Couplings, a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. The coupling can also compensate for the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, etc.; and shock mitigation and vibration absorption.
There are many types of linear modules, and there are quite a lot of dimensions. For example, according to whether they are sealed or not, they can be divided into sealed and dust-proof linear modules and semi-closed linear modules. According to the specific requirements for the size and specification of the linear module, there are quite a few parameter indicators, so the selection of the linear module is skillful.
Linear guides are used to support and guide moving parts for linear reciprocating motion, which can achieve high-precision linear motion under high load conditions, and have a higher rated load than linear bearings. The feature is that it can move briskly without gaps when working, and can bear a certain torque at the same time, which is suitable for a variety of working environments and can maintain high precision for a long time.
Linear guides can be divided into: roller linear guides, cylindrical linear guides, and ball linear guides, which are used to support and guide moving parts and perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types.
The function of the linear guide is to support and guide the moving parts to perform reciprocating linear motion in a given direction. In order to use the right type of linear guide for the right occasion, it is necessary for the design engineer to understand the advantages and capabilities of different guides, so as to make a reasonable choice.
When using linear guide rails, some friends who are new to this kind of linear guide rails may find a strange phenomenon, that is, the guide rail sliders are locked, and the situation is still unclear for a while. Let me introduce the linear guide rail sliders. Six principles of locking: locking screw locking, cylinder clamping, clamper, locking slider, with self-locking function and guide rail is damaged.
