DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0021] See also Figure 1-3A timing fixture for installing a flywheel of a jaw crusher comprises a pressure plate 4, which can be detachably installed on the shaft end of an eccentric shaft 1 to be installed; the interior of the pressure plate 4 is processed with an adjusting screw hole arranged through it, and the interior of the adjusting screw hole is installed with a first adjusting screw 5 by threaded fit, one end of the first adjusting screw 5 is processed with a radially arranged radial threaded hole 12, and the interior of the radial threaded hole 12 is installed with a second adjusting screw 7 by threaded fit, and the end of the second adjusting screw 7 is used for positioning and fitting with a keyway 9 on a pressure plate 3; the pressure plate 3 is fixedly installed on the wheel disc of the flywheel 2. By adopting the above-mentioned fixture, the eccentric shaft and the flywheel can meet the required angle during installation by adjusting the length of the first adjusting screw and the position of the keyway between the second adjusting screw and the flywheel pressure plate according to the installation angle of the flywheel of different models, so as to facilitate the installation and maintenance of the flywheel of the jaw crusher. During installation, in order to ensure the required angle between the eccentric shaft 1 and the flywheel 2, first position and install the pressure plate 3 on the flywheel, then arrange the pressure plate 4 at the end of the eccentric shaft 1, and adjust the second adjusting screw 7 on the pressure plate 4 to position the second adjusting screw 7 and the pressure plate 3. After the positioning is completed, the flywheel is pressed and installed, so that the required angle between the eccentric shaft 1 and the flywheel 2 can be ensured.

[0022] Furthermore, through the threaded cooperation between the first adjusting screw 5 and the adjusting screw hole, the extension length of the first adjusting screw 5 can be conveniently adjusted to adapt to flywheels of different diameters.

[0023] Furthermore, the length of the second adjusting screw 7 can be adjusted by the threaded fit between the second adjusting screw 7 and the radial threaded hole 12, thereby adapting to eccentric shafts of different lengths. At the same time, the position fit between the second adjusting screw 7 and the pressure plate 3 ensures that the eccentric shaft and the flywheel form the required angle α for installation.

[0024] Furthermore, the pressure plate 4 is processed with a plurality of screw holes 13, and when in use, the pressure plate 4 is fixedly mounted on the end of the eccentric shaft 1 by a plurality of screws.
