Educational outfit with axial shell assembled by bearing

Abstract

The invention relates to an educational outfit with an axial shell assembled by a bearing, comprising a set of tapered bearings which can separate from each other with an inner ring and an outer ring mutually rotating, a bearing which can keep the two rings of roller separated from each other, a first bracket which has a dent part with an outer ring inserted in, a shell which has a bottom board forming a flat surface and a top board, with an opening bigger than the external diameter of the outer ring, of an upper end face parallel to the flat surface, a second bracket which has a flange fastened on the upper end face of the top board and a dent part formed inside for keeping the bearing upright between the bottom board and the top board and forming a clearance between the bottom of the dent part and the end face of the outer ring on the bearing, a first measuring apparatus which can measure the height size between the upper end face of the top board and the end face of the outer ring, and a plurality of gaskets which has different thickness corresponding to the clearance between the bottom of the dent part of the second bracket and the end face of the outer ring.

Description

technical field [0001] The present invention relates to an educational tool for teaching an operator the technique required for assembling an axial housing via a bearing. Background technique [0002] As a mechanism that forms a complex and compact power transmission system by assembling a plurality of axial housings via bearings, there is, for example, an automatic transmission of a vehicle (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. H10-246310 [0004] Since the automatic transmission has restrictions on being mounted on a vehicle, various components can be accommodated without gaps in a limited space. However, considering component deviations, etc., looseness (gap) will inevitably occur after assembly. Especially in the case of assembling a shaft via a bearing, the inner ring and the outer ring can move relative to each other with a certain degree of freedom via balls or rollers, so clearance is like...

AI Technical Summary

Problems solved by technology

[0005] In the case of looseness after assembly, the conventional method is to adjust the gap by using a shim selected according to the looseness. However, such adjustments are usually not numerically converted into a certain value, and largely depend on the operator's Assembly experience

[0006] However, in the case of learning gap adjustment using an existing product, for example, in the case of using an automatic transmission, as described above, since assembly is performed under a complicated and dense layout, it is not limited to learning for the purpose of gap adjustment. Clearance adjustment must also be disassembled and assembled around it

In addition, when the size and weight of existing items are large, such as automatic transmissions, it is difficult to carry out learning tasks

[0007] Moreover, it is also disadvantageous in terms of cost when using expensive existing items such as automatic transmissions for learning.

In addition, when existing items such as automatic transmissions are large in size and weight and expensive, it is difficult to prepare a large number of them, and there is a problem that the number of people who can learn at one time is limited.
