Proper motor shaft alignment increases the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate within their acceptable design limits.
While misalignment has no measurable effect on motor efficiency, correct shaft alignment ensures the smooth, efficient transmission of power from the motor to the driven...
In linear and sliding motion mechanisms, a linear shaft rod plays a crucial role. Without a linear shaft, we wouldn’t complete a sliding mechanism with linear power transmission.
But, the manufacturing and choosing of the appropriate linear shaft can get tricky. Linear shafts can have different structures and be made of various materials, depending on the properties needed.
So,...
It is applied to the motor shaft in many machines. It is generally made by rolling round steel or forgings through its cutting. If the required shaft diameter is relatively small, it can be processed with round steel bars. If the shaft is relatively large, The diameter of the steps varies significantly and can be machined using forgings. In order to save raw materials and improve...
The spline shaft is a kind of mechanical transmission. The flat key, half-circle key, and oblique key have the same function to transmit mechanical torque. There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways to keep Rotate synchronously with the axis. While rotating, some can also slide longitudinally on the shaft,...
Because it is integrated with the electric motor, the Electric Spindle Shaft itself can also be regarded as a high-speed electric motor. There can be many different structural methods, such as induction motors, permanent magnet motors and reluctance motors. The key skill is the dynamic balance at high speed.

Transmission Shaft is an Element Used to Transmit Power and Torque
A transmission shaft is a component used to transmit power and torque. Shafts are made in a variety of different shapes and forms, but most tend to have a solid or tubular circular cross-section. The shaft transmitting power directly from the drive device or power source to the load. The shaft can carry gears, pulleys and...
The spindle shaft is a motion shaft that drives the tool or workpiece to rotate on the machine tool to produce cutting motion. According to the driving mode of the spindle shaft, the machine tool spindle can be divided into two categories: mechanical spindle and electric spindle.
The mechanical spindle shaft drives the spindle shaft to rotate through the spindle shaft motor and the...
The drive shaft is a rod-shaped component that transmits torque from the vehicle's engine to the wheels. Essentially it is the axle that drives the vehicle. The transmission shaft transmits torque between the transmission system components at different angles. The shaft assembly must be flexible, which is important because the shaft of the transmission system vibrates up and down and moves...

The shaft is an important part of the motor, as the link of electromechanical energy conversion between the motor and the equipment, supporting the rotating parts, transmitting the torque and determining the relative position of the rotating parts to the stator. Therefore, the motor shaft must have reliable strength and rigidity to ensure the realization of the preset design function....
Coated fabric is a kind of fabric treated by a special process. It can form a uniform layer of covering rubber on the surface of the fabric to increase the waterproof, fireproof, and antifouling functions of the fabric. For aesthetics, this kind of clothes is brighter than ordinary clothes.
The coated fabric uses solvent or water to dissolve the required coating particles, such as PU glue, A/C...
The linear shaft is a connecting part that supports the work of the piston. Most of it is used in oil cylinders and cylinder motion execution parts. It is a moving part with frequent movement and high technical requirements. It is composed of a cylinder, linear shaft (cylinder rod), piston and end cover. The quality of its processing directly affects the life and reliability of the entire...

Electric Spindle Shaft is more compact than Mechanical Spindle Shaft, modular structure, easy to install. However, Electric Spindle Shaft is more prone to vibration than traditional timing belts and V-belt spindles. After all, traditional spindles can eliminate the vibration of the motor through the flexible belt. Furthermore, the Electric Spindle Shaft generates more heat. The heat dissipation...
From the point of view of use, the servo motor is mainly responsible for the feed of the machine tool, so that the workpiece moves to the tool or the tool moves to the workpiece, which is mainly to realize the cutting work, which requires relatively high torque and control accuracy; and the spindle motor is mainly responsible for driving the machine The main shaft drives the workpiece or the...
