Abstract
A device for heating a bearing race mounted on a shaft including a quartz halogen lamp for heating the bearing race and a reflector for reflecting heat from the quartz halogen lamp towards the bearing race.
Claims20
A device for heating an inner race of a bearing arrangement mounted on a shaft, comprising:
- a substantially ring-shaped quartz halogen lamp for heating the inner race;
- a substantially ring-shaped reflector open to the quartz halogen lamp for reflecting heat axially with respect to the shaft from the quartz halogen lamp towards the inner race and for reflecting heat away from the shaft;
- and
- a cylindrical sleeve inside the substantially ring-shaped reflector for mounting the substantially ring-shaped reflector on the shaft, wherein the cylindrical sleeve includes a thermally non-conductive material.

A device for heating a first angular contact inner race or a second angular contact inner race of an angular contact ball bearing mounted on a shaft, comprising:
- a substantially ring-shaped quartz halogen lamp having an exposure to the first angular contact inner race or the second angular contact inner race;
- a substantially ring-shaped reflector open to the quartz halogen lamp and attached to the quartz halogen lamp for reflecting heat axially with respect to the shaft from the quartz halogen lamp towards the first angular contact inner race or the second angular contact inner race and for reflecting heat away from the shaft;
- a cylindrical sleeve inside the substantially ring-shaped reflector for mounting the substantially ring-shaped reflector on the shaft, wherein the cylindrical sleeve includes a thermally non-conductive material;
- and
- a housing for enclosing the quartz halogen lamp and the reflector.
2 more elements
A device for heating a roller bearing inner race of a roller bearing mounted on a shaft, comprising:
- at least one substantially ring-shaped quartz halogen lamp having an exposure to the roller bearing inner race, wherein the exposure is directed radially to the shaft;
- a substantially ring-shaped reflector open to the quartz halogen lamp and attached to the at least one quartz halogen lamp for reflecting heat radially with respect to the shaft from the at least one quartz halogen lamp towards the roller bearing inner race;
- a cylindrical sleeve inside the substantially ring-shaped reflector for mounting the substantially ring-shaped reflector on the shaft, wherein the cylindrical sleeve includes a thermally non-conductive material;
- and
- a housing for enclosing the at least one quartz halogen lamp and the reflector.
