1. Overview of ZQA series cylindrical gear reducer
ZQA type reducer has improved and designed on the basis of ZQ tyoe,in order to enhance the load capacity and replace the old ZQ type.There are no change at contour,shaft end and installing size,but change materials of gear as following:the material of gear shaft is 42CrMo,big gear is ZG35CrMO,and the hardness of gear shaft is 291~323HB,big gear is 255~286HB.
1. Type
Symbol sample
ZQ improved reducer's total center distance 500mm,nominal transmission ratio is 25,the third assembling
form,solid shaft extension,can marked:ZQA500-25--Z.
2. Transmission ratio
Actual transmission ratios of ZQA type are same except is=23.34(Because the deviation is less than 4% between
ZQ type's autual transmission ratio and nominal's),see table
3. Contour,shaft end and installing dimensions
The Contour,shaft end and installing dimensions of ZQA type are same to ZQ type
4. Load capacity
Get alloweld input power and duty M5 of output torgue of ZQA type 9 reducer intable,including continuous type 10.
Get max allowable radial load of ZQA type reducer in table.
