Generalised non-dimensional multi-parametric involute spur gear design model considering manufacturability and geometrical compatibility

The plane footprints inspection in computer

A general formula about the minimum number of teeth of Standard Involute Gear was given, which could avoid undercut in the tooth generating procedure This method was useful in the analysis of the undercut and interference of Involute Gear As a criterion of how to choose the number of the teeth, the formula could be used in gear transmission

Analysis on the Minimum Number of Teeth of Standard Involute Gear

Gears are crucial mechanical components and considerably used in consumer and industrial machinery. Gears can be grouped into five types namely spur, helical, rack and pinion, worm and bevel. Spur ...

An extensive analysis of frequency and transient responses in S and C-shaped gears

This article introduced neural network, discusses the neural networks model and its learning process. Using the MATLAB environment research and analysis the involute gear undercutting relationship, which under different pressure angles. In the number of teeth or modulus has been scheduled environment apply the nonlinear mapping characteristics of neural networks to involute gear undercutting do a more accurate simulation. This provides a theoretical basis for different pressure angle involute gear in gear transmission design.

Simulation and Analysis about Different Pressure Angle in Involute Gears Based on Neural Network

The principle of gear engagement and the relevant knowledge of gear geometry were used to introduce the dual meshing points involute-circular arc tooth gear in detail. At the same time, use the derived equation of the contact line and the tooth profile equation to describe the gear meshing process. Derive to this gear formula of coincidence degree calculate, in order to improve the transmission theory of the gear. Combine the gear contact line equation, equation of the tooth profile and transmission analysis, studies the meshing performance and serve as a theoretical basis for the gear design and application.

The cluster-footprint left at a crime scene is one of the most common trace evidence in the field of criminal investigation. Through analyzing and calculating the plane footprint, the investigators can get some important feature information such as step size, age and height, etc. However, this way is difficult to apply to reality without any errors in the process of manual calculations. Information management is more complicated in the later, the efficiency is relatively low too. To solve above problems, a testing system is designed and developed to analyze cluster-footprint. This system is based on the LabVIEW platform, which can realize image acquisition, stride characteristics extraction, information management and so on. Actual analysis results show that this system can effectively achieve these functions, working accuracy and efficiency can meet requirements of criminal investigation process.

This paper analysis a steel chimney outer wall with a spiral guide plate. Through calculation the steel chimney structure modal, self-vibration and wind vibration frequency verify this steel chimney can reduce the wind load impact on the chimney and flange connection. Achieve a method of improved the strength of chimney structure. The chimney under wind load resonant frequency band is reduced effectively and obtained a more stable exterior structure, offered basis for steel chimney transform in wind vibration problem.

This paper is based on the neural network nonlinear mapping characteristics. The involute gear tooth number, modulus and their relationship model of cutting the amount effect are established respectively. Through MATLAB simulation gets the relation curve between the number of teeth and modulus. These curves can intuitive reflect the tooth number and modulus effects on cutting amount change, which provides valuable theoretical reference for the design of the involute gear.
