the other end support 4 is provided with jack, and two cover bearing inserting mode combine.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection domain of the present utility model.
