Description

[Technical Field]

[0001] This utility model relates to the field of electric motor technology, specifically to an anti-vibration electric motor for a forging hammer machine tool. [Background Technology]

[0002] Forging hammer machine tools experience significant vibrations, subjecting the electric motors used in them to substantial impacts and vibrations. This inevitably affects the motors' performance and lifespan. Currently, the anti-vibration motors used in forging hammer machine tools suffer from the following main structural shortcomings:

[0003] (1) The bearing structure currently in use is a deep groove ball bearing at the shaft extension end and an angular contact ball bearing at the non-shaft extension end. Its vibration resistance and impact resistance are not as good as those of the self-aligning roller bearing, and it does not have a round nut and locking washer installed, resulting in poor reliability.

[0004] (2) The front cover and housing of the existing structure are connected by baffles and ring keys, which makes installation and disassembly difficult and lacks radial positioning, which will cause radial movement;

[0005] (3) The axial positioning of the existing electric motor fan is achieved by the shaft retaining ring. The shaft retaining ring is thin and has poor rigidity, making it difficult to withstand the vibration and impact of the forging hammer machine tool, which causes the fan to break.

[0006] (4) The steel plate of the existing motor fan cover is relatively thin, and it is easy to break under high frequency vibration and impact;

[0007] (5) The inner and outer covers of the existing motors are too thin and cannot withstand high-frequency impacts;

[0008] (6) The existing motor junction box support space is small. Under high frequency vibration, the cable is easy to rub against the box wall, which can cause a short circuit and result in poor reliability.

[0009] Therefore, reducing the loosening of various components of the motor during vibration and improving the overall vibration resistance and reliability are essential and necessary. [Utility Model Content]

[0010] The purpose of this invention is to address the aforementioned shortcomings by providing an anti-vibration motor for forging hammer machine tools. This motor improves the overall vibration resistance and impact resistance of the motor, reduces the loosening of various components during vibration, has a long service life, and is low in cost.

The stop shoulder is connected with the stop groove, and the front cover 7 is installed on the ring 6 through the stop shoulder and the stop groove, which makes the installation and positioning of the front cover 7 more convenient.

[0014] Furthermore, a fan 10 is provided on the right side of the housing 5. The fan 10 is fixed to the non-shaft extension end of the shaft 15 by a sleeve 8 and a bolt 9, thus providing good vibration resistance and impact resistance.

[0015] Furthermore, the fan 10 is provided with a reinforced fan cover 11, which is connected to the right end of the housing 5. A flange 16 is provided on the reinforced fan cover 11, which is connected to the housing 5 by welding, thereby increasing rigidity and improving stability.
