Shaft Forging

shaft forgings I. product introduction Shaft forgings are cylindrical objects inserted between bearings or wheels or gears, but some are square. Shaft forgings are mechanical parts that support rotating parts and turn with them to transfer motion, torque, or bending moment. It is usually a round metal rod with different diameters. The rotating parts of the machine are mounted on the shaft forgings. Ii. Product parameters 1) dimensional accuracy the dimensional accuracy of shaft parts mainly refers to the dimensional accuracy of shaft diameter and shaft length. According to the requirements of use, the diameter accuracy of the main journal is usually it6-it9, and the precision journal can be up to IT5. The dimension of shaft length is usually specified as nominal dimension, and the length of each step of step shaft can be given a tolerance according to the requirements of use. 2) geometric precision shaft parts are generally supported on the bearing by two journal, which are called support journal and also the assembly datum of the shaft. In addition to the dimensional accuracy, the geometric accuracy (roundness, cylindricity) of the support journal is generally required. For the general precision of the shaft neck, the geometric shape error should be limited to the diameter tolerance range, when the requirements are high, the allowable tolerance value should be specified separately on the part drawing. 3) accuracy of mutual position matching journal of shaft parts (the journal for assembling transmission parts) relative to the coaxiality of the support journal is a universal requirement for accuracy of mutual position. In general, the radial circular runout of the shaft neck with the matching precision is 0.01-0.03mm, and the high-precision shaft is 0.001-0.005mm. In addition, the mutual position accuracy has the coaxiality of the inner and outer cylinder, the perpendicularity of the axial positioning end face and the axis line. 2, surface roughness according to the precision of the machine, the high and low running speed, shaft parts surface roughness requirements are not the same. In general, the surface roughness Ra of the support journal is 0.63-0.16 microns. The surface roughness Ra of the matched shaft neck is 2.5-0.63 mu Iii. Product advantages Shaft, sleeve and disk parts are typical parts with cylindrical surface. The common machining methods for the outer surface include turning, grinding and various finishing machining methods. Turning is the most economical and effective machining method for outer circular surface, but in terms of its economic accuracy, it is generally suitable for rough machining and semi-finishing machining of outer circular surface. Grinding is the main finishing method of the outer surface, especially suitable for all kinds of parts with high hardness and quenching. Finishing machining is an ultra-precision machining method after finishing (such as rolling, polishing, grinding, etc.), which is suitable for some parts with high precision and surface quality requirements. Due to various processing methods can achieve economic processing accuracy, surface roughness, productivity and production cost are not the same, so must according to the specific situation, choose a reasonable processing method, so as to process qualified parts to meet the requirements of the parts drawings.

Square Shaft Forging

Square shaft forgings Introduce the product Square shaft forgings are cylindrical objects worn between bearings or wheels or gears, but a few are square.The material of the shaft is mainly carbon steel or alloy steel, but also ductile iron or alloy iron.The working capacity of the square axis generally depends on the strength and stiffness. Product advantage The common machining methods of square shaft forging shaft surface include turning, grinding and various finishing methods.Turning machining is the most economical and effective machining method for cylindrical surface, but in terms of its economic precision, it is generally suitable for rough machining and semi-finishing machining methods for cylindrical surface.Grinding is the main finishing method of the surface of the outer circle. It is especially suitable for the finishing of various parts with high hardness and quenching.Finishing machining is a super precision machining method (such as rolling, polishing, grinding, etc.) after finishing, which is suitable for some parts with high precision and surface quality requirements.As a result of various processing methods can achieve the economic processing accuracy, surface roughness, productivity and production costs are not the same, so must be based on the specific situation, choose a reasonable processing method, so as to meet the requirements of the parts on the drawings of qualified parts.

Gear Shaft Forgings

Gear shaft forgings I. product introduction A gear shaft forging is a mechanical part that supports a rotating part and turns with it to transmit motion, torque, or bending moment. It is usually a round metal rod with different diameters. The rotating parts of the machine are mounted on the shaft. Gear shaft forging is the shaft and gear synthesis of a whole, but, in the design, or to shorten the length of the shaft, too long is not conducive to hobbing machine processing, the second is the support of the shaft is too long to lead to the shaft to be thick and increase the mechanical strength (such as rigidity, deflection, bending, etc.). Ii. Product parameters Iii. Product advantages In the process of gear shaft forging, the selection of positioning reference should be considered as follows: at the beginning, the outer circle should be used as the center hole of the end face of the rough reference to prepare positioning reference for the rough car; The rough turning outer circle is the positioning reference for the subsequent processing: after that, in order to prepare the positioning reference for the semi-finishing and finishing outer circle, the center hole before and after processing is used as the positioning reference. Gear shaft forgings also use the center hole as the positioning reference, which is a very good embodiment of the principle of unity of reference, also fully embodies the principle of coincidence of reference. In the whole process of shaft machining, enough heat treatment procedures should be arranged to ensure the mechanical properties of gear shaft and machining accuracy requirements, and improve the workpiece processing properties. In general, normalizing treatment is arranged first after shaft blank forging to eliminate the internal stress of forging, refine the grain and improve the cut

Step Shaft Forging

step shaft forging Introduce the product Step shaft forging is a kind of shaft forging.The stepped bushing is particularly suitable for precision bearing configurations, offering lower runout and higher accuracy than threaded lock nuts. Step shaft forging sleeve is usually used for ultra-high speed spindles for which conventional locking devices cannot provide sufficient precision. Step shaft forgings - shaft forgings with shoulder made up of different outside diameters. Product advantage Ladder shaft forging is a kind of wide application of forgings, such as axial plus has good processability, m any porosity in the practical application, and no other flaws, thus not only has good appearance, with fine, here is how to introduce you to conform to the requirements of axial forgings to be popular. 1. High intensity Ladder shaft forgings during processing, its claim to have high accuracy, can not have any flaws, manufactured by forging processing method of this kind of shaft parts, its strength and weight have a higher ratio, its strength is very high, can well ensure shaft parts in the long-term use can resist friction for a long time. Ii. Exquisite appearance Popular and respected axial forgings, must have enough quality and appearance, so there is a need for shaft parts has beautiful shape, the characteristics of its in processing link, also need to surface treatment, on the one hand, in order to improve its performance, on the one hand is to improve the appearance of fine degrees. 3. Good physical properties Step shaft forging is made by applying a certain amount of pressure, and then through plastic deformation, it has built a very delicate particle structure in the process of forging, so the physical properties of shaft parts have been greatly improved, so that it can have excellent physical properties in practical applications.
