Abstract
The utility model provides a rare earth oil-containing alloy nylon composite carrier roller, comprising a center roller shaft and a cylinder at the external surface, a jump ring, a bearing inner sleeve, and a bearing outer are sleeved from inner to outer successively at one end of the roller shaft, two corresponding grooves between the bearing inner sleeve and the bearing outer sleeve are provided with a retainer and several balls, the outer of the bearing inner sleeve and the bearing outer sleeve is successively provided with an inner shielding cover, an outer shielding cover, a sealing ring, an outer sealing assembly, and an outer jump ring, the bottom surface of the inner shielding cover in a close fit with the roller shaft, the inner side surface is provided with upper and lower two projecting ring strips respectively embedded into annular grooves on the bearing outer sleeve and a bearing external side surface, the top surface of the outer shielding cover is in a close fit with the cylinder, the inner side surface of the inner shielding cover is provided with several projecting ring strips embedded into grooves corresponding to the inner side surface of the outer shielding cover. The carrier roller is significantly characterized by light weight, corrosion resistance, good sealing, impact resistance, high speed running, low noise, good wear resistance, etc., and is also advantaged by good temperature tolerance, as well as capability of long-term work in wet, dust, and corrosion environment.
Description
Technical field
The utility model relates to the device on the belt conveyer, specifically, has related to the compound carrying roller of a kind of rare earth oil-containing alloy gold modified nylon.
Background technology
Belt conveyer is comparatively extensive in factories and miness conveying material at present, and the quality of critical component carrying roller directly has influence on the running quality of equipment.Domestic carrying roller commonly used is divided into three kinds of common carrying rollers, full nylon carrying roller, carrier roller by material.Common carrying roller (except that the seal ring material was nylon or plastics, other parts were steel matter) is withstanding corrosion, unreliable, the incompatibility harsh environment of sealing not; And the steel bearing that adopts, meet behind the dirt bondedly easily, even stuckly do not operate, had a strong impact on production.Full nylon carrying roller intensity is low, and radial runout is big, the spindle nose easy fracture.And carrier roller is difficult for processing, running resistance is big.For overcoming the above problems, prior art fails to overcome fully the steel carrying roller existing defective of working in moist dust, corrosive environment.
Summary of the invention
The purpose of this utility model be to provide a kind of in light weight, cost is low, withstanding corrosion, shock resistance, good airproof performance, high-speed cruising noise are low, uses sticking dust, little to the adhesive tape wearing and tearing, the compound carrying roller of rare earth oil-containing alloy gold nylon that operation life is long.
The technical solution of the utility model is: a kind of rare earth oil-containing alloy gold nylon closes carrying roller, it comprises the roll shaft at center and the cylindrical shell of outside face, in an end of roll shaft to outside be arranged with interior jump ring successively, bearing inner sleeve and bearing outside, be placed with retainer and plurality of balls in the corresponding groove of twice between bearing inner sleeve and bearing outside, be followed successively by interior door outside bearing inner sleeve and the bearing outside, outer door and seal ring, exterior seal assembly and outer jump ring, mainly be interior door bottom surface and roll shaft flush fit, its medial surface have up and down two bulge loop bars and respectively with the annular groove that embeds on bearing outside and the bearing lateral surface, outer door end face and simple flush fit, interior door medial surface are provided with some bulge loop bars and embed in the corresponding groove of outer door medial surface.Bulge loop bar on the interior door medial surface is no less than 2.The spacing that 5-10 ㎜ is arranged between outer block face and outer door medial surface.
The beneficial effects of the utility model are: structure of the present utility model utilizes the interior door of closed chamber formula and outer door to cooperate, carry out the bearing chamber sealing, the outside exterior seal assembly location of adopting, rubber seal has been installed again in the exterior seal assembly has carried out contact-type seal, thereby make its sealing property more superior, it is low to have a noise, and rotational resistance is little, characteristics such as it is steady to turn round, be 2.5 ~ 3.5 times of common carrying roller service life.This carrying roller has heavy high resistance to abrasion and ultralow friction coefficient, and superpower not adhesive capacity can prolong 1-2 times of belt service lifes.Distinguishing features such as that this carrying roller has is in light weight, withstanding corrosion, good airproof performance, shock resistance, high-speed operation, noise is low, resistance to abrasion is good, and temperature tolerance is good, can be in humidity, dust, the medium-term and long-term work of corrosive environment.
Description of drawings
Accompanying drawing 1 is the utility model structural representation (partly cuing open).
The specific embodiment
One group of bearing has been shown in the accompanying drawing 1.This carrying roller comprises the cylindrical shell 10 and the roll shaft 12 that is arranged in the cylindrical shell 10, jump ring 11, bearing inner sleeve 9 and bearing outside 7, interior door 5, outer door 4, rubber seal 3, exterior seal assembly 2, outer jump ring 1 in an end of roll shaft 12 from inside to outside has successively of outside face.Bearing inner sleeve 9 peripheries and bearing outside 7 inner headed faces respectively have the corresponding ball grooves of twice, are placed with plurality of balls 8 in the ball grooves, have on retainer 6 and ball 8 the same number of ball holes.Interior door 5 bottom surfaces and roll shaft 12 flush fits prevent bearing inner sleeve 9 end float misalignments.Interior door 5 medial surface upper and lower settings have two bulge loop bars, embed respectively in the concave ring groove on bearing inner sleeve 9, bearing outside 7 lateral surfaces.Door 5 lateral surfaces are provided with plural bulge loop bar simultaneously, embed in the concave ring groove on outer door 4 medial surfaces 4 spacings that 5-10 ㎜ is arranged of interior door 5 lateral surfaces and outer door.Outer door 4 closely cooperates with cylindrical shell 10 inwalls, forms the sealing swivel.The spacing that 5-10 ㎜ is arranged between outer block face and outer door medial surface.Door 4 arranged outside have exterior seal assembly 2 outside, are provided with rubber seal 3 between outer door 4 and the exterior seal assembly 2, and seal ring 3 is set in the outer wall of exterior seal assembly 2, and exterior seal assembly 2 arranged outside have outer jump ring 1.The two ends of roll shaft 12 are provided with roller shell axle 13.Described roller carrier shaft adopts the 35# steel to make, and jump ring and ball are made by steel material.Carrying roller cylinder, bearing inner sleeve, overcoat, interior door, outer door, exterior seal assembly, the carrying roller sleeve is made by rare earth oil-containing alloy gold nylon composite materials.
