The heat dissipation oil baffle disc of current patent number CN201922439101.X, its whole is the ring form, and the circular form hole is the hole fitting surface of cooperation motor shaft, oil baffle disc axle is to the inboard by the hole fitting surface along the first part of oil baffle disc radial extension for cyclic annular convex surface, continues the part of radial extension by cyclic annular convex surface for cyclic annular concave surface, continues the part of outside extension by cyclic annular concave surface to be cyclic annular inclined plane, evenly is equipped with three boss on cyclic annular concave surface. The existing oil baffle disc is provided with an annular concave surface, the oil storage area is limited, the end face of a bearing cannot be completely covered, the end face of the bearing is oiled under the condition that a boss rotates, the resistance of oil scraping is large, lubricating grease cannot be uniformly coated on the end face of the bearing, and the cooling effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems and provide a high-performance low-resistance heat dissipation oil baffle disc, so that the oil scraping resistance of the oil baffle disc is reduced, lubricating grease is uniformly scraped on the end face of a bearing, and the oil baffle disc has good heat dissipation performance. In order to achieve the purpose, the technical scheme of the utility model is as follows:

the high-performance low-resistance radiating oil baffle disc comprises an inner ring part which is matched and sleeved with a motor shaft, a first oil storage ring which is provided with an outer periphery of the inner ring part and protrudes outwards, a stress ring which is arranged on the periphery of the first oil storage ring, a second oil storage ring which is arranged on the periphery of the stress ring and protrudes outwards, an outer baffle ring which is arranged on the periphery of the second oil storage ring and inclines inwards, and a plurality of oil scraping sheets which are arranged on the stress ring and are arranged in a concentric spiral manner; the inner ring portion and the oil scraping sheet are attached to abut against the end face of the bearing, and the first oil storage ring and the second oil storage ring face the end face of the bearing.

Specifically, the first oil retainer and the second oil retainer have the same axial depth.

Specifically, a gap is reserved between each of the first oil storage ring and the second oil storage ring and the end face of the bearing.

Specifically, the end part of the oil scraping sheet is flush with the inner side surface of the stress ring.

Specifically, the end part of the oil scraping sheet is a smooth contact surface.

Specifically, the center of the inner ring part is provided with an inner hole assembling ring matched with the motor shaft.

Compared with the prior art, the high-performance low-resistance heat dissipation oil baffle disc has the beneficial effects that:

the stress ring and the oil scraping sheet are attached to the end face of the bearing, the oil scraping sheet scrapes redundant grease on the end face of the bearing, the grease on the end face of the bearing is uniform, the grease is pushed into the first oil storage ring and the second oil storage ring, and the grease is continuously coated on the end face of the bearing again by the oil scraping sheet along with long-time use, so that the grease coating area on the end face of the bearing is increased, and the heat radiation performance is improved; the oil scraping sheets arranged in a concentric spiral manner can effectively reduce the resistance of the contact surface, improve the air flow in the rotating process and accelerate the heat dissipation.
