Background technique
The design of low vibration motor, which is generally started in terms of reducing motor energization source and optimization transmission path two, carries out the work. For example weaken electro-magnetic exciting force by selecting the measures such as the cooperation of suitable pole slot, stator or rotor chute, biggish air gap, To reduce the vibration of motor;Transmission path optimization increases damping generally by optimization transmission path to reduce exciting force to electricity The transmitting of machine mounting surface.
Vertical machine driving source transmission path is different from horizontal machine, and the vibration of rotor is transferred directly to by bearing Lower cover, few to the optimization method of transmission path, vibration damping work is more difficult.
Summary of the invention
It is an object of the invention to deficiencies according to prior art, design a kind of low vibration vertical machine, this low vibration is vertical Formula motor optimizes field waveform using reasonable pole slot cooperation+skewed slot+bias air gap, weakens electro-magnetic exciting force, subtracts from source The vertical motor axial vibration of the immersion needle of small machine;High-damping cupromanganese lower cover is used simultaneously, and bearing fixing end is put It is placed in lower cover, inhibits rotor axial direction displacement, to reduce the vibration of motor.
The technical solution adopted by the present invention to solve the technical problems is: a kind of low vibration vertical machine, including it is hollow on The cylindric base and heat of lower both ends open are set on the stator on inboard wall of base, the upper and lower side opening of the base It is fixedly installed upper end cover and lower cover respectively, is also movably set in the inner cavity of the base and turns with what stator was used cooperatively Son, the upper and lower side and upper end cover of the rotor and the junction of lower cover are respectively arranged with upper bearing (metal) and lower bearing, described The inner ring of upper bearing (metal) is connected with the cooperation of the upper end hot jacket of rotor, and the outer ring of the upper bearing (metal) is connected with upper end cover transition fit It connects, the upper capping being fixedly installed on the upper end cover above upper bearing (metal), between the upper bearing (metal) and upper capping also It is provided with cushion blocking;The inner ring of the lower bearing is connected with the cooperation of the lower end hot jacket of rotor, the outer ring of the lower bearing It is fixed on lower cover;The pole slot cooperation of the low vibration vertical machine uses 16 pole, 96 slot, using oblique 1 times of stator Stator slot is away from eccentricity rate is 0.64.
The lower cover is fixed on base by the first bolt, and the outer ring of the lower bearing passes through the second spiral shell Bolt is fixed on lower cover.
The lower cover is high-damping cupromanganese part.
The beneficial effects of the present invention are: the rotor number of poles of the low vibration vertical motor rotor of disclosure of the invention is 16, stator Number of stator slots is 96 slots, and oblique 1 times of the stator slot of stator is away from, eccentricity of rotor/rotor diameter=0.64, the field waveform after optimization Effectively lower electro-magnetic exciting force, weakens magnitude of vibrations;The lower bearing fixing end of this low vibration vertical machine is arranged on lower cover, It can inhibit the axial displacement and vibration of rotor;Lower cover uses high-damping cupromanganese, can further filter absorption of from rotor Axial vibration, reduce motor overall vibration index.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Each appended drawing reference are as follows: 1-base, 2-stators, 3-lower covers, 4-lower bearings, 5-rotors, the 6-the first bolt, 7-the second bolt, 8-upper end covers, 9-upper bearing (metal)s, 10-upper cappings, 11-cushion blockings.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Shown in referring to Fig.1, the invention discloses a kind of low vibration vertical machine, the cylinder including hollow upper and lower ends opening Shape base 1 and heat are set on the stator 2 on 1 inner wall of base, and the upper and lower side opening of the base 1 is fixedly installed respectively There are upper end cover 8 and lower cover 3, the rotor 5 being used cooperatively with stator 2 is also movably set in the inner cavity of the base 1, it is described The upper and lower side of rotor 5 and the junction of upper end cover 8 and lower cover 3 be respectively arranged with upper bearing (metal) 9 and lower bearing 4, wherein lower end Lid 3 is fixed on base 1 by the first bolt 6, and the outer ring of lower bearing 4 is fixed at lower cover 3 by the second bolt 7 On, the inner ring of the upper bearing (metal) 9 is connected with the cooperation of the upper end hot jacket of rotor 5, the outer ring of the upper bearing (metal) 9 and upper end cover 8 transition fits are connected, the upper capping 10 being fixedly installed above upper bearing (metal) 9 on the upper end cover 8, the upper axis It holds and is additionally provided with cushion blocking 11 between 9 and upper capping 10;The inner ring of the lower bearing 4 and the lower end hot jacket of rotor 5 cooperate phase Connection, the outer ring of the lower bearing 4 is fixed on lower cover 3;The pole slot cooperation of the low vibration vertical machine is adopted With 16 pole, 96 slot, using oblique 1 times of the stator slot of stator away from eccentricity rate is 0.64.The vertical electricity of low vibration disclosed by the invention The axial vibration of rotor 5 directly passes through lower bearing 4 and is transmitted on lower cover 3 machine in the process of running, lower bearing 4 and lower cover 3 For rigid connection, without relative displacement, lower cover 3 is rigidly secured on base 1, and vibration values are smaller at base 1.And bearing is consolidated Fixed end is set to the existing vertical machine of top end cover, and bottom bearing and bottom head covers have relative displacement when motor operation, increases Motor oscillating is added, base position vibration values are larger.
