Description
Technical Field
The utility model belongs to the technical field of it is sealed, mainly relate to a high-speed gear box leak protection oil seal structure.
Background
Due to the defects in the aspect of structural design, the input and output transparent covers of the existing high-speed gearbox are mutually and directly contacted by matching framework oil seals, various problems are obvious after the gearbox is used for a period of time, the main focus is on the following conditions, when the gearbox runs, an oil film cannot be formed due to the fact that lubrication is not performed between a rear oil seal in the matching oil seal and a shaft, the oil seal with too high temperature is damaged quickly, after the gearbox is used for a period of time, the lubricating oil leaks due to the fact that the matching framework oil seal is damaged, the maintenance cost is high, and the environment is polluted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems existing in the prior art, researching and developing a high-speed gear box leakage-proof oil sealing structure, and achieving the purposes of improving the oil seal operation efficiency and reducing the environmental pollution.
The utility model aims at realizing that a high-speed gear box leak protection oil seal structure includes that transmission shaft, bearing oil blanket, oil return opening, lubricating oil baffle, oil slinger, broach are sealed, deep bead and distance ring combination have improved the inside leakproofness of high-speed gear box, have guaranteed the long-term operation of equipment, have prolonged the life of equipment, have that structural design is novel, reasonable, overall structure is compact, use reliable, adaptability is strong characteristics.
Drawings
FIG. 1 is a view of the oil leakage seal structure of a high speed gearbox;
description of part numbers in the figures: 1. the oil slinger comprises a wind shield, 2, a distance ring, 3, a comb seal, 4, an oil slinger, 5, a lubricating oil baffle, 6, an inner distance ring, 7, a sliding bearing, 8, an oil return port, 9, a transmission shaft, 10 and a bearing oil seal.
Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. This high-speed gear box leak protection oil seal structure includes box 11, transmission shaft 9, slide bearing 7 suit cooperates on box 1 and transmission shaft 9, wherein bearing oil blanket 10 suit carries out clearance fit in slide bearing 7 both sides respectively, lubricating oil baffle 5 fixes through bolted connection and interior position ring 6 and bearing oil blanket 10, oil slinger 4 suit has certain clearance in the outside of lubricating oil baffle 5, the broach in the lubricating oil baffle 5 outside is sealed 3, broach is sealed 3 and is fixed and cooperate with transmission shaft 9 through the tongue of self and the recess of box 11, deep bead 1 and the outer distance ring 2 in the box 11 outside are fixed through bolted connection and box 11.
During operation, lubricating oil forms certain smooth oil film through slide bearing 7 and high-speed rotatory transmission shaft 9, unnecessary lubricating oil guarantees the formation of smooth oil film through bearing oil seal 10 when being thrown away, the lubricating oil that is thrown away blocks through lubricating oil baffle 5 and gets into oil return opening 8, the lubricating oil that is not blockked by the lubricating oil baffle can be blockked when passing through oil slinger 4, the lubricating oil that is not blockked by the oil slinger, can be furthered when being thrown away to broach seal 3, deep bead 1 also has certain wind-shielding effect simultaneously, guarantee the operation effect.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
