Spiral Bevel Gear
The spiral bevel gear has a curved pitch bevel teeth line. Similar to the meshing process of the straight bevel gear, its meshing is accompanied by the movement of the contact spots along the tooth height direction of the tooth surface. The contact area of the tooth surface starts from one end of the tooth and gradually moves to the other end. Due to the effects of overlapping tooth end faces (with several pairs of teeth entering into the mesh simultaneously), at least two teams of teeth are meshing simultaneously. Therefore, spiral bevel gears can transmit more load and work more smoothly than straight bevel gear and zero degrees spiral bevel gear of the same size (same module). Especially at high speeds, its noise and vibration are significantly less than those of the other two types of gears. The minimum number of teeth of spiral bevel gear can be reduced to six or even five, so the transmission ratio can be improved compared with the straight bevel gear.
Controlling the local contact area of the tooth surface is one of the main characteristics of the spiral bevel gear. The localization of contact significantly improves the stability of the work of the spiral bevel gear, reduces the noise, and improves the gear life. During gear cutting, the position and size of the best contact area of the tooth surface under the given working condition can be obtained through a slight change in the radius of curvature of the tooth surface of the mating gear.

The spiral bevel gears are divided into two types; one is the spiral bevel gear whose large wheel axis intersects the small wheel axis; one is the hypoid spiral bevel gear whose large wheel axis and small wheel axis have a certain offset distance. The spiral bevel gears are widely used in automotive, aviation, mining, and other mechanical transmission fields due to their advantages, such as large overlap coefficient, strong bearing capacity, high transmission ratio, stable transmission, and low noise.

FAQ
Q: Is there a rack and pinion on your website in stock?
A: Everything we do is made-to-order. All parts on our website are pre-designing and manufacturing when ordering, so you can request different sizes of end face widths, eyelets, wheels, etc.
Q: What is the payment term of your company?
A: Our payment terms are 30% down payment and 70% balance.
Q: Can you manufacture Gears that are not on this site?
A: Of course! We can provide custom gears with excellent delivery options as standard gears.
Q: Can you manufacture metric gears?
A: Of course! We have the tools to manufacture any metric size.
Q: What should I do if I cannot identify the gear?
A: Please send us your damaged gear!
A: We are a factory. We specialize in reverse engineering.
Q: Can you customize the product?
A: Send us the table, and we will let you know the minimum requirements for the part.
Q: How to get the lowest price?
A: Increase the quantity. The more parts you order, the lower the price you get.
Q: Can I use other materials besides steel to manufacture rack and pinion?
A: The price of racks is not fixed. Generally, we need to quote according to the customer’s required parameters such as material, tooth type, module, length, accuracy, style, spiral angle, and unique customization!
Q: Can I pay after you deliver the goods?
A: Sorry, we only accept payment before shipment.
