Arrester for roller door, roller shutter etc. lifting drive - whose hub has two firmly coupled brake hubs with rotary cam disc in between
The arrester incorporates a hub, corotatably joined to the lifting gear to drive a ratchet wheel, using a speed-controlled release which at overspeed causes a pawl to engage the ratchet and cutout the drive power. The hub (11) has a corotatably connected two brake hubs (16,17) and rotary cam disc (2...

| description | The arrester incorporates a hub, corotatably joined to the lifting gear to drive a ratchet wheel, using a speed-controlled release which at overspeed causes a pawl to engage the ratchet and cutout the drive power. The hub (11) has a corotatably connected two brake hubs (16,17) and rotary cam disc (22) between the two hubs. - Cam faces (20,22) round the disc engage one another with humps and recesses in the free-sheel setting, with the cam disc fixed to the ratchet wheel (23). The two brake humbs diverge on the arrester hub axially against a spring, when adjoining cam faces ride onto one another and the ratchet is blocked. The brake hubs have friction surfaces (18), which work with friction surfaces (19) on a housing (1), when the hubs move apart.

The hub (11) has a corotatably connected two brake hubs (16,17) and rotary cam disc (22) between the two hubs.
