Grinding spur gear

KSG1-36Grinding spur gearIntroduction:

KHK can produce a variety of spur gears based on various conditions such as different modules, tooth numbers, precision, shape, materials, as well as the presence or absence of heat treatment and grinding. The spur gear in the KHK product sample is commonly referred to as a spur gear.

What is a spur gear?

Spur gears, also known as spur gears, are cylindrical gears (mechanical elements) installed on two parallel shafts, with one shaft driving the other shaft to rotate. Spur gears have the advantages of simple production and easy achievement of high precision. Gears can be divided into three types based on the relative position of the gear shaft: parallel axis gears, cross axis gears, and cross axis gears. Straight gears, helical gears, and racks are all parallel axis gears. The meshing of spur gears is almost rolling contact, and their power transmission efficiency is 95-98%, which is very high. In a pair of meshing spur gears, the larger one is called the large gear and the smaller one is called the small gear.

Material of spur gear

KHK standard spur gears use JIS standard mechanical structure specific carbon steel S45C, SCM440 (medium carbon alloy steel), and SCM415 (low carbon alloy steel), gray iron FC200 in cast iron, SUS303 and SUS304 in stainless steel, C3604 (quick cut copper) for non-ferrous metals, MC901 and MC602ST for engineering plastics, and other materials. Of course, different countries and gear manufacturers use different specifications. For example, DIN in Germany, AISI, SAE, ASTM, AGMA in the United States, etc. For materials, we can perform heat treatments such as high-frequency quenching and carburizing quenching to increase hardness, as well as surface treatments to improve wear resistance and rust prevention.

Regarding the tooth profile and size of spur gears

The gear teeth used in industrial machinery are generally involute teeth. In addition, the size of teeth is generally represented by modulus, and the larger the modulus value, the larger the teeth. By increasing the gear module, a stronger allowable torque can be obtained.

Selection of KHK standard spur gears

Customers can pay attention to the following selection points when choosing spur gears from the KHK standard gear product line.

·The required speed communication ratio

·Load torque of gears

This element is affected by the modulus size and quenching

·The operating environment of gears

For example, gears are used in environments that are prone to rusting

·Required smoothness and noise level

Is this element affected by gear accuracy and grinding

·Gear shape

Do you need wheels, how long are the wheels, or do they come with axles

Xiaoyuan Gear Car Industrial Co., Ltd. provides a variety of spur gears according to customer usage purposes. Please refer to the spur gear product line for details.

Modulus: 1-3

Material: SCM440

Heat treatment: quenching and tempering · high-frequency quenching of tooth surface

Tooth surface machining: grinding

Gear accuracy: JIS N6

Gears that have undergone quenching and tempering, as well as tooth surface quenching and grinding, have excellent precision, strength, and wear resistance, and can be machined beyond the teeth.

Recommended for small gears for KRGF racks.
