Description
Technical field
This utility model belongs to reductor equipment technical field, specifically a kind of double-mechanical labyrinth combined seal structure.
Background technology
Reductor leakage of oil is one of FAQs, because leakage of oil can cause other serious consequences such as burn-out of bearing.The sealing of reductor at present mainly uses outside framework oil seal contact seal, reductor seal failure to be primarily due to oil sealing and there occurs abrasive wear, cause seal failure.And the source one of abrasive particle is the coal dust in external environment condition and other graininess dust, two is that in lubricating oil, graininess impurity enters oil seal lip.How to reduce and even avoid dust to invade oil seal lip, extend sealing life and just become an industry difficult problem.
Summary of the invention
This utility model is in order to solve reductor Leakage, it is provided that a kind of double-mechanical labyrinth combined seal structure.
This utility model takes techniques below scheme: a kind of double-mechanical labyrinth combined seal structure, end cap including decelerator, outside framework oil seal installation cavity is set in end cap, it is provided with outside framework oil seal in outside framework oil seal installation cavity, outside framework oil seal installation cavity is provided with pouring orifice, end cap left end is provided with the radial labyrinth groove connected with outside framework oil seal installation cavity, and end cap right-hand member is provided with the axial labyrinth groove connected with outside framework oil seal installation cavity.Axially being applied in combination of labyrinth and radial labyrinth and traditional outside framework oil seal；Maze trough can repairing at any time, intercepted inside and outside portion dust granules by double-mechanical maze trough and entered oil seal lip, extended the service life of sealing member.
Compared with prior art, this utility model has the advantages that
1. seal structure and add two-way mechanical type labyrinth seal, intercepted the granule being mingled with in internal lubrication oil and external particle enters outside framework oil seal lip, made outside framework oil seal be in normal operating conditions, increase the service life.
2. this sealing simple in construction, processing and manufacturing is easy for installation, easily realizes.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
1-pouring orifice in figure, 2-oils and fats, 3-axial labyrinth groove, 4-outside framework oil seal, 5-radial labyrinth groove.
Detailed description of the invention
As shown in Figure 1, a kind of double-mechanical labyrinth combined seal structure, end cap including decelerator, outside framework oil seal installation cavity is set in end cap, outside framework oil seal 4 it is provided with in outside framework oil seal installation cavity, outside framework oil seal installation cavity is provided with pouring orifice 1, and end cap left end is provided with the radial labyrinth groove 5 connected with outside framework oil seal installation cavity, and end cap right-hand member is provided with the axial labyrinth groove 3 connected with outside framework oil seal installation cavity.
Claims (1)
