MOUNING Wormshaft : housing and bearing design should allow an axial shifting, necessary for backlash adjustment. he total adjustment range is obtained with a permissible displacement equal to W, as per page 14. It is recommended, whenever possible, to use our backlash adjustment device, which is delivered preset (see page 15). he front ball bearing (see page 15) must be engaged on the shaft after the complete gear assembly, and before the backlash adjustment operation. Wheel ring : Arrows shown on wormshaft and wheel ring must be lined up during assembly (see page 14). As the bore A tolerance is 6, it is recommended to grind the shaft with a tolerance k5. his will eliminate any runnout between the wheel ring and the shaft. In order to facilitate the connection between the 2 parts, heat the wheel ring up to 50 C. After cooling, check that the wheel ring is no buckled, by applying a dial indicator on its face, while rotating the shaft. hen, finish the pins bores ((xy) S, see page 14) of the 2 assembled parts, as they are delivered pre-bored only. UBRICAION he best gear performances in terms of efficiency, life, temperature, will be achieved with a polyglycol lubricant such as MOBI GYGOYE 30 or equivalent. he ratings shown on page 5 can be considered only if this kind of heir performance are comparable to complete reducers, assuming following recommendations : Otherwise, screws can be also used. It is recommended to use tapper roller bearings on output shaft, in order to allow an axial displacement of the wheel, during the mounting operations, to center the gear correctly. he contact pattern can be checked with Prussian blue or any similar product. A good pattern should be located slightly on the right side of the wheel tooth flanks (on both sides). It is normal to have no contact on the left side of the flanks. his gap is necessary for a good oil film forming. See sketch below. DIRECION O ROAION lubricant is used. Before use, check that the inner paint of the housing is compatible (Epoxy paints can be used). Otherwise, use MOBI SC 634 or equivalent. 12 Output torsional backlash Size 1 arcminute 5 arcminutes MEDIUM 10 arcminutes BASIC BACKAS ADJUSMEN he accuracy of our servo DYNASE gearsets allows them to be set to less than 1 arcminute of backlash, without any efficiency or torque capacity losses (it is assumed than custom machined parts and mounting are correct). If our backlash adjustment device is used, simply remove some shims (delivered) between the bearing bush and the housing, until the desired backlash value is obtained. or high speed applications, a backlash between 0,5 to 1 arcminute is recommended. or very intermittent applications (rotary tables or milling heads of CNC machines for ex.), a backlash down to zero is tolerated, as soon as the no load input torque does not vary more than ± 30 % around the average value. 13
