The process of selecting small inch size drive components for new prototypes or production applications just became easier.
Fasteners get to grip with hubs
Fastening rotating components to shafts has become easier with the publication of the new 96-page "Handbook of Fairloc components, the integral fastener".
Three sizes of speed reducers are offered with ball bearing mounted input shafts allowing up to 6000rev/min input speeds.
The worm gears are made of phosphor bronze and the worms of hardened steel.
The three speed reducer types are offered with standard reduction ratios from 6:1 to 100:1.
The housings are made of aluminium alloy with a black anodised finish.
The inch units, identified as the A 2Z17, A 2Z18 and A 2Z19 Series, feature a breakaway torque of from 0.5 to 7.9mNm and an output torque of 0.5 to 4.4Nm.
Their maximum backlash is 0.5 degree and their maximum input speed is 6000rev/min.
Sintered bearings are used on all output shafts for all units.
These small drives measure from 1.25 x 0.75 x 1.53in.
The smallest unit features a 0.125in-diameter input shaft and a 0.375in-diameter output shaft, both 0.75in long.
The metric units, identified as the A 2Z17M, A 2Z18M and A 2Z19M Series, features a breakaway torque from 0.5 to 8mNm and an output torque of 0.51 to 4.41Nm.
The smallest drive measures from 31.8 x 19 x 39mm.
The smallest unit features a 3mm input shaft and a 4mm output shaft both 19mm long.
Requests for any special mounting requirements, ball bearings or different shaft diameters or other modifications are welcomed.
Prices, in single unit quantities, start at $207.39 for the 8:1 ratio speed reducer unit.
Additional specifications for the A 2Z17, A 2Z18 and A 2Z19 Series of speed reducers are contained in Catalogue D790 (Inch) and Catalogue D785 (Metric) both available free on request from Stock Drive Products.
