Lubrication wedge
Characteristics:
The lubrication wedge is very simple less expensive but less effective alternative of lubrication of the open geared transmissions. The lubricant is transported to the lubrication wedge placed close to the tip cylinder of the pinion. Inside the lubrication wedge, which is as wide as the pinion and its surface adjacent to the pinion is worked to the cylinder shape with radius corresponding to the radius of the head circle of the lubricated pinion, there are channels, through which is the lubricant transported to several places all over its width. The lubricant outlet from the lubrication wedge is wiped by head edges of the pinion teeth and consequently spread over the active surface of the teeth side by the stroke of pinions tooth with driven ring.
Description:
The source of the pressure lubricant is the electric piston pump (a), which is connected directly or through the progressive dividers to the lubrication wedge (b). 
Function:
If the pump runs, the forced lubricant is transported to the lubrication wedge placed close to the tip cylinder of the pinion. The lubricant outlet from the lubrication wedge is wiped by head edges of the pinion teeth and consequently spread over the active surface of the teeth side by the stroke of pinions tooth with driven ring.
Standard elements for lubrication wedges:
a - Pumps
b – Lubrication wedge
Additional parts of the system:
- progressive dividers
- Lubricant distribution (tubes, hoses, screw-coupling, anchoring and assembly material)
Main fields of usage:
Less exacting and less loaded gearings with smaller dimensions and with intermittent occasional operation.
