Hydraulic rapid locking device for oil film bearing

Abstract

The invention relates to a hydraulic rapid locking device for an oil film bearing. The locking device comprises a short pattern hydraulic cylinder, a locking plate, a square key, a snap ring assembly etc., wherein the short pattern hydraulic cylinder comprises a cylinder sleeve, a piston, a cylinder cover, a nut, a sealing and a quick-change joint, etc. The locking device is characterized by changing a machinery locking into a hydraulic locking, wherein an original roller structure is maintained, and the machinery locking is changed into the hydraulic locking by utilizing present space; and a locking nut and a volution are omitted to change into a short pattern hydraulic cylinder structure. While loading and unloading of the oil film bearing, the quick-change joint on a hydraulic tool is connected to the short pattern hydraulic cylinder to start the hydraulic tool; pressure oil enters into a locking oil pocket or a dismounting oil pocket; and a locking pressure and a dismounting pressure are controlled quantificationally to complete bearing locking or dismounting. The locking device has effects of convenient loading and unloading, accurate quantification, rapidness and safety.

Description

technical field [0001] The invention relates to an oil film bearing, in particular to a hydraulic locking device for the oil film bearing. Background technique [0002] The locking device of the oil film bearing is to lock the bearing part of the oil film bearing on the roll to ensure the normal operation of the bearing assembly, and periodically disassemble the oil film bearing from the roll according to the requirements of grinding roll and maintenance. The locking device requires safe, convenient and fast operation during use. [0003] Such as figure 1 As shown, the existing locking device is a mechanical locking structure, which is mainly composed of a lock nut 1, a spiral ring 2, a fastening bolt 3, a locking plate 4, a square key 5, and a snap ring assembly 6. The lock nut 1 passes through The screw thread and the spiral ring 2 are assembled together, the square key 5 is installed in the keyway 7-1 of the roll 7 and embedded in the inner hole groove of the spiral rin...

AI Technical Summary

Problems solved by technology

Its shortcomings and shortcomings are: the locking force cannot be quantitatively controlled, and it can only be judged by the work experience of the workers, so that the oil film bearing is locked on the roll, the locking and disassembly operations are complicated, and it takes a long time for the bridge crane to assemble and disassemble. Human experience is required to judge, and there are potential safety hazards
