“…Dimensional wear of the rear surfaces (RS), which causes uneven thinning of the tool teeth, leads to an unacceptable decrease in accuracy in the process of combined gear cutting. Therefore, for the eighth degree of accuracy (GOST 1643-81) of crowns processed by cylindrical gear, the permissible deviation of the involute profile of the side surfaces of the tool teeth should not exceed 0.04 mm per side [5,6]. In some value judgments were given about the period of durability of the tool in question.…”

The article deals with the aspects of improving the performance of a combined cutting and deforming tool designed for finishing gear machining of cylindrical gears. Presented are currently relevant proposals on the prospects for the applicability of wear-resistant coatings for this type of tool. It is emphasized that regardless of where coatings are used, they all have one thing in common: the coating changes the surface properties of the tool.

ПРИСПОСОБЛЕНИЯ ДЛЯ ЗАКРЕПЛЕНИЯ ОБРАЗЦОВ ВО ВРЕМЯ ПРОВЕДЕНИЯ ЭКСПЕРИМЕНТАЛЬНЫХ ИССЛЕДОВАНИЙРассмотрены вопросы, связанные с конст-руктивными особенностями различных разрабо-танных и изготовленных приспособлений для кре-пления экспериментальных образцов на зубофре-зерных станках во время силовых и стойкостных исследований. Рассмотрены способы установки и крепления как экспериментальных образцов, так и приспособлений.Ключевые слова: эксперимент, сборная червячная фреза, зубчатая рейка, приспособление, конструкция, образец. N.D. Feofilov, E.S. Yanov, A.S. Yamnikov DEVICES FOR SAMPLE FASTENING DURING EXPERIMENTAL INVESTIGATIONSThe paper reports the consideration of problems connected with design peculiarities of devices for sample fastening on gear-milling machines during the investigation fulfillment of a gear milling process of cylindrical wheels with combined hob milling cutters. The essence of the problem is reduced to that the fulfillment of investigations directed to the definition of a hob durability term and also of the modes and a force of cutting upon real large cog-wheels is not always possible as on domestic engineering enterprises they are manufactured mostly with small-lot or limited production and their price is high. Therefore, it is offered to substitute expensive and long experiments for experiments with special samples. In the paper there are described designs and circuits of the installation of the devices developed for such samples. In conclusion there are shown test results and is made a conclusion of that the use of the devices offered allowed defining and correcting tool parameters, cutting modes, defining a tool durability period at the stage of technological preproduction of manufacturing large cog-wheels made of hardened steel.
