spur gear

1.A herringbone gear, a special type of double helical gear, is a special type of gear that is a side-by-side (not face-to-face) combination of two helical gears in opposite directions. Viewed from the top, each of the gear's spiral grooves looks like the letter V, and many of the spiral grooves together form a herringbone pattern. Unlike helical gears, herringbone gears do not create additional axial loads. Like helical gears, they have the advantage of delivering power smoothly because more than two teeth are in mesh at any one time. Their advantage over helical gears is that half of the side thrust is balanced by the other half of the side thrust. This means that herringbone gears can be used in torque gearboxes without the need for extensive thrust bearings. The herringbone gear was therefore an important step in the introduction of steam turbines for ship propulsion. Precision herringbone gears are more difficult to manufacture and therefore more expensive than equivalent spur or helical gears, so they are often used in heavy machinery. 2.Our company mainly produces non-standard mechanical products such as rotary bearings, gear rings, and shafts, which can be customized according to customer requirements. Gear shafts can produce structures such as straight teeth, helical teeth, and herringbone teeth. Rotary bearings have external teeth, internal teeth, and no teeth. We have cooperated with many new and old customers both domestically and internationally,The factory is fully equipped with professional workers and technical teams, and a complete sales team provides one-on-one service in terms of service. and we believe we welcome inquiries.

1.A combination of left and right helical gears with the same helix angle is called a double helical gear, which transmits rotational motion between parallel axes. 2.Double helical gears and herringbone gears are the same type of gear, but those with grooves between the left and right helical teeth are called double helical gears, those without grooves

Select high quality 35CrMo, 42CrMo, C45 steel material, and alloy steel according to customer's requirements. Full production line for processing and can provide one to one customization service to customers. Support teeth quenching, teeth grinding, surface treatment like Carburizing，Nitriding etc. Good at high precision ring gears processing with professional inspection teams.

Ring gear, Gear wheel or Girth gear is a part used in mechanical transmission. Material is usually forged or casting alloy steel with surface carburizing or hardening treatment. The gear has the high bearing capacity and durability in practical application, which is widely used in high speed and heavy load machinery because of its stable transmission, low impact, vibration and noise. The ring gear from our company is precisely designed using high quality raw material, and finish of the gear is with high precision too.Our quality experts check the product at each and every stage of manufacturing process according to the international industrial standards. Our company can produce different type gear ring and wheel such as spur gear, helical gear, worm gear, large ring gear according to the customer's drawing and requirements. Our product is highly appreciated amongst customers for its dimensional accuracy, excellent strength and high performance. Teeth quenching, teeth grinding and surface treatment like oxide, nitriding, sandblasting are also available.

Ring gear is made of 42CrMo quenched and tempered material. Module is 4.5 and teeth No. is 69. To improve the hardness of the gear, we make nitriding treatment for it. The holding temperature of the nitriding process is generally 460-600 ℃, which is a chemical heat treatment process in which active nitrogen atoms are infiltrated into the surface of the gear. After nitriding, the distortion of the gear is small, and it has higher hardness than carburizing, which can increase wear resistance, fatigue strength, anti-seizure performance, corrosion resistance and high temperature softening resistance, etc. It is widely used in automobiles and machine tools for higher requirements of wear resistance capacity.

Pinion gear is a part used in mechanical transmission. Material is usually forged alloy steel with surface carburizing or hardening treatment. The gear has the high bearing capacity and durability in practical application, which is widely used in high speed and heavy load machinery because of its stable transmission, low impact, vibration and noise. The ring gear from our company is precisely designed using high quality raw material, and finish of the gear is with high precision too.Our quality experts check the product at each and every stage of manufacturing process according to the international industrial standards. Our company can produce different type pinion gears such as spur gear, helical gear, worm gear according to the customer's drawing and requirements. Our product is highly appreciated amongst customers for its dimensional accuracy, excellent strength and high performance. Teeth quenching, teeth grinding and surface treatment like oxide, nitriding, sandblasting are also available.
