Understanding 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.

Young readers can learn all about how gears connect and help machines move in this innovative novelty book with adorable rhyming text. With seven spinning wheels that connect to and spin one another, this unique book is an interactive introduction to engineering. Full color.

An original novel based on the groundbreaking and award-winning military sci-fi-action video game series Gears of WarNwritten by #1 "New York Times"-bestselling author Traviss. Available in a tall Premium Edition.

Be present, connect more effectively, all while being as productive as possible 5 Gears: How to Be Present and Productive When There Is Never Enough Time teaches you to shift into the right gear at the right time so that you can grow in your relational intelligence and increase your influence. This revolutionary text introduces you to the five different gears, or mindsets, that carry you through various facets of your day. These include: First gear—when you fully rest and recharge Second gear—when you connect with family or friends without the involvement of work Third gear—when you are socializing Fourth gear—when you are working and multi-tasking Fifth gear—when you are fully focused and 'in the zone,' working without interruption Using these gears consistently allows you to bring a new level of relational intelligence to your life that offers a competitive advantage in our task-driven world. All too often people go through life without truly connecting—and can, as a result, miss out on experiences and relationships that have the power to bring them great joy. By understanding how the five gears presented in this engaging book work, you can improve your ability to connect with the world around you. Explore why some people stay disconnected from the people and events around them, and why others always seem to have a deep connection to their friends, family, and surroundings Learn how to set triggers and markers that help you shift into the right gears at the right time, which will increase your relational dynamics and make you more productive Create positive change in the dynamics of your relationships Improve your respect and influence—and learn a sign language that, when used, can change your perspective and your world. 5 Gears: How to Be Present and Productive When There Is Never Enough Time is the perfect resource for anyone who wants to live and lead connected.

The 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

Still mourning the loss of Lucas Nelson, the boy she loved in secret for years, seventeen-year-old Emmy Martin turns to her passion for mountain biking to try to fill the empty void in her life. But just when things start looking up, Emmy discovers her mom has been diagnosed with early-onset Alzheimer’s. Confused and angry, she throws herself into mountain biking like never before. She wants to improve on the trails, get a sponsor, and finally beat her nemesis, Whitney. When Cole Evans, a boy from school who usually doesn’t care about anything but himself, offers to train her for the biggest race of the season, she accepts, determined to beat Whitney. The more time she spends with Cole, the more she realizes he’s different than she’d expected, and, to her surprise, she’s falling for him. Torn between the deep feelings she still has for Lucas and her growing ones for Cole, she knows she must choose a path. As she drifts further away from her family and closer to her dream of being sponsored, a terrible accident threatens any semblance of peace and happiness she has left. Instead of closing herself off to the people she loves, Emmy must learn to rely on those she has pushed away if she’s going to have any chance of picking up where she left off before the accident.
