In order to integrate into the fierce market demand and provide stronger service to the Chinese metal manufacturing industry, the design scheme of the wire drawing machine transmission device has also changed to the transmission system of hard toothed gears. The main manifestation is that at present, the sales market has already selected a large number of ultra strong narrow V-belt combined with a dedicated hard toothed reducer for wire drawing machines, and a standardized reducer integrated into the overall structure of the wire drawing machine is selected, And the reducer is reasonably integrated with the installation shell, main shaft bearing, steel wire rope drum, etc. to produce a set of wire drawing machine transmission device with hard tooth surface gears as the key transmission system.
Compared with quadratic linear WPWKA60,WPWKA70,WPWKA80,WPWKA100,WPWKA120 worm gear pairs, standardized hard tooth surface reducers have the following advantages: 1. High efficiency and strong bearing capacity of the transmission system; 2. Convenient preparation and convenient composition; 3. Easy installation; 4. The cost fee is valid; 5. Can complete parameterized design; 6. Long term trends, etc.
The hard tooth reducer adopts helical transmission gears, with an efficiency of 0.95-0.98 when engaged in the rain shower system, The basic theory is that the transmission output power is relatively large, with a rate of 50000kw; v/(m/s)<=130. For quadratic linear worm gear pairs, with high machining accuracy and excellent lubrication conditions, the maximum efficiency of the transmission system can only reach 0.95. However, in general worm gear transmission, its high efficiency generally ranges from 0.70 to 0.92. Due to the limitation of heat, the larger transmission output power Pi (kw)=750, but generally At present, high-speed and large-sized wire drawing machines have become popular in the sales market. Among them, high-power electric motors are widely used on large-sized wire drawing machines. Choosing a high efficiency hard tooth gear transmission system will generate good economic benefits for customers and have excellent sales market estimates.
There is a positive correlation between the reduction ratio and the transmission output power, but the larger the reduction ratio, the greater the management center distance between the transmission gears. The characteristics of large-sized wire drawing machines depend on the large diameter of the pulling cable, large pulling force, and high required pulling output power, which can cause excessive casing.
Under the same reduction ratio, selecting a transmission gear can moderately increase the proportional progression of the transmission system in order to achieve the estimated transmission ratio. However, due to the hazards of its installation method (limited by lubrication standards and only horizontal installation), the worm gear and worm gear pair can only choose a very large shell structure.
