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 environment-friendly vent cap for a high-speed gearbox. The environment-friendly vent cap comprises a vent hood, a vent pipe and a base, the vent hood and the upper end of the vent pipe are fixedly connected, and the base and the lower end of the vent pipe are fixedly connected; a cavity is formed in a hood body at the upper end of the vent hood, a vent hood connection portion is formed at the lower end of the vent hood, the vent hood is provided with an exhaust port, and a foam copper filter screen is arranged at the exhaust port; a gas and oil separator is arranged at the upper end in the vent pipe, oil baffle plates are arranged at the lower end in the vent pipe, and a first oil return pipeline is arranged in the vent pipe; a second oil return pipeline is arranged in the base and communicated with the first oil return pipeline, and the vent pipe is wrapped by a clamp jacket communicated with a circulating water pump. According to the environment-friendly vent cap for the high-speed gearbox, by means of multiple cooperation of the foam copper filter screen, the gas and oil separator and the oil baffle plates, oil gas in high-temperature gas exhausted from the high-speed gearbox can be effectively intercepted, the oil gas in exhausted gas is greatly reduced, environment pollution is reduced, and the environmental protection effect is significant.

Description

technical field [0001] The invention relates to an environment-friendly ventilation cap for 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 ...
