Description

Изобретение относитс  к области общего машиностроени . По основно-му авт. св. № 348782 известна призматическа  шпонк на одном из торцов которой выполнен скос дл  обеспечени  демонтажа шпонки. Ввиду то по., что при демонтаже неизвест но, какой торси выполнен со скосом, то вы бор торца, к которому прилагаетс  усилие, производитс  наугад, что удлин ет врем  демонтажа оборудовани . Целью изобретени   вл етс  упрощение демонтажа. Это достигаетс  тем, что предлагаема  шпонка имеет дополнительный скос, в-ьшолненный на другом торце. На фиг. 1 показана предлагаема  шпонка; на фиг. 2 - возможные положени  щпон ки в момент ее демонтажа; на фиг. 3 - поперечный разрез соединени  ступицы с валом шпонкой. Шпонка 1 соедин ет ступицу 2 с валом 3. Высота скоса больше или равна глубине шлончатого паза, а ширина равна или меньше радиуса скрутлени . В этом случае дл  д&монтажа шпонки усилие прикладьюаетс  к любому из скругленных торцов. Предмет изобретен11  Призматическа  шпонка по авт. св. 348782, отличаюша с  тем, что, с целью упрощени  демонтажа, она имеет дополнительный скос, выполненный на другом ее торце.This invention relates to the field of general engineering. By main auth. St. No. 348782 is a known prismatic key at one of the ends of which a bevel is made to ensure dismounting of the key. In view of the fact that during dismantling it is not known which torso is made with a bevel, the selection of the end to which the force is applied is made at random, which lengthens the time for dismantling the equipment. The aim of the invention is to simplify dismantling. This is achieved by the fact that the proposed key has an additional bevel, which is sintered at the other end. FIG. 1 shows the proposed key; in fig. 2 - possible positions of the clamp at the moment of its dismantling; in fig. 3 shows a cross-section of the connection between the hub and the shaft with a key. A key 1 connects the hub 2 to the shaft 3. The height of the bevel is greater than or equal to the depth of the slit groove, and the width is equal to or less than the twist radius. In this case, a force is applied to any of the rounded ends for d & key mounting. Item invented11 Prismatic key by author. St. 348782, distinguished by the fact that, in order to simplify dismantling, it has an additional bevel, made on its other end.
