The viscosity of new grease injected in a machine set is moderate at the initial stage of leaving a factory, a waste oil collecting bottle can also collect a small amount of waste grease, the waste grease is separated and separated out continuously along with base thin oil in the waste grease, the viscosity of the waste grease is higher and is gradually adhered to an inner cavity of a bearing, a grease flowing channel is narrower and narrower until the waste grease is blocked, the resistance is higher and exceeds the sealing capacity of a bearing oil seal which can only bear the pressure of 0.1-0.2 MPa, an oil seal at an orifice for injecting the new grease is burst, and the injected new grease flows out easily from the orifice. Waste oil and fat can not be cleared away in time, waste oil and fat which become invalid and become hard and waste chips generated by abrasion fill the bearing raceway for a long time, so that the bearing can not be lubricated, friction and abrasion are accelerated, the abrasion of the raceway and the damage of balls can occur after short-time work, the friction resistance moment is rapidly increased, the starting difficulty of a wind turbine generator is caused, and the wind energy utilization rate is reduced. In particular, the damage of a main shaft bearing which is always in operation can seriously generate heat, the vibration of the whole machine is aggravated, the service life of the whole machine is greatly reduced, the bearing is inevitably blocked because the lubrication cannot be obtained for a long time, and the bearing has to be replaced at high cost.
