Abstract
The utility model discloses a vice protection casing of split type spline, it includes gland, screw, it still includes flange joint cover, flange seal cover, the flange and the flange seal of flange joint cover right -hand member cover and are connected through the fastener between the flange of left end, the left end of flange seal cover overlaps on the integral key shaft and installs the sealing washer, through screw and gland connection, the right -hand member of flange joint cover overlaps on the spline housing and installs the sealing washer. It can disassemble the separation at the use scene the vice protection casing of this novel spline, is convenient for observe the wearing and tearing circumstances of the vice inside lubricated circumstances of spline, measuring integral key shaft, realizes the whole control to the vice in service behavior of spline, avoids spline pair position " in spite of illness " work to appear, guarantees the output and the quality of generous board production line.
Description
Technical field
The utility model relates to Wide and Thick Slab roughing mills main transmission universal-joint spindle and to stretch the protective housing of spline pair.
Background technique
In recent years, World Iron & Steel, in existing Wide and Thick Slab steel rolling technology, in order to reduce the wearing and tearing of work roll, obtains better plate shape, and generally use roll shifting technology, this just requires that Wide and Thick Slab roughing mills main transmission universal-joint spindle must be able to stretch.Existing Telescopic is all realized by spline, because Wide and Thick Slab rolls roughing main transmission cardan shaft operation torque greatly, rotating speed is high, especially in steel rolling occlusion moment, impact comparatively large, be therefore with the stretch service condition of spline of universal-joint spindle of spline directly to affect the seed output and quality of Heavy Plate Rolling Line.
In the flexible spline pair structure of existing Wide and Thick Slab roughing main transmission universal-joint spindle, spline pair position adopts dry oil lubrication, splined shaft and spline housing can realize relative movement by spline, during spline pair flex, protective housing and splined shaft are fixed, can relative movement with spline housing, the moving surface of protective housing and spline housing is sealed by seal ring, ensures that lubricating grease can not leak.Because existing protective housing is all overall structure, the lubrication circumstances of spline pair inside cannot be observed in spindle using process, therefore cannot detect the abrasion condition of splined shaft, inconvenience and field maintenance are maintained, thus cannot ensure the seed output and quality of Heavy Plate Rolling Line.
Model utility content
Problem to be solved in the utility model is to provide a kind of split type spline pair protective housing, it can disassemble separation at use scene, be convenient to observe the lubrication circumstances of spline pair inside, detect the abrasion condition of splined shaft, realize the complete monitoring to spline pair service condition, avoid spline pair position to occur " in spite of illness " work, guarantee the seed output and quality of Heavy Plate Rolling Line.
A kind of split type spline pair protective housing of the utility model, it comprises gland, screw, and it also comprises Flange joint cover, flange seal cover; The flange of Flange joint cover right-hand member is connected by fastening piece with between the flange of flange seal cover left end; The left end of flange seal cover to be enclosed within splined shaft and to install seal ring, is connected with gland by screw; The right-hand member of Flange joint cover to be enclosed within spline housing and to install seal ring.
Flange joint cover in the utility model protective housing is connected by fastening piece with flange seal cover, when spline pair inner case observed by needs, fastening piece is only needed to pull down, Flange joint cover is separated with flange seal cover, just can be observed the lubrication circumstances of spline pair inside, detect the abrasion condition of splined shaft, realize the complete monitoring to spline pair service condition, avoid spline pair position to occur " in spite of illness " work, guarantee the seed output and quality of Heavy Plate Rolling Line.
The utility model protective housing is disassembled at use scene and is separated and returns dress more for convenience, and the field maintenance time is short, meets onsite application requirement.
Accompanying drawing explanation
Fig. 1 is the spline pair protective housing schematic diagram of this New type detachable;
Fig. 2 is the enlarged diagram at X place in Fig. 1.
Embodiment
From Fig. 1, Fig. 2, a kind of split type spline pair protective housing of the utility model, it comprises gland 2, screw 3, and it also comprises Flange joint cover 4, flange seal cover 6; Be connected by fastening piece 5 between the flange of Flange joint cover 4 right-hand member and the flange of flange seal cover 6 left end; The left end of flange seal cover 4 to be enclosed within splined shaft 1 and to install seal ring, is connected with gland 2 by screw 3; The right-hand member of Flange joint cover 6 to be enclosed within spline housing 7 and to install seal ring.
As a kind of improved procedure that this is novel, undertaken coordinating by convex-concave seam between the right-hand member of Flange joint cover 4 and the left end of flange seal cover 6 and locate.Flange joint cover and flange seal cover adopt convex-concave seam to coordinate, and make can locate easily between the two, also can play better seal action simultaneously,
As a kind of optimal way that this is novel, gland 2 is split type structure, is arranged in the draw-in groove 8 of splined shaft 1.Like this, protective housing can be made to take off easily.
The spline pair protective housing of this New type detachable achieves easily and is using on-the-spot disassembling be separated and return the function course filled: use on-the-spot in spindle, fastening piece 5 between Flange joint cover 4 and flange seal cover 6 can be dismantled, flange seal cover 6 moves to spline housing 7 direction, the gland 2 of split type structure can be dismantled simultaneously, Flange joint cover 4 moves to the opposite direction of spline housing 7, thus the lubrication circumstances of spline pair inside can be observed, detect the abrasion condition of splined shaft, realize the complete monitoring to spline pair service condition, spline pair position is avoided to occur " in spite of illness " work, guarantee the seed output and quality of Heavy Plate Rolling Line, and meet the requirement of cardan shaft spline pair operation of rolling continuous operation.
The utility model device is not limited to and is used in Wide and Thick Slab roughing mills main transmission universal-joint spindle and stretches on spline pair, also can be widely used on the protective housing of other flexible spline pair.
