Frequently asked questions
Shiuh Cheng introduced the most advanced gear profile grinding machine from Germany to improve the quality of gears. We offer customized gears, and a small amount of customization is possible. If you have any questions regarding our products, you can also refer to the FAQ's sections.
Precision gears, also known as silent gears, and the gear surface grinding-grade must be above JIS2 (or DIN6). After the tooth surface there has been heat treatment hardening such as carburizing or high...
Read moreThe common precision gear materials and heat treatment are as follows. If you have other materials and heat treatment requirements, please contact Shiuh Cheng.
Read moreGear accuracy is judged by the error level. The accuracy consists of three components, namely the tooth profile (ie the pressure angle), the Lead (ie the helix angle) and the pitch. Attached is an example...
Read moreBoth represent the size of the gear tooth, the module is used in the metric system, the larger the number, the larger the gear tooth; DP is used in the imperial system, the higher the number, the smaller...
Read moreThe Pressure Angle of a Gear, as defined by JIS, is the angle between the tangent line to the tooth surface and the line from the center of the gear to the contact point between two meshing gears. Typically,...
Read morePlace the radial direction of the gear horizontally with the ground, It is right-handed if it slopes from upper right to lower left, as shown in ///; Left-handed is tilted from top left to bottom right,...
Read moreTooth height is also called whole depth. Generally the most common is the standard tooth depth (full depth teeth), the tooth depth is 2.25 times the gear module. The teeth higher than the standard teeth...
Read moreShiuh Cheng can customize the production according to the drawings provided by customers, and we can also help customers to give professional gear design suggestions in the early stage of product development. Let...
Read moreThe strength of the gear consists of two strengths, are the bending (flexural) strength and the surface durability(wear-resisting) strength. Under the same tooth parameters, the strength depends on the selected...
Read moreThe backlash of the gear is when a pair of gears mesh, the gap between the tooth surfaces. Proper backlash design is one of the key factors to smooth gear operation.The general purpose of backlash is to prevent...
Read moreTip clearance is the distance between the root circle of a gear and the addendum circle of its mate. A certain clearance between the gears is necessary for a smooth operation.
Read moreGears can meet the following two requirements through profile shift design: 1. Improve gear strength: The fewer gear teeth, the thinner root thickness and with the lower gear strength. Taking a spur...
