Abstract

The invention relates to mechanical engineering and can be used to parts connection.The threaded connection with blocking element comprises a bolt (1) with a groove (2), made along its longitudinal axis, a nut (5) with teeth (6), made on one of its side surfaces, and a washer (3), whose outer circumferential surface is made in the form of obliquely arranged petals, and on its inner circumferential surface is made a prominence (4) for engaging the washer (3) with the groove (2) of the bolt (1).

Description

Invenţia se referă la industria constructoare de maşini şi poate fi utilizată pentru îmbinarea pieselor. The invention relates to the machine building industry and can be used for joining parts.

Este cunoscut dispozitivul pentru blocarea piuliţelor, care include un şurub cu o canelură executată de-a lungul axei lui longitudinale, o piuliţă cu o parte laterală dinţată şi un arc de blocare, care uneşte strâns şurubul de piuliţă [1]. A device for locking nuts is known, which includes a screw with a groove made along its longitudinal axis, a nut with a toothed side and a locking spring, which tightly connects the screw to the nut [1].

Dezavantajul acestui dispozitiv constă în complexitatea montării dispozitivului, în special în spaţiile înguste. The disadvantage of this device lies in the complexity of mounting the device, especially in narrow spaces.

Cea mai apropiată soluţie este îmbinarea filetată, care conţine un bolţ, o piuliţă de blocare şi un arc-disc de blocare fixat în piuliţă cu posibilitatea interacţiunii cu partea laterală a bolţului [2]. The closest solution is the threaded joint, which contains a bolt, a lock nut, and a locking disc spring fixed in the nut with the possibility of interaction with the side of the bolt [2].

Dezavantajele acestei îmbinări constau în probabilitatea ridicată de slăbire a piuliţei ca urmare a diferitor influenţe mecanice asupra ei şi a diferenţei de temperatură în timpul funcţionării. The disadvantages of this joint are the high probability of loosening of the nut as a result of various mechanical influences on it and the temperature difference during operation.

Problema pe care o rezolvă invenţia constă în sporirea gradului de siguranţă a îmbinării la blocarea piuliţei. The problem that the invention solves consists in increasing the degree of safety of the joint when locking the nut.

Îmbinarea filetată cu element de blocare, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că include un bolţ cu o canelură, executată de-a lungul axei lui longitudinale, o piuliţă cu nişte dinţi, executaţi pe una din suprafeţele laterale ale ei şi o şaibă, partea exterioară circulară a căreia este executată în formă de lamele amplasate oblic, iar pe partea interioară circulară a ei este executată o proeminenţă pentru cuplarea şaibei cu canelura bolţului. The threaded connection with a locking element, according to the invention, eliminates the above-mentioned disadvantages by including a bolt with a groove, made along its longitudinal axis, a nut with teeth, made on one of its side surfaces and a washer, the outer circular part of which is made in the form of obliquely placed blades, and on its inner circular part a protrusion is made for coupling the washer with the bolt groove.

Invenţia se explică prin desenele din fig. 1-7, care reprezintă: The invention is explained by the drawings in Fig. 1-7, which represent:

- fig. 1, vederea generală a îmbinării filetate cu element de blocare; - Fig. 1, general view of the threaded connection with locking element;

- fig. 2, vederea frontală şi laterală a bolţului; - Fig. 2, front and side view of the bolt;

- fig. 3, vederea frontală şi laterală a şaibei; - Fig. 3, front and side view of the washer;

- fig. 4, vederea frontală şi laterală a piuliţei; - Fig. 4, front and side view of the nut;

- fig. 5, vederea frontală a îmbinării filetate cu element de blocare; - Fig. 5, front view of the threaded connection with locking element;

- fig. 6, îmbinare filetată cu element de blocare, secţiunea A-A; - fig. 6, threaded connection with locking element, section A-A;

- fig. 7, îmbinare filetată cu element de blocare, secţiunea B-B. - Fig. 7, threaded connection with locking element, section B-B.

Îmbinarea filetată cu element de blocare include un bolţ 1 cu o canelură 2, executată de-a lungul axei lui longitudinale, o piuliţă 5 cu nişte dinţi 6, executaţi pe una din suprafeţele laterale ale ei, şi o şaibă 3, partea exterioară circulară a căreia este executată în formă de lamele amplasate oblic, iar pe partea interioară circulară a ei este executată o proeminenţă 4 pentru cuplarea şaibei 3 cu canelura 2 bolţului 1. The threaded connection with a locking element includes a bolt 1 with a groove 2, made along its longitudinal axis, a nut 5 with teeth 6, made on one of its side surfaces, and a washer 3, the outer circular part of which is made in the form of obliquely placed blades, and on its inner circular part a protrusion 4 is made for coupling the washer 3 with the groove 2 of the bolt 1.

Îmbinarea filetată cu element de blocare funcţionează în felul următor. The threaded connection with locking element works as follows.

Prealabil, bolţul 1 este trecut prin orificiile coaxiale ale pieselor de îmbinare 7, apoi din partea opusă, pe bolţul 1, cu posibilitatea amplasării proeminenţei 4 în canelura 2, este îmbrăcată şaiba 3, după care se înşurubează piuliţa 5. Ca rezultat blocarea se realizează datorită angrenării dinţilor 6 de pe piuliţa 5 cu lamelele şaibei 3 şi totodată prin cuplarea şaibei 3 prin intermediul proeminenţei 4 cu canelura 2 a bolţului 1. First, the bolt 1 is passed through the coaxial holes of the connecting parts 7, then from the opposite side, on the bolt 1, with the possibility of placing the protrusion 4 in the groove 2, the washer 3 is put on, after which the nut 5 is screwed on. As a result, the locking is achieved due to the engagement of the teeth 6 on the nut 5 with the blades of the washer 3 and at the same time by the coupling of the washer 3 through the protrusion 4 with the groove 2 of the bolt 1.

Demontarea îmbinării se efectuează prin deşurubarea piuliţei 5 la intensificarea forţei exercitate asupra ei cu scopul ruperii proeminenţei 4 a şaibei 3, fapt ce provoacă slăbirea componentelor îmbinării. Dismantling the joint is carried out by unscrewing the nut 5 while increasing the force exerted on it in order to break the protrusion 4 of the washer 3, which causes the loosening of the joint components.
