Abstract
The utility model relates to a bearing locking device, which mainly comprises a locking nut, a spiral ring, a fastening bolt, a locking plate, a square key and a clamping ring, wherein the locking nut and the spiral ring are assembled together through a thread; the square key is inserted into the spiral ring and a key slot of a roller neck of a roller, and when the roller rotates, the spiral ring rotates along with the roller; the clamping ring is sleeved in a groove in the end part of the roller; the locking plate is arranged between the locking nut and the spiral ring; the locking nut, the spiral ring and the locking plate are connected by the fastening bolt; and the clamping ring consists of two half rings, one half ring is fixed by a pin shaft and a first connecting plate, and can freely rotate in the first connecting plate, and the other half ring is fixed by a second connecting plate and a screw. The clamping ring is not required to be locked by a special locking tool all the time when being assembled and disassembled; the bearing locking device is rational in structure, and can be assembled and disassembled conveniently and quickly; and in the running process of a rolling mill, the clamping ring cannot fall as long as the screw on the clamping ring is not unscrewed, so that the structural strength is strengthened, the stability is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of locking device, is specifically related to a kind of mechanical bearing locking device.
Background technology
The locking device of filmatic bearing is that the bearing part with filmatic bearing is locked on the roll, to guarantee the normal operation of bearing assembly, and according to the requirement of grinding roller and maintenance, regularly filmatic bearing is disassembled from roll, locking device in use requires handling safety, convenient, fast.In the prior art, bearing locking device mainly is made up of locking nut, volution, fastening bolt, latch, square key, snap ring, and locking nut is by screw thread and volution matched together, square key inserts in the keyway of volution and roller neck, when roll rotation volution is rotated with roll; Snap ring is sleeved in the roll end grooves; described latch is installed between locking nut and the volution, and fastening bolt links together locking nut, volution, latch, wherein on the snap ring seam is arranged; seam is stuck in the volution; this snap ring needs special-purpose locking instrument to pin snap ring when loading and unloading always, when milling train is worked, produces vibrations; snap ring easily comes off; locking nut loses the locking effect, when serious, certainly will cause stopping accident.
The utility model content
The utility model purpose is to provide a kind of rational in infrastructure in order to overcome the deficiencies in the prior art, the bearing locking device of easy installation and removal.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bearing locking device, mainly formed by locking nut, volution, fastening bolt, latch, square key, snap ring, described locking nut is by screw thread and volution matched together, described square key inserts in the keyway of volution and roller neck, when roll rotation volution is rotated with roll; Described snap ring is sleeved in the roll end grooves, and described latch is installed between locking nut and the volution; Described fastening bolt links together locking nut, volution, latch, and described snap ring is made up of two semi-rings, and wherein a semi-ring adopts and fixes with bearing pin, first connecting plate; Described semi-ring can freely rotate in first connecting plate; Wherein another semi-ring is fixed by second connecting plate, screw.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of bearing locking device of the utility model scheme, by the structural design to snap ring, when making the snap ring mounting or dismounting, do not need to lock specially instrument and pin snap ring always, rational in infrastructure, install, convenient disassembly is quick, in the milling train operation process, only otherwise open screw on the snap ring, snap ring can not come off, improve structural strength and stability, prolonged service life.
