Description

Belt conveyor's pulley

Technical field

The utility model is related to belt conveyor's pulley.

Background technology

Ribbon conveyer is the material transfer equipment of application field widely, and has realized the professional standard of design selection Change, roller is mostly made using following processing technology all the time as critical component therein：Q235 steel plate cuttings --- --- longitudinal measure connects disk with casting and docks circular seam welding rolled cones skin into cylinder type --- school circle annealing simultaneously processes end groove --- Connecing --- processing connects disk endoporus and is connected with axle with key or expansion set connection.The main feature of this roller is exactly a skin and connects disk pair Connect and be welded into one.It is mostly close and welding performance is preferable using chemical composition because considering cylinder skin and connecing the welding performance of disk Low carbon-structural steel, this material can not be by heat treatment reinforcement, and strength grade is relatively low, the composite factors such as alternate load effect Under, there is a skin CRACKING ACCIDENT during welding heat affected zone near circumferential weld, in turn result in the large area tear of transportation rubber belt, shadow Roller is rung using safety, and larger economic loss is brought to user.In addition drum skin welds together with connecing disk, structure bulky, Roller need to integrally be returned to repair in shop when assembled in situ and maintenance difficult, more creeling skin and clad to answer, waste of time, spare part expense compared with It is high.

Utility model content

The utility model aims to solve the problem that the above mentioned problem defect of roller, so as to provide a kind of rational in infrastructure, technique is simple, peace It is complete reliable, it is easy to live more creeling skin and clad, saves the belt conveyor's pulley of spare part expense.

The utility model solves described problem, and the technical scheme of use is：

A kind of belt conveyor's pulley, including cylinder skin and connect disk, cylinder skin and connects disk for detachable connection structure.Using upper The utility model of technical scheme is stated, compared with prior art, the characteristics of it is protruded is：

Cylinder skin is detachable connection structure with disk is connect, and cylinder skin is with connecing disk without girth welding, welding heat affected area, solderless Defect is connect, suitably cylinder skin is made with the poor high-strength material of solderability, bearing capacity is big, and technique is simple, and reliable in quality can be avoided Cylinder skin cracking and adhesive tape tear accident, are conveniently replaceable a skin and clad, save spare part expense.

Preferably, the utility model further technical scheme is：

Cylinder skin is arranged on by expansion set and connect on disk.

Expansion set includes bipyramid outer shroud and bipyramid inner ring, and bipyramid hold-down ring is provided between bipyramid outer shroud and bipyramid inner ring, double High-strength bolt is provided between cone hold-down ring, high-strength bolt is progressively fastened to required torque value, tightens high intensity During bolt, it can make to produce normal pressure between bipyramid hold-down ring, bipyramid outer shroud, the contact surface of bipyramid inner ring and female surface, the normal pressure It is ultimately applied to the intracutaneous wall of high intensity cylinder and connects disk outer round surface, make to produce frictional force together between contact surface, realizes that roller is overall Swelling connects and transmits certain moment of torsion, and structural stability is strong.

Brief description of the drawings

Fig. 1 is the utility model example structure schematic diagram, i.e., cylinder skin is arranged on by expansion set and connect on disk.

Fig. 2 is the partial enlarged drawing of A in Fig. 1.

In figure：First bearing seat 1, axle 2, inner expension cap 3 connects disk 4, expansion set 5, cylinder skin 6, second bearing seat 7, bipyramid hold-down ring 8, bipyramid outer shroud 9, high-strength bolt 10, bipyramid inner ring 11, clad 12.

Embodiment：

With reference to embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands the utility model Content, therefore, the cited case are not intended to limit protection domain of the present utility model.

Referring to Fig. 1, Fig. 2, cylinder skin 6 by expansion set 5 be arranged on connect on disk 4, during assembling, first by axle 2 by inner expension cap 3 with connecing It is overall that the fastening of disk 4 turns into a rigidity, then expansion set 5 and cylinder skin 6 are inserted in successively meet the cylindrical place of disk 4, and one layer is provided with outside cylinder skin 6 Clad 12, expansion set 5 includes bipyramid outer shroud 9 and bipyramid inner ring 11, and bipyramid pressure is provided between bipyramid outer shroud 9 and bipyramid inner ring 11 High-strength bolt 10 is provided between tight ring 8, bipyramid hold-down ring 8, each part relevant position is adjusted by location dimension, high-strength Degree bolt 10 is progressively fastened to required torque value, when tightening high-strength bolt 10, can make bipyramid hold-down ring 8, bipyramid outer shroud 9th, produce normal pressure between the contact surface and female surface of bipyramid inner ring 11, the normal pressure be ultimately applied to high intensity cylinder the inwall of skin 6 and The outer round surface of disk 4 is connect, makes to produce frictional force together between contact surface, the overall swelling connection of roller is realized and transmits certain moment of torsion, tie Structure stability is strong, and then first bearing seat 1 and second bearing seat 7 are assembled on axle 2 again.

During more creeling skin 6, high-strength bolt 10 is unclamped one by one, take appropriate lifting auxiliary can easily by cylinder skin 6 from Connect disk 4 and first bearing seat 1 or the side of second bearing seat 7 is taken out, if need to only change rapid wear clad 12, cylinder need not be dismantled Skin 6, because cylinder skin 6 is with connecing disk 4 without girth welding, welding heat affected area can be showed using the clad 12 of cold-adhered Field processing and reparation.

Cylinder skin 6 by expansion set 5 be arranged on connect on disk 4, the material of cylinder skin 6 be high strength steel, eradicated traditional structure roller because Cylinder skin and the cylinder skin welding stress and weld defect for connecing the girth welding of disk and being likely to result in, improve roller bearing capacity, it is to avoid cylinder Skin tears accident, and can as changing automobile tire Replacement and Repair rapid wear cylinder skin and clad, it is whole without changing Individual roller, so spare part cost of use can be greatlyd save.

The preferable feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model Sharp scope, the equivalence changes that all utilization the utility model specifications and its accompanying drawing content are made, is both contained in of the present utility model Within interest field.
