Abstract

Изобретение относитс к машиностроению и может быть использовано дл надежного закреплени осей, пальцев, штоков и тому подобных цилиндрических деталей в осевом направлении и стопорени их от вращени . Цель изобретени - улучшение условий эксплуатации. Устройство содержит ось 1 и охватывающие детали, одна из которых - привертна крышка 2. Установленный в канавке оси и полости крышки пружинный стопор состоит из рабочих и упругих участков. Упругие участки расположены в канавке крышки, а рабочие наход тс в зацеплении с выборками на оси. Стопор фиксируетс от углового смещени путем ввода отогнутых лапок 7 в отверсти крышки. Контактирующие поверхности выборок оси и рабочих участков стопора эквидистантны. Ось ориентирована относительно стопора посредством совмещени соответствующих меток, нанесенных на одном из ее торцов и на смежной охватывающей детали. На одном конце оси имеетс рифление 9, или гнездо (головка) под ключ (руко тку). 6 ил.The invention relates to mechanical engineering and can be used to secure axles, fingers, rods and the like of cylindrical parts in the axial direction and prevent them from rotating. The purpose of the invention is to improve the operating conditions. The device contains an axis 1 and the female parts, one of which is a screw-top cover 2. A spring stopper installed in the axis groove and cavity of the lid consists of working and elastic sections. The resilient portions are located in the groove of the lid, and the workers are engaged with the samples on the axis. The stopper is secured against angular displacement by inserting bent legs 7 into the openings of the cover. The contact surfaces of the samples of the axis and the working sections of the stopper are equidistant. The axis is oriented relative to the stopper by aligning the respective marks applied on one of its ends and on the adjacent female part. At one end of the axis there is a groove 9, or a socket (head) with a key (a handle). 6 Il.
