Embodiment Construction

[0020] The technical solution of the present invention will be described in detail below through a best embodiment in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiment.

[0021] As shown in Figures 1 to 3, an aviation piston engine torsion damping damper includes: a damper housing 2 as an input component, which is connected to a crankshaft through a flat key 1 and rotates together with the crankshaft;

[0022] A reduction gear 10 as an output component, and a fixed ring gear 7 fixedly connected to it;

[0023] The damper housing 2 and the fixed gear ring 7 are attached to each other, and 5 waist-shaped grooves 13 are respectively opened for the insertion of 5 sets of elastic connecting keys. The damper housing 2 is connected by the elastic connecting keys. The torque is transmitted to the reduction gear 10; each group of elastic connecting keys is composed of a pair of spring supports 9 for clamping springs ...

Abstract

The invention discloses an aviation piston type engine driving torsional damper, which at least comprises a damper casing as an input component, a reducing gear as an output component and a fixed gear ring fixedly connected with the reducing gear, wherein the damping casing is connected with a crankshaft and commonly rotates along with the crankshaft; and at least two groups of elastic connecting keys are arranged between the damper casing and the fixed gear ring and are used for transmitting the toque to the reducing gear. By outputting the torque of the crankshaft by using two paths, the driving torsional damper has the functions of damping and increasing the damping, can reduce the torsional rigidity of a combined part of the crankshaft of the engine and a driving system and tunes the inherent frequency of torsional vibration of the driving system.

Description

Technical field [0001] The invention relates to a torsion transmission energy absorption vibration damping device, in particular to a damper for torsion transmission and vibration reduction for the crankshaft power output of an aviation piston engine. Background technique [0002] Aviation piston engine is a high-speed rotating machine, and its vibration problem is a more prominent and difficult to solve. In order to ensure its safe operation, in addition to ensuring careful design and precise manufacturing and installation, dampers are usually used to absorb energy and reduce vibration. And for torque transmission. [0003] The structure of the existing torsion transmission damping damper is as follows: a sleeve configured in the form of a torsion spring is connected to the crankshaft in an anti-rotational manner, and on the crankshaft, an arm in the shape of a beam is axially spaced from a connecting rod. The damping body forms a cavity through an outer shell, and a fluid with a...
