刨内齿工具,是东海船厂造机车间工人在缺乏加工内齿机床和生产任务紧迫情况下,完成的一项革新。该工具曾使用在B665牛头刨床上加工了72只绞缆车减速内齿轮(模数6,内径400～600毫米),加工效率和质量都比较好。刨内齿工具主要由支座、定时连续运转机构和定时制动装置三部分所组成。支座用以支承和设置定时运转机构和定时制动装置;定时 Planing internal gear tools, is the East China Sea shipyards machine shop workers in the lack of processing of internal gear machine tools and production tasks under the urgent circumstances, the completion of an innovation. The tool has been used in the B665 shaper processing 72 twisted cable car decelerating internal gear (modulus 6, diameter 400 ~ 600 mm), processing efficiency and quality are better. Planing internal tooth tools mainly by the support, timing and continuous operation of institutions and timing brake consisting of three parts. Supports for supporting and setting the timing mechanism and timing brake; Timing
