Product Specification

High Precision 20CrMnTi Spur Gears For Industrial Machinery In China 

Spur gears are the most basic and widely used fixed-axis transmission gears, with tooth traces parallel to the gear axis, mainly composed of addendum, dedendum, tooth surface, pitch and other structures. Made of high-quality steel through precision machining and heat treatment, they have a simple structure and reliable transmission. They are mainly used for power transmission and speed change between parallel shafts, realizing speed reduction, torque increase and speed increase transmission, and adapting to light load, medium load and some heavy load working conditions. Widely used in industrial machinery, automobiles, agricultural machinery, electric tools, automation equipment and other fields, they are indispensable basic components in mechanical transmission systems.

Product Features

• Tooth traces are parallel to the axis, with simple structure, mature processing technology and low production cost.
• Stable transmission, suitable for parallel shaft forward/reverse transmission, with accurate and constant transmission ratio.
• Line contact during meshing, uniform force, stable load-bearing performance, suitable for light and medium load conditions.
• Controllable precision, which can be processed into ordinary precision and precision according to requirements, adapting to different scenarios.
• Easy installation, no complex positioning, strong interchangeability, easy maintenance and replacement.
• The tooth surface can be strengthened, wear-resistant, fatigue-resistant and long service life.
• No axial force is generated, which has small load on bearings and reduces the operation loss of the whole machine.
