Description

Anti-channeling bearing seat of bearing roller with optimize location packaging structure

Technical Field

The utility model relates to a technique in conveyer field specifically is a prevent scurrying bearing roller bearing frame with optimize location packaging structure.

Background

Belt conveyors are widely used, and a plurality of carrier rollers are generally arranged below a conveyor belt for supporting, and the conveyor belt runs and is in contact friction with the carrier rollers, so that the carrier rollers are caused to rotate. The carrier roller bears the carried articles on the conveyor belt for a long time, so that the carrier roller is a part with the largest use amount and the highest replacement frequency in the belt conveyor. The existing carrier roller seal mostly adopts axial non-contact labyrinth seal, and the structure has the defects that: errors exist in machining and assembling, and the rotary annular teeth are caused in the working process of the carrier roller; the relative clearance in the groove is not uniformly distributed; the carrier rollers are abraded mutually, and especially in places with large gaps and easy entry of pollutants, the abrasion is more serious; the waterproof performance is poor. For this reason, contact lip seals have been developed in belt conveyor idler designs in place of labyrinth seals. The sealing strip of lip seal is made by polyurethane material, and is sealed to have good water-proof effects than labyrinth, nevertheless because polyurethane material's hardness is low, the lip contact seal face's coefficient of friction is big, and lip seal's bearing roller resistance is sealed big than labyrinth, and the wearability can not satisfy the life requirement of bearing roller simultaneously.

The search of the prior art shows that Chinese patent document publication No. CN201545478U, published 2010-08-11 discloses a sealing carrier roller structure, and the technical scheme solves the sealing problem of the carrier roller. However, in practice it has been found that in the case of such seal idler designs, the problem exists that the bearing blocks are prone to escaping from the idler shell, thereby resulting in a reduction in the service life of the installation. The reason for this problem is that: because the roller skin 1 produces alternating axial force with the friction of conveyer belt in the in-service process, this alternating axial force produces the repeated impact effect to bearing frame 3, and roller skin 1 both ends are the straight flange, and the mode of connection with this bearing frame 3 of bearing roller is the screw. Because the axial force is repeatedly impacted on the bearing seat 3, the screw is loosened and cannot form effective connection, and the bearing seat is easy to jump out of the carrier roller.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it is not enough to the above-mentioned that prior art exists, provide one kind and have the anti-channeling bearing roller bearing frame who optimizes location packaging structure, can effectively prevent the bearing roller bearing frame drunkenness, extension fixture long service life, be convenient for assembly and maintenance.

The utility model discloses a realize through following technical scheme:

the utility model discloses a: roller skin, bearing roller axle, bearing frame, bearing, end cover, thrust adjustment mechanism, sealing mechanism, location structure and packaging structure, wherein: the bearing support shaft is arranged in the center of the roller shell, the bearing seat is sleeved inside the roller shell, the bearing, the sealing mechanism, the thrust adjusting mechanism and the end cover are sequentially sleeved inside the bearing seat from inside to outside by taking the bearing support shaft as a center, the positioning structure is arranged inside the bearing support shaft and the roller shell, and the packaging structure is arranged at the end part of the roller shell.

The positioning structure is a first positioning step at the contact part of the roller shell and the end part of the bearing seat, and a clamp spring or a second positioning step at the sleeve joint part of the bearing and the roller carrier shaft.

The packaging structure is characterized in that a curled edge is arranged at the end part of the roller shell to package the bearing seat.

Technical effects

Compared with the prior art, the utility model discloses structure based on prior art improves, and simple structure and low cost can effectively avoid the problem of bearing frame drunkenness, and the life of extension fixture is convenient for assemble and maintain.

FIG. 2 is a schematic view of the bearing housing of the present invention prior to installation in a drum skin;

FIG. 3 is a schematic view of the bearing housing of the present invention after it has been installed in the drum skin;

in the figure: the roller comprises a roller shell 1, a roller carrier shaft 2, a clamp spring 3, a positioning structure 4, a bearing seat 5, a bearing 6, a packaging structure 7, an end cover 8, a thrust adjusting mechanism 9, a sealing mechanism 10, a first positioning step 11 and a second positioning step 12.

Detailed Description

As shown in fig. 1, the present embodiment includes: roller skin 1, bearing axle 2, bearing frame 5, bearing 6, end cover 8, thrust adjustment mechanism 9, sealing mechanism 10, location structure 4 and packaging structure 7, wherein: bearing roller shaft 2 sets up in roller skin 1 central authorities, and bearing frame 5 cup joints inside roller skin 1, and bearing frame 5 is inside cup joints bearing 6, sealing mechanism 10, thrust adjustment mechanism 9 and end cover 8 from inside to outside in proper order with bearing roller shaft 2 as the center, and location structure 4 sets up in the inside of bearing roller shaft 2 and roller skin 1, and packaging structure 7 sets up in the tip of roller skin 1.

As shown in fig. 2 and fig. 3, the positioning structure 4 is a first positioning step 11 at the contact position of the roller leather 1 and the inner end surface of the bearing seat 5, and a clamp spring 3 or a second positioning step 12 at the sleeve joint position of the bearing 6 in the bearing seat 5 and the carrier roller shaft 2.

The packaging structure 7 is used for arranging a curled edge at the end part of the roller shell 1 so as to package the bearing seat 5.

The thickness of the end curling edge of the roller leather 1 is 0.5-5.0 mm, and the radius of the curling edge is 1.0-10.0 mm.

The device realizes the positioning and packaging of the carrier roller bearing seat in the following way: as shown in fig. 2, before the bearing seat 5 is installed in the roller shell 1, the bearing seat 5 is arranged in the roller shell 1 to a position from the first positioning step 11, the bearing 6 in the bearing seat 5 is sleeved with the clamp spring 3 or the second positioning step 12, the position of the bearing seat 5 is determined, and at the moment, the distance between the outer end face of the bearing seat 5 and the bottom face of the roller shell 1 is 1.0-10.0 mm. As shown in figure 3, the end of the roller shell 1 is curled, the radius of the curled edge is 1.0-10.0 mm, and at this time, the bearing seat 5 is packaged in the roller shell 1.

Compared with the existing sealing carrier roller structure, the roller shell inner part positioning device has the advantages that the first positioning step 11 is additionally arranged in the roller shell inner part, the bearing seat is positioned, and the movement of the existing sealing carrier roller structure towards the inner part of the roller shell under the action of axial force is effectively limited. Simultaneously, newly-increased packaging structure 7 encapsulation bearing frame 5 is inside the roller skin, can play effective restriction current sealed bearing roller structure moves to the outside leap of roller skin under the axial force effect. Through actual on-line comparison, the structure of the invention completely solves the problem that the bearing seat of the existing sealing carrier roller structure is easy to escape from the roller leather, and greatly improves the service life and the quality stability of the carrier roller.

The foregoing embodiments may be modified in many different ways by those skilled in the art without departing from the spirit and scope of the invention, which is defined by the appended claims and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
