求翻译：结构造成，变速杆是一硬塑料片，在运动中容易将壳体上油脂挂掉，这是造成R档油脂少的真实原因，但不是变速杆磨损原因点是什么意思？

正在翻译，请等待...

structural causes, variable-speed-under-par is a hard plastic film, during the campaign will be easy to shell grease hanging off R stalls, this is caused by oils and fats, but not the real reason why less variable-speed par point causes wear

The structure creates, the gearshift lever is a hard plastic piece, the fat hangs easily in the movement the shell on, this creates the R files fat few real reasons, but is not gearshift lever attrition reason

Structure, variable-speed rail is a hard plastic, easy to Shell Oil hung out in the sport, this fat little real reason is the r document, but not the speed change causes wear of rods
