Abstract
The utility model discloses an annular milling type vertical flour mill hammer wheel bearing wind-swept self cooling device, wherein a hammer wheel is mounted on a swing arm through a hammer wheel shaft, a bearing is mounted between the hammer wheel and the hammer wheel shaft, and the hammer wheel shaft is a hollow shaft. The annular milling type vertical flour mill hammer wheel bearing wind-swept self cooling device is characterized in that due to the fact that the hammer wheel rotates together with the swing arm around a main shaft at uniform velocity, a wind shield with a bearing bush structure is machined on the top, on which the bearing is mounted, of the hollow hammer wheel shaft, air flow which comes vertically can change direction and flow along an inner hole of the hollow hammer wheel shaft, just like a cooling blower cools the hollow hammer wheel shaft and the bearing; the size of wind shielding leaves can be adjusted, so that the strength of the air flow can be changed; wind sweeping can be directly used to cool the bearing part, the shortcoming of death by burning of the bearing due to excess temperature is effectively overcome, continuous work of the flour mill is achieved, and service efficiency of machines is improved.
Description
Technical field
The utility model relates to a kind of ring stone roller type vertical grinder hammer wheel.
Background technology
Hammer wheel on the existing ring stone roller type flour mill generally has spinning motion, in the hammer wheel rotor bearing is housed all, rotates around the hammer wheel shaft like a cork to realize the hammer wheel.Because hammer wheel constantly rolls, impacts material grinding on the ring inwall, the hammer wheel generates heat because of friction, and when moving continuously, hammer wheel internal bearings can burn out stuckly because of excess Temperature, and therefore bearing lost efficacy.This hour hammer wheel can only revolve round the sun and can not rotation; the hammer wheel can only play the effect of scraper, and the hammer wheel directly produces sliding friction with grinding ring, and annular hammer wheel is worn into flat fast; must shut down change, this also is to encircle at present the main cause that stone roller type vertical grinder can not continuous operation.
The utility model content
The purpose of this utility model provides a kind of ring stone roller type vertical grinder hammer wheel bearing position and sweeps the wind self-cooling device, and this device can prevent from hammering into shape the defective that wheel bearing exists because of excess Temperature effectively.
The technical solution of the utility model is, a kind of ring stone roller type vertical grinder hammer wheel bearing is swept the wind self-cooling device, by the hammer wheel shaft hammer wheel is housed in swing arm, between hammer wheel shaft and hammer are taken turns bearing is housed, and the hammer wheel shaft is hollow shaft.
On the hammer wheel shaft, be equipped with and sweep windshield plate.
Bearing is fixed on the hammer wheel shaft by locking nut, in the lower end of bearing baffle plate is housed, and between baffle plate and the hammer wheel shaft sliding sleeve is housed.
Between hammer wheel and hammer wheel shaft upper end dust cap is housed, dust cap is fixed on the hammer wheel, between dust cap and hammer wheel shaft sidewall sealing ring is housed.
The utlity model has following technique effect, because the hammer wheel at the uniform velocity rotates around main shaft together with swing arm, top at the hollow hammer axle that fills bearing is processed into one with the deep bead of bearing bush structure, allowing the air-flow of vertically coming change direction flows along the endoporus of hollow hammer axle, just as a cooling blower cools off hollow hammer axle and bearing, the keep out the wind size of leaf of adjustment, can change the size of air-flow, direct utilization is swept wind bearing portion is cooled off, effectively solved the defective that bearing is burnt to death because of excess Temperature, realize the continuous operation of grinding machine, improved the service efficiency of machine.
