Abstract
The utility model relates to a cover plate of a shaft hole of an engine, which comprises a flange edge. The utility model is characterized in that the external lateral surface is connected with the flange edge, the flange edge is provided with fixing holes, the internal lateral surface is provided with a positioning lug boss, and the external lateral surface is a cambered surface. After the utility model is adopted, the cambered surface structure of the external lateral surface can absorb noise and reduce resonance. Consequently, the noise of an engine can be effectively reduced. Moreover, the utility model is one-step molded in an extrusion mode by adopting engineering plastics. The utility model has the advantages of low cost, and beautiful appearance.
Description
The utility model relates to the axis hole cover plate of the component of motor, particularly motor.
The axis hole cover plate of available engine, contain flange edge, outer side surface links to each other with flange edge, flange edge is provided with fixed hole, inside and outside side reaches and the junction plane of engine body side is the plane, and inner side surface is provided with positioning boss, and the axis hole on positioning boss and the engine body matches, positioning boss is provided with pit, and the bottom surface of pit is the plane.Because this structure directly reflects the noise in the body, so noise is big, and to the requirement on machining accuracy height on plane, easily oil impregnate.
The purpose of this utility model is to provide a kind of engine shaft blind patch that can reduce engine noise.
Solution of the present utility model: contain flange edge, outer side surface links to each other with flange edge, and flange edge is provided with fixed hole, and inner side surface is provided with positioning boss, and outer side surface is a cambered surface.
Material is engineering plastics.
After adopting the utility model, the globoidal structure of outer side surface can produce diffuse reflection to noise, reduces resonance, can reduce the noise of motor effectively.Adopt an extrusion modling of engineering plastics, cost is low, beautiful shape.
Accompanying drawing has provided 2 embodiments of the present utility model.
Embodiment 1:
Fig. 1 is the utility model embodiment 1 an outer side surface structural representation;
Fig. 2 is the utility model embodiment 1 a sectional view;
Fig. 3 is the utility model embodiment 1 an inner side surface structural representation.
Below in conjunction with accompanying drawing embodiment 1 of the present utility model is described in detail: contain flange edge 9, outer side surface 1 links to each other with flange edge 9, be arranged with 3 fixed holes 7 on the flange edge 9, outer side surface 1 is a cambered surface, inner side surface is provided with positioning boss 10, and positioning boss 10 is provided with pit 8, and the bottom surface of pit 8 is a cambered surface, cambered surface is provided with the grid structure 2 of band convex tendon 3, and the periphery of fixed hole 7 and positioning boss 10 is respectively equipped with seal boss 11; Adopt the engineering plastics extrusion moulding.
Embodiment 2:
Fig. 4 is the utility model embodiment 2 an outer side surface structural representation;
Fig. 5 is the utility model embodiment 2 a sectional view;
Fig. 6 is the utility model embodiment 1 an inner side surface structural representation.
Below in conjunction with accompanying drawing embodiment 2 of the present utility model is described in detail: contain flange edge 9, outer side surface 1 links to each other with flange edge 9, be arranged with 2 fixed holes 7 on the flange edge 9, outer side surface 1 is a cambered surface, inner side surface is provided with pit 8, the bottom surface of pit 8 is a cambered surface, and cambered surface is provided with the grid structure 2 of band convex tendon 3, and the periphery of fixed hole 7 and pit 8 is respectively equipped with seal boss 4,5,6; Adopt the engineering plastics extrusion moulding.
