It has been committed to providing TPV with mould-related accessories, and also provides customers with high-quality hollow shafts and hollow shafts. Stepped shaft and other products. A hollow shaft means that a through hole is made in the center of the shaft body, and an inner keyway is opened in the through hole. The outer surface of the shaft body is machined with a stepped cylinder and an outer keyway. The outer surface of the shaft body is machined with a stepped cylinder and an outer keyway is opened. The central through hole of the shaft is sleeved with the main shaft of the press chamber. The input power is directly driven by the transmission gear mounted on the cylinder on the outer surface of the shaft. Passed to the press bore spindle. The hollow shaft occupies a relatively large volume, but it can reduce the weight. According to the analysis of material mechanics, when the rotating shaft transmits torque, from the radial cross section, the more the outer place transmits the effective torque, the greater the effect. When the rotating shaft needs to transmit a large torque, a thicker shaft diameter is required. However, since the torque transmission at the shaft center is relatively small, the hollow shaft is generally used to reduce the weight of the shaft. The basic processing steps of hollow shaft are as follows A.Rigid coupling: sleeve type, sandwich type, flange type. B.Classification of shafts: 1.According to different loads: rotating shaft, mandrel, drive shaft. Mandrel: rotating mandrel, fixed mandrel, bearing only bending moment, not bearing torque. Drive shaft: bearing only torque, not bending moment. 2.According to the shape of the axis: crankshaft and straight shaft. 3.According to the shape: optical axis, stepped axis. C.Determinants of shaft structure: 1.The position of the shaft and the machine 2.Put several parts on the shaft 3.The direction and size of the axis change 4.Processing technology. D.Expected calculated life: According to the number of revolutions or working hours before pitting damage occurs in 10% of the bearings in a group of bearings, and 90% of the bearings do not have pitting damage, the life of the bearing is called the basic rating life. Design the machine The life of the bearing required at the time is the expected calculated life. FAQ 1.How do I place an order? You can contact any of our sales staff to order.
