[...]... Foundations for the production of timingbelts Following the introduction of cast and vulcanized endless belts, BRECO Antriebstechnik, Porta Westfalica (a member of the MULCO group) developed the thermoplastic polyurethane manufacturing processes for timingbelts in 1968 The result was open length extruded belts in rolls, later injection moulded timing belts, and extruded endless belts BRECO Company was also... diagram Why Timing Belts? If drive systems have high levels of acceleration and braking, or if they are required to precisely position at high speed, then timingbelts must be of primary interest to the designer This chapter describes the core properties of a timing belt Timingbelts work simultaneously at both high and low speeds and are particularly suited in acceleration and braking applications. .. possible then this handbook of timing belt technology would not be necessary See Fig 1.1 Therefore, this book both introduces the topic and shows which timing belt drive solutions are preferable Additionally many examples are presented as Fig 1.1 A complete timing belt drive The basic drive comprises of one timing belt and two matching pulleys R Perneder and I Osborne, HandbookTiming Belts, DOI: 10.1007/978-3-642-17755-2_1,... 202 204 205 210 5 TimingBelts in Product Transportation 5.1 State of Art 5.2 Transport Belt Design 5.3 Friction and Tribological Behaviour 5.4 Conveying, Contact Surfaces and Backings 5.5 Slide Beds/Roller Beds 5.6 Profiled TimingBelts 5.7 Example Applications of Profiled TimingBelts 5.8 Adjustable... production method is still used today for casting endless belts in closed moulds T-profile drives are now standardized in DIN 7721 Part 1 for the belts and Part 2 for the pulleys [20] In the 1960s the first use of timingbelts for automotive overhead camshaft drives was successfully pioneered by Hans Glas Automotive, using MULCO belts Through applications in the automotive industry and especially due... the marketplace These were standardized from 1977 in DIN ISO 5294 [22] for belts and in DIN ISO 5296 [20] for pulleys Fig 2.3 First worldwide application of timingbelts in Singer Sewing Machines In Germany the development and launch of the T-profile metric pitch timingbelts by the MULCO Group, Hanover began in about 1950 The belts were made of ContilanÒ, a cast polyurethane with a hardness of 90 Shore... mostly at the same bending points These are ideal application areas where the use of timingbelts will noticeably increase, as they can be perfectly integrated into production processes with many different operating conditions The timing belt combines all the advantages of conventional belts (flat, wedge and Vee-ribbed belts) such as high permissible speeds and low-noise operation and as with chain drives,... large variety of available belt profiles is inextricably linked with the evolution of the timing belt The first successful prototype applications led to the realization of the obvious practical benefits and led to rapid market introduction 2.3 Belt Profiles 13 The first timingbelts capable of being used as drive belts with matching pulleys were developed by US Rubber Corporation in the 1940’s (latterly... design of timing belt drives are readily available and thus some elements of design are available at a mouse click However, the choice of the drive components and the co-ordination with the surrounding structure will always remain the responsibility of the designer Timing Belt or Synchronous Belt? Which term is correct: Timing belt or the DIN recommended synchronous belt? Whilst Vee belts, round belts. .. correct: Timing belt or the DIN recommended synchronous belt? Whilst Vee belts, round belts and flat belts are defined by their geometric shape, synchronous belts are defined by their function The DIN ISO 5296 standard for synchronous belts includes in its explanatory text the terms ‘ timing belt’’ and ‘ timing belt pulley’’ Therefore, they can also be found in widespread use in this book 1 This book does . class="bi x0 y0 w0 h0" alt="" Handbook Timing Belts
