Abstract
A kind of dust-proof carrying roller, comprise roller supporting tube, described roller supporting tube is the cylindrical structure of hollow, is provided with roller carrier shaft in described roller supporting tube, and the two ends of described roller carrier shaft are provided with bearing, and described bearing is provided with end cap, is provided with seal ring between described end cap and bearing.The utility model can prevent the dust at roller carrier shaft and end cover clearance place from entering bearing, and bearing is operated under completely without dust state, and service life is longer.
Description
Technical field
The utility model relates to a kind of dust-proof carrying roller.
Background technology
Belt Conveying equipment is the important component part of continuous and automatic conveying equipment, is widely used in the industries such as mine, harbour, storage, construction machinery and equipment, printing, metallurgy, hydropower, household electrical appliances, food.Carrying roller is the critical component of Belt Conveying equipment.The safe operation directly affecting equipment service life of carrying roller, maintenance cost.
Research shows, affecting carrying roller service life is two large factors, and one is carrying roller roller material, requires roller withstanding corrosion, wear-resisting, self-lubricating, does not damage belt; Two is bearing service life, and affects the factor in bearing service life, and except bearing self resistance to abrasion, the erosion of the many dust of environment for use, aggressive solvent, water all produces significant impact to bearing service life.
Existing carrying roller, bearing-free hermetically-sealed construction, the service life of bearing is short, thus also affects the service life of carrying roller.
Utility model content
Technical problem to be solved in the utility model is, overcomes the deficiency of above-mentioned background technology, provides the dust-proof carrying roller that a kind of service life is longer.
The technical scheme that the utility model solves the employing of its technical matters is, a kind of dust-proof carrying roller, comprise roller supporting tube, described roller supporting tube is the cylindrical structure of hollow, roller carrier shaft is provided with in described roller supporting tube, the two ends of described roller carrier shaft are provided with bearing, and described bearing is provided with end cap, are provided with seal ring between described end cap and bearing.
Further, described end cap is provided with snap ring.
Further, the two ends of described roller carrier shaft are provided with hold down groove, and the hold down groove of described snap ring and roller carrier shaft is fixed.
Further, the inside face at the two ends of described roller supporting tube is provided with hold down groove, and the hold down groove of described snap ring and roller supporting tube is fixed.
Further, described bearing and end cap are for removably connecting.
Compared with prior art, advantage of the present utility model is as follows:
(1) bearing is provided with end cap, is provided with seal ring between end cap and bearing, forms bearing seal structure, prevents the dust at roller carrier shaft and end cover clearance place from entering bearing, and bearing is operated under completely without dust state, and service life is longer.
(2) bearing and end cap are for removably connecting, and by dismounting, regularly add lubricating oil to bearing, keep bearing to run under good lubrication state, extend bearing service life.
(3) end cap is provided with snap ring, and snap ring better can fix end cap, prevents end cap from loosening.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Embodiment 1
With reference to Fig. 1,2,3, the present embodiment comprises roller supporting tube 6, be provided with roller carrier shaft 1 in roller supporting tube 6, roller supporting tube 6 is the cylindrical structure of hollow, and the two ends of roller carrier shaft 1 are provided with bearing 5, bearing 5 is provided with end cap 3, bearing 5 and end cap 3, for removably connecting, by free dismounting, regularly add lubricating oil to bearing, keep bearing lubrication, extend bearing service life; Be provided with seal ring 4 between end cap 3 and bearing 5, form bearing seal structure, prevent the dust at roller carrier shaft and end cover clearance place from entering bearing, bearing is operated under completely without dust state, and service life is longer.
Embodiment 2
With reference to Fig. 4,5,6, the difference of the present embodiment and embodiment 1 is only: end cap 3 is provided with snap ring 2, and the two ends of roller carrier shaft 1 are provided with hold down groove, and snap ring 2 is fixed with the hold down groove of roller carrier shaft 1.Snap ring 2 can better fix end cap 3, prevents end cap 3 from loosening.All the other are with embodiment 1.
Embodiment 3
The difference of the present embodiment and embodiment 1 is only: end cap 3 is provided with snap ring 2, and the inside face at the two ends of roller supporting tube 6 is provided with hold down groove, and snap ring 2 is fixed with the hold down groove of roller supporting tube 6.
Snap ring 2 can better fix end cap 3, prevents end cap 3 from loosening.All the other are with embodiment 1.
Roller supporting tube 6 of the present utility model can be nylon carrying roller cylinder, and service life is metallic roll or common plastics roller more than 5 times, through real-world operation, at least can use more than 5 years.
Those skilled in the art can carry out various modifications and variations to the utility model embodiment; if these amendments and modification are within the scope of the utility model claim and equivalent technologies thereof, then these revise and modification also within protection domain of the present utility model.
The prior art that the content do not described in detail in specification sheets is known to the skilled person.
