Изобретение относитс к общему машиностроению и может использоватьс дл осуществлени периодического поворота с выстоем рабочих органов стаиков и машии.The invention relates to general engineering and can be used to carry out periodic rotation, with an overhang, of the working bodies of the staff and machines.

Дл осуществлеии периодического вращеии с различными отношени ми времени поворота ко времеии высто могут использоватьс мальтийские механизмы, содержащие привод, мальтийский крест, кривошип с пальцем , взаимодействующий с пазами креста, и зубчатую передачу с эллиптическими колесами , соедин ющую привод с кривошипом.Maltese mechanisms containing a drive, a Maltese cross, a finger crank, interacting with the grooves of the cross, and a gear drive with elliptical wheels, connecting the drive with the crank, can be used to perform periodic rotation with different ratios of turning the time.

Недостатками мальтийских механизмов с эллиптическими зубчатыми колесами вл ютс узкий диапазон измеиени отношени времеии поворота ко времени высто мальтийского креста и сложность изготовлени эллиптических кОлес.The disadvantages of the Maltese gears with elliptical gears are the narrow range of changes in the ratio of the turning time to the time of the Maltese cross and the difficulty of making elliptical clocks.

Наиболее близким по технической сущности и достигаемому эффекту к изобретеиию вл етс мальтийский механизм, содержащий привод, мальтийский крест, кривощип с пальцем, взаимодействующим с пазами креста, и диффереициал, один из ведущих элементов которого соединен с приводом , а ведомый - с кривощипом. Второй ведущий элемент дифференциала взаимодействует с эксцентриковым механизмом с переменным эксцентриситетом, который позвол ет регулировать отношение времеии поворота ко времени высто креста.The closest in technical essence and the achieved effect to the invention is the Maltese mechanism, which contains a drive, a Maltese cross, a curved wheel with a finger interacting with the grooves of the cross, and a differential, one of the leading elements of which is connected to the drive, and the slave - with a curved wheel. The second driving element of the differential interacts with the eccentric eccentric mechanism, which allows the ratio of the rotation time to the height of the cross to be adjusted.

Данный механизм позвол ет измен ть от: ношение времени поворота креста ко времени высто лишь в 2-3 раза, а кроме того , имеет сложную конструкцию.This mechanism allows to change from: wearing the time of turning the cross to time only 2-3 times, and in addition, has a complex structure.

Дл расширени диапазона, изменени отношени в ремеии поворота ко времени высто мальтийского креста и упрощени коиструкции второй ведущий элемент дифференциала кинематически св зан с мальтийским крестом.To broaden the range, change the ratio in the turn to time of the Maltese cross and simplify the conversion, the second leading element of the differential is kinematically connected with the Maltese cross.

На фиг,. I дана кииематическа схема мальтийского механизма; на фиг. 2 показано то же, вариант его выполиеиие.In FIG. I have given the mathematical scheme of the Maltese mechanism; in fig. 2 shows the same, option it vypoliiiye.

Claims

The Maltese mechanism contains a drive (not shown), a Maltese cross I, a crank 2 with a finger 3 interacting with the grooves of the cross I, a differential, one central wheel 5 connected to the Maltese cross I using gear 6 and a rigid gear on the axis of the cross i. rigidly connected with the central gear wheel 5 of the gear 7, and the carrier 8, carrying the interacting with the central wheels 4 and 5, the satellites 9, is connected to the crank

2. The Maltese mechanism works as follows. During the period of idle rotation of the crank 2, the Maltese cross 1 through gears 6 and 7 brakes the central wheel 5, and the differential works as a planetary gearbox. When the finger 3 enters the groove of the cross 1 and turns it, the central wheel 5 is released. The rotation of the central wheel 5 accelerates or slows down (in the latter case, a parasitic wheel must be set between gears 6 and 7). Crankshaft 2, i.e. speeds up or slows down the rotation of the cross I. The mechanism may have another embodiment, in which; The rum (as shown in Fig. 2) the driving elements of the differential are the central wheel 4 connected to the drive and the central wheel 5 connected to the crank 3, and the follower is the carrier 8 kinematically connected through gears 6 and 7 to the Maltese the cross I. The Maltese mechanism described has an inorganic range of changes in the ratio of the turning time to the time of the Maltese cross and is characterized by simplicity of design. Claims of invention The Maltese mechanism, comprising a drive, a Maltese cross, a crank with a finger interacting with the grooves of the cross, and a differential, one of the leading elements of which is connected to the drive, and the slave is connected to a crank, characterized in that turning the Maltese cross to time and simplifying the design, the second leading element of the differential is kinematically connected with the Maltese cross.
