I am looking at a comparison between the impact properties of wood and plastic. However, wood impact properties are given in reference to a different test. Plastics use I-zod or charpy. Is there data on how wood would perfrom in these tests. Even a simple comparison such as "pine has an...
Does a worm gear have to be helical? Or can it be a spur gear?
My output shaft angle is 58 degrees instead of the common 90 degrees. I have read from several sources to treat this as a crossed axis helical gear configuration. Crossed axis helical gears with opposite hands, require that...
Does anyone know where I could find information regarding the nubmer of seats for each of the FEA packages?
e.g. 10,000 seats ansys, 7,000 abaqus, 9,000 Femap, etc.
I am looking for a shaft and bushing combination. THe shaft will have a medium load, low rpm, at normal temp, and occasional use. THe bushing will not be lubricated. I would like to use brass or bronze.
I am curious about the surface roughness specs for the shaft and bearings as well as the...
I have a skewed worm assembly for medium power transmission and indoor use. I have choosen 1045 steel for the helical worm gear and will probably use 1045 for the worm as well. However I have seen similar gear setups with a gold or bronze coating on the steel. I presume this is for friction...
I am looking for reference information on skewed worm gears. All of the info I have found is related to a 90 degree angle between the non-intersecting shafts. I am looking at designing a worm and worm gear assembly where the shafts are skewed at 30 degrees.
Thanks
