Description

ми приливами на внешней поверхности или толстостенной.tides on the outer surface or thick-walled.

Муфта работает следующим образом. Вал 4 пускового двигател смещает за счет инерционности ведущую полумуфту 5 по виткам резьбы до упора кольцевого выступа 11 в ведомую полумуфту 2. Полумуфта 2 навинчиваетс на резьбу 3 неподвил ного вала 1 турбины, смеща сь по виткам до упора в заплечико 10. Вал 1 турбины начинает вращатьс как одно целое с валом 4 пускового двигател .The clutch works as follows. Due to inertia, shaft 4 of the starting motor shifts the coupling half 5 along the thread coils up to the stop of the annular protrusion 11 into the driven coupling half 2. The coupling half 2 is screwed onto the thread 3 of the turbine shaft 1, displacing along the turns to the shoulder shoulder 10. The turbine shaft 1 starts rotate as one with the shaft 4 of the starting engine.

После запуска турбины частота вращени вала 1 будет больше частоты вращени вала 4 пускового двигател , поэтому ведуща полумуфта 2, враща сь относительно вала 1 турбины в противоположном направлении переместитс и установитс в нейтральном положении на гладкой кольцевой проточке 9 (вариант I) вала 1 турбины , или перед валом турбины (вариант II).After starting the turbine, the frequency of rotation of shaft 1 will be greater than the frequency of rotation of shaft 4 of the starting engine, therefore the half coupling half 2, rotating relative to shaft 1 of the turbine in the opposite direction, will move and settle in the neutral position on a smooth ring groove 9 (variant I) of turbine shaft 1, or in front of the turbine shaft (option II).

Простота конструкции муфты, состо щей из двух деталей - ведущей и ведомой полумуфт , определ ет надежность ее работы.The simplicity of the two-piece coupling design — the master and the driven coupling halves — determines the reliability of its operation.

Claims

1. Starting clutch containing a leading gear coupling half connected to the drive shaft by means of a multiple thread, and a driven coupling half connected to the driven shaft, characterized in that, in order to increase reliability

and simplifying the design, the leading half coupling is made in the form of a glass with teeth on the inner surface of the walls, the driven shaft is made with a smooth section and a section with a multiple thread, and the driven half coupling is made in the form of a tooth wheel with an internal multiple thread, which engages with the leading half coupling and installed with the possibility of axial movement on the driven shaft, while the threads on the shafts are made with opposite lifting angles.

2. The clutch according to claim 1, characterized in that, in order to reduce losses and

an increase in the service life of a section with multiple threads is made on the end of the driven shaft.
