A new seal structure of motor bearing which is a non-contact seal. It includes a motor shaft and a mechanical bearing and it is characterized in that an oil retainer is installed on the left side of mechanical bearing about the terminal of the electric engine's output axis which is fixed by the tacking screw and the motor shaft. At one end and upper of the oil retainer install a hydro-extracting loop which is connected by the sunken screw and the one end of the oil retainer and then install the shaft cap. The characteristic of the invention is that between the hydro-extracting loop, shaft cap and the oil retainer there is a maze structure which has the seal affection. Because the hydro-extracting loop and the oil retainer don't need to treat the maze slot it is convenience to be treated while having good seal affection.
Description
technical field [0001] The invention relates to a motor, in particular to a new labyrinth seal structure of an IP54 motor bearing. Background technique [0002] Generally, motor bearings with a protection level of IP54 use a skeleton seal or a labyrinth ring. The skeleton seal is a contact seal. The friction between the seal and the shaft generates heat. Since the seal is very close to the bearing, an additional heat source is superimposed on the bearing, which affects the life of the bearing. And the efficiency of the motor; although the labyrinth ring is a non-contact seal, it is difficult to process and assemble the labyrinth ring. If the labyrinth ring moves during operation, it is easy to cause friction failures. Contents of the invention [0003] The purpose of the present invention is to provide a new non-contact motor bearing sealing structure, which is a labyrinth-shaped seal, and a labyrinth structure is formed between parts to play a sealing role, and the sealin...
