Resumo: | The use of polymeric materials to substitute an array of others like metal has its development level increased when new compounds are applied as well as new formation technologies. An approach of the main factors lately used for its assessment was necessary to prove the polymeric material?s behavior when applied in gears for strength transmission. The presented analysis were based on practical experiences and through methods of finite elements, using diverse composites and addition loads to form the tested polymers in controlled conditions for torque, temperature and rotation, making use of the device development of movement and specific control. The polymeric gears behave in different ways according to specific conditions of temperature, rotation and torque request, presenting a variety of results due to the polymers used in its formation. The geometry of the project and the profile construction of the conical gears? tooth had direct influence under the performance, being possible to reduce the tensions in the tooth?s root.

Uma abordagem dos principais fatores ultimamente utilizados para sua avalia??o fez-se necess?ria para a comprova??o do comportamento dos materiais polim?ricos na aplica??o em engrenagens de transmiss?o de for?a. As an?lises apresentadas foram baseadas em experimenta??es pr?ticas e atrav?s de m?todos de elementos finitos, utilizando diversos comp?sitos e cargas de adi??o para forma??o dos pol?meros testados em condi??es controladas de torque, temperatura e rota??o, utilizando-se de desenvolvimento de dispositivo de movimenta??o e controle espec?fico. As engrenagens polim?ricas comportaram-se de diferentes formas em condi??es espec?ficas de temperatura, rota??o e solicita??o de torque, apresentando resultados variados em fun??o dos pol?meros utilizados em sua forma??o. A geometria de projeto e constru??o do perfil do dente das engrenagens c?nicas teve influ?ncia direta em rela??o ao desempenho, sendo poss?vel a redu??o das tens?es na raiz do dente. As pe?as injetadas forneceram corpos de prova para an?lises t?rmico din?mico mec?nicas, os resultados destas apresentaram discrep?ncia entre os materiais base no que se refere a Tm. A substitui??o de materais met?licos por materiais polim?ricos deve levar em considera??o as caracter?sticas para cada aplica??o.Submitted by Caroline Xavier (caroline.xavier@pucrs.br) on 2017-10-05T11:34:54Z No. of bitstreams: 1 TES_LUIS_FERNANDO_MELEGARI_COMPLETO.pdf: 6221745 bytes, checksum: 6fea166b18494e244d24dddc530d9abc (MD5)Approved for entry into archive by Caroline Xavier (caroline.xavier@pucrs.br) on 2017-10-05T11:35:04Z (GMT) No. of bitstreams: 1 TES_LUIS_FERNANDO_MELEGARI_COMPLETO.pdf: 6221745 bytes, checksum: 6fea166b18494e244d24dddc530d9abc (MD5)Made available in DSpace on 2017-10-05T11:35:13Z (GMT).
