YK3150 CNC Gear Hobbing Machine is suitable for batch, small batch and single piece production and processing of cylindrical gears and worm gears, as well as short spline shafts with 6 teeth or more with a length less than 300, and sprocket can be hobbed with sprocket hob. When machining cylindrical gears, reverse milling and forward milling and roll cutting can be used, and the full tooth width can be machined by axial feed (vertical feed). The NC hobbing machine hobbes the common worm gear by radial feed. When CNC hobbing machine processes spline shaft and sprocket, the adjustment and processing method of the machine tool are the same as when machining cylindrical spur gear. Widely used in high-precision machining of automobile power parts, transmission bearing gears and high-speed rail balance spline shafts; Its high-precision working characteristics are very suitable for machining high-precision gears, automobile half shafts, automobile transmission shafts and water pump motor shafts.

Copper worm wheel?
Copper worm gear has excellent conductivity, corrosion resistance, high hardness and wear resistance. Copper worm gear is usually made of tin bronze (such as ZCuSn10P1), which contains 10% tin and 1% phosphorus, and the rest is copper. It has high strength, elasticity and good wear resistance, and is suitable for atmospheric, fresh water and seawater environments. In addition, the copper worm gear has good antifriction and corrosion resistance, and can perform well under high-speed sliding and high-load conditions.
Copper worm gear is suitable for many fields, mainly including pharmaceutical, chemical and food industries. Copper worm wheels are commonly used in these industries for material crushing equipment, such as speed reducer, small crane, crystal ball grinder, lawn mower, elevator, gate, ship machine, automatic door, coal cake machine, woodworking machinery, harvester, printing and dyeing machine, shredder and so on.?
Chain wheel
Sprocket transmission is suitable for transmission with large center distance and has the characteristics of light weight and low cost. Because the chain has good elasticity and storage capacity of lubricating oil, the sprocket has good buffering capacity and vibration absorption capacity, and can work in harsh environments such as low speed, heavy load, high temperature and dusty. In addition, sprocket drive can ensure accurate transmission ratio and high transmission efficiency (generally up to 0.95~0.97), and the chain does not need great tension, and the load on the shaft and bearing is small.
Sprocket is a kind of wheel with embedded chain teeth, which is used to mesh with the block with accurate pitch on the link or cable. Sprockets are widely used in chemical industry, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.?
Spline shaft
Spline shaft is a kind of mechanical transmission, which transmits mechanical torque just like flat key, semi-circular key and inclined key. There are longitudinal keyways on the outer surface of the shaft, and the rotating parts sleeved on the shaft also have corresponding keyways, which can keep synchronous rotation with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gear shifting of gearbox. The spline shaft has the advantages of strong bearing capacity, stable transmission, compact structure, high transmission efficiency, convenient installation, high transmission precision, long service life and wide application range.
Spline shafts are widely used, mainly including aircraft, automobiles, tractors, machine tool manufacturing, agricultural machinery and general mechanical transmission devices.
Gear
As a common mechanical transmission element, gear has the characteristics of high transmission precision, high transmission efficiency, wide transmission ratio range, compact structure and so on. At the same time, it has strong wear resistance, strong bearing capacity, low noise, long life and high reliability. ??
As the core component of mechanical transmission, gear plays an irreplaceable role in many key industrial fields. First of all, in the field of machining, gear is an important guarantee for the accurate and stable realization of machine tool action, which can transform the high-speed rotation of motor into the low-speed and high-torque movement required by equipment. Secondly, the automobile field is also inseparable from gears. Whether it is a transmission, a rear axle or a steering gear, gears are needed to realize power transmission and adjustment. In addition, in the aviation field, gears are the key components of engines and various control surfaces, which require extremely high strength, temperature and weight. At the same time, CNC machining in the field of machine tools can not be separated from gears, which can achieve high-precision and high-speed machining through gears with different sizes and proportions. Finally, gear transmission system also plays a vital role in blast furnace and rolling mill in metallurgical field. In a word, gears play a key role in machining, automobile, aviation, machine tools, metallurgy and other fields, and are indispensable elements in industrial development.
