DOWNLOAD EBOOKUnderstanding how gears are formed and how they interact or ‘mesh’ with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the topic of this book. Gears and Gear Drives provides the reader with comprehensive coverage of gears and gear drives. Spur, helical, bevel, worm and planetary gears are all covered, with consideration given to their classification, geometry, kinematics, accuracy control, load capacity and manufacturing. Cylindrical gear geometry is the basis for dealing with any gear drives, so this is covered in detail. Key features: Contains hundreds of 2D and 3D figures to illustrate all types of gears and gear drives, including planetary and worm gears Includes fundamental derivations and explanations of formulae Enables the reader to know how to carry out accuracy control and load capacity checks for any gear drive Includes directions for the practical design of gears and gear drives Covers DIN and ISO standards in the area Gears and Gear Drives is a comprehensive reference for gears and gear drive professionals and graduate students in mechanical engineering departments and covers everything important to know how to design, control and manufacture gear drives.

DOWNLOAD EBOOKAnnotation Rakhit wants other engineers to avoid the considerable trouble he had understanding the art of gear heat treatment when he first embarked on a career in gear design and manufacturing. He explains how heat treating and gears made of some kinds of steel gives the gears high geometric accuracy, but can also distort them and raise the cost of manufacturing, so a gear engineer needs to excel in manufacturing, lubrication, life and failure analysis, and machine design as well as design. He presents a case history of each successful gear heat treatment process that provide information on the quality of gear that can be expected with the proper control of material and processes.

DOWNLOAD EBOOKThe book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

DOWNLOAD EBOOKWinner of the 2019 Newbery Medal Thoughtful, strong-willed sixth-grader Merci Suarez navigates difficult changes with friends, family, and everyone in between in a resonant new novel from Meg Medina. Merci Suarez knew that sixth grade would be different, but she had no idea just how different. For starters, Merci has never been like the other kids at her private school in Florida, because she and her older brother, Roli, are scholarship students. They don’t have a big house or a fancy boat, and they have to do extra community service to make up for their free tuition. So when bossy Edna Santos sets her sights on the new boy who happens to be Merci’s school-assigned Sunshine Buddy, Merci becomes the target of Edna’s jealousy. Things aren't going well at home, either: Merci’s grandfather and most trusted ally, Lolo, has been acting strangely lately — forgetting important things, falling from his bike, and getting angry over nothing. No one in her family will tell Merci what's going on, so she’s left to her own worries, while also feeling all on her own at school. In a coming-of-age tale full of humor and wisdom, award-winning author Meg Medina gets to the heart of the confusion and constant change that defines middle school — and the steadfast connection that defines family.

DOWNLOAD EBOOKOf all the many types of machine elements which exist today, gears are among the most commonly used. The basic idea of a wheel with teeth is extremely simple, and dates back several thousand years. It is obvious to any observer that one gear drives another by means of the meshing teeth, and to the person who has never studied gears, it might seem that no further explanation is required. It may therefore come as a surprise to discover the large quantity of geometric theory that exists on the subject of gears, and to find that there is probably no branch of mechanical engineering where theory and practice are more closely linked. Enormous improvements have been made in the performance of gears during the last two hundred years or so, and this has been due principally to the careful attention given to the shape of the teeth. The theoretical shape of the tooth profile used in most modern gears is an involute. When precision gears are cut by modern gear-cutting machines, the accuracy with which the actual teeth conform to their theoretical shape is quite remarkable, and far exceeds the accuracy which is attained in the manufacture of most other types of machine elements. The first part of this book deals with spur gears, which are gears with teeth that are parallel to the gear axis. The second part describes helical gears, whose teeth form helices about the gear axis.

DOWNLOAD EBOOKAward-winning archaeologists and New York Times and USA Today bestselling authors W. Michael Gear and Kathleen O'Neal Gear begin the stunning saga of the North American equivalent of ancient Rome in People of the Morning Star. The city of Cahokia, at its height, covered more than six square miles around what is now St. Louis and included structures more than ten stories high. Cahokian warriors and traders roamed from the Great Lakes to the Gulf of Mexico. What force on earth would motivate hundreds of thousands of people to pick up, move hundreds of miles, and once plopped down amidst a polyglot of strangers, build an incredible city? A religious miracle: the Cahokians believed that the divine hero Morning Star had been resurrected in the flesh. But not all is fine and stable in glorious Cahokia. To the astonishment of the ruling clan, an attempt is made on the living god's life. Now it is up to Morning Star's aunt, Matron Blue Heron, to keep it quiet until she can uncover the plot and bring the culprits to justice. If she fails, Cahokia will be torn asunder in warfare, rage, and blood as civil war consumes them all.
