Description
Technical field
The invention belongs to cement industry clinker burning field, particularly relate to a kind of self-potential riding wheel supporting device of rotary cement kiln.
Background technology
The riding wheel supporting device that is applied to rotary cement kiln exists because the immerge of many fulcrums rotary kiln, the stressed extremely uneven situation that kiln cylinder body alignment error and support roller adjustment error etc. cause, EDGE CONTACT appears between wheel band and support roller, even bearing reaction changes two grades of little supporting kilns, because the flexural deformation of kiln cylinder body, also can produce EDGE CONTACT between wheel band and support roller, make the wheel band contact inhomogeneous with support roller, the wheel band is excessive with the local contact stress of support roller, influence the service life of wheel band and support roller greatly, therefore be necessary to adopt self-potential riding wheel supporting device.Present each famous cement machinery Chevron Research Company (CRC) of world strength that releases one after another, hydraulic pressure and block rubber self-potential riding wheel supporting device, strength and hydraulic pressure self-potential riding wheel supporting device complex structure, maintenance load is big, cylinder and hydraulic jack be its effect and unsatisfactory under many dirt and hyperthermia radiation condition, and replace cylinder and hydraulic jack with the elastic block rubber of bridge pad, then can simplify the structure of supporting arrangement greatly, improve the reliability of its use, but present some block rubber self-potential riding wheel supporting devices of using, the middle part bearing pin adopts rigidity to connect on its structure, the self-alignment of limit structural to a certain extent promptly takes place to be difficult to guarantee that support roller contacts with wheel band linearity when crooked when the wheel band.
Summary of the invention
The present invention can improve cement rotary kiln real-world operation situation for the technical problem that exists in the solution known technology provides a kind of, improve the service life of critical component wheel band and support roller, alleviate rotary kiln heavy casting and forging weight, reduce equipment manufacturing cost, simple in structure, use reliably self-potential riding wheel supporting device of rotary cement kiln easy to maintenance.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of self-potential riding wheel supporting device of rotary cement kiln, connect to form by movable bearing support, base, rubber base, radial elastic piece and lateral elasticity piece, be characterized in that described movable bearing support forms by the axle that two thrust articulated bearings and plain radial bearing structure are connected by travel(l)ing rest and at the travel(l)ing rest head.
The present invention can also adopt following technical measures to realize:
Above-mentioned a kind of self-potential riding wheel supporting device of rotary cement kiln, the centre of sphere that is characterized in described two thrust articulated bearings and a plain radial bearing intersects on the intersection point of horizontal and vertical center line of institute's connecting axle, and the inner cylinder face of three oscillating bearings forms an articulated structure with axle.
Above-mentioned a kind of self-potential riding wheel supporting device of rotary cement kiln is characterized in that the two ends of described axle are the square body structure, and movable bearing support one end is connected on the base by the square body at axle two ends, and the other end is supported on the radial elastic piece that is positioned on the rubber base.
Above-mentioned a kind of self-potential riding wheel supporting device of rotary cement kiln is characterized on the rubber base of described movable bearing support side side connecting plate being installed, and the lateral elasticity piece is housed on the side connecting plate, and certain clearance is left in lateral elasticity piece and movable bearing support side.
The advantage that the present invention has with good effect is: 1, because the travel(l)ing rest head on the movable bearing support adopts the centre of sphere of two thrust articulated bearings and a plain radial bearing structure and three oscillating bearings to intersect on the same point with being connected of axle, guaranteed that movable bearing support can do oscillating motion around centre of sphere point, the end that movable bearing support is connected with the radial elastic piece is done synchronous oscillating motion, thereby reach the purpose of eliminating wheel band and support roller generation skewness, make support roller and wheel band even contact.2, because the square body of movable bearing support one end by the axle two ends is bound up on the base, axle does not rotatablely move with regard to not producing that to become fixed axis be so-called axle like this.The other end is bearing on the radial elastic piece that is positioned on the rubber base, inner cylinder face by three oscillating bearings between travel(l)ing rest head on the movable bearing support and the axle forms articulated structure with axle, guaranteed that movable bearing support can rotate around axle, the end that movable bearing support is connected with the radial elastic piece can be done down shifting movement, thereby reach the purpose of eliminating wheel band and the empty phenomenon of support roller holder, make support roller both sides stress equalization.3, the travel(l)ing rest head on the movable bearing support not only is provided with plain radial bearing but also be provided with two thrust articulated bearings; therefore this structure not only can bearing radial force but also can have been born axial force; and the lateral elasticity piece that is equipped with on the side connecting plate of installing on the rubber base of movable bearing support side; can more effectively bear the axial force of support roller, leave simultaneously the gap between movable bearing support side and the lateral elasticity piece and can guarantee that movable bearing support does oscillating motion around centre of sphere point and can not be subjected to the side connecting plate interference.It is to regulate the support roller position automatically that the present invention has advantage, make support roller follow the wheel band constantly beat takes place, all the time keep the wheel band and contact to reach desirable operating mode along overall with, improve support roller and the working life of taking turns band, can guarantee that also multi-point support is all stressed simultaneously with support roller.
