Original Research on Logarithmic Spiral Bevel Gear

Abstract

In this article, logarithmic spiral curve is successfully applied to bevel gear transmission and used as dentiform line of helicoid bevel gear. Put forward a novel logarithmic spiral bevel gear drive. Because spiral angle on each point of logarithmic spiral curve is constant, the problem of variational spiral angle is solved faultlessly. Analyze the basic characteristics of logarithmic spiral curve and demonstrates the condition of the logarithmic spiral curve used as pitch curve. Put forward the new kind of transmission form of logarithmic spiral bevel gear and it makes up the deficiency in current bevel gear transmission area.

Review on logarithmic spiral bevel gear

“…Yan [25] used the finite element software ABAQUS to analyze the LSBG pair in static contact and obtained the size, shape and position of the contact area of the gear tooth surface at low speed. On this basis, further dynamic contact analysis was carried out.…”

“…Through modal analysis, the vibration characteristics of the gear structure are studied, the natural frequency of resonant damage is calculated, and reasonable vibration reduction measures are taken to reduce the vibration and noise in the process of gear transmission. Through the finite element analysis, the shape of the contact area of the LSBG tooth surface was analyzed, including the size, shape and position of the contact area in the cases of low-speed light load and high speed, furthermore heavy load [25]. Therefore, the quality of the tooth surface contact is known in advance.…”
