Description
Technical field
The present invention relates to crankshaft box of motorcycle engine to assemble field, is driven in particular to a kind of CG engine crankcases
Gear alignment measurement accessory.
Background technology
CG engines be it is a be exclusively used in motorcycle by cam engagement push rod realize valve open or close start
Machine, therefore also known as rod engine.In CG engines, bent axle and camshaft are arranged at intervals side by side, and crankshaft end socket is provided with just
When driving gear, be rotatably engaged a cam on camshaft fixed setting and camshaft, the outer one end of cam, which is arranged, to be fixed with
The timing driven gear wheel being meshed with timing driving gear, cam connect push rod by lower shake-changing arm, and push rod is connected by upper rocker arm
The power of bent axle is simultaneously delivered to valve by valve, and then drives valve motion, makes it follow being rotatably assorted for bent axle to realize valve
Opening and closing, realize engine continuous doing work.
Traditional CG Engine Series crankcase is made up of left and right two parts casing, and right case is individually processed.Add
1 machining crankshaft bearing borehole is respectively disposed with man-hour right case, and two mounting holes of camshaft are arranged on left box body.Because adding
Form and position tolerance during work be present, the centre-to-centre spacing of bent axle and camshaft hole changes greatly after engine mould assembling.To ensure suitably just
When running clearance can better ensure that the cooperation between timing driving gear and timing driven gear wheel, during CG engine assemblies,
A corresponding timing driving gear, which devises multiple groups, has the timing driven gear wheel of different distance over bar., first will just during assembling
When driving gear be fitted on bent axle, reselection matching timing driven gear wheel install and complete gear coordinates.During general assembling,
It is manually by virtue of experience to carry out with the mode of feel matching somebody with somebody tooth.It is manually poor with tooth stability, it is not easy to ensure sideshake, because of gear backlash
Timing Abnormal Sound Trouble rate is high caused by improper.
Applicant once applied for the CG engine crankcase transmission systems that a kind of number of patent application is 201410434212.0
Assembly method, this method finally installs timing driven gear wheel and to complete timing driven during the transmission system is installed
Cooperation between gear and timing driving gear, during timing driven gear wheel is installed, first measurement obtains timing driven gear wheel
The centre-to-centre spacing alignment error between timing driving gear, then choose the timing driven gear for the tolerance that matches with centre-to-centre spacing alignment error
Wheel engages installation with timing driving gear.So, CG engines timing gears in use can be solved to a certain extent
Caused abnormal sound or the problem of utter long and high-pitched sounds, improves the service life of CG engines.
But the principle of the patented technology is the detection means using mechanical structure, by axiality ring gauge and axiality feeler gauge
By physical object to be detected（That is bent axle outer surface and cam shaft mounting hole inner surface）It is transferred to convenient detection outside crankcase
Position, then detected again using clearance gauge, the gear for then choosing matching is installed.This mode is still using people
Work operates, and carries out mechanical measurement by personal, still easily produces error, while this measured object is leaned on into ring gauge and feeler gauge
Carry out the mode that measures after transferring position, also due to the presence of ring gauge and feeler gauge itself error and increase tested numerical value and miss
Difference, cause final gear pairing result inaccurate, it is difficult to it is different to eliminate accurately and effectively the improper caused timing of gear backlash
Ring.Complex operation also be present, the defects of causing efficiency of assembling low using ring gauge, feeler gauge and clearance gauge operation by worker simultaneously.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved by the invention are：How a kind of detection behaviour is provided
It is more convenient, automaticity is higher, and detection error is smaller, as a result more accurate reliable CG engine crankcases travelling gear dress
With measurement accessory, it is used for the auxiliary assembling of CG driving engines gear, it is improper can more efficiently to eliminate gear backlash
Caused timing abnormal sound, efficiency of assembling is improved, improve engine qualification rate, extend engine life.
In order to solve the above-mentioned technical problem, present invention employs following technical scheme：
A kind of CG engine crankcases travelling gear alignment measurement accessory, it is characterised in that including crankshaft cam axis center
