Description
Technical field
The present invention relates to a kind of vertical shaft type impact crusher, particularly relate to a kind of support system of vertical shaft and vertical shaft support device thereof of vertical shaft type impact crusher.
Background technology
Vertical shaft type impact crusher is the high speed rotation that relies on rotor, the linear velocity of utilizing rotor blade will enter material in the rotor accelerates to 60～80 metre per second (m/s)s from zero, then this material is dished out from the material casting mouth of rotor blade, the material of high-speed motion impinges upon on the anvil of crusher chamber after breaking away from rotor, disintegrating with self releases energy, and realizes broken.Because of the speed of bump material is big more, it is abundant more to disintegrate, broken just thorough more, so rotor speed is the decisive factor of vertical shaft type impact crusher breaking capacity.Owing to the granularity, quality and the blanking position that enter material in the rotor all are at random, only depend on material separating disc material can't be assigned to each accelerating cavity equably simultaneously, cause material non-uniform mass in rotor.Because of the high speed rotor rotated is sayed, the Mass Distribution inequality can make the rotor disequilibrium of high speed rotating, produces fierce vibration, also can produce non-directional and the intense impact that continues to the bearing that is connected on the vertical shaft accordingly.But domestic and international existing vertical shaft type impact crusher all adopts rolling bearing to come supporting vertical shaft at present, because of the contact site of axle rolling bearing is the some contact, corresponding its contact stress height, impact resistance is poor, rotating speed is limited by external applied load, its following life-span of condition of work that is applied in this high speed of vertical shaft type impact crusher, heavy duty and constant vibration will be reduced significantly, influence operating efficiency.Adopt rolling bearing to come supporting vertical shaft simultaneously, the vertical shaft rotating speed generally all is controlled between 1150～2400rpm, is difficult to the rotating speed requirement that reaches higher; Even in the above-mentioned range of speeds,, satisfy the rate request of acceleration material and desirable bearing life simultaneously and also compare difficulty for large rotor and small rotor; Be subjected to the restriction of rolling bearing load and rotary speed property simultaneously, existing root diameter does not almost have greater than 1100mm or less than the vertical shaft type impact crusher of 650mm root diameter usually in the scope of 650～1100mm; Therefore adopt rolling bearing to support vertical shaft, not only define the rotating speed of vertical shaft and the diameter range of rotor, and limited the crushing efficiency and the range of application of vertical shaft type impact crusher.
And existing hydrodynamic journal liquid polymers are to utilize external pressurized device (as oil pump) to be pressed into lubricating oil to sliding bearing by flow controller.Under the hydrostatic pressure effect, axle journal and bearing working surface are separated fully by one deck oil film, thereby the frictional resistance can reduce axle journal and bearing working the time reduces temperature rise and eliminates wearing and tearing, improves the rotating speed of rotating shaft and the life-span of vertical shaft support system; But use hydrodynamic journal liquid polymers all to need the special oil supply system of a cover, and the cleannes to lubricating oil are had relatively high expectations, and mainly are used in bigger lathe of the low deadweight of the middle-size and small-size lathe of various machine tools, high speed light loading and equipment, speed and equipment, lathe and equipment and high precision machine tool and equipment that the external applied load direction is certain.And for as this high speed of vertical shaft type impact crusher, heavy duty, vibration, loading direction is indefinite and the heavy-duty machinery of poor working environment does not also have promotion and application.
