The utility model content
Problem to be solved in the utility model is in order to overcome the brake operating accident-prone defective out of control that existing greenhouse curtain rolling machine exists, roller shutter machine brake a kind of simple in structure, reasonable in design, safe and reliable to be provided.
For addressing the above problem, the utility model by the following technical solutions:
A kind of roller shutter machine brake, comprise the movable frictional disk that is installed on the decelerator power input shaft, one side of movable frictional disk is provided with a frictional disk, opposite side is provided with belt pulley, axle frictional disk and belt pulley are installed on the decelerator power input shaft, be respectively equipped with friction plate between described movable frictional disk and axle frictional disk and the belt pulley, it is characterized in that: described movable frictional disk is arranged in the braking housing, the excircle of described movable frictional disk is provided with the braking grooving, is provided with the braking roller bearing in the braking grooving.
Below be the utility model for further improvement of these options:
Described braking housing comprises the discoid base plate of fixedlying connected with the roller shutter engine housing, and a side of base plate is provided with cylindrical shell, has the gap less than braking roller bearing diameter between the excircle of described simplified and movable frictional disk.
Described axle frictional disk is fixedlyed connected with the decelerator power input shaft.
Described decelerator power input shaft is provided with screw thread, and belt pulley is threaded with the decelerator power input shaft, and described screw thread extends near the position that is installed in the friction plate between belt pulley and the movable frictional disk.
The utility model adopts such scheme, when belt pulley drives decelerator power input shaft forward rotation, braking roller bearing on the movable frictional disk in the braking grooving is in the bottom of braking grooving, movable frictional disk free state, when belt pulley stops operating, booth curtain roller is because the effect of gravity, produce pulling force downwards, the decelerator power input shaft is produced converse rotating force, make the counter-rotating of decelerator power input shaft thus, and make that relative reversing makes belt pulley near movable frictional disk between belt pulley and the decelerator power input shaft, since the effect of friction, movable frictional disk reversing, the braking roller bearing of braking this moment in the grooving moves to the top of braking grooving, because therefore the gap between the excircle of cylindrical shell and movable frictional disk, can brake movable frictional disk and belt pulley less than the diameter of braking roller bearing, thereby reach the out-of-work purpose of roller shutter machine, the utility model is simple in structure, and is reasonable in design, safe and reliable.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
