Process and apparatus for assembling multiple rolling bearing and a rotating member onto a shaft
First Claim
1. Apparatus for assembling axially inner and outer rolling bearings and a rotating member onto a shaft, the rotating member adapted to receive the rolling bearings and be supported by the rolling bearings for rotation with respect to the shaft, the rotating member having a spacer adapted to maintain a desired separation between the rolling bearings, the apparatus comprising:
- a pilot stud coaxially aligned with an end of the shaft and having a stud diameter less than a diameter of the shaft, the rolling bearings and the rotating member being mounted on the pilot stud; and
a ram aligned with the shaft and having an abutment member adapted to engage the outer rolling bearing, movement of the ram toward the shaft causing the abutment member to move the outer rolling bearing against the spacer and onto the shaft, and the movement of the ram toward the shaft causing the spacer to move the inner rolling bearing onto the shaft so that a single stroke of the ram mounts the rolling bearings and the rotating member onto the shaft.

Abstract
Apparatus includes a pilot stud and a ram. The pilot stud is aligned with an end of a shaft. A rotating member is adapted to receive axially inner and outer rolling bearings and be supported by the rolling bearings for rotation with respect to the shaft. The rotating member has a spacer for maintaining a desired separation between the rolling bearings. The rolling bearings and the rotating member are mounted on the pilot stud. The ram has an abutment member that is adapted to engage the outer rolling bearing. The ram is aligned with and moved toward the shaft. Movement of the ram toward the shaft causes the abutment member to move the outer rolling bearing against the spacer and onto the shaft. Also, this movement of the ram toward the shaft causes the spacer to move the inner rolling bearing onto the shaft. So, a single stroke of the ram mounts the rolling bearings and the rotating member onto the shaft. Preferably, the inner and outer rolling bearings each include a cone, a cup, and a tapered roller set adapted to be positioned for rolling between the cone and the cup. The abutment member preferably includes a radially inner abutment for engaging the outer cone and a radially outer abutment for engaging the outer cup. The radially inner and outer abutments have different axial dimensions for maintaining a desired axial spacing between the outer cone and cup.

8. A process for assembling axially inner and outer rolling bearings and a rotating member onto a shaft, the rotating member adapted to receive the rolling bearings and be supported by the rolling bearings for rotation with respect to the shaft, the rotating member having a spacer adapted to maintain a desired separation between the rolling bearings, the process comprising the steps of:
-
aligning a pilot stud with an end of the shaft; mounting the rolling bearings and the rotating member on the pilot stud; aligning a ram with the shaft, the ram having an abutment member adapted to engage the outer rolling bearing; and moving the ram toward the shaft in order to cause the abutment member to move the outer rolling bearing against the spacer and onto the shaft, and to cause the spacer to move the inner rolling bearing onto the shaft so that a single stroke of the ram mounts the rolling bearings and the rotating member onto the shaft. - View Dependent Claims (9, 10)
