Description

II

Изобретение относитс  к области машиностроени .The invention relates to the field of engineering.

Известно шпоночное соединение вала со ступицей с помощью призматической шпонки с выступом, нависающим над поверхностью вала.Known keyed connection of the shaft with the hub using a prismatic key with a protrusion hanging over the surface of the shaft.

Однако в известном шпоночном соедииении ступица имеет возмо кность осевого смещени .However, in the known keyway, the hub has an axial displacement capability.

Цель изобретени  - обеспечение фиксации ступицы от осевого смещени . Это достигаетс  тем, что выступ щпоики выполнен с поперечной канавкой, образующей отгибаемую на торец ступицы головку.The purpose of the invention is to secure the hub against axial displacement. This is achieved by the fact that the protrusion of the blade is made with a transverse groove forming a head that is bent on the end of the hub.

Шпонка может быть выполнена с двум  выступами .The key can be made with two protrusions.

На фиг. 1 представлено описываемое щпоночное соединение; на фиг. 2 изображена шпонка, вид сверху; на фиг. 3 показано шпоночное соединение, вариант (шпонка с двусторонней фиксацией).FIG. 1 shows the described keyed connection; in fig. 2 shows a key, top view; in fig. 3 shows keyed connection, option (key with double-sided locking).

Призматическа  щпонка 1 установлена в шпоночном пазу вала 2, на который посажена ступица 3. Шпонка выполнена с выступом 4, нависающим над поверхностью вала, а наThe prismatic key 1 is installed in the keyway of the shaft 2, on which the hub 3 is seated. The key is made with a protrusion 4 hanging over the surface of the shaft, and

верхней поверхности выступа имеетс  поперечна  канавка а. Канавка несколько ослабл ет поперечное сечение выступа, что позвол ет образовать отгибаемую иа торец ступицы головку 5.the upper surface of the protrusion has a transverse groove a. The groove slightly weakens the cross-section of the protrusion, which makes it possible to form the bendable end of the hub head 5.

Шпонка может быть выполнена с одним или двум  выступами, каждый из которых отгибают на торец ступицы в том случае, если на валу нет ступеней, удерживающих ступицы от осевого смещени  в одном из направлений.The key can be made with one or two protrusions, each of which is bent to the end of the hub in the event that there are no steps on the shaft that hold the hubs from axial displacement in one direction.
