oddity Analysis Of Motorcycle Gear Damage
There are many kinds of motorcycle gear, such as master and driving gear, amend gear, begin gear, rear driving gear, balancing gear, timing gear, tachometer gear and fuel pump gear. Here is some analysis more or less some common gear damage, taking into consideration gear tooth direction wear, gear fatigue and gear tooth broken.
There are many kinds of motorcycle gear, such as master and driving gear, regulate gear, start gear, rear driving gear, balancing gear, timing gear, tachometer gear and fuel pump gear.
The behave of motorcycle gear is to transfer knack or fine-tune the speed.
But due to the alternative position, the energetic load is as a consequence different, such as shock, pulse, distortion and bending. Then, the study is different too. There are two types of the damage, one is gear noise and the other is gear damage.
Here is some analysis roughly some common gear damage, in the same way as gear tooth approach wear, gear fatigue and gear tooth broken.
- Gear tooth slant wear
Tooth tilt is wore to shine, tooth thickness become thinner, wear rim between full of zip point of view and non gate face, even worse, gear summit become pointy, diameter become smaller, and the entire tooth disappeared.
The specific reasons are:
- There are sand and dirt inside the lubricating oil. Especially in dusty areas, if the motorcycle engine sealing is not good, it easily does hurt to cheap brakes, which will wear and tear.
- The hard tooth aim is too severe and there will be large frictional resistance in imitation of meshing, the soft tooth point of view will be chipped and wear out soon.
- The viscosity of motorcycle lubricatingoil is low, after that the oil film will be not thick enough.
- The gear tooth slope is not difficult enough, or the extremity of hardened mass is too ample and can’t wear well.
- The gear tooth thickness is too huge or the middle distance is too small, which will cause the meshing clearance is too little to form the oil film and subsequently wear out.
Resolution:
- Make positive the sealing of the motorcycle engine lubrication system, tweak the seal gasket or apply seal paste after disassembling the gearbox to avoid dust. At the similar time, replace lubricating oil timely as required.
- Improve the truthfulness of tooth face, especially the hard tooth bearing in mind there are a large gap between a pair of hard and soft tooth, there must have low roughness.
- Use the oil gone high viscosity.
- Ensure the air of heat treatment, especially the severity of hardening bump and surface hardness.
- Control the thickness and the box center distance to ensure the machining quality,
Example:
- Fault. Riding a motorcycle after 5000 km, the odometer did not turn. contact the motorcyle gear, found that thepersonal watercraft parts or motorcycle sprocket have been wore out.
- Detection. Check the appearance. There is no lubricating oil inside the motorcycle gear bin and there is a lot of dust and further dirt upon the gear face. And there is no pain in the same way as tooth point roughness and lubricant viscosity. discharge duty the defective part, the tooth thickness has decreased significantly which indicate there is some misfortune on heat treatment of the motorcycle gear, but there is no pitting on the surface, that is to say, there is no fault following surface hardness, most likely the aberration happened for that hardness of enlargement intensity is not enough.
- Analysis. From the above test, there are two main cause of motorcycle gear wear. One is needy sealing of the gear box, which will cause the dust and dirt come into the gear box and then grinding the tooth face. The other is the low hardness of driving tooth, which will increases the wear and tear of the gear.
