Description
II
Изобретение относитс к горной промышленности, а именно к режущим инструг ентам исполнительны с органов горных машин.The invention relates to the mining industry, namely, to cutting tools, executives from the organs of mining machines.
Известны резцы дл горных машин, включающие корпус, установленный в кулаке с возможностью свободного поворота , рабочую головку, хвостовик и фиксирующий элемент Г11Known cutters for mining machines, including the body mounted in a fist with the possibility of free rotation, the working head, the shank and the locking element G11
Недостаток таких резцов - малый крут щий момент относительно оси резца.The lack of such incisors is a small torque relative to the axis of the incisor.
Наиболее близким техническим решением вл етс резец дл горных машин, включающий корпус, установленный в кулаке с возможностью свободного поворота , рабочую головку, и хвостовик с замкнутой проточкой под фиксатор t23.The closest technical solution is a cutter for mining machines, which includes a housing mounted in a cam with the possibility of free rotation, a working head, and a shank with a closed groove under the lock t23.
Недостаток таких резцов - их мала износостойкость вследствие неравномерного поворота в процессе ра- . -боты.The disadvantage of such incisors is their low wear resistance due to the uneven rotation in the process. -bots
Цель изобретени - повышение износостойкости резца за счет.увеличени интенсивности его поворота.The purpose of the invention is to increase the wear resistance of the cutter due to the increase in the intensity of its rotation.
Поставленна цель достигаетс тем, что в резце дл горных машин, включающем корпус, установленный в кулаке с возможностью свободного поворота , рабочую, головку и хвостовик с замкнутой проточкой под фиксатор, проточка хвостовика образована двум синусоидальными кривыми.This goal is achieved by the fact that in the cutter for mining machines, which includes a housing mounted in a fist with the possibility of free rotation, a working head, a shaft and a shank with a closed groove under the retainer, the groove of the shank is formed by two sinusoidal curves.
На фиг. 1 показан резец, общий вид; на фиг. 2 - развертка замкнутой проточки.FIG. 1 shows a cutter, a general view; in fig. 2 - scan of the closed groove.
