Description

New Belt Roller Device

technical field

The utility model relates to a novel belt roller device, which belongs to the field of mechanical processing and manufacturing.

Background technique

At present, belt rollers are widely used in various industries and daily life. Many industries, especially the manufacturing and processing industry, tobacco industry, mining machinery and other online material transportation are widely used. The belt roller is installed on the frame of the equipment through the bearing seat. Or on the wall, and the belt roller is an integral processing part. Usually the faulty part of the belt roller is the bearing seat and the shaft assembled with the bearing seat. If one end of the shaft head is worn, it must be replaced as a whole, resulting in high maintenance costs, and it is also difficult to disassemble, that is, the belt roller If it is damaged, the bearing housings at both ends and the belt pulley must be disassembled together.

The fundamental way to solve the above problems is to design the belt rollers into several components, so that the parts that are prone to damage can be quickly disassembled, easy to maintain and simple to process. For this reason, many enterprises have carried out some explorations, such as a kind of belt roller device disclosed in the CN201942281U utility model, which divides the belt roller into three parts: the left end shaft, the roller assembly and the right end shaft, and the connection part adopts a square structure , the axial positioning is on the shoulders of the left end shaft and the right end shaft. The square shoulder and square hole have high technical requirements, difficult processing, and high manufacturing cost. When disassembling and maintaining, they must be removed together with the bearing seat, and the installation of the connecting part is not easy When in place, there will be axial serial movement of the roller assembly. But all do not solve the problems of fast disassembly, simple processing and convenient maintenance.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of belt roller device that can be disassembled quickly, has a compact structure, is convenient to maintain and is simple to process in order to overcome the above-mentioned shortcomings in the prior art.

The technical scheme that the utility model solves its technical problem adopts is:

A new type of belt roller device, which includes a left trunnion 1, a roller 2, a right trunnion 3, an elastic gasket 4, a fastening bolt 5, flanges 6 located on the left and right sides of the roller and located on the The roller end plates 7 on the left and right sides of the roller, the left trunnion 1 and the flange 6 on the left side of the roller form a left trunnion assembly, and the roller 2 and the flanges on the left and right sides of the roller The roller end plate 7 forms a roller assembly, the right trunnion 3 and the flange 6 on the right side of the roller form a right trunnion assembly, and the left trunnion assembly is connected to the left side of the roller assembly, so The right trunnion assembly is connected to the right side of the roller assembly.

Preferably, the connection between the left trunnion 1 , the roller 2 , the right trunnion 3 , and the flange 6 and the roller end plate 7 is a structure of concave-convex surface positioning and bolt fastening connection.

Preferably, the flange 6 is provided with 6 through holes for bolt connection and 2 threaded through holes for disassembly and maintenance.

The beneficial effect of the utility model is that the belt roller can be processed in separate parts, and can also be assembled in separate consignment on site, which reduces the overall processing difficulty of the belt roller and reduces the manufacturing cost. At the same time, during maintenance, since the left trunnion assembly and the right trunnion assembly can be disassembled separately, the labor intensity of the maintenance personnel is reduced, and the maintenance cost is also reduced. Because of its compact structure, convenient maintenance and simple processing, the utility model is not only suitable for the tobacco industry, but also suitable for other industries.
