Description
Technical field
The utility model is related to speed changer spindle technology field, specifically, is a kind of self-check type self-lubricating power transmission shaft.
Background technology
Main shaft refers to the axle for receiving power from engine or motor and it being transmitted to other parts, is commonly used in speed changer
On.The lubricating system of main shaft is the important component in gear, and its main function, which is supplied with gear, respectively moves
The lubricating oil of friction pair convenient pressure and flow.Use more and set on main shaft the structure design of existing gear lubricating system
The mode of oil leab realizes lubrication.Axle centre drill shaft to main oil gallery, and bearing, gear and clutch etc. are being installed
Corresponding position gets out the radial direction seed oil road communicated with axial lubrication hole.So, end of the lubricating oil through each power transmission shaft enters
Axial main oil gallery, and by some radial direction seed oil roads corresponding bearing, gear and clutch are lubricated, cooled down.
At a high speed rotation it is very big to gear Lubrication Properties, the lubricating oil in main oil gallery by centrifugal action,
It make it that under given lubricating oil pressure the flow of lubrication for flowing into main oil gallery and the outflow of each seed oil road changes, it is possible to
There is the phenomenon that main oil gallery end is located at the seed oil road fuel feeding of end without normal direction, cause final drive element lubrication failure.
Utility model content
In view of this, the utility model provides a kind of self-check type self-lubricating power transmission shaft, and stream is provided with the main oil gallery
Quantity sensor, detection stream enters the flow of lubrication of main oil gallery, and controls the flow and pressure that lubricating oil injects according to the data.Tool
Body technique scheme is as follows：
The different construction section of multiple radiuses is provided with a kind of self-check type self-lubricating power transmission shaft, including axis body, the axis body,
Its key is：Offered along the axis body axial line and offer radial direction on axial main oil gallery, the side wall of the construction section
Seed oil road, the seed oil road is communicated with the main oil gallery, and flow sensor, the flow sensing are provided with the main oil gallery
Device monitors flow of lubrication.
Self-check type self-lubricating power transmission shaft based on said structure design, peripheral control unit can be according to the flow sensor
The flow of lubrication data of detection, the flow and pressure of control external lubrication oil injection, so as to ensure that the main oil gallery of main shaft can
For all seed oil roads fuel feeding, and then guarantee as the axial lubrication of the bearing on axis body, gear and clutch etc.
Hole fuel feeding.
Further, the flow sensor is located between the end of the main oil gallery and last seed oil road.Due to
Lubricating oil viscosity is larger, and the not enough situation of fuel feeding occurs in the end of main oil gallery, so designs, on the one hand can detect in main oil gallery
Lubricating oil injects situation, on the other hand can monitor the oiling conditions of the end of main oil gallery.
In the specific implementation, to ensure that the wire of the flow sensor is not influenceed by lubricating oil, can accurately with
Peripheral control unit is connected, and conduit is additionally provided with the afterbody of the main oil gallery, and the wire of the flow sensor is led described in
Spool is connected with peripheral control unit, and the conduit uses resin material.
Beneficial effect：Simple in construction, effective detection main oil gallery end is to the seed oil road fuel feeding situation positioned at main oil gallery end；
And the data gathered according to flow sensor control the flow and pressure that extraneous lubricating oil injects, it is ensured that the actuated element on main shaft
Lubricating system normally run.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail.
Multiple radiuses are provided with a kind of self-check type self-lubricating power transmission shaft as shown in Figure 1, including axis body 1, the axis body 1
Different construction sections 2, its key is：Axial main oil gallery 3, the side of the construction section 2 are offered along the axial line of axis body 1
The seed oil road 4 of radial direction is offered on wall, the seed oil road 4 is communicated with the main oil gallery 3, and stream is provided with the main oil gallery 3
Quantity sensor 5, the flow sensor 5 monitors flow of lubrication.
Self-check type self-lubricating power transmission shaft based on said structure design, peripheral control unit can be according to the flow sensor
The flow of lubrication data of 5 detections, the flow and pressure of control external lubrication oil injection, so as to ensure the energy of main oil gallery 3 of main shaft
It is enough all fuel feeding of seed oil road 4, and then guarantees the axial direction profit for the bearing on axis body 1, gear and clutch etc.
Lubrication hole fuel feeding.
It can further be seen from figure 1 that the flow sensor 5 be located at the main oil gallery 3 end and last seed oil road 4 it
Between.Because lubricating oil viscosity is larger, the not enough situation of fuel feeding occurs in the end of main oil gallery 3, so designs, on the one hand can detect
Lubricating oil injects situation in main oil gallery 3, on the other hand can monitor the oiling conditions of the end of main oil gallery 3.
In the present embodiment, to ensure that the wire of the flow sensor 5 is not influenceed by lubricating oil, can accurately with
Peripheral control unit is connected, and is additionally provided with conduit 6 in the afterbody of the main oil gallery 3, the wire 7 of the flow sensor 5 is through institute
State conduit 6 with peripheral control unit to be connected, the conduit 6 uses resin material.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
