Abstract
The invention relates to a torque test device which comprises a torque test shaft, a reference shaft, and a locating pin. The torque test shaft and the reference shaft which are hollow shafts are mounted coaxially, the reference shaft is sleeved with the torque test shaft, one end of the torque test shaft and one end of the reference shaft are processed with rectangular gear teeth which are with the same number and are distributed evenly, the two kinds of mounted gear teeth are staggered, and gaps are reserved between the adjacent gear teeth; the other end of the torque test shaft is in interference fit with the other end of the reference shaft, the other end of the torque test shaft and the other end of the reference shaft are provided with locating pins, one end of the torque test shaft is connected with a power input end through an elastic membrane disc, and the other end of the torque test shaft is connected with an output gear through a splined sleeve. According to the torque test device, the problem of welding deformation is solved, buffer and vibration absorbing abilities are good, displacement in the axial direction, in the radial direction and in the angular direction caused by manufacture errors, installation errors, deformation after bearing the weight, and the influence of the temperature and the like is well compensated; the torque test device has the advantages of being easy to process, assemble, dismount and maintain.
Description
Technical field
The present invention relates to a kind of instrument measuring torsional vibration, for measuring aeromotor line shaft output torque value.
Background technology
Output power is the fundamental performance parameter of engine, by measuring rotating speed and torque arithmetic acquisition.At aviation field, instrument measuring torsional vibration is set sky, ground crew can be made to grasp the true output torque of engine in real time, and then corresponding adjustment is made to aircraft, avoid producing great aircraft accident.
The instrument measuring torsional vibration commonly used of current aeromotor primarily of two coaxial hollow shaft sleeves together.Wherein one is axis of reference, and shaft end is circumferentially processed with the equally distributed rectangle gear teeth, sees Fig. 1, and another root axle is that axle is turned round in survey, and its end axis, to being processed with equal number and the equally distributed rectangle gear teeth, is shown in Fig. 2.Above-mentioned two hollow shaft wheel teeth portion bit interleaving engagements form the space of circumference uniform distribution, see Fig. 3.When transmitting torque, by the change in the device measuring spaces such as photoelectric sensor, and then realize the change of moment of torsion.Above-mentioned two tubular shafts do not have the side of the gear teeth to be welded and fixed together.Above-mentioned cover tubular shaft outside is directly connected with middle follower gear by spline, transmits kinematic behavior.
In existing structure, two welding hollow shafts are fixed, due to sweating heat distortion, and the mutual wheel interdental space circumferentially non-uniform Distribution easily caused; Direct employing spline is connected with middle follower gear, and processing difficulties, dismounting are safeguarded inconvenience, the impact etc. well compensated due to foozle, alignment error and temperature variation can not be caused error.
Summary of the invention
The object of this invention is to provide one and there will not be thermal deformation; And there is good buffering, vibration absorption ability, can be good at compensating axial, radial, the angular displacement that the impact etc. due to the distortion after foozle, alignment error, carrying and temperature variation causes; And the instrument measuring torsional vibration of easily processing, easily assembling, quick detachable, easy care.
Technical scheme of the present invention is: instrument measuring torsional vibration structure comprises survey and turns round axle, axis of reference, register pin, axle is turned round in survey and axis of reference is coaxially installed, and be tubular shaft, survey turns round axle sleeve on axis of reference, turn round axle and axis of reference axle head respectively processes equal number and the equally distributed rectangle gear teeth in survey, wherein the gear teeth of axis of reference are radial, survey the gear teeth of turning round axle for axially, two kinds of described gear teeth are interspersed after mounting, leave space between the adjacent gear teeth; Axle is turned round in axis of reference and survey does not have one end of the gear teeth be connected by interference fit and be provided with register pin, and one end that axle is turned round in described survey is connected with power intake by elasticity membranous disc, and the other end is connected with output gear by spline housing.
The present invention surveys and turns round the method that axle and axis of reference adopt slight interference section and register pin, avoids the distortion of welding generation; Register pin by the mode of Combined machining, can ensure that survey is turned round mutual gear teeth when axle is connected with axis of reference and is circumferentially uniformly distributed afterwards; Survey is turned round axle and is adopted very thin elasticity membranous disc to transmit the moment of torsion of driving and driven part, elasticity membranous disc can turn round axle overall processing with survey, simply lightweight without the need to maintenance, easy accessibility, structure, in transmitting torque process, there is good buffering, vibration absorption ability, can compensate very well between two axial lines due to axial, radial and angle skew that the impact etc. of the distortion after foozle, alignment error, carrying and temperature variation causes.Therefore, present invention, avoiding the problem of welding deformation, and there is good buffering, vibration absorption ability, can be good at compensating axial, radial, the angular displacement that the impact etc. due to the distortion after foozle, alignment error, carrying and temperature variation causes; And there is the feature of easy processing, easily assembling, quick detachable, easy care.
