Abstract

FIELD: machine building.

SUBSTANCE: mechanism comprises a housing with guide bearings, a sliding bar, a shaft with a gear, a wheel pivotally installed in the piston rod, an inside diameter gear rigidly connected to the wheel and kinematically with the gear and an eccentric workpiece. The eccentric workpiece is installed rotatable on the shaft which is kinematically linked to the wheel and is designed to provide permanent-mesh of the inside diameter gear with another gear. At the same time an additional rotatable shaft with an eccentric workpiece is installed in the housing; the shaft is kinematically connected with the wheel and the sliding bar is pivotally connected with the piston rod.

EFFECT: stabilisation of the work process when converting the motion.

Description

The invention relates to converters reciprocating to rotary and vice versa and can be used in internal combustion engines of a piston type.

A mechanism is known from the prior art for converting reciprocating motion into rotational motion, RU 1747777, F16H 21/14, 03/05/1993

A disadvantage of the known mechanism is the unstable (uneven) transmission of rotational motion in the slider positions close to its top dead center.

The problem to which the claimed invention is directed, is to stabilize the process of transferring reciprocating motion into rotational motion with a view to its further industrial application.

The invention is illustrated by drawings, which do not cover, and even more so do not limit the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of its implementation.

The figure 1 shows a General (isometric) view of the proposed mechanism for converting reciprocating motion into rotational in the position of the piston at top dead center.

In figure 2 is a front view with a local section.

In figure 3 is a section aa in figure 2.

The proposed mechanism comprises a housing (1) with straight guides (2), a shaft with a gear (3) mounted rotatably in the housing (1), a wheel (4) pivotally mounted in the connecting rod (5), an internal gear (6) rigidly connected with the wheel (4) and kinematically with the gear (3), an eccentric (7) rotatably on the shaft, kinematically connected with the wheel (4) and designed to ensure permanent engagement of the internal gear (6) with the gear (3 ) To ensure stabilization of the transmission of rotational motion from the internal gear gear (6) to the gear (3), a shaft with an eccentric (8) kinematically connected to the wheel (4) is mounted with the possibility of rotation in the housing (1). Due to the fact that the connecting rod (5) performs plane-parallel oscillatory movements during operation, it is connected to the slider (9) via the axis (10).

The mechanism works as follows: when the slider (9) is reciprocating, the force is transmitted through the hinge (10) to the connecting rod (5), which drives the wheel (4), and the internal gear (6), in turn, rotates gear (3) with a shaft. The internal gear gear (6) is held in constant gear with the gear (3) by means of an eccentric (7) rotating under the influence of the wheel (4) on the gear shaft (3). The eccentric (8), interacting with the wheel (4) and turning in the direction opposite to the direction of rotation of the eccentric (7), gives the wheel (4) an additional rotational movement, which stabilizes the movement of the wheel (4) and prevents it from idling in the connecting rod positions (5 ) close to the top dead center of the slider (9).

Thus, in the claimed invention, while maintaining the advantages of the already known mechanism for converting reciprocating motion into rotational, RU 1747777, which has a significantly higher efficiency compared to the crank mechanism currently used in mechanical engineering, the stabilization of the conversion process is resolved reciprocating motion in rotational and vice versa.
