Helical Bevel Gears

The helical bevel gear refers to the tooth line on the crown wheel of the production shape, which is a straight bevel gear that does not go through the bevel top. The consecutive bevel gear pair has a relatively small number of teeth during transmission, prone to impact, unstable information, and loud noise. The bull gear and the pinion of a helical bevel gear pair have equal and opposite helix angles. The coincidence degree is greater than that of the spur bevel gear pair. Therefore, the noise and vibration are significantly reduced during high-speed operation, and the number of helical gear teeth of the helical bevel gear pair can be relatively reduced, thereby obtaining a larger transmission ratio and a compact structure;

In the unfolded surface drawing of the pitch bevel of the helical bevel gear, the pitch bevel gear line is tangent to a circle concentric with the pitch cone axis, so it is also called tangential bevel gear. Its advantages over straight gears are the same as the advantages of helical cylindrical gears over straight cylindrical gears: less impact load and more stable operation. However, due to the low productivity of this kind of gear, its performance is not as good as that of the spiral bevel gear, which can be mass-produced by a unique high-efficiency machine tool, so the latter gradually replaces it, and it is rarely used.

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-designed and will be manufactured 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 HZPT Machinery 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 HZPT Machinery 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.
