When the vertical reducer (Retarder) is used for agitation, it is usually equipped with a frame, such as a JXLD gear (Gear) reducer bracket, and a type A worm gear reducer. How can the vertical reducer bracket structure be more reasonable?

When the vertical reducer (Retarder) is used for agitation, it is usually equipped with a frame, such as a JXLD bracket, a type A worm gear reducer, and an M type reducer. How can the vertical reducer bracket structure be more reasonable?

Unreasonable design of the line pin wheel frame structure 1) Calculated by (tōng guò) the speed reducer (Retarder)

      The axial force of the first and second shafts is very large, and the spherical roller bearing of the cylindrical hole is mainly subjected to radial load and can only bear a small amount of bidirectional axial load. Gear motor

1、R series coaxial helical gear reducer is manufactured in accordance with international technical requirements and has high technical content.

2、Space saving, reliable and durable, with high overload capacity, power up to 132KW;

3、Low energy consumption, superior performance, and the efficiency of the reducer is over 95%;

4、Low vibration, low noise and high energy saving;

5、The high-quality forged steel material and the steel cast iron box are used, and the surface of the gear is subjected to high-frequency heat treatment;

6、After precision machining to ensure the parallelism of the shaft and the requirements of the positioning bearing, the reducer that forms the helical gear transmission assembly is equipped with various types of motors, which are combined into mechatronics, which fully guarantees the quality characteristics of the products.

2）The bearing of the spherical roller bearing cannot be adjusted. If the assembly is assembled according to the requirements of the drawing, the axial end of the bearing is equal to the bearing after the fixed end cap is tightened. The axial clearance of the bearing, while the axial clearance of the spherical roller bearing is approximately 4 to 7 times that of the radial clearance. The axial clearance is quite large. As can be seen from the SKF manual, the common grade is 23938CC/W33, 2404 (dead page) The radial original clearance of the 0CC/W33 bearing is 0.13~0.2mm, and the radial original clearance of the 23222CC/W33 bearing is 0.075~0.12. Although the radial clearance is slightly reduced after installation, the axial direction is The gap, that is, the axial runout is still large, and the spiral bevel gear (tabear) is the most taboo of the large axial runout. The efficiency of the hardened gear reducer drive is the most efficient of all drives, and its efficiency is much higher than that of the worm drive. The efficiency of the gear reducer is mainly determined by the friction of the gear and the bearing.

3） When the spiral bevel gear (Gear) is installed, it is positioned by the method of aligning the bevel gears to the back cone surface. Under the transmission load of the heavy-duty transmission gear pair, the most important factor (factor) of the influence bearing capacity is the wheel. The shape and position of the tooth contact, because the direction of the axial force is directed to the big end during operation, the two bevel gears have a separate trend. Under the large axial force, the spiral bevel gear will have an axial direction. When moving, the tooth contact area will move toward the root and the top of the tooth, and there will also be a movement along the length of the tooth due to the longitudinal curvature, and the contact area will move toward the end of the gear. The spiral bevel gear is most afraid of the end. Contact, especially big end contact, because long-term end contact can cause early failure of the gear, or even broken teeth. Gear reduction motor uses all kinds of gear transmission to achieve the purpose of speed reduction. The reducer is composed of gear pairs of various stages. For example, the gear can be driven by a small gear to achieve a certain speed reduction, and then adopt a multi-stage structure. It can greatly reduce the speed.4）因为2

       V, 4V often has a blank phenomenon, and only has to reverse the steel. In the reverse direction, the axial force directions of the two axes point to the small end of the bevel tooth. The passive axis is already at the lowest position due to gravity, so the drive shaft The spiral umbrella moves inward, and the active tooth convex contact area moves to the top and the big end, and the normal backlash of the tooth contact is reduced. Since the bearing axial gap is too large, the tooth The backlash may even be 0. This is particularly dangerous and can cause broken teeth. In summary, it is recommended to change the spiral bevel gear (Gear) support to two single-row tapered (Tapered) roller bearings back-to-back arrangement, so that it can withstand large axial forces, and the radial and axial clearances can be adjusted, and The back-to-back arrangement axial thermal expansion (inflate) offsets each other.
