To initiate engagement, the clutch shoes are moved outwards into pressure contact with the rotating drum air thrusters built into the driven half hub.\u003c\/p\u003e\n\n\u003cp\u003eThis starts the driven half rotating, and as it accelerates the centrifugal effect causes the clutch shoe assemblies to press harder against the drum, giving progressively firmer engagement until after a few seconds the starting air pressure can be removed.\u003c\/p\u003e\n\n\u003cp\u003eWhen up to operating speed the clutch transmits normal power, being \"locked up\" by centrifugal force and therefore operates without further slip.\u003c\/p\u003e\n\n\u003cp\u003eShould an overload occur sufficient to cause clutch slip or to slow the prime mover significantly, the clutch disengages immediately protecting the transmission from the high inertia torque which would otherwise be applied by the rotating masses of the engine, electric motor or turbine rotor.\u003c\/p\u003e\n\n\u003cp\u003eClutch disengagement (if required) makes use of the this feature. It is effected by a disc brake operating on the driven hub. Thus, when the driven machine is stationary, it is also secured against rotation by the brake. This is an essential requirement in marine propulsion or wherever the load can drive back, as in centrifugal pumps.\u003c\/p\u003e\n\n\u003cp\u003eThe disc brake is necessary if the clutch has to be disengaged whilst the machinery is running or if the driven shaft must be held stationary whilst the clutch is disengaged. (If the driven shaft can be rotated by the load, it will try to engage the clutch, making a brake essential).\u003c\/p\u003e","brand":"Twiflex","offers":[{"title":"Default Title","offer_id":57383882064254,"sku":"TWIFLEX-AIRSTARTCLUTCH","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/8689\/2670\/files\/sparepart_7f8a19ba-4c70-45c7-b961-91d4db37a5ce.png?v=1778339272"},{"product_id":"twiflex-flexi-clutch","title":"Flexi-Clutch","description":"\u003cp\u003eSkip to main content Enable accessibility for low vision Open the accessibility menu\u003c\/p\u003e\n\n\u003cp\u003eFlexi-Clutch A set of weighted lined shoes are carried by flexible cylindrical blocks in a central hub, permitting appreciable deflection under load, thereby imparting the low torsional stiffness characteristic which is an important feature of this design.

The driven member is in the form of a drum and the driving member a hub to which lined shoes are connected via pairs of links and rubber bushes. The rubber bushes can be set to control the speed at which the shoes commence to engage, provide frictionless non-wearing pivots and also deflect to accommodate misalignment thereby enabling the clutch to 'double' as an efficient flexible coupling. Link Clutch Specification Link clutches are supplied with spring restraint when uncoupled engine idling is needed, and in most cases will provide sufficient torsional flexibility and damping.
