When hobbing with a rack-type pillar, when the reference line of the rack cutter is tangent to the pitch circle of the rack, the cut gear is a standard gear; when the reference line of the rack cutter is not in line with the pitch circle of the wheel blank When cutting, the gear cut out is a displacement gear.
The distance between the tool reference line and the wheel blank index circle is called the displacement, expressed in xm, and X is called the displacement coefficient.When the tool leaves the center of the blank, X takes a positive value (called positive deflection), otherwise X takes a negative value (called negative deflection).For helical gears, the relationship between the end surface displacement coefficient and the normal displacement coefficient is X1=XN.
After the gear is modified, its tooth shape is involute with the standard gear, but the application field is different.Taking advantage of this feature, a good involute section can be obtained by selecting the variation coefficient X, thereby improving the transmission performance of the gear.The application of the modified gear can avoid undercutting, improve the contact strength of the tooth surface and the bending strength of the tooth root.In addition, modified gears can also be used to match the center distance.

How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
