Type of coupling, connected with ball screw

Rigid coupling The advantage of a rigid coupling is that it can accurately transmit torque, but the requirements for the concentricity of the two shafts are very high, that is to say, the two rotating shafts are required to be on the same straight line. If the concentricity deviation is too large, it will not only affect the coupling Its performance may even affect its lifespan. Rigid couplings can be divided into the following categories: Sleeve coupling: The coupling connects two shafts in the form of a shaft sleeve. It has a simple structure, small size, and low price,

Advantages and disadvantages of motors

DC DC motor is a motor that converts DC electrical energy into mechanical energy. Because of its good speed regulation performance, it is widely used in electric drive. According to the excitation mode, DC motors are divided into three types: permanent magnet, separate excitation and self-excitation. Among them, self-excitation is divided into three types: parallel excitation, series excitation and compound excitation. When the DC power supply supplies power to the armature winding through the brush, the current in the same direction can flow through the N-pole lower conducto

The difference between ball screw and roller screw

If you need to drive an axial load of 500kN and a stroke of 1500mm, do you use a roller screw or a ball screw? If you speak of roller screws instinctively, you may not be familiar with high-capacity ball screws as an economical and simple choice. Under dimensional constraints, roller screws have been promoted as the only technical choice to deal with large loads. But in fact, technological progress has made special ball screws a candidate for high-load applications. The important thing is that under the same performance, a high-load ball screw is us
