Embodiment Construction

[0023] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0024] A honeycomb sealing structure 100 suitable for gear boxes is a sealing system that combines a honeycomb sealing structure, an oil throwing sealing structure and a separate oil return structure. Under the condition of ensuring sufficient lubrication, the gear can be greatly improved. Oil sealing capacity of the tank. In order to ensure that the bearing 105 is fully lubricated, the honeycomb seal structure 100 suitable for the gearbox also includes a forced lubrication structure.

[0025] The honeycomb sealing structure 100 suitable for a gearbox includes: a bearing bush 101, a stationary ring 102, a transmission shaft 103, a moving ring 104 and a bearing 105; the bearing 105 is sleeved on the outer circumference of the transmission shaft 103 and located in the bearing bush 101; Static ring 102 is positioned at the outer periphery o...

Abstract

The invention discloses a honeycomb type seal structure suitable for a gear box. The honeycomb type seal structure comprises a bearing sleeve, a static ring, a transmission shaft, a moving ring and abearing; the static ring is provided with a shaft opening for the transmission shaft to pass; the moving ring is provided with an oil throwing groove for throwing oil; the static ring is fixed to thebearing sleeve; a whole body consisting of the static ring and the bearing sleeve is provided with a first seal cavity and a second seal cavity; the whole body consisting of the static ring and the bearing sleeve is provided with an oil spraying pipeline for the oil to enter the first seal cavity, a first oil returning channel for the oil to flow back to the interior of the gear box from the firstseal cavity and a second oil returning channel for the oil to flow back to the interior of the gear box from the second seal cavity; a cavity wall of the second seal cavity is provided with a radialhoneycomb belt for increasing the dissipation capacity of an eddy and reducing the circumferential rotational speed of fluid so as to guarantee unobstructed oil returning; an axial honeycomb belt forincreasing on-way resistance to stop oil liquid from leaking outside is further arranged between the static ring and the moving ring. The honeycomb type seal structure suitable for the gear box can beused for effectively improving the oil sealing capacity of the gear box.

Description

technical field [0001] The invention relates to a honeycomb sealing structure, in particular to a honeycomb sealing structure suitable for gear boxes. Background technique [0002] The transmission mechanism of the gearbox needs lubricating oil to ensure the normal operation of the gearbox and prolong the service life of the gearbox. However, the phenomenon of lubricating oil leakage has also become a common problem in the industry. The leakage of lubricating oil directly affects the normal operation of the gearbox, so improving the sealing performance of the gearbox is an important research direction in the current industry. [0003] The existing gearbox sealing structure is relatively simple, which cannot meet the high sealing requirements of the gearbox for normal operation. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the present invention provides a honeycomb sealing structure suitable for gear boxes that can effectively im...
