Locking Assembly
Locking Assembly
Power Ace Engg Co offers premium quality Locking Assembly, manufactured by TAS-Schafer, Germany, one of the leading manufacturers of premium quality internal and external locking devices. The product quality is certified by EN ISO-9001: 2000 – Germany. This is a device which locks the shaft with the hub for further manufacturing activity. These are meant for highly stressed shaft-hub connections. This was earlier done by the age old keyway system of locking. In a keyway system a slot has to be made on the shaft as well as on the hub and a key (metal piece) has to be inserted between slots on shaft and hub in order to lock both, so that they rotate together. This process involves machining the shaft and the hub, inserting the key, then, hammering the shaft in the hub with the key or vice versa. The locking devices eliminate machining of the keyway on shaft and the hub, hammering is not required any more. These are inserted between the shaft and the hub only by tightening of bolts, locking them with each other and rotating together. They are a superior solution for mounting, repositioning and removing components, more securely and conveniently on a shaft than with keyways, setscrews and locknuts. When the shaft and hub needs to be separated from each other for repairs, etc., it can be simply done by loosening of bolts. It saves lots of time and energy, and it also can be reused. This is difficult with the age old keyway system; it requires lot of physical effort (like hammering, etc), and time to separate the shaft and the hub. It also avoids backlash that is sometimes encountered with keyed connections, and allow generous tolerances on shafts and hubs. Features and benefits include: superior performance against reversing; dynamic and impact loading; ease of installation, assembly and disassembly; capable of transmitting high torques and axial loads; precise positioning and adjustments; and wide variety of sizes and styles. Applications are for shaft mounted gear units, crane wheels, conveyor pulleys, mixer shafts, pump impellers, bucket wheels, wind mill propellers, drum connections for belt conveyors, sprockets, ship and aircraft propellers, turbine rotors, cold forming presses, etc.
