Brunel torque limiting clutches type jcb




Clutches can be supplied pilot bored or finish bored and keywayed. The hub may be fitted to either and should be located against a shoulder to resist the resetting spring force and locked by means of set in the hub flange. Disengagement On overload, the balls are displaced axially through the housing, further compressing the springs.

Once out of their pockets, the balls roll on the face of the hub flange for one revolution before re-engaging and synchronizing the drive. Torque Adjustment The release torque is set by tightening nut 4 thus increasing the spring pressure.

Overview
Type JC clutches should always be used with a limit switch to bring the drive to rest within a few revolutions thus preventing possible damage by continual releasing and resetting. Brunel Safety Element Torque Limiters For The Water and Waste Water Treatment Industry Features & Advantages • Modular Ball Detent/Disc Spring Design • All Major Components 316 Stainless Steel • Three Safety Element Styles Available 1) Externally Adjustable 2) Disconnectable (Tamperproof) 3) Standard (Tamperproof) • All Wearing Surfaces D-2 Tool Steel through hardened to Rc62 min. • Complete Disengagement on Overload • Simple Manual Reset • Multiple “O” Seals • Adapts to All Drive Configurations • Large Torque & Bore Capacity Brunel Safety Element Torque Limiters have been protecting industrial power transmission systems around the world since 1971.

The Waste Water Safety Element “SE” Series Torque Limiters are designed specifically for the outdoor, corrosive “waste water” environment. They are made of 316 stainless steel throughout with the exception of D-2 ( Rc 62) tool steel “ working parts” in the safety element, “O” ring seals and PTFE bearings. The internal parts are packed with grease and are externally regreaseable.

Eight “O” seals prevent contaminants from entering the unit while a grease vent allows added grease to escape. Modular construction provides design flexibility and simple maintainability. Safety elements are precision Belleville spring loaded, single ball detent design.

A unique over center mechanism ensures complete and bidirectional disengagement on overload and simple, fast manual re-engagement. Three types of Safety Elements: standard, disconnectable, and externally adjustable are available and are interchangeable on the base unit. Safety Element Torque Limiters completely disengage on overload thus preventing damage and down time to the equipment.

When applied on reducer output shafts in rectangular settling tank drive systems, the “SE” Torque Limiter protects the reducer, drive chain, drag chain and flight bars. They can also be applied on conveyor drives or other sludge collection systems that have potential for jamming. Brunel Safety Element Torque Limiters For Extruder Applications Externally Adjustable / Disconnectable Module *(EAD) Features & Benefits • Modular Design Simplifies Maintenance User can replace Safety Elements (the working components) without removing clutch from shaft Clutch can be removed (dropped out) without moving motor back • Module Designs Available Standard Internally Adjustable Modules Externally Adjustable Modules *(EA) Torque adjustment by micrometer graduations Tamper proof externally adjustable design Disconnectable Modules *(D) Disconnect motor for testing of motor function and torque limiter function Tamper proof internally adjusted design Externally Adjustable / Disconnectable Modules *(EAD) Incorporates both features above Brunel Safety Element Torque Limiters have been protecting industrial power transmission systems around the world since 1971.

The Extruder Safety Element “SE” Series Torque Limiters are designed specifically for the precision requirements of twin screw extruder applications. They are totally enclosed and made exclusively of steel (except coupling flex elements & seals). The wearing parts in the Safety Element Modules are D-2 tool steel thru hardened to Rc 62 minimum.
