According to the requirements of the sprocket gear: if the impact is small case small can be surface carburizing, nitriding and other technologies! This way the surface hardness is higher, while the base hardness is lower, the wear resistance is good, and it is not easy to fracture. If the impact load is large, it should be tempered, that is, high-temperature tempering. 45#...
The materials used to make sprockets and gears are generally grey cast iron, low carbon steel, medium carbon steel, low carbon alloy steel, medium carbon alloy steel, etc. according to the application. (HT20-40, HT25-47, HT30-54, 45# steel, 40Cr, 40MnB, 15, 20, ...
Due to their specificity, gear products must be designed taking into account the influence of all aspects 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 bevel gears with curved teeth, since their tools are of non-standard design, the same...
At present, the main methods of gear finishing for industrial applications are gear shaving, gear grinding, gear squeezing, gear grinding and gear honing. Gear shaving is a method of gear finishing by shaving the teeth with a shaving knife on a shaving machine, which is equivalent to a helical gear with many edges on the teeth. It drives the relative rotation of the processed gears, just like the interlocking shaft gear mesh...
Sprocket gear machining is an extremely complex process that can only be made possible by using the right technology, and each part of the production process must also be dimensioned to an extremely precise level. The gear machining cycle includes general turning → hobbing → shaping → shaving → hard turning...
(1) Rough machining This procedure is the process of transforming from blank to semi-finished product. In order to reduce the cost and improve the machining efficiency, the machining is arranged on a Czech Skoda W200H digital display floor boring machine with φ 200mm cutter, φ 315mm triple-edge milling cutter and φ 25mm cutter. Firstly, we adopt...
The cause of root cut: When the intersection of the tool tooth top line and the mesh line exceeds the mesh limit point N1, and the tool continues to move from position II, the involute tooth profile that has been cut out of the root is cut off again. Consequences of root cutting: A gear with severe root cutting, on the one hand, weakens the bending strength of the gear teeth; on the other hand, it will...
What is Magnet Gear? Magnet Gear (Magnet Gear), also known as magnetic wheel, is a non-contact power transmission device that uses the principle of interaction between the suction and repulsion of a magnet. Product features dust-free environment: Using magnetic force, it can use torque transmission in a non-contact state, and in the need for a dust-free environment...
Spur Gears The most common gears are straight cylindrical gears, which are used for large gear reductions. The teeth on spur gears are straight and mounted parallel to each other on separate shafts. Spur gears are used in washing machines, screwdrivers, wind-up alarm clocks, and other devices. Because gears mesh and collide, each impact produces a loud noise...
All bevel gears have much in common in their design and manufacture, but those destined for use in shredders must have certain key characteristics that are not part of the industry standard since automotive. This phenomenon is often observed in the large bevel gear industry today, and these critical characteristics are not widely understood in the engineering community, let alone...
TSH technology is an advanced induction hardening process specifically designed to reduce overall costs and replace chemical heat treatment processes. Traditional heat treatment of sprocket gears consists of a long gas carburization in an intermittent or continuous furnace followed by an oil quench. Typically, the gears are tempered in a low-temperature furnace for one hour. After carburizing,...
1, according to the load, and the state of motion (speed, vertical or horizontal motion) to calculate the drive power 2, the initial estimate of gear modulus (if necessary, the subsequent gear strength check, if in the strength check, found that the modulus selected too small, you must redefine the gear modulus, on the selection of gear modulus...
Gear pump is a common fluid transfer and transmission components, due to its simple structure, high efficiency, not easily contaminated by oil, and is widely used in aviation, aerospace, shipping and automotive fields. With the progress and development of science and technology, the performance requirements of gear pumps are getting higher and higher, mainly in order to achieve high gear pump...
1. Milling, this is the use of disc-shaped modulus milling cutter or finger-shaped milling cutter teeth is part of the molding processing method, milling cutter tooth cross-section shape and gear tooth shape is the two corresponding. This method is not only low efficiency and processing accuracy is relatively low, is suitable for single-piece small batch production. 2. Forming and grinding is also...
Hobbing The hobbing gear belongs to the spreading method, which can be regarded as a gear without meshing gap and rack drive. When the hobbing gear rotates for one week, it is equivalent to the rack moving a knife tooth in the normal direction, the continuous transmission of the hob is like an infinitely long rack moving continuously. When the hob and hob blanks in strict accordance with the gear to rack ratio...
There are 10mm-1600mm diameter, 1-36 modulus, and GB5-GB8 accuracy level of spiral bevel gears. According to the different design method, processing method and processing equipment, spiral bevel gears can be divided into German Klingelnberg spiral bevel gears, American Gleason spiral bevel gears...
In rack and pinion steering, the steering gear, which is the active part of the transmission, is mounted in the housing and engages with the horizontally arranged steering rack. The spring presses the rack against the steering gear by means of a pressure block to ensure a backlash-free engagement. The preload of the spring can be adjusted by the adjusting screw. >> During operation, the steering gear...
Sprocket gear tooth surface processing can be divided into forming method processing and spreading method processing 1, tooth surface forming method processing: The forming method processing of tooth surface refers to the use of forming tools to process the workpiece. Gears manufactured by this method are less accurate and can only be used in low-speed environments. Forming method of common processing methods include milling...
