Embodiment Construction
[0015] Such as Figure 1~5 As shown, the name and serial number of the parts in the figure: inner ring 1, inner ring groove diameter 101, outer ring 2, outer ring groove diameter 201, stainless steel ball 3, cage 4, three-lip sealing ring 5, lip 1 501, Lip two 502, lip three 503, sealing ring skeleton 6.
[0016] Now in conjunction with the accompanying drawings, the present invention will be further described. The anti-corrosion key points of the motor bearing are that the inner ring 1, the outer ring 2, and the surface layers of the inner ring groove 101 and the outer ring groove 201 are electroplated with a layer of zinc-nickel alloy.
[0017] The main point of its anti-corrosion is to select zinc-nickel alloy material according to the characteristics of the metal. The anti-corrosion and waterproof principle of the motor bearing is: the bearing steel selected in the present invention is GCr15, and the bearing steel is GCr15. After forming, most of the matrix is austenite,...

The invention relates to a motor bearing, in particular to a zinc-coated nickel alloy motor bearing and a corrosion prevention and waterproofing method thereof. The bearing comprises an inner ring, an outer ring, a stainless steel ball, a retainer and a sealing cover, wherein the stainless steel ball and the holder are connected between the inner ring and the outer ring. Products of the same type cannot meet the requirements of waterproofness and rust prevention under the working condition of vapor. In term of corrosion prevention, the zinc-coated nickel alloy motor bearing is characterized in the inner ring and the outer ring, specifically, a surface layer which comprises an inner ring channel diameter and an outer ring diameter is coated with a layer of zinc-coated nickel alloy; In term of waterproofness, the zinc-coated nickel alloy motor bearing is characterized in that each of the two sides of the inner ring and the outer ring is connected with a three-lip sealing ring; each three-lip sealing ring is provided with a lip I, a lip II and a lip II; the lip I, the lip II and the lip III are hermetically connected with corresponding contact surfaces of the inner and outer rings respectively. The technical problem about corrosion prevention and waterproofness requirements of products of the same type is solved, the method is practicable, and products of the same type can be modified technically, updated and replaced.
Description
technical field [0001] The invention relates to a motor bearing, in particular to a zinc-nickel alloy motor bearing and an anti-corrosion and waterproof method thereof. Background technique [0002] Bearings play a load-bearing role in the rotating parts of automobiles, precision machinery, electric tools, household appliances and other equipment. When the bearing works in a general working environment and at a high speed, it usually adopts a dust cover to prevent dust and a sealing ring to seal, and the inner and outer rings and steel balls are made of bearing steel. When the working environment is poor and the sealing requirements are high, the rubber sealing ring is used for sealing, and the bearing cannot serve for a long time, especially in the working condition where water vapor passes through, the bearing cannot meet the requirements of waterproof and rust prevention. Therefore, materials and motor bearings with anti-corrosion and waterproof functions urgently need t...
