Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil baffle rings, in particular to an oil baffle ring with high-efficiency heat dissipation. Background Art
[0002] The oil retaining ring is located at the outer edge of the pressure cover at both ends of the bearing box and is fixed on the shaft with screws and rotates with the shaft. The oil retaining ring plays the role of preventing the lubricating oil from being thrown out. The oil retaining ring is installed on the rotating shaft and rotates synchronously with the shaft. The centrifugal force generated by the rotation will throw the excess grease back to the lubrication part of the rotating shaft, so that the grease can be fully utilized. It is a very important motor part. The motor drives the rotating shaft to rotate during operation. A large amount of heat will be generated when the working end of the rotating shaft processes the workpiece. If the heat on the rotating shaft is not dissipated in time, the viscosity of the lubricating oil in contact with the rotating shaft will decrease due to the increase in temperature, resulting in leakage of the lubricating oil, thereby causing oil leakage. If the oil leakage is not discovered in time, the motor where the rotating shaft is located will have the consequence of increased temperature and burning, affecting the normal use of the motor. Therefore, an oil retaining ring with efficient heat dissipation is designed to solve the above problem. Utility Model Content

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:
[0013] 1. The utility model is provided with an annular groove, which is opened on the oil deflector ring body to increase the contact area between the oil deflector ring body and the air, thereby increasing the heat dissipation effect of the oil deflector ring body. Through the provision of heat dissipation fins, the heat on the oil deflector ring body is transferred to the heat dissipation fins and dissipated into the air through the heat dissipation fins, thereby further increasing the heat dissipation effect. During use, the oil deflector ring body rotates with the shaft, so that the heat dissipation fins rotate. The rotation of the heat dissipation fins fans the hot air around the oil deflector ring body away from the oil deflector ring body, thereby preventing the hot air from gathering around the oil deflector ring body, thereby further increasing the heat dissipation effect.

[0025] By providing an annular groove 101, which is opened on the oil deflector ring body 1, the contact area between the oil deflector ring body 1 and the air is increased, and the heat dissipation effect of the oil deflector ring body 1 is increased. By providing the heat dissipation fins 102, the heat on the oil deflector ring body 1 is transferred to the heat dissipation fins 102, and dissipated into the air through the heat dissipation fins 102, thereby further increasing the heat dissipation effect. During use, the oil deflector ring body 1 rotates with the shaft, so that the heat dissipation fins 102 rotate, and the heat dissipation fins 203 rotate to fan the hot air around the oil deflector ring body 1 away from the oil deflector ring body 1, thereby preventing the hot air from gathering around the oil deflector ring body 1, thereby further increasing the heat dissipation effect.

[0029] In this embodiment, the length of the heat dissipation fin 102 is greater than the depth of the annular groove 101, and the heat dissipation fin 102 extends out of the annular groove 101, so that the heat dissipation fin 102 can fan the hot air around the oil deflector body 1 to the side away from the oil deflector ring, preventing the hot air from gathering at the oil deflector ring body 1, thereby further increasing the heat dissipation effect.
