Abstract
A radial roller bearing for a speed reducer of a concrete mixer relates to a component of a speed reducer. The defect that the bearings are easy to be broken in transportation in the prior are. The rollers are in drum shape with an arc working face and are limited on an inner ring, and an arc sliding face matched with the arc working face of rollers is installed at the inner side of an outer ring. The inner and outer rings that can relatively swing are provided, thereby increasing the buffer space, reducing the damages for the bearing in transportation caused by shaking, and guaranteeing the regular service of the mixer.
Description
[technical field]
The utility model relates to a kind of speed reducer parts, specifically is a kind of concrete mixer speed reducer radial roller bearing.
[background technique]
The motor of concrete mixer stirs the bucket rotation by the main shaft drive and stirs after speed reducer (gearbox) slows down, main shaft is fixed on the interior main shaft bearing of speed reducer.It is very big to stir bucket and interior mixed earth material weight thereof, can produce very big pressure to bearing by main shaft.In the transit mixer transportation process, because pavement conditions restriction, transit mixer can produce vibrations, and the inner ring of traditional bearing and outer ring activity space diametrically is very little, stirring the bucket vibrations is not fully cushioned in the big moment of bearing place generation, cause the damage of bearing easily and break, influence transit mixer and normally use.
[model utility content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of concrete mixer speed reducer radial roller bearing, can improve the buffering surplus at the Internal and external cycle that certain rotation space is radially arranged by being provided with, prevent to transport the purpose that middle (center) bearing damages.
For this reason, the utility model is by the following technical solutions: concrete mixer speed reducer radial roller bearing, comprise outer ring, inner ring and be located between the two a plurality of rollers, it is characterized in that described roller is the cydariform with curved working face, and be limited on the inner ring, the inboard, outer ring is provided with the arc sliding surface that matches with the roller curved working face.The arc sliding surface of the curved working face of roller and outer ring matches, and the relative outer ring of inner ring is swung in several angle.When producing vibrations in transportation process, the moment that stirs the bucket generation has certain buffer space to neutralize, and the moment that has reduced bearing is stressed, can effectively prevent damage of bearings, break.
The described inner ring outside is provided with two rollers of axially-aligned on same radial angle, the curved working face length of these two rollers and roller spacing sum make roller be limited at work in the outer ring less than outer ring sliding surface length.
The described inner ring outside is provided with a retainer along circumference, and retainer both sides vertically is respectively equipped with spacing draw-in groove, and roller is located in the spacing draw-in groove symmetrically, and the roller of two groups of symmetries helps between the Internal and external cycle the level and smooth swing to both direction.
Described outer ring axially is spliced by two outer ring chunks, during assembling, and two outer ring chunk amalgamations in opposite directions, with the inner ring clamping wherein, and the end bore minimum of outer ring, amalgamation portion bore maximum, inner ring can not skid off from the outer ring, guarantees reliable operation.
Beneficial effect: the utility model has increased buffer space by the Internal and external cycle that can swing relatively is set, and has alleviated and has shaken the infringement that bearing is caused in the transportation, has guaranteed the normal use of transit mixer.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross section structure schematic representation of the present utility model.
[embodiment]
Concrete mixer speed reducer radial roller bearing as shown in Figure 1, 2, inner ring 2 outsides are provided with retainer 4, retainer both sides vertically is respectively equipped with spacing draw-in groove, several rollers 3 are limited in the spacing draw-in groove, be provided with two rollers of axially-aligned on same radial angle, the curved working face length of these two rollers and roller spacing sum are less than outer ring sliding surface length.Roller is cydariform, and its side is a curved working face.Outer ring 1 axially is spliced by two outer ring chunks, and the inboard is provided with the arc sliding surface, match with the curved working face of roller, and the bore maximum of both sides, outer ring, middle bore maximum, with the inner ring restriction within it.
When stirring bucket vibrations drive main shaft rocked, roller can slide with respect to the arc sliding surface, necessarily radially wobbles the space thereby inner ring and outer ring are had, thereby reaches the purpose that has increased buffer space.
Claims (4)
1, concrete mixer speed reducer radial roller bearing, comprise outer ring, inner ring and be located between the two a plurality of rollers, it is characterized in that: described roller is the cydariform with curved working face, and be limited on the inner ring, the inboard, outer ring is provided with the arc sliding surface that matches with the roller curved working face.
2, concrete mixer speed reducer radial roller bearing according to claim 1, it is characterized in that: the described inner ring outside is provided with two rollers of axially-aligned on same radial angle, the curved working face length of these two rollers and roller spacing sum are less than outer ring sliding surface length.
