Gear is an important part of gear wpds60 reducer. For gear wpds60 reducer, gear plays an important role. If a good gear is used, the advantages brought to the gear wpds60 reducer are as follows:
1) High efficiency in the common mechanical transmission, the gear transmission efficiency is higher, and the closed transmission efficiency is 96% ~ 98%, which is of great economic significance for high-power transmission.
2) Compact structure, smaller space than belt and chain transmission.
3) Stable transmission ratio is often the basic requirement for transmission performance. Gear transmission is widely used because of its characteristics.
4) Reliable operation and long service life. Gear transmission with correct and reasonable design and manufacture and good use and maintenance can work very reliably and have a service life of up to ten or twenty years, which is unmatched by other mechanical transmission.
The gears constituting wpds60 reducer are divided into helical gear and spur gear. Why are the gears of many gear wpds60 reducers inclined? We can draw the reason by comparison.
1. Compared with spur gear, helical gear reducer shaft position is more free. For example, the differential transmission shaft with oblique bevel teeth does not have to be on the same horizontal plane as the rear axle. It is necessary if it is straight bevel teeth.
2. Reduce noise. If the gear reducer uses helical teeth, the noise will be much lower than that of straight teeth at the same speed. The reason is that the surface of helical teeth of gear reducer is first point contact, then transition to surface contact and * to point contact. The of spur gears is line surface line contact. The transition of helical teeth is smoother. Therefore, the noise caused by the sudden change of contact is much smaller than that of flat teeth.
3. Helical gears have a large degree of coincidence and many teeth enter the mesh at the same time. Reduce impact and noise, make the transmission more stable, and can withstand high-speed and heavy load.
4. In the process of machining, there are few undercuts and small number of teeth to avoid undercutting. The corresponding gear head is small, so the volume of the gear reducer with helical gear is small when the transmission ratio of the transmission pair is the same.
5. The production is convenient. A group of helical gear reducers with the same teethnumber and modules and different face widths can be produced on the cylindrical blank with the gear hobbing machine. In the later stage, they can be cut into different face widths according to the needs of customers.
However, the transmission of spur gear has poor stability, large impact and noise. The helical gear transmission of gear reducer has large coincidence degree and good tooth surface contact, so the bearing capacity is high; The number of small teeth of helical gear is smaller than that of spur gear, so the mechanism is more compact and the manufacturing cost is the same as that of spur gear. It is more reasonable to use helical gear in gear reducer, which is suitable for engineering practice.
Helical gear reducer has so many advantages, but its advantages are based on * * * manufacturing, exquisite surface treatment and exquisite tooth shape correction. Therefore, precision electromechanical has been committed to working hard in technology and technology, and strive to manufacture more * * * and exquisite gear reducer.
