Abstract
The utility model provides a passive riding wheel axle bed of a car-type annealing furnace and relates to an axle bed used by an axle of a passive riding wheel of the car-type annealing furnace. The utility model aims at providing a passive riding wheel axle bed of the car-type annealing furnace with long service cycle, low maintenance cost and easiness in replacement of the passive riding wheel. The passive riding wheel axle bed of the car-type annealing furnace comprises an open bearing block and a high temperature wear-resisting layer, wherein the open bearing block comprises a base and a support which is arranged above the base and is connected with the base in an integrated manner, an opening is formed in the support, and the high temperature wear-resisting layer is embedded into the inner surface of the opening of the open bearing block.
Description
Technical field
The utility model relates to a kind of axle bed, particularly relates to the axle bed that the passive support roller wheel shaft of a kind of trolley type annealing furnace is used.
Background technique
What the passive support roller wheel shaft of existing trolley type annealing furnace was used is rolling bearing, in actual production process, owing to making, the recruitment shape is poor, the temperature of bearing support can be up to 700 ℃, the high temperature grease maximum operation (service) temperature of using at present is 385 ℃, the lubricating grease of adding in bearing support can burn under the high temperature of 700 ℃, the carbonization caking, cause bearing damage, be in for a long time under high temperature condition, the connection screw of bearing support also can be out of shape, when changing passive support roller, tear open not open, use rolling bearing and bearing support to exist life cycle short, maintenance cost is high, be difficult for changing the problem of passive support roller.
The model utility content
The technical problems to be solved in the utility model is to provide that a kind of life cycle is long, maintenance cost is low, change passive support roller is easy to the passive support roller axle bed of trolley type annealing furnace.
The passive support roller axle bed of the utility model trolley type annealing furnace, comprise open bearing support and high-temperature wearable layer, the bearing be connected with the pedestal one above described open bearing support comprises pedestal and is positioned at pedestal, be provided with opening on described bearing, described high-temperature wearable layer embeds the internal surface of the opening that is connected to open bearing support.
The passive support roller axle bed of the utility model trolley type annealing furnace, the material of wherein said open bearing support is steel.
The passive support roller axle bed of the utility model trolley type annealing furnace, wherein said high-temperature wearable layer thickness is 4.5mm.
In the passive support roller axle bed of the utility model trolley type annealing furnace, it is the combination of open bearing support and high-temperature wearable layer, whole bearing support and the rolling bearing of replacing, the bearing support of making at the plain carbon steel material is embedded in the high-temperature wearable layer, skin has the toughness of common iron, internal layer has high strength, high wear resistance under high temperature condition, and under the Environmental Conditions of 700 ℃, the surface hardness of the high-temperature wearable layer of internal layer can reach HRC52, life cycle is long, and maintenance cost is low; Bearing support adopts Open architecture, does not connect screw, changes passive support roller more convenient.
Below in conjunction with accompanying drawing, the passive support roller axle bed of trolley type annealing furnace of the present utility model is described further.
The accompanying drawing explanation
The structural representation that Fig. 1 is the passive support roller axle bed of the utility model trolley type annealing furnace.
Embodiment
As shown in Figure 1, the passive support roller axle bed of the utility model trolley type annealing furnace comprises open bearing support 1 and high-temperature wearable layer 2, open bearing support 1 adopts Steel material, open bearing support 1 comprises pedestal 3 and the bearing 4 that is positioned at pedestal 3 tops and is connected with pedestal 3 one, be provided with opening 5 on bearing 4, high-temperature wearable layer 2 embeds the internal surface that is connected to opening 5, high-temperature wearable layer 2 is for to weld in the mode of built-up welding the internal surface that is formed on opening 5, and be machined into the size coordinated with axle, the thickness of high-temperature wearable layer 2 is 4.5mm, surfacing electrode is selected ZD3, TN65 or other surfacing electrode.
Open bearing support does not connect screw, be convenient for changing passive support roller, open bearing support is combined integral body and is replaced rolling bearing and bearing support with the high-temperature wearable layer, avoided using rolling bearing and the bearing support cycle is short, maintenance cost is high problem, life cycle can synchronize and reach 3 months with the repair cycle of production line.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
