[background technology]

At present; The common on the market various household electrical appliances that need to drive wind-force, like the motor that the axial-flow leaf that air-conditioning, refrigerator, water heater, exhaust blower adopted is used, the rotating shaft two ends of its rotor are to adopt ball bearing to support running mostly; Because this bearing self friction resistance and misalignment; Produce noise through regular meeting during running, and production cost is high, therefore can't satisfy the demand of people to low noise, energy-conservation aspect.

The utility model has carried out useful improvement in order to overcome above shortcoming.

[utility model content]

The utility model is to prior art, provide a kind of simple in structure, purposes is wide, noise is low, efficient is high, energy-conservation, cost is low, frictional resistance is little no bearing New-type electric machine.

The purpose of the utility model is achieved in that

A kind of no bearing New-type electric machine; Comprise motor housing, be arranged in the motor housing and cooperatively interact stator and rotor; Rotor is provided with rotation axis; On motor housing, be provided with axis hole, an end of the rotation axis of said rotor can pass axis hole and expose outside the motor housing, it is characterized in that the rotation axis two ends in motor housing are respectively equipped with the Sliding bush assembly that can support the rotation axis running; The Sliding bush assembly comprises the fixed cap that is fixed on the motor housing; In fixed cap, on the axis hole of motor housing, be provided with rotatable bearing shell, between bearing shell and fixed cap, be provided with and can bearing shell be pressed on the elasticity gland on the axis hole, an end of said rotation axis passes fixed cap, elasticity gland, bearing shell, axis hole successively and exposes outside the motor housing.

Aforesaid a kind of no bearing New-type electric machine; It is characterized in that motor housing comprises motor housing, following motor housing; On last motor housing and following motor housing, be respectively equipped with axis hole; Be provided with the recess that is complementary with bearing shell and grab that can fixed cap is fixing at the axis hole periphery, the bottom outer wall of said fixed cap is stuck in the grab and through the elasticity gland bearing shell is pressed in the recess.

Aforesaid a kind of no bearing New-type electric machine is characterized in that said bearing shell for spherical, is provided with the location hole that is complementary with bearing shell on the elasticity gland, and said elasticity gland is pressed on the bearing shell through location hole.

Aforesaid a kind of no bearing New-type electric machine is characterized in that described bearing shell, elasticity gland, fixed cap processed by pottery or metal or plastics.

The utility model compared with prior art has following advantage: because the rotation axis two ends in motor housing are respectively equipped with the Sliding bush assembly that can support the rotation axis running; The bearing shell of Sliding bush assembly is in suspended state and can rotates with rotation axis when rotation axis rotates, rotation axis can't be beated, and locatees more accurate; Resistance is littler during operation, noise is lower; Efficient is higher, the life-span is longer, and is more energy-conservation, and the utility model volume is little; Can be widely used in the household appliances of various small-sized drivings, like air-conditioning, refrigerator, water heater, exhaust blower.
