Embodiment 1

[0018] The motor damping vibration reduction structure of the present invention, including motor bearing 3, end cover 1, and damping ring 2. Among them, a loop groove 1-1 corresponding to the outer ring with the outer ring of the motor bearing 3 on the end cover 1 isThe section depth of the circular groove 1-1 is 2mm larger than that of the motor bearing 3 in the outer ring, and the cross-section width is set to 5mm.The damping ring 2 is installed in the ring groove 1-1 and adopts a proficiency.The damping ring 2 uses fluorine rubber parts, and its loss factor is 0.11. After comparison testing, the motor is made by the motor of the existing technology. The vibration acceleration level of the motor is 105DB.The acceleration test results are 100dB, which reduces 5DB.

Embodiment 2

[0020] The motor damping vibration reduction structure of this embodiment is basically the same as the embodiment 1. The difference is that the section depth of the ring groove 1-1 is 5mm larger than the outer width of the motor bearing 3, and the section width is 10mm;The mixture of silicon oil and metal particles is installed in the plastic pipe fittings that are adapted to the ring groove 1-1. The weight ratio of the silicon oil and metal particles in the mixture products is 1: 0.3. Among them, the metal particles are lead leadersThree kinds of mixed pills of pills, steel pills and aluminum pills. The mixing pills are based on the weight ratio: Lead Pill: Steel Pill: Aluminum Pill = 1: 1, the particle size of metal particles is 0.4 mm, silicone oilSelect the viscosity to 5000mm 2 / s (25 ° C) methyl silicon oil, the loss factor of 0.15.After comparison testing, the motor is made by the motor of the existing technology. The vibration acceleration level of the motor is 105 dB. Acc...

Abstract

The invention relates to a motor damping vibration attenuation structure. The motor damping vibration attenuation structure is mainly characterized in that an annular groove is formed in the outer side of a motor end cover bearing chamber, and a damping ring is installed in the groove. By means of the motor damping vibration attenuation structure, a fluororubber damping ring or a silicone oil damping ring is installed in the annular groove of the outer side of an upper bearing chamber of a bearing end cover, vibration of a motor can be effectively reduced, and the vibration acceleration grade of the motor can be reduced by 4-12dB after the damping ring is installed after a comparison test. The motor damping vibration attenuation structure is simple and compact and easy to machine, the damping ring can be installed conveniently, and general utilization of the motor end cover can be conducted easily.

Description

Technical field [0001] The present invention belongs to the field of motor technology, especially a motor damping vibration reduction structure. Background technique [0002] In the processing and production of the motor, the motor is inevitably vibrated during the operation of design and manufacturing.In addition, the motor vibration not only has electromagnetic vibration, but also various mechanical vibrations. Traditional technologies usually use increased material dosage, that is, the method of lengting iron core and increasing stator winding wires to achieve vibration reduction.However, the vibration brought by the manufacturing error and the system resonance caused by a certain band.Moreover, this motor vibration reduction method makes the motor a larger volume, and its weight is much larger than the motor of the same specifications. Although it can achieve a certain vibration reduction effect, it increases the manufacturing cost of the motor to a large extent.Moreover, the...
