Abstract
The utility model discloses an improved inner geared sleeve for a hot rolling transmission shaft, which belongs to the technical field of rolling mill equipment and is used for making the inner geared sleeve more wear-resistant and convenient to maintain. According to a technical scheme, two opposite inner surfaces of an inner geared sleeve cavity at the output end of a main transmission toothed shaft of a rolling machine are provided with two symmetrical planar grooves; two groove planes are parallel to each other; the areas of the groove planes are matched with the assembly area of a roller flat head; replaceable wear-resistant lining plates are arranged on the grooves; and the distance between opposite inner surfaces of the replaceable wear-resistant lining plates is matched with the assembly thickness of the roller flat head. In the inner geared sleeve, a worn replaceable wear-resistant lining plate can be replaced in time, so that the replacement of the entire inner geared sleeve and the excessive repair of other parts are avoided, time and labor are saved, the spare part cost and the labor cost are saved greatly, the intensive vibration of the rolling mill caused by the late replacement of the transmission shaft is avoided, and the product quality and successful performance of production are ensured.
Description
Technical field
The utility model relates to a kind of power transmission shaft internal tooth casing of continuous hot-rolling mill, belongs to the milling equipment technical field.
Background technology
In the transmission system of the thick finishing mill of continuous casting and rolling factory, gear pedestal and working roll are to be rigidly connected, and power is given working roll by the flute profile power transmission shaft from the transmission of gear pedestal, and transmission cooperates closely.Find that in actual production there are the bigger problem of fit clearance in existing power transmission shaft fore side internal tooth casing and roll homalocephalus, make oil storage tank excessive, water inlet and iron scale cause serious wear easily.Simultaneously, because roll homalocephalus and axle sleeve fit clearance are excessive, the normal specifications that influences milling train is rolling, makes milling train vibrations aggravation, and the rate of wear speeds.According to the on-site maintenance experience, major part all is that the internal tooth casing wearing and tearing are more serious, and other parts do not need to change.And the internal tooth casing spare part order cycle time is long, and the spare part expense is high, and the replacing of all power transmission shafts all need shut down more than 8 hours and just can carry out, and not only loses time, and also makes equipment be in the state of excessive maintenance, has influenced carrying out smoothly of producing.In view of this, be necessary the internal tooth casing of milling train flute profile power transmission shaft is reasonably transformed, with improve internal tooth casing the machine life-span with shorten maintenance time, reduce the cost pressure that spare part is repaired.
The utility model content
The utility model technical problem to be solved provides a kind of improved hot rolling power transmission shaft internal tooth casing of being convenient to dismantle and change abrasion-proof backing block.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved hot rolling power transmission shaft internal tooth casing; Its improvements are; On the opposite inner face of the output internal tooth casing cavity of milling train main transmission toothed shank, have the plane groove of two symmetries, two groove plane parallel, the assembling area of the area on groove plane and roll homalocephalus is complementary; On two grooves, replaceable abrasion-proof backing block is installed, the distance of two replaceable abrasion-proof backing block interior surface opposing is complementary with the assembling thickness of roll homalocephalus.
Above-mentioned improved hot rolling power transmission shaft internal tooth casing, the plane groove of described replaceable abrasion-proof backing block and internal tooth casing inner surface is fixed by set bolt.
Above-mentioned improved hot rolling power transmission shaft internal tooth casing, there is chamfering at the two ends up and down on the plane that described replaceable abrasion-proof backing block is relative with the internal tooth casing inner surface, and replaceable abrasion-proof backing block has oil groove on the plane relative with the roll homalocephalus.
Adopt the hot rolling power transmission shaft internal tooth casing of this structure; At the surface of internal cavity of internal tooth casing replaceable abrasion-proof backing block has been installed; Can in time change when wearing and tearing take place for replaceable abrasion-proof backing block, avoid the integral body of internal tooth casing is changed and to the excessive maintenance of other parts, time saving and energy saving; The replacing time can shorten to 1/10 of the former time; And practiced thrift spare part expense and labour cost greatly, more avoided, guaranteed that product quality carries out with producing smoothly because power transmission shaft is changed the untimely milling train vibrations aggravation that causes.
