Teeth With A Study On The Performance Of Logarithmic Spiral Bevel Gear

Gear in industry applications, including aerospace, automotive, marine, metallurgy, construction machinery, etc., with the machinery and equipment to overload, large, high speed development requirements, machinery and equipment is also proceeding with continually improving, to adapt to the changing requirements of development. Gear transmission as the main mechanical equipment of gearing is constantly improving, where transmission smoothness, high load capacity, big coincidence, long life and high reliability is a gear-driven, so now there is an urgent need to improve the performance and efficiency to meet industry needs. Gear contact pattern, shape and location and size will directly reflect the performance of contact gears, therefore, to improve the performance of the first contact with the gear to get the appropriate contact area, shape and location and size.This topic is to study a new type of gear - on the number of spiral bevel gears, tooth contact area of the shape, position and size. Logarithmic spiral bevel gear on the logarithmic spiral as the gear to the line, a new type of logarithmic spiral bevel gear form, and a systematic study of spiral bevel gear tooth contact performance, introduction of spiral bevel gear tooth contact analysis of the principle of access to the ideal number of spiral bevel gear on the contact zone location, shape and size of the result. And carried out on the spiral bevel gear tooth surface of sample contact area detection experiments, obtained by the experiment on the number of spiral bevel gear contact area of the location, shape and size of the result.This study is of spiral bevel gear contact area of the solution method, in the spiral bevel gear model based on any one of them had teeth mesh, to obtain the coordinates, then a combination of elliptic function method, found logarithmic spiral bevel gear method for solving the contact area and contact area on the border of the judge and cutting, were on the ideal number of spiral bevel gear tooth contact area location, size and shape.This topic describes the logarithmic spiral bevel gear tooth contact detection methods, based on the principle of EPG detection method, the Y9550-bevel gear scroll check machine on logarithmic spiral bevel gear tooth surface contact area for the prototype lab, by experimental won the logarithmic spiral bevel gear contact areas, forms and sizes, etc. And the results of the experiment and Gleason bevel gear contact area and ideal logarithmic spiral bevel gear of contrasts the contact area, came to a logarithmic spiral bevel gear tooth contact relevant characteristics.
