Mechanical safety technology: dangerous parts of mechanical equipment and protective measures

2026,01,09

1） Dangerous parts of mechanical equipment

Mechanical equipment can cause various injuries such as collisions, pincers, cuts, and entanglements.

The meshing points between rotating components and between rotating components and fixed components;

Proximity type;

By type;

Unidirectional sliding.

（2） Safety protection measures for mechanical transmission mechanisms

The common transmission mechanisms on machine tools include gear meshing mechanisms, belt transmission mechanisms, couplings, etc. It is necessary to protect the dangerous parts of the transmission mechanism.

The safety technical measures taken are generally divided into three categories: direct (during design), indirect (protective devices), and directive (safety regulations, setting signs).

Safety protection of gear transmission. The gear transmission mechanism must be equipped with a fully enclosed protective device, and cannot be used without a protective cover;

Safety protection of belt drive. The protective cover of the belt transmission device can use a metal skeleton protective net; The protection of the belt transmission mechanism can be achieved by covering the entire belt or by using protective railings.

Safety protection of couplings. The safety requirement for the coupling is that there is no prominent part, that is, the use of a safety coupling; The fundamental solution is to add a protective cover, the most common of which is an Ω - shaped protective cover.
