Check and adjustment of the preload of the bearing of the mixer The adjustment of the bearing preload is very important during assembly and must have a certain preload. Adjusting the pre-tightness of the gear bearing will also affect the engagement marks of the master and slave bevel gears. First, adjust the appropriate bearing pre-tightness, and then adjust the engagement clearance or engage the impression. As an important form of Centrifugal Pump, double suction pump is widely used in engineering because of its high lift and large flow. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

The simplest method of inspection is a rule of thumb. Turn the main and driven bevel gears by hand and you should be able to turn freely, pushing the gapless feel in the axial direction.
Another method is measurement: Pull the master and slave bevel gear check with a torque wrench or spring balance.
