DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] The outer ring 1 of the bearing is provided with a uniform and rapid oil injection mechanism, which is used to uniformly and rapidly inject oil into the oil storage space;

[0030] The uniform and rapid oil injection mechanism comprises a plastic sealing cover 3. A stepped annular groove 2 is provided on one side of the outer surface of the bearing outer ring 1. The plastic sealing cover 3 is sleeved in the stepped annular groove 2. The space between the stepped annular groove 2 and the plastic sealing cover 3 forms an oil delivery channel.

[0031] The outer surface of the bottom wall of the stepped annular groove 2 is provided with a plurality of oil inlet holes 13, which are evenly arranged in a circular array, and the oil inlet holes 13 are all tangent to the inner wall of the bearing outer ring 1;

[0032] The oil delivery channel is connected to the oil storage space through the oil inlet hole 13 , which enables the lubricating oil to circulate in the oil storage space along the inner wall of the bearing outer ring 1 when rushing into the oil storage space from the oil inlet hole 13 .

[0033] Furthermore, an oil filling nozzle 4 is fixedly connected to the outer surface of the plastic sealing cover 3, and the oil filling nozzle 4 is used for oil filling.

[0034] Furthermore, an oil storage bag 8 is sleeved on the oil filling nozzle 4, and lubricating oil is stored in the oil storage bag 8. The oil storage bag 8 is a prior art and will not be described in detail here.

[0038] Furthermore, during use, when the lubricating oil in the oil storage space is consumed too much, the oil storage bag 8 storing the lubricating oil is placed on the oil filling nozzle 4, and then the oil storage bag 8 is squeezed hard, and the lubricating oil in the oil storage bag 8 enters the oil filling nozzle 4, pushing the ball 5 to the limit block 7, and then the lubricating oil will rush into the stepped annular groove 2 from the gap between the multiple limit blocks 7. When the stepped annular groove 2 is filled with lubricating oil, the pressure in the stepped annular groove 2 reaches equilibrium, and the lubricating oil begins to be evenly rushed into the oil inlet channel 13.

When the stepped annular groove 2 is filled with lubricating oil, the pressure in the stepped annular groove 2 reaches equilibrium, and the lubricating oil begins to be evenly rushed into the oil inlet channel 13. At this time, since the multiple oil inlet channels 13 are tangentially arranged to the inner wall of the bearing outer ring 1, when the lubricating oil rushes into the oil storage space from the oil inlet channel 13, it can circulate in the oil storage space along the inner wall of the bearing outer ring 1, so that the lubricating oil can quickly and evenly fill the oil storage space and wrap the ball 10.
