Abstract

ABSTRACT

In this study, the effects of type of wooden material and cutting section of wood on the holding strength of screw nut have been researched. For this purpose, the specimens prepared from scots pine (Pinus sylvestris L.) wood, beech (Fagus orientalis Lipsky.) wood and oak (Quercus petraea Lieble.) were applied. The tests of static tensile strength according to the standards of ASTM-D 1767-68. As the results, the tensile strength of screw is the highest in oak and the lowest in scots pine wood according to the wood type. The highest value has been obtained as radial to growth rings and the lowest as along the grain. Technical and economical benefits can be provided with taking these test results into consideration.

FARKLI AĞAÇ MALZEMELERDE KESİŞ YÖNÜNÜN SOKET VİDA TUTMA MUKAVEMETİNE ETKİLERİ

Abstract

Bu çalışmada, ağaç malzeme türü ve ağaç malzeme kesiş yönünün soket vida tutma mukavemetine etkileri araştırılmıştır. Bu amaçla sarıçam (Pinus sylvestris L.), Doğu kayını (Fagus orientalis Lipsky.) ve meşe (Quercus petraea Lieble.) odunlarından hazırlanan örneklere ASTM-D 1767-68 esaslarına uyularak statik çekme direnci deneyleri uygulanmıştır. Sonuç olarak, ağaç türü için soket vida tutma direnci en yüksek meşede en düşük sarıçamda, kesiş yönü için en yüksek yıllık halkalara radyal, en düşük liflere paralel yönde elde edilmiştir. Bu deney sonuçlarının dikkate alınması ile mobilya konstrüksiyon tasarımında ilgililere teknik ve ekonomik yararlar sağlanabilir
