What is the difference between the design of low speed stage gears and high speed stage gears in mec

1. The torque is different.

The torque is the lowest in the high-speed stage, and the maximum torque is in the low-to-medium speed gear.

2. The carrying capacity is different.

The modulus of the medium and low-speed gear is small, which means that the gear teeth are also relatively small, and the bearing capacity is relatively small. The modulus of high-speed gears is large. It means that the teeth are also relatively large. Its carrying capacity is also large.

3. The accuracy is different.

Teeth with small modules cannot withstand large loads.

The accuracy is small, and with the increase of the deceleration level, the modulus of the medium and low-speed gear should be selected as large as possible in order to bear the huge load.

The high-speed gear has high precision, because the low accuracy will not only cause excessive noise but also produce serious fatigue damage, as for the material and heat treatment, it depends on its load condition.

1. The torque of the high-speed stage is the smallest, and the torque of the low-speed stage is the largest.

2. The modulus of the gear is small, which means that the gear teeth are also relatively small, and the bearing capacity is relatively small.

3. The modulus of the gear is large. It means that the teeth are also relatively large. Its carrying capacity is also large.

The gear teeth of the small module can not bear the large load, and with the increase of the deceleration level, the module of the low speed stage should be selected as large as possible in order to bear the huge load.

The precision of the high-speed gear will not be low, because the low accuracy will not only cause excessive noise but also produce serious fatigue damage, as for the material and heat treatment depends on its load condition.

Hehehe, after that, Tuhu still thought.

How to distinguish between low-speed gears and high-speed gears:

1. The torque of the high-speed stage is the smallest, and the torque of the low-speed stage is the largest.

2. Regardless of whether it is coaxial or not, the strength requirements of the low-speed gear of the reducer are higher than that of the high-speed gear.

3. The gear teeth of small module can not bear large loads, the accuracy is small, and the accuracy of high-speed gears is high, because low accuracy will not only cause excessive noise but also produce serious fatigue damage.

Gear reducer function.

1. Reliable industrial gear transmission components;

2. Reliable structure combined with a variety of inputs to meet special use requirements;

3. It has a high ability to transmit power and compact structure, and the gear structure is determined according to the principle of module design;

4. Easy to use and maintain, configure and select materials according to technical and engineering conditions;

5. Torque range from 36,0000Nm to 1,200,000Nm.

In the different levels of reducers:

1. The torque of the high-speed stage is the smallest, and the torque of the low-speed stage is the largest.

2. The modulus of the gear is small, which means that the gear teeth are relatively small, and the bearing capacity is relatively small 3. The modulus of the gear is large. It means that the teeth are also relatively large. Its carrying capacity is also a big idea:

Can a small module tooth withstand a large load? That is to say, with the increase of the deceleration level, the modulus of the low-speed stage should be selected as large as possible in order to bear the huge load.

Their name is called the shaft end baffle, which is to fix the shaft, so that the shaft end does not rotate, or to fix the Xiao character inside is just a name, which does not play any practical role.

Of course, choose the envy of the slant or the herringbone.

Because of helical gear transmission.

When the contact line on the tooth surface moves along the meshing plane, that is, it enters the meshing from the top of the tooth, the contact line changes from short to long, and then from long to short, and the upper tooth is not completely detached, and the next tooth has entered the meshing, so that the load on each tooth changes from small to large, and then from large to small, so that the meshing process is smooth, and the impact, vibration and noise are eliminated.

And because the teeth are spiral-shaped, the contact line of the stool on the tooth surface in the meshing area is larger than that of the straight teeth. It can be seen that in terms of force and transmission, helical gears are better than straight gears.

I hope this brother can solve your doubts.

The low-speed grade big gear is quenched and tempered or normalized. Quenched and tempered or traced hand normalizing is widely used in general medium and low-speed gears that do not require too much strength and precision, as well as large gears that are difficult to heat treat and finish the tooth surface.

Characteristics of quenching and tempering or normalizing:

1. It has good strength and toughness after quenching and tempering, and is often used in the range of 220 300HBW;

2. When the hardness of the quenched and tempered pinion cannot be improved due to the limitation of the tool, in order to maintain the hardness difference between the posture and the size of the gear, the normalized gear can be used, but the strength is worse than that of the quenched and tempered;

3. The fine cutting of the tooth surface can be carried out after heat treatment to eliminate the distortion of heat treatment and maintain the accuracy of the gear;

4. There is no need for special heat treatment equipment and tooth surface finishing equipment, and the manufacturing cost is low;

5. The hardness of the tooth surface is low and it is easy to run and close, but it cannot give full play to the bearing capacity of the material.
