The technical scheme includes that the sealing device is characterized in that an end cover is fixed to one end of an outer pipe by means of interference fit, a shaft hole is arranged at the center of the end cover, a shaft is mounted in the shaft hole of the end cover through a bearing, one side of the bearing is closely attached to the end cover, a clamp spring and a sealing ring are sequentially arranged on the other side of the bearing and sleeved on the shaft, the section of the sealing ring is M-shaped, a projecting brim matched with the shaft is circumferentially arranged at the center of the sealing ring, a flange is arranged at the outer edge of the sealing ring, a groove is circumferentially arranged on the end face of the end cover, and the flange at the outer edge of the sealing ring is clamped in the groove on the end cover. The high polymer wear resistant sealing device is used for hermetically protecting the end of the carrier roller.
Description
Technical field
The utility model high molecular abrasion-proof carrying roller end seal belongs to the poted assemblies technical field.
Background technology
In the belt transportation industry, belt transporter is the most frequently used transportation means.Carrying roller is the main consumable accessory of ribbon conveyer, and situation about in use damaging is quite serious.In colliery and coal chemical enterprise, this phenomenon is particularly evident, because working environment is more abominable; Include the erosion of water, gas, dust and multiple acid solution, it is quite fast to make that carrying roller damages, the general deficiency of life-span of the steel snub pulley that present most of coal chemical enterprises adopt two months; Statistics is illustrated in the carrying roller of damage; Wherein because the situation of carrying roller surface abrasion accounts for about 50%, other 50% damage is that and the damage of bearing all is basically because its sealing effectiveness is bad because the carrying roller bearings at both ends is damaged and caused carrying roller not rotate and drawn badly; Under the erosion of water, gas, dust and multiple acid solution, lose the due effect of bearing.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is that to put forward a kind of structure of arch ingenious, cooperate compact, the high molecular abrasion-proof carrying roller end seal of good sealing effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: high molecular abrasion-proof carrying roller end seal comprises outer tube, bearing, jump ring, end cap, seal ring and axle; End cap is fixed on an end of outer tube through interference fit, and the end cap center has axis hole, axle through bearing installation in the axis hole of end cap; Said bearing one side is near end cap; Opposite side is disposed with jump ring and seal ring, and jump ring and seal ring all are sleeved on the axle, and the cross section of said seal ring is a M shape; The center of seal ring is provided with the protruding eaves that a circle cooperates with axle; The outward flange of seal ring is provided with flange, and the end face of end cap is provided with a circle groove, and the outer peripheral flange of said seal ring is stuck in the groove on the end cap.
The material of said end cap is a RPP, and end cap and bearing are processed one with injection molding method.
The material of said seal ring is a low density polyethylene (LDPE).
The beneficial effect that the utility model is compared with prior art had is: the cross section of seal ring is a M shape in the utility model; The protruding eaves that a circle cooperates with axle has been designed in the centre; During assembling protruding eaves with the axle on technology groove cooperate; End cap and bearing set are combined into integral molded plastic spare, and are connected with outer tube through interference fit, make sealing effectiveness better.Show that through practice even after the carrying roller surface abrasion can not use, bearings at both ends keeps better state basically.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model high molecular abrasion-proof carrying roller end seal.
Among the figure, 1 is outer tube, and 2 is bearing, and 3 is jump ring, and 4 is end cap, and 5 is seal ring, and 6 is axle, and 7 is protruding eaves, and 8 is flange.
The specific embodiment
As shown in Figure 1, high molecular abrasion-proof carrying roller end seal comprises outer tube 1, bearing 2, jump ring 3, end cap 4, seal ring 5 and axle 6; End cap 4 is fixed on an end of outer tube 1 through interference fit, and end cap 4 centers have axis hole, and axle 6 is installed in the axis hole of end cap 4 through bearing 2; Said bearing 2 one sides are near end cap 4; Opposite side is disposed with jump ring 3 and seal ring 5, and jump ring 3 all is sleeved on the axle 6 with seal ring 5, and the cross section of said seal ring 5 is a M shape; The center of seal ring 5 is provided with the protruding eaves 7 that a circle cooperates with axle 6; The outward flange of seal ring 5 is provided with flange 8, and the end face of end cap 4 is provided with a circle groove, and said seal ring 5 outer peripheral flange 8 are stuck in the groove on the end cap 4.
The material of said end cap 4 is a RPP, and end cap 4 and bearing 2 are processed one with injection molding method.
The material of said seal ring 5 is a low density polyethylene (LDPE).
When the utility model is installed; Earlier end cap 4 and bearing 2 are sleeved on the axle 6, end cap 4 is fixed on an end of outer tube 1 through interference fit, again jump ring 3 is sleeved on fixed type bearing 2 on the axle 6; At last seal ring 5 is sleeved on the axle 6; The cross section of seal ring 5 is M shape, and the protruding eaves 7 at seal ring 5 centers cooperates with the technology groove of axle on 6, and the outward flange of seal ring 5 is stuck in the groove on the end cap 4.
