Filter screen structure applied to lubricating oil pump

Abstract

The invention relates to a filter screen structure applied to a lubricating oil pump. The filter screen structure is of an integrated structure and comprises a filter screen and a reinforcing ring, wherein the filter screen is fixed on the reinforcing ring, and the cross section of the filter screen is in a wave shape diffused outwards from a center point of the filter screen; and the wave shape has at least three peaks. The filter screen structure applied to the lubricating oil pump realizes efficient filtration of lubricating oil and has the beneficial effects of the good manufacturability,small size, high strength and high reliability.

Description

technical field [0001] The invention relates to a filter screen structure, in particular to a filter screen structure applied to lubricating oil pumps. Background technique [0002] The lubrication system is an important part of most mechanical systems and plays a decisive role in the normal operation and reliability of the mechanical system. The lubricating oil pump is the core component of the lubrication system. Contamination of the lubricating oil will affect the normal work and operation of the lubricating oil pump. In severe cases, it will cause lubrication blockage, make the system malfunction, and cause accidents. During the research and development and design of aero-engines, in the case of high precision and high lightweight requirements, the size of the filter screen is very small, but its role is very important. At present, most of the filter screens used in lubricating oil pumps have a tapered structure and are installed on the reinforcement ring. The filter sc...

Problems solved by technology

At present, most of the filter screens used in lubricating oil pumps have a tapered structure and are installed on the reinforcement ring. The filter screen is made of wire weaving or drilling on a metal plate. The taper of the filter screen is not guaranteed due to the wire weaving. , when welding the tapered filter screen and the reinforcing ring, it is difficult to operate. At the same time, the filter screen of this structure may have low strength and may be easily broken. However, the mechanically drilled filter screen, the direction of the drilling and the lubricating oil The flow direction is the same, this form is easy to cause cracks and mesh edge delamination problems in the filter screen during processing, and the reliability of use is reduced
