Squeeze film damper for transmission shafting

Abstract

The invention relates to a squeeze film damper for a transmission shafting, which comprises a shaft, wherein the external circumference of the shaft is sleeved by an inner damper ring with a groove in the circumference, an outer damper ring is arranged in the groove in the circumference of the inner damper ring, an oil chamber is formed between the outer damper ring and the inner damper ring, lubricant oil is placed in the oil chamber; both ends of the oil chamber are sealed by seal rings; and a notch of the groove of the inner damper ring is connected with both end faces of the outer damper ring through connecting pieces. The squeeze film damper is simple in structure, an independent mechanism is adopted to realize the damper, the squeeze film damper is convenient in fabrication and installation, can be arranged at any position in the shafting, and has a good damping effect, and the installation and operation of the squeeze film damper are not limited.

Description

technical field [0001] The invention relates to the technical field of damping and vibration reduction, in particular to a squeeze oil film damper used on a transmission shaft system. Background technique [0002] A damper is a device that provides resistance to movement and consumes movement energy. Damping is used to absorb energy and reduce vibration. In the technical field of vibration reduction of rotating machinery, squeeze oil film damper is a new type of damping shock absorber, which has the characteristics of simple structure, less space, easy manufacture, and remarkable vibration reduction effect. , Widely used in aerospace, aviation, military industry, guns, automobiles and other industries. [0003] The extrusion oil film damping shock absorber in the prior art usually adopts the interference fit between the outer ring of the rolling bearing or the sliding bearing and the bearing seat to be changed to a clearance fit, and the gap is filled with flowing lubricati...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the shortcomings of the extrusion oil film damper in the above-mentioned existing production technology, such as installation limitations and inconvenient installation, the applicant provides a transmission shaft extrusion oil film damper with a reasonable structure and easy operation, so that it does not need to rely on The bearing adopts an independent mechanism, which can be easily installed on any position on the shaft system with installation space, and has a good damping and vibration reduction effect
