Regarding the pinion shaft.

溶射法等が採用されている。However, in differential gears, especially in front-wheel drive cars, the differential gear's lubricating oil is shared with transmission oil, and as is known, transmission oil has a low viscosity, and as a result of being lubricated with this low-viscosity oil, the oil film on the pinion shaft surface is cut off. , wear, scuffing (galling), seizure, etc. occur. Therefore, in order to deal with this problem, surface hardening has conventionally been performed on at least the friction sliding surface 3a of the pinion shaft 3 that contacts the pinion gear, and soft nitriding, carburizing, molybdenum spraying, etc. have been adopted as the surface hardening treatment method. ing.

生する。In addition, the surface treatment layer formed by molybdenum spraying has a weak bond strength between the molybdenum spray particles, so the strength of the sprayed layer as a whole is low.
There is a drawback in that abrasion, a phenomenon in which highly hard particles in the sprayed layer fall off and abrade the mating material, occurs. In other words, since molybdenum has a high melting point of 2620°C, the molybdenum metal is not sufficiently dissolved during thermal spraying, and the bond strength between the sprayed particles is weak, causing abrasion phenomenon during differential application, resulting in the hardness of the molybdenum particles falling off. Since the voltage is extremely high at 600 to 650 HV, scuffs occur on the sliding surface of the pinion gear, and peeling occurs in the sprayed coating on the pinion shaft side, and as this phenomenon progresses, seizure occurs.

。Furthermore, molybdenum sprayed material is an expensive alloy and is not commonly used for surface treatment of pinion shafts. However, metal thermal spraying, especially molybdenum thermal spraying, has the property of the sprayed layer that the voids formed between metal particles have the function of retaining lubricating oil, possessing self-lubricating properties, and increasing wear resistance. It has advantages. In view of the above-mentioned problems with surface-treated pinion shafts of differential gears, the present inventors have devised the present invention to solve the problem. By taking advantage of the above advantages and further promoting them, we have effectively solved the above problems.

明しよう。The content of molybdenum is 50-70%, which is 50-70%.
Since it is an alloy containing 0% molybdenum, the self-lubricating property of molybdenum is lost, and the wear resistance can be sufficiently satisfied. The porosity in the sprayed layer formed with this sprayed material is 5 to 12%, which is about the same as that of molybdenum, and the synergistic effect with these materials provides excellent wear resistance, abrasion resistance, scuff resistance, and seizure resistance. A coating with excellent properties can be obtained, and a pinion shaft for a differential device with excellent properties can be obtained. Next, a specific example of the pinion shaft of the present invention will be described.

A mesh) is thermally sprayed onto at least the pinion gear sliding surface 3a of the pinion shaft 3 by plasma spraying to form a coating that forms the sliding surface. A characteristic of plasma spraying is that it uses an inert gas such as argon, so the sprayed coating is difficult to oxidize, unlike methods that use a general gas flame. This can prevent the formation of an oxide intermediate layer that significantly weakens adhesion. Therefore, it has the effect of stabilizing the adhesion strength to the material of the coating, that is, the surface of the pinion shaft, and further increasing the strength of the entire thermal sprayed coating. Next, the outer periphery of the portion of the pinion shaft on which the thermally sprayed coating has been formed is ground to a predetermined size using a diamond grindstone to obtain a pinion shaft formed to the final size.

，示す。In the case of the pinion shaft according to the present invention, the hardness is preferably 450 to 500 HV, and in order to obtain this hardness, the molybdenum content is 50 to 70%.
If the hardness is 0% or less, the hardness distribution of the obtained coating will be 450 HV or less, and the amount of wear on the pinion shaft will be greater than the amount of wear on the pinion gear. Moreover, when the content of molybdenum exceeds 70%, the hardness of the obtained film is 50%.
The hardness distribution of 0HV or more increases, causing scuffs on the pinion gear surface. Therefore, the content of molybdenum is preferably 50 to 70% from the viewpoint of compatibility with the mating pinion gear. Next, the results of a test conducted to compare the pinion shaft of the present invention obtained above with a pinion shaft coated with a sprayed coating using a molybdenum spraying method will be shown.
