Abstract
The utility model provides a spiral body supporting device and belongs to the field of conveying machinery accessories, which comprises a spiral body composed of a plurality of spiral blades and a spiral shaft. A casing is arranged outside the spiral body, a plurality of supporting shafts are arranged on the arc face on the inner side of the casing along the longitudinal direction, the supporting shafts are inserted into circular rings which are fixed at two ends of the casing and are in clearance fit with round through holes of the circular rings, and the outer edges of the spiral blades are in rolling contact with the supporting shafts. The spiral body supporting device has the advantages that the outer edges of the spiral blades are in rolling contact with the supporting shafts, thereby being small in frictional resistance and long in service life; and the supporting structure does not need to be lubricated, and the supporting shafts are convenient to change after being abraded, thereby being low in maintenance cost, simple in structure and suitable for various spiral conveyers.
Description
Technical field
The utility model relates to a kind of conveyor screw bracing or strutting arrangement, belongs to conveying machinery accessory field.
Background technology
When the conveyor screw delivered length surpasses 3 meters, will combine by several conveyor screws, connect by adapter shaft between two conveyor screws, adapter shaft is provided with suspension bearing, plays the effect of support helix body.The bearing that suspension bearing adopts has two kinds on antifriction-bearing box and bearing shell, because suspension bearing is operated in the dust, is difficult to guarantee that dust does not enter in the bearing, in case dust enters in the bearing, suspension bearing very quick-wearing lost efficacy, and the maintenance cost height is changed very inconvenient.Because suspension bearing is short service life, often maintenance has also influenced carrying out continuously of producing.Though existing patent proposes some technical schemes around the improvement of suspension bearing, does not all tackle the problem at its root.Particularly,, also there is not good solution because suspension bearing is installed difficulty at vertical screw type conveyer.
The utility model content
The purpose of this utility model is the technological deficiency that overcomes suspension bearing, and a kind of replaceable suspension bearing is provided, and can be applicable to the conveyor screw bracing or strutting arrangement of various conveyor screws.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of conveyor screw bracing or strutting arrangement, comprise the conveyor screw of forming by some helicallobes and screw shaft, described conveyor screw outside is provided with housing, the arc surface of described housing inboard longitudinally is placed with some pivot shafts, described pivot shaft inserts and is fixed in the annulus at housing two ends, the round open-work of described pivot shaft and annulus forms free-running fit, forms rolling touch between described helicallobe outer rim and the pivot shaft.
As preferably, described housing is " U " shape slot shell or tubular shell.
As further preferred, described pivot shaft is three, and one is positioned at " U " shape slot shell bottom, and two symmetries are placed on both sides in addition; The formed angle β of the axle center of supported on both sides axle and screw shaft axial connecting line changes between 90 °～120 °.
As further preferred, described pivot shaft is three, is uniformly distributed in the inboard of tubular shell.
As preferably, be fixed with some parallel lead-ins between inboard three pivot shafts of described housing.
As further preferred, described lead-in and housing are isometric.
As further preferred, form the gap of 8mm～12mm between the outer rim of described helicallobe and the lead-in.
The beneficial effects of the utility model are that owing to form rolling touch between helicallobe outer rim and the pivot shaft, friction drag is little, long service life; This supporting construction does not need to lubricate, and is convenient to change after the pivot shaft wearing and tearing, and maintenance cost is low, and is simple in structure, applicable to various types of conveyor screws.
Description of drawings
Fig. 1 is the front view that the utility model is used for horizontal screw conveyer;
Fig. 2 is the left view that the utility model is used for horizontal screw conveyer;
Fig. 3 is the scheme drawing that the utility model is used for vertical screw type conveyer.
Institute's label declaration is as follows among the figure:
1-" U " shape slot shell, 2-helicallobe, 3-screw shaft, 4-annulus, 5-pivot shaft, 6-lead-in, β-supported on both sides axle axle center and the formed angle of screw shaft axial connecting line, 7-tubular shell.
The specific embodiment
Conveyor screw has three types, i.e. horizontal screw conveyer, vertical screw type conveyer and tilting screw conveyer.
Embodiment 1
As depicted in figs. 1 and 2, present embodiment is the utilization of bracing or strutting arrangement at horizontal screw conveyer, tilting screw conveyer, and the housing of these two kinds of conveyor screws all is " U " shape groove.The technical scheme that provides is: a kind of conveyor screw bracing or strutting arrangement, comprise conveyor screw, " U " shape slot shell 1, described conveyor screw is to be welded by some helicallobes 2 and screw shaft 3, described " U " shape slot shell 1 inside is " U " type groove, described conveyor screw longitudinally is installed on " U " in " U " shape groove of shape slot shell 1, the arc surface of described " U " shape groove inboard is longitudinally placed some pivot shafts 5, and pivot shaft 5 can be solid circular shaft, also can be steel pipe.For stress equalization, 5, one of three pivot shafts of parallel placement are positioned at the bottom, and two symmetries are placed on both sides in addition, and the formed angle β of the axle center of supported on both sides axle and screw shaft axial connecting line changes between 90 °～120 °.Pivot shaft 5 inserted is fixed in " U " in the annulus 4 at shape slot shell 1 two ends.Specifically, annulus 4 is welded in " U " shape slot shell 1 inboard, " U " shape slot shell 1 longitudinal length changes between 1.5m to 3m.Pivot shaft 5 forms free-running fit with annulus 4 circle open-works, can rotate therein.Specifically, change between 1mm to 3mm in its gap.Helicallobe 2 outer rims contact with pivot shaft 5, when conveyor screw rotates, form friction of rolling between them.This supporting construction does not need to lubricate, and is convenient to change after pivot shaft 5 wearing and tearing, and maintenance cost is low, and is simple in structure.
Adopt pivot shaft 5 support helix blades 2 outer rims, make the inboard gap greatly that forms of helicallobe 2 outer rims and " U " shape groove, general gap is between 30mm to 50mm, and big like this gap can reduce the traffic capacity of conveyor screw, in order to address this problem, also secured in parallel has and the isometric lead-in 6 of " U " shape groove between inboard three pivot shafts of U-lag.By adjusting the thickness of lead-in 6, be advisable in the gap that forms 8mm～12mm between helicallobe 2 outer rims and the lead-in 6.Lead-in 6 available metal materials, also available abrasion resistant non-metallic material.Lead-in 6 can be welded on the U-lag inboard, also can adopt screw to connect.
Embodiment 2
As shown in Figure 3, be the scheme drawing that the utility model is used for vertical screw type conveyer, difference from Example 1 is, comprises that 7, three pivot shafts 5 of tubular shell are uniformly distributed in the inboard of tubular shell 7.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
