Intisari— PT. Diametral Involute merupakan salah satu perusahaan industri logam yang bergerak dalam bidang komponen/spare part mesin.Sebelum melaksanakan proses produksi perlu adanya pemeriksaan persediaan bahan baku. Namun, baku masih acuan agar dapat memperoleh optimal.Berdasarkan hal tersebut, maka diperlukan suatu sistem perencanaan kebutuhan baik dengan menggunakan Material Requirement Pla...

To solve the design problem of non-circular gears with cusp pitch curves, this paper proposed a new variable-involute and incomplete variable-cycloid composite tooth profile (VIIVC-CTF), deduced VIIVC-CTF mathematical model, constructed conjugate gear model based on envelope method. The software curve was developed MATLAB. variation law rolling radius an cycloid its characteristics such as pres...

The computer program GearKURT has been created to calculate mechanical gears. allows you gears:
 - closed cylindrical spur gear
 helical open Novikov's bevel gear with indirect teeth
 worm-gear.
 a dialog interface written in the object-oriented programming language Delphi and compiled into an exe-file. choose necessary material method of heat treatment for manufacture gears...

Original scientific paper As the basic part of the mechanical transmission, gears should have high transmission accuracy, so the gear’s precision measurement is a key technology. Based on the existing research, the computer vision technology is introduced in gear test. According to the definitions of technical indexes, such as pitch deviation, tooth thickness deviation, etc., through analysis a...

Curvilinear tooth gears are commonly produced on a face milling cutter and a hob cutter. However, this paper proposes a kind of curvilinear tooth gear which is processed by a parallel linkage with a single blade cutter. For the purpose of identifying the meshing and contact characteristics of curvilinear tooth gears, the paper covers the following: (i) equations of tooth surfaces are deduced fr...

The precision rotary vector reducer with involute variable tooth thickness (PRVT) is a high-performance transmission device, which very suitable for aerospace, medical machinery, industrial robots, automation equipment, and other fields, its torsional stiffness an important performance index. This paper establishes dynamics model of the whole machine based on Lagrangian method by considering ge...

This is a geometric approach to spatial involute gearing which has recently been developed by Jack Phillips [4]. Due to Phillips' fundamental theorems helical involute gears for parallel axes (Fig. 2) serve also as tooth flanks for a uniform transmission between skew axes, and the transmission ratio is even independent of the relative position of the axes.
