Described brake assemblies screens groove is one or more.

The top and the bottom that between described rotating shaft outer ring and rotating shaft inner ring, form annular space are respectively arranged with seal ring.

Described brake assemblies is air bag brake assemblies.

Described brake assemblies is electromagnetic brake assembly.

Working principle: one, the attachment hole of four fixing brake assemblies is the standard interface of air bag brake or electromagnetic brake, the alternative air bag of installing brakes or electromagnetic brake, and fixes by brake assemblies screens groove and rotating shaft inner ring; Two, on the flange of rotating shaft inner ring, be provided with some mechanical brakes hole, meet the needs that mechanical brake is installed; Three, be provided with spacing index hole for mounting limit piece, be used in conjunction with the limited post of installing, control the angle of the rotation of rotating shaft; Four, be provided with seal ring, can extend the working life of lubricating grease.

Beneficial effect of the present invention: one, the rotating shaft of a kind of multifunctional modular rotating shaft of the present invention and flange adopt Integral forge type, have omitted and have been threaded, and have improved bulk strength, make rotating shaft in use more pacify body; Two, a kind of multifunctional modular rotating shaft of the present invention can be installed mechanical brake, and also alternative air bag brake and the electromagnetic brake installed, meets the needs that various brakes are installed; Three, a kind of multifunctional modular rotating shaft of the present invention adopts embedded mode that limiting stopper and limited post are set, make easy to process, compact overall structure, meanwhile, the simplicity of design of bounding means, economy; Four, a kind of multifunctional modular rotating shaft of the present invention is provided with seal ring, has extended the working life of lubricating grease, has reduced and has leaked; Five, the overall dimensions of a kind of multifunctional modular rotating shaft of the present invention and weight all reduce, and global design modularization reduces the time that rotating shaft is assembled, and has improved utilization efficiency.
