Introduce the principle and use characteristics of copper worm gear

The lead angle of the copper worm gear is the angle between the tangent line of the helix on the worm index cylinder and the end surface of the worm. The relationship with the screw helix angle is that the larger the helix angle of the worm wheel, the higher the efficiency of the copper nut. The following describes the principle and use characteristics of copper worm gears:

  The principle and use of copper worm gear: Copper worm gear transmission principle: The copper worm gear transmission is used when the two shafts of the copper turbine cross at 90 degrees, but they are neither parallel nor intersect each other. Usually in the worm gear transmission, the worm is the active part , And the worm gear is a passive component.
Copper worm gear reducer is a wear-resistant block transmission machine with compact structure, large transmission ratio and self-locking function under certain conditions. Among them, the hollow shaft type worm gear reducer not only has the above characteristics, but also has convenient installation and reasonable structure, and has been more and more widely used. It is to add a helical gear reducer to the input end of the worm gear reducer, the multi-stage reducer can obtain a very low output speed, which has higher efficiency than the single-stage worm reducer, and has low vibration, noise and energy. Low consumption. The main gearbox of the elevator is made of steel and copper matching copper worm gear reducer, so ordinary gear oil cannot be used, but only special worm gear oil, which has no corrosion to the copper turbine.
Many gear oils contain sulfur additives. Under boundary lubrication conditions, this additive can chemically react with the metal elements on the gear surface to prevent serious sintering of the two friction surfaces. However, while preventing metal-to-metal contact under boundary lubrication conditions, sulfur-based additives are corrosive under certain conditions, especially for yellow metals, such as copper, brass, bronze, etc. These are commonly used in industrial worm gears and other components In terms of metal materials. The best way to choose the right product is to have a comprehensive understanding of gear types, materials and operating conditions. Choose the correct lubricant according to the equipment load, operating speed, operating temperature and other requirements.

The copper worm gear drive has the following characteristics:

1. Large transmission power range
2. Work smoothly and without noise
3. The structure is compact, and a large transmission ratio can be obtained. The general transmission ratio is 7-80.
4. The transmission efficiency is low, and the worm gear is often made of non-ferrous metals. The spiral of the worm can be divided into single-end and multi-end.
  The calculation of the transmission ratio is as follows: I=n1/n2=z/K n1-rotation speed of worm n2-rotation speed of worm wheel K-number of worm heads Z-number of teeth of worm wheel.
