Large quantities TIMKEN one-way bearing production, commonly used model, the sample file block by model adjustment process system; usually use the scale on the machine in a single piece and small batch production, or utilization to adjust. The contents of the adjustment due to the complexity of the workpiece for a simple surface (such as the outer cylinder), usually only adjust the position relationship of the shaping movement; complex surface (such as the spiral surface, involute), we must adjust the forming speed relationship of the movement. Therefore, the adjustment TIMKEN one-way bearing error is caused by a variety of factors.
TIMKEN one-way bearing measurement error should be less than 10% of the tolerance. General measurement error exploits the difference between 10% to 33%, with the tolerance level of increase, the greater the error proportion, that is, smaller the tolerance the higher the error of the proportion of TIMKEN one-way import bearings tolerance of the IT5 above, it is difficult to achieve 10%. Measurement error does not mean that the test tolerances can be relaxed, 10%, but to give a certain margin of safety to ensure user acceptance in accordance with the standard.
TIMKEN one-way bearing parts processed in each process, in order to get the bearings machined surface the size, shape and location accuracy, he will have to machine tools, fixtures and tool adjustment, any adjustment will inevitably bring a certain degree of error. Often require different production volume and processing accuracy of the bearing parts machining, the adjustment method used is also different.
