Influence of bolt assembly location on bolt connection performance: Shanghai giant Bearing Co., Ltd.

Bolt connection is widely used in modern machinery industry, especially in pressure vessel industry. Its advantages are reliable connection, easy disassembly and maintenance. The initial pretightening force on the bolt can not only guarantee the sealing performance of the connection [1], but also make the connecting parts do not move relative to [2] under the action of external loads. The common failure modes of bolts include fatigue, shearing and loosening of bolts. The failure of bolts will not only increase the maintenance cost and unnecessary downtime of industrial machines, but also cause serious industrial accidents, [3]. [4]. The good bolt connection performance depends not only on the initial preload force [5G7], the contact surface friction coefficient [8G9] and material [10], but also on the bolt diameter [[11]] and the assembly position between bolt and bolt hole.

Installation method of printing machine bearing Shanghai giant Bearing Co., Ltd.

How to install the bearing of printing machine? The pressure should be directly applied to the ends of tightly matched rings, and the pressure should not be passed through the roller body. Usually, the following methods are adopted: when the outer ring of the bearing is tightly matched with the hole of the bearing seat, the bearing can be pressed into the first hole of the bearing seat when the inner ring and the shaft are loosened. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing rings and shaft are closely matched with the seat holes, the installation of the inner ring and outer ring must be pressed into the shaft and the hole at the same time. The structure of the assembly sleeve should be able to simultaneously press the end face of the bearing inner ring and outer ring. 1. By heating the bearing or bearing box, the thermal expansion is used to convert the tight fit to the loose fitting installation method. This is a common and labor-saving installation method. This method is applicable to bearings with larger interference. Before hot assembly, the bearing or detachable bearing ring is put into the tank and heated evenly at 80-100 degrees, and then from the oil.

Analysis of common faults of printing machine bearings Shanghai giant Bearing Co., Ltd.

The modern multicolor offset printing machine has an intermediate roll digital printer. The intermediate roll is the communication bridge of ink and wash road. In addition to achieving fast water and ink balance, it also removes floating ink on the water roll. During the printing machine operation, the plate shaped water roller contacts directly with the fish. Inevitably, there will be some floating ink CTP sticking from its surface. These floating ink may deposit on the surface of the water roller, thus affecting the hydrophilicity of the water roller, or may return to the sink with the fountain solution, thus affecting the wettability of each color group. Using this intermediate roll, the floating ink can be transferred to the ink roller of the adjacent printing plate in time, so it is integrated. It has little effect on printing products, and it can also effectively improve production efficiency. Imported bearings of pre press equipment often fail during high speed operation. 1. There is no need to make a fuss, but this is the right way to judge and deal with faults in time.

Calculation method of joint bearing Shanghai giant Bearing Co., Ltd.

Because the spherical sliding contact area of the joint bearing is large and the inclination angle is large, and because most of the joint bearings adopt special machining methods, the rolling bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Spherical bearings are usually used for low speed swing motion, that is, angular motion. Because the sliding surface is spherical, it can also perform oblique motion in a certain angle, that is, self alignment motion. You can still work normally. Calculation method: the spherical sliding bearing has two mating spheres. This connection is called coordination. The calculation method of the mechanical properties of spherical plain bearings plays an important role in the structural design and wear analysis of spherical sliding bearings. The calculation of the contact pressure on the surface is a very complicated problem. The existing Hertz model can not be used to calculate the contact pressure distribution of spherical coordinates, because it is limited to elastic half space body. At present, there is a unified spherical contact model, namely Fang mode.

How to maintain the Shanghai bearing giant Bearing Co., Ltd.

Metal linear bearing is a linear motion system which is produced at low cost. It is used for infinite stroke and cylindrical shaft. The following is a brief introduction to the maintenance method of linear bearings. Maintenance of metal linear bearings: lubrication and friction: injecting oil into the linear bearings. If grease is lubricated, remove the anticorrosive oil with kerosene or organic solvent, then add grease after drying. It is recommended to use lithium sticky grease labeled as N0.2. If oil is lubricated, it is not necessary to remove the anticorrosion oil. According to the temperature change, the lubricating oil with ISO viscosity class VG15-100 can be selected. The shaft lubrication can be supplied from the oil supply pipe or from the oil hole on the outer bearing seat. Because the sealing ring will scrape the lubricating oil, the oil lubrication is not suitable for the sealed bearing without holes. Maintenance of plastic linear bearings: because the sliding film inside the plastic linear bearing is made of self-lubricating plastic, there is no need for additional oil supply and maintenance during its use.
