Abstract
The utility model belongs to an improvement of a flat-head lining board structure of a cardan shaft of a roughing mill of a steel-rolling hot rolled plate plant, in particular to the flat-head lining board structure of the cardan shaft of the hot rolled plate roughing mill. The flat-head lining board structure comprises a flat-head lining board mounted in a step hole of a flat-head sleeve of the cardan shaft; the flat-head lining board is composed of an inner lining board and an outer lining board which are matched with each other, thereby forming a composite step lining board; a convex strip, of which the surface is a circular arc face, is arranged on the outer surface of the inner lining board along the axis of the flat-head sleeve; the convex strip is matched with a groove provided with a circular arc bottom face and arranged on the wall of the step hole of the flat-head sleeve; an rectangular convex strip is arranged on the inner surface of the inner lining board along the axis of the flat-head sleeve; a groove matched with the rectangular convex strip of the inner lining board is formed on the surface of the outer lining board, where the outer lining board and the inner lining board are matched; and chamfers of 45 degrees are respectively arranged at plate corners of the inner and the outer lining boards matched with the step hole of the flat-head sleeve. The flat-head lining board structure can increase the strength of the flat-head sleeve, reduce stress concentration, reduce abrasion of the lining boards, improve the bearing strength, prolong the service life of the cardan shaft, and guarantee the normal production of rolled steel.
Description
Technical field
The utility model belongs to the improvement of steel rolling hot rolled plate factory roughing mill universal drive shaft homalocephalus lining plate structure, particularly hot rolled plate roughing mill universal drive shaft homalocephalus lining plate structure.
Background technology
The roughing mill that uses in steel rolling hot rolled plate factory, the a pair of square liner plate of the many employings of universal drive shaft homalocephalus lining plate structure relatively more commonly used at present, for overlapping the drift angle place with homalocephalus, installation square liner plate leaves darker groove, thereby influence homalocephalus cover torsional strength, the upper and lower universal drive shaft of hot rolling roughing mill in use between four drift angle places, not long homalocephalus hole elongated crackle takes place, and constantly extend subsequently, adding liner plate plane and side excessive wear causes two universal drive shafts to lose efficacy in advance, cause the tremendous economic loss, and influence the steel rolling ordinary production.
Summary of the invention
The purpose of this utility model is to provide a kind of hot rolled plate roughing mill universal drive shaft homalocephalus lining plate structure, can increase the intensity of homalocephalus cover, reduces stress and concentrates, reduce the wearing and tearing of liner plate, improve bearing strength, prolong the service life of universal drive shaft, guarantee the steel rolling ordinary production.
The purpose of this utility model is achieved in that a kind of hot rolled plate roughing mill universal drive shaft homalocephalus lining plate structure, comprise the homalocephalus liner plate that is installed in the universal drive shaft homalocephalus cover shoulder hole, the homalocephalus liner plate is cooperatively interacted by interior lining panel and outer liner plate and constitutes the composite step liner plate, wherein the surface is being set and is being the raised line of arc surface at the outer surface upper edge of interior lining panel homalocephalus cover axis, on raised line and the homalocephalus cover ladder hole wall groove with circular-arc bottom face being set matches, the inner surface upper edge homalocephalus cover axis of interior lining panel is being provided with the rectangle raised line, on the outer liner plate surface that liner plate matches with interior lining panel the groove that matches with interior lining panel rectangle raised line is being set outside, in matching with homalocephalus cover shoulder hole, the place, plate angle of outer liner plate is being provided with 45 ° chamfering respectively.
Structure of the present utility model makes homalocephalus overlap stressed critical section size and becomes big, has improved bearing strength.Being cooperatively interacted by interior lining panel and outer liner plate constitutes the composite step liner plate, and circular arc raised line and rectangle raised line are being set respectively on the surfaces externally and internally of interior lining panel, and overlaps groove on the hole wall with homalocephalus respectively and the groove on the outer lining face matches.When liner plate driving roll turns clockwise outside the driven by motor universal drive shaft, stressed will bearing by interior lining panel upper surface, rectangular recess face and the dispersion of homalocephalus slotted eye side, outer liner plate upper surface of while bears outer liner plate pressure, bears the active force of homalocephalus slotted eye, disperseed stressedly like this, reduced the wearing and tearing of outer liner plate and interior lining panel and homalocephalus slotted eye.Be combined into ladder lining board by inside and outside liner plate, can be separated into each other the power of offsetting by interior lining panel after making outer liner plate stressed, make homalocephalus overlap stressed dispersion.Originally be the rectangle liner plate to be installed homalocephalus is overlapped the drift angle place leave darker groove, reduced the torsional strength of homalocephalus cover.The utility model constitutes ladder lining board by inside and outside liner plate, makes original big turning change the little turning of two steps into, has reduced the wearing and tearing of liner plate.The utility model has increased the intensity of homalocephalus cover, has reduced stress and has concentrated, and has reduced the wearing and tearing of liner plate, has improved bearing strength, has prolonged the service life of universal drive shaft, has guaranteed the steel rolling ordinary production.
