Изобретение относитс к области машиностроени .The invention relates to the field of engineering.
Известны резьбовые шпильки, содержашие стержень с резьбовой и гладкой част ми.Threaded studs are known which contain a rod with threaded and smooth portions.
Недостатком известных шпилек вл етс то, что они не обеспечивают надежности стопорени в резьбовом гнезде с посто нным шагом витков резьбы.A disadvantage of the known studs is that they do not provide reliable locking in the threaded socket with a constant pitch of the threads.
Цель изобретени - повышение надежности стопорени в резьбовом гнезде с посто нным шагом витков резбы.The purpose of the invention is to increase the reliability of locking in a threaded socket with a constant pitch of thread turns.
Дл этого резьбова часть у выходного конца снабжена участком -резьбы в 2-3 витка с шагом, меньшим шага резьбы шпильки.For this, the threaded part at the output end is provided with a 2-3 thread section with a step smaller than the pitch of the stud thread.
На фиг. 1 схематически изображена предлагаема резьбова шпилька; на фиг. 2 - участок резьбы, продольное сечение.FIG. 1 schematically shows the proposed threaded stud; in fig. 2 - thread section, longitudinal section.
Резьбова шпилька состоит из резьбовой I и гладкой 2 частей. Резьбова часть / содержит участок а резьбы с портальным посто нным шагом, соответствуюшим шагу резьбы вThe threaded rod consists of a threaded I and a smooth 2 parts. The threaded part / contains a thread section and a portal with a constant portal pitch corresponding to the thread pitch in
резьбовом гнезде, и участок б прот женность в 2-3 витка с шагом резьбы, меньшим шага резьбы участка а.threaded socket, and section b, the length is 2-3 turns with a thread pitch smaller than the thread pitch of the section a.
Резьбова шпилька ввертываетс в резьбовое гнездо участком а. При дальнейшем ввертывании шпильки участком б первоначально происходит выборка боковых зазоров резьбы на участке а, а затем - заклинивание резьбовой шпильки в гнезде за счет деформации боковых поверхностей резьбы на участке б.The threaded rod is screwed into the threaded socket with section a. Upon further screwing in of the stud with section b, the side gaps of the thread are initially sampled at section a, and then the wedging stud is wedged into the socket due to the deformation of the side surfaces of the thread at section b.
Предмет изобретени Subject invention
Резьбова шпилька, содержаща стержень с резьбовой и гладкой част ми, отличающа с тем, что, с целью повышени надежности стопорени в резьбовом гнезде с посто нным шагом витков резьбы, резьбова часть у выходного конца шпильки выполнена с участком резьбы в 2-3 витка с шагом, меньшим шага основной резьбы шпильки.A threaded rod comprising a rod with threaded and smooth parts, characterized in that, in order to increase the reliability of locking in the threaded socket with a constant pitch of thread turns, the threaded part at the output end of the stud is made with a thread section of 2-3 turns with pitch , smaller pitch of the main thread studs.
