PROBLEM TO BE SOLVED: To provide a wheel bearing device and an assembly method for the wheel bearing device capable of applying an appropriate axial load to a bearing, while preventing fretting wear-resistant agent, which is interposed between an axle and an inner ring of the bearing and may be protruded during assembly and remained to be solidified, from causing difficulty in tightening.SOLUTION: A wheel bearing device is mounted onto an axle 1, and supports a hub 2 for mounting a wheel. A bearing 3 in the wheel bearing device comprises: an outer ring 31 with double row outer raceway surfaces 31a integrally formed on an inner periphery, and with the hub 2 fitted or integrally formed on an outer periphery; a plurality of inner rings 30A and 30B each having an inner raceway surface 30a formed on an outer periphery so as to face each of the double row outer raceway surfaces 31a; and double row rolling elements 32 housed rotatably between the outer raceway surfaces 31a and the inner raceway surfaces 30a. Fretting wear-resistant agent 40 is coated on the inner peripherals of the inner rings 30A and 30B. The inner rings 30A and 30B are fitted onto the axle 1.SELECTED DRAWING: Figure 2

    【課題】 車軸と軸受の内輪との間に介在させるフレッティング摩耗防止剤が両者の組付け時にはみ出してそのまま固化し、締付けの障害となることが回避できて、軸受に適正な軸力を負荷することができる車輪用軸受装置、および車輪用軸受装置の組立方法を提供する。【解決手段】 車輪用軸受装置は、車軸1に設置され車輪取付用のハブ2を支持する。車輪用軸受装置の軸受3は、内周に複列の外側軌道面31aが一体に形成され外周にハブ2が嵌合するか、または一体化された外輪31と、外周に複列の外側軌道面31aに対向する内側軌道面30aが形成された複数の内輪30A,30Bと、外側軌道面31aと内側軌道面30a間に転動自在に収容された複列の転動体32とを有する。内輪30A,30Bの内周面にフレッティング摩耗防止剤40が塗布され、車軸1に内輪30A,30Bが嵌合される。【選択図】 図2
