Problems solved by technology

However, at present, the inner cavity of the hydraulic cylinder is generally circular. When the strength meets the requirements, the circular shape has a large size and takes up a lot of space. It is easy to interfere with other parts, which is not conducive to installation, but also Make the weight and volume of the entire hydraulic system too large

Embodiment Construction

[0011] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] Depend on Figure 1-Figure 2 It can be seen that the present invention includes a cylinder 2, a front cylinder cover 1, a rear cylinder cover 5, a piston 3 and a piston rod 6, the front cylinder cover 1 and the rear cylinder cover 5 are located at both ends of the cylinder 2 respectively, and the piston 3 is sleeved on the cylinder 2 Inside, the piston rod 6 is connected with the piston through the fixing nut 4 and then passes through the rear cylinder head 5, and the inner cavity profile of the cylinder barrel 2 is elliptical.

[0013] The inner cavity profile of the cylinder 2 of the present invention is elliptical, which can reduce the size of the hydraulic cylinder in the radial direction, and facilitate the installation and arrangement of peripheral hydraulic components. Although it is an elliptical shape, the size in the radial dir...

Abstract

The invention relates to an elliptical hydraulic cylinder. The elliptical hydraulic cylinder comprises a cylinder barrel, a front cylinder cover, a rear cylinder cover, a piston and a piston rod, wherein the front cylinder cover and the rear cylinder cover are positioned at two ends of the cylinder barrel respectively, the piston is sleeved inside the cylinder barrel, the piston rod is connected with the piston through a retaining nut prior to penetrating through the rear cylinder cover, and the inner chamber profile of the cylinder barrel is elliptical. The elliptical hydraulic cylinder is reasonable and simple in structural design and low in manufacture difficulty and cost, and the size of the hydraulic cylinder in the radial direction can be decreased while peripheral hydraulic parts are mounted and arranged conveniently by the aid of an elliptical inner chamber of the cylinder barrel. Though the size of the hydraulic cylinder in the radial direction is decreased due to the elliptical profile, the elliptical hydraulic cylinder still meets the strength requirements by means of strict strength design, and the elliptical hydraulic cylinder is high in reliability.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to an oval hydraulic cylinder which is easy to install. Background technique [0002] At present, the hydraulic cylinder is an important transmission component and one of the important accessories of the hydraulic system. However, at present, the inner cavity of the hydraulic cylinder is generally circular. When the strength meets the requirements, the circular shape has a large size and takes up a lot of space. It is easy to interfere with other parts, which is not conducive to installation, but also Make the weight and volume of the whole hydraulic system too large. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide an elliptical hydraulic cylinder with simple structure, reasonable design, small volume, easy installation and meeting the strength requirements. [0004] In order to achiev...
