A bushing, also known as a bush, is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications. We can supply the bronze and brass bushing.

通常这些衬套用于挖掘机、破碎机、机床、涡轮发电机等设备中。

我们可以为C93200、C93700、C93800衬套提供大量材料，同时也能根据客户需求供应青铜和黄铜衬套。

Usually the big and large bushing made by centrifugal casting or sand casting. We can supply centrifugal casting bushing and sand casting bushing too. Some small bushings can made by continuous casting rod. We can supply them too. Our factories have many centrifugal casting machines and sand casting equipments.

我们的衬套最大直径为2.2米。

最大重量为5吨1件成品零件。

A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear. Two or more gears working in a sequence (train) are called a gear train or, in many cases, a transmission; such gear arrangements can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine. Geared devices can change the speed, torque, and direction of a power source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a non-rotating toothed part, called a rack, thereby producing translation instead of rotation.

变速箱中的齿轮类似于交叉皮带轮系统中的轮子，齿轮的优势在于其齿能防止打滑。

当两个齿轮啮合且一个齿轮比另一个大时，尽管齿的大小必须匹配，但会产生机械优势，两齿轮的转速和扭矩呈反比关系。

我们公司专注于破碎机齿轮和小齿轮，可供应诺德伯格西蒙斯、山特维克H型圆锥破碎机及其他非标齿轮和小齿轮的标准件。
