Abstract

A roller capable of rotating around a shaft and a circumferential direction is characterized in that a plurality of small roller assemblies capable of rotating around a circular ring independently are arranged on a transmission shaft side by side, and the two adjacent small roller assemblies are arranged in a staggered mode at a certain angle, so that the projections of the small roller assemblies on the axial section along the transmission shaft form a complete circle, and when a material moves on the roller along the axial direction, rolling friction force can be obtained.

Description

Roller capable of bidirectionally rotating

Technical Field

The invention belongs to the technical field of mechanical conveying, particularly relates to a roller structure of a roller conveying line, and particularly belongs to a novel roller structure.

Background

The invention relates to a novel roller structure, wherein the existing roller can only axially rotate around a shaft, and if materials need to advance along the axial direction, the materials can only slide on the surface of the roller, so that the sliding friction force generated by the sliding friction can easily scratch the materials and damage the roller structure. In view of this drawback, the present invention provides a roller capable of rotating in both directions. But two-way rotation roller has two kinds of rotations of axial and circumferencial direction, can make the material advance along the axial alright make roller surface rotate around the circumferencial direction, just so can reduce the frictional force on roller and material surface, reduce the fish tail material and the thing of damaging the roller and take place, especially when the material is big more, the advantage is more obvious.

Disclosure of Invention

But two-way rotation roller mainly is the problem that the frictional force is big when solving the material and advancing along the axial, reduces the fish tail material and harms the thing of roller and takes place, makes the material produce rolling friction when advancing along the axial, reduces frictional force greatly, also reduces energy loss when both having protected material and roller.

The technical scheme of the invention is as follows: a row of small rollers capable of rotating is arranged on a rotatable transmission shaft along the axial direction, the small rollers are combined into rings with the same size through a specific bracket, the rings are called as circumferential rotating wheel assemblies, and the circumferential rotating wheel assemblies are arranged and fixed side by side along the axial direction of the transmission shaft, so that the whole body can realize the axial rotation of the whole body and the circumferential movement of each ring. The minimum rated sizing size capable of conveying materials can be calculated by measuring the center distance of two adjacent circular rotating wheel assemblies and multiplying the distance by 2, and the specific formula is as follows:

L≥2*d

in the formula, L is the minimum rated size obtained in any direction of the material, and d is the central distance between two adjacent circumferential rotating wheel assemblies.

The invention has the advantages that rolling friction is generated when the materials advance along the axial direction, so that the friction force is greatly reduced, namely, the materials and the roller are protected, and the energy loss is also reduced.

The invention is further illustrated with reference to the following figures and examples.

FIG. 8 is a structural view of the propeller shaft (3)

In the figure, 1, a wheel set support welding part, 2, a small roller assembly, 3, a transmission shaft, 4, a clamping nut, 5, a shaft clamping ring, 6, a small roller, 7, an oilless bushing, 8, a mandrel and 9, a circumferential rotating wheel assembly are arranged.

The specific implementation mode is as follows: 2 oil-free bushes (7) are in interference fit with the small rollers (6), then the mandrel (8) sequentially penetrates through the inner hole of the wheel set support welding part (1) and the inner hole of the oil-free bushes (7) in a clearance fit mode, and the mandrel (8) is locked on the wheel set support welding part (1) by the shaft snap ring (5), so that the 1 small roller assembly (2) is assembled on the wheel set support welding part (1), and the remaining 3 small roller assemblies (2) are sequentially and completely assembled on the wheel set support welding part (1) to form 1 circumferential rotating wheel assembly (9), and the effect is shown in figure 2, and the small rollers (6) can rotate around the circumferential direction by the circumferential rotating wheel assembly (9). A plurality of circumferential rotating wheel assemblies (9) are sequentially assembled by the same method, then the circumferential rotating wheel assemblies (9) are sequentially inserted into the transmission shaft (3) and are mutually clamped at a rotating angle of 45 degrees, the effect is shown in figure 6, so that a circle can be formed by side projection, the effect is shown in figure 7, and the product with the rated size cannot be clamped when axially advancing. Finally, two tightening nuts (4) are used for locking two ends, and the circumferential rotating wheel assembly (9) is tightened, so that the roller capable of rotating bidirectionally can be obtained.

Claims
