Compared with a limit device of large rotating equipment in the prior art, the center longitudinal limit device provided by the utility model has the advantages that the friction resistance torque is reduced, the power is reduced, the energy is saved, and the rotating equipment can be safely and reliably limited to displace in multiple directions; and the center longitudinal limit device can be applicable to multiple kinds of large rotating equipment.
Description
Technical field
The utility model belongs to mechanical equipment technical field, and the central longitudinal that especially is specifically related to a kind of rotating equipment is to limit stoper.
Background technique
Left or right vertically moving inevitably takes place in known rotating equipment when load running, cause unnecessary damage to manufacturing mechanism, increases maintenance and cost of production.The large-scale rotating equipment that particularly runs up is particularly outstanding.For preventing the longitudinal leap of equipment, from the needs of control and protection equipment, when manufacturing and designing, consider the longitudinal spacing problem, to guarantee the stability of rotating equipment.Existing technology spacing mostly is to adopt spacing and the friction moment=frictional resistance * arm of force that circumference is spacing of circumference.So rotating equipment is big more, friction moment suffered on its edge is just big more, and the power (power=friction moment * angular velocity) that then consumes is also just big more, and power consumption is also just big more.Moreover the rotating speed of circumference limit stoper will make its easy abrasion life-span not long much larger than the rotating speed of rotating equipment like this.
Summary of the invention
The purpose of the utility model provides a kind of central longitudinal that is used for rotating equipment to limit stoper, can effectively prevent vertical left or right displacement of rotating equipment, and can prolong the working life of limit stoper.
The technological scheme of the utility model is that a kind of central longitudinal of rotating equipment comprises by hollow shaft, bearing sleeve back-up ring, bearing sleeve, bearing, bearing cap, spherical hinge device and spacing support device to limit stoper and forming; Described hollow shaft is the externally threaded hollow cylindrical metalwork of an end band.With one group of plane bearing place of externally threaded hollow shaft end to the hollow shaft end; Have one have an excessive degree of depth step; One group of plane bearing place, inboard on hollow shaft; Transition groove with the step deep equality of hollow shaft end is arranged, the outside thread with inner bearing sleeve back-up ring equal length is arranged on the right side of transition groove.
Described bearing sleeve back-up ring has two, and it is shaped as hollow round platform, is divided into outer bearing sleeve back-up ring and inner bearing sleeve back-up ring; Outer bearing sleeve back-up ring one end has the internal thread that matches with the hollow shaft outside thread; The other end has two kinds of patterns, is flange-type and sealed type, and the endoporus of flange-type bearing sleeve back-up ring is a through hole; Be used to have the cylinder rotating equipment of fixed charging Hatch Opening; The interior bore ends of sealed type bearing sleeve back-up ring is sealed, and is used to not have the cylinder rotating equipment of fixed charging Hatch Opening, and outer bearing sleeve back-up ring and hollow shaft are linked together by screw threads for fastening; Inner bearing sleeve back-up ring internal thread and hollow shaft drive fit.
Described bearing is stamped two; Periphery at bearing cap has the bolt hole that distributes equably; The center of bearing cap has and the close circular hole of bearing sleeve back-up ring external diameter, and bearing cap and bearing sleeve back-up ring external diameter are Spielpassung, and there is a seal groove circular hole center; Dynamic seal ring is housed in the groove, a diameter and the corresponding to round platform of bearing sleeve internal diameter are arranged in the inboard of bearing cap.During final assembly, bearing cap is to be fixedly connected with bolt, nut with the end closure plate of rotating equipment.
Described bearing sleeve is the hollow cylinder that two ends have flange, and its internal diameter is consistent with the inboard round platform diameter of bearing cap, and the screw of flange is consistent with the screw of bearing cap, and a seal groove is arranged on the exterior edge face of flange, and the static seal circle is arranged in the groove.Have oil inlet hole on the bearing sleeve, can be oily to bearing.
Described bearing is divided into plane bearing and radial bearing, and two of plane bearings are one group, has two groups; Be contained in two hollow shaft groove transition positions between the hollow shaft sleeve; Between two groups of plane bearings, two radial bearings are housed, adorn a cylindric back-up ring between two radial bearings; Between plane bearing and radial bearing, round platform formula back-up ring is housed.Two radial bearings mainly play a supportive role to bearing sleeve, and the back-up ring between its radial bearing mainly is that two radial bearings are played the role of positioning.Two groups of plane bearings of the right and left are main work bearings; When left and right sides radial displacement appearred in the cylinder rotating equipment, rotating speed was complementary between bearing on the same group, when a bearing goes wrong; Can not influence its proper functioning yet, thereby prolong the working life of longitudinal spacing device.
Described spherical hinge device is formed by not passing hollow billiard table and overhead gage, lower pedal with two parallel cuts with externally threaded hollow axle end; Last lower pedal has two pairs; Lower pedal is welded on upper plate, and hollow billiard table is packed in two lower pedals, and last lower pedal connects with bolt.
Described spacing support device is that a spacing cushion block is arranged on spacing base; On the spacing cushion block direction vertical with hollow shaft, two parallel T type grooves are arranged, it is fastening with nut that T type bolt passes lower shoe; With bolt and nut lower shoe and upper plate are housed fixedly in the above; On corresponding two sides of upper and lower bottom plate, the left end of upper plate and the right-hand member of lower shoe are equipped with otic placode respectively, and the otic placode of upper and lower bottom plate links to each other with leading screw.The longitudinal spacing device can also can be adjusted the height up and down of longitudinal spacing device through the adjustment leading screw through sliding before and after the T type groove.
Hollow shaft in the longitudinal spacing device of the utility model does not rotate; Have only the bearing cap and the bearing sleeve that are connected with the rotating equipment closure plate to rotate; Adopt little Spielpassung between the bearing cap of non-rotary hollow shaft and rotation and the bearing sleeve; Can the fine power of reducing friction, thus working life of longitudinal spacing device prolonged.When rotating equipment will vertically move, the longitudinal spacing device can finely limit it and vertically move, thereby played good position-limiting action.In the time of rotating equipment and longitudinal spacing device decentraction, the spherical hinge containment in the longitudinal spacing device is fine, can effectively prevent off(-)center.Between bearing cap and the outer bearing sleeve back-up ring, all adopt seal ring sealing, good sealing effect between bearing cap and the bearing sleeve.
The beneficial effect of the utility model is: compare with the limit stoper of the large-scale rotating equipment of existing technology, this limit stoper structure is at the center of rotating equipment the longitudinal spacing device to be set, and the arm of force reduces, and then friction moment reduces, power reduction thus, conserve energy; Simple in structure, easy for installation, the length travel and the circular runout of restriction rotating equipment that can be safe and reliable, applicability is wide.Can be widely used in the center longitudinal spacing of rotating equipments such as high speed centrifugation injection machine, cylinder type cold slag machine, roller dryer, roller milling machine.
