Problems solved by technology

[0002] As a power transmission device, gearboxes are widely used in industrial production and transportation tools. Due to the meshing of multiple gears in the gearbox during work, a lot of heat will be generated. With the increase of heat, the temperature inside the gearbox will increase. It will cause the pressure in the gearbox to increase, which will cause the lubricating oil to seep from the box surface. At the same time, due to the high speed of the gear during the transmission process, some lubricating oil will be continuously splashed. When the drops meet the high temperature in the tank, a large amount of oil mist will be generated, and the conventional vent cap is difficult to contain the discharge of this oil mist

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with accompanying drawing, so that those skilled in the art can understand more clearly, as figure 1 As shown, the present invention includes:

[0016] The ventilation pipe 1, the bottom end of the ventilation pipe 1 extends radially outwards to form an annular extension portion, and the annular extension portion evenly distributes a number of through holes along the circumferential direction, and the inner peripheral surface of the upper end of the ventilation pipe 1 is provided with a ventilation pipe 1. Pipe internal thread;

[0017] Connected to the gland 2 on the upper end of the vent pipe 1, the lower part of the gland 2 is a cylinder, and the peripheral surface of the cylinder is provided with an external thread of the gland, and the external thread of the gland is threaded to the internal thread of the vent pipe. The upper part of the gland 2 is a polygonal boss, and the center of th...

Abstract

The invention discloses a gear case vent cap. The gear case vent cap comprises a breather pipe, a gland connected to the upper end of the breather pipe, an intermediate shaft connected to the bottom surface of the gland, a plurality of flow guide plates spirally distributed on the peripheral surface of the intermediate shaft from top to bottom and arranged spirally and obliquely and a dust cap connected to the upper end of the gland. The inner diameter of an annular groove of the dust cap is slightly greater than the outer diameter of the upper end of the breather pipe, so that a gap is reserved between the inner peripheral surface of the annular groove and the outer peripheral surface of the breather pipe. The gear case vent cap can effectively relieve discharge of oil mist and prevent oil drops from being thrown out and can also make oil flow back to a gear case. Resources are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of transmission, and in particular relates to a gear box vent cap. Background technique [0002] As a power transmission device, gearboxes are widely used in industrial production and transportation tools.

It will cause the pressure in the gearbox to increase, which will cause the lubricating oil to seep from the box surface. At the same time, due to the high speed of the gear during the transmission process, some lubricating oil will be continuously splashed. When the droplets meet the high temperature in the tank, a large amount of oil mist will be generated, and it is difficult for conventional vent caps to contain the discharge of this oil mist. Contents of the invention [0003] In order to solve the above existing problems, the...
