Abstract
A universal coupling device for a rolling mill comprises a splined shaft, a splined hub, a rolling-mill-end external gear shaft sleeve, a rolling-mill-end internal gear sleeve, a rolling-mill-end external gear sleeve, a drum type ball, internal ball-shaped copper rings, a reducer-section internal gear sleeve, a gland and the like. The universal coupling device adopts the design scheme as follows: one internal ball-shaped copper ring is mounted in the rolling-mill-end internal gear sleeve and the gland and matched with the spherical surface of the rolling-mill-end external gear sleeve, and the other internal ball-shaped copper ring is mounted in the reducer-section internal gear sleeve and the gland and matched with the spherical surface of the reducer-section internal gear sleeve. The universal coupling device for the rolling mill has the advantages as follows: a universal coupling is stable in axial positioning and does not play, the movement stability of the device is greatly superior to a cross axle universal coupling and a crown gear universal coupling, vibration of the rolling mill can be reduced after a balance trunnion seat is connected with a rolling mill bracket, the rolling speed is increased, the rolling mill operates stably, and the universal coupling device is suitable for being used in production lines of a high-speed wire rolling mill and a bar mill.

Technical field
The present invention relates to a kind of milling train universal joint shaft apparatus, belong to technical field of steel rolling.
Background technique
Chinese patent notice of authorization CN2266054Y, application number 96221510.4, name is called ball universal coupling, a kind of ball universal coupling is disclosed, this model utility is for solving the problem that universal coupling with spider is fragile, the life-span is low, at the internal surface of internal tooth casing and the outer surface of half-coupling, along circumference, have the half-cylindrical straight trough of corresponding decile, in each straight trough, have steel ball.Its steel ball bearing capacity is low, the life-span is low, due to without axial direction positioning device, without middle, without spline pair, can not be applicable to fast roll changing and milling train is traversing.In addition, owing to there is no Hooks coupling universal coupling Equilibrator, when milling train runs up, milling train, Hooks coupling universal coupling and bracket serious vibration, thus cause the serious accidents such as bracket and roller-mill bearing scaling loss, also cause the damage of the spare parts such as Hooks coupling universal coupling, bearing.Chinese patent notice of authorization CN2921433Y, application number 200620105734.7, name is called spherical roller coupler, a kind of spherical roller coupler is disclosed, this model utility is by ring gear, external toothing, spherical roller, back-up ring, end casing, sealing ring fixed plate and seal ring form, wherein spherical roller is similar to waist drum, its bus is circular arc line, this spherical roller coupler is provided with axially locating parts, but this model utility axially locating part complex structure, rate of fault is higher, be not suitable for using on steel rolling equipment, therefore, be necessary Hooks coupling universal coupling to improve.
Summary of the invention
Milling train and bracket serious vibration when the object of the invention is to overcome existing milling train and running up, Hooks coupling universal coupling axially locating is poor, complex structure, problem that rate of fault is higher, and a kind of milling train universal joint shaft apparatus is provided.The technical solution adopted in the present invention is: a kind of milling train universal joint shaft apparatus, is comprised of splined shaft, spline housing, milling train end external tooth cover, milling train end internal tooth casing, cydariform ball, interior spherical copper ring, speed reducer end internal tooth casing, gland, ball baffle plate, speed reducer end external tooth cover, seal ring, balance trunnion base, bearing, bearing baffle.Interior spherical copper ring is arranged in milling train end internal tooth casing and gland, interior spherical copper ring is arranged in speed reducer end internal tooth casing and gland, interior spherical copper ring coordinates with the sphere of milling train end external tooth cover, interior spherical copper ring coordinates with the sphere of speed reducer end external tooth cover, splined shaft and milling train end external tooth cover interference fit, ball baffle plate is welded on milling train end external tooth cover, ball baffle plate is welded on speed reducer end external tooth cover, cydariform ball is arranged in the groove of milling train end external tooth cover and milling train end internal tooth casing, and cydariform ball is arranged in the groove of speed reducer end external tooth cover and speed reducer end internal tooth casing.Spline housing and speed reducer end external tooth cover are welded together.Bearing baffle, balance trunnion base, bearing are arranged on splined shaft.
The present invention has the following advantages: designed Hooks coupling universal coupling Equilibrator, Hooks coupling universal coupling axially locating is stable, play, its robust motion will not be better than universal coupling with spider and crowned teeth Hooks coupling universal coupling greatly, and reasonably structure has met high speed, high-precision transmission requirement.Milling train smooth running is suitablely used in high-speed wire mill, bar mill production line.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment, as shown in Figure 2, a milling train universal joint shaft apparatus, is comprised of splined shaft 1, spline housing 2, milling train end external tooth cover 3, milling train end internal tooth casing 4, cydariform ball 5, interior spherical copper ring 6, speed reducer end internal tooth casing 7, gland 8, ball baffle plate 9, speed reducer end external tooth cover 10, seal ring 11, balance trunnion base 12, bearing 13, bearing baffle 14.Interior spherical copper ring 6 is arranged in milling train end internal tooth casing 4 and gland 8, interior spherical copper ring 6 is arranged in speed reducer end internal tooth casing 7 and gland 8, interior spherical copper ring 6 coordinates with the sphere of milling train end external tooth cover 3, interior spherical copper ring 6 coordinates with the sphere of speed reducer end external tooth cover 10, splined shaft 1 and milling train end external tooth cover 3 interference fit, ball baffle plate 9 is welded on milling train end external tooth cover 3, and ball baffle plate 9 is welded on speed reducer end external tooth cover 10.Cydariform ball 5 is arranged in the groove of milling train end external tooth cover 3 and milling train end internal tooth casing 4, and cydariform ball 5 is arranged in the groove of speed reducer end external tooth cover 10 and speed reducer end internal tooth casing 7.Spline housing 2 is welded together with speed reducer end external tooth cover 10, and the position of the cooperation place of spline pair keeps in spline housing always.Bearing baffle 14, balance trunnion base 12, bearing 13 are arranged on splined shaft 1, and balance trunnion base 12 can reduce rolling mill vibration after connecting with milling train bracket.Because milling train end external tooth cover is accurately positioned in milling train end internal tooth casing by two interior spherical copper rings, speed reducer end external tooth cover is accurately positioned in speed reducer end internal tooth casing by two interior spherical copper rings, and centering has well reduced Hooks coupling universal coupling gap and shifting amount.
