Graphite bearings are carbon bearings developed and developed on the basis of metal bearings in response to the performance requirements of mechanical equipment, with graphite as the main base material.

[0003] At present, graphite rings are one of the more important parts in graphite bearings. During the sintering process, pyrolysis substances will be discharged from the graphite rings, resulting in pores. Porous carbon graphite rings cannot be used as mechanical sealing rings, so they need to be impregnated. After the impregnation, the graphite rings need to be cured to become impermeable materials. Most of the current curing devices cure a batch of graphite rings at one time, which is not conducive to adding graphite rings that have been impregnated at any time. In this way, it is necessary to wait for a period of time before curing, which affects the processing efficiency of the graphite rings. For this reason, a precision graphite bearing curing device is proposed. Utility Model Content
