1. The structure of the worm gear reducer is that a worm and the next worm gear rotate and frictionally engage to produce a deceleration effect. ② The RV worm gear reducer has two modes, one is economical with a breathable cap, and its operating environment temperature range is: -10℃-60℃, the other is precision type without breathable cap, and its use environment temperature range is -40℃-70℃.

2. Working temperature of RV worm gear reducer = ambient temperature {{1}} reducer temperature rise, for example, the ambient temperature is 30℃, and the temperature rise of reducer is 40℃, then the working temperature of RV worm gear reducer is now 30 ℃{{8}}40℃=70℃, the temperature resistance of the oil seal is 120℃, so the sum of ambient temperature+reducer temperature rise cannot exceed 120℃.

3. The worm of the RV worm gear reducer is the driving wheel, and the material used must be good. Generally, there are two kinds of raw materials: aluminum bronze and tin bronze on the market. Aluminum bronze is cheap, but has low wear resistance, low hardness, and is easy to break. The cost of tin bronze is high, and the advantages are high wear resistance, high hardness and long life. The economic type generally uses aluminum bronze raw materials, and the precision type generally uses tin bronze raw materials.

4. The transmission efficiency of RV worm gear reducer is inversely proportional to the speed ratio. The smaller the speed ratio, the higher the transmission efficiency. The larger the speed ratio, the lower the transmission efficiency. The transmission efficiency can reach 90 when the reduction ratio is 1:5. %, and when the reduction ratio is 1:100, the transmission efficiency is only 40%-50%. Therefore, the higher the transmission ratio, the more margin calculation should be reserved when selecting the model, so as to avoid the problem of insufficient torque caused by low transmission efficiency.

5. The larger the reduction ratio of the RV worm gear reducer, the more difficult the manufacturing process. Therefore, to make a larger speed ratio, 1:80 or more, the more powerful manufacturers are needed to do well.

6. The RV worm gear reducer has a self-locking function. The self-locking function actually cannot use the output end to drive the input end. To put it simply, force cannot be applied to the input end at the output end, which can effectively protect the motor at the input end.
