Jaw crusher wear phenomena in daily operations is inevitable, we only do regular maintenance can extend the useful life to the maximum, so we Jaw crusher spindle, eccentric shaft and bearing long-term aspects of maintenance!
First, the axis of the wear and tear if rarely, just to fix its geometry, turning in a lathe, so that journal to the correct geometry, then the corresponding reduced bearing diameter. But after several such treatment, if the journal size reduction of 5% over the original, it does not allow re-turning, while the shaft should be replaced with new.
Again, the jaw crusher is working under the impact load, bearing on the babbitt lining, length of about two years or so, the deadline, you will need to re-cast. If the eccentric shaft and bearing, spindle and bearing are worn, the tip clearance gap of greater than 1.5 times the original assembly, the need to add pads to adjust or replace; oil groove wear 1.5 mm, should be re-opened the oil groove and adjustment. Connecting rod head cover and the gap between the eccentric shaft, wear and tear to 1.5 times greater than the assembly gap, the need to add pads to adjust or replace. When the bearing babbitt on a deeper peel or large scratches, should be re-cast. For the bearing quality after processing the following requirements: babbitt surface color to be uniform, light, silver white; babbitt surface layer should not have ash, cracks, blisters, shrinkage, etc., and peel phenomenon.
Although these two points are very small on the one hand, but in the axis of jaw crusher's maintenance is necessary, we will periodically send the Commissioner to the customer site after-sales follow-up survey to provide our customers to actively cooperate with us investigation, we need your support to grow, we in this long-term support of our customers to express my heartfelt thanks!
