Abstract
The invention provides a novel flexible coupling of a small engine dynamometer, which consists of a positioning plate, a coupling bracket, a dynamometer connecting disc, a protective plate, rollers, spring protective covers and springs. The dynamometer connecting disc and the protective plate are in threaded connection; six grooves are formed in the outer surface periphery of the coupling bracket; the bottom surfaces of the grooves are eccentric circular arc surfaces, and are formed to inner and outer rolling ways of the rollers with the inner surface of the dynamometer connecting disc; and the rollers are evenly distributed in the grooves of the coupling bracket, and are frequently pressed to one narrower ends of the inner and outer rolling ways by spiral springs coated with the spring protective covers so as to tighten the inner and outer rolling ways. Three inclined chutes are formed in a disc, near a flywheel, of the coupling bracket; the end surface of the positioning plate is butted against an engine flywheel boss; and the coupling bracket is in threaded connection with the flywheel by the inclined chutes and the positioning plate. The novel flexible coupling of the small engine dynamometer is compact in structure, can synchronously realize the buffer and vibration reduction effects, can be suitable for rack tests of engines with different model numbers, and is simple and feasible in operation.
Description
Technical field
The present invention relates to a kind of Novel small-sized engine dynamometer flexible connection, do not need flywheel connection set, the engine dynamometer on different model engine flywheel and test-bed is directly coupled together, can slowing down vibration, compact structure, is applicable to the engine performance test of different model.
Background technique
In engine bench test, often need to adopt flexible connection engine flywheel and power measurer to be coupled together, but the flexible connection used at present, when carrying out different model engine rig test, all to change the flywheel connection set corresponding with this engine model, dismounting is more loaded down with trivial details, although and whole flexible connection structure is simple, takes up space larger.
Summary of the invention
The present invention is a kind of Novel small-sized engine dynamometer flexible connection, and the technological scheme that its technical solution problem adopts is: comprise the land for connecting with power measurer, for connect with engine flywheel shaft coupling support, be arranged on roller between power measurer land and shaft coupling support, backplate, spring protecting jacket and in spring protecting jacket for limit roller spring, be arranged on positioning plate between shaft coupling support and engine flywheel.Shaft coupling support comprises the Left-wing Federation's joint support, attachment post and the right shaft coupling support that are made of one; six are furnished with for placing the groove of roller and placing the spring seat of spring along Left-wing Federation's joint support even circumferential; the bottom surface of groove forms the inside and outside raceway of roller in the arc surface of bias and the internal surface of land attachment post; roller is operationally had the spring of spring protecting jacket to press to one end narrow between inside and outside raceway by outside cover; and by inside and outside raceway wedging, right shaft coupling support is evenly arranged three oblique chutes.Positioning plate exterior edge face is circular arc, and the boss abutting against engine flywheel according to this end face realizes certralizing ability, and its through hole can through the boss of engine flywheel, and right shaft coupling support is threaded with engine flywheel through its oblique chute, positioning plate.
The invention has the beneficial effects as follows: when carrying out the stand test of different model motor, only positioning plate and connecting bolt need be moved along the oblique chute on right shaft coupling support, just by the flywheel scyewed joint of positioning plate and different model motor, do not need to change flywheel tie-plate, helical spring also plays the effect of buffer shock-absorbing, total is compact, does not take larger test-bed space, easy to operation.
