This paper introduces the principle and its use copper worm gear and worm
Lead Angle is motion slide and worm and worm indexing of cylindrical spiral line on the Angle between the tangent and worm end face, and the screw helix Angle, on the relationship of worm gear spiral Angle is the copper nut with high efficiency.Here are copper worm gear and worm principle and use features:

Oilless Dry Bushings and worm principle and use: the copper worm gear and worm drive principle: copper worm gear and worm drive is used for copper turbine shaft intersect into 90 degrees, but are neither parallel nor intersect with each other, usually in the worm gear, worm is active, and worm gear is passive.

Copper worm gear and worm reducer is a kind of compact structure, large transmission ratio, under certain conditions which has the function of self-locking wear-resisting block transmission machinery.The hollow shaft type worm gear reducer is not only has the characteristics above, and convenient installation and reasonable structure, get more and more widely used.It is in the worm gear and worm reducer input with a helical gear reducer, consisting of multistage speed reducer can obtain very low output speed, than the single-stage worm gear deceleration machine has higher efficiency, and little vibration, low noise and energy consumption.Elevator host gear box for steel copper matching copper turbine worm reducer, so can not use the ordinary gear oil, and used only for turbine worm, no corrosion to copper turbine.

Many gear oil additive containing sulfur type, under the condition of boundary lubrication, the additive can react with metal elements on the surface of the gear to prevent serious sintering friction surface of two.But under the boundary lubrication condition to prevent metal to metal contact at the same time, under certain conditions is corrosive sulfur type additive, especially for the yellow metal, such as copper, brass, bronze, the worm gear and worm in industry commonly used for metal materials and other components.The best way to choose the right product is to the type of gear, material and operating conditions have a comprehensive understanding.According to the load, operation speed, operating temperature, and other requirements to select the correct lubricant.

Copper worm gear and worm drive has the following features:

1. Large range of transmission power 2. Work smoothly without noise 3. Compact structure, and can obtain large transmission ratio, average ratio of 7-80.4. The transmission efficiency is low, the worm gear often need non-ferrous metal manufacturing.The worm screw has a single head and long.The calculation of transmission ratio is as follows: I = n1 n1 n2 = z/K - the speed of the Sintered bronze washer disc,oilite thrust washer n2 - worm gear speed K - - the number of teeth on the worm gear and worm capita z.
