Technical Field
The utility model relates to the technical field of sintering machine equipment, in particular to a head star wheel of a sintering machine.
Background
The existing sintering operation area usually uses a straight-bar sintering machine with 90 square meters, and the existing sintering machine has serious deviation phenomenon. The deviation causes the sintering trolley to extrude the track and the slideway in the running process, the wheel is frequently damaged, the track is seriously worn, the abrasion of the moving slideway and the static slideway is inconsistent, the oil nozzle is frequently blocked and lubricated badly, the deviation gnaws the abrasion of the slideway, the slideway can not be replaced when the service life is not reached, the load of a transmission part is increased, the motor is overloaded and runs for a long time, the frequent maintenance cost of accidents is increased, the damage and replacement cost of the trolley, the wheel, the slideway and the oil plate caused by the deviation is up to millions yuan, the air leakage rate is increased caused by the deviation of the trolley, the negative pressure of the sintering machine is reduced, the output quality of the sintering machine is influenced, and the production cost is increased.
As shown in fig. 1, current sintering machine head star gear includes star gear assembly 2, the 2 outsides of star gear assembly are provided with pinion rack 3, pinion rack 3 cooperatees with sintering platform truck 1's left and right sides wheel to drive sintering platform truck 1 and remove, do not have the navigation key because of the wheel hub of star gear assembly, the installation accuracy is not enough, angular deviation appears in the installation, lead to pinion rack 3 not synchronous, asynchronous because of pinion rack 3, when sintering platform truck gets into the head bend, control pinion rack 3 and sintering platform truck 1 about wheel meshing inconsistent, the orbit that makes sintering platform truck 1 get into the bend changes, the off tracking appears when leading to sintering platform truck to get into horizontal track.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a sintering machine head star wheel which comprises a star wheel assembly, wherein toothed plates which are uniformly distributed and in a scattering shape are arranged on the outer side of the star wheel assembly, the toothed plates are matched with a left wheel and a right wheel of a sintering trolley, and an eccentric thickening part is arranged on one side of each toothed plate.
Preferably, the toothed plate is provided with a weight port.
Preferably, the eccentric thickening part and the toothed plate are integrally formed.
Preferably, the eccentric thickening has a thickness of 3 mm.
Preferably, the toothed plate is made of 40 CrMn.
The beneficial effects of the utility model are embodied in the following aspects:
according to the utility model, under the current working condition, the left toothed plate and the right toothed plate of the star wheel at the head part of the sintering machine are changed, the eccentric thickening part is adopted to ensure that the output force of the toothed plates is uniform, when the sintering machine enters the head part curve, the left toothed plate and the right toothed plate synchronously advance with the left wheel and the right wheel of the trolley, so that the running track of the sintering trolley is stable, the trolley wheels are not abraded any more, the upper sliding plate and the lower sliding plate are abraded uniformly and smoothly, the phenomena of deviation and gnawing of grinding wheels and the like are avoided, the integral air leakage rate of the sintering machine is reduced, the negative pressure is increased, the utilization coefficient of the sintering machine is increased, the daily output is increased, and the cost of sintering ore is reduced.
The pinion rack adopts 40CrMn, changes the pinion rack material, increases the weight port of pinion rack, changes pinion rack installation form, under the prerequisite that does not change pinion rack intensity, reduces pinion rack weight, reduces pinion rack stress concentration, and the adoption of weight port makes the pinion rack whole light, the equipment fixing of being convenient for.
