Description
Technical Field
The utility model relates to a belted steel rolling equipment field specifically indicates a make things convenient for backing roll external screw thread locking cover structure of dismouting.
Background
In many strip steel production enterprises, the four-high mill has wide application and plays a role in lifting, the supporting roll is used as one of core components for bearing rolling force, the working condition is complex, the radial load and the axial load are borne and respectively acted on the cylindrical roller bearing and the thrust bearing, and the assembly quality of the two components plays a crucial role in the assembly of the whole supporting roll.
And in the component parts of the supporting roller assembly, the internal and external thread locking device is an important ring for installing and fixing the bearing inner ring. During assembly, the inner ring of the bearing is tightly locked by adjusting the screwing length of the threads of the two; during disassembly, the screwing length of the two threads is firstly adjusted to be separated from contacting other parts, so that an opportunity is provided for disassembling other parts.
Because there is not radial location structure in current external screw thread cover hole and backing roll roller, when stirring the internal thread cover and adjusting the screw thread and closing the length soon, very easily can appear the external screw thread cover along with the problem of internal thread cover together pivoted, cause whole dismantlement or assembly work to waste time and energy.
Disclosure of Invention
The utility model discloses to prior art's not enough, provide a make things convenient for supporting roller external screw thread locking cover structure of dismouting.
The utility model discloses a through following technical scheme realizes, provide a make things convenient for supporting roller external screw thread lock sleeve structure of dismouting, including supporting roller and the cover at the epaxial lock sleeve of supporting roller, the outer lane of lock sleeve is provided with the external screw thread, the rigid coupling has the guide block on the periphery of supporting roller, and the hole of lock sleeve is provided with the guide way that extends along supporting roller length direction.
In the scheme, the outer thread locking sleeve is sleeved on the supporting roller shaft, and after the guide groove of the outer thread locking sleeve is matched with the corresponding guide block on the supporting roller shaft, the outer thread locking sleeve can only slide along the axis and cannot rotate, so that when the inner thread sleeve screwed with the outer thread locking sleeve is rotated, the inner thread locking sleeve and the outer thread locking sleeve can be rapidly and continuously adjusted to be screwed to achieve the smooth dismounting and mounting work of the supporting roller shaft, and the working efficiency and the assembling quality are improved.
Preferably, the guide block is a guide key, and the guide groove is a guide key groove. The guide block is the guide key in this scheme, the guide way is the direction keyway to the processing setting of the guide block of being convenient for and guide way, and the slip of guide key and direction keyway is level and smooth.
Preferably, the locking sleeve comprises a positioning sleeve and a threaded sleeve which are axially arranged along the supporting roller shaft and are integrally formed, the external thread is arranged on the threaded sleeve, the outer diameter of the positioning sleeve is larger than that of the threaded sleeve, and a connecting positioning hole parallel to the central shaft of the positioning sleeve is formed in the positioning sleeve. In the scheme, the external thread is arranged on the thread sleeve, the positioning sleeve is provided with a connecting positioning hole parallel to the central axis of the positioning sleeve, and the connecting hole on the positioning sleeve is connected with the connecting hole on the internal thread sleeve through a bolt, so that the positioning connection between the locking sleeve and the internal thread sleeve is realized.
Preferably, the number of the connecting positioning holes is 4, and the connecting positioning holes are uniformly distributed along the circumferential direction of the central shaft of the positioning sleeve. The connecting location hole is provided with 4 and along position sleeve center pin circumference equipartition in this scheme, makes the location even.
Preferably, the length of the positioning sleeve is smaller than that of the threaded sleeve. The length of position sleeve in this scheme is less than the length of thread bush to the length of increase screw thread reduces the length of position sleeve, reduce cost.
As optimization, the guide way runs through the lock sleeve along the length direction of the supporting roller shaft, and the guide way runs through the lock sleeve along the length direction of the supporting roller shaft in the scheme, so that the positioning block can be conveniently inserted into the positioning groove.
The utility model has the advantages that: the utility model discloses a make things convenient for supporting roller external screw thread locking cover structure of dismouting, guide block cooperation back that corresponds on guide way through the lock sleeve inner circle and the supporting roller makes the external screw thread lock sleeve can only slide and unable rotation along the axis, like this, when rotating the internal thread cover that closes soon with it, thereby just can adjust the interior external screw thread fast and close the dismouting work of length smooth completion supporting roller soon, improved work efficiency and assembly quality.
