At present on motor installation foot or mounting surface place resilient cushion carry out shock-dampening method not yet can fully effective isolation rotor
Rotational vibrations noise.
Utility model content
The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide a kind of damping dress of motor
It sets, the vibration of motor is effectively reduced.
Purpose of the utility model is realized as follows:
A kind of damping device of motor, the rotor being rotatablely connected including motor casing and in it, which is characterized in that the electricity
The both ends of casing respective rotor axial direction are respectively equipped with bearing chamber, and two bearings outside is respectively equipped with motor casing shock absorbing ring.
The both ends of the motor casing respective rotor axial direction are respectively formed the assembled end of motor casing, two bearings room difference
It outwardly protrudes in the assembled end at motor casing both ends, motor casing shock absorbing ring is set in the outside of bearing chamber.
The motor casing shock absorbing ring is set on the outer surface and assembled end of bearing chamber.
The two bearings chamber interior is respectively arranged with the bearing with rotor rotation connection.
Rotor shock absorbing ring is respectively equipped on the inside of the two bearings room, rotor shock absorbing ring makes bearing and the bearing chamber where it
Isolation.
The rotor shock absorbing ring is set on the inner wall and inner bottom surface of bearing chamber.
The motor casing is closed by drive end bearing bracket and rear end cap lid.
The utility model beneficial effect is:
By the way that the technical solution of motor casing shock absorbing ring is arranged on the outside of bearing chamber, motor when can be effectively reduced motor work
The vibration generated between installation casing reduces resonance noise.
Also by the way that the technical solution of rotor shock absorbing ring is arranged on the inside of bearing chamber, it is effectively reduced, rotor is isolated in height
Produced radial and axial vibration, reduces the transmitting noise of rotor in speed rotation.
The utility model is simple and reasonable, safe and reliable, can be suitable for various fields use, as electric fan,
Air-conditioning aerofoil fan, smoke machine aerofoil fan etc..
Detailed description of the invention
Fig. 1-Fig. 2 is the cross-sectional view of the utility model first embodiment motor casing shock absorbing ring.
Fig. 3 is the cross-sectional view of the utility model first embodiment rotor shock absorbing ring and motor casing assembly.
Fig. 4 is the cross-sectional view of the total assembling structure of the utility model first embodiment.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
First embodiment
Referring to figures 1-4, the damping device of this motor, the rotor 5 being rotatablely connected including motor casing and in it, the electricity
The both ends of 5 axial direction of casing respective rotor are respectively equipped with bearing chamber, and two bearings outside is respectively equipped with motor casing shock absorbing ring 4.
Motor casing shock absorbing ring 4 can absorb generated vibration when motor work, to reduce resonance noise.
Further, the both ends of 5 axial direction of motor casing respective rotor are respectively formed the assembled end 11 of motor casing,
Two bearings room outwardly protrudes the assembled end 11 in motor casing both ends respectively, convenient for forming the radially loading of shock absorption ring of motor 4 with fixed
Position, motor casing shock absorbing ring 4 are set in the outside of bearing chamber, guarantee that their concentricity and motor casing shock absorbing ring 4 are attached to axis
Hold the lateral stabilization degree of room.
Further, the motor casing shock absorbing ring 4 is set on the outer surface and assembled end 11 of bearing chamber, is met
The matching requirements of all kinds of installation casings.
When motor and installation casing are assembled, the two is isolated by motor casing shock absorbing ring 4, and the vibration that motor generates when working will
It is absorbed, will not be directly delivered on cabinet by motor casing shock absorbing ring 4, to reduce resonance noise.
Further, the two bearings chamber interior is respectively arranged with the bearing 51 being rotatablely connected with rotor 5, guarantees rotor 5
The axial stability of rotation.
Further, be respectively equipped with rotor shock absorbing ring 3 on the inside of the two bearings room, rotor shock absorbing ring 3 make bearing 51 with
Bearing chamber isolation where it is effectively reduced, rotor produced radial and axial vibration in high-speed rotation is isolated, subtracts
Transmitting noise from small motor rotor to motor casing, to realize dual shock absorption effect.
Further, the rotor shock absorbing ring 3 is set on the inner wall and inner bottom surface of bearing chamber, can be enveloped completely
The contact surface of bearing 51 and bearing chamber where it, shock-absorbing effect is good, and can guarantee with the build-up tolerance of bearing chamber reasonable
In range, guarantee the concentricity of motor casing, rotor 5, assembled end 11 and bearing 51.
In the present embodiment, the motor casing is closed by drive end bearing bracket 1 and the lid of rear end cap 2, those skilled in the art
Understand.
Rotor shock absorbing ring 3 is first respectively arranged in drive end bearing bracket 1 with after in the production assembling process of motor by the utility model
In the bearing chamber of end cap 2；After drive end bearing bracket 1 assembles stator, the rotor that the bearing 51 positioned at 5 front side of rotor is inserted into drive end bearing bracket 1 subtracts
In the inner ring of shake circle 3, then the rear end cap 2 for having installed rotor shock absorbing ring 3 and drive end bearing bracket 1 are assembled together, this assembly
Structure is simple, safe and efficient, convenient and reliable.
Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability
