Abstract

The utility model discloses an idler wheel which is used on a chain belt and tray type conveyor. The idler wheel comprises a support, an idler wheel body and an idler wheel shaft, wherein the idler wheel body is supported on a bearing which is arranged on two sides of steps in the middle of the idler wheel shaft, a sealing gasket and a pressing cover are placed on an end face of a hub of the idler wheel body on the outer side of the bearing, the idler wheel shaft is supported on the support, and an oil cup placed on one end face of the idler wheel shaft can lubricate an inner cavity of the bearing through an oil filler hole in the idler wheel shaft. A single protection edge of the idler wheel plays a role of chain belt guiding so as to prevent security accidents caused by deviation and fracture of a chain belt from happening. The idler wheel is machined and formed by applying of forging and pressing, and the casting defects of casting the idler wheel are avoided. The idler wheel has the advantages of being compact in material texture, impact-resisting, good in toughness and long in service life. A baffling cover is adopted on the end portion of the idler wheel to prevent the problem that the bearing is abraded or clamped due to the fact that foreign matters such as muddy water enter the bearing cavity from happening. The idler wheel is used for supporting the chain belt, the friction between the idler wheel and a chain plate of the chain belt is rolling friction, the phenomenon of operating instability caused by the fact that the abrasion of a moving type idler wheel deviates from a rail is avoided, efficient operation of the chain belt is effectively guaranteed, and the service life of the chain wheel can be prolonged.

Description

A kind of roller

Technical field

The utility model relates to a kind of for the roller on chain belt pellet type conveyer or the rolling-wheel fixed casting machine.

Background technology

In the steel industry iron-making production, pig machine equipment becomes iron block smelting the high temperature liquid iron continuous pouring that, and the iron block that falls is transported to the iron block stack-up-yard by the iron block delivery system and stores, and production and the later stage of being convenient to iron block are used.

Present iron block delivery system has that automobile directly transports, locomotive directly transports and roller moves the rotation apron conveyor.The working process that roller moves the rotation apron conveyor is: the receiving hopper that the iron block that falls from pig machine moves the rotation apron conveyor by fixedly iron block chute and roller is fallen roller and is moved on the supporting plate that rotates apron conveyor, actuator drives drive sprocket device rotates, drive sprocket drives portable chain operation, the chain band supporting plate and is rotated, and the iron block on the supporting plate falls at the drive sprocket setting position.In Cast Iron Production zone hour, need transport out the iron block of producing, then main at present what adopt is that roller moves the rotation apron conveyor, and in use there is following problem in this equipment:

The constructional feature of portable chain is that roller is installed on the chain, and roller clip is in the centre of two carrier bars, and its design space is limited.Because roller need snap in the driving that the drive sprocket gear teeth are realized chain belt, need to reserve certain space between two carrier bars, in carrying the iron block process, the little iron block that sputters is filled in this space easily, and when running to the drive sprocket position, the gear teeth enter this space, push mutually with the little iron block of having filled in, cause carrier bar distortion, even carrier bar broken, caused the generation of conveyer accident.

Because roller moves the chain structure of rotation apron conveyor and limits, driven sprocket also must adopt toothing, after moving a period of time, takes off tooth easily after the chain wear elongation, causes the conveyer can't normal operation.

Summary of the invention

The utility model is intended to solve existing roller and moves the above-mentioned technical matters that the rotation apron conveyor exists in operating mode is used, for chain belt pellet type conveyer provides a kind of safe and reliable roller, significantly result of use and the safety performance of improvement equipment prevent that chain belt pellet type conveyer from causing the generation of safety misadventure because of chain belt sideslip, fracture.

The utility model has adopted following technical scheme:

This roller comprises bearing, roller body and roller shaft; Described roller body is bearing on the set bearing of described roller shaft, and is supported on the described bearing by described roller shaft, and this roller body cylindrical driving surface has the monolateral edge of protecting.

Below be that some improve the optimization technique means in the technical scheme:

The monolateral of described roller body protected along diameter than big 10-30 mm of roller body cylindrical working diameter.

Described roller body adopts forging and pressing machine-shaping.

Described roller body is bearing on the set bearing in described roller shaft intermediate step both sides, and the hub end face is provided with packing seal and gland in the roller body of the described bearing outside.

Described roller shaft one end face is provided with lubricating cup can pass through roller shaft oil hole lubricating bearings inner chamber.

Further, the set oil hole of described roller shaft one end face system is by the straight-through roller axle center of axial line, and the radial direction through hole in connection axle center, to two bearings inner chamber oil injecting lubricating.

Two ends of the bearing of this roller arrange block cover.

Further, described block cover adopts the forging and pressing of 2-5mm steel plate or Sheet Metal Forming Technology moulding.

The beneficial effects of the utility model:

This roller is installed on the roller seat of chain belt pellet type conveyer or rolling-wheel fixed casting machine, because chain belt and roller are friction of rolling.Avoid portable roller because the wearing and tearing offset track causes the phenomenon of fluctuation of service, actv. to guarantee the high efficiency of chain belt pellet type conveyer or rolling-wheel fixed casting machine operation, can prolong chain belt service life.

Roller adopts forging forming, has dense materials, shock-resistant, good toughness, long characteristics of life-span, has avoided the foundry defect of foundry goods roller.The monolateral of roller protected along playing the chain belt directional tagging, can prevent from causing because of chain belt sideslip, fracture the generation of safety misadventure.

Block cover is adopted in two ends of roller, has prevented that effectively impurity such as slime water from entering the generation that bearing bore causes problems such as wear-out of a bearing or locking.

Below in conjunction with accompanying drawing the utility model is described in detail.

Description of drawings

Fig. 1 is the scheme of installation of roller on chain belt pellet type conveyer;

Fig. 2 is the structural representation of roller;

Fig. 3 is that the A of Fig. 2 is to view.

The specific embodiment

Further introduce embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1, this roller is applied on the chain belt pellet type conveyer, frame of conveyer 5 is provided with roller seat 4, roller 3 is installed on the roller seat 4 side by side, and roller 3 is in order to 2 transmissions of rest chain belting, and chain belting 2 is under the driving of drive system, set pallet 1 is in roller 3 motions on the drive chain belting 2, drive roller 3 simultaneously and rotate, remaining the rolling transmission between roller 3 and the chain belting 2, can effectively guarantee the safe operation of chain belt pellet type conveyer.This roller also can be applicable to the chain belt driver of support pig machine on the rolling-wheel fixed casting machine.
