Explosion-proof motor base adopting ejection line structure

Abstract

The invention discloses an explosion-proof motor base adopting an ejection line structure. The explosion-proof motor base comprises a main junction box base, an auxiliary junction box base and coolingfins. A plurality of ventilating ducts are distributed in the base and arranged in a certain mode; and the connecting positions of the ventilating ducts and a base barrel adopt a variable-thickness structure. Under the premise of not increasing the weight and the center height of the base and ensuring the structural strength of the motor, the radial rigidity of the base structure is improved by adopting a special technical means so as to achieve a shockproof purpose; and meanwhile, the internal ventilation sectional area of the base is increased by adopting a special structural design so as to greatly and effectively improve the internal and external heat exchange efficiency of the base, effectively prolong the service life of the motor and guarantee the operation safety.

Description

technical field [0001] The invention relates to the technical field of motors and is suitable for high-speed, large-capacity explosion-proof motors. Background technique [0002] The current motor industry is developing in the direction of high speed and large capacity, which puts forward higher requirements for the vibration, ventilation and heat dissipation of the frame structure. For explosion-proof motors, in addition to vibration and ventilation and heat dissipation, there are also very high requirements in terms of structural strength. As the most important structural component of the motor, the main part that reduces vibration and noise and improves ventilation and heat dissipation efficiency, the frame The design of the motor is also an important part of the whole motor structure design. [0003] The explosion-proof base has the structure of inner and outer cooling fins and inner air duct. The main excitation source that causes the motor to vibrate is the unbalance...

Problems solved by technology

[0004] The machine base in the prior art vibrates violently, how to prevent large-scale vibration is a technical problem in this field

At the same time, the temperature rises greatly during and after use, which seriously affects the service life and working efficiency of the motor.

In the prior art, for example, the patent documents with the announcement numbers CN209217886U and CN209104929U have made improvements to heat dissipation. However, it is still a prominent problem to thoroughly improve the base itself to enhance its anti-vibration and heat dissipation functions.
