Description
Technical field
The utility model relates to a kind of belt deviation correcting device, specifically is a kind of axial center type deviation regulating idler, is mainly used in the belt tuningout of various band conveyors.
Background technology
For a long time, in China band conveyor field, the existing mechanical sensing deviation correcting device that the belt tuningout is all adopted vertical lever principle.Since be subjected to technical limitation, this traditional deviation correcting device inefficiency, and the tuningout function lags behind, and is big to the belt wearing and tearing in the long-term operation process, torn phenomenon so that the belt edge occurs by worn-off.The effect of its correction is undesirable, can not make the very fast recovery track of belt, even the situation that belt disengaging carrying roller is run away occurs.Simultaneously, particularly abominable after domestic existing deviation correcting device moved through the long period at environment, under the unfavorable situation of sealing member, the transmission position usually takes place be blocked extremely, do not have the tuningout effect, also produce counteraction on the contrary.Present home products usually through after the some months operation, promptly needs to tie down with iron wire, influences the total system operation, hinders belt-driving, even can bring a series of adverse consequencess such as damaging conveyer belt.
Summary of the invention
The utility model is is now researched and developed a kind of axial center type deviation regulating idler in order to solve the problem that existing deviation regulating idler is faced, and this deviation regulating idler carries out appropriate design to the carrying roller inner structure, and structure is compact more, the tuningout function well.
The purpose of this utility model realizes by following measure:
A kind of axial center type deviation regulating idler, mainly form by carrying roller 1 and deviation correcting device, it is characterized in that described deviation correcting device integral body is axially set in carrying roller 1 inner chamber, this deviation correcting device comprises swing axle 9, interior rotating casing 5, antifriction-bearing box 6, in being set in, carrying roller 1 outside the rotating casing 5, is provided with antifriction-bearing box 6 between the two; Interior rotating casing 5 is set on the swing axle 9, and forms flexible connection in both middle parts.
Swing axle 9 links to each other by radially being set in both turning cylinders 4 at middle part with interior rotating casing 5.
The center of gravity of deviation regulating idler is positioned on the turning cylinder 4.
The two ends in space are provided with sealed bearings 7 between carrying roller 1 and the interior rotating casing 5.
Both sides are equipped with antifriction-bearing box 6 between carrying roller 1 and the interior rotating casing 5, and antifriction-bearing box 6 lays respectively at the inboard of the sealed bearings 7 at two ends.
Swing axle 9 is the shoulder axle, and the external diameter of the one section shoulder in middle part and the internal diameter of interior rotating casing 5 are suitable.
Carrying roller is a laminar texture, and internal layer is a steel pipe, and skin is (rubber) clad.
The carrying roller both sides are equipped with dust boot.
Dust boot is the little taper rubber case of the big end of an end, and big end is sleeved on the carrying roller outer wall, and small end is sleeved on the swing axle.
The utility model has following advantage compared to existing technology:
Existing deviation correcting device adopts vertical lever principle machinery sensing mode, because a variety of causes does not often have the tuningout effect, also has the problem of damage belt.The utility model does not adopt lever principle through the horizontal deviation regulating idler of changing, and utilizes the swing axle and the turning cylinder at carrying roller center, carries out tuningout according to the belt situation automatically.This kind carrying roller period of service is long, tuningout frequency height, can be in one minute tuningout for several times, belt is remained in the running orbit scope.At the blanking position, can play buffer action especially.Because compact conformation is convenient to conveyer is stepped up various sealing rain-proof equipments, has solved the problem that domestic existing deviation regulating idler produced effectively.
Axial center type deviation regulating idler of the present utility model is that latest domestic type, value of service are higher, a kind of desirable correction deviation correcting device of freedom from repairs, reaches advanced world standards.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, axial center type deviation regulating idler of the present utility model, mainly form by carrying roller 1 and deviation correcting device, deviation correcting device integral body is axially set in carrying roller 1 inner chamber, this deviation correcting device comprises swing axle 9, interior rotating casing 5, antifriction-bearing box 6, sealed bearings 7 (can adopt the labyrinth packing bearing), turning cylinder 4 and dust boot, on the rotating casing 5, be provided with antifriction-bearing box 6 between the two in carrying roller 1 is set in, can do relative motion by antifriction-bearing box 6 at carrying roller 1 and interior rotating casing 5.
Rotating casing 5 is set on the swing axle 9 in of the present utility model, and forms flexible connection in both middle parts.Swing axle 9 is provided with corresponding through hole with interior rotating casing 5 middle parts, and turning cylinder 4 is set in the through hole of swing axle 9, and the through hole on the rotating casing 5 both sides tube walls is fixed by locating dowel pin or nut in passing.The relevant position of corresponding turning cylinder 4 is provided with positioning groove on the carrying roller 1.Turning cylinder 4 two ends are provided with outside thread, use nut screwing clamping behind the shimming respectively.During design, the center of gravity of deviation regulating idler is positioned on the turning cylinder 4, preferably is positioned on the center of turning cylinder 4, like this tuningout better effects if.The two ends of turning cylinder 4 can also be provided with rolling bearing, and are more flexible to guarantee that turning cylinder 4 rotates.
