Abstract

The utility model provides a filmatic bearing with a quick locking device, comprising a taper sleeve or a column sleeve, a lining, a bearing seat, a roller bearing box, a roller bearing, an end cover cap and a sealing device. The utility model is characterized in that the quick locking device is composed of a bolt ring, nuts, a fastening bolt, a screw hole on the end face of the nut, a square locking block, a rectangular tank, a plane surface matching with the locking block, etc. The locking device has simple structure and manufacture, low manufacture cost, quick installation and reliable operation. The utility model can avoid the accidents of the damage of the whole filmatic bearing and production halts, caused by the locking device. The utility model can be used for various mills and other heavy equipment.

Description

A kind of filmatic bearing with quick-locking device

The utility model belongs to filmatic bearing, particularly is applied to a kind of filmatic bearing that has quick-locking device in the rolling equipment.

Be used for the backing roll of hot-rolled and cold-rolled band mill or the filmatic bearing technology on the working roll now, mainly comprise the tapered sleeve or the cylindrical sleeve that are installed on the roller neck, and lining that cooperate with tapered sleeve, relative motion, bearing block, the roller bearing case, the tapered sleeve ring of location tapered sleeve, roller bearing locking device, the end shield that are connected on the bearing block cover, and film bearing seal device etc.Described locking device reaches screw on nut end face by bolt ring, nut, fastening bolt, and fan-shaped latch segment etc. consist of fan-shaped locking device.Particularly in large-sized rolling mills used, because coupling mechanism force leans on the hole on the clamping screw ring to adjust, and locked position was few, and the secter pat heaviness, very inconvenience of installing/dismounting, the degree of regulation of axial locking is also lower.Simultaneously, precision prescribed height in the mill, manufacture difficulty is bigger, is in operation to cause axial motion, often makes filmatic bearing roller footpath bad seals, and causes into water leakage of oil, even take place that secter pat is loosening to fall down, and causes economic losses such as whole production line stopping production.

In addition, also have a kind of plum blossom lobe shape locking device, its locking key, volution are installed on the roll, and need process plum blossom lobe shape on roll, and difficulty of processing is bigger, the cost height.

The purpose of this utility model provides a kind of Fast Installation that has, and structure and manufacturing are simple, low cost of manufacture are installed, the filmatic bearing of reliable locking device.

A kind of filmatic bearing that has quick-locking device provided by the utility model, it comprises tapered sleeve or the cylindrical sleeve that is installed on the roll neck, and cooperate with tapered sleeve, lining in relative rotation, the bearing block of mounting bush, be connected roller bearing case on the bearing block, be installed on the roll neck and locate the tapered sleeve ring of tapered sleeve, roller bearing, the locking device of the roller bearing on the roll neck and end shield lid, sealing device etc. between roll and the filmatic bearing, described locking device by bolt ring, nut, fastening bolt and on nut end face screw, latch segment is formed; Its characteristics are: a square latch segment is installed on the nut of described locking device at least, is provided with at least four planes of matching with latch segment in the termination of described bolt ring, fastening bolt is installed in latch segment on bolt plane of a loop and the nut end face.

By adopting the utility model that a kind of filmatic bearing with quick-locking device is provided.Its structure and manufacturing are simple, low cost of manufacture is installed, but Fast Installation are reliable.Avoid taking place to make the damage of whole filmatic bearing, avoid the stopping production accident of rolling line simultaneously, reduced production cost, have tangible economic benefit because of locking device.But among the various milling trains of extensive use and other jumbo.

Description of drawings:

Fig. 1 is a kind of filmatic bearing structural representation with quick-locking device;

Fig. 2 is the quick-locking device structure enlarged drawing of filmatic bearing;

Fig. 3 is the quick-locking device end view of filmatic bearing.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1, Fig. 2 and Fig. 3.A kind of filmatic bearing with quick-locking device comprises tapered sleeve or the cylindrical sleeve 2 that is installed on the roll neck 1, and cooperate with tapered sleeve, lining 3 in relative rotation, the bearing block 4 of mounting bush, be connected roller bearing case 5 on the bearing block, be installed on the roll neck and locate the tapered sleeve ring 6 of tapered sleeve, roller bearing 7, the locking device 8 of the roller bearing on the roll neck and end shield lid 9, sealing device 10 etc. between roll and the filmatic bearing, described locking device reaches screw 14 on nut end face by bolt ring 11, nut 12, fastening bolt 13, and latch segment 15 is formed; Four square latch segments are installed on the nut of described locking device, and on the end face of nut, are provided with four rectangular channels 17 that cooperate with square latch segment, be provided with nine planes 16 of matching with latch segment in the termination of described bolt ring.When the locking device of filmatic bearing is installed, because nut is provided with four latch segments, and nine planes that are used to lock are arranged on the bolt ring, in adjusting the nut degree of tightness, have 4 * 9=36 position like this, it is very high to adjust precision.Wherein said four square latch segments and nine locking faces are only used a square latch segment and locking face when locking.On the fastening bolt after the locking, two bolt penetration hole are connected, reinforce and lock and prevent to become flexible with iron wire.
