Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] Such as Figure 1 to Figure 3 As shown, the transmission device includes an outer cylinder 1 made of metal and an inner cylinder 2 made of metal. The shapes of the outer cylinder 1 and the inner cylinder 2 can be determined according to actual needs. In the example shown in the figure, both the outer cylinder 1 and the inner cylinder 2 are circular. The outer cylinder 1 is provided with a first cylinder chamber 11 ; the inner cylinder 2 is provided with a second cylinder chamber 21 . The first barrel cavity 11 is coaxially arranged with the second barrel cavity 21 . The inner cylinder is movably arranged in the first cylinder chamber of the outer cylinder, preferably, the inner cylinder 2 is slidably arranged in the first cylinder chamber 11 . A fiber-reinforced resin or fiber-reinforced plastic cylinder 22 is disposed in the second cavity 21 of the inner cylinder 2...

Abstract

The invention discloses a transmission device which comprises an outer barrel and an inner barrel. A first barrel cavity is formed in the outer barrel. A second barrel cavity is formed in the inner barrel. The inner barrel is movably arranged inside the first barrel cavity of the outer barrel. The transmission device is characterized in that fiber-reinforced resin or a fiber-reinforced barrel is arranged inside the second barrel cavity of the inner barrel, and the fiber-reinforced resin or the fiber-reinforced barrel is connected with the inner barrel. Compared with a pure-metal transmission device, the weight of the transmission device can be lowered by over 30 percent under the condition that the rigidity and strength of the transmission device and those of the pure-metal transmission device are equal.

Description

technical field [0001] The invention relates to a transmission device. Background technique [0002] The current transmission device used for actuators or buffers has a structure including an inner cylinder and an outer cylinder; the inner cylinder is movably arranged in the outer cylinder. This structure has high requirements on the fatigue performance, corrosion resistance and impact resistance of the material. Both the outer cylinder and the inner cylinder are metal cylinders. Therefore, in order to meet various performance requirements of the structure, the thickness of the cylinder must be thick enough. One of its disadvantages is that the thick cylinder is relatively heavy, which cannot meet the requirement of light weight. For aircraft, weight is one of its important metrics. Reducing the weight of an aircraft increases its carrying capacity. However, the use of parts made of metal materials will undoubtedly make it difficult to reduce its own weight. Contents o...
