Abstract
The utility model relates to a wearing-resistant roller which is used as a roller way of a steel rolling conveyer. The utility model is characterized in that the roller is assembled into the integration by a casing and an inner sleeve of the roller, wherein the central position of the inner sleeve is processed with a shaft hole which is connected with a transmission shaft and is embedded into a hole cavity at one end of the roller casing by adopting a hot loading method. The roller casing can be cast in a centrifugal mode, processed and made of wearing-resistant high-chromium cast iron, and the inner sleeve is formed by processing the common cast iron. By adopting the sheathing structure, the utility model can reduce the machine processing quantity of the roller and can reduce the material cost of the roller on the basis that the wear resistance of the roller is ensured.
Description
The utility model relates to a kind of Wearing-resistant roller, and this roller mainly is suitable for using as steel rolling conveyer roller-way.
The roller that uses on the steel rolling conveyer roller-way is to adopt the rich chromium cast iron integral casting forming mostly at present, makes roll body through machined again.Although this roller has the good performance of having strong resistance to heat and hard wearing, because roller system adopts high-chromium material to make, the machined working angles is very difficult, moreover, and shortcoming such as above-mentioned roller also exists roll body material cost higher, and weight is big.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of Wearing-resistant roller that is assembled by roller shell and interior cover is provided.
The utility model above-mentioned purpose is finished like this.
A kind of Wearing-resistant roller is characterized in that this roller is assembled into one by hollow roll shell and interior cover, and interior cover centre is processed with the axis hole that is connected with power transmission shaft, and interior cover integral body is inlaid in the roller shell one stomidium chamber with hot charge practice.The basic contour structures of cover is cylindrical in the above-mentioned roller, and cover was fit to be sleeved on than in the short roller shell vestibule in this was cylindrical; When the roller shell sizes is longer, in order to strengthen the power that is fitted to each other between roller shell and the interior cover, cover assembling one end is processed with the annulus sidewall in the above-mentioned roller, the external diameter of this sidewall is identical with the cavity internal diameter of roller shell, also adopt the roller internal diameter of outer cover suitably to be expanded roller shell heating means, then interior cover is inlaid in the roller shell vestibule.
The axis hole that cover is connected with power transmission shaft in the above-mentioned roller preferably is processed into Rotary-table, and its tapering was generally 1: 10.
Wearing-resistant roller provided by the utility model, its roller shell is still selected high chromium cast iron material for use, adopt the centrifugal casting mode to process, cover then adopts plain cast iron material casting in the roller, with machining mode its axis hole and external diameter are pressed designing requirement machine-shaping then, adopt hot charge practice that roller shell and interior cover are assembled into one at last, above-mentioned assembly structure can make roller keep on original rich chromium cast iron roller wearability and the heat resistance basis, promptly made things convenient for the whole machine-shaping of roller, and can reduce the machined workload, reduce material cost.
Introduce the utility model specific embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment one roller shell mechanism cut-away view.
Fig. 2 is a nested structure cut-away view in the utility model embodiment one roller.
Fig. 3 is the utility model embodiment one roller integral installation distribution structure cut-away view.
Fig. 4 is a nested structure cut-away view in the utility model embodiment two rollers.
Embodiment one: hollow roll shell 1 length is 200mm, and external diameter is 200mm, and roller shell one stomidium chamber 4 internal diameters of cover 2 are 160mm in being used to assemble, and vestibule 4 degree of depth are 100mm.Above-mentioned roller shell 1 other end hollow cavity is cone cylinder body shape, and the outer end internal diameter is 165mm, and the thinnest place of internal diameter is 150mm, and its tapering is 1: 15, and whole roller shell adopts high chromium centrifugal cast to form its material selection rich chromium cast iron.Cover 2 adopts plain cast iron in the roller, and its length is 100mm, and its external diameter is 160mm, and the axis hole that is connected with power transmission shaft is cone cylinder body shape, and axis hole 3 maximum gauges are 70mm, and minimum diameter is 60mm, and its tapering is 1: 10.After roller shell 1 and interior cover 2 finished by above-mentioned dimensioned, adopt hot charge practice that interior cover 2 is inlaid in roller shell 1 vestibule and get final product.See structure shown in Figure 3 for details.
Embodiment two: hollow roll shell 1 structure is constant, and just the long size of its roller increases to 360mm, and vestibule 4 degree of depth are 200mm, interior cover 2 basic structures are constant, just increased an annulus sidewall 5 that length is 100mm at the assembling end, assembly method is identical with embodiment one, and interior cover 2 structures see Fig. 4 for details.
