Description
Изобретение относитс к области машиностроени . Известно устройство дл уравновен1ивани центрального кривошипно-шатунного механизма, содержащее станину, коленчатый вал, четыре зубчатых колеса с нротивовесами , установленные на станине, и паразитные зубчатые колеса, передающие враП1ение от кривошипа механизма, одно из которых установлено на коленчатом валу 1. Недостатком указанного устройства вл етс его кинематическа сложность. Наиболее близким по технической сущности вл етс устройство дл уравновещивани центрального кривоп иг1но-п1атунного механизма, содержащее корпус, четыре зубчатых колеса, два из которых предназначены дл установки на коленчатом валу механизма симметрично относительно плоскости движени его звеньев, а два других, ведомых , - на корпусе и попарно наход тс в зацеплении с первыми, оси вращени ведомых колес расположены в плоскости, отсто щей от оси вращени коленчатого вала на рассто нии, выбираемом из услови уравновещивани первой гармоники суммарного неуравновешенного момента механизма , и противовесы, закрепленные на коленчатом валу и зубчатых колесах 2. Однако при соосном расположении ведомых колес, межосевое рассто ние, выбираемое из услови уравновешивани первой гармоники суммарного неуравновешенного момента механизма, может оказатьс недопустимо мало, что приведет к ненормальным услови м работы кинематической нары и тем самым к снижению долговечности механизма. Целью изобретенн вл етс повышение долговечности устройства. Это достигаетс тем, что ведомые колеса расположен)1 по разш51е стороны и на равном рассто нии от плоскости, проход щей через ось вращени коленчатого вала и. ось качани шатуна. На фи-. 1 изображена кинематическа схема устройства дл уравновен1ивани кривощштно-щатунного механизма; на фиг. 2 - вид стрелки А фиг. .1. На коленчатом валу 1, расположенном в корпусе 2, установлены два зубчатых колеса 3 и 4 симметрично-относительно плосThe invention relates to the field of engineering. A device is known for balancing a central crank mechanism, comprising a frame, a crankshaft, four gears with counterweights mounted on the frame, and parasitic gears that transmit the rotation from the crank of the mechanism, one of which is mounted on the crankshaft 1. The disadvantage of this device is its kinematic complexity. The closest in technical essence is a device for balancing the central curvature of a puncture mechanism, comprising a housing, four gears, two of which are designed to be mounted on the crankshaft of the mechanism symmetrically with respect to the plane of movement of its links, and are in pairs in engagement with the first ones, the axes of rotation of the driven wheels are located in a plane spaced from the axis of rotation of the crankshaft at a distance chosen from the condition of balancing the first the harmonics of the total unbalanced moment of the mechanism, and the counterweights attached to the crankshaft and gears 2. However, when the driven wheels are coaxially positioned, the axial distance selected from the condition of balancing the first harmonic of the total unbalanced moment of the mechanism may be unacceptably small, resulting in abnormal conditions m of operation of the kinematic plank and thus to reduce the durability of the mechanism. The purpose of the invention is to increase the durability of the device. This is achieved in that the driven wheels are located) 1 on the raschny e side and at equal distance from the plane passing through the axis of rotation of the crankshaft and. axle swing rod. On fi-. 1 shows a kinematic diagram of a device for balancing a crank-rod-and-rod mechanism; in fig. 2 is a view of arrow A of FIG. .one. On the crankshaft 1, located in the housing 2, there are two gears 3 and 4 mounted symmetrically relatively flat
