Folks,
Here's a photo album of the splined shaft from my hydraulic pump. The interior splines of the mating PTO are identically worn.
I'm in the process of identifying the steel, but I believe it to be a high tensile steel (4140 or 4340). My apologies for not being able to narrow this down...
I have a hydraulic pump with a 7/8"-16/32DP straight involute external HT alloy steel spline shaft. The splines are experiencing contact fretting. (See spec's below and pic attached). The pump connects to internal splines of a constant mesh PTO, which in turn is bolted to a truck transmission...
Folks,
I'm having trouble interpreting a Modal Analysis I did on a bus chassis. This is for my own interest only - I'm somewhat a busnut.
I'm modeling a bus chassis from one of the major tour bus companies. It's 102" wide, 12.5 ft tall, and 45 ft in length. The chassis is a space frame. The...
Folks,
I'm trying to figure out what material my fan hub is made of so that I can know it's yield point. It is either cast or ductile iron.
The application is a hydraulic fan drive on a bus. The fan motor shaft is a 1:8 taper with a 5/8-18 UNF thread for the nut. The shaft can take a torque...
