Calculation method of spring and tension rod of jaw crusher
First, find out the inertial force and moment of inertia of each point on the track C of the hinge point of the tie rod and the movable jaw, analyze and calculate the stroke of the movable jaw, then obtain the larger compression of the spring force according to the kinematics and dynamics analysis methods of the jaw crusher.
In the case shown in the figure, Fbbo=0 in the figure because the toggle plate can only bear the pressure Fbb0 but not the tension. Fci can be obtained according to the moment equation of Ai point. Once the tension rod spring is in a compressed state, that is, at each position where the movable jaw is separated from the toggle plate by the inertial dynamic load, take the larger Fci value as the basis for calculating the spring. But the actual larger working compression force of the spring should be 1.5~2 times larger than Fci. And in order not to make the selected spring stiffness too large, the number of working turns of the spring should be greater than 5 turns.
Moreover, it is often necessary to adjust the preload of the spring during work. The specific method is: the pre-tightening force should be increased in this way when the new toggle plate is installed. That is, Due to the insufficient pre-tightening force, a noise is generated between the toggle plate and the toggle pad during the crusher starts idling. As the pre-tightening force is gradually increased, the noise will gradually reduce until there is no sound. Then you can fix the compression nut.
