Precautions for product characteristics
(1) This product is an assembly dedicated gauge for ZST / ZSTD / SRHEF helical racks.
Precautions for assembly
(1) The ZST / ZSTD gear grinder rack is designed so that the backlash in the table will be made if it is assembled within the assembly distance (tolerance H7 to H8) of the ZSTP mating pinion dimension table. Please assemble to make the assembly distance always constant.
(2) ZST / ZSTD gear grinder rack has a finished pitch of -0.05 to -0.4 mm at the flange. When using by connecting, if you assemble the flanges in close contact each other, the pitch of the connecting part will become smaller and it may cause troubles. So please see "how to connect racks" shown above for assembling correctly.
(3) ZST / ZSTD gear grinder rack is a high-precision product with grinding on the mounting surface. If the accuracy of the base surface on which the rack is mounted is poor, the product performance will be affected. Therefore, please refer to the figure below for setting it on the mounting base surface with high accuracy of flatness and perpendicularity (recommended within 10 µm). Also, if the rack is not sufficiently mounted on the mounting base surface, the rack may move during startup and cause unexpected troubles. Please use the dowel together so that the load is not applied as much as possible in the shear direction of the mounting screw.
