A gear coupling is a mechanical device for transmitting torque between two shafts that are not collinear. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle.
Each joint consists of a 1:1 gear ratio internal/external gear pair. The tooth flanks and outer diameter of the external gear are crowned to allow for angular displacement between the two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are called gears because of the relatively large size of the teeth.
Gear couplings and universal joints are used in similar applications. Gear couplings have higher torque densities than universal joints designed to fit a given space while universal joints induce lower vibrations. The limit on torque density in universal joints is due to the limited cross sections of the cross and yoke. The gear teeth in a gear coupling have high backlash to allow for angular misalignment. The excess backlash can contribute to vibration.
Gear couplings are generally limited to angular misalignments, i.e., the angle of the spindle relative to the axes of the connected shafts, of 4-5°. Universal joints are capable of higher misalignments.
The internal gear-shaped elastic coupling is the latest product in China and has been EPG Machinery is located in XiHu Area HangZhou Zhejiang ,China. It is 30km from our factory to HangZhou international airport. widely used in foreign countries. This product is designed by the Jinan Foundry and Forging Machinery Research Institute of the Machinery Commission. It is suitable for flexible transmission between shafts and allows for larger shafts. Radial displacement and angular displacement, and has the advantages of simple structure, convenient maintenance, easy assembly and disassembly, low noise, small loss of transmission efficiency, long service life, etc., and is popular among users. The shaft hole type has a cylindrical shape (Y), a conical shape (Z), and a short cylindrical shape (J). The shaft hole and keyway are processed according to the national standard GB3852-83 “Coupling shaft hole and keyway form and size”. The working temperature is -20 ~ +70 °C.
The semi-coupling is made of precision casting, cast iron HT20-40, cast steel ZG35II, shaft hole and keyway are made by drawing. The inner toothed coupling elastic body jacket can be made of various hardness synthetic rubber grease rubber according to user requirements; Reinforced materials such as cast nylon elastomer. In order to meet the needs of various mechanical renovations and the introduction of spare parts for equipment, our company can provide internal gear-shaped flexible couplings with complete specifications and specifications, and can accept non-standard orders according to user needs.
