What is the classification of gear units?

The tooth profile of the reducer gear includes the reducer gear curve, pressure angle, tooth height, and displacement. Involute gear reducer gears are easier to manufacture, so in modern gear reducer gears, involute gear reducer gears account for the majority, while cycloidal gear reducer gears and arc gear reducer gears are rarely used.

What is the structure and material of the reducer gear?

The commonly used steels for manufacturing gears include quenched and tempered steel, quenched steel, carburized and quenched steel, and nitrided steel. Cast steel has a slightly lower strength than forged steel and is commonly used for large gears; Gray cast iron has poor mechanical properties and can be used for light load open gear transmission; Ductile iron castings can partially replace steel gears; Plastic gears are mainly used for light loads and low noise, and matching gears generally use steel gears with good heat transfer performance.

What are the main characteristics of precision rack?

1. Zero back clearance/High precision, unique and innovative effective meshing, always ensuring contact between two or more gear teeth, ensuring zero back clearance of two gear teeth upward, ensuring a ± positioning accuracy of 20 microns, accurately measuring the position of each gear tooth profile and the first gear tooth, to ensure extremely high positioning accuracy, and eliminating accumulated errors in tooth pitch.

Several Repair Methods for Gear Face Wear

There are four commonly used repair methods when the tooth surface of a gear is worn during the adjustment and displacement method, the displacement cutting method, the tooth insert repair method, and the surfacing repair method.

Analysis on the Development Trend of China's Gear Industry

At present, the comprehensive technical level of the transmission gear industry in China, including product quality, product design, process development, manufacturing equipment, and testing, is only equivalent to the level of developed countries in the mid to late 1990s.

Types and characteristics of gears

1. Types and characteristics of cylindrical gears Spur gear 1) The two axes of the large and small gears are parallel to each other 2) During external meshing transmission, the rotation directions of the two gears are opposite; During internal meshing transmission, both gears rotate in the same direction

What are the types of heat treatment? What's the use of each?

Gear heat treatment refers to a metal heat processing process in which materials are heated, insulated, and cooled in a solid state to obtain the desired structure and properties.

What are the advantages of hard tooth surface reducers?

Hardened gear reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical engineering, textile, printing and dyeing, pharmaceutical and other fields. Hardened gear reducer is a power transmission mechanism that utilizes a speed converter of gears to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque.

Use and maintenance of gear reducer

The mounting shaft of this machine should be cleaned before use. Check whether the installation shaft has any bruises or dirt, and if any, remove them completely. The operating temperature of the reducer is 0~40 ℃.

Installation and lubrication of cylindrical gear reducer

1. Cylindrical gear reducers generally need to be installed on a horizontal surface with an inclination of no more than 10 °. If the inclination is greater than 10 ° due to special needs, please contact our company before use to discuss relevant matters together.
