21。
The operation principle of oil filling measuring device is：
With reference to Fig. 1, operation torque providing unit 1 is worked, and moment of torsion is provided to axle to be measured.Main reducing gear in speed changer is revolving
Gearbox lubrication liquid is stirred during turning, beaten on the oil duct of gear box casing 3, is collected lubricating oil in axle by oil guide groove
At bearing hole, lubricating oil is oriented to axle to be measured, lubricant effect is played to axle to be measured.Lubricating oil on axle to be measured can be through collection
Hydraulic fluid port 22 flows to flow pump 5 and lubricating oil measuring appliance 6, and is back to axle to be measured from oil filler 21, forms loop.
Flow pump 5 is opened, the lubricating oil oil mass flowed in lubricating oil measuring appliance 6 gradually increases.Adjust the stream of flow pump 5
Amount so that the flow of lubrication that lubricating oil measuring appliance 6 is flowed to from flow pump 5 gradually tends towards stability, and loop is in dynamic equilibrium shape
State.Lubricating oil level stability in dynamic balance state, lubricating oil measuring appliance 6 is in a target location, lubricating oil measuring appliance 6
Lubricating oil can meet oil filling amount needed for axle to be measured lubrication just.Now, read in the lubricating oil measuring appliance 6 and moisten
The numerical value of the target location of lubricating oil, the numerical value are oil filling amount needed for axle to be measured.
Gearbox lubrication experimental rig of the present invention can be in quantitative measurment gearbox all axles to be measured needed for lubricating oil
Adding amount.By adjusting torque providing unit 1 to export different moments of torsion and rotating speed, difference of the axle to be measured under each gear is corresponded to
Oil filling amount.For measuring the different oils adding amount under each gear corresponding to different rotating speeds, obtain each and treat
Survey oil filling amount of the axle needed under different stalls.Consider oil filling amount needed for all axles to be measured, such as examine
Consider the axles to be measured such as odd number shelves input shaft, even gear input shaft, transmission output shaft, differential bearing each required oil filling
Amount, finally gives oil filling amount optimal solution in gearbox.
On the one hand can effectively per a gearbox optimal oil filling amount, adding amount suitably can be with for quantitative analysis
Churning loss is effectively reduced, improves lubricating efficiency.On the other hand the internal oil channel of gear box casing 3 and oil guide groove can also be instructed accordingly
Design.For example, the subsequent development stage can by constantly adjusting the flow of flow pump 5, reduce gearbox entirety lubricating oil plus
Fluence, spin loss is reduced, improve overall efficiency.Accordingly, obtained flow can be measured according to flow pump 5, speed change can be adjusted
The size of the internal oil channel of tank shell 3 and oil guide groove, to adjust the flow of lubrication that axle to be measured is flowed to from oil duct and oil guide groove.
This gearbox lubrication experimental rig it is workable, experiment is accurate, reliable, efficiency high.And this speed changer tries
Experiment device simple structure, it is sturdy and durable, it is easy to maintenance.
Torque providing unit 1 can be motor, and motor is used for simulated engine, changes the difference of motor
Rotating speed can adjust the moment of torsion for being transferred to gearbox 2.Motor carries torque-speed instrument 10, and torque-speed instrument 10 can be used
Carry out the accurate moment of torsion and speed for adjusting motor output.

Second oil pipe 8 connection lubricating oil measuring appliance 6.First oil pipe 7 connects oil collect port 22, the second oil pipe 8 connection oil filler 21 so that profit
Lubricating oil flows to oil filler 21 from oil collect port 22, the first oil pipe 7, flow pump 5, the oil pipe 8 of lubricating oil measuring appliance 6 and second successively, and
Flow back to axle to be measured.
Reference picture 2, check valve 9 is connected between flow pump 5 and lubricating oil measuring appliance 6, check valve 9 is used for：Make lubrication
Oil flows to lubricating oil measuring appliance 6 from flow pump 5.Check valve 9 is used for preventing lubricating oil from passing back into flow pump from lubricating oil measuring appliance 6
5, the measurement accuracy of oil filling amount in gearbox can be lifted.
Lubricating oil measuring appliance 6 is measuring cup, and measuring cup can be cylindric.Or lubricating oil measuring appliance 6 can be up big and down small
Round estrade it is round table-like.Graduation mark is carved with measuring cup, during oil filling measurement, when lubricating oil is stable extremely in measuring cup
During one graduation mark, scale value can be read immediately, and then obtains oil filling amount.This causes oil filling measuring device
It is simple in construction.
Reference picture 2 and Fig. 3, entrance 61 and outlet 62 are provided with the side wall 60 of measuring cup, flow pump 5 passes through the connection amount of entrance 61
Cup, second oil pipe 8 of the connection of outlet 62.
The protuberance 64 positioned at bottom wall 63 is provided with measuring cup, the effect of protuberance 64 is：When lubricating oil oil mass is less,
Because protuberance 64 takes space in more measuring cup, protuberance 64 can make in measuring cup that lubricating oil liquid level is higher, and level change is easy
Discover, it can be ensured that the data of reading are accurate.
Protuberance 64 includes：By in measuring cup to outside measuring cup and at least two sub- protuberances that linearly A arranges successively
640, the rectilinear direction is perpendicular to bottom wall 63.In the two neighboring sub- protuberance 640 of linearly A arrangements, the bottom of close to
The sub- protuberance 640 of wall 63 perpendicular to rectilinear direction sectional area, less than away from bottom wall 63 sub- protuberance 640 perpendicular to straight line
Direction A sectional area.
For example, protuberance 64 includes three sub- protuberances 640 that linearly A arranges successively.On the one hand, three sons are dashed forward
Going out portion 640 can make that lubricating oil liquid level is higher in measuring cup, and level change is easily discovered.On the other hand, due to three sub- protuberances
Linearly for A to being gradually reduced outside measuring cup out of measuring cup, space is increasing in measuring cup, can to press for 640 sectional area
For power with regard to increasing, this plays certain pressure maintaining effect to lubricating oil in measuring cup, keeps liquid level stabilizing.
Wherein, there is step 641 between two neighboring sub- protuberance 640., can be to the edge of protuberance 64 in manufacturing process
Rectilinear direction A carries out punching press, forms step 641, manufacturing process simple possible.As a kind of variation, two neighboring son is prominent
Portion can be seamlessly transitted with linearly A.
Sub- protuberance 640 is cylindric, and the axis parallel of sub- protuberance 640 is in rectilinear direction A.Columned son is prominent
The controllability of portion 640 is high, is easier to realize.
All sub- protuberances 640 are coaxially disposed, and this can make the manufacturing process of protuberance 64 have more controllability, manufacture work
Skill is simpler.
Although present disclosure is as above, the present invention is not limited to this.Any those skilled in the art, this is not being departed from
In the spirit and scope of invention, it can make various changes or modifications, therefore protection scope of the present invention should be with claim institute
The scope of restriction is defined.
