Abstract
The utility model relates to a spline lubrication structure, which comprises an external spline and a lubricating nozzle, wherein a groove is formed in a shaft of the external spline; the lubricating nozzle is dead against the groove; an oil hole is also formed in the external spline; and the oil hole connects the external spline with the groove. The spline lubrication structure is ingeniously designed according to parts structures, and has special advantages in aspect of spline lubrication; and the spline using the lubrication structure has the beneficial effect that a lubrication effect is significantly improved compared with oil-mist lubrication.
Description
Technical field
The utility model relates to a kind of spline lubricating structure.
Background technique
Spline is a kind of common drive mechanism, and because its length of action is long, inside and outside spline cooperatively interacts, directly lubricated very difficult, so generally adopt simple oil mist lubrication, lubrication effect is poor, therefore in the environment of a few thing inclement condition, spline is easy to cause damage.
Summary of the invention
The purpose of this utility model is to provide a kind of spline lubricating structure, solves the problem of the abominable spline insufficient lubrication of operating conditions.
The technical solution of the utility model is, spline lubricating structure comprises external splines, lubricating nozzle, is provided with groove on the axle of described external splines, and described lubricating nozzle faces groove, also be provided with oilhole on described external splines, described oilhole connects external splines and groove.
The utility model arranges lubricating point at needs lubricated spline positions, and design groove oil-collecting on male splined shaft is simultaneously at external spline teeth groove relevant position processing oilhole.By the lubricant oil that lubricating nozzle ejects, after collecting in groove, enter the spline place by oilhole, be lubricated.The utility model is according to the design of part characteristics, and ingehious design has unique advantage at spline aspect lubricated, uses the spline of this lubricating structure, and lubrication effect is significantly increased than oil mist lubrication.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, spline lubricating structure comprises external splines 1, lubricating nozzle 3, is provided with groove on the axle of described external splines 1, and described lubricating nozzle 3 faces groove, also is provided with oilhole 2 on described external splines 1, and described oilhole 2 connects external splines 1 and groove.
