Abstract
The utility model relates to a part which is used for isolating rolling elements in a cross cylindrical roller turntable axletree, in particular to an isolation block for the cross cylindrical roller turntable axletree. The isolation block is arranged between two adjacent rollers in the axletree. Cylinder-shaped grooves (2) are arranged on two end surfaces of the isolation block, wherein the cylinder-shaped grooves contact rollers. Axes of the cylinder-shaped grooves (2) arranged on the two end surfaces are perpendicular to each other. An included angle is formed by the axes of the cylinder-shaped grooves and a mid vertical plane of the two adjacent rollers. And the axes of the cylinder-shaped grooves (2) are parallel to generatrices of the rollers. Oil storage grooves are arranged on four non-working surfaces of the isolation block. The isolation block for the cross cylindrical roller turntable axletree solves the problem that the cylinder-shaped grooves of the isolation block cannot fit the rollers well and enables the axletree to rotate more smoothly and flexibly. Meanwhile, the isolation block for the cross cylindrical roller turntable axletree solves the problem that lubricant flows difficultly between the rolling elements and improves lubricating property of the axletree.
Description
Technical field
The utility model relates to the part of separation roller in a kind of crossed cylindrical roller turntable bearing, is specifically related to a kind of crossed cylindrical roller turntable bearing spacing block.
Background technique
The crossed cylindrical roller turntable bearing is comprised of inner ring, outer ring, roller and spacing block, two raceways that are mutually 90 ° are respectively arranged on inner ring and the outer ring, roller cross arrangement on the raceway between inner ring and outer ring, adjacent rollers is separated with spacing block, respectively there is a cylindrical groove on the spacing block two sides, direction is consistent with the generatrix direction of adjacent rollers, and ratio of curvature roller curvature is bigger.The present general spacing block of employing of institute, two the orthogonal cylindrical grooves of pair of parallel face processing at cuboid, the cylindrical groove axis is vertical with the end face of cuboid, because inner ring, outer ring raceway are ring surface, so end face and the out of plumb of actual adjacent two roller buses and spacing block.Like this, the applying that the cylindrical groove of spacing block and adjacent two rollers can not be good affects the revolution of bearing.Little at swing diameter, in the few bearing of roller, this impact is even more serious.In addition, for better guide rolls motion, the curvature of spacing block cylindrical groove is general and roller curvature is very approaching, and the Length Ratio roller is slightly short, and this design can cause oiling agent to be difficult to circulation between rolling element, affects the greasy property of bearing.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of crossed cylindrical roller turntable bearing spacing block.
The utility model adopts following technological scheme for finishing above-mentioned purpose:
A kind of crossed cylindrical roller turntable bearing spacing block, described spacing block are arranged between interior adjacent two rollers of bearing; Have on the both ends of the surface of spacing block and the contacted cylindrical groove of roller, and the axis of cylindrical groove that both ends of the surface have is mutually vertical; Have angle between the middle vertical plane between the axis of described cylindrical groove and adjacent two rollers, and the axis of described cylindrical groove is parallel with the bus of roller; Has oil storage tank on four non-working surfaces of described spacing block.
Described oil storage tank is four, includes two dovetail grooves and two arc-shaped slots, and wherein two dovetail grooves are adjacent, and two arc-shaped slots are adjacent; The parallel installation direction with spacing block of the seamed edge of described dovetail groove.
A kind of crossed cylindrical roller turntable bearing spacing block that the utility model proposes has the structure of certain angle between the axis of employing cylindrical groove and the middle vertical plane between adjacent two rollers, make the axis of cylindrical groove parallel with the bus of roller; Having solved the bad problem of spacing block cylindrical groove and roller applying makes the bearing revolution more smooth-going flexibly; Circumferential surface at spacing block has oil storage tank, solved the problem of oiling agent difficult circulation between rolling element, improved the greasy property of bearing, the seamed edge of dovetail groove is over against the installation direction of spacing block in addition, so that can wrongly installed during spacing block in assembling, improved working efficiency.

Fig. 1 is front elevation of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is top view of the present utility model.
Fig. 4 is stereogram of the present utility model.
Among the figure: 1, dovetail groove, 2 cylindrical grooves, 3, arc-shaped slot.
Embodiment
With specific embodiment the utility model is illustrated by reference to the accompanying drawings:
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of crossed cylindrical roller turntable bearing spacing block, described spacing block are arranged between interior adjacent two rollers of bearing; Have on the both ends of the surface of spacing block and the contacted cylindrical groove 2 of roller, and the axis of cylindrical groove that both ends of the surface have 2 is mutually vertical; Have angle between the middle vertical plane between the axis of described cylindrical groove 2 and adjacent two rollers, and the axis of described cylindrical groove 2 is parallel with the bus of roller; Has oil storage tank on four non-working surfaces of described spacing block; Described oil storage tank is four, includes two dovetail grooves 1 and two arc-shaped slots 3, and wherein two dovetail grooves 1 are adjacent, and two arc-shaped slots 3 are adjacent; Four oil storage tanks make oiling agent mobile more convenient between rolling element, have improved the greasy property of bearing; The seamed edge of described dovetail groove 1 can wrongly installed when guaranteeing assembling over against the installation direction of spacing block.
