Abstract
The utility model discloses a kind of ball cage V-type retainer, comprise retainer body, retainer body is provided with several for placing the steel ball hole of steel ball, the upper and lower both sides of described steel ball hole also also offer oil groove near the position at two ends, it is characterized in that: described retainer body is protrude V-shaped shape in the middle of thin-walled annular, its both sides keep arc-shaped to extend from intermediate portion respectively to upper and lower two ends, and tilt to central direction, and two ends are symmetrical up and down, it is less that the structure of this retainer compares traditional spherical shape, it is more reasonable that circular arc contour moves towards structure, make sphere activity space larger and universal movement is wider.
Description
Technical field:
The utility model belongs to field of mechanical technique, relates to a kind of retainer, is specifically related to a kind of ball cage V-type retainer.
Background technique:
The extensive use on wheeled vehicle of ball cage.Usually, ball cage is made up of star sleeve, outer race, steel ball and retainer.Retainer is arranged between star sleeve, outer race, and is arranged in the steel ball hole of retainer by steel ball.Through patent retrieval, a kind of ball cage retainer of novelty disclosed in ZL200620043198.2, it solves the problem that lubrication effect in existing ball cage between retainer and foreign steamer is bad.Its profile is smooth Surface of Sphere, and is provided with several uniform steel ball holes, is provided with some oil grooves outside described retainer, and the steel ball hole that the two ends of every bar oil groove are all adjacent is connected.Because the lubricating grease in ball cage can enter steel ball hole place, and the oil groove on retainer communicates with steel ball hole, and that is lubricating grease can enter in oil groove through steel ball hole, ball cage high lubricating effect, the long service life of novel ball cage retainer.
But, V-type retainer due to the type is profile is smooth spheroidal, itself and bell shell with the use of time, the space on retainer both sides obviously diminishes, when steering wheel gets to certain angle, steering angle is restricted, cause turn to not smooth, there is narrow limitation in this structure Universal active space, and activity space is little.
Model utility content:
In order to overcome the deficiency of background technique, the utility model provides a kind of ball cage V-type retainer, solves the narrow limitation in existing retainer Universal active space, the problem that activity space is little, makes overall structure more reasonable.
The technological scheme that the utility model adopts: a kind of ball cage V-type retainer, comprise retainer body, retainer body is provided with several for placing the steel ball hole of steel ball, the upper and lower both sides of described steel ball hole also also offer oil groove near the position at two ends, it is characterized in that: described retainer body is protrude V-shaped shape in the middle of thin-walled annular, its both sides keep arc-shaped to extend from intermediate portion respectively to upper and lower two ends, and tilt to central direction, and two ends are symmetrical up and down.
By adopting above technological scheme, V-type retainer center of the present utility model is protruded, and both sides keep circular arc difference up downward-extension, and by high-precision manufacturing, finally make the space on retainer both sides obviously increase, steering wheel than spherical structure in the past more makes a call to 5.3 angles; Make steering angle unrestricted, turn to also more smooth, it is less that the structure of this retainer compares traditional spherical shape, and it is more reasonable that circular arc contour moves towards structure, makes sphere activity space larger and universal movement is wider.
As structure optimization of the present utility model, the shape of described steel ball hole is rectangle.
By adopting above technological scheme, rolling steel balls can be assembled in steel ball hole, when ball cage retainer when doing universal movement just does corresponding universal movement with outer race.
As structure optimization of the present utility model, described steel ball hole has 6.
By adopting above technological scheme, making steering angle unrestricted, turning to also more smooth, avoiding occurring stuck phenomenon.
Accompanying drawing illustrates:
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the utility model embodiment front view.
1-retainer body in figure, 2-steel ball hole, 3-oil groove
Embodiment:
Below in conjunction with accompanying drawing, the utility model embodiment is described further: as shown in Figures 1 and 2, a kind of ball cage V-type retainer, comprise retainer body (1), described retainer body (1) is in thin-walled annular, its both sides keep arc-shaped to extend from intermediate portion respectively to upper and lower two ends, and tilt to central direction, and two ends are symmetrical up and down; Retainer body (1) is also provided with 6 for placing the steel ball hole (2) of steel ball.
Described steel ball hole (2) quantity can also be 8,10,12 to be applicable to the ball cage universal joint of various different size.
The retainer of common spherically type of comparing, the utility model example structure is less, and take up room also less, rational in infrastructure, Universal active space is larger.
As shown in Figure 2, the shape of described steel ball hole (2) is rectangle, described steel ball hole (2) up and down both sides also also offers oil groove (3) near the position at two ends, lubricant oil realizes steel ball lubrication by oil groove (3), make commutation more smooth, avoid occurring stuck phenomenon.
More than this novel embodiment; not thereby utility patent scope of the present utility model is limited; every utilize this novel specification and accompanying drawing content institute as equivalent structure or the conversion of equivalent flow process; or be directly or indirectly used in other correlative technology fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (3)
1. a ball cage V-type retainer, comprise retainer body (1), retainer body (1) is provided with several for placing the steel ball hole (2) of steel ball, described steel ball hole (2) up and down both sides also also offers oil groove (3) near the position at two ends, it is characterized in that: described retainer body (1) is middle in thin-walled annular protrudes V-shaped shape, its both sides keep arc-shaped to extend from intermediate portion respectively to upper and lower two ends, and tilt to central direction, and two ends are symmetrical up and down.
