Description
Technical field
The utility model belongs to mechanical engineering technical field, relates generally to a kind of big load pinion gear bearing test gear train.
Background technology
Big load pinion gear bearing test gear train is applied to the pinion gear bearing tester, in pinion gear bearing application, have sizable gap the serviceable life of the serviceable life of state's inner bearing and foreign same type bearing, but the price of foreign same type bearing is also very expensive.Be to cooperate the development of wandering star gear-bearing, the factor of analyzing influence bearing performance improves its serviceable life, with regard to simulating the actual applying working condition of pinion gear bearing in the planet gear drive it is tested, and this structure is at above-mentioned and design.The condition of work that pinion gear bearing and those are used for the bearing of general industrial environment has very big difference,, its special condition of work is arranged here:
1. process the cogged gear teeth on the bearing outer ring, the outer ring rotates, and inner ring does not rotate with respect to the outer ring;
The suffered acting force of bearing outer ring be in the planetary gear mechanism with the fixedly central wheel of internal teeth of its tooth mesh and fixedly the external tooth centre wheel to its acting force and the synthesis of the centrifugal force of generation during the toothed disc rotation;
3. use syntholube lubricated, at a high speed, condition such as high temperature.
This bearing comes assumed (specified) load by bearing a pure radial force when design.When plain shaft is made test, if outer ring rotation, inner ring are fixed, then radial force can load by inner ring, if the outer ring is fixed, the inner ring rotation, then radial force can load by the outer ring, and so this inner ring is fixed, outer ring rotation and what be shaped on that the special bearing of the straight spur gear gear teeth at first will consider when the design experiment machine is exactly how pure radial force to be added on this test bearing.The gear of setting on this bearing outer ring when analyzing and calculating the stressing conditions of this paper indication test bearing is as the idle pulley in the fixed shaft gear train, if the planetary gear in the cyclic train then need be reduced to the idle pulley in the fixed shaft gear train.
Inner ring did not rotate when test bearing used in reality, the straight spur gear and the mating gear engaged transmission of outer ring be stressed, and according to the setting of front, the gear on the test bearing outer ring is the idle pulley in the fixed shaft gear train, all has gear to be engaged with on its both sides.In testing machine, test the shaft strength situation as shown in Figure 1 so.Test bearing is subjected to the radial force N of driving wheel effect as shown in Figure 1
1With force of periphery F
1, the follower effect radial force N
2With force of periphery F
2, the bolster effect support reaction F, for simplify calculating, establish N
1=N
2, F
1=F
2, then to make a concerted effort be zero to horizontal direction, vertical direction has F=F
1+ F
2, can think that thus support reaction F can think to be added in the testing machine the equivalent pure radial force on the test bearing, so, how pure radial force is added on this test bearing, this is that we are to be solved in design.
Test bearing is to be contained in the machine of an open power streaming to work under the actual condition, and the peak power that it transmits in this machine multiply by and unevenly reaching hundreds of kilowatts after carrying coefficient.If adopting open power streaming test structure tests, be that the real power that test bearing will transmit is all transmitted by propulsion system, power is delivered to mechanical brake (being energy-dissipating device) at last through driving-chain and produces resistance and realize loading to test bearing.This kind loading method has also consumed the energy of hundreds of kw of power that propulsion system transmitted when test bearing is loaded, wherein a lot of energy have all been made idle work.The test battery bearing will turn round continuously on testing machine and test in thousands of hours, spend hundreds thousand of units.So big power consumption is wasted very much, does not also afford to do.
Summary of the invention
Be to solve the difficult problem in the background technology, the purpose of this utility model is to propose a kind of big load pinion gear bearing test gear train, makes it have efficient height, energy consumption is low, cost is low characteristics.
For finishing foregoing invention purpose the technical solution adopted in the utility model be:
A kind of big load pinion gear bearing test gear train comprises two cover test bearing device and driving-chains; Described every cover test bearing device comprises test bearing, driving wheel and follower; Link to each other by driving-chain between the described two cover test bearing devices, described driving-chain comprises positive coupling and torque loader; Promptly the driving wheel in the first cover test bearing device links to each other with second engaged wheel that overlaps in the test bearing device by first positive coupling, torque loader, second positive coupling, constitute type closed power flow test drive mechanism, the motor that friction force in the promising driving-chain provides power is set.
A kind of big load pinion gear bearing test gear train that the utility model proposes, motor only provides the power that friction force consumed in the driving-chain and test bearing is not loaded in this kind structure, loading is provided by the torque loader in the gear train, the motor power (output) value only is 37kW, 1/10th of the just open power streaming of the electric energy of its consumption test unit version, corresponding expense also only be its 1/10th, have efficient height, energy consumption is low, cost is low characteristics.
