Vertical type motor
专利汇可以提供Vertical type motor专利检索，专利查询，专利分析的服务。并且PURPOSE: To flow down lubricating oil spontaneously, and to shorten the length of a motor by penetrating the outlet side of a piping for lubricating oil for a bearing on the upper side of the vertical type motor with an oil-air lubrication type roller bearing to the coil end of a stator.
CONSTITUTION: A shaft 4 for a vertical type motor consisting of a stator 1 and a rotor 3 is supported rotatably by a pair of upper and lower oil-air lubrication type roller bearings 8, 9. Lubricating oil is circulated by an inlet pipe 91 and an outlet pipe 92 for lubricating oil in the bearing 9 on the lower side. The bearing 8 on the upper side is lubricated by an inlet pipe 81 and an outlet pipe 82 for lubricating oil, but the outlet pipe 82 is penetrated to the end section of a stator coil 2. Accordingly, the drain of lubricating oil can be flowed down spontaneously while the bearings 8, 9 are arranged inside the stator coil 2, thus shortening the length of the whole motor. The motor is suitable for revolution at high speed of a spindle motor, etc.
