Abstract
The utility model relates to a novel roller for a belt conveyer, which is characterized in that a bear seat is not used for fixing a bearing, but an outer cover is matched with an outer ring of the bearing and a full bobbin, and an inner cover is matched with an inner ring of the bearing and the bearing. The stressed state of a cantilever of the bearing is improved, and the utility model has the advantages of easy fabrication. Another characteristic of the utility model is that an adjustable sealing ring which lengthens the path of a labyrinth is adopted, which improves the working condition of the bearing, extends the service life of the roller four times and reduces the cost 21%.
Description
What the utility model was related is the belt conveyer carrying roller, is made up of the bearing seat and the seal ring of bobbin, axle, symmetric arrangement usually.
Current domestic and international belt conveyer carrying roller, all be with bearing installation on bearing seat, again bearing seat is installed on the bobbin.Carrying roller as belt conveyers such as the TD75 type of China, the GL type of Japan, the ML type of Germany, gondola PS types.Because bearing seat is in the cantilever force situation with axle, make the bobbin rotational resistance big and two ends axis hole right alignment is not high, the carrying roller not working.In addition, bearing felt is bad and can not adjust.
The purpose of this utility model is that carrying roller force-bearing situation and sealing are improved, and its life-span is prolonged, and anufacturability is good, and cost descends.
The utility model is to achieve the above object by the following method, removes original bearing seat, adds overcoat between outer race and bobbin inner face, and this overcoat has positioning action concurrently; Overlap between bearing inner ring and axle, adding and locate with back-up ring.The labyrinth seal circle of the lengthening distance that the sealing of bearing is then formed by exterior seal ring and inner seal ring and adjustable seal ring are realized.Because two bearings is to implement to install, and is stable, because installation overcoat position, bobbin two ends is a time processing, improved the right alignment of two bearings again, the carrying roller resistance is reduced, gone slick.Adopt the labyrinth seal circle of lengthening distance to make extraneous foreign matter be difficult for entering in the bearing, seal ring reaches adjustable contact force by the adjustable seal ring that is enclosed within on the axle.Owing to taked above-mentioned measure, make manufacturing process simple, carrying roller running odd jobs, the life-span improves, and cost descends.
The utility model compared with prior art has following advantage:
1, change the practicable installation of interior overcoat into owing to cancelled the installation of bearing cantilever, thereby changed the shaft strength situation, because bobbin two stomidiums are processed simultaneously, improved the right alignment in hole, this just makes the carrying roller resistance little, and rotation is flexible, has improved the life-span.
2, owing to adopted the labyrinth seal circle and the adjustable seal ring of long distance, make sealing more effective, this has all improved preventing that foreign matter from invading with maintenance is lubricated, thus the life-span of having improved bearing.
3, the interior cover of Jia Ruing, overcoat can batch manufacturings, accomplish the precision unanimity, guarantee to cooperate, and reduced cost.
In a word, owing to taked above measure, make the carrying roller life-span improve three times, cost descends 21%.Describe below in conjunction with accompanying drawing: the 1st, adjustable seal ring, its lock ring carry out axially adjustable moving on axle.The 2nd, seal cover cap.3 exterior seal rings.4 inner seal rings.5 overcoats.6 bearings.7 back-up rings.Cover in 8.9.10 bobbins.
Embodiment of the present utility model is described as follows: at first section of a pipe two ends inner face is processed into the size that matches with overcoat 5, overcoat 5 is packed into.The overcoat 5 of again bearing 6 being packed into, cover 8 in axle 9 one ends are packed into, and match the inner seal ring 4 of packing into successively, exterior seal ring 3, seal cover cap 2 and adjustable seal ring 1 with bearing 6.Install the other end of carrying roller by above-mentioned order, adjust the leak free degree of tightness.So far, no bearing seat carrying roller assembly and adjustment is finished.
Claims (1)
1, a kind of belt conveyer carrying roller that belongs to, comprise bobbin, axle and seal ring, it is characterized in that it is no bearing seat carrying roller, between bearing (6) outer shroud and bobbin (10) inner face, an overcoat (5) is arranged, cover (8) and fixing with back-up ring (7) and axle (9) in one is arranged between ring and the axle (9) in bearing (6), and seal ring is made up of the labyrinth seal circle and the adjustable seal ring (1) of the lengthening distance that exterior seal ring (3) and inner seal ring (4) are formed.
