Technical Field
The utility model belongs to a dipperstick in measurement field, concretely relates to dipperstick of measuring large-scale ball bearing raceway position of wind-powered electricity generation and geometric tolerance.
Background
The wind power bearing comprises a yaw bearing, the pitch bearing is an important basic part of the wind driven generator, and the precision of the pitch bearing plays an important role in the performance of the main engine. Because the machining accuracy of the bearing raceways determines the load carrying capacity of the bearing, accurate measurements of the raceway positions and the dimensions of tolerances are required when machining the bearing.
In conventional measurements, a track position gauge and a feeler gauge are used to measure the track position and geometric tolerance before using a track position and geometric tolerance measuring gauge. The raceway position sample plate needs to be manufactured into a large range size and a small range size, the large range size and the small range size respectively represent the maximum limit size and the minimum limit size of the center distance between the raceways and a base plane, and the R curved surface of the sample plate is manufactured according to the groove-shaped size of the raceway of the ferrule specified by the process. During inspection, the position of the raceway is determined to be qualified by an optical gap method under the light. When measuring the geometric tolerance of the raceway, a clearance gauge is also required to be matched for measurement.
When the roller path position sample plate and the feeler are used for measurement, the roller path position sample plate usually has two types of large-range and small-range sizes, for example, the position of the roller path from a base plane is between the maximum limit size and the minimum limit size, the large-range sample plate and the feeler are usually required to be used in a matched mode, and the feeler is used for measurement while the R curved surface of the sample plate is ensured to be in full contact with the roller path. The conventional measuring method has the disadvantages of being more complicated, having certain technical requirements on measuring personnel, being longer in time consumption and having larger influence on measuring accuracy by human factors.
Therefore, there is a need for a new measuring ruler that can improve such a measuring method.
