Abstract

Disclosed is a ceramic roller. The utility model discloses a bearing inner ceramic roller which is extensively applied in the belt conveyor in the metallurgy, chemistry and mine industry, comprising an axle (5), a dust-proof lid (4), a bearing (2), a bearing inner seat (6), a clamping ring (3) and a ceramic roller (1). The utility model is characterized in that the bearing inner seats are arranged on the two ends of the ceramic roller (1). Because the bearing inner seat (6) is arranged on the two ends of the ceramic roller (1) in the utility model, the roller will not be eccentric, thereby improving the contact between the conveyor belt and the utility model. No edge running phenomenon will happen by eccentricity caused by the slide ceramic body after running-in for some time.

Description

Carrier roller

Technical field

Ceramic idler in the industries such as the utility model relates to and a kind ofly is widely used in smelting, chemical industry, mine on the belt transporter is sat carrying roller in especially a kind of ceramic bearing.

Technical background

Present carrier roller mainly contains two kinds, a kind of is that the porcelain roller body is cylindrical, another kind is that the porcelain roller body is cydariform, and both include porcelain roller body, mandrel by structures composition, bearing, the dust protecting cap of back-up ring, the latter has alleviated about 15% weight than the former, thus the service life of corresponding prolongation carrying roller, but two kinds of carrier rollers use and all are prone to the phenomenon that conveyor belt skidded, ran the limit, and mostly its reason is holder axle eccentric shaft.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of conveyor belt that prevents to skid, run the limit, thereby improves the carrier roller of whole transport plane work effect just at above-mentioned deficiency.

The utility model comprises the porcelain roller body, axle, and bearing is sat and dust protecting cap in the snap ring, bearing, it is characterized in that having in the bearing in porcelain roller body two ends and sits, and is used for preventing carrying roller off-centre than positive axis.

Seat comes not eccentric than positive axis the utility model in the bearing owing to having at porcelain roller body two ends.So having improved conveyor belt contacts with of the present utility model, even also can not make belt run the limit phenomenon after break-in a period of time owing to porcelain body is smooth.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: sit in 1-porcelain roller body, 2-bearing, 3-snap ring, 4-cover of dust, 5-axle, the 6-bearing

The specific embodiment

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

By refining mud-moulding-drying-sinter technology into, make porcelain rod body (1) with porcelain mud, when moulding, inside groove is processed at the two ends of porcelain roller body (1), be used to put the usefulness of seat (6) in the bearing.Sitting (6) in the bearing sticks with glue solid with porcelain roller (1).In axle, sit and put bearing (2) in (6).Then porcelain roller body (6) is used axle (1), a snap ring (5), cover of dust (2) is assembled by general support roller device method and is got final product.

Claims (1)

1, a kind of carrier roller comprises porcelain roller body (1), axle (5), bearing (2), sit (6) cover of dust (4) and snap ring (3) composition in the bearing, it is characterized in that there is seat (6) blended rubber cementation in the bearing at porcelain roller body (1) two ends, bearing (2) places in the bearing and sits in (6).
