Abstract
The utility model relates to a kind of shaft end nut for axle head, comprise shaft end nut, it is characterized in that: described shaft end nut is hemisphere, and counterbore is offered in the centre of its planar base, the inwall of counterbore offers screw thread, hemispherical avris offers two tangent planes.Two tangent planes are parallel to each other, and two tangent planes are symmetrical with the axle center of shaft end nut.Advantage of the present utility model: can play guide functions well, reduces the hydraulic loss of water pump.
Description
Technical field
The utility model relates to a kind of nut, especially for the shaft end nut of axle head.
Background technique
At the pump shaft end at water pump vane place, shaft end nut is needed pump shaft and water pump vane to be locked, the plain nut that what nut used at present generally adopted is at ordinary times, but when being connected on axle head because plain nut is stubborn, its hexagonal structure can have a negative impact to the current of water pump, has hydraulic loss.Therefore need to improve the structure of shaft end nut, to reduce the hydraulic loss of water pump.
Model utility content
The utility model object solves in prior art to carry out with plain nut the hydraulic loss problem that pump shaft and water pump vane be locked existing, provides a kind of shaft end nut for axle head.To achieve these goals, the utility model is achieved in that a kind of shaft end nut for axle head, comprise shaft end nut, it is characterized in that: described shaft end nut is hemisphere, counterbore is offered in the centre of its planar base, the inwall of counterbore offers screw thread, hemispherical avris offers two tangent planes.Two tangent planes are parallel to each other, and two tangent planes are symmetrical with the axle center of shaft end nut.Advantage of the present utility model: can play guide functions well, reduces the hydraulic loss of water pump.
Accompanying drawing explanation
Accompanying drawing 1 is the structural profile schematic diagram of prior art, and Fig. 2 is the plan view of Fig. 1.
Accompanying drawing 3 is structural profile schematic diagram of the present utility model, and Fig. 4 is the plan view of Fig. 3.
Embodiment
For a shaft end nut for axle head, comprise shaft end nut 1, it is characterized in that: described shaft end nut is hemisphere, counterbore 2 is offered in the centre of its planar base, the inwall of counterbore offers screw thread 4, and hemispherical avris offers two tangent planes 4.Two tangent planes are parallel to each other, and two tangent planes are symmetrical with the axle center of shaft end nut.
Be processed as hemisphere by outside shaft end nut, then on sphere, process the operation of two parallel surfaces for spanner.When pump working, its hemispheric structure can play guide functions well, reduces the hydraulic loss of water pump.
