Abstract
The utility model discloses a water/dust-proof supporting roller bearing seat, comprising a seat body (1), a bearing (2) and a sealing body (3), wherein the seat body and the bearing are integrally formed in moulds, at least one sealing annular groove (8) is formed on the seat body, the seat body is internally provided with the sealing body (3) which is provided with a sealing ring (6) corresponding to the sealing annular groove on the seat body in quantity and position, the sealing ring on the sealing body is embedded into the sealing annular groove on the seat body so that a labyrinth seal is formed between the seat body and the sealing body, and the seat body is internally provided with an end cover body (5). The water/dust-proof supporting roller bearing seat not only simplifies the manufacturing procedures of bearing seat and saves the manufacturing cost of supporting roller, but also reduces precision deviation caused by the assembly of the seat body and the bearing and enhances the concentricity of the bearing seat and the roller body, in addition, the bearing seat can be sealed reliably without the additional assembly of sealing rings, thereby saving the material, facilitating the installation better, enhancing the operating performance of the supporting roller, prolonging the operating period of the supporting roller, reducing the operating cost of belt conveyor and raising the working efficiency of belt conveyor.
Description
Technical field
The utility model relates to idler for belt conveyer, especially relates to water proof and dust proof roller carrier shaft bearing.
Background technology
As everyone knows, band conveyor is that a kind of operational throughput is big, and the transmission efficiency height carries cost low, and have free from dust, noise low, be not subjected to effects limit such as topography and geomorphology, climate and environment, can realize load transfer device remote, that long-time continuous is carried.Carrying roller is important and crucial parts in band conveyor, and the carrying roller serviceability is directly connected to the transmission efficiency and the job costs of band conveyor.The factor that influences carrying roller serviceability and service life mainly is the waterproof and dustproof grade protection of roller carrier shaft bearing to bearing except that the roll body wearing and tearing.At present the roller carrier shaft bearing mostly adopts very easy iron cover, generally with the welding of iron cover or be bonded in the roll body two ends, again with bearing fixing in easy bearing seat, load onto rotating shaft after, again seal ring and seal cover cap are fixed on the roll body two ends.Not only manufacturing errors is big for existing bearing seat, installation is also cumbersome, expense is higher, and the back concentricity is installed and leak tightness not high, will occur bearing seizure easily during the carrying roller running, intake, advance the phenomenon of dust, cause the carrying roller operating load to increase, bearing failure, both increase energy consumption, reduced the carrying roller serviceability again, shortened the service life of carrying roller, influence the band conveyor work efficiency, increase the band conveyor job costs.
The utility model content
Problem at above-mentioned prior art middle idler roller bearing seat existence; the utility model provides a kind of not only manufacturing and easy for installation; and can improve the carrying roller serviceability; effectively dustproof and waterproof is protected bearing; prolong carrying roller service life; reduce the band conveyor job costs, improve the water proof and dust proof roller carrier shaft bearing of band conveyor work efficiency.
The technical scheme that the technical problems to be solved in the utility model is taked is: described water proof and dust proof roller carrier shaft bearing is fitted in the carrying roller roll body two ends, it comprises pedestal, bearing and sealing member, described pedestal and bearing whole manufacturing the in mould forms, design forms at least one closure gasket groove on pedestal, in pedestal, be provided with sealing member, described sealing member be provided with pedestal on the corresponding seal ring of closure gasket groove quantity and position, seal ring on the described sealing member and the closure gasket groove on the pedestal embed mutually, make between pedestal and the sealing member and form labyrinth seal, in pedestal, be provided with end cover body.
Bearing seat is easy for installation in the carrying roller roll body, bonding is fixing more solid and reliable in order to make, and is interval with link slot on pedestal and outside face that the carrying roller roll body matches.
For alleviating pedestal weight, reduce the pedestal distortion, being convenient to the pedestal manufacturing, on pedestal, be interval with lightening hole, described lightening hole can be circular hole, also can be the hole of square hole, waist shaped hole or other shape.
Described closure gasket groove cross-sectional plane is square, also can be V-arrangement, circular arc or trapezoidal.
The utility model is made integral body owing to will have the pedestal and the bearing of closure gasket groove, thereby not only simplified bearing seat Fabrication procedure, saved the carrying roller manufacturing cost, and reduced the equipped accuracy error that brings of pedestal and bearing, improved the concentricity of bearing seat and roll body, simultaneously owing to carry closure gasket groove on the pedestal, utilize seal ring and the closure gasket groove on the pedestal on the sealing member to embed formation labyrinth seal mutually, add the water proof and dust proof end cover body is housed, do not need in addition equipped seal ring, just can make bearing seat realize positiver sealing, save material, install more convenient, therefore improved the carrying roller serviceability, prolong the carrying roller work life, reduced the band conveyor job costs, improved the band conveyor work efficiency.
Description of drawings
Fig. 1 is a plan structure scheme drawing of the present utility model,
Fig. 2 is the A-A sectional structure scheme drawing of Fig. 1.
The specific embodiment
In Fig. 1 and Fig. 2, described roller carrier shaft bearing comprises the pedestal 1 of plastics, the sealing member 3 of bearing 2 and plastics, the Integratively manufacturing forms in the mould with being injection-moulded in for described pedestal and bearing, in pedestal, be provided with cross-sectional plane and be the closure gasket groove 8 of square twice annular, in pedestal, be provided with sealing member 3, described sealing member is provided with the corresponding seal ring 6 of closure gasket groove on its position and shape and the pedestal, it between described closure gasket groove and the seal ring little free-running fit, in closure gasket groove, add lithium grease, make between closure gasket groove and the seal ring and be close to sealing, thereby pedestal forms the dustproof and waterproof sealing band of annular between sealing member, just can realize labyrinth seal between pedestal and the sealing member, thereby bearing is effectively isolated with extraneous.Described closure gasket groove also can be arranged to together, three roads or multiple tracks, described closure gasket groove cross-sectional plane also can be V-arrangement, circular arc or trapezoidal, in pedestal, be provided with end cover body 5, described end cover body is positioned at sealing member one side, by the groove in flange on the end cover body 9 and the pedestal (not marking among the figure), end cover body is fixed in the pedestal and forms the concentric locating effect with pedestal, on pedestal and outside face that the carrying roller roll body matches, be interval with link slot 7, link slot quantity can be set according to the pedestal size interval, during the carrying roller assembling, adhesive agent is filled on the pedestal surface and link slot in, pedestal is pressed in the carrying roller roll body two ends again, thereby pedestal can be fixed in the carrying roller roll body.Described link slot can be square, circular arc, V-arrangement, trapezoidal or other shape.Be arranged at intervals with lightening hole 4 on pedestal, described lightening hole can be circular hole, also can be the hole of square hole, waist shaped hole or other shape.
