The existing sealing bearing structure has short service life, the problem of lubricating grease leakage of the sealing bearing can occur sometimes, and the sealing bearing is complex and complicated to assemble and is used for bearings with low rotating speed. In the prior art, a single-shaft automatic lathe is adopted for machining in a forming process, when cutting is performed, because Vc is pi DN/1000, if constant-speed cutting is performed, the diameter is gradually reduced when a cutter is closer to an axis, the linear velocity of the cutter is gradually reduced, and the linear velocity is reduced to 0 when the cutter is closer to the center, so that a cutting ring which slightly protrudes out of an end face is generated when the cutter is used for squeezing and breaking a workpiece instead of cutting the workpiece. When the plane is ground in a soft mode, a vertical shaft surface grinding machine is used for grinding, a cutting ring is firstly contacted with a grinding wheel during grinding, and the problems of plane taper and out-of-parallel tolerance caused by the influence of the cutting ring are caused because the rotation plane of the grinding wheel is not parallel to the working surface. The prior art is in car U type groove process, and the three-jaw chuck is with internal diameter and a side end face location, adopts shaping lathe tool processing turning, and shaping sword type is the same with the cell type, and 3 faces of cutting edge all participate in the cutting, and cutting resistance is big in the cutting process, easily produces the work hardening, and the heat dissipation difficulty, these problems can cause that knife tip department cutting temperature is high, the smear metal that the cutting edge produced bonds, have aggravated the wearing and tearing of cutter, influence machined surface quality, make U type groove roughness not conform to the design requirement. In addition, the cuttings are not easy to curl and break, and can be extruded and clamped at the side edge of the forming cutter to cause the plastic deformation and bending of the side wall of the pulley, and the amplitude and height size of the bearing, the position and size of the U-shaped groove and the jumping of the center of the U-shaped groove to the end surface are influenced. In the prior art, a numerical control lathe CY-K500 device is adopted in a U-shaped groove, the device does not have a rotary cutter tower, only one cooling spray gun is arranged at the terminal of a cooling system of the device, and the cutter point is not fully cooled by cooling liquid due to the fact that the moving process of a cutter and a water spray pipe is inconsistent, so that the service life of a blade is greatly reduced, and particularly when a deep groove surface is machined, the surface roughness of the groove is poor and the surface quality is difficult to control due to the poor cooling state of the cutter head.
In conclusion, in the prior art, the size and the precision of the U-shaped groove of the pulley bearing do not meet the design requirements, and the U-shaped groove is machined by adopting a numerically controlled lathe CY-K500 device, the device does not have a rotary cutter tower, only one cooling spray gun is arranged at the terminal of a cooling system of the device, and the problem that the moving process of a cutter and a water spray pipe is inconsistent exists.
