Abstract
The utility model discloses a carrier roller device, which comprises a cylinder body (1), a shaft (2) provided with a bearing seat (3), and a sealing sleeve part (4), wherein the shaft (2) is a bright-draw shaft; the sealing sleeve part (4) comprises an inner sealing ring (5) and an outer sealing ring (6); the outer side of the sealing sleeve part (4) is provided with a check ring (7); and a retainer ring (8) is arranged between the shaft (2) and the sealing sleeve part (4). The carrier roller device is ingenious in conception, reasonable in design, good in sealing effect, low in production cost, free from mutual influence between a bearing and the sealing sleeve part.
Description
Technical field
The utility model belongs to the conveying technology field, relates to a kind of support roller device.
Background technology
Carrying roller is to be used for the major part that belt conveyer is supported adhesive tape and material, and the carrying roller running must flexibility and reliability.Reduce the friction force of load-transfer device, the life-span that accounts for the load-transfer device of conveyer total cost more than 25% is played key role with carrying roller.The rotational resistance of carrying roller and service life are the most important measurement indexs of this product.
At present, most carrying roller is made of cylindrical shell, bearing seat, axle, bearing, Seal Kit, back-up ring.Cylindrical shell and bearing seat press-fit or weld, and bearing press mounting goes into to form in the bearing seat rotation relationship of axle and cylindrical shell, and Seal Kit is contained in axle successively and goes up to form the sealing to bearing, by the back-up ring that is contained in axle head bearing and Seal Kit is located at last.This version is because axle adopts stepped shaft version, the processed complex of axle, and consume material, production efficiency is low.Seal Kit is made of four layers of sealed nylon circle and two steel rings, because its version is complicated and the problem of sealing member material, cause roller revolving resistance bigger, particularly after long-time the use, the aging distortion of Seal Kit is serious, cause that carrying roller jam, sealing effectiveness reduce, shorten service life greatly.The back-up ring location that all part location of a whole set of carrying roller are provided with by two ends, this makes the carrying roller assembly precision have relatively high expectations.The seal ring of Seal Kit is an elastic body, because there is certain elastic deformation amount in the crush seal circle, makes the friction between the inner body reduce the carrying roller flexibility of revolution during assembling, can not bear axial impact substantially simultaneously, and axially play is bigger in the assembling back.Cause infrastructure product quality instability, to manufacture yield rate not high.It is bigger that Idler bearing and Seal Kit direct contact make that it influences each other, the axle is worn will influence Seal Kit, and Seal Kit has been broken also can influence bearing, after carrying roller is subjected to external impacts, seal ring even can bearing is stuck causes that the carrying roller jam causes carrying roller along bad.
The utility model content
Goal of the invention of the present utility model is: at having carrying roller productive costs height, bearing and the interactional problem of Seal Kit in the above-mentioned prior art, provide a kind of support roller device.This support roller device is skillfully constructed, reasonable in design, good sealing effect, productive costs is low, does not have between bearing and the Seal Kit to influence each other.
For achieving the above object, the utility model solves the technical scheme that its technical matters adopts and is:
A kind of support roller device, comprise cylindrical shell, be provided with the axle and the Seal Kit of bearing seat, described axle is for drawing optical axis, and described Seal Kit is made of inner seal ring and exterior seal ring, the arranged outside of described Seal Kit has back-up ring, is provided with collar between described axle and the Seal Kit.
As optimal way, described inner seal ring and exterior seal ring are made by the ABS material.
As optimal way, described inner seal ring and exterior seal ring constitute six road labyrinth seal structures.
As optimal way, described cylindrical shell and bearing seat are for being welded to connect.
Axle of the present utility model adopts the optical axis form of drawing, and only needs processing draw-in groove position, need not the periphery processing to axle, so it is easy to process, saves steel, the production efficiency height.Seal Kit constitutes six road labyrinth seal structure forms by inside and outside seal ring, and sealing property is stronger, can prevent effectively that sealing and dust etc. enter bearing.Because have only two obturators, and adopt the microclearance design, the friction between the Seal Kit significantly reduces, roller revolving resistance reduces greatly; Inside and outside sealing ring material adopts the ABS material, and sealing member can be out of shape hardly, wear out, and has improved whole shock resistance of carrying roller and service life.
The utility model adopts the special Spring Clip form of twin-stage, makes its independent operating in that bearing, Seal Kit are effectively separated bearing and Seal Kit in the location, does not have interactional relation, and roller revolving resistance reduces greatly, the jam phenomenon can not occur.Only need after if go wrong to change seal ring or bearing separately, and replacing is convenient.Because positioned apart, each major part does not have mutual positioning relation, the utility model is easy to assembly, constant product quality, and the product shock resistance is strong, and good seal performance reduces conveyer and uses energy consumption obvious.Compared with similar products, the utility model roller revolving resistance only is 30%-50%, and be 2-3 times service life, and productive costs only is 70%-80%, and production efficiency is 3-5 times.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is skillfully constructed, reasonable in design, good sealing effect, productive costs is low, does not have between bearing and the Seal Kit to influence each other.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: 1 cylindrical shell, 2,3 bearing seats, 4 Seal Kits, 5 inner seal rings, 6 exterior seal rings, 7 back-up rings, 8 collars.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment: as shown in Figure 1, a kind of support roller device, comprise cylindrical shell 1, be provided with the axle 2 and Seal Kit 4 of bearing seat 3, described 2 for drawing optical axis, described Seal Kit 4 is made of inner seal ring 5 and exterior seal ring 6, the arranged outside of described Seal Kit 4 has back-up ring 7, is provided with collar 8 between described axle 2 and the Seal Kit 4.
Described inner seal ring 5 and exterior seal ring 6 are made by the ABS material.Described inner seal ring 5 and exterior seal ring (6) constitute six road labyrinth seal structures.Described cylindrical shell 1 and bearing seat 3 are for being welded to connect.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
