With the development of the industry, the output shaft type of the gearbox can no longer meet the needs of existing users. Therefore, different output shafts of the gearbox have been designed according to different user needs. Today, I will introduce the installation of the hollow shaft gearbox related information.
Advantages and disadvantages of common output shaft connectors
Output shaft with flat key
This type is the most common. It is connected with the working machine through the coupling, and the torque is transmitted through the flat key. Advantages: easy installation and maintenance, many types of couplings to choose from. Disadvantage: takes up a lot of space.
smooth output shaft
It is connected with the working machine through a keyless coupling, and the torque is transmitted through the interference between the shaft and the coupling. Advantages: simple structure, convenient processing; Disadvantages: difficult to install and maintain, and high requirements for the processing accuracy of the connection parts.
Spline output shaft
It is connected with the working machine through a special spline coupling, and the torque is transmitted through the spline. Advantages: easy installation and maintenance Disadvantages: limited choice of couplings and takes up a lot of space.
Flange output shaft
Advantages: can be quickly and easily connected with other drive components that meet the same standard, more compact appearance, larger diameter and higher torsional strength; Disadvantages: expensive.
The inner holes at both ends of the hollow shaft are tapered: the cone sleeve and the cone sleeve have an outer taper, opening along the axial direction, and the taper is the same as the inner cone holes at the left and right ends of the hollow shaft; the inner diameter is designed according to the user's shaft diameter. The structure of the hollow shaft gearbox can be multi-style, directly connected to the power shaft, flanged connection, and hollow bearing. Can save a lot of installation space;
Installation characteristics of hollow shaft gearbox
1 Reduce processing costs
When the tolerance range of the matching dimensions at both ends of the output shaft is appropriately increased and the machining accuracy is appropriately reduced, the installation and use requirements can be met, thereby reducing the processing cost of the output shaft.
2 Realize the conversion of different shaft diameters.
For gearboxs or hollow shafts of different specifications, a solid shaft with a shaft diameter within a certain range can be installed by replacing the taper sleeves at different ends. User axes can be converted between metric and imperial standards.
3Easy to install and maintain
Disassembly will not cause wear and scratches on the user's shaft and hollow shaft, and it can be easily disassembled after long-term use, which improves the work efficiency of equipment maintenance.
How to use the hollow shaft gearbox
(1) Sleeve the shaft on the hollow shaft of the gearbox;
(2) Insert the required shaft into the hollow shaft, and tighten the expansion sleeve screw;
The above is the relevant knowledge about the installation of the hollow shaft gearbox. This hollow shaft gearbox has the advantages of compact structure, good interchangeability and high transmission efficiency. It is suitable for mass and modular production, which not only makes the gearbox more adaptable and flexible, but also has great significance for improving the universality of the gearbox.
