Gauge for measuring maximum and minimum values of intervals between rods of internal spline on part

Abstract

The invention provides a gauge for measuring the maximum and minimum values of intervals between rods of an internal spline on a part, wherein the gauge is easy for manufacturing and measurement and is higher in efficiency. According to the gauge, the internal spline is a small-modulus involute odd-tooth internal spline, and the gauge is of a split structure. A big gauge column comprises a cylinder I with the height I, wherein the height of the cylinder I is corresponding to the height from the upper end face of the internal spline to the lower end face of the part, and the diameter I of the cylinder = (the maximum value of intervals between rods + the diameter of gauge rods) / cos(90 degrees / the number of teeth of the internal spline) - the diameter of the gauge rods. The diameters of threegauge rods are corresponding to the widths of tooth slots of the internal spline. The cylinder I of the big gauge column is located in the part. Two gauge rods are located in any two tooth slots which are located in a 45-degree (central angle) range of one side of the internal spline, and one gauge rod is inserted into any one tooth slot which is located in a 45-degree (central angle) range of the other side of the internal spline, wherein the above two 45-degree (central angle) ranges are symmetric at the center of the small-modulus involute odd-tooth internal spline.

Description

technical field [0001] The invention relates to a gauge for measuring the distance between internal spline rods on parts, in particular to a gauge for measuring the maximum and minimum values ​​of the distance between internal spline rods on parts. The internal splines are small modulus involute odd-numbered internal splines. Background technique [0002] In some mechanical equipment, a part containing a small modulus involute odd-tooth internal spline is used. Such as figure 1 As shown, this part 4 is provided with a large hole 4-4 and a small hole 4-3 that vertically penetrates up and down and the axis lines coincide. The large hole 4-4 is provided with a small mold that protrudes radially inward from the middle. The number of involute odd tooth internal spline 4-1, the diameter of the small hole 4-3 is equal to the small diameter of the internal spline 4-1, and the upper end surface of the small modulus involute odd tooth internal spline 4-1 Height H to the lower end fa...
