How to choose a cup machine matching types?

Categories of playing cup machine cooperate, parts should be paid attention to specific working conditions for coordination with the nature, the influence of tightness of to cooperate further summarized. Parts of the specific working conditions including relative motion; Load size and nature; The allowable stress of material. With the length of the surface and surface roughness; Lubrication conditions; The temperature change; On, remove and repair requirements, etc. On the basis of fully consider these factors above, when the design to include lid machine parts with proper adjustment, ask the gap or interference in order to improve the use of machine performance and service life. The base hole system with the main is to determine the shaft of the basic code deviation; Machine for shaft basis, as long as the boxes to the corresponding transformation. According to the requirement and the analysis of the working conditions, get more clear with types, control instance again, can determine the basic code deviation. The clearance fit, due to the basic deviation of the absolute value is equal to the minimum clearance, therefore, shall be determined by the minimum clearance; The transition fit, basically depends on the requirements for and remove the two share in use; Across surplus to cooperate, is determined by the minimum interference. Is reasonable choice to cooperate with the key, so must be on the nature and characteristics of priority to cooperate and cooperate to understand somewhat, and cooperate with the finally selected.
