The main landing gear trunnion fitting failures occurred within 0.25 seconds of each other. |
|
The trunnion nut is linked to and actuates the rudder tab by a lever and rod assembly. |
|
The upper trunnion pivot points were attached to the landing gear wing box structure, which had torn free from its surrounding structure. |
|
Support plates under each trunnion are used for setting the ladles onto stands or ladle cars. |
|
A visual inspection of the fractured surfaces identified several visible features on the fractured strut housing trunnion arm. |
|
Examination of the main-rotor mast and the head trunnion indicated that the damage was caused by a vertical movement of the hub. |
|
The fracture location was below the trunnion drive splines just below the split cone support groove. |
|
The top end of the rod is threaded and rotates in a trunnion nut that moves up or down, depending on which direction the trim wheel is rotated. |
|
The trunnion nut on the rudder tab actuating rod was found one turn from the upper limit of travel. |
|
Most shops have three converter shells and one trunnion ring at a blowing station, rotating them between operation, relining, and preheating. |
|
The trunnion nut was found one turn from the upper limit of travel, positioning the rudder tab to the left. |
|
Aeromil used the adhesive during the bushing installation into the trunnion arm on the nose gear assembly. |
|
Both main landing gear trunnion fittings failed and the landing gear collapsed. |
|
With the rudder tab in the neutral position, the trunnion nut is positioned approximately midway on the threaded rod end. |
|
The nose landing gear failure was caused by the fracture of the oleo strut housing trunnion link arm, which was initiated by an existing fatigue crack in the bore of the link arm. |
|
The shells are built of heavy steel plates and sit in a trunnion ring so that the converter may be rotated for charging, testing, tapping, and slag-off. |
|
The towers are separated by six arciform gates, convex to the Mississippi, and hinged in trunnion blocks secured with steel to carom the force of the river into the core of the structure. |
|
The damage was considered as secondary to the trunnion link failure. |
|
Heavy-duty cast-iron yoke-style trunnion assembly ensures complete vibration dampening, mounts separately to cabinet for easy alignment of blade to miter slot. |
|
The trunnion drive splines were torsionally displaced one half of a spline from the split-cone support splines in a clockwise direction as viewed from above. |
|
|
Full cast-iron table with dual trunnion tilting mechanism. |
|
We turned a standard VMC into a trunnioned machine and now, in the average week, we run 100 jobs through the trunnion. |
|
The design includes internal trunnion blocks which eliminate the need for the lower ball trunnion to penetrate the body cavity, www. |
|
It was now time to install the barrel in the trunnion and set headspace. |
|
Further, inspection of the mills bearings during downtime has revealed noticeable deterioration and issues with the ball mill trunnion bearings and lube system. |
