Изобретение относитс к машиностроению , а именно к храповым механизмам .This invention relates to mechanical engineering, in particular to ratchet mechanisms.

Целью изобретени вл етс повьппе ние надежности за счет обеспечени посто нного контакта одной из двух собачек с храповым колесом.The aim of the invention is to increase reliability by ensuring that one of the two dogs is in constant contact with the ratchet wheel.

На фиг.1 изображен безударный храповой механизм, общий вид на фиг.2- вид А на фиг. 141 shows an impact-free ratchet mechanism, the general view of FIG. 2 is view A of FIG. 14

Безударный храповой механизм содержит храповое колесо 1, направл ющие 2 и 3, размещенные в них ползуны 4 и 5 с пальцами 6 и 7 и собачками 8 9 дЛ взаимодействи с храдовым колесом 1, подвижный в окружном направлении кулачок 10 с замкнутыми пазами 11 и 12, причем один из них смещен по фазе относительно другого, дл взаимодействи с пальцами 6, 7 предварительно закрученную пружину 13, св занную с кулачком 10, устройством 14 ее закручивани . ,The unstressed ratchet mechanism contains a ratchet wheel 1, guides 2 and 3, sliders 4 and 5 placed in them with fingers 6 and 7 and dogs 8 9 dL interacting with the storage wheel 1, the cam 10 moving in a circumferential direction with closed grooves 11 and 12, and one of them is out of phase with respect to the other, in order to interact with the fingers 6, 7, the pre-twisted spring 13 connected with the cam 10, the device 14 of its twisting. ,

Безударный храповой механизм рабо- 25 °P предварительно закрученной пружины обеспечивает устройство 14 закручивани пружины.The unstressed ratchet mechanism of the 25 ° P pre-twisted spring provides a spring-tightening device 14.

Invention Formula

A shock-free ratchet mechanism comprising a ratchet wheel, a guide, a slider placed in it with a finger and a pawl for interacting with the ratchet wheel, moving in a circle as follows.

Under the action of a pre-twisted spring, the cam 10, the closed groove 11; rotates the finger b with the dog 8, moves it to the left along the guide 2 and the dog 8 enters the interaction with the ratchet wheel 1, at the same time the closed groove 12, acting on the finger 7 of the slider 5 with the pawl 9, moves it to the right, disengaging from the ratchet wheel 1 the pawl 9. The ratchet wheel can only rotate counterclockwise, and the pawl 8 prevents it from turning clockwise.

When the ratchet wheel 1 rotates counterclockwise due to the displacement of the closed grooves 11, 12 in phase of the groove 11 of the cam 10, I will affect the finger 6 of the slide 4 with the dog 8, move it to the left along the guide 2, ensuring a constant the interaction of the dog 8 with the ratchet wheel 1 "a

In the 3 rd direction, a cam with a groove for interacting with a finger, is used in order to ensure reliability, the groove is closed, the mechanism is equipped with a pre-twisted spring connected to the cam, and a device for twisting it , an additional guide and additional finger and dog slider positioned in it, and in the cam there is a second closed slot coaxial with the first one and shifted in phase relative to the first one to interact with the finger of the additional slider.

The groove 12 of the cam 10, acting on the finger 7 of the slide 5 with the dog 9, moves it to the right along the guide 3 to its beginning. Upon further rotation of the ratchet wheel 1, the cam 10, acting with the groove 12 on the finger 7 of the slide 5 with the dog 9, moves it along the guide 3 to the left and the dog 9 engages with the ratchet wheel 1. At the same time, the closed groove 11 acts on the finger 6, the slider 4 with the dog 8, moves it to the right, disengages from the ratchet with the forest the dog 8, the slider 4 reverses along the guide 2, and the pallet 6 moves to the left along the guide 3, ensuring the interaction of the dog 9 with a ratchet wheel 1. Next, the cycle repeats, thus ensuring There is a variable interaction of dogs 8, 9 with the ratchet wheel 1, ensuring a constant contact of one of them with the ratchet wheel 1. Compensation of the distance

A shock-free ratchet mechanism containing a ratchet wheel, a guide, a slider placed in it with a finger and a pawl for interacting with the ratchet wheel, moving around

In this direction, a cam with a groove for interacting with a finger, is made so that, in order to ensure reliability, the groove is made closed, the mechanism is provided with a pre-twisted spring connected to the cam, a device for its twisting, an additional guide and additional fingers and a dog placed in it, and in the cam there is a second closed groove coaxial with the first one and shifted in phase with the first one to interact with the finger of the additional slide.
