Background technique
Carrying roller, is the component of the machines such as belt conveyor, respectively stretches out a footstalk at the two ends of cylindrical roller.Carrying roller shape roller, is a kind of new-type rolling body being seated in rectangle or the square raceway of pivoting support, because its likeness in form carrying roller is named.Compared to common cylinder body roller, many advantages such as that carrying roller shape roller has is lightweight, resistance is little, noise is low, highly sensitive and store oil amount is large suitablely adopt in the design of large-size pivoting support.
Model utility content
The purpose of this utility model is to provide a kind of pivoting support carrying roller shape roller, makes up the defect that common cylinder body roller exists.
The technical solution of the utility model is as follows:
A kind of pivoting support carrying roller shape roller, include main cylindrical body and two secondary cylindrical bodys, it is characterized in that: two described secondary cylindrical bodys respectively one are connected to the cylindrical two ends of described master, the cylindrical diameter of described master is greater than two cylindrical diameters of pair, and main cylindrical height accounts for 1/2～2/3 of main cylindrical body and two secondary cylindrical body total heights; Described main cylindrical body and two secondary cylindrical bodys can be horizontal, vertical, oblique or cross arrangement in the rectangle raceway of large-size pivoting support, and main cylindrical diameter equals the length of side of the rectangle raceway minor face at place, main cylindrical body and two cylindrical total heights of pair are slightly less than the length of side on the long limit of rectangle raceway at place.
Described pivoting support carrying roller shape roller, is characterized in that: described main cylindrical body and two secondary cylindrical bodys adopt whole section of Bearing Steel to process.
Described pivoting support carrying roller shape roller, is characterized in that: described large-size pivoting support is the central pest slewing ring more than rolling circle diameter ∮ 2000mm, more than roller diameter ∮ 40mm.
The utility model is compared common cylinder body roller, has the following advantages:
The first, the weight of single carrying roller shape roller only has 2/3～3/4 of common cylinder body roller, and hundreds of rolling elements are added up, and the gross weight alleviating is considerable.
Second, common cylinder body roller is rotation and the power transmission that realizes pivoting support with two tangent line contact raceway walls on cylndrical surface, though carrying roller shape roller has shortened 1/3～1/2 by its tangent line, but the stressed of pivoting support be there is no big harm, and the frictional force of its rolling reduces, reducing noise is relative outstanding with the advantage that sensitivity improves.
The 3rd, rectangle raceway is through Overheating Treatment, and its raceway wall intermediate portion depth of hardening zone is large, hardness is high, and the position at four angles is relatively weak, and carrying roller shape roller is just in time just real keeps away void, has maximally utilised the optimal site of raceway wall.
The 4th, carrying roller shape roller only need be used the intermediate portion of rectangle raceway wall, and chamfering can be established in its position, right angle as far as possible, is conducive to reduce stress and concentrates, and increases the intensity of raceway.
The 5th, it is less that carrying roller shape roller takies the space of raceway, and raceway store oil amount is strengthened, and is conducive to the maintaining of pivoting support and improves working life.
