4 INITUR PRISION TORQU SPINS TURS N NITS The Helix inear Precision Torque T Splines are a convenient and efficient device that allows low friction motion while transmitting torque. In a Helix PT Spline assembly the high strength composite polymer bushing carries the load between the rotating member (inner race) and the rotating/translating member (bushing). Helix PT Splines are coated with Helix H4X PT coating for long life and anti-friction. The PT bushings are offered in a standard freewheeling design and an anti-backlash design. These bushings can be mounted using an integral thread or they can be assembled using a round or compact mounting flange shown on page 7. The Helix PT Splines and ushings can be modified to custom designs and configurations. ontact Helix Sales ngineers at sales@. Helix inear will provide customer specific part numbers on request - your drawings to sales@ SPIN TRS QUIVNT ITR The equivalent diameter is the average diameter between the root diameter and the shaft diameter. SHT ITR - The shaft diameter is the outside diameter of the inner race. ROOT ITR - The root diameter is the diameter of the inner race measured at the bottom of the groove. This is the diameter used for determining column strength, critical speed and machining dimensions. SPIN TTH - The grooves in the inner race that mate with the outer race are referred to as the spline teeth. The number of teeth varies with the diameter of the spline shaft. (See below) Spline Shaft iameter Number of Teeth (6.35mm) (9.52mm) (12.7mm) 18 STRIHTNSS - lthough Precision Torque T Splines are manufactured from straight, cylindrical material, internal stresses may cause the material to bend. When ordering random lengths or cut material without end machining, straightening is recommended. Handling or machining of splines can also cause the material to bend. efore, during and after machining, additional straightening may be required. When ordering splines with machined ends from Helix inear, the following straightness tolerances can be expected: Precision Torq T Splines are straight within.003 in per foot when shipped from the factory, and do not exceed.030 inch in any 6 foot section. XIU TWIST - Precision Torque T Splines will have a maximum twist of 3 /ft about the Spline Shaft axis. ROTTION SH - acklash or lash is the relative rotational movement of an outer race with no rotation of the inner race (or vice versa). Rotational backlash for the Precision Torque T Splines with standard bushing is limited to a range of.005 to.009 at the equivalent diameter. TPRTUR Precision Torque T Splines will operate between -65 and 200 with proper lubrication. N HININ - To obtain optimum performance of your spline assembly, it is recommended that the machining be performed at the Helix inear factory. Splines may be purchased machined to your specifications. N IXITY - nd fixity refers to the method by which the ends of the spline are supported. RITI SP - The speed that excites the natural frequency of the spline inner race is referred to as the critical speed. Resonance at the natural frequency of the inner race will occur regardless of orientation (vertical, horizontal, etc.). The critical speed will vary with the diameter, unsupported length, end fixity and rpm. Since critical speed can also be affected by shaft straightness and assembly alignment, it is recommended that the maximum speed be limited to 80% of the calculated valve. The formula used to calculate critical speed is found on page 220. The critical speed chart can also be used to quickly determine the minimum diameter ommerce Park Road eachwood, OH US or sales@

5 PT - Specifications O INITIONS OVRTURNIN O - load that rotates the outer race around the longitudinal axis of the inner race. (See below) TORQU O - load that rotates around the radial axis of the inner race/spine. (See below) OVRTURNIN O TORQU O SI O - load that is applied radially to the outer race. (See below) TRI SPIITIONS SI O Precision Torque T inner races are made of high quality 304 stainless steel and coated with H4X PT coating. Precision Torque T bushings are made of high strength bronze and Helix brand high-load composite polymer. PRO - Preload is a load introduced between bushing and spline that eliminates radial movement. Preloaded assemblies provide zero backlash for excellent repeatability and increased system stiffness.
