Shaft and Bearing
NO1  Shaft

The shaft of Shrpe Mixers is made of monolithic alloy.Mixer shafts are required to transmit the power from the mixer drive to the impeller(s). With the transmission of this power, the shaft must handle the loads occurring including the transmission of torque, overhung moment due to hydraulic forces, and thrust. The shaft must also be designed to be stiff enough to limit vibration and deflection to acceptable levels. Mixer shafts are commonly built from solid round bar, hollow shafting, or a combination of both.
The strength of a shaft is determined by the section modulus of the shaft. For a given section modulus, a hollow shaft will be larger in outside diameter, but will weigh less than the equivalent solid shaft.
 Solid shafting has been the most common choice among mixer manufacturers for many years because of availability, ease of construction and the fact that many impeller hubs require a key to transmit torque. Many mixer manufacturers stock one-piece impeller hub castings to which they bolt blades. These hubs slide onto the shaft from one end and are held in place with a key and set-screw. Since the required mating keyway would cut through a hollow shaft, a solid shaft is required. This design and the required inventory is a commitment to solid shafting by default. The disadvantage of keyed one-piece hubs is that they can be difficult to remove from the shaft, steady bearings must be disassembled to allow clearance for impeller removal, and the impeller will usually weigh more due to the required thickness at the bolted blade attachment area


NO2  Bearing



Shrpe Mixers bearings are special flanged bearing components customized by Dodge and Timken Bearing Company. Tapered roller bearings are used to support both radial and axial loads. Double-row tapered roller bearings can bear bidirectional axial loads.
This is more convenient for parts replacement and maintenance costs.。
