Description
Affiliated technical field
The utility model relates to the novel dirt middle (center) bearing of a kind of electric cleaner.
Background technology
At present, known electric cleaner dirt middle (center) bearing adopts guard shield and the conjuncted version of bearing more, and the guard shield open top hangs installation, opening part backing pin shutoff for rapping shaft; Support roller is a cylinder, internal diameter and supporting-roller shaft matched in clearance, and be installed in by supporting-roller shaft in the axis hole of bearing both sides wallboard, wallboard outside axle head is fixed with pad and split pin.In view of the dirt middle (center) bearing is in high-pressure electrostatic, high dense dust, the particular surroundings discontinuous work of high-temperature flue gas very easily takes place too much to cause stall because of dust gathers between support roller and the supporting-roller shaft, thereby makes the rolling friction inefficacy between support roller and the rapping shaft become sliding friction.Like this, parts wear aggravation on the one hand, the rapping shaft rotary load increases on the other hand, if analogue appears in a plurality of dirt middle (center) bearings simultaneously, the magnetic axis of then isolating the electric field transferring power will burst apart because of load is overweight, cause the forfeiture of this electric field dust collection capacity.In addition, field maintenance behind the dirt middle (center) bearing stall is difficulty, the dust intensity of condensing is very big, supporting-roller shaft is difficult for separating with support roller, normal conditions are with dirt middle (center) bearing integral replacing, but change the dirt middle (center) bearing and height must be removed in advance and hung to rapping shaft again, also the general locking technologies of spot welding that adopt of rapping parts bolt more, and therefore whole replacing process is time-consuming quite loaded down with trivial details.
Summary of the invention
In order to solve existing electric cleaner dirt middle (center) bearing because the inconvenience that reasons in structure is brought to O﹠M, the utility model provides a kind of guard shield and bearing separable, band sealing shroud between support roller and the supporting-roller shaft, the parts that supporting-roller shaft and support roller etc. are formed can be relaxedly and rapidly with the bearing installation and removal, can effectively enhance product performance, installation, maintenance, change all the novel dirt middle (center) bearing of electric cleaner very easily.
The utility model is achieved in that support roller parts that it is made of supporting-roller shaft, support roller, sealing shroud and bearing, pad, locking cover, split pin, bearing pin, back-up ring, guard shield etc. form.Supporting-roller shaft, support roller are cylindric, matched in clearance, and sealing shroud is established at two ends; One section narrow road is established at supporting-roller shaft middle part, and suitably reducing the contact area between support roller, two ends are provided with circlip groove and cotter-pin hold.Base-plate is rectangle, and there is the fixedly bolt hole of usefulness at two ends, both sides wallboard symmetric arrangement, and wallboard is provided with the bearing pin installing hole that skewed slot, locking trepanning and secure shroud that fast assembling-disassembling support roller parts use are used, and prevents the arc notch that rapping shaft is close to and establishes; Bottom and the rectangular opening that has confession drainage dust to use.Support roller is installed in the middle of the supporting-roller shaft, two ends buckle in the bearing skewed slot after being inserted in resistant to elevated temperatures sealed nylon cover and back-up ring, to lock condom to installing hole again locks, supporting-roller shaft can't be skidded off from skewed slot, axially move with split pin restriction locking cover the outer end of supporting-roller shaft, and support roller can rotate freely on supporting-roller shaft.Guard shield is a font, and the below is provided with the collar that usefulness is installed, the collar both sides that is placed in, and enough saturating skies are left in the centre, in order to avoid the bearing pin and the collar are killed by dust because of cooperation position is long; The bearing pin and the collar adopt big matched in clearance, by bearing pin, pad and split pin guard shield are fixed on the bearing.
Owing to set up the dust seal cover between support roller and the supporting-roller shaft, the stall phenomenon will be significantly improved, but still do not get rid of the possibility that stall can take place in long-time use, in case generation stall, the utility model needn't integral replacing dirt middle (center) bearing, as long as just replaceable impaired parts are withdrawed from split pin and locking cover, even when needing integral replacing dirt middle (center) bearing, also as long as guard shield is removed.But can relaxedly and rapidly install and remove all parts the service life of the version proper extension dirt middle (center) bearing that the utility model adopts, and improved installation, maintenance, the condition of work when changing, and reached its intended purposes.
