Abstract
The utility model relates to a hanging bearing of a spiral conveying machine, which has the advantages of convenient and rapid replacement, reliable bearing sealing and good aligning performance. A double-face sealing ball bearing or a sliding bearing is sheathed on a middle mandrel, and semi cylinders are arranged at both ends of the middle mandrel. Semicylinders with the same length are also arranged at one end of a left coupling shaft and a right coupling shaft. The semi cylinders at both ends of the middle mandrel are respectively and mutually buckled with the semi cylinders at one end of the left coupling shaft and the right coupling shaft. The coupling shafts and the middle mandrel are connected by a bolt and a baffle ring. The utility model adopts the double-face sealing ball bearing to replace the aligning ball bearing in the prior art, and a spherical washer which is arranged at the connecting part of a hanging rod and a supporting plate is used for aligning. The utility model overcomes the defect of inconvenient disassembly of a 'plug shaft type' connecting hanging bearing in the prior art, and simultaneously, the utility model has the advantages of small resistance material area, low manufacturing cost, no pollution for materials, good dust-proofing effect, etc.
Description
Technical field
The utility model relates to a kind of conveyor screw suspension bearing.
Background technology
When helical feed material distance surpasses 3 meters, produce bending phenomenon in order to prevent screw shaft, every a segment distance suspension bearing will be set, so the suspension bearing requisite critical component that is conveyor screw.General suspension bearing is arranged on and is used to connect two sections spirochetal tween drive shafts.Conveyor screw and connecting mode between the conveyor screw have and a kind ofly connect for " insert shaft type " in the prior art." insert shaft type " connection is about to a smooth tween drive shaft and inserts in the spiral tube, and is fastening fixing to wearing tween drive shaft and spiral tube along mutually perpendicular direction with two attachment bolts again.The major advantage of this connection is: simple in structure, connect reliably, and centering property is good, and running is steadily; Contour dimension is less, can reduce the resistance to material.Subject matter is: the installation and maintenance difficulty, because tween drive shaft will insert in the spiral tube, when changing consumable accessory bearing or tween drive shaft, must move heavy conveyor screw, and strengthened workman's maintenance load.
The bearing that conveyor screw suspension bearing of the prior art adopts has two kinds on antifriction-bearing box and plain bearing, and in order to reach the purpose of aligning, antifriction-bearing box is generally used self-aligning ball bearing, and this bearing is very tight to seal request, and wants frequent oil injecting lubricating.Because suspension bearing is operated in the dust, be difficult to guarantee that dust does not enter in the bearing, in case dust enters in the bearing, bearing very quick-wearing lost efficacy.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned conveyor screw suspension bearing use, provides a kind of replacing convenient and swift, and bearing felt is reliable, and has the conveyor screw suspension bearing of good aligning performance.
The technical scheme that its technical matters that solves the utility model adopts is: the conveyor screw suspension bearing comprise be arranged in the middle of bi-face sealed ball bearing or plain bearing on the mandrel, in the bearing seat, bearing seat is provided with pull bar, pull bar and back plate link, the mandrel two ends are provided with one section semicylinder in the middle of it is characterized in that, one end of left and right sides coupling spindle also is provided with the semicylinder of equal length, and the semicylinder at middle mandrel two ends is the state that is fastened mutually with the semicylinder of left and right sides coupling spindle one end respectively.
Opposite position at left and right sides coupling spindle and middle mandrel is provided with through hole, and bolt passes two corresponding through holes captives joint coupling spindle with middle mandrel.Be provided with a pair of spherical washer that is the sphere contact condition above back plate, after pull bar passes spherical washer and back plate in proper order, captive joint with bearing seat in the lower end.The both ends of the surface of bearing seat are arranged with lid, cover the arrangement of bores leakproofing material thoroughly.
The beneficial effects of the utility model are to have overcome prior art " insert shaft type " to connect the dismounting inconvenience shortcoming that suspension bearing exists, and during maintenance, as long as extract two bolts out, suspension bearing integral body can be pulled down.Have again simultaneously that the resistance material area is little, aligning performance good, the advantage such as pollution-free and good dustproof effect to material.

The specific embodiment
As shown in Figure 1, with the both sides of back plate 5 crosswise fixed at the conveyor screw hopper.On back plate 5 centre holes, be provided with spherical washer 4.Pull bar is provided with outside thread in two ends about in the of 1, and the lower end is threaded with bearing seat 7, uses nut 6 fastening again.The upper end screw thread is connected with double nuts 2, and spherical washer 3 and the spherical washer 4 that are enclosed within on the pull bar 1 contact by sphere.Bi-face sealed ball bearing 9 inner rings cooperate with middle mandrel 18, and the outer ring cooperates with bearing seat 7 housing bores.As adopt plain bearing, then plain bearing and middle mandrel 18 free-running fits.For strengthening dustproof effect, be arranged with at bearing seat 7 two ends and cover 8, fixing with 4 to 6 flathead screws 19, at the arrangement of bores leakproofing material 10 of saturating lid 8.Left and right sides coupling spindle 17 inserts respectively in conveyor screw 14 pipes, again with attachment bolt 15 along mutually perpendicular direction to wearing coupling spindle 17 and conveyor screw 14 pipes, fixing with double nuts 16.The semicylinder of left and right sides coupling spindle 17 1 ends snaps together mutually with the semicylinder at middle mandrel 18 two ends respectively, overlaps upper baffle ring 13 respectively, is connected with double nuts 12 with bolt 11 again.
During maintenance, only need turn on double nuts 12, extract bolt 11 out, baffle ring 13 is shifted to both sides, suspension bearing integral body can be pulled down.The left and right sides coupling spindle 17 that links to each other with conveyor screw 14 by attachment bolt 15 needn't unload, and conveyor screw 14 also needn't move.Can alleviate working strength of workers thus and shorten maintenance time.
As shown in Figure 2, the end at coupling spindle 17 is provided with one section semicylinder.
As shown in Figures 2 and 3, on the semicylinder plane, be provided with through hole.
As shown in Figure 4, be provided with the semicylinder of equal length at the two ends of middle mandrel 18.
As shown in Figure 4 and Figure 5, at both ends semicylinder plane is provided with through hole.
