转一下派拉蒙的使用说明
“该cam stop的功能如下文：
An adjustable mechanical mechanism called the cam stop is integrated into the Paramount’sright ascension and declination worm block. When properly adjusted, the cam stop preventsthe worm teeth from completely separating from the gear teeth during normal operation(specifically, when the Two Position Switch is in the Track Mode).While the cam stop is set to the correct position at the factory, it can be adjusted under thefollowing circumstances:
The worm separates from the gear during normal operation.
The worm block has been removed or replaced.
Any screw in the worm block assembly has been adjusted for any reason.
翻译一下就是：cam stop 是一个装置，用来调节蜗杆和齿轮的咬合程度，调节合适的情况下，正常使用中用来防止蜗杆和马达完全脱离，如果调节不合适，正常使用中蜗杆就会和马达分离。 虽然我不知道蜗杆是什么，但是隐隐约约感觉和这个调节螺丝有关。
往后我又看到了这段话：
When the cam stop and spring plungers are improperly adjusted, a relatively small torque from to an out of balance payload (approximately 10 ft-lb) can cause the worm to separate from the gear. When this occurs, the worm and gear teeth will make a very disturbing sound as they slide past one another as the axis rotates. This rarely causes permanent damage to the worm or gear, but should be avoided as it can shorten the life of the worm and gear.
翻译一下就是：当cam stop和spring plunger没有调整好，那么相对较小的一个阻力就有可能引起蜗杆和齿轮的分离，并发出恼人的声音，这虽然不会损伤蜗杆和齿轮，但会缩短使用寿命。”
这一套就是赤道仪内部的东东，艾顿的离合是，松离合，电机以及蜗杆分离涡轮让轴自由转动，紧就电机蜗杆涡轮合上，由电机驱动一个小齿轮通过皮带传动带动大齿轮，大齿轮带动蜗杆，蜗杆带动涡轮。
