Abstract

Использование: машиностроение, узлы креплени с стопорением. Сущность изобретени : устройство содержит подпружиненный в осевом направлении стопорный элемент 4, установленный соосно в двух соединенных резьбой детал х 1 и 2. Один конец стопорного элемента 4 имеет резьбу 5, направление которой противоположно резьбе 3. Дл расширени функциональных возможностей устройства и повышени удобства эксплуатации стопорный элемент 4 ввинчен в резьбовое отверстие 6 детали 1 и подпружинен пружиной 7. Противоположный конец стопорного элемента 4 снабжен шлицами 8 и установлен в отверстие 9 детали 2, выполненное со шлицами. Заходные кромки шлицев выполнены со скосами под углом а, равным углу винтовой линии соедин емых деталей 1 и 2. 3 з.п. ф-лы, 5 ил.Use: mechanical engineering, fixing knots with locking. SUMMARY OF THE INVENTION: The device comprises an axially spring-loaded locking element 4 mounted coaxially in two parts connected by threads 1 and 2. One end of the locking element 4 has a thread 5, the direction of which is opposite to the thread 3. To extend the functionality of the device and increase the ease of operation the element 4 is screwed into the threaded hole 6 of the part 1 and spring-loaded with the spring 7. The opposite end of the locking element 4 is provided with slots 8 and is installed into the hole 9 of the part 2, is made ie with slots. The lead edges of the splines are made with bevels at an angle a equal to the angle of the helix of the parts 1 and 2 being joined. 3 Cp f-ly, 5 ill.

Claims

Claim

1. A fastening assembly comprising a female part that is covered and screwed onto it, as well as an axially spring-loaded locking element coaxially mounted in the said parts, one end of which is made with a thread opposite in direction to the thread on the mating surfaces of the parts and screwed into one of parts, and the opposite threaded end is interfaced with another part, characterized in that, in order to expand functionality and improve ease of use, the opposite threaded end is one hundred ornogo element and its associated surface parts are adapted for engaging elements to prevent their relative-rotation and paired with the possibility of their reciprocal axial movement, wherein the locking element is spring-loaded towards the engagement elements.

2. The node according to claim 1, characterized in that the engagement elements are made in the form of splines.

3. Knot pop. 2, characterized in that the leading edges of the slots are made with a bevel at an angle coinciding in direction with the thread on the parts.

4. The assembly according to claim 3, characterized in that the bevel angle of the entering edges of the splines is equal to the angle of thread rise on the parts.
