There are many different types of gear reducers and worm gear reducers on the market, and they are used for different purposes.Many people will say, why are the performances and uses of the products different?The following briefly introduces the different principles of gear reducer and worm reducer.
1. Principle of gear reducer
On the basis of the modular combination system, the gear reducer can be combined with ordinary, brake, explosion-proof, frequency conversion, servo, IEC and other motors and can be installed in six directions in three-dimensional space.This product is widely used in textile, food, beer and beverage, chemical industry, escalator, metal processing, paper making, crane, plastic machinery, wood processing, automatic storage equipment, metallurgy, tobacco, environmental protection, logistics and other industries.The input power range of this series of reducers is 0.12KW ~ 200KW, the allowable single-pole torque is 55000NM, and the single-pole transmission ratio is 3.81~267.43.
Second, the principle of worm gear reducer
The worm gear reducer is a cylindrical worm with an arc-shaped shaft section, and the tooth profile of the worm gear is conjugate to the worm.Since the worm gear and the worm are in concave meshing, most of the meshing area has a larger comprehensive curvature radius, which reduces the stress on the tooth surface, increases the strength of the tooth surface, and improves the bearing capacity.At the same time, the tooth shape reasonably reduces the tooth thickness of the worm and increases the root thickness of the worm wheel.Therefore, the bending strength of the tooth root of the worm gear increases, the transmission capacity increases, 40°-90° liquid lubrication is easily formed, the friction coefficient between the tooth surfaces is small, the efficiency is high, and the temperature is low.
Worm reducer products are widely used in ceramics, food, tobacco, woodworking machinery, pharmaceuticals, textiles, leather, machine tools, glass, lifting, lifting, transportation, environmental protection, chemicals, papermaking, packaging, warehousing and logistics, fluid equipment, beverages, plastics Machinery, three-dimensional parking, automobile manufacturing, printing and dyeing machinery, power cable machinery and other industries, are well received by users.
The input power range of this series of reducers is between 0.06KW and 7.5KW; the output torque: 2.6NM-1800NM; the rotation speed of the input shaft is generally not more than 1500 rpm; the high-speed shaft can run in both directions; the working environment temperature is -40 ℃～45℃; when the working environment temperature is lower than 0℃, the lubricating oil must be heated above 0℃ before starting.
The gear reducer has a higher efficiency during use, up to 98%, while the worm gear reducer reaches 65%-70%.The gear reducer cannot be self-locking, and the worm gear is self-locking.Moreover, the radial force and axial force of these two reducers are different, so the gear reducer is different from the worm gear reducer.
