Description

又、請求項４に記載した転がり軸受用内輪の固定構造物は、軸の軸方向中間部に設けた段差面と、この軸の外周面に係止した止め輪とにより、転がり軸受の内輪を軸方向両側から挟持する事で、この軸に対しこの内輪を支持固定している。
特に本発明の転がり軸受用内輪の固定構造物に於いては、前記段差面に、前記内輪の軸方向片端面を突き当てている。更に、この内輪の軸方向他端面と前記止め輪の軸方向片端面とを、互いにほぼ平行（形状誤差に基づく僅かなずれを除く。）な状態で当接させ、且つ、この止め輪の軸方向他端部を前記軸の外周面に形成した係止溝に係止し、この止め輪を前記内輪の軸方向他端面とこの係止溝との間で突っ張らせている。これにより、この内輪の軸方向変位を阻止している。

According to a fourth aspect of the present invention, there is provided a fixed structure for the inner ring of a rolling bearing, wherein the inner ring of the rolling bearing is formed by a stepped surface provided at an axially intermediate portion of the shaft and a retaining ring locked to the outer peripheral surface of the shaft. The inner ring is supported and fixed to this shaft by clamping from both sides in the axial direction.
In particularly rolling bearing inner ring of the fixed structure of the present invention, before Symbol stepped surface is abutted against the axial one end surface of the inner ring. Further, the other end surface in the axial direction of the inner ring and the one end surface in the axial direction of the retaining ring are brought into contact with each other in a substantially parallel state (excluding a slight deviation based on a shape error), and the shaft of the retaining ring and locking the direction end portion to the locking groove formed on the outer peripheral surface of the shaft, thereby Tsuppara the retaining ring between the locking groove and the axial end face of the inner ring. Thereby , the axial displacement of the inner ring is prevented.

Claims

The inner ring is supported and fixed to this shaft by clamping the inner ring of the rolling bearing from both sides in the axial direction by a step surface provided in the axial middle part of the shaft and a retaining ring locked to the outer peripheral surface of this shaft. In the fixed structure of the inner ring for the rolling bearing ,
Before SL stepped surface, Rutotomoni abut the axial one end surface of the inner ring, and an axial one end surface of the retaining ring and the other axial end face of the inner ring, is brought into contact with substantially parallel to each other, and, to lock the other axial end portion of the retaining ring in the locking groove formed on the outer peripheral surface of the shaft, that the Ru was Tsuppara the retaining ring between the locking groove and the axial end face of the inner ring the rolling bearing inner race of the fixed structure, characterized in that that prevent axial displacement of the inner ring.
