Abstract

The invention relates to a lubrication structure of a spline transfer bar.The lubrication structure comprises the spline transfer bar, a nozzle, an oil distribution sleeve and a plug.The spline transfer bar is of a hollow structure, the two ends of the spline transfer bar are provided with external splines, the nozzle is located at one end of the spline transfer bar, and an oil spraying opening of the nozzle is right opposite to the interior of the spline transfer bar.The oil distribution sleeve is annular and is internally provided with an interlayer, the interlayer is provided with an oil distribution opening, and the part, located between the interlayer and an oil inlet, of the oil distribution sleeve is provided with an oil shedding opening.The plug is installed at the other end of the spline transfer bar and provided with an oil shedding opening communicated with a spline meshing point.The lubrication structure can lubricate the splines on the transfer bar at the high rotating speed and high loading condition, and the working reliability of the transfer bar is improved; in addition, the oil distribution sleeve is designed, the effect that the single nozzle distributes oil to lubricate the splines at the two ends is achieved, the space is saved, machining is convenient, and the structure can be widely applied to lubrication of other spline transfer bars.

Description

A kind of lubrication system of spline drived bar
Technical field
The present invention relates to a kind of lubrication system, the lubrication system of especially a kind of spline drived bar.
Background technology
Spline is a kind of structure being usually used on drive link transmitting power, owing to its length of action is long, inside and outside spline cooperates, directly lubrication is extremely difficult, at present frequently with lubricating system be mainly the fog lubrication suitable in the slow-speed of revolution, low load working condition, or arrange the direct lubricating system of oilhole on spline, but this structure can affect spline intensity, inapplicable high load conditions.Therefore but for the spline drived of high rotating speed, big load, above-mentioned lubricating system cannot meet its functional reliability.
Summary of the invention
It is an object of the invention to the lubrication system by providing a kind of spline drived bar, it is possible to meet the lubrication of high rotating speed, top load drive link upper spline, thus ensureing spline drived bar smooth running, improving functional reliability.
The technical scheme is that, the lubrication system of spline drived bar includes spline drived bar, nozzle, point oil jacket, closure;Described spline drived bar is hollow structure, and two ends, with external splines, connect the power input with internal spline and the power take-off with internal spline respectively, and nozzle is fixed, and is positioned at one end of spline drived bar, and the jet of nozzle is just to spending inside strong drive link;Dividing oil jacket is annular, it is arranged on drive link endoporus, and it is positioned at the side that nozzle is installed, oil jacket is divided to be internally provided with interlayer, described interlayer is provided with a point hydraulic fluid port, point hydraulic fluid port is arranged on outside the centre of gyration spending strong drive link, and is positioned at the oil spout position of nozzle, and what point oil jacket is provided with between interlayer with oiler the spline engagement point with point oil jacket installation end communicates gets rid of hydraulic fluid port;Described closure is arranged on the other end of spline drived bar, and closes internal for spline drived bar, closure is provided with and gets rid of hydraulic fluid port with the spline engagement point blocking installation end communicates.The described hydraulic fluid port that gets rid of is 4.
In use, the lubricating oil of nozzle ejection enters into a point oil jacket to the present invention, and due to the stop of interlayer, lubricating oil remains in point oil jacket, and enters into spline engagement place by getting rid of hydraulic fluid port, is lubricated;Simultaneously as the rotation of drive link, when a point hydraulic fluid port is positioned at lubricating oil eject position, a part enters inside spline drived lever through undue hydraulic fluid port, and stream, to the other end, under the influence of centrifugal force, is lubricated by getting rid of the hydraulic fluid port spline engagement place to the other end.Present invention accomplishes the lubrication of high rotating speed, top load condition underdrive bar upper spline, improve drive link functional reliability;Additionally design point oil jacket, reaches single nozzle and divides the effect of oil lubrication two ends spline, namely save space, again convenient processing, and this class formation can be widely applied to other spline drived bar lubrication.
Accompanying drawing explanation
Fig. 1 is the lubrication system of spline drived bar.
Detailed description of the invention
As it can be seen, the lubrication system of spline drived bar includes spline drived bar 1, nozzle 6, point oil jacket 2, closure 3;Described spline drived bar 1 is hollow structure, two ends, with external splines, connect the power input 4 with internal spline and the power take-off 5 with internal spline respectively, and nozzle 6 is fixed, and it being positioned at one end of spline drived bar 1, the jet of nozzle 6 is just internal to spending strong drive link 1;Dividing oil jacket 2 is annular, it is arranged on drive link 1 endoporus, and it is positioned at the side that nozzle 6 is installed, oil jacket 2 is divided to be internally provided with interlayer, described interlayer is provided with point hydraulic fluid port 9, point hydraulic fluid port 9 is arranged on outside the centre of gyration spending strong drive link 1, and is positioned at the oil spout position of nozzle 6, and what point oil jacket 2 is provided with between interlayer with oiler the spline engagement point with point oil jacket installation end communicates gets rid of hydraulic fluid port 7;Described closure 3 is arranged on the other ends of spline drived bar 1, and closes internal for spline drived bar 1, closure 3 is provided with and gets rid of hydraulic fluid port 8 with the spline engagement point blocking installation end communicates.The hydraulic fluid port 8 that gets rid of got rid of in hydraulic fluid port 7 and closure on described point oil jacket is 4.
