The invention belongs to the technical field of electromagnetic eddy current brakes, and relates to an air-cooled electromagnetic eddy current brake device. Stators are fixedly connected to the two sides of the inner wall of a shell, coils are fixedly connected to the surfaces of the stators, a double-row centripetal spherical ball bearing is fixedly connected to the interior of the shell through a connecting plate, and a rotor shaft is arranged in the double-row centripetal spherical ball bearing in a penetrating mode; and a rotor is fixedly connected to the other side of the rotor shaft, an air gap is formed between the rotor and the stators, a respirator is fixedly connected to the top of the shell, and grease fittings are fixedly connected to the two sides of the shell. According to the air-cooled electromagnetic eddy current brake device, grease is injected into the double-row centripetal spherical ball bearing through the grease fittings before brake work, so that the double-row centripetal spherical ball bearing can be lubricated, and meanwhile, lubricating grease can be injected into the bearing when the brake is not used, so that the rotor is prevented from being adhered to the surfaces of the stators due to dust accumulation, corrosion and the like.
本发明属于电磁涡流刹车技术领域,涉及一种风冷电磁涡流刹车装置,外壳内壁的两侧均固定连接有定子,定子的表面固定连接有线圈,外壳内通过连接板固定连接有双列向心球面滚珠轴承,双列向心球面滚珠轴承内穿设有转子轴,转子轴的另一侧固定连接有转子,转子与定子之间开设有空气隙,外壳的顶部固定连接有呼吸器,外壳的两侧固定连接有黄油嘴,该风冷电磁涡流刹车装置通过黄油嘴在刹车工作前将黄油注入到双列向心球面滚珠轴承内,从而可对双列向心球面滚珠轴承进行润滑,同时可也在刹车不使用的时候将润滑脂注入到轴承内,避免转子因积尘锈蚀等原因粘贴在定子表面。
