Chapter 251 Reducer
Regardless of the type of reducer, it is used at the joint, but even at the joint, it is used at different joints according to the characteristics of each reducer.

For example, RV reducer, because this kind of reducer performs better in rigidity and rotation accuracy, it is generally used in the boom, machine base, shoulder and other places that need to bear relatively large forces.

On the contrary, we can guess that the harmonic reducer is mainly used in places that bear less force, such as the hand, such as the forearm, such as the wrist and so on.

The RV reducer and the harmonic reducer are corresponding and complementary to each other. One is used where the force is large, and the other is used where the force is small.

The proportion of the reducer in all the manufacturing costs of the entire robot is still relatively high, almost close to one-third. From this price, we can see the importance of the reducer.

After all, a large part of the accuracy of the robot is determined by the reducer.

For example, enter a program to let the robot move forward one meter, and the robot will move forward after receiving the command, but how to judge the distance of one meter after moving forward one meter still depends on hardware.

Both software and hardware are very important. Only when software and hardware cooperate with each other can we create better robots.

Both are indispensable.

It can be said that the reducer has been monopolized by the island country. As long as it is a monopoly industry, there is no one that is not profitable, and it is still highly profitable.

Island people also sell the same product at different prices according to different customers, which is completely opposite to Zhang Xingchen's business philosophy.

For example, if we sell to some stable large customers, the price will reach about [-] per reducer due to the large purchases, but what about our purchases?

The price has to reach 7 yuan, and this is a company with a relatively good relationship.

I don't know if there are other factors besides business involved.

I only sell you 7 yuan if you have a good relationship. What if the relationship is average?

Sorry, it will be more than 12, about [-].

There are also many companies that make reducers in our country, such as Haicheng Qibu, Liujiang Tairong, Sixi Jinxing, etc. The reducers they make are not bad, but compared with the reducers in island countries, then It's a little bit close, almost equivalent to the level of the island country in the 80s.

Almost 40 years behind.

For things like technology, precision, mechanical equipment, and precision parts, part of the improvement is based on the front, part of it depends on talents, and part of it depends on the accumulation of time.

People have developed hundreds of years ahead of schedule, and it is not that they can surpass it within a few years through hard work.

Overtaking on a curve?

Most likely a rollover.

To do technology, you need to be down-to-earth. If you don’t have some, you don’t have to rely on a few ppts.

Isn't that right, Jia.

Don't think about always working hard on publicity, just make a gorgeous appearance?
How about lying to yourself?

No, it is to tell a good story to deceive those stock investors, to deceive those leeks.

People still need a little conscience.

To be honest, relying on the current research capabilities of the company, it is impossible to catch up with the island country in terms of speed reduction, and it will not be impossible for a few decades, but with the addition of Xingchen Company, it will be different.

Once Xingchen Company makes a move, it is not just catching up, it can be said to surpass it.

To evaluate whether a reducer is good or bad, it mainly depends on these three places, namely accuracy, life, and impact resistance.

Some reducers can meet the precision requirements when they are manufactured, but the wear rate is really poor. Others can use them for ten years, but yours can’t be used after only one year. Who do you think customers should buy?

The effective life of the reducer is very important.

According to the test, the reducer produced by the island country company can last for [-] hours without problems, while the reducer produced by other companies can only be used for [-] hours without problems.

The gap is still a bit obvious.

Most RV reducers are composed of planetary brackets and cycloidal pinwheels, so that the volume of RV reducers is relatively small, and the effective space occupied is also relatively small, followed by The quality is relatively light.

Generally speaking, the range of the transmission ratio of the RV reducer is relatively wide, and the reduction ratio is also large, resulting in a large torque, so it is more suitable for larger places.

Moreover, the RV reducer has very strong stability, high precision, accurate positioning, and low error rate, which leads to high work efficiency, and it is very strong, can effectively resist impact, and has strong tolerance. The combination of these factors makes RV The life of the reducer is very high.

The RV reducer has a deceleration mechanism and an acceleration mechanism, so that the acceleration and deceleration applications are free and can be switched back and forth. The deceleration mechanism is realized by spur gears, and the acceleration mechanism is realized by differential gears.

As for the main components of the harmonic reducer, there are four parts, which are wave generator, flexible gear, rigid gear and bearing.

It can be seen that there are gears on both the RV reducer and the harmonic reducer. It can be said that the key part of the reducer is the gear.

But this is not a problem for Xingchen Company at all.

Soon, under Zhang Xingchen's command, the reducer was produced in the past two weeks.

If it’s still not working after it’s finished, we need to test its performance, such as impact resistance test, such as flexibility test, such as durability test.

Other experiments are easy to say, the most important thing is that the durability experiment takes up the most time.

But it doesn't matter, the robots made by Zhang Xingchen are used by themselves now, and they are not ready to be sold outside, so this durability experiment directly searches for data in actual combat.

The meaning of this sentence is to directly apply it to the robots produced by Xingchen Company, let them work directly, and collect data at work.

In this way, the data is more effective and more real.

"Consume the reducer of the island country, no longer place an order for the reducer of the island country, and switch to our own reducer immediately after consumption is complete."

Zhang Xingchen gave the order.

The island country reducer still has a lot of inventory, which is bought with money. Although it has researched its own reducer, it is still consumed based on the principle of not wasting.

After all, it still takes up space in the warehouse.

In fact, Zhang Xingchen is very relieved about the reducer he produced, knowing that there must be no problem with the durability test, but for the sake of insurance, he does not sell it to the outside world.

If the use time of the reducer reaches the time specified in the durability test, it is necessary to consider whether it needs to be sold externally.

Even if it is for external sales, Zhang Xingchen does not plan to sell in large quantities.
