Embodiment Construction
[0033] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0034] like Figure 1-5 As shown, a method for determining the machining position of a gear shaft keyway includes the following steps:
[0035] (1) Manufacture alignment process shaft
[0036] Set the modulus of gear shaft 1 and gear 2 to be processed as m (unit: mm), the tooth width as L1 (unit: mm), and the diameter of the addendum circle as d1 (unit: mm); the diameter of the alignment process shaft is D (unit: mm), the length is L (unit: mm);
[0037] Calibration process shaft diameter range: 1.8*m≤D≤2.5*m (unit: mm);
[0038] Alignment process axis length range: L≥L1+d1 / 2 (unit: mm);
[0039] By replacing the traditional gear model 15 with the design of the process shaft, the structure is simpler and the processing cost is lower;
[0040] (2) Install the gear shaft 1 to be processed
[0041] Place the gear shaft 1 to be processed horizontally on the...

The invention relates to a gear shaft key slot processing position determining method. A correcting process shaft is designed for replacing a conventional template; the structure is simpler; the tooth number of the gear shaft can be the even number or odd number; the processing is more convenient; the cost is lower; through the design of two V-shaped horizontal frames, the gear shaft is enabled to be horizontally arranged on a work table; the installation is more convenient and fast; a first correcting process shaft and a second correcting process shaft are enabled to be in a vertical plane by measuring the excircle highest point of the first correcting process shaft and the second correcting process shaft; the operability is high; the measuring precision is higher; a dial indicator is arranged on a machine tool main shaft; the dial indicator is used for determining the position of a boring head or a milling head. i.e., the processing center position of the key slot; the position precision is ensured. The gear shaft key slot processing position determining method provided by the invention has the advantages that the measuring tool is simple; the position detection is more accurate; the practicability is higher; the cost is low, and the like.
Description
Technical field: [0001] The invention relates to the technical field of keyway processing, in particular to a method for determining the machining position of a gear shaft keyway. Background technique: [0002] The gear shaft has a wide range of applications in the mechanical field. In order to play the role of fixed transmission, the gear shaft needs to be machined with keyways. When in use, various types of keys are installed on the keyway to transmit power to the gear shaft. The accuracy of keyway processing directly affects Power transmission and the service life of the gear shaft, the inaccurate machining position of the keyway will lead to unstable operation of the gear shaft, severe wear, and reduce the life of the gear shaft. Therefore, there are strict requirements for the machining position of the keyway, such as figure 1 As shown, it is required that the machined keyway symmetry line intersects with the center of the shaft section, and the keyway symmetry line is ...
