Northern Lesson 3: Gear Pump Components Pump Unit Assembly Northern Pump is a full service gear pump manufacturer. We frequently build and assemble pump unit assemblies, or “Skids” as they are sometimes called. They typically consist of a Northern Heavy Duty Gear Pump, Electric motor, Shaft Coupling, and Coupling Guard, mounted on a Unit Base. We configure the mounting holes to match the application and install lifting hooks to safely move the unit. Electric Motor Shaft Coupling Northern Heavy Duty Gear Pump Coupling Guard Unit Base

form a gear set or a gear train . In a gear set, the input gear is called _ gear. The output gear is called the _ gear. Note: An idler gear or intermediate gear changes direction of rotation without change in gear set speed or torque Spinner &
tions under different speeds of a helical gear oil pump, herringbone gear oil pump and dislocation gear oil pump can be described as follows: (1) The flow pulsations reduce significantly at the low and medium speed within 1100 2700 rpm. Espe-cially the dislocation gear oil pump reduced greatly, 27% in 1100 rpm and 35% in 2700 rpm. 370 Wen Wang .
The next type of gear, and the most advanced gear discussed in this report, is the spiral bevel gear. This gear has the angled face of a bevel gear and also has angled teeth similar to those of a helical gear. The angle of the teeth varies along the face of the gear, which creates a curved tooth shape.
