Abstract
The utility model discloses a steel cage for radial raceways of three rows of pin rollers. The steel cage is composed of a plurality of sections of steel belts, wherein each section of steel belt is provided with a plurality of pockets; and the diameter of each pocket is a little greater than those of rollers. The steel cage has the effects that the a certain distance is formed between two adjacent pockets, so that isolation of radial rollers of three rows of pin rollers and adjacent rollers can be effectively achieved when rotary supporters of the three rows of pin rollers are vertically used; the condition that the cage deviates from a normal work position, inclines or is deadly locked is avoided in an operating process; service performance of the three rows of pin rollers is provided; and use under a vertical condition is ensured.
Description
Technical field
The utility model belongs to a kind of engineering machinery pivoting support retainer, and what relate generally to is radially raceway steel retainers of a kind of three row's rollers.
Background technique
Between the radial roller of three row's roller pivoting supports spacing block is arranged generally, with the friction between the eliminate roller.Because three row's roller pivoting supports generally all are that level is used, so spacing block is adopted in the isolation of radial roller, concave spherical surface is made, to adapt with roller near roller in its two ends.But when pivoting support vertically uses, because spacing block is less, and do not connect mutually, spacing block is easy to depart from oneself working position under Action of Gravity Field in operation process, wedge angle and roller are contacted, cisco unity malfunction, when serious spacing block operation process around Pivot Point Center rotate, crooked, bear against, cause situation stuck between roller, will lose efficacy in advance because the spacing block problem makes pivoting support like this.
Summary of the invention
For solve present radial roller spacing block under vertical state, work easily crooked, depart from normal operation position and cause the problem that bears against stuck situation, the utility model proposes a kind of radially raceway steel retainer of three row's rollers, can guarantee the running of retainer and roller, in the operation process retainer can not produce yet crooked, bear against.
For achieving the above object, the technological scheme that the utility model is taked is: at least two sections steel bands consist of, and it is characterized in that described every section steel band has 1 pocket hole at least, and the diameter in described pocket hole is slightly less than roller diameter, just matches with radial roller.The wide S 〉=5mm of muscle between two pocket holes, steel band also to guarantee end to end the wide S 〉=5mm of muscle.Gap delta≤the 2mm of every adjacent two steel bands.
Effect of the present utility model is: because there is the spacing of not joining in adjacent two pocket holes, when guaranteeing running turn round with roller in the pocket hole of retainer, in addition, owing to can keep certain gap between the adjacent pocket of the retainer hole, can not produce roller contact with roller and produce the friction bear against, when three row's roller pivoting supports vertically use, can effectively realize the isolation of pivoting support radial roller and adjacent rollers, in operation process, avoid retainer to depart from normal operation position, crooked, stuck situation, improve the usability of pivoting support, guarantee the application under vertical state.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is A-A assembling schematic representation of Fig. 1.
Accompanying drawing 3 is erection drawings of an embodiment of the present utility model.
Among the figure, 1, the gap of pocket hole 2, upper circle 3, steel band 4, radial roller 5, lower circle 6, ring gear S, the wide δ of muscle, two ends steel band.
Embodiment
In Fig. 1, has 1 pocket hole 1 on every section steel band 3 at least, the wide S 〉=5mm of the muscle in adjacent two pocket holes.Steel band also will guarantee the wide S 〉=5mm of muscle end to end.
In Fig. 2, the steel retainer of a product consists of the placement gap delta≤2mm of per two adjacent steel bands 3 by two sections or multistage steel band 3.
In Fig. 3, upper circle 2 and lower circle 5 have consisted of the outer ring of three row's roller pivoting supports, internal plane has set outstanding annular table terrace on the lower circle 5, upper circle 2 lower interior have the recess step face, between two step surfaces radial roller 4 is arranged, steel band 3 is provided with pocket hole 1, the slightly larger in diameter in pocket hole 1 is in radial roller 4 diameters, each pocket hole 1 corresponding 1 radial roller 4, wide S 〉=the 5mm of the muscle in adjacent two pocket holes, each three row's roller pivoting support can be placed a plurality of steel bands 3, the placement gap delta≤2mm of per two adjacent steel bands 3 according to the product size.
Upper circle 2, lower circle 5, radial roller 4 and the pivoting support structural member of ring gear 6 for knowing, steel band 3 is provided with pocket hole 1 structure and forms the steel retainer, is used with radial roller 4, has consisted of radially raceway steel retainer of three row's roller pivoting supports.
Claims (3)
1. arrange radially raceway steel retainer of roller for one kind three, be made of at least two sections steel bands, it is characterized in that described every section steel band has 1 pocket hole at least, the diameter in described pocket hole is slightly less than roller diameter, just matches with radial roller.
2. three row's rollers according to claim 1 raceway steel retainer radially is characterized in that two wide S 〉=5mm of the muscle between the pocket hole, steel band also to guarantee end to end the wide S 〉=5mm of muscle.
3. according to claim 1 three arrange radially raceway steel retainer of rollers, it is characterized in that the gap delta≤2mm of every adjacent two steel bands.
