Description
The utility model relates to a kind of device that gear-box loads grinding and performance test that is used for.
The purpose that gear-box is loaded is: (1) gear grinding.Interaction by lapping-in agent and gear improves the contact precision of gear, reduces the performance test of mismachining tolerance to influence (2) gear of transmission quality.Obtain the technical parameter such as transmission efficiency, intensity, noise of gear by test.But there is following defective respectively in existing gear loading technique, has limited this The Application of Technology scope, the particularly application on many specifications, high power gearbox.
1, machinery or fluid power moment of resistance formula: principle is by being connected mechanical brake device or the fluid power wasted work device on the gear-box output, the mechanical energy of input is converted to thermal energy consumption fall, and energy utilizes unreasonable, is not suitable for the loading of high power gearbox.
2, torque arm sealing torque type: principle is with torque arm and connecting axle identical two gear-boxes to be formed the sealing transmission system, produces the loading moment that strain constitutes gear-box by making torque arm artificially.This mode reasonable energy utilization, but need the mated gear case to load, and also frock is poor for applicability, so be unsuitable for loading single and many specifications gear-box.
3, motor generator Feedback of Power formula: its principle is the major part of motor from the electric energy of gear-box input input, generator by output feeds back to motor or electrical network again, electric energy is fully used, this mode needs complicated distribution system, applies to it and causes difficulty.
Task of the present utility model is to provide a kind of can solve many specifications better, the high power gearbox loading is ground and the device of performance test.
Above-mentioned task be achieved in that this device mainly by drive part, loading section, control section, metering section form, the drive part of gear-box is made up of oil motor, power oil pump, motor or oil motor, motor.Loading section is made of oil pump.Oil motor is connected with the power shaft or the output shaft of gear-box respectively with oil pump.Oil circuit between oil motor and oil pump is interconnected.Pressure oil in the oil circuit can act on oil motor and oil pump simultaneously, constitutes the driving moment of oil motor and the running resistance square of oil pump respectively.For guarantee that gear-box can run well under loading environment, the driving moment on the tooth axle that is connected with oil motor is greater than the running resistance square on the tooth axle that is connected with oil pump.When oil motor drives the running of (motor is also participated in driving sometimes) gear-box, oil pump also is driven and pressure oil output, and the major part of this pressure oil enters the driving force that oil motor becomes gear-box, forms mechanical energy and hydraulic pressure and can transform the system of recycling mutually.Except that the loss of each efficiency of element, the major part of the energy of importing is recycled in this system, and add load and exist with the form of system's internal force, need not the peripheral hardware torque balance device.The foundation of system's internal pressure mainly realizes in the following manner: 1, by the power oil pump in the drive part to the direct input pressure oil of system.2, make oil pump delivery flow Q1 greater than the needed flow Q2 of oil motor by adjusting, force system pressure to raise, and unnecessary flow Q3 discharges through the overflow element, the effect of the motor in the drive part is to system's input mechanical energy, system is started and set up system pressure, replenish the energy that each element lost in the system in the loading procedure simultaneously.
Consider the needs that different size, different speed ratio gear case are loaded, gear-box tooth axle is connected with oil pump and oil motor, can adopt band transmission, tooth transmission, universal drive shaft or common shaft coupling etc. multi-form, that oil motor in the device and oil pump also can be selected metered dose as required or variable type.
During use,, select adjustment drive part, loading section, each component parameters of control section to make it to satisfy and load requirement at first according to the loading moment of gear-box, the speed ratio and the loading velocity of loading system (comprising gear-box and transmission joint).Actuating motor then, after in system, setting up required pressure, when gear-box is forced to turn round under oil motor driving moment (moment that also comprises motor sometimes) effect, make the oil pump running by the tooth axle that links to each other with oil pump, mechanical energy is changed into the hydraulic pressure energy again through oil pump, become the part of oil motor driving force, thereby realize the recycling of portion of energy.Because there is loss in efficiency in each element in the system, can not realize the recycling of input energy 100%, the energy that its loss part is provided by motor is replenished.
Compared with the prior art, the energy utilization of said system is tending towards reasonable, consumed power is few, and owing to made full use of the characteristics that hydraulic system parameters is convenient to regulate, can realize that high pulling torque and hydraulic pressure can transmit by flexible pipe, make it can between the input of gear-box, output shaft, form the moment closed system, be more suitable for bearing the loading tasks of many specifications, high power gearbox, application value is widely arranged.
Below in conjunction with embodiment this technology is described in further detail.
During work, at first, select each component parameters of Adjustment System, make it to satisfy loading requirement, and make oil pump 4 delivery flow Q1 be slightly larger than 1 receptible flow Q2 of oil motor according to the loading moment of gear-box, loading system transmission loading velocity when.Behind the actuating motor 3, power oil pump 2 flows system's inner fluid and promotes gear-box by oil motor 1 and drives oil pump 4 running pump oil.Because the flow Q1 of oil pump 4 greater than the flow Q2 of oil motor, forces the oil pressure in the oil circuit between oil pump 4 and the power oil pump 2 to be elevated to the setting pressure P1 of overflow valve 5, unnecessary flow Q3 is through overflow valve 5 oil sump tanks.Power oil pump 2 plays a supercharging in system; make oil pump 4 output oil pressure P1 be elevated to oil motor import oil pressure P2; the pressure that produces through each element with compensation fluid fall and the driving moment of the oil motor 1 that guarantees to constitute by Q2P2 greater than the running resistance square of the oil pump 4 that constitutes by Q1P1; realize the loading running of gear-box; the effect of overflow valve 6 is that control P2 is no more than predetermined value, plays the safeguard protection effect.
In this system, the loading moment of gear-box depends on the discharge capacity q1 and the pressure p 1 of oil pump 4, and running speed is then by the flow-control of power oil pump 2, and the discharge capacity q2 of oil motor 1 approximates the discharge capacity q1 of oil pump 4 and the product of loading system speed ratio 1.Therefore, as long as according to the situation of different gear-boxes, choose reasonable, adjust above parameter, can satisfy plurality of specifications, the loading of different capacity and speed ratio gear case needs.
In above-mentioned loading operation process, add the lapping-in agent at the wheel between cog, just can finish the loading of gear-box grinds, and it is on-stream by data such as monitoring analysis system pressure, flow, moments of torsion, then can obtain the transmission efficiency of gear, vibration, technical parameters such as noise are finished the performance test work of gear-box.
Embodiment 4 is as Fig. 4.As different from Example 1, the drive part of this scheme is made up of oil motor 1 and motor 3, be characterized in that this scheme adopts a double-axis motor 3, oil pump 4 oil-ins are connected with fuel tank, an axle of motor 3 is connected with oil motor 1, another root axle is connected with gear-box tooth axle, is connected to overflow valve 5 between oil pump 4 and the oil motor 1.
Adjust oil motor 1, oil pump 4, overflow valve 5 etc. before using, make each component parameters satisfy the needs of loading moment and gear-box speed ratio, make the flow Q1 of oil pump 4 simultaneously, be slightly larger than the flow Q2 of oil motor 1.Behind the actuating motor 3, in the gear-box running, oil pump 4 beginning pump oil, oil motor 1 entry into service, because Q1＞Q2 just forces system pressure to be elevated to the setting pressure P of overflow valve 5, unnecessary flow Q3 is through overflow valve 5 oil sump tanks.Q2P acts on the driving moment that oil motor 1 and motor 3 constitute gear-box together, and Q1P acts on oil pump 4, becomes the running resistance square of gear-box, reaches the purpose that gear-box is loaded.System starts and each efficiency of element loss institute energy requirement of replenishment system is directly provided by motor 3.Adopt this scheme to have simplified equipment, but to be not easy to carry out the adjusting of loading velocity less with a table oil pump.
