Lesson 32 Limits and Tolerances
一、预备知识
Grippers by ZAYTRAN are universally applicable "out-of-the-box". The use of third-generation ZAYTRAN technology and the selection of super tough, corrosive resistant materials allow these products to efficiently serve day-to-day as well as tough, nearly impossible gripper applications BUT are priced competitively with commodity products! ZAYTRAN gripper technology provides precision in extreme environments such as clean rooms, grinder loading, automotive, and die casting. 预备知识

Text & Translation
Mechanical design should be considered to be an opportunity to use innovative talents to envision a design of a product, to analyze the system and then make sound judgments on how the product is to be manufactured. It is important to understand the fundamentals of engineering rather than memorize mere facts and equations. There are no facts or equations which alone can be used to provide all the correct decisions required to produce a good design. On the other hand, any calculations made must be done with the utmost cle, if a decimal point is misplaced, an otherwise acceptable design may not function.
Text & Translation
People who perform the various functions of mechanical design are typically called designers, or design engineers. Mechanical design is basically a creative activity. However, in addition to being innovative, a design engineer must also have a solid background in the areas of mechanical drawing, kinematics, dynamics, materials engineering, strength of materials and manufacturing processes.

Dynamics
The study of the motion of bodies under the action of forces It includes the study of forces, torque, and moments acting on bodies
First Law of Thermodynamics
The development of mechanical engineering has undergone an evolution from manual manufacturing to modern manufacturing. With the continuous progress of technology, mechanical engineering has also made new breakthroughs in both theory and practice.
Connection is the key to achieving mechanical assembly, and connection design needs to consider factors such as connection method, fasteners, and sealing.
Computer aided design
Computer aided design is an important tool in modern mechanical design, which can help designers complete design tasks quickly and accurately.

Helical gears subject the shaft bearings to both radial and thrust loads.
斜齿轮使轴承承受径向力和轴向力。 When the thrust loads become high or are
objectionable for other reasons, it may be desirable to use double helical gears. 当轴向力过大或由于别的原因而产生不利影响时, 那就可能需要使用人字齿轮。
A pair of meshed crossed helical gears usually have the same hand; that is, a right-hand driver
goes with a right-hand driven. 一对相互啮合的交错轴斜齿轮通常具有同样的齿 向,即右旋主动齿轮跟右旋从动齿轮相啮合。
