Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be further described:

[0041] Such as Figure 1 to Figure 9 Shown, a kind of air-floating frictionless cylinder of the present invention, it comprises cylinder body and, piston 5 and piston rod 2. That is to say, the cylinder block, the piston 5 and the piston rod 2 constitute the main structure of the present invention, and are generally made of metal materials.

[0042] The cylinder block is composed of a cylinder barrel 8 and a front end cover 9 and a rear end cover 7 fixedly arranged at both ends of the cylinder barrel 8 respectively.

[0043] The front end cover 9 includes a front end cover housing 91 and an air bearing 94 arranged in the front end cover housing 91. A circlip 93 for a hole is provided between the front end of the air bearing 94 and the front end cover housing 91 to Air bearings 94 provide axial positioning. In addition, the rear end of the front cover housing 91 is also ...

Abstract

The invention relates to the technical field of cylinders, in particular to an air floating type friction-free cylinder comprising a cylinder body, a piston and a piston rod. A front end cover comprises a front end cover shell and an air bearing, the front end cover shell is provided with a bearing air inlet and a front end air inlet, a rear end cover comprises a rear end cover shell which is provided with a rear end air inlet, the piston rod penetrates through the air bearing to be connected with the piston which consists of a piston main body, the piston front end cover and the piston rear end cover, a plurality of vent holes are arranged in the periphery direction of the piston main body and are internally provided with air nozzles, and the piston front end cover and the piston rear end cover are provided with check valve mechanisms. For the air floating type friction-free cylinder, friction between the piston rod and the front end cover is avoided by the air bearing effectively, and friction between the outer wall of the piston and the inner wall of a cylinder barrel of the cylinder is avoided by the piston with the vent holes, the working efficiency is improved greatly, and the energy consumption is saved.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to an air-floating frictionless cylinder. Background technique [0002] Cylinders are widely used in various fields, but there are different degrees of contact friction between the piston seal ring of the existing cylinder and the cylinder barrel, as well as between the piston rod and the dust seal, which greatly affects its working efficiency. In order to effectively reduce the friction of the cylinder, improve work efficiency and reduce energy consumption, many meaningful explorations have been made in the industry, such as: 1. Improve the machining accuracy of the cylinder; 2. Use special grease; 3. Use materials with a small friction coefficient Wait. Although the above-mentioned series of methods can reduce the frictional force of the cylinder to a certain extent and reduce energy loss, they still cannot completely solve the problem of frictional force, and the processing co...
