Working A ‘Toggle and Pitman’ is the popular mechanism driving the Blake jaw crusher It normally comprises of a pitman working on an eccentric on the crusher shaft and two toggles travelling and traversing like a ‘birds wings’ one between the main frame and the pitman and the other between the pitman and the moveable jaw so that

pitman in jaw crusher Jaw Crushers McLanahan produces single toggle jaw crushers which feature a pitman mounted on an eccentric shaft at the top At the bottom of the assembly the pitman is held in position by a toggle plate The combination of eccentric motion at the top and rocking motion at the bottom provides a positive downward thrust throughout the crushing chamber

The 48 by 42 inch jaw crusher and smaller sizes are force fed by an automatic high pressure lubricator to the swing jaw pitman and main bearings as illustrated in Figure 1 A motor driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings

Jaw Crusher Flywheel Rotational energy is fed into the jaw crusher eccentric shaft by means of a sheave pulley which usually has multiple Vbelt grooves In addition to turning the pitman eccentric shaft it usually has a substantial mass to help maintain rotational inertia as the jaw crushes material Jaw Crusher Tension Rod
