Abstract
The invention discloses a novel long shaft coupler which is connected with a through wall in an NVH (noise, vibration and harshness) test bed design. The novel long shaft coupler can transmit large torque at a long distance and is wide in speed regulation range; the novel long shaft coupler is formed by assembling a shaft coupler receiving disk 1 (which is as shown in a figure), cone pins 2 (which are as shown in the figure) and a shaft coupler steel pipe 3 (which is as shown in the figure); certain taper is formed between the shaft coupler receiving disk and the steel pipe, so that assembling and positioning can be guaranteed and facilitated; by radial cone pin connection and by the arrangement of a bolt group (4, 5 and 6) (which is as shown in the figure), the axial pretightening force is increased. According to the novel long shaft coupler, the shortcomings in the prior art are overcome, and the transmission torque can be effectively enhanced.
Description
Technical field
The present invention relates to a kind of long-shaft type coupling, particularly relate to a kind of Novel major axis coupling for NVH test stand.
Background technique
Long shaft coupler is applicable to longer-distance transmission of power on bed stand, is usually used in the power transmission of laboratory test stand and outdoor test stand in NVH Test-bed Design.Owing to having higher accuracy of alignment requirement for stand in NVH test, operating condition of test has strict requirement to the torque range of long shaft coupler and speed range, the high speed operating conditions under especially large torque simultaneously.
Current long-shaft type coupling mainly contains Rzeppa type, universal joint and carbon fiber tubular type three kinds.Universal joint or Rzeppa type long shaft coupler cannot meet the high speed operating mode under large torque; And carbon fiber tubular type long shaft coupler is mainly improved in material, it can meet above working condition requirement, but price is too expensive.Therefore, based on the above, this patent adopts common material, devises aly can meet the required working condition requirement of NVH test, the long-shaft type coupling of less expensive simultaneously.The conical surface that this long shaft coupler is connect between dish 1 and coupling steel pipe 3 by coupling connects, and increase radial taper pin 2 and connect, to meet the requirement of transmitting large torque, simultaneously by the selection of diameter of steel tube and the control of processing technology, expand the speed range that it is suitable for.
The structure of the uniqueness that long-shaft type coupling involved in the present invention adopts can ensure long distance transmitting large torque, not only has very high accuracy of alignment and rigidity, also has wider speed range.Meanwhile, this long-shaft type coupling also has comparatively economic raw material and processing technology.
Summary of the invention
The object of the invention is to overcome prior art Problems existing, a kind of Novel major axis coupling for NVH test stand is provided.
For realizing object of the present invention, the invention provides a kind of Novel major axis coupling for NVH test stand, the structure of this long shaft coupler mainly comprises: coupling connects dish 1, taper pin 2, coupling steel pipe 3 and bolt group 4,5,6.Coupling connects between dish and steel pipe has certain tapering can ensure to be convenient to assembling and positioning, is connected and increase axial pre tightening force by bolt group by radial taper pin.
Further improvement of the present invention is, coupling connects between dish 1 with coupling steel pipe 3 and adopts adopting conical surface interference to coordinate, and increases radial taper pin, to ensure high rigidity and the centering of coupling, and transmits larger moment of torsion.
Further improvement of the present invention is, long-shaft type coupling is with wall-punching axis structural type, links the critical component of indoor stand and outdoor stand.
Further improvement of the present invention is, Elastic medium can be installed to increase the collectivity damping property of this long shaft coupler in the two ends, left and right of long shaft coupler.
The invention has the beneficial effects as follows: it is simple that long shaft coupler has processing technology, installation centering is simple, easy to maintenance, and transmitting torque is large, distance, and speed range is wide, good reliability, low cost and other advantages.Meet the requirement of NVH test stand accuracy of alignment, meet the requirement of operating condition of test to the torque and rotational speed scope of long shaft coupler, the high speed operating conditions under especially large torque simultaneously.

Embodiment
Below better embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
First, by the conical surface of face place, coupling steel pipe 3 two ends processing certain distance; Connect on dish 1 at coupling, be processed into and the conical surface of coupling steel pipe 3 with tapering with the fitting surface of coupling steel pipe 3; Then, equipped coupling steel pipe 3 and coupling connect dish 1; Connect the parts of dish 1 for the coupling steel pipe 3 after being equipped with and coupling, choose suitable position in connecting part and join and bore radial taper pin-hole; Corresponding taper pin is installed, and pre-tightening apparatus (selecting bolt group pre-tightening apparatus herein) is installed on taper pin; Finally, carry out dynamic balancing for this long shaft coupler to check and loading test.
On NVH test-bed, long-shaft type coupling is with wall-punching axis structural type, the key components and parts of stand and outdoor stand in junction chamber.Compensation rate when Elastic medium can be installed to increase the integral damping of this long shaft coupler and to install centering in its two ends, left and right.Then the component such as connecting sensor, bearing support, power measurer are with transmitting torque and rotating speed.
Above mode of execution is only for illustrating technical conceive of the present invention and feature; its object is to allow person skilled in the art understand content of the present invention and to be implemented; can not limit the scope of the invention with this, all equivalences done according to Spirit Essence of the present invention change or modification is all encompassed in protection scope of the present invention.
