Abstract
The utility model discloses a kind of improved circulating pump rectangle broach oil enveloping structure, it is included in the axially arranged rectangle oil sealing tooth of oil sealing axis hole interior edge axis hole, one Oil Guide being in tilted layout gap is set on each rectangle oil sealing tooth of bottom in oil sealing axis hole, and horizontal insertion sets spill port to the rectangle oil sealing tooth bottom on the inside of oil sealing respectively.Rectangle broach oil sealing bottom is processed upper Oil Guide gap by the utility model, the long-pending oil between oil sealing tooth and rotary shaft is retained using the side of Oil Guide gap, and imports spill port, is finally flowed into equipment grease chamber, so as to improve rectangle broach Sealing Performance of Oil Seal, oil liquid leakage is avoided.
Description
Technical field
It the utility model is related to a kind of improved circulating pump rectangle broach oil enveloping structure.
Background technology
The oil sealing of existing slewing is mostly outside framework oil seal formula, Mechanical Sealed Type, felt seal formula, broach oil seal type.Comb
Tooth oil sealing is mostly rectangle broach, triangular comb teeth.1. because the sealing area of rectangle broach and rotary shaft is big, oil sealing tooth is caused
Long-pending oil is formed between rotary shaft, part fluid can flow out with rotary shaft, cause oil liquid leakage.Although 2. triangular comb teeth with
Rotation axis seal area is small, and long-pending oil will not be formed between oil sealing tooth and rotary shaft, but due to sharp at the top of triangular comb teeth, by force
Spend low, easily wear, cause seal clearance bigger than normal, cause oil leak, and repair difficult.
The content of the invention
The purpose of this utility model is to provide a kind of improved circulating pump rectangle broach oil enveloping structure, it is possible to increase rectangle
Broach Sealing Performance of Oil Seal, avoids oil liquid leakage.
The purpose of this utility model is achieved in that a kind of improved circulating pump rectangle broach oil enveloping structure, is included in
The axially arranged rectangle oil sealing tooth of oil sealing axis hole interior edge axis hole, sets on each rectangle oil sealing tooth of bottom in oil sealing axis hole
The Oil Guide a being in tilted layout gap is put, horizontal insertion sets oil return to the rectangle oil sealing tooth bottom on the inside of oil sealing respectively
Hole.
Rectangle broach oil sealing bottom is processed upper Oil Guide gap by the utility model, using Oil Guide gap side by oil sealing tooth with
Long-pending oil retention between rotary shaft, and spill port is imported, finally flow into equipment grease chamber, so as to improve rectangle broach oil sealing sealing
Performance, avoid oil liquid leakage.The utility model works well by trying out.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main view cross-sectional view of the present utility model.
Embodiment
A kind of improved circulating pump rectangle broach oil enveloping structure, it is included in the axially arranged rectangle of oil sealing axis hole interior edge axis hole
Oil sealing tooth 1, the Oil Guide a being in tilted layout gap 3 is set on each rectangle oil sealing tooth of bottom in oil sealing axis hole,
Horizontal insertion sets spill port 4 respectively for rectangle oil sealing tooth bottom on the inside of oil sealing.The utility model is oily by rectangle broach
The upper Oil Guide gap of bottom processing is sealed, is retained the long-pending oil between oil sealing tooth 1 and rotary shaft 2 using two sides of Oil Guide gap 3, and
Spill port 4 is imported, finally flows into equipment grease chamber, so as to improve rectangle broach Sealing Performance of Oil Seal, avoids oil liquid leakage.
