Runout of a gear can be measured with a dial indicator over a pin or ball placed in successive tooth spaces. On modern CNC gear measuring machines this inspection can be provided in a fully automatic cycle. Runout measurement is used to assure correct backlash and minimum variation of rotary motion.

Park uses the latest helical rack and pinion drive systems for most applications including length and width travel (axis Y and X). For smaller motion applications (Z axis / height positioning), a ball screw system is used. We find the rack and pinion systems to be extremely efficient, durable, and easy to service.

Pinion module of ball mill: Module is the ratio of pitch t to PI (m = t/ PI) between the teeth of the same side of two adjacent gears, measured in millimeters. Modulus is one of the most basic parameters in gear manufacturing. The larger the modulus is, the higher the tooth is, the thicker the tooth is. National standard ball mill pinion module

When an important gear failure occurs, someone becomes responsible for analyzing the failure, determining its cause and recommending a solution. A company can select its own engineer, an outside consultant or both. If a consultant is called in, this should be done as early in the process as possible. Though similar procedures apply to any failure analysis, the specific approach can vary depending

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
