The toggle plate is an important and wear-resistant parts of jaw crusher, analyzes the elements of its rolling, is conducive to improve the structure of jaw crusher, jaw crusher of the progress of work ability.

Because the elbow plate pendulum angle on the jaw head track performance value of the impact is very small, so in the organization scale optimization, elbow plate pendulum angle is given as the original data. Elbow board length and swing angle value relevant, increasing the toggle plate swing angle, can reduce the toggle plate length scale. Thus, if the optimal design of organization scale, given the large swing angle will be toggle the lighter, this regarding the easy consumption of the metal saving cost is very favorable.

The crusher toggle plate movement is simplified to analyze the unknown, when the transmission angle is smaller than the angle of friction, the toggle plate will not attack slide. Therefore, to ensure that the elbow plate in the liner between the pure rolling condition is:, which is the driving force angle, 1is the conflict angle, 4 is a toggle plate swing angle, f is the conflict between the toggle plate with gasket coefficient. Because the elbow board and liner for dry conflict, if f=0.015. Considering the discharge port adjusting, mechanical wear and liner with jaw head swing etc. factors on; incremental 4 accounting value, the limiting swinging angle values to correct, to ensure that the pure rolling, elbow board take;.

The above ideas can get small angle long toggle plate structure. From the crusher varying motion mechanism of long rod high side tissue analysis can be seen, the traditional view of the adoption of small angle long toggle plate should be corrected. Therefore, the jaw head pad in the tissue during exercise, do not always move in parallel, and the elbow board and the two pad contact point range with tissue motion changes, because the toggle plate force is not always after fixed bearing.

Because the jaw head is usually planar motion component, thus jaw head of translational and tumbling liner exist two kinds of relative motion of elbow board, jaw head gasket relative translational and ancon plate sliding independent, and know the head gasket on the jaw toggle plate relative roll.

The toggle plate pure rolling conditions to analyze the knowable, tissue motion when the toggle plate Is it right? Attack sliding, and the toggle plate swing angle not attack relationship, the maximum toggle plate depends on the jaw head relative swing angle Is it right? Satisfactory elbow plate pure rolling condition the rules.

To sum up, when the organization movement the elbow plate Is it right? Attack sliding, and the toggle plate swing angle (or elbow board length scale) has nothing to do, but only with the jaw head and elbow board due to movement of the machine and the discharge port adjusting as a result of the relative swing angle. Because of swing angle value is usually very small, rolling condition and satisfactory elbow plate pure rolling rules, thus moving crusher, the toggle plate will be pure rolling in the liner between. Thus the crusher can choose short elbow board structure, the decrease of consumables costs and reduce heavy metal machine is very favorable.
