Abstract

A shock-absorbing type micro motor mainly comprises a rotor and a stator, wherein, the rotor comprises a rotating shaft, and the stator comprises an output end cover and an input end cover which are respectively fixed on a first bearing and a second bearing; and the first bearing and the second bearing are mounted on the rotating shaft. The shock-absorbing type micro motor is characterized by further comprising a first vibration reduction ring and a second vibration reduction ring; and the first vibration reduction ring is fixed between the output end cover and the first bearing, and the second vibration reduction ring is fixed between the input end cover and the second bearing. The shock-absorbing type micro motor has the benefits that the vibration reduction rings are respectively and additionally arranged between the output end cover and the first bearing, and between the input end cover and the second bearing, so that the vibration of the end covers can be reduced in practical use, and the motor with major load can prevent the vibration from being transmitted to the end covers through the bearings so as to achieve the purpose of vibration reduction.

Description

A kind of shock-absorbing type micromachine

Background technology

Along with the continuous increase to consumption such as household electrical appliance, electronics that improves constantly of production modernization degree with people, market to the demand of micromachine also with increasing.The employed micromachines of machine for kitchen use such as existing fruit juice mixer, agitator for food-making because of the imbalance of cutter and bearing load, thereby cause the vibration of complete machine work and noise bigger.The structure of existing micromachine mainly comprises rotor and stator two parts, and stator is the stationary part of motor, is mainly used to produce magnetic field, and stator mainly comprises main pole, brushgear, support and end cap; Rotor is the rotating part of motor, and the main effect of rotor is an induced electromotive force, produces electromagnetic torque, makes mechanical energy become the hinge that electric energy (generator) or electric energy become mechanical energy (motor), and it mainly comprises armature, commutator and rotating shaft.In practical work process, because described cutter directly is connected in the rotating shaft, described motor is in driving the rotating shaft rotating process, and described rotating shaft meeting drives cutter work, and the vibration of described cutter can drive the vibration of bearing and end cap successively and conduct to the shell of electrical equipment.In actual use, not only influence the use of household appliances, bring great inconvenience to daily life simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of shock-absorbing type micromachine of good damping result.For achieving the above object, the utility model adopts following structure: a kind of shock-absorbing type micromachine, mainly comprise rotor and stator two parts, described rotor comprises rotating shaft, described stator comprises output lid and input end cap, described output end cap and input cover and are fixed with the clutch shaft bearing and second bearing respectively, the described clutch shaft bearing and second Bearing Installation are in rotating shaft, it is characterized in that: further comprise first damping ring and second damping ring, described first damping ring is fixed between described output end cap and the clutch shaft bearing, between the fixing described input end cap of described second damping ring and second bearing.

Described a kind of shock-absorbing type micromachine is characterized in that: described first damping ring is the metal damping ring, and described second damping ring is the rubber damping circle.

Described first damping ring and second damping ring are the metal damping ring.

Described first damping ring is the rubber damping circle, and described second damping ring is the metal damping ring.

Described input end cap is formed in one, and input covers and has the electronic component installation cavity.

The beneficial effects of the utility model are: between described output end cap and the clutch shaft bearing, increase damping ring respectively between input end cap and second bearing, in actual use, can alleviate the vibration of end cap, make the bigger load of motor carrying can stop vibration, thereby reach the purpose of vibration damping via the conduction of bearing to end cap.
