Problems solved by technology

[0003] The traditional high-speed gearbox vent cap directly discharges high-temperature oil and gas into the atmosphere through the vent pipe. Due to the high temperature in the box, the oil and gas discharged into the atmosphere will condense and form oil droplets, which has caused great pollution to the environment.

Abstract

The invention relates to an oil baffle plate for a high-speed gear case vent cap. The oil baffle plate comprises tungsten carbide, montmorillonite, kaolin, bone black, aluminum oxide, magnesium oxide, copper oxide, ferric oxide, AlN, wollastonite, diopside, talcum powder, an anti-aging agent RD, Fe, ferric hydroxide, Al, Zn, Mn, Cr, Ni, Cu, Mo, Ti, Pd, Pt, W, Ce, Eu, Lu, Au, Ag, Sn, Zr, Re and clay. According to the oil baffle plate for the high-speed gear case vent cap, both the bone black and metal raw materials are added into the raw materials, so that the structural strength of the oil baffle plate is improved, heat dispersion of the oil baffle plate is also greatly strengthened compared with that of a pure ceramic material, the condensation efficiency is improved, and thus the oil baffle efficiency of the oil baffle plate is also improved.

Description

technical field [0001] The invention relates to an oil deflector for a vent cap of a high-speed gear box, belonging to the technical field of auto parts. Background technique [0002] Under the condition of high-speed operation, the internal temperature of the gearbox will gradually rise, the gas will continue to expand, and the pressure will continue to increase. In order to allow the thermally expanded air to be discharged freely, to maintain the pressure balance inside and outside the box, so as not to cause the lubricating oil to separate along the box To prevent leakage from other gaps such as surface or shaft seals, and to enhance the sealing effect of the box, it is necessary to install a breather cap on the gearbox. The function of the breather cap is to connect the air in the gear box with the atmosphere outside the box, so as to ensure that the pressure in the box is balanced with the atmospheric pressure. [0003] The traditional high-speed gearbox vent cap direc...
