Abstract
The invention provides a novel flexible coupling for a small engine dynamometer. The novel flexible coupling is composed of a connecting disk, a guard plate, pin rollers, spring protection jackets, springs, a coupling support and locating plates. The connecting disk and the guard plate are in threaded connection. A plurality of grooves are distributed in circumference in the outer surface of a left coupling support part. The pin rollers can roll between the bottom faces of the grooves and the inner surface of the connecting disk. The springs placed in the spring protection jackets on a spring seat on the inner surface of the connecting disk press and abut the pin rollers to the side faces of the grooves of the left coupling support part according to the pre-tightening force of themselves. The locating plates are moved to slide along oblique sliding grooves of a right coupling support part. The right coupling support part, the locating plates and an engine flywheel are fixed in a threaded connection mode. Power of the engine flywheel is transmitted to the dynamometer through the locating plates, the coupling support, the pin rollers, the springs and the connecting disk. By the adoption of the novel flexible coupling, the buffering and damping effect is good, alignment balance precision is high, the structure is compact, and the coupling can be applied to an engine bench test without a flywheel connection device.
Description
Technical field
The present invention relates to a kind of Novel small-sized engine dynamometer flexible connection, be applicable to mini engine stand test, power measurer and motor are coupled together.
Background technique
In engine rig test, often need engine flywheel and power measurer to be coupled together by flywheel connection set, belt flexible connection, the belt flexible connection used at present, although have good buffer shock-absorbing effect, physical dimension is larger; And because belt has certain pliability, during work, belt flexible connection whipping amplitude is comparatively large, and centering balance quality is not high enough; Secondly, when carrying out the stand test of different model motor, all will change the flywheel connection set corresponding with this engine model, dismounting is more loaded down with trivial details.
Summary of the invention
The present invention is a kind of Novel small-sized engine dynamometer flexible connection, the technological scheme that its technical solution problem adopts is: can realize being directly connected with more accurately elasticity between motor and power measurer, it is characterized in that: by the land 3 with power measurer scyewed joint, backplate 4, shaft coupling support 2, be arranged on the roller 5 between power measurer land 3 and shaft coupling support 2, spring protecting jacket 6, spring 7, the positioning plate 1 be arranged between shaft coupling support 2 and engine flywheel is formed, the power of engine flywheel is through positioning plate 1, shaft coupling support 2, roller 5, spring 7, land 3 passes to power measurer.
Described shaft coupling support 2 comprises the Left-wing Federation joint support 2-1 be made of one, attachment post 2-2 and right shaft coupling support 2-3, even circumferential along Left-wing Federation joint support 2-1 is distributed with several for placing the groove 2-4 of roller 5, the bottom surface of groove 2-4 is in eccentric arc surface, roller 5 can roll between the bottom surface of groove 2-4 and the internal surface of land 3, right shaft coupling support 2-3 is evenly arranged three oblique chute 2-5, be placed on the spring 7 in the spring seat upper spring protecting jacket 6 of land 3 internal surface, according to its pretightening force, roller 5 is pressed against the groove side of Left-wing Federation joint support 2-1.
Described backplate 4 and land 3 are threaded connection, Left-wing Federation joint support 2-1 is clipped in the middle, positioning plate 1 exterior edge face c is circular arc, and the boss abutting against engine flywheel according to this end face c realizes certralizing ability, its through hole 1-2 can through the boss of engine flywheel, running fix plate slides along the oblique chute 2-5 of right shaft coupling support 2-3, the through hole 1-1 of positioning plate 1 and the tapped hole of engine flywheel are aligned, is threaded connection and shaft coupling support 2, positioning plate 1, engine flywheel are fixed together.
The invention has the beneficial effects as follows: the flexible connection that physical dimension is larger can be replaced, there is the effect of buffer shock-absorbing, compact structure, and 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, centering balance quality is higher, do not need flywheel connection set, easy to operation.
