The article provides some theoretical basis for technical design and critical evaluation of jaw crushers. The general advantages of jaw crushers are high productivity, simplicity of design, low cost and ease of repair; Disadvantages - frequency of work and the presence of large swinging masses, which produces a lot of noise during operation and causes vibrations in the factory building. Therefore, the issue of balancing a jaw crusher is very important for practice. Typically, one jaw is installed stationary, while the other receives swings from the drive mechanism. The author examines the design types of jaw crushers, the location and shape of the jaws, determines the most advantageous shaft speed, productivity and energy consumption and other indicators (see article).
Precise control of the speed of engine machines is one of the most important tasks of modern mechanical engineering. This book aims to fill these gaps and presents the experience of a systematic presentation of the practically applied theory of drum governors, mainly based on our own research and six years of experience in the design and construction of drum governors . The work covers in detail the following topics: centrifugal and drum governors, kinematics, statics, dynamics of drum governors, their design and other issues.
