The utility model provides a high temperature resistant motor, which belongs to the technical field of motor. The high temperature resistant motor includes an outer barrel and an inner barrel which is arranged in the outer barrel and has the heat preservation effect. The inner barrel is fixedly provided with a motor body which includes a rotating shaft. The front end of the inner barrel and the outer barrel is provided with a through hole which is opposite to the rotating shaft. The front end of the rotating shaft passes through two through holes and is outside the outer barrel. The rear end of the rotating shaft is fixed with a leaf, the rear end of the inner barrel extends out of the outer barrel, and the rear end and the outer wall of the inner barrel are integrally formed with a retaining ring, The outer diameter of the retaining ring is larger than the outer diameter of the outer barrel. An exhaust passage is formed between the front end face of the retaining ring and the rear end face of the outer barrel. A connecting rod is arranged in the exhaust passage. The length of the connecting rod extends along the axial direction of the inner barrel. Both ends of the connecting rod are fixedly connected with the outer barrel and the retaining ring. At least two connecting rods are distributed along the circumference of the outer barrel. A bearing is arranged between the inner barrel and the outer barrel. Both ends of the bearing are in two through holes respectively. The inner ring of the bearing is It is fixedly connected with the shaft, and the inner barrel and the outer barrel are fixedly connected with the outer ring of the bearing. The high temperature resistant motor works stably.
【技术实现步骤摘要】
一种耐高温电机
本技术属于电机领域,涉及一种电机,特别是一种耐高温电机。
技术介绍
高温排烟风机是一种用于排出高温烟气的通风机,其所配套的电机必须采用具备耐高温性能的电机。现有的耐高温电机如中国专利库公开的一种电机【申请号:201821293511.7】包括护桶以及均设于护桶内的电机本体和散热风叶,所述的电机本体包括转轴,转轴的前端伸出护桶,且转轴的后端与散热风叶固连,所述的护桶内还设有由保温材料制成的隔热桶,隔热桶和护桶均呈圆桶状,且隔热桶和护桶两者的中心轴线共线,所述的电机本体固定在隔热桶内,所述的隔热桶的桶口朝后设置,且隔热桶的前端具有供转轴穿过的连接孔,所述的隔热桶的外径小于护桶的内径,转轴外套有连接环,且连接环通过轴承与转轴可转动相连,连接环位于护桶和隔热桶之间,且连接环的前后两端分别与护桶和隔热桶相固连。上述的电机存在一个问题:护桶和隔热桶之间的间隙沿护桶的轴向向外散热,导致在散热风叶的吸引下,部分热气会回流到内桶内部,影响电机散热,从而影响电机寿命和工作稳定性。
