Abstract

FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to design of chain gears. Wedge transmission round-link chain comprises chain and pulleys. Groove pulleys are equipped with friction linings. One of chain links in contact simultaneously with two side surfaces of pulley, and adjacent to it link-only on one side surface.
EFFECT: expanded scope of application is achieved.

Description

Известна клиновая передача, состоящая из шкивов по ГОСТ 20889-88 и клинового ремня по ГОСТ 1284.1-89.A wedge gear is known, consisting of pulleys according to GOST 20889-88 and a V-belt according to GOST 1284.1-89.

Недостатком данной передачи является относительно небольшой срок службы ремней, крайняя нежелательность их перегиба в противоположную сторону, невозможность изменения длины приводного элемента, относительно малые передаваемые усилия при высоком предварительном натяжении, и больших диаметрах шкивов.The disadvantage of this transmission is the relatively short service life of the belts, the extreme undesirability of bending them in the opposite direction, the inability to change the length of the drive element, the relatively small transmitted forces with high pre-tension, and large diameters of the pulleys.

Указанные недостатки устраняются путем применения в качестве передающего органа круглозвенной цепи вместо клинового ремня. Кроме того, боковые поверхности канавок шкивов оснащены накладками из фрикционного материала. При этом при работе передачи одно из звеньев круглозвенной цепи одновременно контактирует с обеими боковыми поверхностями раздвижных или нераздвижных канавок, а соседнее с ним в то же время только с одной боковой поверхностью канавки.These shortcomings are eliminated by using a round link chain as a transmitting organ instead of a V-belt. In addition, the side surfaces of the pulley grooves are equipped with friction material pads. At the same time, during transmission operation, one of the links of the round link chain is in contact with both lateral surfaces of the sliding or non-sliding grooves, and adjacent to it at the same time with only one side surface of the groove.

На фиг. 1 показана схема зацепления круглозвенной цепи 1 с канавкой шкива 2, боковые поверхности которой оснащены фрикционными накладками 3, и которая может быть, например, раздвижной.In FIG. 1 shows a gearing scheme for a round link chain 1 with a pulley groove 2, the side surfaces of which are equipped with friction linings 3, and which can be, for example, sliding.

Преимуществом такой передачи является использование в сельскохозяйственной технике единого типа передач энергии между удаленными валами, кроме того, обеспечивается многократное увеличение долговечности передающего органа в сравнении с клиновыми ремнями, уменьшаются диаметры шкивов, имеется возможность изменения длины приводного элемента при некотором удешевлении ценовых параметров.The advantage of such a transfer is the use in agricultural machinery of a single type of energy transfer between the remote shafts, in addition, a multiple increase in the durability of the transmitting body in comparison with V-belts, the pulley diameters are reduced, there is the possibility of changing the length of the drive element with some reduction in price parameters.

Изобретение относится к общему машиностроению, к конструкции приводных передач и может быть использовано в приводах рабочих органов, например, сельскохозяйственных машин и орудий, а также в других отраслях.The invention relates to general mechanical engineering, to the design of drive gears and can be used in drives of working bodies, for example, agricultural machines and implements, as well as in other industries.
