Product: Grinding Gears High Precision Spur Gears Cylindrical Gears Helical Gear

1. Cylindrical gears are a basic gear type that are widely used in various mechanical transmission systems. They are mainly used to transmit power and motion between two parallel shafts.

2. The characteristic of cylindrical gears is that the tooth surface of the gear is cylindrical, and the tooth shape is usually straight or helical (helical teeth).

Product introduction:

• Tooth shape: The tooth surface of spur gears is straight, while the tooth surface of helical gears is spiral. Helical gears provide smoother transmission and lower noise levels.
• Meshing mode: The meshing of cylindrical gears is line contact, which means that the meshing of the gears is carried out on a pair of teeth of the gears. Line contact can withstand greater loads than point contact of bevel gears.
• Transmission efficiency: The transmission efficiency of cylindrical gears is very high, and the theoretical maximum efficiency can reach more than 97%. Actual efficiency is affected by factors such as gear accuracy, lubrication conditions and operating speed.
• Manufacturing: Cylindrical gears can be manufactured through a variety of processing methods, including milling, grinding, shaving, etc. Machining accuracy and surface quality have a great impact on the performance of gears.
• Materials and heat treatment: Cylindrical gears are usually made of steel or cast iron and undergo heat treatments such as quenching and tempering according to the requirements of the application to improve their hardness and wear resistance.
• Design and calculations: Several factors need to be considered when designing cylindrical gears, including the diameter of the gear, the number of teeth, the module, the pressure angle, the tooth addendum height and the tooth root height. These parameters determine the size and load-bearing capacity of the gear.
• Application: Cylindrical gears are widely used in various machinery and equipment, such as automobiles, machine tools, wind and hydropower equipment, industrial machinery, etc.
