Abstract
Description
本發明有關於一種馬達,尤其一種具有油路循環之馬達。The invention relates to a motor, in particular a motor having an oil circuit circulation.
按,一般馬達之軸承於高速轉動中會產生高溫,而為了解決轉動所產生之高溫問題,通常會在馬達端部設置一隨馬達轉軸轉動的葉扇,透過馬達轉軸於轉動中,葉扇可將外部空氣導入馬達內部,作為空間的循環交換,以降底馬達之軸承工作溫度,惟如此效果並非絕佳,特別是在轉動的過程中,往往發熱的是轉動之相關元件,如此沒有直接對其冷卻,則工作溫度並無法得到實質的降低。According to the general motor bearing, high temperature is generated during high-speed rotation. In order to solve the high temperature problem caused by the rotation, a fan fan rotating with the motor shaft is usually arranged at the end of the motor, and the fan shaft is rotated through the motor shaft.

However, the effect is not excellent, especially in the process of turning, the component that is often heated is the related component of the rotation, so there is no direct When cooled, the operating temperature cannot be substantially reduced.
後來為了解決這樣的問題,有利用冷卻油霧化的方式,直接對馬達內的軸承部位進行冷卻降溫,惟此種方式礙於冷卻油霧化後是一小分子結構,在噴霧的過程中易擴散於工廠,導致空氣品質不佳,以及易使工作人員吸入過量的冷卻油而影響健康,同時如果沒有配合油料的回收,在使用上亦為一種浪費。Later, in order to solve such problems, there is a way to cool down the bearing parts in the motor by means of cooling oil atomization. However, this method is a small molecular structure after the cooling oil is atomized, and is easy to be sprayed. Diffusion in the factory, resulting in poor air quality, and easy to allow workers to ingest excessive cooling oil and affect health, and if not recycled with oil, it is also a waste of use.
為解決上述課題,本發明揭露一種具有油路循環之馬達,係直接將冷卻油循環於馬達之軸承周緣部位,以達冷卻降溫之效果。In order to solve the above problems, the present invention discloses a motor having an oil circuit circulation, which directly circulates cooling oil to a peripheral portion of a bearing of the motor to achieve the effect of cooling and cooling.
