The invention discloses a bearing greasing device which comprises a
workbench, wherein a tooling plate is arranged at the middle of the
workbench and used for the mounting of a bearing; a greasing
machine is arranged above the tooling plate; a
rotating disc is arranged at the upper end of a greasing head of the greasing
machine; through the rotation of the
rotating disc, the greasing head is further driven to perform
circular motion; a greasing
brush is arranged at the lower end of the greasing head; and
grease in the greasing
machine flows into the greasing
brush through the greasing head. According to the bearing greasing device disclosed by the invention, the greasing
brush is driven by the arranged
rotating disc to perform
circular motion, and the greasing brush gets in touch with eachroller on a bearing through the rotation, thereby achieving the greasing effect; the greasing
processing can be
fully automated and the manual operation of a worker is not needed; the greasing efficiency is high; and the precision can be guaranteed. The invention further discloses a clearing method adopted before greasing of the bearing. When the bearing is heated, the temperature of the bearingis increased to 280 DEG C through a started-up heating device, thereby melting the
grease; then, the molten
grease is cleared from the bearing through the pressurized jet operation of a jet
pipe and aclearing
pipe; and accordingly, the purpose of quickly clearing the grease is fulfilled, the speed is high, and the efficiency is high.
