The invention relates to a brake mechanism of a fishing line wheel. The brake mechanism is improved on the basis of a conventional adjusting button assembly and a brake pad set positioned in the upper cavity of the line wheel, namely a planet gear mechanism positioned between the adjusting button assembly and the brake pad set is also arranged in the upper cavity; the planet gear mechanism comprises a sun gear, an inner gear, a planet gear and upper and lower cover plates; the inner gear is axially limited on the inner wall of the upper cavity and linked with the line wheel; the sun gear is sleeved on a main shaft in a loose manner, and a sun gear seat is fixed on the sun gear; one of the upper and lower cover plates is linked with the main shaft, and the other cover plate is opposite to the sun gear seat; and meanwhile, the main shaft above the sun gear seat and the main shaft below the sun gear seat are respectively sleeved with a first brake washer in a loose manner. By means of the planet gear mechanism, the friction force which acts on the line wheel is amplified exponentially, so in a limited space, a high braking force can be obtained without excessive increase in the brakepad set, and a big brake of the fishing line wheel is obtained.

The invention discloses a vertical milling lathe complex machining center which comprises a horizontally arranged lathe body (6) and a vertically arranged upright post (7). The lathe body (6) is provided with an X-axis lateral supporting line track (2) and an X-axis guide screw (5) and configured with a uniaxial rotating table (1) which reciprocates and is driven by a first outer rotor torque motor in a direct driven mode. The upright post (7) is vertically provided with a Z-axis lateral supporting line track (10) and a Z-axis guide screw (9) and configured with a crossbeam which reciprocatesup and down. The crossbeam (11) is provided with a transverse Y-axis line track (13) and a Y-axis guide screw (12) and configured with a single pendulum milling head seat frame which can reciprocate along the Y-axis guide screw (12); and a single pendulum milling head is driven by a second outer rotor torque motor at the rear part in the direct driven mode. Since a direct driven technology is applied to a B axis and a C axis, the motor torque is greatly increased and a functional part can stably operate; therefore the integral rigidity and the stability of a lathe are improved.

The invention relates to the vertical and horizontal single shaft rotary bench driven by an alternate permanent syntactic outside rotor torque motor. It directly fixes the bench on the end of the said torque motor rotor, connecting the shell with the inner cold bushing of the stator and the stator of the torque motor, with reduced middle drive linkages, improves the running precision and stability of the rotary bench, with bigger output torque and improved mechanical effect. It simplifies the braking mechanism with bigger clamping area, less drive effect with less size of the outside rotor torque motor under same performance conditions.
