Description

нагруженное крут щим циклическим моментом; на фиг. 3 - то же, вид сбоку.loaded with cyclic torque; in fig. 3 - the same, side view.

Упругое неподвижное соединение (см. 4|иг. 1) выполнено дл условий нагружени циклической осевой силой или изгибающим моментом, действующими на вал - охватываемую деталь 1. Кольцевые пазы расчлен ют сопр женную -поверхность ступицы - охватывающей детали 2, на участки 3, которые воспринимают внещнюю нагрузку, деформиру сь вместе с деталью 1, без проскальзывани , как показано на фиг. I пунктиром.The elastic stationary joint (see 4 | sp. 1) is made for loading conditions with a cyclic axial force or a bending moment acting on the shaft - male part 1. The annular grooves decompose the conjugate-surface of the hub - female part 2, into sections 3, which perceive external load, deformed together with part 1, without slipping, as shown in FIG. I dotted.

В случае нагружени соединени циклическим крут щим моментом пазы на сопр гаемой поверхности -ступицы направлены вдоль оси и образуют участки 3 (см. фиг. 2) в охватывающей детали 2, упруго .деформирующиес совместно с деталью 1 без проскальзывани .If the joint is loaded with a cyclic torque, the grooves on the mating surface of the spline are directed along the axis and form sections 3 (see Fig. 2) in the female part 2, elastically deforming together with the part 1 without slipping.

Данное упругое соединение деталей с нат гом позвол ет повысить долговечность (ресурс) соединени деталей с нат гом и уменьшить металлоемкость конструкции при сохранении уровн внешних силовых факторов.This elastic connection of parts with tension allows to increase the durability (life) of the connection of parts with tension and reduce the metal intensity of the structure while maintaining the level of external force factors.

Claims

1. An elastic connection with a tension containing a female part and a male part, characterized in that, in order to increase the endurance of the compound under cyclic loads, the adjacent surface of the female part is divided into grooves into areas elastically deforming together with the shaft.

2. Connection by and. 1, characterized in that, in order to increase endurance when a cyclic torque is applied to the connection, the grooves are made along the interface by variable depth.

3. Compound according to claim I, characterized in that, in order to increase endurance

connections under the action of cyclic axial force or bending moment, the grooves are made in the form of annular grooves of variable depth.

4. Connection on PP. 2 and 3, characterized in that the depth of the grooves is uniformly reduced in the direction from the end of the female part from the supply side of the load.
