Abstract

The utility model provides an integrated motor rear end cover, which is an integral structural element having the structure characteristics of general motor rear end cover and brush basin; wherein theinner surface of the rear end cover is provided with a plurality of fixtures for mounting electrical components and an outlet clip for fixing lead out wires, the center of the end cover is provided with a bearing hole, and a bearing chamber is provided at the periphery of the bearing hole, for arranging an oil bearing. The integrated motor rear end cover has low weight, easy formation and reducedmaterial consumption. The motor adopting the rear end cover can avoid brush basin, bearing gland, asphalt felt, brush holder, inductance holder and the like, and has short axial short, effective heatdissipation and high reliability.

Description

A kind of integrated motor rear end cover

Technical field

The utility model relates to a kind of motor, relates in particular to a kind of integrated motor rear end cover.

Background technology

Motor rear end part generally is provided with rear end cap, brush basin, bearing gland and asphalt felt.Rear end cap generally adopts metal material to make, and installs separately, and the brush basin generally adopts plastics and/or metal material to make, and installs separately separately.Bearing gland need link to each other with the rear end cap riveted joint.When making, need die sinking moulding respectively; When mounted, need again to install respectively, waste time and energy, the cost height; And taken more motor axial dimension and space, hinder miniaturization, the thin typeization of motor.In addition, because the rear end cap of making generally adopts metal material to make separately, weight is heavier, has both consumed metal material, has increased the weight of the weight of motor again.

The utility model content

The purpose of this utility model exactly in order to address the above problem, provides a kind of integrated motor rear end cover with new structure.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of integrated motor rear end cover, it is a integral structure component with back end cover for motor architectural feature commonly used and brush basin architectural feature, its medial surface is provided with a plurality of fixtures that are used to install each electric elements, and the terminal clamp that is used for fixing lead-out wire, center at end cap is provided with dead eye, is characterized in: also be provided with the bearing chamber that is used to install oiliness bearing around described dead eye.

Described bearing chamber comprises the first half that stretches out the inboard of end cap backward and the outside of end cap the latter half of stretching out backward, the first half and the latter half and each are made of four baffle plates that are disposed in an evenly spaced relation on the same circumference, and the baffle plate of formation the first half is staggered with the baffle plate that constitutes the latter half and interconnects; The medial surface that constitutes four baffle plates of the first half is linked to be a spherical cambered surface at interval; The medial surface that constitutes four baffle plates of the latter half is linked to be a spherical cambered surface at interval.

Described terminal clamp is the plug-in type terminal clamp.

The utility model integrated motor rear end cover makes it compared with prior art owing to adopted above technical scheme, have following advantage and and characteristics:

1, the utility model integrated motor rear end cover structure is new, part is few,---adopt the motor of this rear end cap can save brush basin, bearing gland, asphalt felt, brush carrier, inductance frame etc.

2, low, in light weight, the material province of the utility model integrated motor rear end cover cost---both economize copper, economized steel again, thereby saved the resource of national precious.

3, the utility model integrated motor rear end cover has not only guaranteed the function of use of traditional structure, and axial dimension is short, heat radiation is more favourable, and reliability is higher.

4, the utility model integrated motor rear end cover has reduced the processing technology of traditional structure rear end cap assembling---and do not need the riveting of bearing gland and rear end cap to restrain, do not need asphalt felt

5, the utility model integrated motor rear end cover applicability is wide, can promote the use of the fan electromotor of all size power, can supportingly be used for high, medium and low shelves automobile, car, especially economical, compact car are more suitable for being used for car narrow and small between engine air.
