The specific embodiment
Carrying roller of the present utility model, for belt conveyer, as shown in Figure 1, is mainly comprised of parts such as roll body 1, bearing seat 2, roller carrier shaft 3, bearing 4 and end covers 5.The symmetrical pair of bearing 2 of installing in two ends of roll body 1, roller carrier shaft 3 is located in the center of roll body, and roller carrier shaft 3, bearing 4 and end cover 5 are arranged in the mounting hole of bearing seat 2.
As illustrated in fig. 1 and 2, the mounting hole of bearing seat 2 comprises: (shown in figure, being right-to-left) arranges successively from inside to outside stepped hole 2a, circular hole 2b and round platform hole 2c, circular hole 2b is communicated with stepped hole 2a and round platform hole 2c.Wherein, bearing seat 2 has an ennation 21 radially, and radially ennation 21 is that bearing seat 2 radially extends and forms towards roller carrier shaft 3, and radially the axial end that stretches to roller carrier shaft 3 of ennation 21 surrounds circular hole 2b.
Roll body is mainly used in supporting belt and rotates under the drive of load-transfer device, roll body is when rotating around roller carrier shaft, can drive and rotate together with its close-fitting parts, for preventing that these parts from axial motion occurring when the High Rotation Speed, and then affecting sealing effectiveness, the utility model designs position limiting structure when assembling adjacent parts.
Bearing seat 2 is spacing to be assemblied on roll body 1, and as shown in Figure 1, the utility model is symmetrically arranged with ladder knock hole 11 at the two ends of roll body, and bearing seat 2 is arranged in ladder knock hole 11.Concrete, as illustrated in fig. 1 and 2, one end of bearing seat 2 and the ladder close-fitting that is used to form ladder knock hole 11, the other end of bearing seat 2 has wedge-shaped bead 22, wedge-shaped bead 22 is pressed on the annular end face of roll body 1, roll body of the present utility model and bearing seat adopt High molecular material to make, and the face that is in contact with one another of roll body and bearing seat sticks together.Due to roll body and bearing seat employing High molecular material, in use can better resist foreign impacts power, resistant to corrosion better effects if, increase the service life.
In the spacing space being assemblied between bearing seat 2 and roller carrier shaft 3 of bearing 4.As shown in Figure 1, roller carrier shaft 3 has axle head step 31, axle head step 31 be positioned at bearing seat 2 right-hand member and with step 23 combineds action that form stepped hole 2a, apply axial application force in opposite directions to bearing 4, for the bearing 4 that prevents from being arranged in stepped hole 2a, there is axial motion, thereby make stable being assemblied in stepped hole 2a of bearing 4.
As shown in Figure 1, the utility model also arranges sealing shelves card 10 in the left side of end cover 5, prevent end cover 5 axial motions, and sealing shelves card 10 is arranged in the mounting groove of offering on roller carrier shaft.
The utility model forms labyrinth seal structure by bearing seat 2 and end cover 5, for bearing 4 is sealed.
Concrete structure is described below:
As shown in figs. 1 and 3, end cover 5 comprises: inner ring body 51, and one end of this inner ring body 51 vertically inwardly (in figure for to the right) extends in stepped hole, and extends to one end and the bearing inner ring close-fitting of the inner ring body in stepped hole 2a; Outer ring body 52, it is interior and parallel with inner ring body that this outer ring body 52 is arranged on round platform hole 2c, and one end of outer ring body 52 extends inward into the radially radial outer end face of ennation 21 vertically; The end cap plane 53 that the other end of inner ring body and outer ring body is connected.During installation, make radially ennation 21 respectively with outer ring body 51 and inner ring body 52 close contacts, form a seal cavity, make extraneous dust and water can not enter easily sealing space or enter in stepped hole 2a by sealing space.
Radially ennation 21 has vertically to several the first bulge loops 24 separately that extend in seal cavity, end cap plane 5 has vertically to several the second bulge loops 54 separately that extend in seal cavity, several the second bulge loops and several the first bulge loop formation labyrinth seal structure of mutually pegging graft.The utility model utilizes bearing seat itself as a part for hermetically-sealed construction, makes compact conformation, and sealing effectiveness is better.The first bulge loop 24 in figure in embodiment has two, and the second bulge loop 54 has one, can select according to actual needs the quantity of the second bulge loop and the first bulge loop.Preferably, in the gap of the second bulge loop and the first bulge loop, add lubricating oil, play on the one hand the effect of sealing, can reduce friction drag on the one hand.
In seal cavity, be also provided with Sealing shield ring 6, Sealing shield ring 6 and bearing seat 2 interference fit.
During assembling, inner ring body 51 and roller carrier shaft 3 interference fit, like this, end cover 5 forms static seal body, keep at work motionless, and Sealing shield ring 6 is fixed together by interference fit with bearing seat 2 and forms dynamic seal body, work natural axis bearing outer-ring rotates with bearing seat together.
As shown in figs. 1 and 4, the cross section of Sealing shield ring 6 is inverted T shape, its radial protrusion having 61 and outer ring body 52 close contacts, and because area of contact is little, the rotational resistance of generation is little.Outer ring body 52 and bearing seat 2 close contacts, form ground floor sealing, plays the ground floor of dust, water to external world and stop; Radial protrusion 61 and outer ring body 52 close contacts, form second layer sealing, plays the second layer of dust, water to external world and stop; Mutually the peg graft labyrinth seal structure that forms of the second bulge loop 54 and the first bulge loop 24 forms the three-layer sealedly, and the 3rd layer that plays dust, water to external world stops.As shown in Figure 1, between bearing seat 2, end cover 5 and bearing 4, surround one for placing the oil groove 7 of lubricating oil, prevent that the lubricating oil in bearing 4 runs off.
End cover of the present utility model and Sealing shield ring are High molecular material, shock resistance, withstanding corrosion.
Although above-mentioned, the utility model is described in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
