Abstract

The present invention relates to a kind of lubrication system of spline drived bar, including spline drived bar, nozzle, divide oil jacket, closure;Described spline drived bar is hollow structure, and both ends carry external splines, and nozzle is located at one end of spline drived bar, and the jet face of nozzle is spent inside strong drive link;It is annular to divide oil jacket, is internally provided with interlayer, a point hydraulic fluid port is provided with described interlayer, divide to be provided between interlayer and oiler on oil jacket and get rid of hydraulic fluid port;Described closure is provided with installed in the other end of spline drived bar and gets rid of hydraulic fluid port with what spline engagement point communicated.Present invention accomplishes the lubrication of drive link upper spline under the conditions of high rotating speed, top load, drive link functional reliability is improved;Design divides oil jacket in addition, reaches the effect that single nozzle divides oil lubrication both ends spline, that is, saves space, again convenient processing, and this class formation can be widely applied to other spline drived bar lubrications.

Description

A kind of lubrication system of spline drived bar
Technical field
The present invention relates to a kind of lubrication system, especially a kind of lubrication system of spline drived bar.
Background technology
Spline is a kind of structure for being usually used in transmitting power on drive link, and because its length of action is grown, inside and outside spline is mutual Coordinate, directly lubricate it is extremely difficult, at present frequently with lubricating system be mainly suitable for the slow-speed of revolution, low load working condition mist of oil Lubricate, or the direct lubricating system of oilhole is set on spline, but this structure can influence spline intensity, not apply to top load feelings Condition.Therefore but its functional reliability can not be met for high rotating speed, the spline drived of big load, above-mentioned lubricating system.
The content of the invention
The purpose of the present invention is by providing a kind of lubrication system of spline drived bar, can meet high rotating speed, top load The lubrication of drive link upper spline, so as to ensure spline drived bar smooth running, improve functional reliability.
The technical scheme is that the lubrication system of spline drived bar includes spline drived bar, nozzle, divides oil jacket, envelope It is stifled;Described spline drived bar is hollow structure, and both ends carry the power input and band of external splines, respectively connect band internal spline The power take-off of internal spline, nozzle are fixed, and spend strong drive link positioned at one end of spline drived bar, the jet face of nozzle It is internal;It is annular to divide oil jacket, on drive link endoporus, and positioned at the side that nozzle is installed, divides inside oil jacket and sets There is interlayer, a point hydraulic fluid port is provided with described interlayer, divide hydraulic fluid port to be arranged on outside the centre of gyration for spending strong drive link, and be located at nozzle Oil spout position, divide and be provided with what is communicated with dividing the spline engagement of oil jacket installation end point on oil jacket between interlayer and oiler Get rid of hydraulic fluid port;Described closure is arranged on the other end of spline drived bar, and will be closed inside spline drived bar, is provided with closure What the spline engagement point with blocking installation end communicated gets rid of hydraulic fluid port.Described gets rid of hydraulic fluid port as 4.
In the use of the present invention, the lubricating oil that nozzle sprays enters a point oil jacket, due to the stop of interlayer, lubricating oil remains in point In oil jacket, and entered at spline engagement, be lubricated by getting rid of hydraulic fluid port;Simultaneously as the rotation of drive link, when dividing hydraulic fluid port position When lubricating oil eject position, a part enters inside spline drived lever through undue hydraulic fluid port, the other end is flowed to, in the work of centrifugal force Under, by getting rid of hydraulic fluid port to being lubricated at the spline engagement of the other end.Present invention accomplishes passed under the conditions of high rotating speed, top load The lubrication of lever upper spline, improve drive link functional reliability;Design divides oil jacket in addition, reaches single nozzle and is divided to oil lubrication two The effect of spline is held, that is, saves space, again convenient processing, this class formation can be widely applied to other spline drived bar lubrications.
Brief description of the drawings
Fig. 1 is the lubrication system of spline drived bar.
Embodiment
As illustrated, the lubrication system of spline drived bar includes spline drived bar 1, nozzle 6, divides oil jacket 2, closure 3;It is described Spline drived bar 1 be hollow structure, both ends carry external splines, respectively the power input 4 of connect band internal spline with interior flower The power take-off 5 of key, nozzle 6 are fixed, and spend strong drive link positioned at one end of spline drived bar 1, the jet face of nozzle 6 Inside 1;It is annular to divide oil jacket 2, on the endoporus of drive link 1, and positioned at the side that nozzle 6 is installed, is divided inside oil jacket 2 Interlayer is provided with, point hydraulic fluid port 9 is provided with described interlayer, divides hydraulic fluid port 9 to be arranged on outside the centre of gyration for spending strong drive link 1, and Positioned at the oil spout position of nozzle 6, the spline for being provided with and dividing oil jacket installation end on oil jacket 2 between interlayer and oiler is divided to nibble What chalaza communicated gets rid of hydraulic fluid port 7;Described closure 3 is arranged on the other end of spline drived bar 1, and the inside of spline drived bar 1 is sealed Close, be provided with closure 3 and get rid of hydraulic fluid port 8 with what the spline engagement point of closure installation end communicated.Hydraulic fluid port 7 is got rid of in described dividing on oil jacket Hydraulic fluid port 8 is got rid of as 4 with closure.
