Abstract
The utility model discloses a carry chain gyration direction roller with waterproof function, including 1 overcoat, 2 endothecas, 2 shields and 1 round pin axle, through vice rotation of big clearance friction that forms, avoided the bearing corrosion card of traditional structure to hinder the problem between overcoat and the endotheca, solved rotary roller normal operation problem under the diuresis environment.
Description
Technical field
The utility model relates to engineering element field, particularly a kind of chain revolution guide roller with water-proof function for chain-linked conveyer.
Background technology
Chain revolution guide roller is the vitals of chain-linked conveyer, and it forms row of rollers by multiple roller along revolution circular arc, makes chain keep arc track to run when horizontal rotation, and can reducing friction resistance.Traditional chain revolution guide roller is made up of overcoat, inner sleeve and ball bearing of main shaft, but at some special stations (as purge chamber) of painting because large water gaging and the direct or indirect spray of cleaning liquid are on revolution guide roller, cause bearing rust, revolution jam, friction aggravation, system cloud gray model is unstable and drive the phenomenons such as overload.Due to by space and environmental limit, also cannot adopt lubrication and seal approach, up to the present never have good solution.
The utility model, in order to overcome above-mentioned defect, has carried out useful improvement.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of chain revolution guide roller with water-proof function for chain-linked conveyer.
To achieve these goals, the utility model have employed following technical scheme:
A kind of chain revolution guide roller with water-proof function for chain-linked conveyer, its special character is: described overcoat and be interiorly enclosed within radial direction and axial direction is free-running fit, Roller Shaft is pressed in above-mentioned part between fixed mount at axial direction, two ends are dustproof cover structure, have running clearance between inner sleeve and overcoat, this programme comprises overcoat, inner sleeve 1, inner sleeve 2, cover of dust 1, cover of dust 2 and bearing pin.
Further, described overcoat adopts No. 45 carbon steel materials, surface hardening process, hardness HRC58-62 °, to reach high hardness and wear resistance requirement.
Further, described inner sleeve adopts copper matrix self-lubricating material, is that a kind of High Performance of inlaying graphite or MoS2 solid lubricant on the matrix of high-tensile strength brass fixes lubrication product, in use, form oil, powder the lubricant deposited, reach excellent lubricating condition.
Further, described cover of dust adopts dead-soft steel one time punching molded, surface blackening process.
The beneficial effects of the utility model: under this revolution roller is applied to many water environments such as application purge chamber, solve the roller jam because bearing rust causes, friction aggravation, run unstable problem, this structure have good lubricity, structure simple, be easy to safeguard, the service life extending roller, the use and maintenance cost reducing equipment.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Fig. 2 is the cutaway view of overcoat.
Fig. 3 is the cutaway view of inner sleeve 1 and inner sleeve 2.
Detailed description of the invention
Below in conjunction with accompanying drawing and enforcement, the utility model is further described.
Embodiment of the present utility model as shown in Figure 1, the utility model is made up of overcoat, inner sleeve 1, inner sleeve 2, cover of dust 1, cover of dust 2 and bearing pin, described overcoat and described in be enclosed within radial and axial for free-running fit, overcoat can be that axle freely rotates with inner sleeve 1 and inner sleeve 2, and inner sleeve 1, inner sleeve 2, cover of dust 1 and cover of dust 2 do not rotate.
The above-mentioned novel pivoting friction of the wide arc gap pair that adopts between overcoat and inner sleeve substitutes traditional bearing arrangement, efficiently avoid the roller jam that corrosion causes, has done actv. trial in the art, solve a production difficult problem, achieve satisfied effect.
