plastic bevel gears Alibaba
Product Description
Gears are widely used for power transmission. They are widely used in automobile, gearbox, oil engine, machine tool, industrial machinery, agricultural machinery, gear motor and other fields to meet the requirements of solid structure, reliable performance, high efficiency, economy, long life.
Gears can be produced by a variety of casting processes. Casting economy, large volume, large module, but the gear surface rough, size is not accurate. These gears are suitable for machines with low operating speed, noise and high accuracy
What is a helical gear
Spur gears with helical teeth (helical teeth) are called helical gears. Helical gears can withstand greater loads than spur gears and work more quietly. They are also widely used in different industries, such as automobiles and industrial machinery.
Helical gears are the more common type of gear and can be used in many applications. The teeth of a helical gear are cut at an Angle to the surface of the gear so that the engagement of the teeth begins at one end and is gradually transferred to the remaining teeth as the gear rotates. The helical gear design reduces noise and makes the whole system smoother. When the teeth of a gear contact each other at angles not perpendicular to the axis, the helical pattern of the gear produces thrust loads. Bearings are usually incorporated into a mechanism with helical gears to support this thrust load.
The teeth of helical gears are set at an Angle (relative to the axis of the gear) and are helical. This allows the teeth to engage gradually, starting with point contact and developing line contact as engagement progresses. One of the most obvious advantages of helical gears over spur gears is that they are less noisy, especially at medium and high speeds. Similarly, with helical gears, multiple teeth are always engaged, which means there is less load on each individual tooth. This smoothes the transfer of force from one tooth to another, reducing vibration, impact loads and wear.
Helical gear processing technology
Helical gears can be machined with a variety of materials and a variety of precision gear processing methods. The methods used include shaping, milling, hobbing and casting. Materials used range from steel, cast iron to aluminum bronze. The materials used in gear design also play an important role in its performance and should be evaluated against practical application. Here, temperature, speed and load can all help determine requirements. The hobbing process of helical gear will be introduced below.
In the hobbing process, the helical gear blank is mounted on the shaft and the steel is compressed on the rolled die. During the several rotations that produce the helical gear teeth, the drum gradually feeds inward. The forming roller is very accurate. The helical gear teeth of hobbing usually include cold and cold forms. In the absence of hobbing, non-rolling helical gears are usually cold-rolled, giving them a smooth mirror finish. In the cold roll forming process, the higher pressure required by the process does not require further finishing than without rolling multiple gears. It becomes more resistant to tension and fatigue. Both spur and helical gears can be manufactured by this process.
FAQ
