Abstract
The utility model belongs to the class of the transportation machinery, which is one of the components of a belt conveyor and is composed of three sets of rollers which are arranged at a turning rack. The middle part is a set of column rollers, and both sides are two sets of combined wimble rollers; the combined wimble rollers are composed of column tubes and conical tubes which are connected via flexible-elastic rings, and the frictional force generated by the speed difference of the combined wimble rollers pushes the roller support frame to rotate at a certain angle, which performs a centre-regulating action towards the rubber belt.
Description
The utility model belongs to the Transport Machinery class, is one of parts on the belt conveyer.
The utility model plays the aligning effect to the rubber belt from deviating of belt conveyer.Belt conveyer TD-75 standard has only unidirectional aligning carrier roller at present.In order to satisfy the actual needs of reversible belt conveyer, Haerbin Heavy-duty Machine Factory once made imitative day reversible aligning carrier roller, this carrying roller is made up of two awl rollers and a common post roller, links to each other with two universal couplings between three rollers, and roller rack can center on center steering.When belt conveyer moves, the garden circular velocity of common post roller is identical with tape speed, the garden speed governing degree of awl roller then reduces with diameter, thereby having produced friction force between adhesive tape and the awl roller, this friction force is zero to the algebraic sum of the moment that center of gyration formed when normal operation, so support is kept the home position, when rubber belt from deviating, above-mentioned resultant moment makes support revolution certain angle, to reach the aligning effect.But because of universal coupling diaxon angle of displacement has reached 30 °, exceeding range of use, so the life-span is extremely short, is unsurmountable shortcoming.
The purpose of this utility model is to solve existing short problem of life-span of imitating day reversible aligning carrier roller mechanism, in order to further specify, to press accompanying drawing below and introduces in detail; Fig. 1 is that the utility model " the reversible aligning carrier roller of differential flexible axle type " mechanism always schemes.Fig. 2 is combination carrying roller detail drawing.The utility model is made up of the garden cylindrical roller (1) and the combination tapered roller (2) that are loaded on the rotary support (3) as shown in Figure 1.Figure 2 shows that the detailed construction of combination tapered roller (2), the garden post roller (7) of surperficial line with rubber is connected with steel awl roller (5) through flexible resilient ring (6) (available rubber or other elastomeric material are made).(2) , And make that tan α=(D-d)/(2L), α is generally less than 5 ° to the bending mandrel (9) that has knuckle 2 degree of one's own through the combination tapered roller of being made up of cone roller (5) resilient ring (6) garden post roller (7) and bearing (8).Make like this after the α value, then outline line (10) must become a flat line on this combination tapered roller (2).Combination tapered roller (2) is loaded on support (3), and as shown in Figure 1, last outline line (10) is 30 ° of groove angle lines.When belt conveyer moves, identical with imitative day carrying roller, the garden circular velocity of unit's post roller (7) equals adhesive tape (seeing Fig. 1 imaginary line) speed, the garden circular velocity of awl roller (5) then reduces with diameter, thereby the friction force between the surface of adhesive tape and two combination tapered rollers (2) (see figure 1), the algebraic sum of the moment that center of gyration (4) is formed makes support (3) motionless, or positive and negative revolution certain angle, to reach the aligning purpose.
The utility model is compared with an existing imitative day aligning carrier roller, because of no longer needing star coupling between three rollers, and with the combination tapered roller of angle of displacement α<5 ° for it, so the life-span is long, cost is low, performance is good, long-term use does not need repairing.
Claims (3)
1, a kind of " the reversible aligning carrier roller of differential flexible axle type " mechanism includes garden post roller (1), combination tapered roller (2), and support parts such as (3).It is characterized in that combination tapered roller system is made up of garden post roller (7) flexible resilient ring (6) awl roller (5) bearing (8) and bending mandrel (9).Promptly garden post roller (7) and awl roller (5) are equipped with in the two ends of axle (9), and with flexible resilient ring (6) post roller (7) and awl roller (5) are linked.
2, " differential is scratched the reversible aligning carrier roller of the axle " mechanism described in claim 1 is characterized in that the line of centers bending angle α of bending mandrel (9) in the combination tapered roller (2) is generally less than 5 °.
3, " differential scratch axle a reversible aligning carrier roller " mechanism described in claim 1 is characterized in that making cone angle that the bending angle α of above-mentioned bending axis (9) equals to bore roller (5) half, i.e. tan α=(D-d)/(2L).
