According to the requirements of the sprocket gear: if the impact force is small in the case of small can be its surface carburizing, nitriding and other technologies! So that the surface hardness is higher, and the matrix hardness is lower, wear resistance is good, and not easy to fracture. If the impact load is large, it is due to the tempering treatment, that is, high temperature tempering. 45# steel quenching temperature in about 580 degrees, holding time has a formula, according to your equipment, the size of the workpiece, shape, and then quenching, and then with about 500&#8...

Gear products, because of their special characteristics, must be designed to take into account the effects of their blanks, machining, heat treatment and testing. Manufacturing-testing integration can optimize materials and processes, quantitative evaluation, help decision-making, and improve product power density. Especially for arc gear bevel gears, because of its tooling for non-standard design, the same series as far as possible to achieve generalization and serialization. In addition, gear design, but also focus on its heat treatment deformation of the impact, such as not to make the top of the tooth is too sharp, and the root of the tooth...

Current industrial applications of gear finishing methods are mainly shaving, grinding, extrusion, research and honing. Shaving is in the shaving machine with shaving cutter shaving, is a method of gear finishing, shaving cutter is equivalent to the tooth surface opened a lot of edge of the helical gear. It drives the relative rotation of the gear being processed, as staggered shaft gear meshing, relying on the relative sliding on the tooth surface, shaving cutter cut off a very thin layer of metal on the tooth surface, to complete the gear finishing, shaving machine skateboard adjustments to ensure that the gears...

Sprocket gear machining is an extremely complex process, and only by utilizing the correct technology can efficient production be made possible, and each part of the production process must also be of extremely precise dimensions. Gear processing cycle includes general turning → hobbing → gear insertion → shaving → hard turning → grinding → honing → drilling → bore grinding → welding → measurement, for this process to configure the appropriate clamping system is particularly important, next we will introduce the various...

(1) Rough machining This sequence is the process of transforming from blank to semi-finished product. In order to reduce the cost and improve the machining efficiency, it is arranged on the Czech Skoda W200H digital floor boring machine, using φ 200mm cutter, φ 315mm three-face milling cutter and φ 25mm cutter for machining. First of all, φ 200mm cutter is used to process 6 faces of the rack, leaving 10mm machining allowance on one face, and then φ 315mm three-face edged milling cutter is used on the universal angle head to cut a straight groove along the tooth contour, and then the workpiece is stood on its side, and φ ...

The reason for root cut: when the intersection of the tool tooth top line and the meshing line exceeds the meshing limit point N1, the tool continues to move from position Ⅱ, it will be the root has been cut out of the involute tooth profile and then cut off part of it. Consequences of root cut: produce serious root cut gear, on the one hand, weaken the bending strength of the gear teeth; on the other hand, will make the gear transmission of the degree of cooperation has been reduced, which is very unfavorable to the transmission. The reason for root cut: when the intersection of the tool tooth apex line and the meshing line exceeds the meshing limit...

What is a Magnetic Gear? Magnetic Gear (Magnet Gear), also known as Magnetic Wheel, is a non-contact power transmission device that utilizes the principle of the interaction between the suction and repulsion forces of magnets. Product Features Dust-free environment: Using magnetic force, torque transmission can be utilized in a non-contact state to transmit products within a vacuum that requires a dust-free environment. Low gas emission: Large machines to vacuum machine, in order to reduce gas emission, according to the special surface treatment, can be used in the environment of 10-5PA. Ultra low...

Spur Gears The most common gears are straight toothed cylindrical gears used for large gear reduction. The teeth on a spur gear are straight and mounted parallel on different shafts. Spur gears are used in washing machines, screwdrivers, wind-up alarm clocks, and other devices. Because gears mesh and collide, each impact makes a loud noise and causes vibration, which is why straight cylindrical gears are not used in machinery such as automobiles. A normal gear ratio ranges from 1:1 to 6:1. spiral...

All bevel gears have much in common in their design and manufacture, but those destined for use in pulverizers must have certain critical characteristics that are not standard since the automotive industry. As is often observed in the large bevel gear industry today, these critical characteristics are not widely understood in the engineering community, let alone in the much smaller number of gears for which manufacturers are expected to be fully aware of the technical requirements for these applications. For pulverizer applications, the gear's working shaft relies on plain bronze bushings...

TSH technology is an advanced induction hardening process specifically designed to reduce overall costs and replace chemical heat treatment processes. Conventional heat treatment of sprocket gears consists of prolonged gas carburizing in batch or continuous furnaces followed by oil quenching. Typically, the gears are tempered in a low-temperature furnace for one hour. After carburizing, the gear surface area typically has a carbon content in the range of 0.7-1.0% C and a hardness in the range of 58-63 HRC. post-treatment includes grinding and shot peening to improve fatigue strength...
