Description
Technical field
The present invention relates to a kind of bearing set, the device that particularly a kind of helicallobe that is used for conveyor screw supports, this device does not take effective conveying basal area of conveyor screw.
Background technology
At present, in the conveyor screw that generally uses, one or more drop-hanger bearing devices are installed all on its screw shaft,, make machine normally not move to prevent not only thin but also long screw shaft flexural downwarping.Yet, when increasing the drop-hanger bearing device, also be accompanied by the appearance of many new problems: the first makes the helicallobe can not be continuous, position at each drop-hanger bearing device must disconnect, make the payload space of helicallobe participation work correspondingly reduce, caused material to be obstructed, operational throughput reduces; It two is that screw shaft be difficult to guarantee to make in the machine run easily and break down with one heart under the situation of multi-point support; It three is that the drop-hanger bearing device is subjected to the influence of material on every side, and its lubricity is destroyed, and greatly reduces its service life, has brought difficulty for the maintenance of equipment; It four is the shells that need open conveyor screw when safeguarding the drop-hanger bearing device, and As time goes on the increasing of maintenance times, its airtight performance causes more serious pollution also along with reduction to surrounding environment.
Summary of the invention
The invention provides a kind of helical blade supporting arrangement that does not have the conveyor screw of drop-hanger bearing bearing set, thoroughly having solved existing conveyor screw reduces because of the operational throughput that the existence of drop-hanger bearing device brings, in servicely break down easily, the lubricity of drop-hanger bearing device is destroyed the problem that reduces with airtight performance.
The technical solution adopted for the present invention to solve the technical problems is:
Helical blade supporting arrangement, the delivery pipe 1 that comprises conveyor screw, helicallobe 4, this bearing set 3 is arranged between the shell of delivery pipe 1 of one section intercepted conveyor screw, the two ends by the truncated position of delivery pipe 1 are respectively arranged with flange 2, described bearing set 3 is two semi-round bodys, a pipeline with delivery pipe 1 uniform internal diameter of conveyor screw is formed in butt joint back, middle part on this semi-round body 10 is provided with several slots 13, the two ends in the outside of this semi-round body 10 are respectively arranged with flange 7 and anvil roll mount pad 8, semi-round anvil roll mount pad 8 is provided with the mounting groove 9 of anvil roll 11, anvil roll 11 is installed in the mounting groove 9, and the part of the roll body of anvil roll 11 embeds in the slot 13.
The two ends of the axle 18 of described anvil roll 11 can have positioning groove, and the anvil roll pressing plate 12 by fixing with bolted connection 15 and anvil roll mount pad 8 is fixed on 9 li of anvil roll mounting grooves with axle 18.
The bottom surface is provided with blind hole in the middle of the positioning groove at described axle 18 two ends, wherein is provided with brute spring, guarantees helicallobe 4 and anvil roll 11 closed contacts.
Simultaneously, because anvil roll 11 is that rigidity contacts with helicallobe 4, the edge that contacts with anvil roll 11 at helicallobe 4 studs with fringing 5, this fringing is made by elastomeric material wear-resisting and that lubricity is good, to increase the area of contact of helicallobe 4 and anvil roll 11, improving helicallobe and roller stability in contact, and can prevent the stressed excessive and flexural deformation of blade edge.For preventing material from leakage, stud with packing seal at the periphery of mounting groove 9, to guarantee the sealing between anvil roll 11 and the mounting groove 9.
The present invention has solved the screw shaft support problem in the conveyor screw well, prevented the flexural downwarping of screw shaft effectively, realized the unimpeded of mass transport and improved traffic capacity greatly, overcome existing conveyor screw need frequent maintenance and service life low shortcoming.

The specific embodiment
The present invention will be described below in conjunction with accompanying drawing:
The present invention is made up of two semi-round tubular support devices 3 of symmetry, butt flange 2 on the bolt together spiral tube 1 and the butt flange 7 on the midship mounting device, two and half bearing sets 3 of symmetry are coupled together at vertical butt flange 12 places with bolt, insert in the open circuited spiral tube 1.Uniform a plurality of bolts hole are arranged on the flange 2 of spiral tube 1, and the bolt hole on the butt flange 7 on bolt hole and the intermediate supporting device is corresponding.Packing seal all is housed between each butt flange.At last, outer cover 6 is installed on the intermediate supporting device 3, can connect with bolt or other dismantled and assembled modes, edge at the helicallobe 4 that contacts with anvil roll 11 is added with cushion ledge 5, to increase the area of contact of helicallobe 4 and anvil roll 11, improve helicallobe 4 and anvil roll 11 stability in contact, reduce the application force between them, reduce wearing and tearing, increase the service life.
The semi-round mount pad of two semi-round butt flanges 7, two 8, two vertical butt flanges 14 are arranged on the semicircle bearing set 3.On two butt flanges 7 of symmetry uniform a plurality of bolts hole are arranged respectively.When the utility model uses in conveyer, the flange 2 on flange on the intermediate supporting device 37 and the spiral tube 1 is coupled together with bolt.Have a plurality of anvil roll mounting grooves 9 on two symmetrical semi-round mount pads 8, a plurality of anvil rolls 11 are installed in the anvil roll mounting groove 9.The two ends of the axle 18 of anvil roll 11 have positioning groove, and the anvil roll pressing plate 12 by fixing with bolt 15 and anvil roll mount pad 8 is fixed on axle 18 in the anvil roll mounting groove.The bottom surface is drilled with blind hole in the middle of positioning groove, wherein places brute spring to guarantee helicallobe 4 and anvil roll 11 closed contacts.
