Advantageous effects
Compared with the prior art, the utility model has the beneficial effects that:
(1) according to the utility model, the annular groove for placing the steel ball is provided with the plurality of thin grooves, so that lubricating oil can enter the thin grooves when the lubricating oil is injected into the bearing, the lubricating oil has certain viscosity, the lubricating oil can stay for a longer time when entering the thin grooves, the lubricating time can be greatly prolonged after the lubricating oil is injected once, and meanwhile, the liquid has certain tension, so that the lubricating oil can stay for a longer time in the thin grooves, the bearing can be lubricated for a long time, meanwhile, capillary force can be generated between the thin grooves and the lubricating oil, the capillary force refers to the combined action of the suction force between the capillary wall and water molecules and the surface tension of water, and further, the lubricating oil can stay in the thin grooves for a long time, and conditions are provided for long-time lubrication of the bearing.
(2) In the utility model, the oil absorption line is simultaneously and well placed in the thin groove, lubricating oil can be better kept in the thin groove through the oil absorption line without dripping due to vibration force and inertia generated by the rotation of the bearing, the oil absorption line also has a capillary action, the lubricating oil can be guided to the ball of the bearing, as long as the ball can contact the oil absorption line, and the existing bearing can also use solid lubricating oil, namely: the grease, but the grease that is located the slot can not contact the ball and play the lubrication effect, therefore the slot can lose the effect, and adds the oil absorption line in the slot, just can solve above-mentioned problem, and the oil absorption line is soaked by the grease, and the ball contacts the oil absorption line and can play the lubrication effect equally.
