Help: Bevel Gear Mounted On CIM Shaft?

[854 bears]

I am doing a little off season project and experimenting with different ways to mount the drive motors to save space. My current design involves a set of spiral bevel gears, with one mounted directly onto the CIM shaft and the other on an axle supported on both ends. I don't have any experience using or mounting bevel gears, but during my research one source said that these type of gears puts a strong horizontal force on the shafts. All I am wondering is weather or not the CIM will be able to handle this force, or if I need to support the other end of its drive shaft. I don't have many specifics yet, but the gears will most likely be a 3:1 reduction.

PS. these plates will be CNC'd so everything will be precisely aligned, and built strong.

Any suggestions or thoughts will be greatly appreciated.

Thanks,
