Description
Technical field
This utility model belongs to roll squeezer technical field, particularly relates to a kind of roll squeezer detachable sliding key asembly.
Background technology
Roll squeezer is equipped as the main frame of cement production enterprise grinding system, and the use of its engineering reliability pair roller press apparatus plays vital effect.Roll squeezer is mainly made up of the part such as two main motors, two planet-gear speed reducers, roller, roller supporting, frame, moment of torsion supporting, hydraulic pulldown, lubricating arrangement, drawing-in device, jacket, control systems.In operation process, two roll shafts need to drive respectively, and dancer drives the reciprocal transverse shifting of roll support.Therefore have feather key structure in roll squeezer dancer bearing block bottom design, in the motor process of roller supporting, play guiding and the effect of transmission axial force.This feather key, as the consumable accessory of roll squeezer operating key position, can produce heavy wear and its internal as easy as rolling off a log damage of oscillating bearing in the process that long-term roll-in is pulverized, and maintenance time is longer, reduces the running rate of roll squeezer.
At present, the feather key structure used both at home and abroad, how in bearing block internal COStS hole, after coordinating with bearing pin, bearing pin coordinates with feather key again, and feather key is typically designed as metal feather key structure, coating lubricating oil when it is installed, but abrasion is also very fast.After feather key abrasion, in Renewal process, it is necessary to dismounting roll squeezer upper spider, by bearing block two ends jack-up simultaneously, feather key can be replaced, waste time and energy.
Summary of the invention
This utility model provide for solving the technical problem that exists in known technology a kind of simple in construction, easy to install, be easier to change, the roll squeezer detachable sliding key asembly of long service life.
This utility model is adopted the technical scheme that by the technical problem solving to exist in known technology:
A kind of roll squeezer detachable sliding key asembly, detachable sliding key asembly is arranged on the upper and lower of roll squeezer floating end roller axle bearing, it is characterized in that: be equipped with mounting groove in the upper and lower of roller axle bearing, in mounting groove, by securing member, detachable sliding key asembly is installed；Described detachable sliding key asembly includes dismounting block, bearing pin and feather key, wherein said dismounting block includes the connection base mated with the mounting groove in roller axle bearing, described connection base is provided with installing hole, the outside connecting base is provided with mounting seat, described mounting seat is provided with pin shaft hole, one end of interference fit bearing pin in pin shaft hole, the other end projecting pin axis hole of bearing pin, on the bearing pin stretched out, matched in clearance installs feather key.
This utility model can also adopt following technical measures:
The upper and lower surface of described feather key is two rubbing surfaces, is equipped with groove, is embedded with PTFE anti-wear plate by securing member in groove on two rubbing surfaces.
Described feather key is provided with oilhole along its length.
This utility model has the advantage that and has the benefit effect that owing to this utility model adopts technique scheme, compares with existing feather key structure and has the advantage that 1, feather key adopts demountable structure, and technique is simple, and maintenance cost is low, and equipment operation efficiency is high；2, removable oblique feather key is bolted, and installation and removal are convenient, and maintenance cost is low；3, feather key both ends rubbing surface is inlaid with polyfluortetraethylene plate, can reduce the abrasion of feather key, improves equipment operation efficiency.
