NAB model Air shaft brake is an ecnomic brake
Following are the characters of this pneumatic shaft clutch:
1) NAB model (standard) air shaft brake, installed conical shaft spanned tube with peg onto shaft, friction lining can be replaced without changing anything of the mechanical equipment. It reduced heat generated from friction by cooling plate mounted on disc with hub. Torque is from 53-636N.m.
2) Friction lining is two-cut style, using screwdriver to take out head inside screw through hole of disc with hub, in order to replace friction plate.
3) Stop stable
Stop stable by adjusting air pressure.
4) Suitable for quite frequent sliding movement and high frequency usage
Perfect heat dissipation, it can be used in high frequency, high load, and sliding movement. Besides, it can be used in idle.
5) Wide adjustable range of torque
It can adjust torque in wide range according to air pressure adjustment.
6) Long service life and easy replacement of friction plate
Thicker friction plate, little abrasion and long use life. And when replace, it works without changing anything of the mechanical equipment.
NAB model air shaft brake is a standard friction plate brake, it is driven by air pressure. It can replace HAC HDB model friction disc brake fully with same specification.
Installation Instruction
1. Mounted onto shaft
NAB model brake installs conical shaft spanned tube onto shaft in following order:
1) Embed the key into shaft inside, and get brake body through shaft.
2) Find the key, and install conical shaft spanned tube into where the key is embedded.
3) Align the cut-out of conical shaft spanned tube to the bolt hole of shaft spanned disc and use three screws to fasten them. When fasten, pay attention to see the dial indicator, and the level deviation of fitting surface of pistol. Try to reduce the deviation to its minimum level and fasten interlaced.
2.Installation onto machine table
Supported by the brake torque, fix flange portion by 4 screw bolts, put torque bolt into cut-in of brake body to prevent turning.
The squareness between cover and shaft to install flange must be controlled under 0.05mm.
Note:In order not to produce load to brake axis, install the conical shaft spanned tube onto shaft before making sure that there is no clearance between machine table.
