Abstract

The utility model disclose a spiral roller which has a reasonable structure, high transmission efficiency, a good using effect and long service life, and is applicable to various material conveying occasions. The spiral roller comprises a shaft core and a shaft sleeve wherein spiral bodies the shaft core and the shaft sleeve are connected with each other inside and outside at an interval, and the shaft sleeve comprises a plurality of long rod bodies arranged around the shaft core.

Description

Spiral roller bearing

Technical field

The utility model relates to a kind of feedway, relates in particular to a kind of spiral roller bearing that can be used for device for transporting objects.

Background technology

Roller bearing or cylinder be as a kind of drive disk assembly, simple in structure with it, maintenance maintenance simple, convenient and be widely used, as be used for the transmission supporting rolling shaft of various belt conveyors, the Power Available Shaft of drive belt is used for the pair roller roller bearing of opposite-grinding device etc.But this drive disk assembly be used for that transfer ratio is dry, during the material that do not have viscosity more satisfactory, the transmission efficiency of its result of use than higher; But when be used for comparison moist, mass transport field that viscosity ratio is bigger or that particle is harder is fashionable; Its defective is just more outstanding, occurs easily that material is bonded on the belt, on the roller bearing; This makes belt conveyor produce distortion on the one hand easily and influences service life, when serious production can't be carried out, and maintenance and repair is relatively more difficult on the other hand, and work capacity is big, and labour intensity is big, also causes the waste of material easily.

The utility model content

The purpose of the utility model is the deficiency that exists to prior art, and a kind of spiral roller bearing is provided, and this spiral roller bearing is rational in infrastructure, and driving efficiency is high, and result of use is good, and long service life is applicable to that various materials transmit occasion.

The technical scheme of the utility model comprises axis body, and said axis body comprises that being provided with spacing, interconnective axle core and axle sleeve each other constitutes.

Be provided with some blocks of a conveyor screw or space between said axle core and the axle sleeve along its length, being positioned at relatively, the said axle core and the axle sleeve in the outside interconnect through this conveyor screw or block.

Said axle sleeve is provided with some through slots or hole.

Said axle sleeve is made up of the periphery that some bars, plate or block space are set around said axle core.

Its outside wall surface of said bar, plate or block is curved.

The roller bearing of the utility model adopts the inside and outside double-layer structure of axle core, axle sleeve; Be equivalent to a hollow axis body; And the hollow cavity of axis body makes roller bearing when work through the through slot on the axle sleeve or the outside UNICOM of hole and axis body, when material falls between driving band and the roller bearing, can get in the hollow cavity of axis body through groove or hole; Because hollow cavity constitutes a helical flow path through conveyor screw; The material that make to get into the axis body hollow cavity is excessive to the both ends or one end of roller bearing through helical flow path, so just can avoid falling into the material aggregately stacked between driving band and the axis body surface and damages driving band, roller bearing etc., to such an extent as to influence the normal operation of device.The making intensity of the roller bearing of the utility model requires low relatively, and then makes that the making requirement of strength of driving band is low, and can reduce the needed power of whole feedway.Practice thrift the energy to a certain extent, improved production efficiency.

Description of drawings

Fig. 1 is the utility model one example structure scheme drawing.Fig. 2 is the structural representation of axle core and conveyor screw (plate) among Fig. 1.Fig. 3 is another example structure scheme drawing of the utility model.

The specific embodiment

Existing through embodiment and combine accompanying drawing that the utility model is described further.Like Fig. 1, shown in 2, axis body 7 constitutes by axle core 1 with the axle sleeve 3 that a spacing is sheathed on a core 1 periphery.Its length direction solderless wrapped connection of 1 periphery wall upper edge of axle core has a conveyor screw (plate) 2; Axle sleeve 3 is made up of through the body of rod 3a that spiral plate 2 is fixedly connected on the core 1 around axle core 1 periphery apart from 3c some spaces one; The internal perisporium of axle sleeve 3 constitutes an inner chamber with the periphery wall of axle core 1, and this inner chamber constitutes a helical flow path 4 by spiral plate 2; Axis body 7 is outside through spacing 3c and helical flow path 4 UNICOMs between each rectangular body of rod 3a, makes the material that is attached to axis body 7 outside faces get into helical flow path 4 from spacing 3c, overflows from axis body 7 ends again.

Rectangular body of rod 3a can be for the steel bar of the corresponding curved wall of circumference radian of its wall and axis body 7 in the outer part, or be round bar.

The length of axle core 1 is equal to or greater than the corresponding helix length of conveyor screw (plate) 2, and conveyor screw (plate) 2 is the spacing between the internal perisporium face of periphery wall and axle sleeve 3 of a core 1 at the height of the radial direction of axis body 7, and is the degree of depth of helical flow path 4.The size of the spacing 3c that forms between the cross-sectional area of the pitch of spiral plate 2, helical flow path 4 and each body of rod 3a can be confirmed according to the character (material viscosity degree and flowing power etc.) of material.

Another embodiment of the utility model is as shown in Figure 3, and axle sleeve 3 constitutes through spiral plate 2 fixedly sleeved bodys 8 in axle core 1 outer circumferential side by one, be arranged with on the body 8 some UNICOMs in body 8 inside and outsides, be microscler groove or hole 3b along body 8 length directions.All the other structures and the foregoing description are together.

Some plate bodies that the conveyor screw of the utility model can use the space to be distributed on the core perisporium substitute.

Claims
