Abstract

The utility model relates to a carrier roller for a belt conveyer, which comprises a roller body assembled on a bearing axle with the help of a bearing, wherein, both ends of the roller body made of polymeric compound materials are provided with positioning rabbets. Dish-shaped sealing glands which can encapsulate the bearing and limited clip rings are arranged in the positioning rabbets. The utility model has the advantages of light weight, abrasion resistance, no corrosion, easy manufacture, low production cost, and long service life of the belt conveyor.

Description

Supporting roller for belt conveyer

The utility model relates to a kind of band conveyor idler pulley.

The kind of existing band conveyor is more, and the idler pulley structure in the used bearing set is different.Idler pulley commonly used generally adopts metallic material to make, and promptly adopts the rolled metal section bar processing roll body of casting or all size, and then through machine up, utilizes bearing and bolster to fit together.The processing technology complexity, take a lot of work, take material, manufacturing cost is higher.This metal idler pulley surface easily is bruised, and its surface scratch can damage adhesive tape in equipment running process, when serious even tear adhesive tape, causes industrial accident.The metal idler pulley is under the service conditions of inclement condition, and to relate to power not enough, fragile, not wear-resisting because of it stagnates, and easy-to-rust also influences service life of conveyer.

The purpose of this utility model provides a kind of improved band conveyor idler pulley, its in light weight, wear-resisting, not corrosion, and easily processing can significantly reduce manufacturing cost and improve conveyer service life.

The purpose of this utility model is achieved in that this device comprises and utilizes bearing set to be contained in roll body on the bolster, wherein the polymerized composite materials roll body two ends of making are processed with positioning spigot, and the dish-shaped gland cover and the limit spring back-up ring that can encapsulate bearing are housed in the positioning spigot.

Because the utility model adopts polymerized composite materials to make roll body, on the roll body directly by positioning spigot to bolster and bearing carries out spacing and the encapsulation, so making full use of mechanical characteristics, the physical property of polymerized composite materials reaches that metallic material requires and does not damage the advantage of adhesive tape and roll body that roll body that polymerized composite materials is made is made than metallic material stagnates and relates to the strong performance of power, all the time be in the state of pure rolling in the time of can making this idler pulley work, slip is arranged, adhesive tape easy to wear, damageable disadvantage in effectively having avoided the metal idler pulley relate to rolling when the power difference causes its work because of stagnating.Polymerized composite materials is processed roll body processing not only in light weight, easy, is obviously cut down finished cost, and adopt dish-shaped gland cover and trip ring to encapsulate bearing, compare with the metal roll body, need not be subjected to the restriction of rolling section bar specification, also need not process the special seal end cap assembles, be easy for installation and maintenance, alleviate labor intensity of operating personnel, reduce service expenditure.Therefore, the utility model is compared with the metal idler pulley, can significantly reduce manufacturing cost and improve conveyer service life.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure scheme drawing of the utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.This device comprises roll body 5, bolster 1, bearing 4, dish-shaped gland cover 3, hole limit spring back-up ring 2.Wherein roll body 5 adopts and has applied for the polymerized composite materials one-shot forming of patent of invention.Roll body 5 both ends are processed with positioning spigot.The specification of roll body 5 can be chosen according to actual needs.Overcome the conventional metals idler pulley and choose thick walled steel tube, the disadvantage of welding bearing seat again and being produced by specification.Bolster 4 adopts General Construction.The gland that the encapsulation bearing is used adopts dish-shaped gland cover 3, and its handling ease is easy for installation.During assembling it is pressed in roll body 5 positioning spigots, fixes getting final product again with the hole with limit spring back-up ring 2.Compare with the metal idler pulley, the utility model loading and unloading are quite easy, and main Mechanical and physical property all can reach related standard requirements, so very appearance is applied.

Claims

1, a kind of band conveyor idler pulley, comprise and utilize bearing set to be contained in roll body on the bolster, it is characterized in that: the roll body two ends that polymerized composite materials is made are processed with positioning spigot, and the dish-shaped gland cover and the limit spring back-up ring that can encapsulate bearing are housed in the positioning spigot.
