Description
Technical field
The present invention relates to a kind of thin-walled roller bearing technical equipment field, particularly to a kind of thin-walled crossed roller bearing dress
Allotment of labor's skill.
Background technology
Precise thin-wall crossed roller bearing substantially divides two kinds: outer ring is split type and Internal and external cycle monoblock type, and Internal and external cycle entirety is thin
Wall crossed roller bearing generally offers a pilot hole in the middle of the outer diameter face of outer ring, is used for loading roller, and at roller pilot hole
Middle tight fit arranges assembling cylinder, the through hole of horizontally set one 1 millimeter on assembling cylinder, and is being inserted into location by hole
Straight pin, is positioned assembling cylinder by alignment pin.
In prior art, the assembling shortcoming existed or deficiency are: 1. assembling cylinder cannot precisely resetting, cause greatly
Width improves processing technique precision, thus increases equipment and manufacturing cost；2. poor due to assembling repetitive positioning accuracy, cause roller to exist
In raceway, operating has some setbacks；3. during processing, having some setbacks because roller operates in raceway, the fraction defective caused improves；Although 4. dress
Join cylinder molding together with raceway, but when roller assembles, will first take out assembling cylinder, to be installed complete roller after, then will dress
Join cylinder again to playback, the axial error between V-groove and V-type rolling channel below assembling cylinder and radial error, it is impossible to location
It is difficult to precisely so that roller has some setbacks when operating in raceway groove, affects the life-span in life-span of properties of product and product.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of thin-walled crossed roller bearing assembly technology, for existing
Deficiency in technology, uses wall thickness close to arranging the solid box inner ring of the limit, bearing outer ring, the assembling on bearing outer ring
