The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs.
As shown in fig. 1 and 2, the embodiment provides a flywheel dismounting device of an air compressor, which comprises a fixing plate 1, a first bolt 2, a second bolt 3 and a jackscrew 4. The fixed plate 1 is provided with two first through holes 5, and the two first through holes 5 are respectively close to two ends of the fixed plate 1. The center distance between the two first through holes 5 is equal to the center distance between any two opposite second through holes 6 in the middle of the flywheel 8, and the first bolts 2 and the second bolts 3 penetrate through the two through holes in a one-to-one correspondence manner, so that the first bolts 2 and the second bolts 3 respectively correspond to the two opposite second through holes 6 in the middle of the flywheel 8. The first bolt 2 and the second bolt 3 are respectively provided with at least four locknuts 7, when the locknuts are connected with the flywheel 8, at least two locknuts 7 are positioned on one side of the first through hole 5, at least two locknuts 7 are positioned on one side of the second through hole 6, namely, the first bolt 2 and the second bolt 3 are locked with the flywheel 8 and the fixed plate 1 by adopting the four locknuts 7.
The middle part at fixed plate 1 is equipped with rotatable jackscrew 4, first bolt 2 and second bolt 3 all are perpendicular and all lie in on a straight line with fixed plate 1. One end of the jackscrew 4 is provided with a cushion body 9, the cushion body 9 is in the shape of a disc, and the diameter of the cushion body 9 is smaller than the diameter of the outer end of the crankshaft of the air compressor. The jackscrew 4 is tightly propped against the outer end surface of the crankshaft with the pad body 9, so that the contact area is increased, and the eccentric problem caused by overlarge stress of the jackscrew 4 is solved. A hexagonal screw head 10 is arranged at the other end of the jackscrew 4. The hexagonal screw head 10 can be matched with a conventional wrench, has low requirement on tools for rotation and is convenient to use.
