Sonsuz vida mekanizmaları çok küçük hacimlerde çok yüksek çevrim oranlarında güç iletebilen mekanizmalardır. Ancak diğer dişli çark mekanizmaları ile kıyaslandıklarında çok düşük verimlere sahiptirler. Ayrıca hareket dişler üzerinden kayarak iletildiği için aşınma ve ısınma problemleri vardır. Öbür taraftan aşınma sebebiyle karşılık dişlisinin imalatında kullanılan bronz pahalı bir malzemedir. Sonsuz vida mekanizmalarının dezavantajlarını ortadan kaldırmak için sonsuz vida ile karşılık dişlisi arasındaki teması bilye tanelerinin sağladığı çeşitli tasarımlar geliştirilmiştir. Bu çalışmada aynı boy ve çevrim oranlarına sahip ve aynı yağlama koşullarında sonsuz vida redüktör ile yeni tasarlanan bilyeli sonsuz vida redüktörün verimleri, dişli verimliliği belirleme deney düzeneğinde deneysel olarak karşılaştırılmıştır. Deneyler sonucunda sabit devirde frenleme momentinin artmasıyla her iki mekanizmanın da verimlerinin arttığı gözlemlenmiştir. Sabit devir ve frenleme momenti altında bilyeli sonsuz vida mekanizması geleneksel sonsuz vida mekanizmasına göre daha yüksek verim sergilemiştir.
Eternal vibration mechanisms are mechanisms that can transmit power at very high circuit rates in very small volumes. However, when compared to other tooth wheel mechanisms, they have very low efficiency. There are also swelling and heating problems because the movement is transmitted by swelling through the teeth. On the other hand, bronze is a expensive material used in the manufacture of the toothbrush due to the coating. To eradicate the disadvantages of the infinite vibration mechanisms, the contact between the infinite vibration and the corresponding dentist has been developed with a variety of designs provided by the ball tanks. In this study, the performance of the newly designed balled infinite vibration reducer with the same size and circle ratio and in the same lubrication conditions with the infinite vibration reducer, the dental efficiency determination is experimentally compared in the experimental arrangement. Experiments have shown that with the increase in the braking moment in the fixed circuit, both mechanisms have increased their efficiency. Under the fixed rotation and braking moment, the balled infinite wire mechanism has shown higher efficiency than the traditional infinite wire mechanism.
Worm gear mechanism transmits power in very small volumes at very high gear ratios. However, their efficiency is very low compared with other gear mechanisms. They have also wear and overheating problems because of force transmission with sliding. On the other hand, bronze is an inexpensive material used in the manufacture of the worm wheel due to wear. Various designs, that provides the contact between the worm gear and the worm wheel by balls have been developed to eliminate the disadvantages of worm gear mechanisms. In this study, the efficiency of the conventional worm gear mechanism and newly designed ball worm gear mechanism which have the same gear ratio and same center distance have been compared experimentally under the same lubrication conditions. Results showed that the efficiency of both mechanisms increases with increasing brake torque at a constant speed. In addition, under constant speed and brake torque, the ball worm gear mechanism showed higher efficiency than the worm gear mechanism.
