Description
Technical Field
The utility model relates to a blast furnace tapping machine equipment technical field, concretely relates to novel blast furnace stokehold tapping machine wheel.
Background
The tapping machine is a key device for blast furnace front production, whether the tapping machine is normally done or not directly influences the punctuality of iron discharge of the blast furnace, and meanwhile, the tapping machine is also a key device for restricting the stable operation of the blast furnace, so that the normal operation of the tapping machine is very important. The self-lubricating copper sleeve is arranged in the wheel of the tapping machine used for the furnace front opening of the steel furnace, mechanical friction is generated in the running process of the wheel, a lubricating system is not used, the copper sleeve is quickly abraded, and the gap between a wheel shaft and a bottom plate is increased. The time of getting on the production line of the spare wheel parts is short, the spare wheel parts need to be replaced once every two months on average, and the replacement needs about 1.5 hours every time, so that the spare part consumption is more, the task of maintenance personnel is increased, and meanwhile, the normal operation of blast furnace front tapping is also not facilitated.
SUMMERY OF THE UTILITY MODEL
The not enough of the above-mentioned opening locomotive wheel easy damage to prior art, the utility model provides a novel blast furnace stokehold opening locomotive wheel is through setting up tapered roller bearing between wheel and axletree to reduced the coefficient of friction between wheel and the axletree, opening locomotive wheel accident rate greatly reduced, the effect is comparatively obvious.
The technical scheme of the utility model as follows:
the utility model provides a novel blast furnace stokehold opening locomotive wheel, includes wheel and base, the wheel passes through the axletree and installs on the base its characterized in that: a tapered roller bearing is arranged between the wheel and the wheel shaft.
Preferably, the front end of the wheel shaft is provided with a shaft snap spring, the shaft snap spring and the tapered roller bearing are in interference fit, and the wheel shaft is fixedly connected with the base. The shaft snap spring obtains a suitable working clearance of the tapered roller bearing by adjusting the adjusting range of the shaft snap spring on the premise of ensuring interference fit, so that the bearing is prevented from being locked and failing.
Preferably, a wheel cover is arranged on the outer side of the wheel, and the wheel cover are fixed through bolts.
Preferably, an oil filling hole is formed in the wheel shaft, and the tapered roller bearing is filled with lubricating oil through the oil filling hole.
Preferably, the upper part of the wheel is provided with a tapered inner surface adapted to the tapered roller bearing.
Preferably, the wheel is of a cylindrical structure, and the side edge of the wheel is provided with a limiting extension.
The tapered roller bearing has the advantages that the rollers are arranged in parallel, so that the inclination of the rollers or the mutual friction between the rollers can be prevented, and the increase of the rotating torque is effectively prevented; meanwhile, the tapered roller bearing can bear radial load and unidirectional axial load, and can effectively adapt to the load on a blast furnace front tapping machine, so that the adaptability and the durability are improved.
The utility model has the advantages that:
the utility model relates to a rationally novel, it is safe convenient. Reduce the tapping machine wheel and damage, prolong the online life of wheel. Meanwhile, the production rhythm in front of the blast furnace is ensured to be stable under the advantage of reducing the work of maintainers. The average service life of the front wheels of the blast furnace after the transformation is improved to 8-12 months from the original 2 months.
Furthermore, the utility model relates to a principle is reliable, and simple structure has very extensive application prospect.
