I. Transmission principle:
Gear transmission -- mainly depends on the tooth shape of driving gear to drive the tooth shape of driven gear to achieve transmission; Worm gear drive - drive mainly depends on active worm and worm gear meshing tooth surface of sliding friction, so that the worm gear tooth surface relative movement.
Two, the advantages of gear transmission:
The reducer can transfer the motion and power between any axes in the space, that is, the axes can be parallel, cross or staggered; Smooth rotation, large transmission range, multi-stage gear transmission design, wide application range, long service life, high efficiency (89%~98%), the box is made of cast iron, beautiful appearance, compact structure. Normally, the operating temperature ranges from -10 ° C to 40 ° C. Compared with similar products, the product has the characteristics of wide speed range, compact structure and easy installation. Can be widely used in metallurgy, mining, lifting, light industry, chemical industry, transportation, construction and other mechanical equipment reducer.
Disadvantages of gear transmission:
Gear, box processing equipment, gear grinding process, assembly process and other requirements are more stringent, resulting in high manufacturing costs. Gear transmission without overload protection and self-locking performance, the need to install additional brake device, noise is relatively large, single-stage gear transmission speed ratio is small (generally not more than 1:6), and gear meshing clearance is small.
There is also a big difference between these two types of reducer:
1. Internal structure. The direct difference between the two types of reducer is their internal structure. If it is a gear reducer, the transmission structure inside is gear. As for worm gear reducer, it may be helical worm gear drive, or it may be worm gear drive. Different forms also directly affect efficiency.
2. Efficiency. The internal structure of the two kinds of reducer has a direct impact on its efficiency. If a gear reducer is used, the efficiency of any motor can reach about 90%. If the worm gear reducer is used, the transmission efficiency can reach 75%. So if you need high efficiency and energy saving, choose gear reducer is more appropriate.
