Description
Technical field
The utility model relates to a kind of hob head, and specifically a kind of novel hob head be arranged on work top, belongs to machine tooling field.
Background technology
At present along with the economy of China develops rapidly, accession to the WTO, the equipment of China is subject to enormous impact, but under every unfavorable conditions, some facilities obtain significant progress, hob head is as one of part most important on gear-hobbing machine, vital effect is played in the use of gear-hobbing machine, but traditional hob head wearing and tearing are comparatively serious, conical surface gear wear intensity is large and install and change convenient not, and service life is short.Therefore, a kind of novel hob head be arranged on work top is devised for the problems referred to above.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of novel hob head be arranged on work top, has safe to use, practical, simple to operate, be easy to the advantages such as replacing and installation, by optimizing overall structure, meet different instructions for use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel hob head be arranged on work top, comprise fixator, rolling bearing, groove, conical surface gear, hob head rotating shaft, boss, rolling bearing inner ring, ball and rolling bearing outer shroud, described fixator is arranged on one end of hob head rotating shaft; The other end of described hob head rotating shaft is provided with conical surface gear; Described hob head rotating shaft is fixedly installed fluted and boss; Described hob head rotating shaft is provided with rolling bearing; Described rolling bearing is provided with rolling bearing inner ring and rolling bearing outer shroud; Ball is provided with between described rolling bearing inner ring and rolling bearing outer shroud; The mode that described rolling bearing adopts piecemeal to connect is fixed on hob head rotating shaft.
Further, described fixator adopts square structure and is provided with screw thread all over the body.
Further, described conical surface gear adopts boss fixed form.
Further, described rolling bearing inner ring is provided with boss.
Further, described conical surface gear adopts high-strength abrasion-proof metal to make.
The beneficial effects of the utility model are: the fixator of this kind of novel hob head be arranged on work top adopts square structure and the whole body is provided with screw thread, easier when being convenient to install and fix and dismantle; Described conical surface gear adopts boss fixed form, conical surface gear is changed because of the difference of wearing and tearing, improves the life-span of use; Described rolling bearing inner ring is provided with boss, is convenient to the fixing of rolling bearing; Described conical surface gear adopts high-strength abrasion-proof metal to make, and improve the life-span of use, and this kind of novel hob head be arranged on work top is safe to use, practical, simple to operate, is easy to change and install, and is applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2: a kind of novel hob head be arranged on work top, comprise fixator 1, rolling bearing 2, groove 3, conical surface gear 4, hob head rotating shaft 5, boss, rolling bearing inner ring 7, ball 8 and rolling bearing outer shroud 9, described fixator 1 is arranged on one end of hob head rotating shaft 5; The other end of described hob head rotating shaft 5 is provided with conical surface gear 4; Described hob head rotating shaft 5 is fixedly installed fluted 3 and boss 6; Described hob head rotating shaft 5 is provided with rolling bearing 2; Described rolling bearing 2 is provided with rolling bearing inner ring 7 and rolling bearing outer shroud 9; Ball 8 is provided with between described rolling bearing inner ring 7 and rolling bearing outer shroud 9; The mode that described rolling bearing 2 adopts piecemeal to connect is fixed on hob head rotating shaft 5.
As optimisation technique scheme of the present utility model: described fixator 1 adopts square structure and the whole body is provided with screw thread; Described conical surface gear 4 adopts boss 6 fixed form; Described rolling bearing inner ring 7 is provided with boss 6; Described conical surface gear 4 adopts high-strength abrasion-proof metal to make.
As production points for attention of the present utility model: conical surface gear adopts alloy carburizing steel to make and heat treatment in advance is normalizing, its objective is the abnormal tissue in order to change as-forged condition, obtaining suitable hardness in order to machining.Finished heat treatment is generally that quenching after carbunse adds lonneal.Make top layer obtain high-carbon tempered martensite and add carbide, case hardness is generally 58 ~ 64HRC; Core is organized, and depending on the quenching degree height of steel and the size of accessory size, can obtain low-carbon (LC) tempered martensite or other non-martensite microstructures, heart portion has good obdurability.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
