Description
Technical Field
The utility model relates to a short stress path rolling mill field specifically indicates a bearing housing seal structure on short stress path rolling mill.
Background
The upper bearing seat is an important part of a short stress path rolling mill, has the effect of lifting, and the pull rod penetrates through the lower through holes at two sides of the pull rod, and the through holes and the smooth cylindrical end of the pull rod need to be provided with a sealing structure so as to ensure that the rolling mill is damaged by invasion of external harmful impurities. The general way of this type of rolling mill at present is that the lower through-hole of directly doing at the bearing goes out the direct processing and goes out the seal groove, and this mode has increased the processing degree of difficulty and the expense of bearing frame, and second sealed effect is relatively poor and not permanent, and in case the seal groove damages the repair difficulty, seriously influences sealed effect, and the inside steady operation that influences the rolling mill of outside dirty debris invasion rolling mill.
Disclosure of Invention
The utility model discloses to prior art's not enough, provide a bearing housing seal structure on short stress path rolling mill that processing is simple, the maintenance is convenient.
The utility model discloses a following technical scheme realizes, provides a bearing housing seal structure on short stress line rolling mill, including bolster bearing housing, it has two vertical lower through-holes to open on the bolster bearing housing, the lower extreme of through-hole is opened down has the heavy platform of cylinder, the detachable seal cover is equipped with in the heavy platform of cylinder, the inner circle top-down of seal cover is equipped with seal groove, well seal groove and lower seal groove in proper order, be equipped with O type circle sealing washer in seal groove and the well seal groove, be equipped with the dust ring in the lower seal groove.
The detachable seal cover is equipped with in the heavy platform of cylinder in this scheme, sets up the operation environment of multichannel sealing in order to strengthen sealed effect in this seal cover, can improve inside spare part better, and seal cover and each sealing member change also very conveniently moreover.
And as optimization, a fastening screw hole is formed in the side surface of the cylindrical sinking platform, and a fastening screw fastened to the outer ring of the sealing sleeve is arranged in the fastening screw hole. Set screw in this scheme is used for the fixed seal cover to realize the dismouting of seal cover.
Preferably, the outer ring of the sealing sleeve is provided with external threads, and the inner hole of the cylindrical sinking platform is provided with internal threads. The seal cover passes through the screw thread and sinks the platform with the cylinder to be connected in this scheme, can be convenient for taking out of seal cover on the one hand, on the other hand plays the restriction effect to seal cover axial direction, prevent because of seal cover from the top down drunkenness lead to with holding screw between the friction not hard up.
As optimization, at least two operation holes are formed in the bottom surface of the sealing sleeve, the operation holes formed in the scheme are used for rotating the sealing sleeve, and the sealing sleeve can rotate only by inserting the tool into the operation holes and rotating the tool.
Preferably, the operation holes are 4 and are uniformly distributed along the circumferential direction. The operating hole is provided with 4 and along circumference equipartition in this scheme, and rotatory frock inserts in two relative operating holes, and rotatory frock is rotatory 90 backs, inserts rotatory frock other two operations aloft to be convenient for at narrow and small space rotary seal cover.
Preferably, the lower sealing groove is formed in the lower end of the sealing sleeve. Lower seal groove in this scheme sets up the lower extreme at the seal cover to play dustproof effect to the lowermost end of seal cover.
The beneficial effects of the utility model are that: the utility model discloses a bearing frame seal structure on short stress line rolling mill sets up the seal cover that can the dismouting through the lower through-hole bottom in bearing frame both sides on the rolling mill to set up multichannel seal structure on the seal cover, thereby not only strengthened sealed effect, reduced the preparation degree of difficulty of bearing frame moreover, seal cover and sealing member are changed also conveniently, and the maintenance degree of difficulty reduces, is favorable to the stable performance of short stress line rolling mill performance.
