Jaw crusher moving jaw and bearing coupling structure improv

Jaw crusher has moving jaw and stationary jaw the two jaws trench broken cavity, the rotation of the eccentric shaft of the motor driven pulley and associated fixed in the course of their work, the use of dynamic, given the relative motion between the jaw achieve ore crushing device. With a jaw crusher simple structure, easy to manufacture, reliable work,a nd other advantages, jaw crusher widely used in subsection Hill building materials, metallurgy, chemical and other infrastructure construction.

With the development of modern industry and the continuous progress of science and technology, field operations, such as open-pit mining, sand, road, large and medium-sized jaw crusher not only meet its life and reliable, stable operation requirements, but also to adapt to the maintenance of field operations convenient shortcuts demand. Due to a jaw crusher working environment is generally poor field conditions, far away from the service station or factory, can not be equipped with a complete and proper maintenance, assembly and disassembly fixture in such cases, the need to improve the structure of the jaw crusher Yifan Machinery design, to further meet the maintenance requirements in field operations under conditions suitable for demolition.

Usually jaw crusher's movable jaw and a movable jaw bearing outer ring is designed for cylindrical bore, with the the moving jaw bearing bore and the eccentric shaft with an interference fit fixed bearing assembly pressed into the assembly method or hot charging method, which kinds of design structure is very inconvenient to use in the field. This structure to retreat drogue connection forms between the moving jaw and a movable jaw bearing design a retreat outside the drogue. When handling bearings, elastic retreat put on the outer cone screw can be screwed tight and remove the outer cone sets, moving jaw bearing is also very convenient, easily fixed on the movable jaw body proper position.

Moving to the upper jaw crusher jaw and a bearing coupling structure improvements, jaw crusher has been some improvement in performance. In the development process, the company mastered the core technology of the crusher machine industry into the modern production process, create a professional crusher equipment for customers.
