Abstract
The utility model discloses a kind of protection structure of motorcycle engine gear-shift shaft; including setting the gear-shift shaft on engine, feature is also to include offering installation through-hole on gear-shift shaft counter-jib, gear-shift shaft counter-jib; bearing assembly is provided with installation through-hole, gear-shift shaft is located in bearing assembly；Advantage is directly assembled in the case where former engine fittings are not dismantled, and installs very easy, its function effectively protects gear-shift shaft flexural deformation; inside more rotates flexible using needle bearing link; shift is relatively sharp, service life of aeroengine extension, reduces and uses and after cost.
Description
Technical field
The utility model is related to a kind of motorcycle engine gear-shift shaft, more particularly to a kind of motorcycle engine gear-shift shaft
Protection structure.
Background technology
Existing horizontal four-stroke engine at present, due to the limitation of profile size, gear-shift shaft can extend lengthening, actually make
Gear-shift shaft bending can be caused during, while casing oil sealing easily weares and teares, causes engine oil leakage to cause damage, increases
Use cost and after cost.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of protection structure of motorcycle engine gear-shift shaft, protects
Shield gear-shift shaft is not susceptible to bending.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of motorcycle engine gear-shift shaft
Protection structure, including the gear-shift shaft on engine is set, it is characterised in that：Also include gear-shift shaft counter-jib, described gear-shift shaft
Offered on counter-jib and bearing assembly is provided with installation through-hole, described installation through-hole, described gear-shift shaft is located in described
Bearing assembly in.
Further preferred scheme of the present utility model is：Described bearing assembly includes bearing and spacer, described bearing
Outer ring be fixedly connected with the inwall of described installation through-hole, the inner ring of described bearing is fixedly connected with described spacer, institute
The gear-shift shaft stated is located in described spacer, rotates flexible using bearing link, shift is relatively sharp.
Further preferred scheme of the present utility model is：The end of described installation through-hole is provided with oil sealing, prevents bearing
Oil seepage on component.
Further preferred scheme of the present utility model is：Foot-operated end face is provided with described gear-shift shaft counter-jib, is used
When facilitate people to trample.
Further preferred scheme of the present utility model is：Counter-jib mounting seat, described gear-shift shaft are provided with engine
Counter-jib, which is bolted, to be arranged in described counter-jib mounting seat, and structure is more consolidated.
Compared with prior art, the utility model has the advantage of not dismantled in former engine fittings in the case of directly
Assembling, installs very easy, and its function effectively protects gear-shift shaft flexural deformation, and inside more rotates spirit using needle bearing link
Living, shift is relatively sharp, service life of aeroengine extension, reduces and uses and after cost.
