Abstract

The invention discloses a mechanism with double degrees of freedom. The mechanism comprises a shell and a band-type brake device. A linear motor and a direct-drive rotary motor are arranged in the shell, the linear motor comprises a linear motor stator, a linear motor rotor and a self-lubricating bearing, the linear motor stator is arranged in the shell, the linear motor rotor penetrates the self-lubricating bearing and the linear motor stator and is in clearance fit with the linear motor stator, the direct-drive rotary motor comprises a rotary motor stator and a rotary motor rotor, the rotary motor stator is arranged on the shell, the rotary motor rotor is clamped on the shell and is positioned between the shell and the rotary motor stator, a rotary bearing is arranged in the shell and is butted to the rotary motor rotor, a spline housing is arranged in the rotary motor rotor, the linear motor rotor penetrates the spline housing, the band-type brake device is arranged on the linear motor rotor, and the linear motor rotor can be locked or released by the band-type brake device. The mechanism has the advantages that intermediate transmission mechanisms can be omitted, the mechanism is provided with the band-type brake device, and accordingly precision and speed control can be effectively improved.
