Item Code: N7015.1
Our clients can avail from us premium quality Keyless Transmission Element (N7015.1) supports which are manufactured using quality material.
Features:
Very high transmissible torque. Wide double self releasing taper design for enhanced bending moment capacity. Fixed axial hub position during assembly. No demand of high quality surface finish of shaft & hub. Easy installation & removal. Overload protection effect but not advised to use as slipping device. A frictional locking connection, have no play. Due to centering wed (guide) & relatively large (taper) guides, locking assembly center according to shaft / hub manufacturing accuracy.
since torque (force) is transmitted by contact pressure & friction betweencontact surfaces; condition of contact surfaces and proper tightening of screws is great importance.
Installation:
Locking assemblies are supplied ready for installation. Before installing shaft and bore contact area(s), screw threads, are to be clean and slightly oiled. Loosen all screws by minimum 2 turns and transfer some [2 to 4] screws in to push off threads in front thrust nut [2] and middle ring[3], in order to disengage tapers for easy installation. After insertion of assembly on to shaft & into hub, relocate locking screws used for releasing assembly. Hand tighten screws slightly and adjust assembly as required. Use torque wrench and set it approximately 5% higher than specified tightening torque (ma). Tighten screws (f) in diametrically opposite sequence, using only 1/4 turns for several passes, til no screw turn more. Since tightening of a screw will always relax adjacent screws, apply over torque for 1 to 2 more passes to compensate for a system-related relaxation of locking screws. Reset torque wrench to specified torque and check all locking screws. No screw should turn at this point, otherwise repeat step(f) for one or more time.
Note: The transmission torque & axial force are in fact directly proportional to the sum of of the pull of thetightening screws and as a consequence, the tightening torque of screw i. E. Ma of screw.
