Stainless steel roller features: high wear resistance, low friction coefficient, easy to wear belts; self lubrication, no oil good, not easy to use in harsh conditions of death; stainless steel roller with antistatic, flame resistance, aging resistance, chemical resistance (acid, alkali and organic solvent). Corrosion.
Stainless steel roller is also called the 304 roller, white steel roller and antimagnetic roller, the roller iron in addition to stainless steel is mainly used in belt conveyor or underground power plant, prevent the stainless steel roller was separator suction. Because the roller is in the head of the adhesive tape machine, the impact is relatively large, so the roller tube, roller shaft, bearing seat and bearing and axle are stainless steel. But all use stainless steel cost is very high, so in recent years all changed to the rest of the skin of stainless steel tube, ordinary material, so there is no effect of the use of the first half, the price lower than before, can do an example, before the full stainless steel 200 yuan, stainless steel tube skin only needs 100 yuan, which greatly saves a lot of cost for customers.
Installation technology of roller bearing seat
On the one hand, in the actual production process, the use of the new roller bearing seat assembly process, both ends of the roller is not processed, no welding. The first step of the roller shaft into the tube and positioning, the second bearing seat assembly has been beneficial to the processing requirements, directly into the tube. In the pressing process, bearing the equivalent of a mould can be roller round the school tube, greatly reducing the both ends of the roller radial jump error, and reduce rotation resistance, improve the production efficiency of conveyor.
On the other hand, we can make use of the new technology. The metal heat riveting technology is a new technology of bearing and roller connecting, by local heating of non-metallic materials, plastic contact riveting die after cold forming again, so as to realize the fastening function, the production process can be implemented efficiently without changing the physical and chemical properties of the original material, no additional waste. The utility model has the advantages that the assembly of the non-metal bearing seat and the metal roller is integrally assembled into a whole, and the production process has the advantages of strong processing capacity, high efficiency, good appearance and firm connection. It can effectively prolong the service life of roller and meet the requirements of mass production.
This process is used to produce the roller bearing seat. It can effectively overcome the shortcomings of the traditional production of the roller, such as water resistance, corrosion resistance, impact resistance and so on. The weight of the roller is greatly reduced, and the weight of the supporting roller is reduced by half than that of the traditional process. Easy maintenance, easy maintenance and reuse of parts. The accuracy of the process to increase, this new type of non metal bracket between the roller bearing seat and roller to fit, by pressing and riveting bearing center hole positioning, effectively ensure the roller and roller bearing seat concentricity, reduce runout, reduce the overall weight of the roller, prolong the service life of the roller. The technology can be developed in the riveting equipment, using one of a roller bearing riveting, thus greatly improve the production efficiency, the use of new materials and new technology will make the roller product upgrading fundamentally. |
