mounting grooved shaft with oblique bearings

[Zigtrust]

hello to all I am a student in mechanical ing and I would like to have opinions on the interpretation of an explosion and practical procedures for mounting all components.
I have attached the explosive and my draft representation that I hope is clear regardless of all the dimensions taken randomly and the norms of representation not respected.
some questions:
a-the mounting of the left bearing directly on the conical wheel is reasonable? I chose this possibility considering the installation procedure proposed later.
b-is common practice to mount two different size bearings on the same tree, possibly there are contraindications?
c-not having practical sensitivity in assembly I would fully foresee the following operations:
1_assembly ring and bearing on conical wheel
2_left spacer and conical wheel on shaft with locking by means of a needle
3_assembly right bearing in tubular support seat
4-shaft insert in the tubular support from left to right (preventing the relative slide of the right bearing rings)
5-space spacer and cylindrical wheel
6_precarious of oblique bearings via right-hand needle
thanks in advance to those who want to have a comparison.

Technically, with adequate tolerances, it is possible.

b-is common practice to mount two different size bearings on the same tree, possibly there are contraindications?

where there is the need is admitted.

c-not having practical sensitivity in assembly I would fully foresee the following operations:
1_assembly ring and bearing on conical wheel

the spacer (ring) and the internal ralla bearing on the conical crown.

2_left spacer and conical wheel on shaft with locking by means of a needle

ok spacer and conical wheel on the tree. the conical wheel would not block it with a wreath but with a nut and washer if you use the threaded pin as in the drawing, with a screw you or tcei and washer if you run a hole in the head of the shaft.

3_assembly right bearing in tubular support seat

mounting outdoor rake right bearing in the seat of the support.

4-shaft insert in the tubular support from left to right (preventing the relative slide of the right bearing rings)

before this operation you have to mount the left bearing outer ring in the support seat.
then insert the ball wreath and carry out the operation described by you, but you don't have to worry about sliding the right bearing rings because you have only mounted the outer ring on the support (phase 3).

5-space spacer and cylindrical wheel

Inserting crown of balls on the outer ring of the right bearing, then next calettamento inner ralla, spacer and cylindrical wheel.

6_precarious of oblique bearings via right-hand needle

Okay.

other considerations.
This is a hand-made sketch and off-scale I do not rely on some insights that I presume have already been adopted in the drawings and in the final overall.
I do not know if your design also includes the part with conical gear coupled with that of your sketch; in case of affirmative it is necessary to predict for that gear the possibility to adjust the game of ingration through thickness.

Thank you very much for the exhaustive answer.

This passage in particular opened a world to me, I was convinced the bearings should always be assembled already and instead I was wrong of big.

with thickness you mean the possibility to insert appropriate spacers to adjust the position of the other conical along the axis of the tree on which it is calettata?

In fact, if you consult a catalog of a bearing manufacturer you will notice that the same applies to conical roller bearings and certain types of cylindrical roller bearings.

Yes, exactly.
