Description
Technical field
The utility model relates to the broken arch feeding bin equipment in feed or the food-processing industry, particularly a kind of broken arch feeding bin mixer sealing and supporting construction.
Background technology
In feed or food-processing industry, the less material fluidity of the material in the feed bin, particularly grinding particle size is bad, is easy to knot arch in feed bin, causes the situation of the unstable or fracture of feeding, influences the normal operation of next procedure.For guarantee material in the feed bin can the feeding of continous-stable under in the road, all must install mixer additional in the feed bin bottom.Existing mixer mounting means is: the mixer main shaft directly inserts in the reductor hollow shaft that links to each other with the feed bin bottom and is connected through key, and what adopted in mixer main shaft and lower shaft hole, storehouse is the polytetrafluoroethylene packing seal form.This simple in structure, easy for installation, but mixer main shaft and the employing of reductor axis hole is free-running fit; Supporting form is equivalent to a kind of cantilever support, owing to unbalance stress around mixer is when stirring material, will inevitably produce and rock; This rocking is reflected at packing seal place and will produces very big radial run-out; Dust is got in the slit of filler and axle, cause the filler self-lubricating to lose efficacy, quicken the wearing and tearing of axle; Mixer itself bears very big axial force in addition; This axial force all acts on the reductor through the mixer main shaft; The parallel shafts helical speed reduction gear that adopts on the feeding bin can not bear axial force; Be easy to cause bearing in reduction gears to damage like this, thereby damage bearing seal, cause the reductor leakage of oil.
The utility model content
The utility model provides a kind of sealing and supporting construction of broken arch feeding bin mixer to the problem that prior art exists, and is intended to protect the reductor of feeding bin bottom and prevents the material leakage.
The purpose of the utility model is to realize like this; A kind of sealing and supporting construction of broken arch feeding bin mixer comprise the mixer main shaft, and said main shaft stretches out mixer outside from mixer bottom and is sleeved in the hollow axis hole of reductor through key connection carry-over moment; Said main shaft is rotationally connected through bearing and bearing seat and feeding bin base plate; Said bearing seat is captiveed joint with the feeding bin base plate, is provided with direction two opposite groups bearing between bearing seat and main shaft in opposite directions, and the two bearings outer end is provided with bearing cap shim.
Adopt the structure of the utility model; The axial force that mixer itself bears; Can act on the base plate of feeding bin through mixer main shaft, bearing, roller bearing end cap, connecting panel; The reductor main shaft connects only transfer torque to the mixer main shaft through key, no longer bears axial force, and actv. has been protected reductor.
Main shaft produces and rocks when avoiding around the mixer unbalance stress, and said bearing is a tapered roller bearing, has avoided the stressed impact to reductor.
Further improvement as the utility model; Said feeding bin bottom is provided with the permanent seat that is used for reductor and bearing seat are fixed in the annular arrangement bottom the feeding bin; Said permanent seat one end margin is provided with first flange that extends radially inwardly; Permanent seat other end edge is provided with second flange that extends radially outwardly; Said fixed seating is loaded on outer also the welding through the first flange plane and feeding bin base plate of bearing seat and fixes, and said bearing seat is captiveed joint through connecting panel with first flange, and said second flange is captiveed joint with reductor.Like this, what the connecting panel and first flange adopted is the plane static connection, and material in the feeding warehouse has been played good sealing function.
For further guaranteeing first flange and connecting panel bonded assembly stationarity and leak tightness, be provided with the annular table terrace of mutual interlock between said first flange and connecting panel.
For making things convenient for the lubricated of bearing, be provided with between the bearing seat of said two groups of bearings the lubricating ester interpolation pipe that radially outward stretches out and pass permanent seat.
For guaranteeing reductor bonded assembly fastness, be welded with some reinforcement square tubes between the annular arrangement periphery of said permanent seat and feeding bin base plate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1 bearing cap shim; 2 bearings; 3 bearing seats; 4 feeding bin base plates; 5 strengthen square tube; 6 reductors; 61 reductor hollow shafts; 7 main shafts; 8 permanent seats; 81 first flanges; 82 second flanges; 9 connecting panels; 10 lubricating esters add pipe.
The specific embodiment
Be illustrated in figure 1 as the sealing and the supporting construction of the broken arch feeding bin mixer of the utility model; Comprise mixer main shaft 7; Main shaft 7 stretches out outside the mixer and is sleeved in reductor hollow shaft 61 holes from the mixer bottom and connects carry-over moment through key; Main shaft 7 is rotationally connected through bearing 2 and bearing seat 3 and feeding bin base plate 4, and bearing seat 3 is captiveed joint with feeding bin base plate 4, and 7 on bearing seat 3 and main shaft are provided with direction two opposite groups bearing 2 in opposite directions; Two bearings 2 outer ends are provided with bearing cap shim 1, and this bearing cap shim 1 is connected with the screw retention of bearing seat 3 through circumferential distribution; Bearing 2 is a tapered roller bearing; The feeding bin bottom is provided with the permanent seat 8 that is used for reductor 6 and bearing seat 3 are fixed in the annular arrangement of feeding bin bottom; Permanent seat 8 one end margins are provided with first flange 81 that extends radially inwardly; Permanent seat 8 other end edges are provided with second flange 82 that extends radially outwardly; It is outer and fixing through first flange, 81 planes and 4 welding of feeding bin base plate that permanent seat 8 is set in bearing seat 3; Bearing seat 3 is captiveed joint through connecting panel 9 with first flange 81, and connecting panel 9 adopts with bearing seat 3 and is welded to connect, and second flange 82 and reductor 6 are connected through bolt; 9 of first flange 81 and connecting panels are provided with the annular table terrace of mutual interlock; 3 of the bearing seats of two groups of bearings 2 are provided with the lubricating ester interpolation pipe 10 that radially outward stretches out and pass permanent seat 8; 4 of the annular arrangement periphery of permanent seat 8 and feeding bin base plates are welded with some reinforcement square tubes 5.
