Related to gear strength so that it is influenced by material, pitch, pressure angle, profile shifting amount, tooth width, heat treating methods, etc. Related to shock at start and stop time.Related to the weight and maintainabilityĭetermines mainly the size, form, material (specific gravity), and method of shaft attachment.Īffects the decisions chiefly on precision grade, need for tooth grinding, use of crowning or end relief, material, amount of backlash and lubrication method.Since it is mostly determined by the bending and tooth surface strengths, it influences the decision on material, pitch, pressure angle, profile shifting amount, tooth width, heat treating methods, etc. use of racks for linear motion).ĭetermined by the choices of numbers of teeth. The amount of force transmission and the required strength of gearsĬhiefly conditions affecting bending and tooth surface strengths which are determined by material, pitch, pressure angle, profile shifting amount, tooth width, heat treating methods, etc.Īffects the decision of tooth helix direction and type of gears (e.g.– Amount and direction of force considerations – mainly related to the required performance of gears Therefore, these tooth widths and outside diameters can be restricted by the machine’s design itself. Normally various elements of mechanism within the interior of the machine are placed to utilize space efficiently. The decisions on tooth widths and outside diameters are affected by this. Normally gears matching the center distance between the shafts is used, but there are occasions when profile shifting is used. – Dimensional considerations – mainly related to space restrictions of the machine design The main conditions for determining these elements are listed below : Various elements of gear design and the conditions for determining elementsįor design of gears, determine elements such as size, tooth shape, pitch, number of teeth, amount of profile shift, material, need for heat treating and/or grinding, choice for kind of tooth surface finish, amount of backlash, helix angle, helix direction, method of mounting on shaft, precision class, etc., the production process and the method of lubrication. (At present, the secondary operations are limited to the features supported in the standard stock gears.) Use it by entering a KHK part number in the gray colored middle column on a stock gears page.
