Abstract

The invention comprises a motor, a right angle support base, a cylinder elastic support whose both ends are flanges, a hollow shaft, a drive shaft, a L-shaped bracket, a dynamic balancing machine, and a train gauge coated on the cylinder elastic support. In the rotation plane of the crank shaft assembly, along with the orthogonal X,Y directions, simultaneously measuring the unbalance vibration or force signal of the crank shaft assembly running in high speed; after processed by computer, synthesizing the unbalance value along with different directions to form a closed curve graph. The invention also reveals a method thereof.

Description

technical field [0001] The invention relates to a device and method for measuring dynamic balance, in particular to a device for measuring dynamic balance of a crankshaft assembly and a method for measuring the same. Background technique [0002] Motorcycle engine crankshaft assembly includes left crankshaft, right crankshaft, crank pin, connecting rod, piston, piston pin, cylinder liner, left bearing, right bearing and other components. For the dynamic unbalanced force of the engine, it includes not only the unbalanced centrifugal force caused by the rotation of the left and right crankshafts, but also the unbalanced inertial force caused by the high-speed reciprocating motion of the connecting rod and piston along the central axis. Due to the joint action of the above two types of forces, the unbalanced inertial force of the crankshaft assembly on the rotary surface, that is, the X and Y planes, has i The features that vary by variation, i=1, 2,  …. Referring to Figure 6...
