The swinging load testing apparatus is characterized in that the gear device, namely a transmission sample, is installed on bracket, that the output end of the transmission sample is fixed on a bent board, that the input end of the transmission sample is driven by a swing loader, that the gear device is connected with a swing shaft of the swing loader through a rotating speed and torque sensor, that the swing loader is a hollow cylinder, that gas or liquid inlet and outlets are disposed on the wall of the hollow cylinder and are used for injecting gas or liquid, that a swing shaft is disposed on the center of the hollow cylinder, that blades are fixed on the swing shaft, that a limiting baffle plate is disposed on the inner wall of the hollow cylinder and is used for limiting the swinging of the blades, that the gas or liquid inlet and outlets are provided with reversing valves, and that the torque sensor is connected with a measurement and control system and is used for control the reversal of the reversing valves. The swinging load testing apparatus uses a simple method and has an obvious effect, short test time, low investment, a few occupied places and an obvious energy saving effect (the driving power of the swinging load testing apparatus is just one fifth to one fourth of those of an electrically-closed test stand and an mechanically-closed test stand).
Description
Technical field
The utility model relates to a kind of equipment of toothed gearing test, is specially a kind of toothed gearing swing type load test equipment.Toothed gearing comprises the assembly products such as variator.
Background technology
Above-mentioned rig for testing is detected in Russia, and the German ZF successively introducing for many years in my company, in the variator technology of Japan Isuzu Motors and U.S. Bo Ge Warner producer, did not meet the test method in this kind of transmission assembly stand life-span.The transmission assembly stand test on lifetime that we met is all to use traditional test method, that is: be all at transmission input shaft by direct motor drive, load with loader at output shaft, the method for operation is to rotate.Although the test specification of various countries requires at each gear rotating speed height, torque and the duration of runs are upper different, with this simulation experiment method be consistent.And this new test method does not require variator running, only require that variator repeatedly swings under positive and negative torsional interaction.This point has essential difference in test method.My company is at designed, designed with after having developed swing type load test equipment, in Russia's outlet transmission assembly checking business, and first Application swing type load test method and test unit at home.This experimental technique has obtained the Russian expert's of manufacturer accreditation, exports Russian BC255 variator and swing load test specification and formally included in the company standard of my company.
Summary of the invention
The utility model provides a kind of toothed gearing swing type load testing machine, it is characterized in that:
Toothed gearing is that variator sample case is rack-mount, and the output terminal of variator sample case is fixed on bent plate, drive by swinging loader at input end,
Toothed gearing is connected with the axis of swing that swings loader by torque and speed sensors, and swinging loader outside is a hollow cylinder; The import and export of gas or liquid are located on the wall of this hollow cylinder for injecting gas or liquid, in the middle of hollow cylinder, are axis of swing, are fixed with blade on axis of swing, and the inwall of this hollow cylinder is provided with postive stop baffle for limiting the swing of blade; The import and export of gas or liquid are provided with reversal valve, and torque sensor is connected with TT&C system for controlling reversal valve commutation.
Further, blade is two.
Further, at swing loader output terminal, index dial and pivot angle pointer are housed, at the edge of index dial, position transducer are housed, whether normally carry out to monitor swing test.
This rig for testing is compared with traditional, have that method is simple, successful, test period short (than classic method few 18%～68%) and rig for testing small investment and occupation of land little (for traditional experiment platform takes up an area 1/2), save electric energy significantly (driving power be only electricity seal and mechanical close testing table 1/5～1/4) advantage, be worthy to be popularized very much.

Embodiment
Toothed gearing is that variator sample case 8 is arranged on support 7, the output terminal of variator sample case 8 is fixed on bent plate 1, drive by swinging loader 2 at input end, carry out the continuously swing loading procedure of forward → oppositely → forward, the general reversed load of its magnitude of load is nominal torque, forward load is two times of nominal torques, and hunting frequency is per minute 30 times～60 times.Pendulum angle is determined by the system rigidity of variator sample case (8), can be drawn by test.Wobble cycle number of times be 1000～100000 times not etc., depending on the request for utilization of the each gear regulation of making an appraisal.
The swing loader 2 of rig for testing is moving by electricity-liquid or electricity-gas drive, rotating vane 15 in cylinder body 13, the number of blade can be selected 1～3 according to the requirement of angle of oscillation size and loading moment of torsion, modal is to select 2 (as shown in Figure 2), in the time that (the first import 11, the second import 17) is liquid (or gas) import, promote two blades and swing clockwise, now (the first outlet 12, the second outlet 18) is the outlet of liquid (or gas); Between axis of swing and variator sample case 8 input ends, torque sensor 6 has been installed, in the time that torque value reaches setting value, TT&C system 5. is just sent ratio (or servo) the reversal valve commutation of signal by drive system, and now import becomes outlet; Outlet becomes import.Two blades become counter-clockwise swing.In the time that torque value reaches the setting value of another side; reversal valve is just according to the action that once commutates again of the signal that transmits; swing down so and so forth; when every forward → oppositely → forward swings one time; the TT&C system of equipment just records a cyclic process automatically; until complete the cycle index of regulation, rig for testing is auto stop just.Then change a gears and carry out the swing test of next round.
At swing loader output terminal, pendulum angle indicating device is housed, comprises that index dial 3(is containing position transducer) and pivot angle pointer 4, on the edge of pendulum angle index dial, position transducer is housed, whether normally carry out to monitor swing test.
