Description

Technical Field

[0001] The invention relates to the technical field of mechanical transmission, in particular to a large radial displacement compensating rubber elastic element and an assembling method thereof. Background Art

[0002] The rubber elastic element is an important component of the high elastic coupling and has the ability to compensate for radial displacement. The radial displacement compensation capacity depends on the outer diameter, inner diameter and length of the rubber elastic element; the length of the rubber elastic element is subject to the working speed of the rubber elastic element. The rubber elastic element cannot be too long, otherwise it will easily lead to instability and the rubber will be thrown out. When the elastic coupling has high requirements for radial displacement compensation and working speed, the following contradiction will arise: when large radial displacement compensation is to be met (using a long rubber elastic element), the working speed cannot meet the requirements; and when the working speed is to be met, the radial displacement compensation cannot meet the requirements. At this time, double-row rubber elastic elements are generally connected in series at the same time, which can meet the requirements of working speed and large radial displacement compensation, but this method will greatly increase the weight of the coupling and cannot meet the requirements of lightweight. This requires the design of a new type of large displacement compensation rubber elastic element, which can simultaneously meet the requirements of working speed, radial displacement compensation and lightweight of the high elastic coupling.
