Abstract
The water pump oil shield leak-proof structure. The crude oil gear is in a structure form of three dynamic and static combinations, the dynamic ring is driven to rotate by extrusion force generated by the O-shaped ring between the dynamic ring and the shaft, the internal mechanism is complex, and long-time operation leads the inside to generate oil sludge, so that the friction force between the dynamic ring and the static ring is increased. The composition of the utility model comprises: the oil splash device comprises a bearing body (6) and a shaft (7), wherein an oil baffle (1) is arranged in the bearing body, the shaft and a splash ring (4) are fixed through jackscrews (2), and teeth of an inner ring of the oil baffle and teeth of an outer ring of the splash ring are distributed in a staggered mode to form a labyrinth structure. The utility model is used for preventing the oil shield of the water supply pump from leaking.
Description
Technical Field
The utility model relates to an oil shield leakage-proof structure of a water supply pump.
Background
The raw oil gear of the water supply pump HPT300-340-6S is in a structure form of three dynamic and static combinations, the dynamic ring is driven to rotate by the extrusion force generated by the O-shaped ring between the dynamic ring and the shaft, the internal mechanism is complex, the oil sludge is generated in the internal mechanism by long-time operation, the friction force between the dynamic ring and the static ring is increased, and the dynamic ring and the shaft generate relative motion.
Disclosure of Invention
The utility model aims to provide a water pump oil shield leakage-proof structure for solving the problems in the background technology.
The above object is achieved by the following scheme:
the utility model provides a water pump oil shield leak protection structure which constitutes and includes: the oil splash device comprises a bearing body and a shaft, wherein an oil baffle is arranged in the bearing body, the shaft and an oil splash ring are fixed through jackscrews, and teeth of an inner ring of the oil baffle and teeth of an outer ring of the oil splash ring are distributed in a staggered mode to form a labyrinth structure.
The water pump oil shield leak-proof structure is characterized in that the oil shield is provided with an oil drain hole.
The water pump oil shield leakage prevention structure is characterized in that an O-shaped ring is fixed between the shaft and the oil splashing ring.
Advantageous effects
1. The oil baffle and the splash ring are staggered with each other to form the labyrinth structure, so that lubricating oil in the bearing body is sealed, oil leakage at the oil baffle part can be effectively prevented, and residual oil in the labyrinth structure is effectively discharged through the oil leakage hole by relative rotation of the oil baffle and the splash ring, so that the oil is prevented from leaking from a gap between the oil baffle and the splash ring.
2. The utility model is provided with the radial O-shaped ring to thoroughly seal a plurality of radial gaps between the oil splashing ring and the shaft, thereby avoiding oil leakage from the gaps.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: 1. an oil shield; 2. a jackscrew; 3. an O-ring; 4. oil splashing rings; 5. an oil drain hole; 6. a bearing body; 7. a shaft.
Detailed Description
Referring to fig. 1, a water pump oil shield leakage prevention structure comprises: the oil splash device comprises a bearing body 6 and a shaft 7, wherein an oil baffle 1 is arranged in the bearing body, the shaft and an oil splash ring 4 are fixed through jackscrews 2, and teeth of an inner ring of the oil baffle and teeth of an outer ring of the oil splash ring are distributed in a staggered mode to form a labyrinth structure.
The oil baffle is provided with an oil drain hole 5.
An O-shaped ring 3 is fixed between the shaft and the splash oil ring.
The oil baffle is a static piece and is arranged in the bearing body; the splash ring 4 is a rotating piece and is fixed with the shaft 7 through the jackscrew 2 so as to realize synchronous rotation with the shaft;
the oil baffle 1 and the splash oil ring 4 are staggered with each other to form a labyrinth structure, so that lubricating oil in the bearing body is sealed; the structure can effectively prevent the oil leakage phenomenon of the oil baffle part, effectively discharge the residual oil in the labyrinth structure through the oil leakage hole through the relative rotation of the oil baffle and the splash ring, and prevent the oil from leaking out from the gap between the oil baffle and the splash ring.
Radial O-shaped rings are additionally arranged: the radial gaps between the oil splashing ring and the shaft are thoroughly sealed, and oil leakage from the gaps is avoided.
Three uniformly distributed jackscrews are added: the splash ring is tightly connected with the shaft, so that the splash ring is relatively static, the relative friction between the splash ring and the shaft is avoided, the service life is prolonged, and the maintenance cost is saved.
And an axial oil drain hole is additionally arranged: the structure can effectively discharge the oil remained in the oil return groove, and prevent the oil from leaking from the gap between the oil baffle and the splash oil ring.
Claims (3)
1. The utility model provides a water pump oil shield leak protection structure which constitutes and includes: bearing body and axle, characterized by: the bearing body is internally provided with an oil baffle, the shaft and the splash ring are fixed through jackscrews, and the inner ring of the oil baffle and the teeth of the outer ring of the splash ring are distributed in a staggered manner to form a labyrinth structure.
2. The water pump oil shield leakage prevention structure according to claim 1, characterized in that: the oil baffle is provided with an oil drain hole.
3. The water pump oil shield leakage prevention structure according to claim 2, characterized in that: an O-shaped ring is fixed between the shaft and the splash oil ring.
